Information, Life, and the Big Bang

In 2014 William Dembski published “Being as Communion: A Metaphysics of Information” what he calls (in the introduction) a capstone on a trilogy that began with “The Design Inference: Eliminating Chance through Small Probabilities” (1998) and continued with “No Free Lunch: Why Specified Complexity Cannot Be Purchased Without Intelligence” (2001). In the first two books Dembski spends his time building an argument about the unlikelihood of even simple life’s “information content” assembling itself accidentally on the Earth of some 3 to 4 billion years past.

Considering the Earth could only have supported any conceivable life as recently as 4 billion years ago, life appeared rather soon after supportive conditions developed. Dembski concludes (and you can read the books to follow the math) the probability of that much information assembling itself in that little time is about 1 x 10^-150. The same basic principles hold true for life’s evolution to its present forms adding an extraordinary amount of extra information along the way. Dembski understands Darwinian mechanisms. He carefully evaluates their capacity to assemble such an information pyramid by accident given the possible range of chemical interactions that occur among all the molecules of the nascent biological Earth on up to the present day. He shows again that it is incredibly unlikely for evolution to have been nothing but an accidental combination of mutation and selection.

In his third book Dembski goes on the offensive and focuses not on the unlikelihood of accidental life and evolution to present forms, but its impossibility. He does this by adding to his previous analysis a principle understood and accepted by today’s physics community; “Conservation of Information”. The concept is simple enough. A given system of mass-energy with boundary conditions (including energy flow) cannot express more information than was put into it somewhere.

To see how this all plays out over the history of the universe is the purpose of this essay. Dembski misses something important by leaving open when exactly the information needed to specify life (and next evolution) is added. Dembski happens to believe in a Christian God so he has no problem with the idea of information added to the world at life’s origin. But he leaves open the possibility the information comes not from God, but perhaps aliens. Also open is the notion the necessary information was there at the beginning, at the big bang, leading to a panpsychism, or for that matter that we are living in a computer simulation (another version of aliens) adding information as the code grinds on.

What Dembski misses (or fails to appreciate properly) is that the fundamental discoveries of physics point to a late introduction of the information needed to assemble genuine life. It is my aim here to fill in that gap. Beyond this, Dembski goes on to note that our only experience of information-creation or addition to the world is our own intelligent designs. If information is conserved, and its only source is intelligence, the universe’s initial information must come from some intelligence somewhere. Again this leaves open the possibility of super-aliens, computer simulation, or God. If Dembski is right that information is conserved, then either the universe’s information originates in some intelligence or it was all there from its beginning. If it was there from the beginning, if it was a part of the physical universe at the big bang, where in physics is it found? Does what physics finds at the beginning provide for everything from stars to conscious observers?

Information as understood by physics is of three types, Shannon information, Kolmogorov information, and semantic information. I review these more extensively in my books. A brief summary will do here. Information in all these forms is exclusionary. A hypothetically information-less collection of matter energy, displaying no behavioral regularities, contains within itself a well-nigh infinite potential of future possible states. But there is no such collection because the nature  of matter-energy and the regularities we observe depend on information. Information, beginning with its first expression in “natural law”, restricts present potentials and future possibilities. Our universe, its fundamental material regularities, allows everything from black holes to consciousness, but the possible future states of a present state anywhere in the universe, or for the whole universe, are not infinite.

On a cosmic scale, the specific history of our universe cannot have been much different than it was given its initial information. A stable universe of undifferentiated energy, mint-jelly, or Boltzman brains is ruled out of genuinely possible histories. Information configures matter-energy in some way. This is an important characteristic or property of information, more particularly its causal effect on matter-energy, and is understood and accepted by modern physics.

Claude Shannon developed formula for computing the quantity of information that could be unambiguously (clearly received) over a communication channel having a certain bit rate (number of detectable state changes per second) and some amount of noise. No information channel is noise free in the real world thanks to the second law of thermodynamics. Shannon information isn’t about any particular message, but about how much message a channel can carry. Capacity might be measured over time as it is in digital communications and radios, or in some other measure, for example the length of a DNA segment or a chromosome. The exclusion principle comes in trivially here. A particular message on a channel excludes other messages on that same channel at the same time or in the same place.

Kolmogorov information is about the complexity of a message. The message BBBBBBB is less complex than the message BCADFGE. We can re-write the first as 7B while the second requires all 7 characters in the correct order. Notice that the message FGCBAED is a different message but has exactly the same complexity as BCADFGE. Something like CCCABBF is intermediate in complexity because 3CA2BF requires only 6 characters to specify a 7 character message. Again we note the exclusivity property. Any one message of any complexity excludes all others.

Semantic information concerns what a message (information) means. Normally associated with human mind semantic information is plausibly characteristic of consciousness in general. Life, even without consciousness, displays metaphorical meaning. This meaning is metaphorical because life doesn’t apprehend it. Rather meaning is imputed to life by consciousness, and seemingly always by human consciousness. Importantly to physics, there is no semantic meaning, metaphorical or otherwise, in nonliving, material process. The purposelessness of material mechanism reflects its lack of semantic meaning. “Purposeless mechanism” and “absence of semantic meaning” are two sides of the same coin.

Information expresses itself, one way or another by configuring matter-energy whether the flow of electrons on a wire, persisting patterns, or a recognition of significance (meaning) of a configuration to consciousness. We are now in a position to understand the connection between information, life, and the big bang.

Information, the potential-reducing patterning of some chunk of matter-energy, expresses itself differently depending on boundary conditions, and energy flows. Boundary conditions reflect information in the wider chunk of matter-energy that has causal input on expression in the bounded chunk. Theoretically that would be everything in the past light cone of the inner most bounded chunk, but this is often so vast a space and time that we ignore most of it. The word ‘chunk’ here refers to the matter-energy of some particular region of space and through some bounded time. Every expansion of view to wider and wider spacetime chunks encompasses more matter-energy configured by information whose expression is in turn influenced by even wider chunks. ‘Causal effect’ is a function of forces, fields, with which matter-energy both brings about and with which it interacts. For my purposes, it matters not whether we view matter-energy as the product of fields (as in quantum field theory) or fields as a product of more fundamental matter (charged particles). Both views rest on the same fundamental information.

The first boundary conditions of our universe are the particular qualities of the forces describable in information theoretic terms. These forces restrict what can happen at any given “next instant”. When we gaze into the heavens what we see, the stars, galaxies, clusters, clusters of clusters, interlocking streams of clusters going on as far as our telescopes can peer. At the largest scales, distribution of these substructures appears random, but just inside the largest scale, there is clearly an expressed arrangement. The matter-energy of the universe is not distributed randomly at all scales. Our particular arrangement, can be described as a measure of complexity; Kolmogorov information. That state, any given “state of the universe”, changes into new states. The entire universe has a capacity, a limit, at which the evolving information expression advances. There is a limit to the rate at which change in the universe takes place. The universe has a Shannon information limit.

Cosmologists and physicists have long recognized the structures of the universe are, over-all, a natural outworking of a tension between positive energy expressed as temperature and pressure and negative energy known by its more common name, gravity. A cold cloud of hydrogen gas and dust floating around in space has more entropy than the star which eventually forms from it. It is gravity (negative energy) that reduces entropy in the gas cloud by consolidating it, restricting the freedom of its individual atoms to be anywhere in the much larger region of space that was the cold cloud. At cosmic scales, gravity is the great reducer of entropy. It does this by folding space around mass. Mass migrates inward (falls) toward the center of the folding which happens to be always what we call the “center of gravity”.

Taking entropy out of a system like this makes it more difficult for photons to escape it. Folding space compresses electromagnetic forces (constraining photons) heating the contracting gas producing more rapid particle motion, raising temperature, and increasing pressure. Eventually the gas heats up enough that fusion occurs and the resulting release of positive energy balances ever-present negative gravitational energy. But why does the balancing out occur here at this point? Why isn’t gravity strong enough to overcome fusion and keep folding space until a black hole forms more or less immediately?

The balance occurs at fusion, and gravity and pressure combine to make all the structures of the physical universe, thanks to the cosmological settings. The causal regularities we call “natural law” rest on the settings. The settings (there are some 20 of these seemingly arbitrary values among them the “cosmological constant”, the value of the “Higgs field”, the “fine structure constant”, and the “proton-electron mass ratio”) limit the ways in which matter-energy can interact. The particular interactions that occur are a reflection of the settings under boundary conditions holding at any given place and time. The settings are the minimal information present at or shortly after the big bang.

The star balanced at fusion expresses the same information as the cold gas cloud from which it formed. Both are deterministic expressions, patterning in behavior, of the same settings. At the opposite end of the size scale from stars, at the building blocks of matter (the fundamental particles of the present Standard Model) to molecules the same settings restrict behavior. At the small scales the important forces are the electromagnetic (molecular scale), and the strong/weak forces (nuclear scale). The same settings pattern matter on a different scale from the cosmological under differently relevant, microscopic, boundary conditions.

When mass-energy at a macroscopic scale is somewhere in thermodynamic equilibrium its state expresses the information present in the settings under that equilibrium. For the expression to change, to evolve, boundary conditions must change. That change rests causally on the flow of energy through the system. Change is also inextricably bound up with time. The seemingly simple notion of time is anything but simple. Is time something fundamental, perhaps even more fundamental than space (Unger/Smolin “The Singular Universe and the Reality of Time” 2014), or does it emerge from (and amount to) an averaging (as temperature is an averaging of molecular velocity) of the change in the quanta of space (Carlo Rovelli “Things Are Not as they Seem” 2016)? Does time exist at all, perhaps being nothing more than a meaning (semantic information) consciousness associates with measuring the rate of change (Julian Barbour “The End of Time” 1999). For purposes of this essay, nothing depends on this controversy. Time, one way or another, is an ingredient of every boundary condition and energy flow throughout the universe at all scales.

Significantly, when change occurs ordered patterns emerge. A star is ordered in this way compared with a gas cloud We note the same phenomena in columns of bubbles rising in the simmering water in a pot. The ordering in all of these cases is the result of a coupling between the settings, the boundary conditions, and energy flow. For my purposes below, I lump energy flow into the boundary conditions but the reader should always be aware that if changes in information expression are occurring, energy is somewhere flowing through the system. There are a few scientists who claim this emergence of order is enough to explain the eventual appearance of life, but this cannot be true. As I discuss below, life exhibits a new kind of ordering that never appears in non-living phenomena; and ordering requiring information not present in the settings directly though of course it remains consistent with them.

All the phenomena of the universe from the layout of the galaxies and down to the behavior of atoms in crystals and amino acids directly express cosmological settings under different boundary conditions, and these in turn also rest on the settings. The settings are the information present at (or within a second) of the big bang. They are information because they do what information does, they restrict or exclude possibilities by constraining what they pattern. The behavior of quarks, protons, neutrons, electrons, or the effect of gravity, isn’t random. The settings restrict the values of the forces and those constrain the behavior of everything else from quarks to superclusters.

The limits, patterns of behavior, vary as conditions change, the changes themselves “caused” (some would prefer “unfold into”) by those same regularities. Two seconds after the big bang all the settings were already in place. The strong, weak, and electrostatic forces had to exist as they now do for there to come into existence protons, neutrons, electrons, and a few nuclei of helium and lithium. Given the enormous pressures and tempretures of the environment (boundary) of the big bang in its first seconds, the building block particles where the expression of the settings. Given 14 billion years of evolution, we have the universe of today, an expression of the same settings. Up to a point.

If the Conservation of Information theorem is correct the information respresented by cosmological structure or molecules had to be put into the universe as it has evolved over time, or it had to be there at its beginning. Cosmologists today mostly believe that this information was in fact all present from the beginning, or at least within a few microseconds of the big bang. Physics and cosmology has convincingly shown the settings plus gravity explain the present structure of the cooled down universe. Granting that all of this information was present at or near the beginning from where did it come?

At first cosmologists thought perhaps the values had to be what they now are; not arbitrary but rather forced out of the boundary condition of the big bang. But a hundred years of theoretical effort to derive them has failed to prove the necessity of these particular values. The now fashionable answer is the values sprang (quickly evolved) into their values purely by accident, by sheer coincidence. Recognizing the improbability of this, cosmology and physics have spawned many theories of multiuniverses (Max Tegmark “Our Mathematical Universe” 2014) in which the settings take on all manner of random values. The idea is that given billions of such universes, it is not inconceivable that one would occur in which the settings took the values we observe. That they did so here makes the eventual appearance of observers possible and it should not be surprising that observers find themselves existing in such an unlikely universe. This idea, called the “Anthropic Principle” (Brandon Carter Krakow symposium 1973, Barrow and Tipler “The Anthropic Cosmological Principle” 1987), must be at least trivially true. Since we exist, it must be possible for us to exist within the constraints (remember information restricts possibilities) of the cosmological settings.

Of course there are plausible “intelligent alternatives”. God might have constrained the settings to obtain the physical universe we occupy, a physical universe supporting eventual life and consciousness. A few honest physicists have noted the unlikeliness of the settings would not be surprising if there is a God. Besides God, the intelligent alternatives coming from science have tended to pure science fiction speculation of super-aliens (effectively demigods) or perhaps computer simulations (also implying super-aliens). Such speculative alternatives all involve beings like ourselves only having far advanced cognitive abilities and technology. Such beings either live with us in our universe or inhabit their own universe outside our own. Either way, all the cosmological origin questions remain. But multiuniverse theories require only more physics; perhaps other physical universes of some sort. This is why the science community prefers such otherwise unverifiable speculations. But they are not better explanations. They do not, for example, extend to consciousness very well.

There is something more to notice about information re-expression based solely on the settings and evolving boundary conditions. All of these expressions, that is everything governed primarily by gravity as the source of negative energy, electromagnetism, or nuclear forces are repeating structures. Every proton is identical to every other proton, and all the galaxies, while differing widely in specific shape and size are gravitationally bound rotating collections of stars very often influenced by a large central black hole (dark matter is a part of the boundary conditions forming and maintaining these structures). If you consider any given cubic meter of a star’s interior at some distance between its center and periphery, it is much like any other cubic meter of that same star at the same distance from the center.

At almost the opposite end of universal size scales, the most informationally complex structures are homogeneous crystals and relatively simple organic molecules like amino acids which themselvs will form crystal structures under the right boundary conditions. There is a large negative entropy difference between a freely floating gas of hydrogen, carbon, nitrogen, and oxygen, and an amino-acid composed of those same elements. But that reduction, purchased in the molecular case with the energy of electrostatic bonds, is nothing more than a structure that arises automatically thanks to the settings under particular boundary conditions. From the crystallization of water (ice) to the formation of amino-acids, as with gravity, entropy reduction is associated only with the production of regular repeating structures whose variation depends solely on the nature of the settings and boundary conditions which are themselves the result of the setting and their own larger-scale boundary conditions.

This situation changes dramatically when we look at life. Galaxy formation, stars, and amino acids are an immediate response to entropy reduction caused directly by gravity or electrostatic forces under specific conditions. Once any of these arise they become stable. Only changing boundary conditions alter their stable states. Even dynamic but presently stable stars are in a stable equilibrium condition with pressure balancing gravity.

But living systems differ from any nonliving information expressions in several ways. Their stability is never merely a simple equilibrium, but rather the product of many interactions dynamically reducing entropy in the living organism over all. Of course living processes cause entropy increase in the environment, the boundary within which life operates, and there are living processes that spend heat in support of neg-entropic mechanism. Life exhibits a persistent battle against entropy and is never in internal equilibrium. If a living organism comes to complete equilibrium, or its entropic activity dominates, the organism dies. More importantly, life’s neg-entropy mechanisms achieve their effect not by the simple surrender to the consequences of the settings but rather to active mechanisms that map or translate information from one form into another. Living systems are filled with little engines that map information from one form into another reducing entropy in the system over all as a by-product. No comparable mechanisms exist in the nonliving cosmos.

The most familiar of these living mechanisms is the multistep interaction chain, associated with many intermediate structures themselves built up out of the same process, of mapping information in DNA to proteins. Obedient to the Conservation of Information theorem, this creates no new information. Rather, information is mapped from one expression to another. But the mechanism itself, a mapping engine, is new. None of this works apart from the limits imposed by the settings. But unlike stars, life’s entropy reduction is not a direct outcome of the settings, but of an entropy reducing transfer of information from one form to another.

The complexity of life frames a further limit on the space of possibility within the restriction imposed by the settings. It amounts to new information besides the settings alone. A protein’s biological functionality is not merely the result of its electostatic forces, but also its physical shape. True, the shape is the result of electrostatic forces, but an identically force-balanced molecule of a different shape will not work. Many differently shaped molecules might have identical force balances. The biological activity of a particular shape is a restriction not found in the settings alone. Life’s information is a restriction on top of a restriction and that demands more information. Where did this more come from?

Once again science, this time biology down through chemistry to physics, declares that it was all, like the settings, a lucky accident. Yes, they admit, unlikely, but not impossible and if it hadn’t happend on Earth, we would not be around to comment on it. In his first two books, Dembski explains just how unlikely such an accidental assembly is; thousands of different translations, hundreds of thousands of molecular arrangements, functioning as an integrated system, a living organism. In his third book Dembski argues that the information difference between nonliving processes and the simplest conceivable life (simpler than anything we find on Earth today) could not possibly come to exist accidentally. If life’s arrangement cannot be a direct product of the settings alone (the only information present in the big bang and throughout the evolution of the nonliving cosmos) its accidental appearance would be a violation of the Conservation of Information principle. What Dembski misses (at least I do not remember him mentioning it) is that life’s entropy reduction mechanism, complexity translation, is nowhere else exhibited in the interactions of the nonliving cosmos. From intergalactic clusters to amino acids none of the accumulated information is carried through translation mechanisms. It is all the immediate expressions of the settings under specific conditions.

For science to declare the one “life origin” event we know of is an accidental product of the settings plus boundary conditions directly is question begging and most scientists know this. “Accidental” is not a valid generalization from a single observation. Even if life on Earth originated on Mars (some cosmologists do assert this is a possibility), the question of how Mars’ life began still stands. Plausibly however, life-harboring planets around other stars are effectively isolated from one another. Life on such worlds originates and evolves independently.

What a discovery of genuine life on the planets of other stars would mean depends on what we find. Finding something indisputably alive but much simpler than the simplest life on Earth, would lend credence to the view that initial assembly might be accidental. Perhaps some life is so simple (something true also of long vanished early life on Earth) that it is not so unlikely after all. But if what we find on one or even dozens of other worlds is that all life is complex, different perhaps but on the same order of complexity as the simplest life on Earth, the hypothesis of “accidental appearance” gets all the more problematic. If, as Dembski claims, the chance of life springing into being accidentally on Earth is 1 x 10^-150, it is half as likely to have happened twice, let alone multiple times.

The rest of Dembski’s argument is straightforward. Human beings, observers in the universe, know of (that is experience and observe) only one source of new information in the universe; intelligent agency. For materialists to claim that this too, that is what we experience subjectively as intelligent agency, is nothing more than an outcome of the settings and boundary conditions, begs the same question as regards life. The “only example one has” of anything cannot be the ground of a valid inductive generalization. If the only life we ever find is complex enough to be highly unlikely there are only three possibilities. The absurdly unlikely happened, there is something fundamental that we are missing in physics, or life’s information came from the outside, from intelligent agency. In all my writing including this essay I have taken for granted there is not something fundamental missing in physics.

Physics may not be finished thanks to the problem of unifying gravity and quantum mechanics, but it has nailed a few fundamentals. It has adequately dispensed with the idea there is an “invisible force” that pushes physical regularity toward the assembly of living information. We find nothing of this in classical physics or quantum mechanics. If physics is correct as concerns its own causal closure, then life’s information had to be added at a place and time when boundary conditions were supportive. If some intelligent agency acted at life’s origin (perhaps on many worlds) then the same agency’s action, to fix the settings, at the big bang would not be at all surprising. The settings are fixed as they are in support of [eventual] developing boundary conditions conducive to life’s origination.

This notion must also apply to life’s evolution on Earth to the point of emerging consciousness, and in particular a personal consciousness (discussed at length in other essays on the blog). Over a mere 3 billion years an amazing quantity of new information (Kolmogorov complexity) assembles from primitive cells to organisms having subjective experience. Subjectivity at least begins with the higher animals, but it makes the transition into “observer status” only in human beings. Animals observe their environment in the sense of integrating sensory experience in a subjective gestalt. But being an OBSERVER implies more than mere observation, it implies recognition of meaning implicit in observation but not of the observation as such. This brings me to final consideration of semantic information.

Semantic information, taken most broadly, is prelinguistic, but not preconscious. A lion easily distinguishes between a zebra and the tree next to it. It grasps the zebra is potential food and the tree is not. The discrimination between zebra and tree has meaning to lion consciousness. Given memory and subjective experience an association links ‘zebra’ to the relief of hunger. Semantic information is transferred not by translation from one physical carrier to another, but from some such physical state to a subject. Meaning is meaning to a subject. Compared to biological information, semantic information is one step further removed from the settings. Many discrete sets of biophysical states ground a particular persisting consciousness, while different conscious experiences follow from similar biophysical states. Semantic information is largely independent of the physics underlying it and exists only to consciousness.

The uncoupling of semantic information from physical information continues in human consciousness. A zebra means [potential] food to a lion whether it is hungry at the moment or not. Both lions and humans apprehend meanings in this way, we are after all animals. But human beings not only apprehend meanings, they also abstract and evaluate them. Abstraction and evaluation combine to suggest meanings not immediately apprehended. This (and our volitional power to control our bodies) underlies our capacity to put new information into the world, literally to pattern matter-energy restricting its future potentials. Humans alone are capable of adding information, arising in subjective abstractions, to the world. Lions are not. We create art, and airplanes. Flying airplanes are like biological activity in the outcomes of information mapping engines. A successful mapping creates not only a biologically active molecule, but one that functions in a role specified by biological demands. A flying airplane signals a successful combination of semantic information and physics (purposeless mechanisms resting on the settings) whose proper role is specified by subjective intent to build a flying machine.

In a living cell there is nothing in the chain of events from DNA to a shaped protein that relies on anything other than the basic forces whose fundamental information, present at the big bang, is the settings. In this case, the electrostatic forces are dominant, but everything has its effect on the outcome. There does not appear to be anything in life that originates outside the physical world. As with the settings, once information is put in somewhere, life’s day-to-day operation exhibits nothing but outcomes explained by the forces (settings), and boundaries now including life, that cell, itself. But life’s delicately balanced self-maintenance does not address the issue of how its information originates. If the Conservation of Information theorem is true, then not only was its accidental assembly unlikely, it is impossible.

Individuals are free, of course, to believe life’s origin and evolution was accidental. But the argument that they were nothing of the kind is clearly plausible, even reasonable compared with much speculation from materialists. When we arrive at human beings, a new power springs from life through consciousness. Not only is there a mapping from some physical “state of affairs” to a meaning apprehended in consciousness, but uniquely, humans can map abstract meanings from consciousness to the world. Abstraction capable language marks the final separation between information and the settings.

The word ‘palo’ in Spanish means ‘tree’ in English. Either might refer to some particular tree or to the class or kind ‘tree’, and both are equally compatible with the settings and boundary conditions up through all of biology. All human languages are of course compatible with human biology everywhere on Earth. Expressing a single abstract meaning in different languages demonstrates the complete decoupling of semantic meaning from the settings. Completing the decoupling begun with life and continued in animal consciousness grounds both human free will and our power to create information.

This capacity, the free-willed intelligent creation (by arrangement of matter-energy) of new information, demands new information. If everything that happens in the universe expresses information, such novel power rests on information not previously present; information added not to matter-energy directly, but to consciousness. I go into what this implies in more detail in my books and the blog essay “Why Personality?”

All the information from the settings to life, supposing they come from outside physics, might conceivably (however implausibly) be the work of aliens, or perhaps we live in a computer simulation. Consciousness poses a special problem because unlike the universe and life, it is plausibly both real and nonmaterial. A corollary of life’s physical nature is that living process isn’t intrinsically conscious. Nothing about biology, however complex, suggests an emergence of subjective experience. It isn’t clear that any subjectivity can emerge from a causally closed physics; not even accidentally given infinite time! Human consciousness poses an additional problem. Even the highest animal consciousness does not display an ability to configure the world in novel ways based on new meanings conceived first (and not merely apprehended) in consciousness!

Human beings can shape the world based on thoughts whose origin has little direct connection to immediate sensory experience or memory. Of course our creative thinking includes apprehended meaning. But human creativity goes beyond experience to first postulate new, associative meanings, and then test their validity (truth content) by configuring physical subsystems that function (like shaped proteins) in their intended roles. Art, philosophy, and technology are all predicated on the validity of meanings originating in consciousness.

If aliens did this, from life (at least) to subjectivity capable of original creation, directly or in a computer simulation, they would stand in relation to us much as religion’s claims for God. Not entirely, for it is not an entailment of the alien hypothesis that aliens be for example omnipotent. If however we live in the matrix, a computer simulation, then omniscience, omnipotence, and omnipresence within the context of the program are reasonable inferences.

If the aliens are a product of this universe, the matter of the settings, and how the alien life started and evolved, appears. The alien hypothesis settles no philosophical issues. If aliens created the universe itself, and it is not a simulation then their universe must be something outside, apart from the physical as we see it from inside our universe. Even if one insists this outside is physical it cannot be “our physical”. There must, in this view, still be something outside our universe. But none of this matters because if any of these speculations are even remotely true, then something or someone added information, at least beginning with life if not the big bang, to the universe, our universe! It doesn’t matter if the agency is divine or not or if the information came from aliens inside or outside the universe. It isn’t necessary to assume that this agency must be purposefully intelligent. But evidence at least suggests that it exhibits all the characteristics of purposeful intelligence as we observers experience it.

If any of this speculation is true, physics must still give up the idea that “no such information came from anywhere”. There is some irony here. The speculation taken most seriously by the materialist community is that all we know as our world was genuinely an accident; precisely the “no information from anywhere” hypothesis. The irony is that this hypothesis is the one least supported by all the evidence, even the purely material evidence of life. Life is the first, partial decoupling from the settings. That decoupling depends on information not present in the settings. If the Conservation of Information theorem is true, life’s information had to come from somewhere other than physics.

There is nothing in physics, nothing in the strict causal closure of the physical that is incompatible with information coming in from the outside. Purposeless mechanism (a valid insight of physics) and purposeful information added by an intelligent, at least intelligent seeming, source are not incompatible. This is almost a trivial truth as concerns human experience. We configure purposeless mechanism (mechanism of the physical world) with our own purposes all the time. Our entire technological history not to mention art, science, and philosophy begin with that ability. If physics and intelligent agency get along as we experience them, and if our universe is everywhere basically the same, there is no reason to insist that agency characteristic of intelligence did not add information to the universe possibly starting with the big bang. Only an agency outside the universe explains everything, where all the information came from, including the universe, the settings. Physics cannot address itself to the nature of that agency because whether it is physical or not, it is not a part of our universe.

Why Free Will?

Let’s begin with physics. I love physics! The mechanisms underlying the physical universe in which we live are fascinating to me. What most strikes me about these mechanisms is that they are purposeless. Underneath the deterministic behavior of macro-physics (expressed today in classical Newtonian Mechanics, electro-magnetic field theory, and both special and general relativity) there is the quantum realm in which a true randomness replaces determinism. This is important. Randomness becomes determinism as quantum phenomena emerge into the classical. Neither exhibits any evidence of purpose in its mechanism.

Authors note: Since writing this essay I have come to learn and understand that quantum phenomena are not random, but indeterminate. The difference is technical and has to do with there being a definite and determined statistical distribution of quantum outcomes. The outcome is NOT determined, but the distribution of outcomes is. That’s indeterminate! The argument in the rest of this essay does not, however, depend on this difference.

If there is any evidence for the existence of God it does not come from physics. Oh we can observe the universe, note its fantastic propensity for delicate structure from strings of galaxies to the operations of the living cell, recognize beauty in it all, and suppose that all of this was brought to be in a purposeful way by a God having some purposeful end in view. As it turns out, this association might be true and not interfere with the progressive discovery, by physics, of purposeless mechanism. We attribute to God the power to paint his purposes on the canvas of purposeless mechanism. But when we get down to the physics of it, we discover not that God couldn’t do this, but that God’s hypothetical purposes are not needed to explain the effect. Gravity, heat, and the values of the physical constants together can get the job done. Of course that these things got this particular job done (including life and what has followed from it), and not some other less amazing result, was simply an accident as far as physics is concerned. But that’s ok. Physics’ job is to uncover the mechanisms, not to pronounce upon their justification in a wider context.

The evidence for God’s existence, if it comes from anywhere, has to come from consciousness, the fact of a libertarian free will (at least in persons), and the detection of values – truth, beauty, and goodness. All of this is discussed in far more detail in two of my books (published in Amazon Kindle format), “Why This Universe: God, Cosmology, Consciousness, and Free Will” (2014) and “God, Causal Closure, and Free Will” (2016). I’m not going to reprise those arguments here. Let’s assume that what I take to be “evidence of God’s existence” really is the evidence we need, at least provisionally, to accept God’s reality. The question I want to address is what the combination of a purposeless physical and libertarian free will accomplishes and how it helps to answer the question, why this universe? Why are free will and purposeless mechanism juxtaposed?

The Nature of Free Will

Free will comes down to our capacity to initiate novel chains of causation in the physical. Chains whose beginning cannot be attributed to an infinite regress of physical causes. The higher animals also have something of this power, but human-initiated causal chains, are novel in a much stronger way than chains initiated by animals. If a lioness hunts and kills a zebra for food, feeding parts of the carcass to her cubs, there are causal chains precipitated from those events, chains that would be absent if the lioness misses the zebra(or chooses to leave it be), while other causal chains would ensue – perhaps her cubs would starve.

Animals can manipulate purposeless physical mechanism to initiate different futures by manipulating pre-existing agents and processes. In doing this, they introduce purpose into universe process. For animals, such purpose is limited to manipulating what already exists. The zebra already exists when the lioness sees it. She can leave it alone or hunt it. If she hunts it, she can succeed or fail. The result is a still-living zebra, a dead zebra, or a tired (but still living) zebra. None of these things would be new in the world.

Humans can also manipulate existing objects and processes in this way, but we can do something animals cannot. We can create genuinely unique objects and processes. These begin with ordinary pre-existing things, but we are capable of assembling such things into new things that did not exist before. Human initiated causal chains not only rearrange what existed prior, but from that re-arrangement build up new things whose effect on the world is entirely novel, emergent, an effect that never existed prior to the object (or process’s) creation.

Human purpose imposes an entirely new level of order on deterministic physics, an order that did not exist prior to its imposition. In Aristotelian terms, mind, including animal mind, adds “final and formal cause” to the universe.  But in the animal case, both are restricted to the biological demands of the organism. Human mind, our capacity to create new realities, novel orders on top of deterministic mechanism, is novel in itself. We create much that is but tangential or has nothing whatsoever to do with our immediate biological requirements. Human volitional choosing incorporates both abstract time and [sometimes] the values into its purposes. Something no animal can do.

Let’s imagine an analogy. God is a master artist, and we are his beginner student. The master can work in any medium, any paint, on any surface, sculpt in stone, clay, or bronze, compose and play magnificent music in any style, write masterpieces of literature, write, produce, and act in dramatic work. One might notice right away, that art is in fact one of the channels through which humans use free will to create what is new, but here the art analogy stands for novel creation in general. As beginning students of our master, we are given only one medium on which to create, a canvas which happens, in our case, to be a purposeless physics. Further we are given only one physical instrument with which to create, that being our bodies. It’s pretty obvious how the analogy goes. We impose purposeful order, the purposes being chosen by ourselves (freely) on the canvas we are given, the physical universe, with the only instrument we have, our bodies – and other instruments that we create using them.

But what purpose are we to impose? What are we to create on the canvas that surrounds us? We began by creating simple tools, stone axes, and clothing. A million years later and we have reached atomic bombs, aircraft, computers, vast scientific instruments, medicines, and more. Much of what we have created has, over all, benefited human life on Earth, or at least some portion of it. Much of course has brought also misery on a scale not imagined by our stone-ax-wielding ancestors. Here is where the values come back into this picture. In the theistic view, values, truth, beauty, and goodness, are not invented in human minds, but detected by them. They are the compass, a suggestion from the master (keeping to the art analogy) as it were, for what sorts of novelty we are supposed to create. But for free will to be genuinely free, the master can suggest but not dictate the creation.

Why not? Surely many masters dictate to beginning students. Here I have to leave my teacher-student analogy. In our real case, in the real world, the decision as concerns what to create lies only and exclusively in our will. Why should that be? Given that this can, and has, resulted in much misery throughout human history. Couldn’t God have arranged everything so that we were free in just about anything except as concerns the kinds of choices; choices that initiate causal chains having direct and deleterious impact on other human beings? I have to suppose he could have so arranged things, but the restriction must have an impact on the intended outcome (and God would know exactly what the difference would be) such that it wouldn’t work out to be what God intends.

How can we begin to say what God intends? In fact though, supposing God to be both infinite and [infinitely] good, allows us to say something at least of what must be true of what God wants. It must be the most repleat possible manifestation, in the physical, of God’s values, pointers to his intentions, which for now we know only as our dim detection of truth, beauty, and goodness. This idea is expressed by the phrase “best possible universe”. Whatever else he might want, God must want the “best possible universe” that can be made. Clearly this is not the case now, at least not on Earth. This place is literally hell, tormented existence, for billions of people alive to day, and countless more who have come and gone since human history began. If we can imagine better, so can God.

Of course we do not know the status of life on other worlds, but a generally inhabited universe is easily supported by theism. More importantly, even as concerns this world, time must be factored into the eventual emergence of “best possible universe”. Since “God’s will” must be the highest truth, beauty, and goodness, a “best possible universe” emerges in time when every creature freely chooses to do that will to the best of its ability at any given stage of that creature’s life. Doing God’s will means doing that which increases the value content of the world’s particulars.

Human beings (value-discriminating personalized minds on this and other worlds), must make this choice of their own free will. They must choose purposes and create novel reality based on what they perceive to be alignment with the values! God cannot create a logical contradiction. He cannot make a square circle. Nor does God do anything purposelessly. If the best possible universe could be brought about without free will and its attendant potential problems (evil), God would have done that.

What God must want (at least. among other things) is that world resulting from that choice when the choice is utterly free and made by everyone. Apparently, those people will live in the best possible universe and it will be better, even than a universe that evolves through the same amount of time but in which humans were not free as concerns value entangled choices.

So there we’ve got the whole thing sort of summed up. To make the “best possible universe” human beings, all of them and for all future time, must (and will eventually) choose to align themselves with the values, with truth, beauty, and goodness, and all of that happens to come out to God’s will (metaphysically) and love in human experience. God could, by himself, have created a fantastic universe. But what seems to be the case is that an even better universe can (and will) come from a partnership between God and creatures who detect values and freely choose to incorporate what they detect in the causal chains they initiate. This cannot happen unless human beings are actually free to make those kinds of decisions. That means they are free not to make them, and that, in turn, leads away from the best possible universe, at least temporarily. I will return to this last point below.

The Relation between Free Will and Values

I want to say something more here about values, in particular how and why they figure in this process of human instantiation (literally making-an-instance-of) of God’s will. Three things are traditionally taken to be values as such; truth, beauty, and goodness (see “What are Truth, Beauty, and Goodness”). Separately, they are the root concepts of three major branches in philosophy, epistemology, aesthetics, and ethics respectively. Within these separate domains there are outcomes or instantiations within the world of values, and these outcomes are taken to be “of value” because they do in some sense embody one or more of the core values. A true proposition is “of value” because it instantiates truth, fairness is “of value” because it embodies goodness. Beautiful things are “of value” because they are beautiful, etc. Truth is value in the intellectual domain, beauty is value represented in physical, while goodness is the value of personal choice, the value of interpersonal relationships.

Taken together, all the values raise the same metaphysical question: from whence do they come? In rejecting any theological metaphysics, most philosophers assert one or another version of human invention of values. Phenomenally, they are entirely subjective although it might turn out, as we share much of our phenomenology, that they come out roughly the same in most persons. Their subjectivity is under normal circumstances constrained to a range. Your notion beauty might be different than mine, but it is rare that I would find beautiful what you find repulsively ugly. Truth we normally take to be somewhat more objective, less tolerant of subjective interpretation, while our sense of goodness falls somewhere in between beauty and truth. This view seems to explain how it is that while most persons seem to have some shared sense of values, many do not. Not only are there persons who perceive values in almost exclusive terms, there are those who do not appear to respond to them at all.

Importantly however, as much as philosophers have tried to ground “objectivity of value” on our shared biological experience, such grounding offers no reason why any one individual should pay attention to values. If on the whole the universe is purposeless, its only purpose being our purposes, who is to say that your purpose, to love others, is any more right than my purpose, to make all people my slaves? You might argue that more people will come our happier given your purpose. I might even concede your point but note that if values are invented by us, in the end, the happiness of the many is not any more intrinsically valuable than the satisfaction I derive from being slave-master of all. As concerns the purposeless universe, from my viewpoint, neither outcome is intrinsically to be preferred. If values are metaphysically subjective, the happiness of others can be justifiably irrelevant to me.

As already noted, in the theistic view values are not invented they are detected. They are extrinsic to us, a signal as it were from God, detected by human (and not animal) minds. Now as it might happen, minds are not equally sensitive to this signal, sometimes altogether, and sometimes separately. This explains some of the variation we have as concerns them, but more importantly, however well we perceive them, we are free to ignore them and this explains the rest. Of course our detection capability is imperfect as is our capacity to effect what we detect on the universal canvas. Importantly, value’s metaphysical objectivity provides the reason why any given individual should pay attention. Your purpose to love is in alignment with God’s will, while my purpose, to make slaves of all, is antithetical to it! “Knowing the end from the beginning”, God’s will must eventually come to pass. Your free will choices are dedicated to assisting in the bringing about of that end, precisely the use God (apparently) foresees will result in the best possible universe! My will, by contrast cannot possibly contribute to that inevitable outcome. It must be, that while I might appear to gain something for a time, that which is gained has no intrinsic value. It incorporates nothing of truth, beauty, or goodness. This has consequences not only for others made miserable, but for me. I will deal with some of these issues in a future essay.

There is another important property of our relation with values. Our value-entangled free will choices are the only choices about which we are absolutely free. As such, they are the crucial link in the chain of process that (apparently) brings God’s will into the world; evolving purposeless mechanism into the best possible universe. All our other non-value related choices, while yet free, are hemmed in, constrained by what we can do physically with our tools. Only as concerns value-laden choices are we free in an unconstrained sense. It is with respect to this freedom that we become agents of the connection between God’s will and the physical universe. True our capacity to instantiate value in the physical is limited by all the constraints that limit our other choices. We can act only with our bodies and the tools created with them. But the choice to attempt that instantiation (or to refuse to do so), however imperfectly, is radically open.

The best possible universe not only requires freedom, it requires radical freedom. Given that we are otherwise constrained to the physical, it is only with respect to value-entanglement that we are radically free. It isn’t merely through choice that we incorporate God’s will into the world, it is specifically through choosing to instantiate the values! The values are the link that connects God’s will and purposeless mechanism with human freedom. It is by following their compass that human choices remake the world over into God’s image of what must be the best possible world.

None of the foregoing is meant to suggest that the process of human partnering with God in the making of the best possible universe is straight forward. Although we are radically free with regard to attempting some mapping (instantiation) of value as we perceive it into the physical world, the process of carrying out that decision depends on our skills utilizing the same tools, starting with our bodies, that we employ in carrying out any other action-demanding decision we make. As concerns the individual’s relationship to God it is said that only the motive of the agent is important. An omniscient God knows us each most intimately, and would be an unfailing discerner of motive. The consequences to the individual of such choosing can be the subject of another essay, but I note that as with many kinds of physical action, practice contributes to skill.

As concerns the world however, that is as concerns the effect of some individual act on the world, much depends on both the skill of the actor in effecting the action, and also on the state of the world (including other actors) in which the action is set. Although this last is outside the control of the actor the two arenas do interact. A part of what constitutes skill with respect to a particular act at a particular time takes the state of the world into account up to some limit of which the actor is capable. I’ve already noted that we do not detect value perfectly. As some people have better eyesight than others, some are better value detectors. Detection capacity contributes to an individual’s skill as concerns value instantiation, but it is the state of the world that underlies the apparent relativity of values as they manifest in the world.

Any attempt at value instantiation that impacts more than one or a few near-by persons comes to interact with a wider milieu of states and personal actions that affect its outcome. On a crowded world, vastly different economic, social, political, and geographic circumstances, along with their specific outworking as concerns any particular individual, guarantees that no attempt to do good, aver truth, or enhance beauty will have straight forward and universally beneficial effects. This can be true even as concerns two individuals! If I give some money to two hungry people on the street one might buy alcohol while the other buys needed food. True I might have been more skillful in my choice of action, perhaps bringing food instead of giving money, but even in this case I have no way of knowing (unless I subsequently follow these individuals) how my meager attempt at bringing some goodness into the world plays out.

On larger scales the problem becomes more severe. Ethiopia wants to dam the headwaters of the Blue Nile, electrifying parts of the country for the first time, bringing economic opportunity to millions. But if the dam is built, the flow of the Nile will be much reduced and those nearer the mouth, in Egypt, will loose economic opportunity and their food supply as the river level falls. These kinds of problems are playing out all over our world, and anything the world community agrees to do as concerns these things invariably helps some and harms others. This would remain true even if the community’s motives were purely moral. As it happens, many more motives are typically involved.

The values are not a formula for success in building the best possible universe. They are a compass pointing in a direction but otherwise incapable of yielding specific measures having desired outcomes. Those measures, their implementation and adjustment as one comes to know their outcomes, is our collective task. The compass is important however, and for reasons noted above recognizing its objectivity is also important. But all of that only gets us to justifying the demand for action and that the action be motivated by a desire to benefit those affected. The rest, the creativity, will (personal, economic, and political), and specific action to take are all entirely up to us. Not only is it our mission (at least as concerns God’s intent) to bring values into the world we must learn progressively how to do it! Part of that learning experience involves comparing outcomes of acts back to the compass! But this would make no sense, it would not be guaranteed, or even likely to work, if the compass were not objective.

Theodicy: Free Will and Evil

I have covered this subject in great detail in my first and third book. Here I can only summarize it all. Philosophers divide this problem into two parts, natural and human-caused evil. Natural evil is an oxymoron. The universe God needed includes physical events (for example stars exploding, earthquakes, and naturally-evolved diseases, that harm (or can harm) human beings. Death by gamma ray burst, earthquake, or disease are all bad for us, but they are no more technically evil than are the natural events that give rise to them. No one would assert that an exploding star is morally culpable.

Philosophers also accuse God of being evil for just this reason. Why would he create a universe in which such processes harmed human beings, or for that matter any sentient beings? Consider that the meteorite that ended the dinosaurs was very bad for them, but without those animals disappearing from the face of the earth we likely would not have evolved. The universe God needed, where an animal capable of perceiving value and freely choosing to instantiate it, who evolved through purposeless physical mechanism, could not function if the same mechanism that gave rise to that animal could not, sometimes, also destroy it. The “accidents of time” are not as such evil. An earthquake that kills people is no more evil than an earthquake that doesn’t, either because people have learned to mitigate its effects (earthquake-proof buildings) or because no people happened to live where it occurs. Either way, it is just an earthquake. Remember also that there are other aspects to this theology, personal-survival of death (see “What is the Soul”), but lets move on.

Besides natural evil, human beings also cause harm to other sentient beings, humans included. Philosophers call all of this evil, but they fail of a crucial distinction here. Humans cause harm in two ways. One is by making mistakes. We make decisions and perform actions, both moral and amoral,  that cause harm to others because we do not have a full understanding of the future consequences of our actions. It is not our intent that these actions subsequently cause harm, but they do. Mistakes are not evil, they are just errors.

But there is another category. Human beings can deliberately and freely choose to do that which they know is a mistake, to do deliberately something that is antithetical to the values. These actions are true evil. It is through error, deliberately and knowingly chosen, that evil enters the world. It is for this reason that free will is so intimately related to both the building-in-partnership-with-God the best possible universe, and to the degradation of any progress made in that direction, by the willful choice to contravene it. That choice is evil.

My view has been criticized on the grounds that “death is death” whether from earthquake, some error, or evil. This of course is true, but not to the point. Theology coheres together as a piece or not at all. Death from any source is temporary (see above link on the soul). What is important about the difference is that with evil human will is being freely (willfully) deployed in opposition to the direction of value compass. Because free will is so deployed there are consequences in addition to whatever might have stemmed from the action had it been purely a mistake.

Besides those impinging, psychologically and spiritually, on the person who commits evil, the consequences of evil are sociological. They impinge on human life in ways that error alone does not. They are, for example recursively reinforcing (one evil act leads to others by the same agent and others) where error is recursively-correcting. Agents, including the agent committing the error, tend to work toward mitigating the negative effects of a mistake once they are known. Errors serve to teach. Evil can also serve to teach, but typically those who commit it resist such teaching and it is left to others, using their free will, to mitigate its effects.

To make the [future] “best possible universe” God juxtaposed free will and purposeless mechanism in a physical universe capable of evolving value-discriminating mind. He could not do this without allowing that sometimes the physical mechanisms destroy the very minds (and bodies) that evolve from them. In the same way, he had to allow that free will might, if it was really free, be deployed in direct opposition to the universe plan.

The plan must eventually come to pass and be completed. That means the consequences of evil can only be temporary albeit from our viewpoint can extend in time over multiple human generations; all a blink-in-the-eye from God’s viewpoint. As concerns our agency, God must permit much more than he himself wills if free will is to be genuinely free.

Physics and the Evidence for Non-Material Consciousness

selfie

There is an old story of the net and the fishermen. A net having a weave that lets any object smaller than 10 inches long slip through it. Fishermen cast the net in the lake and harvest fish always ten inches long or longer. The fishermen mistakenly conclude that there are no fish in the lake smaller than 10 inches. Philosophy 101 students easily recognize the fishermen’s mistake. If there were fish in the lake smaller than 10 inches they would slip through the net.

Now imagine that there is some constraint on these fishermen that prevents them from weaving nets any more finely than they have. Is there any other means by which they might acquire evidence of fish smaller than ten inches long? As it happens there is. They can take some of the larger fish, keep them alive in captivity, and mate them. If successful, they would see that fish lay eggs, eggs hatch into little fish, and little fish, properly fed, grow into fish ten or more inches long! Having done this sort of thing many times, our fishermen can correctly induct, from many particular observations, that there are indeed fish in the lake smaller than ten inches because those smaller fish are the descendants of the bigger fish and one day will become bigger fish themselves.

Although the analogy is imperfect, physics, that is the present state of our body of science, has something in common with that net. Our senses and all the instruments and physics we can derive from them are physical. No matter how refined we make our instruments they are physical things and cannot measure or detect anything that isn’t also a physical thing. Quantum mechanics doesn’t help here. Ruth Kastner (“The Transactional Interpretation of Quantum Mechanics”) goes so far as to conclude that the solution to various quantum puzzles is to locate quantum phenomena outside of spacetime. But they remain very much physical nevertheless. As indeterminate quantum phenomena emerge into spacetime they become deterministic, fully participating in the time-bound causal web, subject to causal closure.

No one, even died-in-the-wool physicalists, deny that there is any logical proof of the absence of anything real that isn’t physical, but nevertheless most commit themselves to the proposition that no non-physical entity can be real based on the capacity of physics to be self-explanatory. There are also those who simply define ‘reality’ in such a way as to preclude anything that isn’t physical from being real, and therefore chalk up anything historically adduced for such reality to utter illusion, a mirage.

As with the problem of the net, we ask if there is any possible evidence for there being something real in the universe that isn’t physical? Unlike with the fish, we cannot merely encompass some part of the physical and watch it to see if it produces something non-physical. We can try of course. Experiments and observations have been going on since Newton, some would say since Galileo, without such a transformation ever being witnessed. Scientists and philosophers have long conceded that the non-physical, should it exist, cannot in principle be detected and measured with physical instruments, the only kind we can build. They further concede that it is, technically, an inductive error to conclude there is nothing other than the physical in the universe based on this incapacity alone.

What warrants that further conclusion is the observation that physics is causally closed on itself. It is one thing to concede that we could not in principle measure anything non-physical. But when we measure that which is physical, we discover that these measurements alone fulfill all explanatory requirements for the present state-of-the-universe. Physical causes and nothing but physical causes result in all the effects we can measure throughout the cosmos. Physical causes result only in physical effects and physical effects spring from nothing more than physical causes.

For my purposes, as with physics, ‘reality’ is associated with causal efficacy in the physical. Anything that is or can become a cause in the physical is real. Cause is to be taken to mean “contributing cause”. It need not be the sole cause, nor the physically proximate cause. To be a cause it is only required that some physical effect is the ultimate result. The causal closure hypothesis is related to the observation that physical effects have, at least, physical proximate causes. All measurable physical effects seem to have, immediate antecedents that are also physical. But this does not preclude the existence of non-physical causes. For a non-physical cause to be real, it is only necessary that an observer be able to connect up a purported cause and an effect measurable in the world. I will have more to say about this “connecting up”.

Among modern philosophers there are some (Chalmer’s, Nagel, Lowe, Haskers, Foster, O’Connor, and others) who push back on the physicalist claim. They argue that there is reason to believe that there is something both real and non-physical in the universe, specifically consciousness, that is a subjective through which we experience anything at all including our observation of the physical. Physicalists rejoin that this phenomenon, consciousness, is not a “non-material reality”. It is merely a way of viewing the material itself. A rain cloud looks very different from above and below, but both views are merely different perspectives of the same single thing. We confirm this assertion by tracing, physically, from the top to the bottom of the cloud and determine that it is the same entity viewed two different ways.

This does not appear to be possible as concerns consciousness. No physics has ever traced, physically, all the way from subjective experience to the physics (technically biology — brain states) that purportedly underlies it. Many (mostly scientists) argue that we just haven’t got there yet and we will someday make that tracing. Others, many more of them philosophers, argue that the physicalist rejoinder is more hubris than reality. That it might turn out impossible, in principle, to ever make that mapping. Of course this doesn’t mean brain states have nothing to do with consciousness for obviously they do. What it means is that consciousness is not (or may not be) merely “another view” of brain states.

I am not going to address those arguments here but I am going to explore the question whether or not this phenomenon we call consciousness is in fact evidence and in what way it is evidence for the existence of something real that is beyond the reach of physics because it is non-physical.

For any evidence to be evidence, the phenomenon for which it is adduced has to be real. There cannot be evidence for anything that is by definition unreal. At the same time any evidence, if it is evidence of anything at all, has to emerge from, or become available to, our subjective experience as observers. The evidence must appear in consciousness. From our own subjective points of view there is no evidence of anything in the universe, physical or otherwise, that doesn’t emerge in or through our experience — aided or unaided by instruments or quintessentially mental formalism like logic.

How do we fare here as concerns consciousness? Its reality is one of the matters in question. The independent reality of consciousness is controversial. We cannot demonstrate, physically, that it is real. On the other hand, as all evidence of any kind emerges through experience it seems strange to insist that our experience is nothing but illusion. What happens to the evidential status of physics itself if the consciousness that interprets physical evidence as such is only an illusion? Can evidence be real if the status of the “evidence interpreter” is not? What happens to the truth status of the proposition “physics is causally closed” if the subjective arena asserting that proposition is an illusion?

This threat to the veracity of physics is a real problem for physicalists who insist that consciousness cannot be real. It at least suggests that it might be real, that its reality cannot be ruled out by fiat and might have to be accepted for the sake of our seeming capacity to comprehend the world.

The evidence for the non-material character of consciousness also emerges in consciousness! An idea cannot be weighed but it nevertheless appears that ideas are instrumental in the process of moving our bodies and thus our capacity to control aspects of the world confirming the correspondence between experience and physics. All of human society, our technological infrastructure, political institutions, and history are a function of this relation between quintessentially non-material ideas and the physical world. Somewhere in the distant past lies an ancestor, a hunter-gatherer who carried a club and a piece of chipped flint. Having both of these objects and a knowledge of making rope or twine from plant stems, this ancestor thought to attempt tying the flint and the club together producing something novel and more utilitarian than either the flint or club alone. An idea became a physical thing, an ax, through the controlled (purposeful) movement of a body that tied the flint and club together.

Many of the actions we take appear, to experience, related to the ideas we have. Using our bodies, we can pattern the physical by mapping ideas onto it. This is what I spoke of above as a “connecting up”. That I use an idea, a mental picture perhaps of some intended physical end-product, along with appropriate motions of my body, to produce that end product. The connection between the idea and the end product is obvious and immediate to us. It is not a connection between the physical and something non-physical outside of ourselves (magic unicorns perhaps), but between ourselves (subjective experience), our bodies, and the final physical output. We understand that our physical hands fashioned the physical end-product and that our hands moved in response to physical nerve impulses. The connection backs up to what it was that set those nerve impulses in action; a non-physical idea coupled with a non-physical intent to attempt its implementation (a mapping) in the physical.

We take this relation so “for granted” that mostly we do not even notice it. The productive conjunction between ideas and objects, mediated by bodies, means that ideas are real. Through the mediating influence of the controlled body ideas are causally efficacious. This could not be so if ideas were nothing more than illusions. True ideas have correlative brain states that are physical, but we do not subjectively manipulate brain states. We juggle ideational contents of subjective consciousness directly and these have a quintessentially non-material character.

The non-material quality of ideas is not of course proven by their association with physical actions whose consequences are also manifest in consciousness. Deterministic brain states not manipulated in consciousness might result in both ideas (and all of consciousness) and movement thus explaining their apparent connection. If this were true however it would have to be true about every product of humanity from the first struck flint to the space station and for that matter all the institutions and historical contingencies resulting in the present state-of-the-world. A staggering set of deterministic coincidences for which we, that is subjective experience, can take no credit whatsoever.

One cannot have this both ways. Either the subjective arena has no causal efficacy whatsoever or there is here a genuine connection between non-material cause and physical effect. If we wish to suspend judgement on this dilemma we yet must acknowledge that subjective experience does at least rule out physicalist declarations of its impossibility. Our experience counts as enough evidence for the reality of the non-material to question the physicalist assertion that there cannot possibly be anything other than the physical in the universe. Subjective experience seems to be telling us that the non-material is real and the entire history of human civilization at least warrants our concession to the possibility.

The evidence suggests, if it does not formally demonstrate, that something real and non-material is possible and obtains inside the otherwise physical universe. Consciousness (broadly speaking) is that reality. All of the philosophers cited above are materialists but not physicalists. They share with the physicalists a conviction that everything inside the material universe, including consciousness, takes origin in nothing more than the physical. They break with the physicalists in asserting the non-physical can, in fact, emerge from the purely physical and that in this universe, consciousness is that non-physical emergent entity.

Once emerged, they assert, the non-material cannot be fully traced-back to the physical. Subjective experience is not merely another viewpoint, another way of “looking at” something physical, but a novel thing in itself. Once it comes to be, from out of the physical, it can no longer be fully reduced to the physical. This view is called “property dualism”. Two phenomenon, mind and physics, but ultimately a single source, physics. But this view has its own problem with the contents and qualities of experience. Even if the non-material cannot be reduced in any logical way to the physical (more or less the position of all the philosophers cited above) it must, nevertheless originate from nothing more than the physical and this means that some evidence of the transformation from physical to non-physical should lie in the physical past, in the history of the universe. That no such evidence has ever been observed is not proof that non-material origins are not purely physical.

To date no mechanism has been discovered in physics that would plausibly result in such a transformation. If it is true that no such mechanism exists, physics is really causally closed, then the emergence of the non-physical from the physical alone is not possible and no historical marks are there to be found!

Every one of these property dualist theories of the non-material amounts to presupposing either an opening in causal closure or an invisible (to physics) set of causal laws or properties in the physical that add the qualities (to physics) required to produce the non-material. The first approach implies some evidence of itself within physics as noted in the previous paragraph. None has been found, and none of our present theories of the world require any provision for it.

Metaphysically speaking, the second approach is no less supernatural than the hypothesis of a divine being. It may lack the being’s anthropomorphic qualities but its presence and interaction with the physical are no less inexplicable. The “coming to be” of these psycho-physical laws (Chalmers’ term) wants explaining, and their interaction with the physical is no less a mystery than the interaction problem posed by a substance-dualism of mind or for that matter God. For a more detailed treatment of this issue specifically see my “Fantasy Physics and the Genesis of Mind”

To wrap up I summarize what I hope I have accomplished.

1. Physics can measure only the physical.

2. Physics leaves in abeyance the question of some non-material reality inside the physical universe. It remains logically possible. Physics has no evidence for it, but all physics can assert with authority is that explanations of indisputably physical phenomena require no reference to it.

3. There are subjective observers inside the physical universe. These observers all have bodies made of matter and subject to measurement by physics. But they also have “subjective experience” whose qualities are not subject to physical measurement.

4. Either the qualities of subjective experience are not real or they are real and can make some contribution to physical cause; they can configure physical cause (movement of a body) to produce physical effects patterned by a non-material idea. The non-material idea can be mapped to physical reality or put conversely physical reality can be patterned, configured, by non-material ideas.

5. Either the whole of human history and achievement is a blind accident or non-material ideas are causally efficacious and therefore must be real.

In “An Epistemological Argument for Free Will” I argue that free will is real and our experience warrants that belief. None of what is discussed above impinges directly on free will. Our ideas might be both real and non-material without our having free will. The connection between ideas and the physical might, after all, be fully determined even if ideas are in fact the initial patterns of the physical result. But the subsequent free will argument does rest, metaphysically, on the reality and non-materiality of consciousness.
