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.
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 here 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, 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. Human choice, the capacity of human free will to create new realities, novel orders on top of deterministic mechanism, is novel in itself, something that is not exhibited in the rest of the animal kingdom.
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-axe-weilding 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, the 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 is allowed (in God’s case restricts himself) only to suggest what we create and never dictate it!
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 wanted.
How can we begin to say what God wants? 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 his values which for now we know only as our dim detection of truth, beauty, and goodness. In theological circles this 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. 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”. Apparently, at least God apparently thinks so, the best possible universe emerges over time when human beings, of their own free will, choose purposes and create based on what they perceive to be alignment with the values! What God wants is that world that results from that choice when the choice is utterly free. 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 come about 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 of God’s will. Three things are traditionally taken to be values as such; 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. Phenomenologically, 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) forsees 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 through choosing to instantiate the values! They 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 respect to the choice to attempt some mapping 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, avere 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 megar 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 yeilding 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.
