I just happened to notice our gerbil-
cum-devil decided to criticize mechanical determinism. I thought about criticizing solipsistic idealism in response, but couldn't think how to make it both pointed and funny.
So instead, I'll try to draw some points from a project that's interested me for quite a while: meaningfully describing freedom of the will.
Both terms seem equally important here. It may be said, in a trivial sense, that any sapient and perhaps any sentient thing has will -- the capacity to effect a deliberate change in the world. It may equally be said that any sapient and perhaps sentient thing has a spectrum of possible ways in which they could change the world, of which only some are ruled out by obvious intractable constraints -- one cannot choose to fly, but one can deliberate over which of several foods one eats for breakfast.
If this is all that is meant by "free will," we're done. There is no point in arguing against this without very compelling evidence that it is in some way flawed, because it would fly so directly in the face of the experience apparently available to the vast majority of humans who have ever lived. This free will is, coincidentally, rather compatible with many descriptions of determinism. The set of options from which we are free to choose narrows, of course, but there is always some theoretical way in which it could be re-set. God could change Its mind, perhaps, or we could conceive of some way of altering the initial state of the universe (or creating our own in which the initial state was subtly altered).
But it seems to me to be a ridiculous straw-man of a position, both to attack "determinism" and to hold its own case. There is "free" and there is "will," but neither seems much to be a property of the other. The only link between them is this sense of deliberation... that is, that courses of action available to those
with will are not arrived at instantaneously, but must be figured, felt, computed, sniffed out. Options are weighed and cast aside until the course of action which actually is to be, or at least hoped to be (for no-one here either supposes omniscience as an aspect of the human condition), is arrived upon and enacted.
No, freedom of the will seems to me to suggest something much more profound than deliberation. It suggests, it seems to me, that that deliberative process is not one upon which, given identical factors down to the smallest each time, the same conclusion would in some possible worlds not be reached -- and yet neither is it said to be a randomness. For even a coin has "freedom," much in the sense I illustrated it above... there is more than one possible state it can conclude in... but I doubt anyone would suggest this is meaningfully the same as the "freedom" of the will.
But this is problematic to me. Deeply. Because another way of saying this is that there is a non-random
acausal element to deliberation. Or, in grandiose language, that we are each miniature First Causes.
This is voiciferously rejected by many proponents of free will, yet it must be if what I said above is an accurate depiction of the claim it makes... that is, that given absolutely identical sets of causes, in each case (and either ignoring random elements or assigning them the same state each time) there is a possible world in which another decision was reached after deliberation. For this to occur, there must be something intrinsic to the deliberative process which has
no prior cause -- or you must admit that you are a random creature who decides, not based on your knowledge, intuition, and feeling (all causes); but based on a game-spinner somewhere inside you that has perhaps a wide slice reading "eggs for breakfast" and a narrower, but just as existent slice reading "murder my neighbor's dog."
And yet, I see so few serious proponents of free will stepping forward to claim we are all gods, each one a Prime Mover.
Of course, there is nothing in the idea that decisions have random elements to contradict with the idea that there is no acausal element. This perhaps seems the most reasonable conclusion to take, given the evidence. It could, if one were in the mood for oxymoron, be called something like "chaotic determinism," or in a more classical mood "indeterminacy," although that may confuse some philosophers. Perhaps
tychism is as good a name as any, when it is convenient to refer to.
Einstein once paraphrased Schopenhauer in German, and it is the translation of that I find most relevant for this conversation: "Man can do as he wills, but cannot choose what he wills."
Or, convert me. Does freedom of the will mean something else? Or have you spied the way out of my dillemma, and wish to persuade me that the will does not contain the cause-less, per se, but actually not subject to causality as we understand it? The latter has been opined to me more than once, but it is still a position I do not claim to comprehend.
