P1: if something is determined then it can not do other than it must.
P2: systems built from determined interactions are themselves determined.
P3: the mind and will are systems built from determined interactions.
Conclusion: the mind and will can not do other than they must.
Is this valid?
Are any of the premises disputed?
If it is valid, and the premises not disputed, where is the freedom, other than in veiled illusion only, masking the determined nature of our actions?
Acts of will are generally thought to be intentional actions. They aren't just random tosses of the dice. So it would be false to imagine human action as being unrelated to anything else. Obviously it's closely associated with our purposes, our understanding of the situation we are in, our knowledge base, our emotional state, and all kinds of things like that.
That's basically what "free-will" means, most of the time the phrase is used. It means that our acts of will, our choices and decisions, are the result of our own intentions, not somebody else's. The choices we reach weren't imposed on us coercively by some outside force. They arose in our own minds, out of our own understanding and desires.
If we assume a physicalist stance (as I do) and if we basically reduce our psychologistic concepts to events occuring in the underlying neurophysiology (as I'm inclined to try to do), then the idea of acts of will arising from our prexisting intentions, desires and understanding may all receive causal interpretations, without doing any real damage to the free-will idea. We aren't denying that our own knowledge and intentions shape the decision processes that arise from them, we are just giving a causal account of how that happens.
It doesn't even mean that some modest determinism is inconsistent with our intuitions of free-will. Our wills do seem to be determined to some large extent by our desires and by our understanding of the situations we find ourselves in. Nobody needs to deny that, and probably shouldn't if we want to make sense of human behavior. And our internal states, and the external states that surround us, don't arise from nowhere.
What I'm suggesting is that the free-will intuition isn't really inconsistent with causality and even with determinism, provided that they remain temporally local, restricted to short time scales. Everyone agrees that free actions arise from the actor's own understanding, intentions and will. Our understanding and intentions are in turn shaped by our previous life histories.
What does seem to do violence to the free-will intuition is the strong-determinististic speculation that all of this stuff was already fully predetermined in all of its specifics long before any of it happens. The state of the universe at time A fully determines the state of the universe all the way out to time Z, such that any idea we might have that a particular organisms' own internal real-time cognitive processes are what's guiding the organism's behavior is merely an illusion. Everything it does was all fated to happen precisely that way at the very beginning of time. That's where any (presumably divine) free choice that might have occurred was actually made, back at creation, when the laws of physics were enacted and the universe's initial conditions specified. Everything else follows inexorably from that.
The idea of probabilistic causality seems to me like it might be a way to avoid that strong-deterministic conclusion, without denying causality and even determinism entirely. It allows us to continue saying that event A causes event B causes event C... Every event has a preceding cause. But event A might not totally determine event B, there might be some unpredictability in what happens. As the universe evolves and events proliferate, small indeterminacies multiply into big ones, eventually to the point where more temporally distant states of affairs can't be said to have been determined by early ones at all, even if continuous chains of probabilistic causation still link them. Event A simply doesn't permit us to accurately predict event Z. The universe's timeline might penetrate into possibility-space in a fundamentally unpredictable way. There will still be causal chains determining things, but for highly complex systems the temporal range of exact determinism might be relatively short, getting fuzzier as timescales expand.
So, if an organism in this less rigidly deterministic kind of ontological environment still wants to behave appropriately in whatever situation it finds itself in, pursuing food, avoiding predators, or making it through another day of work, it's own internal onboard data-processor, however neurophysiological, causal and even deterministic it might be, is still going to have to size up the surrounding situation in the light of the knowledge it's acquired, factor in its own goals and purposes, decide on and then initiate a course of action, making continuous mid-course corrections as events require. What's happening inside that organism's head still matters. It will still seem to possess what we think of as a will, will display volition and will essentially be steering itself.
That's what free-will means to me.
