i don't believe in free will--only the illusion of free will. this isn't meant to be a proof of free will. but i think if you believe that einstein was right in searching for a unified theory, and that our universe is predictable, then free will can't be possible
Discussions on "free will" are notoriously difficult, usually because most participants take sides before they even agree what they are talking about (ie participants declare "I do/do not believe in free will" before there is any agreement on the definition or meaning of "free will").
Therefore, rather than debate whether "free will" (whatever the definition) really exists, I think it is much more instructive to ask :
what do people really mean when they say that they believe they act with "free will", and are they justified in having this belief?
I humbly suggest that what most people (who claim to believe in "free will") mean when they say they act with "free will" is that they believe their
actions are not entirely constrained by external factors
I say "entirely" constrained because I believe most of us would agree that our actions are usually some way constrained to a greater or lesser extent by external factors (eg I cannot willingly hold my breath for more than a minute or two, no matter how much I "want" to), but belief in "free will" would imply that not all of the external constraints on our actions are necessarily absolute.
This is where it becomes useful to look closely at how we define the "person" (or better still, the agent) which we are claiming has this "free will".
Paraphrasing Dennett, one can externalise everything by making oneself really, really small. Conversely, an agent can subsume many (potentially external) constraints within itself by making itself a sufficiently finite size.
What we call our "self" is not an infinitesimal point in space. It has finite physical and logical boundaries and, most importantly, it includes within those boundaries many of the causes and effects of our decisions; in fact the personal decision-making process is based on what I like to call
self-referential causal loops.
If we can identify the external "cause" of a particular decision (ie an external constraint on our free will) then we
know that we are not deciding freely. But for many of our decisions we are unable to unambiguously identify the "causes", simply because those causes are internalised in a complex and self-referential way within our decision-making selves.
Thus, it is
not the case that our "free will" decisions are uncaused; it is
not the case that our "free will" decisions are unconstrained. It is simply the case that the decisions that we choose to call "free will" decisions are caused and constrained largely by internal
self-referential causal loops, of which we have (most of the time) incomplete awareness - and this is what leads us to say that we act with "free will".
Some may call "free will" illusion. I do not. "Free will" is a very real feeling that we have, and when we understand precisely what it is in the way I have described above, then we can clearly see that "free will" is real and we are justified in believing that we act with "free will", even in a deterministic universe. "Free will" is not an illusion. But it is important to understand exactly what it is, and also what it is not.
