There is free will.
Not if time has already happened; future, present, and past.
Genetics and environment at the very least places the outer boundaries on what we can become or choose to be. Whether or not we can actually self-determine within some range of options is something that would be difficult to prove. I think it might just appear that way because the human mind is complex to the point that we can't account for every cause and effect relationship that produces behavior.
The mindset that humans are separate from animals is an assumption that supports the idea of freewill, but that assumption seems a bit unfounded. My leaning is to see humans and animals as deterministic systems with levels of complexity that make some choices either appear random or willed by self.
If this is the case, it can imply greater hope for people because it implies that the problems of violence have a solution. If "evil" is not supernatural, or solely in the control of individual free-will, then that means that if the input is corrected, the output will be corrected. Correct poverty and desperation, understand mental illness and genetics, and there is a way to correct excessively destructive behaviors that increase suffering for all.
Ah, but how do you know that it has? And if it hasn't as of yet, how do you know that we have the free will to set the tone for when it does repeat? And if it has, does that mean at one point we did have free will?
It would seem that the human mind inherently negates free will. Free will cannot exist in a world where every effect has an external cause, and yet the human mind can conceive external causes for its choices even where there may be none in reality outside of human consciousness. So it would seem if there is free will, we would be entirely unaware of it since our minds would inherently try to negate its existence the moment it came into contemplation.
What a violent blow it is to the ego to understand that our very humanity is the greatest inhibitor to our freedom.
External causes don't negate the existence of choice though.
The question is not whether or not there is choice, but whether or not their is choice free of external causes. The definition of freewill is "the power of making free choices unconstrained by external agencies." So external causes do negate the existence of free choice, and thus negate the existance of free will.
I believe that "free will" exists; but, it's just as predictable as anything else.
I believe the universe is deterministic through-and-through.
Hmm. No, I don't think so. Our very existence is constrained by factors that were not the direct outcome of individual choice--such as biology or socio-economic background-- that in turn constrain and influence our future development and resulting decisions. I think we do have some choices, but these are limited to some pre-existing sociological framework, and I would be very hesitant to call that "free will."
