Hey! This is my first post, and I find this particular topic very fascinating.
At this point, it seems you’re hung up on the definition of “free will.” Onenow1 offered that free will is “the ability to make a decision.” That’s a prerequisite for having free will, certainly, but not the essence of it.
The computer I’m typing on at this moment has the ability to make rational decisions, just as a human being does, yet no one would say that it has free will. Why is that? It’s because the computer’s decisions strictly follow from the programming and user-provided (name removed by moderator)ut, as effect follows cause. There is no free will for a computer because every decision can be predetermined if one knows the variables that go into making that decision.
So then, to have free will, any decision of the computer would have to be *indeterminate * until made. That is, even if you know every variable the computer is considering, and provided you know the decision algorithm used by the computer, you would still be unable to predict the decision the computer will make.
Therefore, assuming human beings with our large brains are merely biological, as opposed to silicon, computers, the definition of free will is as follows: To have “free will,” a person’s decisions must not be constrained by the usual principles of cause and effect that apply to nonhuman computers, such that no ordinary computer with complete knowledge of the human computer and its (name removed by moderator)uts, motives, environment, quirks, and decision-making processes will be able to predict the decisions the human computer will make. But what could give the decisions of a human mind the property of being indeterminate at all points in time prior to the decision being made? Well, one interpretation of quantum uncertainty holds that quantum systems are indeterminate until disturbed, so if we assume that quantum effects play a role in the brain and decision-making, it could be that this accounts for “free will.” That said, this would presumably reduce one’s decisions to a random probability distribution. Is “random will” equivalent to free will? Not really.
What then remains? Are human decisions caused–and thus constrained and unfree–or are they random? Neither solution amounts to free will as I would understand it. Seeing no other possibilities, I must conclude that humans do not possess free will. For that matter, neither would God himself, or Lucifer.
Suggesting that free will is a nonsensical construct uncomforts most people, because they imagine that no free will implies no moral culpability. I reject that notion, however, but such is a topic for another thread.
