I already gave an example of how I can freely make a decision
(picking up a glass to drink from it).
It is an illusion that you "freely" make that decision.
What would "freely" mean? Suppose I gave you a free will test: I will say "Go!" in ten seconds, and at that point you either pick up a glass, or DON'T pick up a glass--your free choice.
First, it IS possible for you to make a perfectly random choice. You might, say, create the algorithm: I will look to my left, and if there's a green object in my field of view, I will pick up the glass, and I won't pick it up if there's no green object. If you really don't know what you will see, then the outcome will be "random."
OTHERWISE, your mind has certain specific, definable contents (if it EXISTS, it must be "one thing" and not "another thing." It's contents can be specified--if you have the means, of course). Those contents will work on "deciding" what you will do. To say the decision is "free" (in the way people TRULY MEAN by free will) is to assume that you can get OUT OF the physical nature of your brain and its contents, and then somehow "independently" (and I don't really even know what that MEANS, again, because the concept is based on an ILLUSION) "decide" whether to lift the glass or not.
It's not a free choice. If we could know the exact state of your mind and any relevant external stimuli in the ten seconds before "Go!" was announced, and the FORM of your mind, etc., then the outcome would be perfectly DETERMINANT--there is no "choice," there's only the illusion there's a choice.
AH! But you say "Oh yeah, if that's true then you could TELL ME which choice I"ll make! And then, dammit, I KNOW I could do the opposite." That's right, you could. I thought about this a long time ago, in thinking about free will. The fact is, that you can make the advance determination to "do the opposite of anything said." But that ain't "free will" it's just "contrariness." So you would go back to the original setup: would you DO what the prediction said, or do the opposite? And again, the result would depend on the CONTENTS OF YOUR BRAIN, and the deterministic processes that occurred during the ten second span. What else could it POSSIBLY depend on?
but I can still freely make my own decisions within space-time, no one/thing is stopping me.
Something like that would better be called "individual will." Yes, you can impose your own PERSONAL stuff (personality, what you had for breakfast, etc., etc.) to come up with a response that is YOURS. But, it's YOURS because it is derived uniquely from your brain, but that derivation is DETERMINED by the contents of your brain and brain state, etc. It's not a "free" choice, it's just "your" choice.
