And yes with reference to the first paragraph, "deciding whether an outcome is favourable or not" is something important I missed. It boils down to comparing outcomes to moral standards. These moral standards are either hereditary/socially-conditioned (both of which don't differ from computers with preprogrammed standards) or self-chosen morality - upon where the point hinges. I would put self-chosen moral standards down to fitting in with other standards upheld (merely a calculation), or driven by emotions - which are in essence further preprogramming (a controversial subject, given how damaging to the ego such an admission would be to many people who hold them dear) That's quite a crude compression of a long argument I admit!
Hi TrisB! You wrote: "To not have free will wouldn't stop you from making choices." Okay. But what kind of choices? You say computers can "learn." I accept that, with the qualification that they can only "learn" within the parameters established for them by their programmers: recursive loops, etc., etc., which perhaps provide for feedback that program logic can utilize in a "novel" way. Is this what you mean by "free will?"
But what a computer can never do is say, "I think I'll take a little break from executing this program, and go write a sonnet instead; or play baseball with my buddies; or maybe paint a watercolor, or compose a symphony, or build a tree house for my kids...." In that sense, computers are "determined," not free: They seemingly are "slaves" to their programs (and programmers) in a way a human being is not.
You wrote: I'm struggling in retrospect of my young days when I did believe in free will, and now trying desperately to understand what it could possibly be, and what would permit it to exist outside of order and chaos.
Well I certaintly agree with you that "order" tends very quickly to be boring, and that chaos produces "no occurrence [of] any significance."
When you boil it all down, human beings (and computers) are neither "orderly" nor "chaotic" (as a rule). The chief difference between them, it seems to me, is that humans can work outside of their "programs" -- which is why they have free will, and why computers do not. FWIW.
Being an atheist, you have ruled out a possible answer to the question of "what it could possibly be" in advance.
Thanks so much for writing, TrisB!
If you can, apply this analogy to the nature of dimensional complexities in space, time, soul of life force, and spirit, such that a being of merely space, time, soulish level of complexity is a reactive-to-only-stimuli sensed by the three dimensional existence, while the space,time, soulish, spirit being has another level of variability to which decisions may be submitted for review before reaction. A cat killing a mouse is not committing a good or bad act, but a human killing another innocent human (not in self-defense or in war, for example) is committing a bad deed by the reckoning of a dimensional variability (spirit) not available to the cat or the mouse.
Imagine that the Creator God is seven dimensional (space, time, soul, spirit, 5, 6, and 7, though in my limits I cannot fathom what to name the 5th, 6th, or 7th dimensions of The Creator God's variability). While the cat is free to kill or not to kill the mouse, based upon abilities, the human is more free and more responsible to utilize the greater variability factors of his or her existent reality.
If you can imagine each dimension has three variable expressions (as in space has length, width, and height; time has past, present, future; soul has will, emotion, mind; spirit has ... well, you get the idea), the human is not just one level more free, but three levels/exponentials more free than the cat or mouse, having a spirit component the cat and mouse do not have.
The above is merely offered as a means to open thought to more realistic discussion not limited by antiquated notions of 'all animal kingdom species are the same in moral value'. Consider the entire field of variables is essential in reaching an ultimate truth regarding the reality of the variables, but we haven't the means to define all the variables yet, so we cannot 'know' in a scientific sense that there is no God of Creation ... to assume there is no God of Creation is arrogant in the main, since taking such a perspective assumes personal abilities regarding the variables not yet well defined. It is not however arrogant to postulate variabilities we do not have (yet; we are an evolving species) and assign these greater variabilities to God of Creation, an uncaused cause of our reality. Is it irrational to postulate God of seven dimensions and believe our universe (the realm of our perceptions, and don't eliminate spirit as a means of some perception) exists within those seven yet the One Of All Seven is outside and inside our realm? Philip got that same Physics lesson from Jesus as related in John's Gospel, 14th Chapter. You might find it an interesting read.
