Hi.
Where did I say anything about absolute free will? That is a seprate discussion, if you wish. Further, I did not find you pointing out the 'oversimplification' in my argument too.
I know. I was drawing outlandish conclusions on purpose. It's a cheap ploy, I will admit that.
If consciousness is a deterministic product of interaction of inert chemicals then there is no way that the truth value of a proposition can be determined objectively.
When one ascribes one's intelligence to blind chemical reactions in brain, one must not claim to know better than others.
I think you can know truth values independently, but not that many. Most of it
is culturally mediated conjecture.
There are physical interactions with the world that can be described logically, and independently repeated.
If we agree on a purely logical system to describe it, then those few things are known. That logical system is mathematics, and the descriptions that it can provide, tell us about he objective reality around us they we can share.
Our ability to make reliable predictions about this phenomena is what makes
me a materialist and a naturalist.
Some believe that the sum total of every experiential phenomena can be described mathematically, but we do not yet have the data or the technology yet to do so. I am among those who believe it can all be mathematically described, but not along those that suggest it can all be mathematically predicted.
In other words, we can eventually describe the effects of free will, but not make predictions, as free will produces new constants that change the outcomes.
