I must be missing the point: I don’t understand the need for an “assumption”. (I don’t like assumptions, generally speaking.) That we actually HAVE free will would seem to be sufficient. I fully understand that, “There is no room in a deterministic world for discovering the truth.” My point is that the empirical (in a sense) existence of free will in free agents is enough. No “assumptions” need be made.
The sentence above that has been bolded is confusing. It could have either of two meanings: 1.) it could mean “discover;” or, 2.) it could mean “determinate”, as in render “deterministic”.
I will attempt to make plain the point one final time.
In order for me to
discover whether I have free will, I must first treat the problem as if I do (as in order to discover truth, one must have free will), which makes the quest rather ridiculous. The truth cannot be obtained from any other standpoint, and so we have already made our conclusion on the subject out of necessity, in order to attack the problem. And this was done before the quest had even begun. Does that make sense?
This does not suggest that we definitely have free will, it suggests if we believe that the truth (or
any truth) can be obtained, then we have already concluded that we have free will. Why? Because the discovery of truth requires free will.
The reason that it doesn’t suggest we definitely have free will is that it IS a possibility that the truth *cannot * be obtained, that we live in a deterministic world. The question of free will directly results from the question of determinism.
Are we finally on the same page?
Why do you perceive a problem with the trustworthiness of our observations?
Of others?
It relies on more assumptions than (frankly) need to be made. Primarily, it relies on the idea that, if others do not have free will then I don’t either.
Keep in mind, I know less about others’ their nature and behaviour than my own, as well as the fact that I cannot know for sure which or how many of their characteristics can be applied to me.
These might seem trivial assumptions to you, but in the realm of philosophy they are quite significant. It is simply safer for me to limit my conclusion to be based solely on observations of myself.
