Subjective Truth implies Free Will

"When you know the future perfectly, it's already passed." - Alan Watts

A corollary: Once you know what decision you will make, you have already made the decision.

Subjective Truth implies that if you don't know something, the state is undetermined, and "not knowing which universe you are in" is equivalent to the unknown states being undetermined in reality.

So under this context, making a decision is an act of discovering which universe you are in. For any unknown fact about your self, it is always possible to discover it eventually. As such, subjective truth alone implies free will.

And probably, objective truth implies determinism unless you do a bunch of complex mental acrobatics. But still, I *think* free will is compatible with determinism as long as you have a good definition of "self".

The more interesting question is why shouldn't this argument extend to not only the self, but to everything, to all that exists?

Now this is a deep one.

(Note on 2023-07-07: the argument seems wrong. But still definitely valuable as salvageable material)
