The Free Will Problem

Freedom and Foreknowledge

P1: If God is omniscient, then God knew before I was even born that I was going to do X at time T.

P2: If God cannot be wrong, then I cannot refrain from doing X at T.

P3: But if I cannot refrain from doing X at T, then I cannot do X at T freely.

C: So if God is omniscient, then I cannot act freely.

Naturalistic Free Will Dilemma

P1: Every action is either causally determined by prior events and the laws of nature or it is indeterminate.

P2: If S’s action A is causally determined by prior events and the laws of nature, then S could not have done other than A.

P3: If S’s action is indeterminate, then S could not have done other than A.

C1: So S could not have done other than A.

P4: S’s action A is free only if S could have done otherwise.

C2: S’s action A is not free.
