The minimal free will thesis (MFT) holds that at least some of the time, someone has more than one course of action that he can perform.

1. With respect to the free-will issue, we should refrain from believing falsehoods. (premise)
2. Whatever should be done can be done. (premise)
3. If determinism is true, then whatever can be done, is done. (premise)
4. I believe MFT. (premise)
5. With respect to the free-will issue, we can refrain from believing falsehoods. (from 1,2)
6. If determinism is true, then with respect to the free will issue, we refrain from believing falsehoods. (from 3,5)
7. If determinism is true, then MFT is true. (from 6,4)
8. MFT is true. (from 7)
The validity of steps 5-8 should be uncontroversial.(3) In step 7, we see that, if determinism is true, then MFT is not a falsehood, since if it were, we would (step 6) refrain from believing it, whereas some in fact believe it (step 4). Thus, we see that determinism is self-refuting, in the sense that, modulo certain true premises, determinism implies its own contradictory (MFT). Any proposition that thus implies its own contradictory is false, so determinism is false, and MFT true.
