 Before we ask whether this pessimism about the compatibility of free will with determinism is warranted, we should pause to ask whether there really is a substantive disagreement between compatibilists and incompatibilists. When an incompatibilist says that determinism would rob us of the free will we think we have, including genuine choices and the ability to do otherwise, and when the compatibilist denies this, are they asserting and denying the same proposition? Or is the incompatibilist asserting one thing while the compatibilist is denying something else?
