I argue that there cannot be a sense attached to “could have done otherwise” that is both compatible with the truth of determinism and relevant to the question of free will. Then I develop an incompatibilist response to the common objection that the incompatibilist requires of free actions that they have no causes and therefore cannot be anything for which an agent can be responsible. In the process, I bring out a similarity between compatibilism and incompatibilism in respect of where (...) their problem lies. (shrink)

Many philosophers appeal to intuitions to support some philosophical views. However, there is reason to be concerned about this practice as scientific evidence has documented systematic bias in philosophically relevant intuitions as a function of seemingly irrelevant features (e.g., personality). One popular defense used to insulate philosophers from these concerns holds that philosophical expertise eliminates the influence of these extraneous factors. Here, we test this assumption. We present data suggesting that verifiable philosophical expertise in the free will debate-as measured by (...) a reliable and validated test of expert knowledge-does not eliminate the influence of one important extraneous feature (i.e., the heritable personality trait extraversion) on judgments concerning freedom and moral responsibility. These results suggest that, in at least some important cases, the expertise defense fails. Implications for the practice of philosophy, experimental philosophy, and applied ethics are discussed.
