  Moral psychology: Agency of the sort required for free will and moral responsibility appears to require mental causation. If your behavior is not caused by your mind’s activities—its deliberations, decisions, and the like—what sense would it make to hold you responsible for what your body does? You would appear to be scarcely more than a passive observer of your body’s activities. We would then need to abandon what Strawson (1962) calls our “reactive attitudes”, the moral attitudes and feelings (e.g., gratitude, resentment) so central to our interpersonal lives.
