Abstract

If rationality requires you to F, is that a reason for you to F? Does it even follow that you have a reason to F? The answer to the second question will be ‘yes’ if rationality consists in responding correctly to reasons, but it does not. Plausibly, we ought to have the faculty of rationality for instrumental reasons. But even if this is so, it does not follow that we have a reason to do any particular thing that rationality requires of us. We have no grounds for answering ‘yes’ to either question.
