Abraham Roth argues that to accept a promise is to intend the performance of the promised action. I argue that this proposal runs into trouble because it makes it hard to explain how promises provide reasons for the performance of the promised action.

I argue that this fix would implausibly shrink the class of binding promises (...) and suggest that similar difficulties may arise for any theory that casts promises as an exercise of shared agency.
