Abstract

A familiar complaint against the principle that “ought” implies “can” is that it seems that agents can intentionally make it the case that they cannot perform acts that they nonetheless ought to perform. I propose a related principle that I call the principle that “the thing to do” implies “can.” I argue that the principle that “the thing to do” implies “can” is implied by important but underappreciated truths about practical reason, and that it is not vulnerable to the familiar complaint against “ought” implies “can.” Moreover, I suggest that “the thing to do” implies “can” has interesting implications for “ought” implies “can” - implications that depend on the relation between claims about what we ought to do and claims about the thing to do.
