On Regretting Things I Didn't Do and Couldn't Have Done

One of the lines of investigation opened up by Wallace in The View from Here concerns the notion of regret: what it is, what it is rationally constrained by, and what are the proper objects of regret. A distinctive feature of Wallace's view is that regret is an intention-like state, which, whilst backward-looking, is bound up with our future directed practices of value. In this commentary, I set out Wallace's claims on regret, its rational constraints, and its objects, and raise some worries about Wallace's position on each of these three issues.
