Can I interchange the phrases 'it is rational to' and 'it makes sense to,' as I have been doing? It is primarily talk of what it "makes sense" to do, to feel, and to believe that concerns me here. Indeed for my purposes, I could drop talk of "rationality" altogether and speak only of its "making sense" to do and to feel certain things. I do claim, though, that the analysis I am giving fits important philosophical uses of the term 'rational.' It fits some and not others, and there are many uses of the term, both by philosophers and by nonphilosophers, that I am not trying to capture. I simply announce, then, that when I use the term 'rational' here, I am considering "it is rational" to do such and such as just another way of saying that it makes sense to do it-and likewise for emotions and beliefs.
