When I see two owls and then two more owls and conclude that I see four owls, I am responding to reasons, and it better not be my choice to believe that two plus two always equals four. If I am a rational person, I will have that belief by necessity, whether I wanted to or not. So it's not that strange to discuss responding to reasons out of necessity.
Nomy ArpalyI think it's ok to have wishes that conflict with each other - it's irrational to try to make them both come true, but not irrational simply to have them.
Nomy ArpalyI think that if your tenure case depends on your proving what you thought was a mathematical theorem and the proposed theorem turns out to be false just before your tenure decision, and you want to get tenure very badly, there is a sense in which it's perfectly understandable and reasonable of you to wish the proposed theorem were true and provable, even if it's logically impossible for it to be.
Nomy Arpaly"Externality" is a different phenomenon from akrasia and doesn't always come with it. The set of desires and actions from which one feels alienated isn't always the same as the set of desires and actions of which one disapproves. It has been pointed out that you can disapprove of something inside yourself but still experience it as yours ("damn it, here I go again!"). In addition, you can approve of something inside yourself but feel like it's not yours ("when the emergency sirens went off, it was as if someone calmer and more reasonable took over and knew just what to do").
Nomy ArpalyI don't think we are all irrational every time we fail to see through an argument in a book, but suppose it's true about you. You are still more rational than you think you are. You are irrational in a minor way - believing a misguided theory of the nature of rationality - but rational in a major way - you respond well to probabilistic evidence as you go through the day.
