"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").

I am not committed in any way to the traditional concept of character - the concept of "character trait" as involving predictable behavior. I am committed to a view in the neighborhood - the view that the moral worth of one's actions depends on the quality of will expressed in them.

Suppose whether or not someone tells me a lie depends only on whether he wants to, but he is morally indifferent, he doesn't care much about the truth or about me, and his self interest, which he worships, tells him to lie, and so it comes about that given his psychology, it is a forgone conclusion that he will lie to me. I think in this case he is still blameworthy, and that implies, among other things, that he did something he ought not do.

I 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.

The fact that only humans above a certain age can be morally virtuous, rather than babies or cats, means that that being moral requires some cognitive ability. If virtue is about desires, it is worth remembering that you can't desire some things without being able to conceive of them. Suppose a virtuous person will desire to make people happy and desire to tell the truth. You can't desire to make people happy without having the concept "happy" and you can't desire to be truthful if you don't have have the concept "lie", so a cat or a baby cannot desire these things.

I 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.
