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 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.

A very tall man once asked a question after my talk. Before beginning his question, he explained that the reason he was standing up is not to be intimidating but rather to make eye contact. His question was essentially "are we really interested in moral motives? Isn't it all about action?". I pointed out to him that it was not enough for him to do the right thing - stand up - but he also wanted me to know that he is doing it from the right motive or for the right reason - to make eye contact, rather than to be intimidating. Voila, moral psychology.

I am an atheist. I don't think there's anything divine. Beautiful, impressive, awe-inspiring - sure, but not divine.

Though we think intrinsic desires tend to be pretty stable, we do not think they imply anything like the amount of predictability in behavior that traditional virtue ethics requires for someone to have a one-word-in-English character trait such as "benevolence". Other things being equal, a person with more of a desire for other people's wellbeing will do more for other people's wellbeing, but things are almost never equal.

Duties concern things that are voluntary. I do think that if you have a moral duty to bring me back the book you borrowed, that implies, roughly, that your doing so depends on your wanting to do so: if you want to bring me the book, you will. This is not the case if you are stuck at some airport due to a snowstorm, far away from me. This, however, is not the same as "ought" implying a metaphysical "can".
