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

Characters in Hollywood movies encounter a lot of car chases. Characters in novels rarely wash their hands or do their laundry. And in the work of moral psychologists, people deliberate and reflect a lot. They deliberate, one sometimes feels, whenever they perform an action, and certainly whenever they act for good reasons.

"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").

Sometimes I suspect that there are two prototypes of philosophers who write about humans - I call them "celestials" and "terrestrials", without implying that celestials have their heads in the clouds or that terrestrials have theirs buried in the ground. The difference between these two types is not so much in their theories but in whether or not they would find it a very sad thing if it turned out that the only way a human is superior to a wolf is this: the human brain is significantly more capacious and complex.

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".

Other things being equal, ill will is worse than moral indifference (as in causing suffering for money vs causing suffering to cause suffering), though things are rarely equal.

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.
