[This approach] displays the characteristic philosophical lust to vanquish the skeptic by arguing him out of his skepticism, without appeal to moral and political considerations or to the facts of everyday life.

Since for me moral demands necessarily flow from human psychology, I don't think we can be obliged to do something that we are not motivated in any way to do. In other words, I'm an "internalist" about morality.
