Nietzsche's On the Genealogy of Morality includes several cases of agents who are, prima facie, self-deceived. Recent work has linked these cases to deflationary accounts on the one hand and intentionalist Sartrean accounts on the other. But neither is fully satisfactory. I suggest a new account that gives a central role to focused daydreaming and imagination, especially as related to affective content that threatens to destabilize self-deception. This approach, not neatly categorizable, builds upon both deflationary and intentionalist accounts, emphasizing links (...) between vengefulness and forgiveness in Nietzsche's psychology. (shrink)
