How moral values acquire a history › Can the history of a value change its authority?

Imagine someone who calls another person's success corrupt while describing their own exclusion as proof of integrity. Perhaps the criticism identifies a real injustice. Perhaps it also makes disappointment easier to bear. Both possibilities require examination. Discovering a motive behind the judgment would not, by itself, settle whether the judgment is right.

On the Genealogy of Morals investigates that difficult relationship between the origins of an evaluation and its authority. Nietzsche asks how concepts such as good, evil, guilt, and conscience acquired their meanings. He also asks what these values do to the people who live by them. The historical question is meant to disturb a confidence: that morality's familiar judgments deserve acceptance without an inquiry into their value.

His answers are polemical and often morally troubling. He attributes a creative role to resentment, connects responsibility with coercion, and interprets some forms of self-denial as ways of preserving a suffering life. Understanding those arguments requires distinguishing Nietzsche's hypotheses from established history, and his criticism of a value from the reasons we might still have to defend it.
