Where do moral values come from? Not whether they are true — Nietzsche does not ask that. He asks who made them, and what they wanted.
On the Genealogy of Morals is a polemic. Nietzsche says so on the title page, and he means it. Written in the summer of 1887 to sharpen what Beyond Good and Evil had stated obliquely, it asks a single deceptively flat question: where do our moral values actually come from? Not whether they are true. Not whether they are good. Where they came from, who made them, and what those makers wanted.
The first essay tells the story of the slave revolt in morality — how "good" once meant noble and powerful, and was inverted by ressentiment into a weapon against the strong. The second traces guilt back through the creditor-debtor relation in archaic law to the "bad conscience": cruelty turned inward when it could no longer find an outward target. The third asks what ascetic ideals mean, and answers: a will that would rather negate itself than not will at all. Together, the three essays do not merely critique European morality; they locate the interested parties behind it — above all, the priest — and ask whether the human animal can yet be released into something braver than guilt.

The slave revolt in morality
The central historical claim of Essay 1: the moral vocabulary we have inherited is not the original one. "Good" once meant noble, powerful, self-affirming. The slave revolt inverted the table — and Nietzsche thinks it conquered Rome.
Ressentiment as the engine of moral inversion
Ressentiment is kept in French because no other word carries the same charge. It is not anger — anger discharges itself. Ressentiment is what anger becomes when it cannot discharge: stored, festering, finally creative.
Guilt as internalized cruelty: the bad conscience
Essay 2 opens with the breeding of an animal that can make promises. Its answer to how: pain. From the creditor-debtor relation comes the whole architecture of guilt. From enclosed society comes cruelty turned inward.
The ascetic ideal as the will turned against itself
Essay 3 is the longest and strangest. It asks what ascetic ideals mean for the artist, the philosopher, the priest, and modern humanity. The answer: a will so bereft of direction that it wills its own negation rather than cease willing.
The priest as the great valuator
Across all three essays one figure recurs: the priestly type. Not a particular religion — a psychological-historical role. The human being whose will to power runs through the manipulation of values, not through arms.
