Book: On the Genealogy of Morals

Overview
Friedrich Nietzsche’s 1887 book On the Genealogy of Morals examines the origins, development, and consequences of our moral values by tracing their historical and psychological roots. Rather than treating morality as timeless or self-evident, Nietzsche asks how concepts like good, evil, guilt, and conscience arose, who benefited from their emergence, and what drives sustain them. Across three essays, he contrasts aristocratic value-creation with the reactive moralities of the weak, explores how the internalization of instincts produces the “bad conscience,” and uncovers the ascetic ideal as the hidden motor of Western spirituality, philosophy, and even science. The inquiry serves a larger project: a revaluation of values that might clear space for more life-affirming modes of thought and culture.

First Essay: Good and Evil, Good and Bad
Nietzsche distinguishes between two moral vocabularies. In noble or master morality, “good” names the qualities of the strong, healthy, and self-affirming; “bad” designates what is common, weak, or low. This value scheme is spontaneous and creative, springing from plenitude. By contrast, slave morality arises from ressentiment, the corrosive, vengeful reaction of the powerless toward the powerful. Under priestly leadership, this ressentiment inverts values: the nobly “good” becomes “evil,” while the weak call themselves “good” in virtue of humility, patience, and pity. Nietzsche reads the triumph of this inversion, crystallized in Judeo-Christian morality, as a historical “slave revolt” in morality that universalizes a reactive ideal and levels distinctions of rank. Modern egalitarian and humanitarian ethics, he argues, largely carry this inheritance.

Second Essay: Guilt, Bad Conscience, and Punishment
The second essay seeks the genesis of guilt and the “bad conscience.” Nietzsche roots guilt not in a metaphysical offense but in the concrete creditor–debtor relation: early punishment sought repayment and mnemonic training, not moral blame. Pain functioned as a technology of memory, forging a “memory of the will” so that promises could be kept. With the rise of more stable communities and states, aggressive instincts that once discharged outward are turned inward; this repression generates the bad conscience, a self-cruelty in which the animal that cannot attack external enemies attacks itself. Later, under the ascetic priest, this psychological condition is moralized: guilt becomes offense against God, debt becomes infinite, and suffering is endowed with moral meaning. The priest channels ressentiment, managing the sick and resentful by giving their suffering a purpose while deepening their dependence.

Third Essay: The Meaning of Ascetic Ideals
The ascetic ideal, a will to self-denial and truth-at-any-cost, supplies meaning in a world shot through with suffering. Nietzsche shows how priests, philosophers, artists, and scientists all appropriate this ideal differently. Priests deploy it to exercise power over the sick; philosophers enlist it to guarantee objectivity and the purity of knowledge; scientists inherit its cold discipline and devotion to truth, even when that truth undermines life. The will to truth turns its blade against itself, producing nihilism when inherited values collapse and no new affirmations emerge. Nietzsche weighs art’s counterforce as a possible alternative source of affirmation and suggests the need for future value-creators who can sublimate drives without denying them, translating strength into new tables of value.

Method and Aim
Nietzsche’s genealogy combines philology, history, and psychological insight to expose the contingencies behind moral concepts, challenging “English psychologists” and utilitarians who derive morality from altruism or utility. He frames moral life through the dynamics of will to power, not as a simplistic doctrine of domination but as a plural, interpretive struggle of forces that create meanings. By stripping moral concepts of their innocence, he seeks to free readers from inherited guilt and reactive habits, preparing a space in which stronger, more affirmative evaluations might be dared.
