IB Philosophy 10.5 on the Genealogy of Morality – Friedrich Nietzsche Key Definitions

Nietzsche's term for the systematic valuation of self-denial, suffering, and the renunciation of earthly life, expressed in religious, philosophical, and moral traditions that treat the body and its drives as obstacles to higher truth or goodness. He argues in the Third Essay of the Genealogy that the ascetic ideal paradoxically represents the will to power in disguise: the ascetic still imposes meaning on suffering and exercises control over existence, but does so by denying life rather than affirming it.

Nietzsche's term for the condition that arises when human beings' natural aggressive instincts, blocked from outward expression by the demands of social life, are turned inward against the self, producing a painful inner world of self-punishment, guilt, and moral self-scrutiny. Nietzsche regards bad conscience as a psychological illness but also as the origin of human creativity, imagination, and depth of soul.

Immanuel Kant's categorical imperative is the supreme principle of morality, commanding unconditionally. Its first formulation requires acting only on maxims that could be willed as universal laws, and its second formulation requires treating persons always as ends in themselves, never merely as means.

In Nietzsche's genealogy of morality, the creditor-debtor relationship is the foundational economic relationship from which moral guilt evolved. When a debtor could not repay a material debt, the creditor was entitled to inflict physical suffering as compensation, on the logic that the creditor's pleasure in the debtor's pain served as an equivalent exchange.

The genealogical method is Nietzsche's approach to understanding moral concepts by tracing their historical and psychological origins rather than evaluating them as timeless truths, asking how a value emerged, what human needs it serves, and whose interests it advances.

in Nietzsche's usage, a method of philosophical inquiry that traces the historical and psychological origins of moral concepts, revealing that values presented as eternal or natural are in fact products of specific human needs, power relations, and cultural conditions. Genealogy asks not 'what is good?' but 'under what conditions did human beings devise these value judgments?', exposing the hidden interests and drives behind moral systems.

For Nietzsche, herd mentality is the characteristic disposition of the masses who value comfort, security, and mediocrity above all else, elevating values suited to the weak and conformist while suppressing individual drives toward excellence and self-overcoming.

Nietzsche's account of the internalization of instincts describes what happens when human beings' natural aggressive drives, which could once be discharged outwardly, are blocked by the constraints of social life and redirected against the self. This turning of instincts inward produces the "inner world" of conscience, self-punishment, and moral self-scrutiny.

In Nietzsche's account, master morality is a value system originating with the strong and noble, in which 'good' means noble, powerful, and life-affirming, and 'bad' simply means common, low, or weak. The noble type creates values spontaneously from a sense of fullness and self-affirmation, without reference to or reaction against others.

Moral anti-realism is the metaethical view that there are no objective moral facts independent of human minds, cultures, or power relations. Anti-realist positions include emotivism (moral statements express attitudes rather than facts) and error theory (all positive moral claims are false because no moral facts exist).

Moral values: standards or principles concerning what is right, wrong, good, or bad that carry a sense of obligation or authority; meta-ethics asks whether moral values are natural or cultural, universal or relative, subjective or objective.

In Nietzsche's philosophy, pathos of distance refers to the noble type's profound felt sense of being fundamentally and qualitatively different from those of lower rank. It is not petty arrogance but a deep, creative self-assurance from which the noble type spontaneously generates its own values.

Nietzsche's perspectivism holds that all knowledge and value judgments arise from a particular perspective, shaped by the interests, drives, and circumstances of the knower, with no neutral 'view from nowhere' from which to evaluate claims absolutely. This does not collapse into relativism, since Nietzsche still distinguishes between life-affirming and life-denying perspectives.

The power-knowledge nexus, a concept developed by Michel Foucault building on Nietzsche, holds that power and knowledge are not separate domains but mutually constitutive. Those who hold power determine what counts as legitimate knowledge, and those who control knowledge gain power over how people understand themselves and their world.

a French term Nietzsche uses to describe a specific psychological condition of suppressed resentment, envy, and hostility toward those perceived as stronger or more powerful. In his genealogy, ressentiment is the emotional origin of slave morality: the weak invert the values of the strong, redefining their own weakness as virtue and the strength of others as evil.

Nietzsche's revaluation of values (German: Umwerthung aller Werthe) is the project of critically reassessing every inherited moral assumption rather than accepting them on faith. It does not propose a new fixed moral code but calls for a new relationship to value creation, one that becomes urgent once genealogical analysis has exposed that dominant moral systems grew from ressentiment and the ascetic ideal rather than from genuine life-affirmation.

Schuld is the German word meaning both "guilt" and "debt," which Nietzsche uses as evidence that moral guilt originated in the economic relationship between creditor and debtor rather than in reason or divine command. This linguistic overlap reveals that the moral sense of owing something for wrongdoing evolved from the pre-moral sense of owing a material repayment.

In Nietzsche's philosophy, self-overcoming (German: Selbstüberwindung) is the highest expression of the will to power, understood not as domination over others but as disciplined mastery over oneself. It involves continually surpassing previous limits and redirecting drives into artistic creation, intellectual achievement, and personal excellence rather than inward as guilt.

Nietzsche's concept of the fundamental drive underlying all human behavior and valuation, not merely a desire for political domination, but a striving to express, expand, and impose one's form upon the world. In the context of the genealogical method, the will to power explains why moral systems are created and enforced: every moral code reflects the drive of a particular group to have its values recognized as authoritative and universal.

Nietzsche's concept of the will to truth identifies the unconditional drive to seek objective truth as itself a value choice grounded in asceticism rather than a neutral rational impulse, challenging us to ask whether this commitment might be a disguised form of life-denial.
