Nietzsche: Genealogy and the Critique of Power (Aspect II: Historicity)
This text is a preview of History of the Reception of Hegel, volume I, to be published in 2026 by Reflexivity Press.
We encounter Nietzsche here a second time — not now as a critic of reason’s claim to precedence, but as a radicalizer of historicity. Both aspects are connected in Nietzsche’s thought, but they have had different effects on his reception.
Friedrich Nietzsche developed the most radical critique of rationality as such, and thereby also of Hegel’s logic. His critique was not only philosophical but methodologically revolutionary. The genealogical method posed the question of truth itself in a radically new way.[1]
Nietzsche’s genealogy is radical historicization. It does not ask, “What is truth?” but rather, “Where does our concept of truth come from? What constellations of power produced it? Whom does it serve?” Genealogy exposes all supposedly eternal truths as historical constructs.
“Good and evil” are not timeless categories but products of particular social constellations — the morality of masters versus the morality of slaves. “Truth” is not correspondence with reality but a useful fiction that has prevailed. “Reason” is not universal but the expression of specific forms of life.
Nietzsche’s differentiated understanding of Hegel already showed itself in On the Use and Abuse of History for Life (1874). He knew Hegel’s philosophy of history precisely and criticized it immanently, not from the outside. His diagnosis was precise: Hegel had made history into a tribunal before which everything that exists must justify itself. World history as the world’s court of judgment — but who sits in judgment? Reason itself. That is circular.[2]
The methodological innovation was developed in On the Genealogy of Morality (1887). Instead of asking “What follows logically from this concept?”, Nietzsche asked: “How did this concept arise? What interests stand behind it? Whom does this truth serve?” The genealogical method replaces logical derivation with historical reconstruction — but not as mere historiography, rather as the uncovering of hidden power structures.[3]
The new principle of genealogy was: origin before validity. The question of a concept’s origin is more important than the question of its logical justification. Not: “Is this concept true?” But: “How does this concept arise? What needs, drives, interests lead to its emergence? What power prevails when this concept counts as true?”[4]
The application to morality was exemplary. What we call “good” has its genealogy. The noble morality of ancient aristocracy called “good” whatever expressed one’s own will to life — strength, beauty, pride, power. The slave morality of Christianity inverted these values: “good” became what restrains the strong — humility, pity, equality, weakness. This revaluation was not a logical development but an act of revenge — the “slave revolt in morality.”[5]
The transfer to truth was even more radical. “Why truth?” This question calls the entire philosophical discourse into question. Philosophy from Plato to Hegel assumed that truth was the highest good — that it was worth striving for, that it was possible, that it was one. But why? Who profits from the will to truth? What structures of power are concealed behind the claim to objectivity?[6]
Perspectivism was the epistemological consequence. “There are no facts, only interpretations” — this famous formulation is usually misunderstood as relativistic subjectivism. But Nietzsche meant something else: every truth has its perspective. There is no knowledge without a standpoint, no objectivity without subjectivity, no truth without interest. This is not a renunciation of truth but insight into its situatedness.[7]
The analytics of power developed this further. The “will to power” is to be understood not only politically, but as the basic drive of all living things — including cognition. Thinking, too, is an expression of the will to power. Reason does not simply want to know — it wants to dominate, to order, to control. Logical categories are not neutral instruments but means of mastering the world.[8]
The specific critique of Hegel was: dialectic as sublimated domination. Hegel’s system claims to comprehend reality — but it takes possession of it. The absolute idea is the highest form of rationalization — everything becomes transparent, controllable, masterable. The contradictions that dialectic supposedly resolves are in truth the signs of life, which refuses to be forced into concepts. Sublation is subjugation.[9]
The radical consequence was the revaluation of all values. If reason itself is an expression of the will to power, then there are no neutral criteria of truth. Every morality, every logic, every science is an expression of particular interests of power. The task is not to find the true morality or the true logic, but to create new values — a “philosophy of the future” beyond good and evil, beyond true and false.[10]
The legitimate intuition is precise: the non-rational conditions of rationality are real. Thinking does not occur in a vacuum but is embedded in interests, needs, structures of power. The question “Whom does this truth serve?” is philosophically legitimate and necessary. The genealogical method explicates a new methodological principle that radicalizes the self-reflexivity of reason.[11]
The systematic limit, however, lies in the absolutization of genealogy. If everything is only interpretation, if all truth is only an expression of power, then this also applies to Nietzsche’s own genealogy. Then his critique, too, is only an expression of his will to power, his perspective, his interests. Radical perspectivism leads into a performative self-contradiction: the claim “There are only interpretations” is itself an interpretation, and at the same time claims to be more than an interpretation.[12]
The Hegel reconstruction developed here integrates Nietzsche’s legitimate insight without falling into his nihilistic consequence. Logic is not free of power — it arises in the enactment of practice permeated by power. The categories are not neutral — they express particular interests, legitimize particular orders, enable particular forms of domination. But this does not mean that all truth is only power. Reflection on the power structures of thought is itself a rational operation — it presupposes that we can distinguish between better and worse arguments.[13]
The ninth ethical criterion, which we derive from logic (but which is not explicit in Hegel), systematically integrates Nietzsche’s critique: self-reflexivity. A system must be able to apply itself to its own conditions — including the question of the power interests at work in its genesis. This self-application does not lead to the dissolution of all truth, but to awareness of one’s own limits.[14]
Nietzsche’s lasting achievement lies in the genealogical method and the analytics of power. His limit lies in the absolutization of perspective. An integration must show that the situatedness of knowledge does not mean its impossibility, but its condition. We always know from a standpoint — but different standpoints can correct one another mutually and lead to a more comprehensive truth.
