Nietzsche As Epicurean Ally - Key Terminology

Introduction: Nietzsche as an Ally Of Epicurus Across Two Thousand Years

Nietzsche made no secret of his admiration for Epicurus. He called him the most honest of the ancient philosophers. He wrote that “the awakening sciences have allied themselves point by point with the philosophy of Epicurus, but point by point rejected Christianity.” He declared, in The Antichrist, that “Epicurus would have won” the battle for the soul of Western civilization had Paul not arrived to change its course. He described Epicurus as one of the few ancient thinkers who had genuinely understood that this world, approached honestly and wisely, is sufficient for a good human life.

The reason for that admiration is clear once you see what Nietzsche himself was actually attacking. The traditions Nietzsche spent his career fighting — Platonism, Christianity, Kantian ethics, and the philosophical mainstream that runs through all three — are exactly the traditions that attacked and buried Epicurean philosophy for two thousand years. Nietzsche was fighting much the same enemies that Epicurus had fought in prior incarnations but with the advantage of two thousand years of additional evidence.

This article explores how supporters of Epicurean philosophy can identify and employ Nietzsche’s arguments for themselves. The goal is to show that many of Nietzsche’s most cutting and incisive philosophical formulations reflect exactly the problems that Epicurus himself identified and fought against. Where Epicurus showed that these traditions were wrong, Nietzsche went further and exposed the psychological and historical roots of these errors in dramatic and explosive fashion.

One difficulty must first be addressed. Nietzsche often wrapped his explosive diagnoses in sarcasm and irony. Nietzsche regularly took a phrase that sounds like a neutral description or even a compliment and used it as a label for something he was attacking. To read these terms at face value - such as reading “the agreement of the wise” as a genuine endorsement of philosophical consensus, has it exactly backwards. Rather than citing the “great philosophers with respect and praise, Nietzsche is saying that when the great philosophers all agreed with each other about the value of life, they were all wrong in the same way, and that their agreement proves shared error rather than shared wisdom.

The same pattern runs throughout Nietzsche’s written works. Nietzsche’s “last man” is not a neutral description of a human type — it is Nietzsche’s most contemptuous label for the comfortable mediocrity that has given up on genuine living. “Decadence” does not mean moral excess but its opposite: withdrawal from life, life-denial dressed as philosophy. “Pity” is not a virtue to be nurtured but, in Nietzsche’s formulation, “the praxis of nihilism.” “The true world” is not a genuine reality but a fiction that centuries of philosophers constructed to make material existence seem insufficient.

In each case, the key is to understand what Nietzsche is attacking, and expecting his readers to understand because his readers shared his perspective. This article takes a number of his most important phrases and shows how Nietzsche’s meaning connects to the Epicurean position. The result is a vocabulary that Epicureans can use directly — a set of sharp and exact labels for diagnosing the errors that both Epicurus and Nietzsche opposed, expressed with the force and specificity that only a long view history - to which Epicurus did not live long enough to see for himself - could provide.

Part One: Terms About Reality and the World

Hinterwelt (Beyond-World)

The most fundamental term in Nietzsche’s critical vocabulary, coined in Thus Spoke Zarathustra (“Backworldsmen,” Part One). A Hinterwelt is any posited reality that lies behind, beyond, or above the world of ordinary material experience — claimed to be more real than this world, more important, the only proper object of philosophical attention — while the actual sensory world is demoted to shadow, appearance, preparation, or illusion.

The term sounds like a neutral philosophical descriptor. It is a withering diagnosis. Nietzsche identified the Hinterwelt as the central philosophical error running from Socrates and Plato through Christianity through Kant and Schopenhauer — the same error in different vocabularies across twenty-four centuries. Plato’s Forms are a Hinterwelt. The Christian heaven is a Hinterwelt. Kant’s Ding-an-sich is a Hinterwelt. Schopenhauer’s Will is a Hinterwelt. Each generation of philosophers in this tradition revised the packaging while preserving the fundamental claim: this world is not enough, and what is truly real lies elsewhere.

The relevance to Epicurean physics is direct. Epicurus’s foundational claim — that the universe consists of material bodies moving through void, and that no supernatural realm lies behind or above the natural world — is the precise refusal of the Hinterwelt. Nietzsche recognized this, and it is why he kept returning to Epicurus as the primary ancient precedent for what he was himself attempting.

”The True World” (die wahre Welt)

From Twilight of the Idols (“How the ‘True World’ Finally Became a Fable”). Nietzsche always uses this phrase in quotation marks or with equivalent signals that he is naming a target, not endorsing it. What philosophers and theologians have called the “true world” — Plato’s world of eternal Forms, the Christian heaven, the Kantian noumenon — is not a discovery. It is a fiction constructed by minds unwilling or unable to accept that this world, as sensation and experience present it, is the only world.

Nietzsche traces the history of this fiction through six stages:

The true world is attainable for the sage, the pious, the virtuous. (Plato)
The true world is unattainable for now, but promised to the sage. (Christianity)
The true world is unattainable and unprovable, but as an idea it still obligates us. (Kant)
The true world — if unattainable and without power to obligate, why bother with it? (First doubts)
The true world — an idea that is no longer of any use. Abolished. (Positivism)
The true world abolished — what world remains? The apparent one? But no! With the true world we have abolished the apparent one. (Nietzsche’s conclusion)

The last step is the crucial one. Once the “true world” is recognized as fiction, the very category of “appearance” that was defined in contrast to it collapses. There is only the world. Not the “apparent” world (which was defined as appearance by contrast to an allegedly more real world), and not the “true” world (which was the fiction). Just the world — the world of sensation, change, genuine goods, and genuine harms. This is Epicurean physics restated in Nietzsche’s terms.

”The Apparent World” (die scheinbare Welt)

The flip side of the “true world.” If the “true world” is abolished, the “apparent world” — the world dismissed as mere appearance by Plato, Christianity, and their successors — ceases to be mere appearance. It is just the world. Nietzsche’s conclusion that both must be abolished together is the logical completion of a move Epicurus had already made from the start: refusing to treat the world of sensation as deficient reality.

Nietzsche’s formulation in Twilight of the Idols (“Reason in Philosophy,” §2): “The senses do not lie.” What the Platonic tradition calls the deceptiveness of the senses is not a property of sensation itself but of what reason adds to sensory reports — permanence, substance, “thingness” that the senses themselves do not deliver. “What we make of their testimony, that alone introduces lies.” This is almost word-for-word the Epicurean position on the Canon: all sensations are true; error enters in the judgment added to them.

Becoming (Werden) vs. Being (Sein)

Nietzsche consistently affirms the world of becoming — change, flux, growth, decay — over the Platonic and theological insistence that genuine reality must be being — eternal, unchanging, incorruptible. “The true world” in all its versions is a world of being. The actual world is a world of becoming.

The Platonic-Christian-Kantian tradition treated becoming as the symptom of ontological deficiency — only what is eternal is fully real. Nietzsche traced this to a grammatical habit: language forces subjects beneath predicates, things beneath processes, beings beneath events. We say “lightning flashes” as if there were a lightning-thing behind the flashing. There is only the flash.

Epicurean physics makes the same refusal from the other direction: the universe is atoms in constant motion, compounds constantly forming and dissolving. Nothing in Epicurean physics is eternally static. Change is the fundamental condition of everything, and the philosophy is designed to enable a good life within that condition, not in flight from it. The Epicurean analysis of truth and reality in our article Truth and Reality Does Not Require Being Eternally the Same covers this territory in depth.

Part Two: Terms About Human Valuation

The Last Man (der letzte Mensch)

Introduced in the Prologue of Thus Spoke Zarathustra. One of Nietzsche’s most contemptuous terms, though it sounds merely descriptive. The last man is not the temporally final human being but the type of human being who has abandoned all aspiration, all self-overcoming, all genuine engagement with what life requires, in favor of minimal comfort, minimal risk, and universal mediocrity.

The last man says: “We have invented happiness.” He blinks. Everything is made small. No one becomes rich or poor; both are too bothersome. No one rules or obeys; both are too bothersome. There is no longer any shepherd or any herd — everyone wants the same thing and everyone is equal: “Whoever feels differently goes voluntarily into the madhouse.”

The connection to Epicurean philosophy requires care. The last man is precisely the misreading of Epicurean pleasure that the hostile tradition has always promoted: the reduction of the Epicurean goal to comfortable mediocrity, the smallest available satisfaction, the “enough” of passive contentment. The article on The Half-Full Cup addresses this misreading directly. The genuine Epicurean position — that the goal is the fullest cup of genuine pleasures available to a person given his nature and circumstances — is the opposite of the last man’s philosophy. The last man is what Epicurean philosophy looks like through the distorting lens of its enemies.

Nietzsche’s contempt for the last man does not target pleasure as such. It targets the smallest, most timid, most unambitious version of pleasure — the version that has given up on everything that requires genuine engagement and genuine risk.

Noble (vornehm) and Base/Mean (gemein)

These constitute Nietzsche’s primary evaluative pair, introduced in Beyond Good and Evil and developed in On the Genealogy of Morals. These terms do not primarily describe social class. They describe a fundamental orientation toward valuation itself.

The noble person creates values by affirmation — beginning with the recognition of what is excellent, strong, admirable, life-enhancing, and declaring it good. The evaluation flows from fullness and strength. The noble person says “I am good” and defines the good by what he is and what he does. The mediocre, failing, or resentful version of things is what is “bad” by contrast — but “bad” here is merely a secondary, relatively unimportant category.

The base or mean person reacts. Such a person begins not with affirmation of himself but with rejection of what oppresses or threatens him. He first says “you are evil” and then defines himself as “good” by contrast with the evil enemy. This reactive, secondary, dependent mode of valuation is what Nietzsche calls ressentiment.

Epicurean ethics is structurally noble in Nietzsche’s sense: it begins with the affirmation of pleasure as the natural good, identified through the honest reading of what nature provides as its guides (sensation, feeling). It does not define the good by contrast with an enemy. It does not begin with a denunciation of vice from which virtue is defined by negation.

Master Morality and Slave Morality

These terms are the central distinction in On the Genealogy of Morals (First Essay). These are not descriptions of social groups but of two fundamentally different modes of valuation.

Master morality is the original, affirmative mode: the powerful, the excellent, the life-affirming define themselves as good and define the weak, the failing, the diminished as merely “bad” (not evil). The evaluation flows from strength and self-affirmation. Good and bad, in this framework, are not moral categories — they are comparative assessments of vitality and excellence.

Slave morality is the reactive, resentment-driven inversion: those without power to impose their values by strength develop a psychological reversal in which weakness, suffering, and renunciation become “good” and strength, pleasure, and worldly success become “evil.” The Beatitudes in the Sermon on the Mount are the clearest statement of slave morality in the canonical literature: the meek, the poor in spirit, those who mourn are declared blessed. The powerful, the successful, the happy in the ordinary sense are implicitly condemned.

The key inversion: in slave morality, the primary category is evil (the enemy, the oppressor, the strong), and “good” is defined reactively by contrast. In master morality, the primary category is good (what I am, what I affirm) and “bad” is a secondary, almost indifferent designation of what fails to meet that standard.

The philosophical consequence that Nietzsche draws is that the entire Christian-Kantian moral tradition operates in the mode of slave morality — even when, as in Kant, it presents itself as purely rational and universal. Its structure is reactive and resentment-driven at the root, whatever the formal apparatus built over it.

For the Epicurean reading: the ancient attack on Epicurean pleasure — that it is “merely bodily,” “selfish,” “brutish,” the pleasure of swine — is an exemplary piece of slave-morality rhetoric. It defines the opponent as evil (the sensualist) and the condemner as virtuous by contrast. The charge is not a philosophical argument. It is the characteristic move of a value system whose strength lies entirely in the denunciation of the alternative.

Ressentiment

Nietzsche uses the French word deliberately — it is not quite the same as the English “resentment.” Ressentiment is the specific psychological condition in which the inability to respond to a threat or oppression through direct action produces a creative inversion: the oppressed develop a value system that converts their weakness into virtue and their oppressors’ strength into evil.

Ressentiment has several distinctive features: it is reactive rather than creative; it is indirect rather than direct; it requires an enemy against whom the self is defined; it festers over time rather than discharging itself in action; and it disguises its origin in impotence by presenting itself as moral superiority.

Nietzsche’s most significant genealogical claim is that what presents itself as the highest moral achievement of Western civilization — the universal love, equal dignity, and compassion ethics of Christianity and its secular successors — is structurally rooted in ressentiment. What looks like the most elevated and spiritual orientation is, at its genetic root, a transformation of impotent rage at those who have what you lack.

The specifically anti-Epicurean function of ressentiment in intellectual history: the most effective ancient attacks on Epicurean philosophy — the charge that Epicurus was an atheist, that his followers were promiscuous, that his philosophy was merely an excuse for self-indulgence — were products of ressentiment rather than philosophical refutation. The Platonist and Stoic who could not answer Epicurus’s arguments nevertheless could, and did, construct a social image of “the Epicurean” that made the philosophy contemptible rather than engaging with it on its merits.

Transvaluation of All Values (Umwertung aller Werte)

Sounds like nihilism or the destruction of values. It is Nietzsche’s most ambitious positive project: the reversal of the slave-morality inversion that has dominated Western civilization for two thousand years. Transvaluation does not mean the abolition of values but the reorientation of the entire evaluative framework — from reactive, life-denying, Hinterwelt-oriented valuation back to affirmative, life-embracing, this-world-oriented valuation.

The transvaluation Nietzsche sought would not produce a world without values. It would produce a world in which strength, pleasure, honesty, life-engagement, and full creative expression of genuine capacity are recognized as good — not in defiance of anything, but as the direct affirmation of what life actually is.

Part Three: Terms About What Passes for Morality

”Morality” (Moralität) — Always Used with Suspicion

When Nietzsche writes “morality” without qualification, he almost invariably means it critically — referring to the slave-morality system of Christian-Kantian ethics that he is attacking. Genuine ethics, in Nietzsche’s framework, is not what “morality” has been. It is what a clear-eyed assessment of life and its genuine goods would produce.

This is a source of enormous confusion in Nietzsche commentary, because readers assume that Nietzsche’s attacks on morality are attacks on ethics as such. They are not. They are attacks on a specific historical form of ethics — the reactive, life-denying, Hinterwelt-dependent form — presented as if it were the only form ethics could take.

Virtue (Tugend) — Frequently Inverted

In the dominant Western tradition, “virtue” names the qualities produced by the subordination of natural desire to rational principle or divine command — qualities that are typically defined in opposition to pleasure, inclination, and self-interest. The “virtuous” person is the one who has most successfully suppressed what nature provides in favor of what reason or God requires.

Nietzsche’s attack on this concept of virtue is fundamental. “A virtue must be our invention; it must spring out of our personal need and defense. In every other case it is a source of danger.” (The Antichrist, §11) Virtue that is imposed from outside — that is adopted because it is universally required, because duty demands it, because God commands it — is not virtue. It is compliance. And compliance, regardless of its content, is the destruction of what Nietzsche values most: genuine self-creation from one’s actual nature.

The Epicurean parallel: Epicurus treats virtue as instrumental — a set of tools that the wise person uses to achieve genuine pleasure. Virtue is not the goal; it is the most reliable instrument for reaching the goal. This makes Epicurean virtue specifically “our invention” in Nietzsche’s sense — it emerges from the honest assessment of what actually works to produce a good life, not from an external command or universal rational principle.

Conscience and Bad Conscience (schlechtes Gewissen)

“Conscience” sounds like the faculty of moral self-awareness — the inner voice that directs us toward the good. For Nietzsche, in On the Genealogy of Morals (Second Essay), it is something far darker in its historical origin.

Bad conscience is the result of the internalization of instincts. When human beings were incorporated into stable social structures that forbade the direct discharge of aggressive, assertive, expansive instincts outward — when you could no longer simply act on your drives — those drives turned inward. The energy that could not be directed outward toward genuine objects became directed inward, toward the self. Bad conscience is self-directed cruelty — the self-torture of an organism whose drives have been blocked and must go somewhere.

What organized religion did, in Nietzsche’s genealogy, was harness this bad conscience to theological frameworks. Guilt — specifically the sense that one is inherently, cosmically indebted to God — became the vehicle by which bad conscience was institutionalized. The ascetic priest (see below) turned the self-torture of bad conscience into a manageable social technology: the suffering people feel can be given a cause (their own sinfulness), which simultaneously explains their pain and provides a direction for the self-directed cruelty (repentance, penance, self-mortification).

The Epicurean relevance: one of the central projects of Epicurean philosophy is precisely the dissolution of groundless guilt and fear. The fear of divine punishment, the sense of cosmic indebtedness to supernatural powers, the experience of one’s own pleasure as a source of moral danger — these are, from an Epicurean standpoint, false beliefs about the universe that generate unnecessary pain. What Nietzsche analyzes genealogically, Epicurus attacks philosophically: both arrive at the same target, though by different routes.

Pity (Mitleid) — “The Praxis of Nihilism”

Sounds like one of the highest moral qualities. In nearly all Western moral philosophy from Christianity through Schopenhauer, compassion or pity is treated as either the highest virtue or its foundation. For Nietzsche, it is the most philosophically dangerous of all the values that slave morality has elevated.

“Pity is the praxis of nihilism… By means of pity, the drain on strength which suffering itself already introduces into the world is multiplied a thousand-fold.” (The Antichrist, §7)

Nietzsche’s argument is specific. Pity does not reduce suffering. It extends and multiplies suffering by preserving what is ripe for dissolution — by intervening to sustain weakness, failure, and deterioration that would otherwise run their course. Moreover, pity makes suffering the central category of moral attention. An ethics built on pity places those who suffer at the center — which means that suffering itself, in a perverse feedback loop, becomes the primary claim to moral importance. The greatest sufferer has the greatest moral claim. This is the inversion that slave morality requires.

Nietzsche also attacks pity as psychologically self-indulgent: the person who pities expands his own suffering unnecessarily. Pity does not merely recognize the sufferer’s pain; it imports that pain into the pitier. If I am pained by every pain I witness or imagine, I have not helped the sufferer — I have merely made myself suffer too, and typically in a way that is more about my own emotional response than about any genuine help rendered.

The Epicurean position on compassion and friendship is carefully distinguished from pity of this kind. Epicurean friendship is built on shared pleasure — the genuine enjoyment of one another’s company, the mutual support that makes each person’s pleasures larger and pains smaller. This is quite different from an ethics of pity in which shared suffering is the foundation. Epicurean friends help each other not primarily by sharing each other’s pain but by contributing to each other’s flourishing.

The Ascetic Ideal (das asketische Ideal)

The subject of the Third Essay of On the Genealogy of Morals — the longest and most sustained analysis in Nietzsche’s work. The ascetic ideal is the orientation toward self-denial, self-mortification, the minimization of natural pleasure, and the elevation of suffering as spiritually valuable.

Sounds like a description of a particular religious practice. It is Nietzsche’s term for the deepest philosophical pathology he identifies in Western civilization — the will to nothingness dressed as the will to transcendence. The ascetic ideal says: the natural pleasures of the body and of worldly engagement are obstacles to the highest life; genuine worth is found in their suppression; the person who denies himself most completely is the most admirable.

Nietzsche’s most unexpected argument is that the ascetic ideal is not simply the enemy of meaning but actually the last available source of meaning in a civilization that has lost any other ground. When the question becomes “what is the point of suffering?” — a question that demands an answer because suffering without meaning is unbearable — the ascetic ideal provides one: suffering is the path to transcendence, the proof of spiritual worth, the cost of salvation. The ascetic ideal gives suffering a meaning, even if that meaning is life-denying. That is why it has been so culturally powerful and so long-lasting.

The Epicurean philosopher and the Nietzschean both refuse the ascetic ideal, but from different directions. Epicurus refuses it because the premise is wrong: there is no transcendence, no divine reward for suffering, no supernatural reason to deny natural pleasure. Nietzsche refuses it because even setting aside the metaphysical premise, the cultivation of suffering as spiritually valuable is the deepest available form of life-denial — it takes the thing most opposed to flourishing and makes it the path to the highest life.

The Ascetic Priest

The social agent of the ascetic ideal. The ascetic priest is not primarily a figure of genuine spiritual authority but a manager of suffering — specifically, the suffering of the herd of people who are sick, weak, and in pain and need some account of why they hurt. The ascetic priest provides that account: you are suffering because you are sinful, because you have failed to deny yourself adequately, because God is testing you. This simultaneously explains the pain and provides a direction for the self-directed cruelty of bad conscience — repentance, penance, renewed self-mortification.

Nietzsche’s disturbing conclusion is that the ascetic priest is actually the agent of health for the herd, in the only way the herd can receive help: not by removing the suffering (which is beyond the priest’s power) but by giving it a meaning that makes it bearable. The religion that tells the suffering that their suffering is sacred is, in the short term, more effective at managing mass suffering than any philosophy that simply points out that the suffering is unnecessary.

The anti-Epicurean implication is significant: Epicurean philosophy offers a cure — the dissolution of groundless fears, the recognition that the universe does not punish, that death is not a passage to judgment — but requires genuine philosophical engagement that most people, especially people already suffering, cannot easily undertake. The ascetic priest offers immediate comfort at the cost of long-term philosophical enslavement. This is, Nietzsche implies, why Epicurus lost.

Part Four: Terms About Knowledge and Philosophy

Consensus Sapiensium — “Agreement of the Wise”

One of Nietzsche’s most cutting phrases, used in Twilight of the Idols (“The Problem of Socrates,” §1). The phrase sounds like the accumulated wisdom of the greatest philosophical minds — the settled verdict of those who know best. Nietzsche uses it to mean exactly the opposite: the more confidently something is translated as “the agreement of the wise,” the more carefully you must read, because what Nietzsche means is an agreement he is about to expose as a shared mistake.

It is Nietzsche’s term for something entirely opposite: the almost universal agreement among the great philosophers of Western history that life in this material world is not worth much. From Socrates (life is a disease, death the cure) through Plato (this world is shadow) through Schopenhauer (this world is built on suffering) through the Kantian ethical framework (happiness is irrelevant to moral worth), the “agreement of the wise” converges on the devaluation of life as actually lived.

Nietzsche’s diagnosis: this convergence is not wisdom. It is shared pathology. The same decadent orientation toward life — the same inability to face the harsh reality of material existence without retreating into the fiction of a better world — manifests as the consensus sapiensium when multiplied across centuries of philosophical tradition. The fact that so many great minds arrived at the same life-denying conclusion is not evidence of its truth. It is evidence that they were all suffering from the same intellectual disease.

The Epicurean position is the exception — the counter-consensus that says life in this world, properly understood and properly approached, is genuinely worth living, and that genuine happiness is available to those who pursue it with wisdom. Nietzsche recognized this, and it is why he consistently presents Epicurus as the outsider who refused to join the consensus sapiensium.

Decadence (Dekadenz)

Sounds like moral depravity or excessive indulgence in pleasure. This is exactly backwards. In Nietzsche’s vocabulary, decadence is life-denial, not excess of life. It is not the person who pursues pleasure too ardently who is decadent. It is the person who retreats from life into a Hinterwelt, who denies that the natural world and natural feelings can be the standard for genuine living, who mistakes withdrawal and self-mortification for elevation.

Decadence, for Nietzsche, is a philosophical symptom — a sign of weakness in confronting material existence that manifests as the construction of a “truer” world elsewhere. Plato was decadent. Paul was decadent. Kant was decadent. Schopenhauer was decadent in the most extreme degree — he said openly what the others only implied: this world is built on suffering and the best response is progressive mortification of the will-to-live.

The specific application to philosophy: when a philosopher diagnoses the world as fundamentally bad, this is, for Nietzsche, a symptom of the philosopher’s own condition. Philosophy cannot be neutral on the question of the value of life, because to be alive is to be a party in the dispute. The philosopher who declares life bad is revealing that his own life is bad for him — not discovering a metaphysical truth about reality.

The Free Spirit (Freigeist)

Sounds like a person who is merely unconventional, liberal, or free-thinking in a casual sense. For Nietzsche, the free spirit is a specific philosophical achievement — the person who has genuinely freed himself from the inherited value system of the consensus sapiensium and is capable of genuine philosophical investigation without predetermined destinations.

The free spirit is distinguished from the merely skeptical by the fact that liberation from inherited values is a beginning, not an end. The mere skeptic dissolves values and stops. The free spirit uses the liberation to look at the world freshly, to allow genuine experience to replace inherited framework, to follow philosophy wherever it actually leads.

”The Philosophers” Used Ironically

When Nietzsche refers to “the philosophers” as a group, he almost invariably means the Western philosophical tradition from Socrates through Kant — and he almost invariably means it critically. “The philosophers” are the practitioners of the Hinterwelt, the architects of the consensus sapiensium, the people who used the prestige of systematic thought to dress up life-denial as wisdom.

The irony is that Nietzsche — the philosopher — uses this as a term of contempt for philosophy. He is contemptuous precisely of what philosophy has been, and he is attempting to show what philosophy should be: the honest investigation of what is actually the case, without the predetermined destination of affirming whatever makes life-denial philosophically respectable.

Instinct (Instinkt) Over Reason

In the dominant Western philosophical tradition, particularly Kantian ethics, instinct and natural inclination are what reason and duty must overcome. Moral worth requires suppressing what comes naturally in favor of what abstract rational principle demands. The “merely animal” in human beings — the natural feelings — must be transcended by the rational will.

Nietzsche reverses this entirely. Instinct — the deep, felt orientation of a living creature toward what serves its genuine life — is more reliable than abstract reason divorced from life. Reason that overrides instinct is not elevated but distorted: it has severed itself from its only genuine source of feedback — the feelings of life itself — and operates in a vacuum that it fills with inherited prejudices, social pressures, and theological residues dressed as rational necessities.

“The most subtle instincts and the greatest experience conspire together in what we call ‘good taste’… Good taste resists both too much and too little; in every case it insists on the appropriate.” (Twilight of the Idols, “Expeditions of an Untimely Man,” §7)

The Epicurean parallel is the Canon: sensation, anticipations built from accumulated experience, and the feelings of pleasure and pain are the three natural criteria of truth. None of them is purely “rational” in the Kantian sense — none operates independently of lived experience. All three are, in Nietzsche’s vocabulary, forms of instinct: natural orientations toward genuine goods, refined through experience. What both Epicurus and Nietzsche refuse is the claim that a faculty of pure reason, operating above and against these natural instruments, has access to truths they cannot reach.

Part Five: Terms About Life-Affirmation

Will to Power (Wille zur Macht)

Almost universally misread as desire for political domination, military conquest, or the subordination of other persons. This misreading has been used to associate Nietzsche with authoritarianism and even with Nazism, despite Nietzsche’s explicit contempt for nationalism and anti-Semitism, which he attacked repeatedly and specifically.

What Nietzsche actually meant by the will to power is the fundamental drive of every living thing toward growth, expression, self-overcoming, and full engagement with life. It is not primarily about power over others. It is about the organism’s characteristic orientation toward the full development and expression of what it is — toward overcoming the resistances that life presents, not in order to dominate but in order to grow.

Nietzsche’s definition of happiness in The Antichrist (§2) is the most direct statement: “What is happiness? The feeling that power is growing — that a resistance is overcome.” This is not contentment. Not the satisfaction of having achieved minimum comfort. Not the equanimity of having reduced desire to what is easily satisfied. It is the felt engagement with genuine challenge — the sense of growth against resistance.

The comparison with Epicurean pleasure requires nuance. Nietzsche was not an Epicurean on this point — he explicitly noted that Epicurus focused more on pleasure and community while he himself focused more on struggle and self-overcoming. But the structural parallel is real: both are pointing to something that genuine life feels like, as opposed to the absence of feeling that the consensus sapiensium had elevated into a philosophical goal. Nietzsche’s will to power and Epicurus’s pleasure (in its full sense, including the active pleasures of intellectual engagement, genuine friendship, and the full cup of human capacity) are both affirmations of this-world engagement against the life-denial of the tradition both attack.

Amor Fati — Love of Fate

Sounds like fatalism: passive acceptance of whatever happens, resignation to destiny. It is the opposite. Amor fati is Nietzsche’s term for the active, joyful affirmation of everything that is and has been — not despite its difficulty and pain, but including it. The person who practices amor fati does not merely tolerate what he cannot change. He wills it — he affirms it as part of the only world there is and the only life available.

“My formula for greatness in a human being is amor fati: that one wants nothing to be different, not forward, not backward, not in all eternity. Not merely bear what is necessary, still less conceal it — all idealism is mendaciousness in the face of what is necessary — but love it.” (Ecce Homo, “Why I Am So Clever,” §10)

The contrast with Stoic amor fati is important and often missed. The Stoic who accepts fate does so because fate is the expression of the divine rational order — the logos — and alignment with that order is the Stoic’s goal. The Stoic’s acceptance has a metaphysical backstory: things are as they are because reason governs the cosmos, and the wise person accepts this because wisdom means alignment with cosmic reason.

Nietzsche’s amor fati has no such backstory. There is no cosmic rational order, no divine governance, no logos. The universe is not arranged for human benefit. Things are as they are because that is how they are — and the challenge is to affirm that without consolation, without fiction, without the backstory that makes acceptance psychologically easier.

The Epicurean parallel is imperfect but real. Epicurean philosophy does not promise that the universe is arranged for human benefit — the universe operates by atomic physics without reference to human welfare. What Epicurean philosophy offers is a framework for living well within that universe as it actually is, without the groundless fears that a false picture of it generates. This is not amor fati in Nietzsche’s precise sense, but it shares the fundamental insistence on accepting the actual universe rather than consoling oneself with a fiction of it.

Eternal Recurrence (ewige Wiederkehr)

The most discussed and most misunderstood concept in all of Nietzsche — and the one most likely to be taken as a cosmological claim when it is actually a psychological and philosophical test.

The thought experiment: suppose everything that has ever happened — every moment of your life, every pleasure and every pain, every success and every failure — will recur, in exactly the same sequence, an infinite number of times. How do you respond to that thought?

Nietzsche does not assert eternal recurrence as a physical truth about the universe (though some of his notes suggest he thought it might be physically defensible). He uses it as a hammer test: would you say yes to your life if you knew you had to live it again, infinitely? The person who genuinely affirms life — who lives in a way consistent with amor fati, who wills the full engagement with genuine existence — can say yes. The person who is living in a way he would not choose to repeat is revealed, by the test, to be living in bad faith.

The connection to Epicurean philosophy: Epicurus’s own test of the good life is in some ways parallel. The Epicurean question is whether, when pleasure and pain are honestly reckoned across the full span of life, pleasure predominates. This requires the same kind of unflinching honest assessment that the eternal recurrence demands — the willingness to evaluate life without consoling fictions, against the actual standard of what you genuinely feel rather than what you have been told you should feel.

Health (Gesundheit) and Sickness (Krankheit)

Used throughout Nietzsche as philosophical rather than medical terms. Health is not the absence of physical illness but the philosophical condition of genuine life-engagement — the orientation toward this world and its genuine goods, the capacity to evaluate without the distortions of bad conscience, ressentiment, or the ascetic ideal.

Sickness is the philosophical condition of life-denial — the retreat into the Hinterwelt, the construction of compensatory fictions to make material existence bearable, the inversion of values by which weakness becomes virtue. Sickness in this sense produces the consensus sapiensium: the agreement that life is not worth much is the symptom of people for whom life, as actually experienced, is genuinely bad.

Nietzsche’s controversial move is to suggest that the great philosophers of the Western tradition were, in this philosophical sense, sick — and that their philosophical systems are diagnoses of their conditions rather than discoveries about the nature of reality. Socrates was sick; his philosophy of transcending the body through reason reflects it. Paul was sick; his theology of sin, guilt, and grace reflects it. Schopenhauer was sick; his metaphysics of universal suffering reflects it.

This is not primarily an ad hominem attack. It is a methodological claim: when evaluating a philosophical position, the question of where it comes from — whether it emerges from genuine honest investigation or from the attempt to make one’s own particular suffering cosmically significant — is philosophically relevant.

Self-Overcoming (Selbstüberwindung)

Easily confused with the Christian and Kantian project of mastering one’s lower impulses — suppressing desire, overcoming the merely animal in human nature, subordinating feeling to rational principle.

For Nietzsche, self-overcoming means something entirely different: the creation of new values from one’s own genuine depth, the genuine philosophical and personal development that transforms what one is and what one can do. Self-overcoming is not the suppression of instinct but the refinement and re-creation of it — the person who genuinely overcomes himself does not become more compliant with external standards but becomes more genuinely what he is at his best.

The passage from Thus Spoke Zarathustra that most clearly states this: “And life itself told me this secret: ‘Behold,’ it said, ‘I am that which must always overcome itself.’” Life is not static. Living things grow or they die. The person who is not genuinely developing — who has settled into a comfortable position and defended it against all challenge — is not living at full capacity, whatever his formal moral compliance.

Part Six: Terms About the Cultural Moment

The Death of God

Perhaps the most misunderstood Nietzschean concept in popular culture. “God is dead” is taken as a cheerful announcement of atheism, a celebration of having escaped religious superstition.

Nietzsche’s intent was the opposite of cheerful. The death of God — more precisely, the loss of credibility of the entire supernatural-moral framework on which Western civilization had built its values — is for Nietzsche a cultural catastrophe whose full implications most people had not yet grasped. The madman who announces God’s death in The Gay Science (§125) does not celebrate; he mourns. “What have we done when we unchained this earth from its sun?… Do we not ourselves have to become gods simply to appear worthy of it?”

The problem is not the loss of God as such. It is that Western civilization had built its entire moral framework on the assumption of a supernatural authority — and that framework, even when people stopped believing in God, did not disappear. The morality remained without its foundation. The guilt, the universal obligations, the devaluation of natural pleasure, the elevation of suffering — all remained in place, maintained now by social habit and the prestige of the Kantian-Humanist tradition, but without the supernatural backstory that had originally given them their authority.

The result is nihilism: not the dramatic proclamation that nothing matters, but the slow collapse of a value system whose supports have rotted away, leaving a civilization that cannot say convincingly why anything matters, and which either despairs or reaches for one substitute after another.

“God is dead; but given the way of men, there may still be caves for thousands of years in which his shadow will be shown. — And we — we still have to vanquish his shadow, too.” (The Gay Science, §108)

The connection to the Epicurean project: Epicurus abolished the supernatural foundation of moral and existential anxiety not by announcing that “God is dead” but by demonstrating that the gods, whatever they are, do not intervene in human affairs — and that the entire architecture of divine reward, punishment, and cosmic supervision is therefore a fiction that generates nothing but unnecessary fear. The Epicurean dissolution is not primarily the loss of something — it is the liberation from a burden that should never have been imposed.

Nihilism

Not primarily a philosophical position meaning “nothing has value” but a cultural condition — the emptiness that results when the supernatural-moral framework loses its credibility but is not replaced by any genuine alternative. Nihilism is the aftermath of the death of God in a civilization that cannot generate new values to replace the ones that depended on supernatural authority.

Nietzsche distinguished between passive nihilism (despair, resignation, the recognition that nothing matters accompanied by the inability to do anything about it) and active nihilism (the deliberate destruction of inherited values as a precondition for genuine creation). Passive nihilism is the disease. Active nihilism is a stage through which one must pass on the way to genuine transvaluation.

The most dangerous form of nihilism, for Nietzsche, is not the dramatic kind that announces its own meaninglessness. It is the quiet kind that maintains the inherited morality — guilt, universal obligations, the devaluation of natural pleasure, the subordination of feeling to duty — while losing the conviction that any of it actually matters. This produces a civilization of people who go through the motions of inherited moral frameworks without genuine engagement, covering the emptiness with the pursuit of the last man’s minimal comforts.

Part Seven: Terms Directly Relevant to Epicurean Physics

”Becoming” (Werden)

As above — but it is worth stating specifically the physical implication. Nietzsche’s celebration of Werden over Sein — of the flowing, changing, dynamic world over the Platonic world of eternal static being — directly parallels Epicurean physics. The universe of atoms and void in constant motion is a universe of becoming, not being. Epicurean physical theory provides no stable, eternal entities at the level of the observable world — only atoms and their temporary combinations. The compounds that constitute everything we experience are in constant flux. This is not a deficiency. It is what reality is.

Nietzsche makes the further point (in Twilight of the Idols, “Reason in Philosophy,” §5) that the concept of “being” as the highest reality is an artifact of grammar — of the subject-predicate structure of language that projects agents behind actions and substances behind processes. Epicurus does not state the argument in these terms, but the implication of his physics is the same: there are no eternal substances, only patterns of motion.

”Things-in-Themselves” (Ding-an-sich)

Kant’s term for reality as it is independently of any cognitive framework — the world as it is “in itself,” behind or beneath the appearances our perceptual and conceptual apparatus delivers. For Nietzsche, this is not a philosophical insight but a philosophical mistake — the reinvention of the Hinterwelt in epistemological vocabulary.

The Epicurean relevance: Epicurean canonics (the theory of knowledge) has no place for things-in-themselves that are systematically inaccessible to sensation. What sensation reports is real — not because sensation is infallible about everything, but because there is no “behind” the sensory world to which sensation fails to give access. The atoms are not things-in-themselves in the Kantian sense; they are inferred from what we observe through the same process of extrapolation from sensation that all genuine knowledge employs.

Part Eight: Terms Directly Relevant to Epicurean Canonics

”The Senses Do Not Lie” (Die Sinne lügen nicht)

Stated directly in Twilight of the Idols (“Reason in Philosophy,” §2). This sounds like naive empiricism. It is the Nietzschean equivalent of the Epicurean Canon’s most foundational claim: that sensation, as such, is not the source of error. Error enters in what reason adds to sensory reports.

Nietzsche: “What we make of their testimony, that alone introduces lies — for example, the lie of unity, the lie of thingness, of substance, of permanence… ‘Reason’ is the cause of our falsification of the testimony of the senses.”

Compare Epicurus’s Canon: all sensations are true; false judgments arise when we add more to sensory reports than the reports themselves warrant. The classic example is the oar that appears bent in water. The sensation is accurate — this is what an oar in water looks like from this angle. The error is the judgment that the oar is actually bent. Remove the judgment and the sensation is blameless.

Both Nietzsche and Epicurus are attacking the same position: the Platonic-rationalist claim that the senses are inherently deceptive, that genuine reality is inaccessible to them, and that reason — freed from sensory distortion — has access to a truer picture. Both deny this. The senses report accurately. What produces falsehood is the mind’s interpretive additions.

”Honesty” (Redlichkeit) as Philosophical Courage

In Nietzsche’s vocabulary, intellectual honesty (Redlichkeit) is the specific virtue of following philosophical investigation wherever it actually leads — even when it undermines comfortable beliefs, prestigious traditions, or deeply held personal convictions.

The consensus sapiensium is, among other things, a failure of intellectual honesty: the great philosophers arrived at life-denying conclusions not by following the evidence honestly but by starting with the conclusion (this world is insufficient; a truer world must exist) and working backward to arguments that support it. Kant’s admission that he was preparing “a firm foundation for those majestic moral edifices” — the structures already built — is for Nietzsche the confession of intellectual dishonesty at the root of the entire Kantian enterprise.

The Epicurean parallel: Epicurus began with the question of what the universe actually is and followed the investigation honestly through to its conclusions — even the uncomfortable ones (the gods do not intervene; death is the end of sensation; there is no cosmic moral order). The Epicurean commitment to following the Canon wherever it leads is the ancient counterpart to what Nietzsche calls Redlichkeit.

Part Nine: Terms Directly Relevant to Epicurean Ethics

Happiness (Glück) — Redefined

In Nietzsche’s famous formulation from The Antichrist (§2): “What is happiness? The feeling that power is growing — that a resistance is overcome.”

This sounds nothing like the conventional meaning of happiness as contentment, well-being, or the satisfaction of desires. Nietzsche specifically contrasts this definition with what he calls “English happiness” — the utilitarian calculus of pleasure and pain that he considered flat and reductive (specifically targeting Bentham and Mill). For Nietzsche, happiness is not a state of comfortable equilibrium but a felt sense of genuine engagement and growth.

The distinction from Epicurean pleasure is real but should not be overstated. Nietzsche was not an Epicurean and said so explicitly — he found Epicurus too focused on tranquility, too willing to retreat from conflict, too much a philosopher of reduction rather than of growth. But in the specific context of the anti-consensus-sapiensium argument, both are pointing at the same basic target: the life-denying tradition that declared the feelings irrelevant to genuine value and that elevated suffering, duty, and transcendence over genuine engagement with this world.

”English Happiness” — Nietzsche’s Contemptuous Phrase for Utilitarian Calculus

Nietzsche’s contemptuous phrase for the utilitarian tradition of Bentham and Mill — the measurement of pleasure and pain in quantitative units, the calculation of aggregate welfare. He used this specifically to distinguish his own account of what matters in life from what he saw as a reductive and shallow account of pleasure.

It is important for Epicureans to note that Nietzsche’s attack on “English happiness” is not an attack on Epicurean pleasure. Nietzsche admired Epicurus and specifically praised him as a philosopher who escaped the consensus sapiensium. His complaint with utilitarian “happiness” is that it reduces the evaluation of life to a quantitative calculation — something quite different from the Epicurean account, which is deeply personal, qualitative, and tied to the specific nature and circumstances of the individual living it.

”Egoism” (Egoismus) — Reclaimed

In the dominant moral tradition, “egoism” or self-interest is the primary vice — the thing that genuine virtue must overcome. Morality, on this account, is precisely the subordination of self-interest to duty, universal obligation, or compassion for others.

Nietzsche reclaims the term. What the slave-morality tradition condemns as egoism is simply the natural orientation of a living creature toward its own flourishing — which is, as Epicurus would recognize, what nature has equipped every living thing to do. The condemnation of self-interest as such is the slave-morality move that declares the powerful’s strength “evil” and the weak’s weakness “good.”

This does not mean Nietzsche endorsed crude selfishness or indifference to others. His account of noble, health-oriented valuation includes genuine care for those one genuinely loves. What he rejected is the moral tradition that makes the subordination of self to abstract universal obligation the definition of virtue — which he saw as both psychologically dishonest (most people who claim to act from pure duty are rationalizing ressentiment) and philosophically confused (there is no “universal” standpoint from which genuine goods can be evaluated independently of the particular lives in which they are experienced).

The “Chandala Values” (Tschandala-Werte)

A term from The Antichrist (§56–57). “Chandala” is a Sanskrit term for the lowest caste in the Hindu social hierarchy. Nietzsche uses it to describe the values of Platonism and Christianity — the “values of the chandala”: the demotion of the body, the denigration of pleasure, the elevation of suffering, the promise that what is lowest here will be highest there.

The point Nietzsche is making is a reversal of the tradition’s own self-presentation: what presents itself as the highest (the spirit over the body, duty over pleasure, the transcendent over the material, the suffering meek over the flourishing strong) is, in Nietzsche’s analysis, the lowest — the product of weakness, ressentiment, and the inability to face material existence honestly. The chandala values are the values of the lowest point dressed in the clothing of the highest aspiration.

For Epicurean philosophy, this is relevant: the long tradition that presented Epicurean pleasure as “low” and the Platonic or Stoic transcendence of pleasure as “high” is, on Nietzsche’s analysis, the chandala tradition projecting its own inversion onto the one philosophy that refused it.

Part Ten: Nietzsche on Epicurus Directly

Having established the vocabulary, it is worth collecting what Nietzsche actually said about Epicurus, since this is sometimes lost amid the larger argument.

From The Antichrist (§58): “One has but to read Lucretius to know what Epicurus made war upon — not paganism, but ‘Christianity’, which is to say, the corruption of souls by means of the concepts of guilt, punishment, and immortality… Epicurus would have won; each respectable mind was Epicurean in the Roman Empire: and then Paul arrived.”

From Human, All Too Human (§68, and related passages): “The awakening sciences have allied themselves point by point with the philosophy of Epicurus, but point by point rejected Christianity.”

From Twilight of the Idols (“What I Owe the Ancients”): Nietzsche named Epicurus as one of the thinkers he most admired — specifically for his insistence that this world is sufficient, that natural feeling is the guide to genuine goods, and that the project of philosophy is to enable a good life in the actual world rather than to prepare for a better world elsewhere.

From The Gay Science (§45): “Epicurus — yes, I am proud that I perceive the character of Epicurus differently from perhaps everyone else.” He goes on to describe Epicurus as the man who had “the happiness of the afternoon of antiquity” — who had found, in the natural world and natural friendship, sufficient ground for genuine contentment without any recourse to transcendence.

From Beyond Good and Evil (§270): Nietzsche describes Epicurus as achieving something rare: genuine philosophical health. Against the parade of decadent philosophers whose systems are symptoms of their sicknesses, Epicurus stands as an example of philosophical health — not perfect, not identical with what Nietzsche himself sought, but genuinely located in this world and genuinely capable of genuine happiness within it.

Part Eleven: What Nietzsche Does Not Say That Is Often Attributed to Him

Before concluding, it is worth specifying several things Nietzsche did not mean by his most-misused terms.

“Will to power” does not mean: wanting to rule others, national conquest, political domination, the strong exploiting the weak, or anything the Nazis subsequently attributed to it. Nietzsche was explicit in his contempt for German nationalism, anti-Semitism, and the political ambitions of his contemporaries. Will to power is about the individual organism’s orientation toward its own fullest expression, not about imposing that expression on others.

“The death of God” does not mean: atheism as a cheerful philosophical position, the liberation of humanity from all constraint, or an invitation to do whatever one pleases. It is a diagnosis of cultural crisis, not a celebration.

“Eternal recurrence” does not mean: a scientific claim that history literally repeats, a consoling doctrine that everything comes around again, or an excuse for fatalism. It is a thought experiment designed to test the quality of one’s engagement with life.

“The Übermensch” does not mean: a racially superior human type, a physical or military conqueror, or any political figure whatever. It is Nietzsche’s aspirational figure for a human being who has genuinely created values from the depth of his own genuine nature rather than inheriting and complying with the slave-morality framework.

“Amor fati” does not mean: passive resignation, accepting whatever happens because one cannot change it, or fatalistic indifference to the difference between good and bad outcomes. It is the active, creative affirmation of everything that is, including what is hard and painful, as the condition of the only world there is.

Conclusion: Why This Matters for Epicurean Philosophy

The pattern running through all of Nietzsche’s most cutting terms is not a stylistic quirk. It is the intellectual form taken by the same project Epicurus conducted in different circumstances and different vocabulary two millennia earlier: the refusal of the Hinterwelt, the affirmation of this world as the real world, the insistence that the feelings nature provides are the standard by which genuine goods are recognized, and the demolition of the philosophical apparatus that had been constructed to make life-denial look like wisdom.

Understanding Nietzsche’s terms correctly means recognizing:

That the consensus sapiensium is not wisdom but the shared pathology of philosophers unwilling to face material existence honestly
That “true world” is Nietzsche’s label for a fiction — he puts it in quotes to signal he is naming something to be exposed, not a genuine reality
That “decadence” means life-denial, not pleasure
That “last man” is the worst insult, not a neutral description
That “will to power” names the full engagement with genuine life, not the domination of others
That “pity” names nihilism’s praxis, not virtue
That “the ascetic ideal” names the will to nothingness dressed as transcendence
That “morality” in Nietzsche almost always means the specific slave-morality tradition he attacks
That “conscience” in its historical development is not the voice of reason but the internalization of blocked drives
That “the senses do not lie” is not naive empiricism but the philosophical affirmation of nature’s instruments against the Platonic claim that reason transcends them

All of these inversions point in the same direction that Epicurean philosophy points. The genuine goods are here. The standard for recognizing them is natural feeling, honestly consulted. The tradition that declared this world insufficient, that placed the genuine goods elsewhere and demanded the sacrifice of natural pleasure as the price of admission to them, was wrong — whether in Plato’s vocabulary, Paul’s, Kant’s, or Schopenhauer’s. And the intellectual courage required to say so plainly, against the full weight of two thousand years of the opposing tradition, is what both Epicurus and Nietzsche share — more than any specific doctrine.
