The primacy of truth

The movement defines itself by a wager: the spread of light emancipates, darkness enslaves. To dare to know, uproot prejudice, publish the Encyclopédie, is to hold that no moral or political progress can be bought at the price of maintained ignorance, and that tutelages live off the darkness they cultivate.

Kant, What Is Enlightenment? (1784) · The Encyclopédie (1751-1772)

Disturbance comes not from things but from judgments: the discipline of assent requires adding nothing to impressions, saying of what happens exactly what it is. Stoic serenity is not a consolation but an exactness: to see the real as it is, is already to cease suffering from it unduly.

Epictetus, Handbook · Marcus Aurelius, Meditations

Facing his judges, Socrates prefers death to giving up examination: philosophizing is for him an assigned post one does not desert, and the worst misery is not to suffer but to live in the self-satisfied ignorance of what one thinks one knows. Care of the soul requires putting every opinion to the test, beginning with one's own.

Plato's Apology

Understanding is the sole salvation: each adequate idea increases our power of acting, and beatitude is nothing but the intellectual love born of knowledge of the third kind. Illusion is not first a fault but an impotence, a mutilated idea that makes us passive; the task is neither to mock nor to curse, but to understand, because understanding is already being free.

Ethics, IV-V · Political Treatise, I

Keeping the absurd alive requires rigging neither of its two terms: any consolation that lends the world a hidden meaning is an evasion, a philosophical suicide. Lucidity is not sadness but the honour of living: to see clearly and live all the same, without appeal, is the only greatness within reach.

The Myth of Sisyphus (1942)

Leaving the cave is painful, blinding, and yet the only liberation: to stay among the shadows is to take reflections for reality and live in chains without knowing it; knowing is not an ornament of happiness but the conversion of the whole soul toward what is. Yet the philosopher-king administers a noble lie to the city: the primacy of truth holds first for the soul being educated, and Plato accepts that the common order may itself rest on a myth.

Republic, VII · Republic, III

If bondage is only an illusory superimposition (māyā), no act or rite can undo it: only the knowledge that discriminates the real from the apparent dissolves illusion, as light dispels the snake one thought one saw in the rope. Liberation is not produced by knowledge: it is that very knowledge, recognizing that the self was never bound.

Upadeśasāhasrī · Commentaries on the Upaniṣads

The desire to know is not an instrument of happiness: it is constitutive of our nature, and contemplation (theōria), the most self-sufficient and continuous of activities, realizes what is highest in the human being; an accomplished life culminates in knowing, not in usefulness.

Metaphysics, I, 1 · Nicomachean Ethics, X

Since consciousness is what it is not and is not what it is, the standing temptation is bad faith: telling oneself one is a nature, a role, a thing, so as to flee the anguish of one's freedom. The minimal demand is not to conceal one's freedom from oneself: illusion about oneself turns freedom into fate.

Being and Nothingness, I (1943)

At the root of suffering lies not a fault but a mistake: ignorance (avidyā), which takes the impermanent for lasting and the selfless for a self. The path is a therapeutics of seeing, beholding things as they are; the teaching itself is only a raft, a means to be left behind once the far shore is reached.

Majjhima Nikāya (the raft parable)

Dare to know: leaving the minority for which one is oneself responsible requires relying on one's own understanding alone, and wherever a truth can be established, within the field of possible experience, it prevails without rival. But critique bounds that field: beyond it reason no longer knows, and claiming knowledge there would be dogmatism; rational faith does not replace an available truth there, it occupies a place that knowledge structurally cannot fill.

What Is Enlightenment? (1784) · Critique of Pure Reason, B preface (1787)

Knowledge begins with a purge: the idols, of the tribe, the cave, the marketplace, the theatre, are the natural and acquired illusions that distort the understanding, and the method's first task is to dispel them. The truth so won is not prized for itself alone: it proves itself by its works, in the service of the human condition.

Novum Organum, I (1620)

Knowledge is for him no speculative luxury: he wants to distinguish the true from the false in order to see clearly into his own actions and conduct his life with confidence. The method aims at shedding prejudice and hasty judgment, because a well-conducted life is regulated by established truths rather than received opinions.

Discourse on the Method, I (1637)

Religion is in his eyes an illusory happiness that consoles for a real misery: criticism does not target the belief for its own sake, but the social situation that makes such consolation necessary. Renouncing illusions only makes sense in order to transform the conditions that produce them; lucidity is not valued as a contemplative good, it is a condition of emancipation.

Critique of Hegel's Philosophy of Right, Introduction (1844)

His first rule of reason: do not block the way of inquiry. The methods that fix belief by tenacity or authority procure a real but fragile quiet; only inquiry, which accepts being disappointed by the real, durably stabilizes belief, by settling it on what does not depend on us.

The Fixation of Belief (1877)

Knowing the causes frees us from religio and from the fear of death: that is the Epicurean core. But Lucretius adds an avowal about manner: as the physician rims the cup of wormwood with honey, he coats an austere doctrine with poetry, sweetness in the service of truth, never in its place.

On the Nature of Things, I and IV

The knowledge of nature has a therapeutic office: to dissolve the terrors of the gods, of death and of the heavens; without these fears, he says, we would have no need of natural science. Truth is worth what it cures, neither a cult of knowledge nor a consoling illusion: the gods exist but do not concern themselves with us, and it is that very truth which brings peace.
