Before you read

Suppose someone discovers that a belief you cherish is mistaken. You might welcome the correction, resent it, or wonder whether knowing the truth will improve anything. Those reactions reveal different questions: is the belief true, why do you want to keep it, and what makes truth worth pursuing?

Nietzsche begins with the third question. The person who challenges everyone else's beliefs may still treat the value of truth as unquestionable. This book asks what happens when inquiry reaches the commitments that make inquiry matter.

You can begin here without having completed the earlier books. If you have read Thus Spoke Zarathustra, carry forward its question about creating values. Here Nietzsche examines the philosophers, habits of thought, and institutions through which valuations acquire authority.

Before reading, write two sentences explaining why you value honesty. Keep them throughout the course. We will distinguish telling the truth, seeking knowledge, and acknowledging one's motives; these activities need not have identical reasons or costs.

The main question: Can we investigate the value of truth without giving up the standards that make an investigation trustworthy?

Three things to notice

1. A question behind a question. In §1, how does asking where the will to truth comes from differ from asking what it is worth?
2. Values inside an argument. In §§2–6, look for a preference that presents itself as a discovery. Distinguish Nietzsche's proposal about motives from evidence that a particular argument fails.
3. The critic's inheritance. The Preface credits the struggle against dogmatism with producing intellectual strength. In §9, ask whether Nietzsche's picture of nature could itself express a valuation.

A way to read the passages

A preface about how philosophers approach their object

The Preface compares dogmatic philosophy with a clumsy suitor. The comparison attacks a way of approaching truth: solemnity, persistence, and the desire to possess an answer have been mistaken for adequate understanding. The opening is provocative before it becomes an argument.

Its image also treats women as objects of pursuit. Keep that feature visible. The book will later make explicit claims about women, and Reading 8 will ask whether its criticism of prejudice reaches those claims. An effective attack on dogmatism can still rely on assumptions that deserve criticism.

Nietzsche targets the separation of pure spirit and a good existing independently of particular lives and perspectives. Yet he credits the long struggle against this inheritance with developing a formidable tension of thought. The bow at the end of the Preface suggests an acquired capacity whose destination remains open. His free spirits inherit the strength of a struggle they have not simply left behind.

The stated date of the Preface is June 1885; the book was published in 1886. Its anticipation of a goal belongs to the writing's presentation of itself. It does not establish that Nietzsche has already supplied a complete replacement philosophy.

Asking what truth is worth changes the inquiry

§1 stages an encounter between the questioner and the force that makes questioning urgent. At first we might investigate the origin of a desire for truth: curiosity, fear of error, intellectual pride, or the demands of a practice. Nietzsche then asks about its value. Why prefer truth to uncertainty, ignorance, or deception?

An explanation of the desire does not yet justify or refute it. Someone may have learned honesty through fear of punishment and later defend it because trust makes cooperation possible. Conversely, an admirable wish to understand need not make every possible disclosure beneficial. These are our examples of the distinction, not histories established by Nietzsche.

Notice that asking this question still depends on making reliable distinctions. Nietzsche must distinguish the questions his predecessors asked from those they avoided. His inquiry creates a difficulty for itself: how can it assess truth's value while continuing to value accuracy in its own account? Keep that difficulty open.

An opposition may conceal a shared history

§2 gives a voice to the metaphysician who refuses to let something highly valued arise from something condemned. Truth must have an origin entirely separate from error; selflessness must be free of self-interest. The movement from a ranking to an account of origins is the target.

Nietzsche proposes that the apparent opposites may be connected. A capacity we admire might develop through impulses we dislike. The possibility challenges the demand for a pure origin, but possibility alone does not establish any particular history. His repeated qualifications invite an investigation that must still do its work.

§3 extends the question into thinking itself. Conscious reasoning may be directed by drives and by requirements of a particular form of life. Even a preference for certainty can express such requirements. The passage asks us to examine the supposedly sovereign activity of reason as something embodied and interested. It does not provide an experiment proving every motive Nietzsche attributes to philosophers.

A useful error remains an error

§4 separates a judgment's falsity from its value for life. Nietzsche suggests that basic practices of thought depend on simplifications and fictions. He includes logic, number, and judgments that claim necessity independently of experience. His claim reaches deeper than the ordinary observation that a comforting belief can help someone endure a difficult day.

Consider, as an analogy, a map that omits almost everything in a landscape so that a traveler can navigate it. Its usefulness depends on selection. This illustrates why exhaustive representation and usefulness differ; it does not prove Nietzsche's stronger claim that indispensable judgments are false. A selective account can also be accurate for a stated purpose.

Separate three issues: whether a judgment is true, what it enables, and whether its effects justify maintaining it. Nietzsche's emphasis on preservation and cultivation supplies evaluative priorities that need their own examination. A useful deception does not become true because someone benefits from it; benefits to one person may impose costs on another.

The philosopher as an advocate who conceals the brief

§5 accuses philosophers of presenting arguments found after the fact as though impersonal reasoning produced their commitments. His complaint concerns honesty about intellectual advocacy. He attacks Kant and Spinoza through caricatures of their styles as well as their claims. These attacks reveal his suspicion; they cannot replace a fair examination of either philosopher's arguments.

§6 broadens the diagnosis: a philosophy can disclose the organization of its author's drives and the values that organization seeks to establish. Nietzsche's distinction between philosopher and scholar matters here. He allows that a scholar's specialized inquiry may function relatively independently of the interests governing the rest of that person's life. His claim is not simply that every calculation conceals the same kind of moral purpose.

Ask two questions together: what does this argument establish, and why does establishing it matter to this thinker? Discovering a motive does not make the argument invalid. But an argument's validity on a limited question may leave the larger choice of questions and purposes unexplained.

Whose values have been discovered in nature?

In §9 Nietzsche challenges the Stoic injunction to live according to nature. On his portrayal, nature is indifferent to the standards through which Stoics organize their lives. Their alleged discovery of an authoritative natural order becomes a projection of their own ideal.

He then generalizes: philosophy shapes an image of the world through its commanding, creative impulse. This is an early appearance of will to power in the book. It concerns philosophical interpretation here; Reading 2 will examine how far Nietzsche tries to extend the idea.

The generalization turns back on its author. Nietzsche also describes nature and judges ways of living. If a philosophy expresses its creator's values, what warrants his description? A promising response would identify assumptions, supply reasons, and expose an interpretation to competing accounts. Simply announcing one's perspective cannot settle the competition.

The opening thus prepares two connected inquiries: what governs our thinking, and what could make its governing values defensible? The course will follow both through religion, morality, scholarship, honesty, politics, and rank.

A difficulty to keep in view

Does explaining a belief through its motives explain it away?

It can be tempting to hear an accusation of self-interest as a refutation. Yet a person can desire a conclusion and also offer good reasons for it. To assess those reasons, we must examine the argument and its evidence.

Motives still matter when they direct attention, suppress objections, or determine which outcomes count as valuable. Nietzsche's inquiry becomes strongest when it shows how those effects occur in a particular case. It becomes weaker when suspicion substitutes for demonstration.

Apply the same distinction to your enthusiasm or resistance as a reader. Neither liking Nietzsche nor distrusting him establishes whether a particular claim is right. Each reaction can identify something worth examining.

Check your understanding

Try answering before revealing each suggested response.

What should I write in my notes?

Return to your two sentences about honesty. Write 250–350 words separating the following questions.

1. What do you mean by honesty: accurate disclosure, sincere self-examination, or a commitment to inquiry? Choose one concrete case.
2. What might explain your attachment to it? Mark speculation about motives as speculation.
3. What does honesty make possible in this case, and who could bear its costs?
4. Give a reason for valuing it that survives the possibility of a mixed or unattractive origin. Name one circumstance that would test your reason.

Keep this response. Reading 8 returns to honesty as a virtue, and Reading 10 asks you to reconsider it through the book's accounts of discipline, creation, and rank.

Continue the reading

The next reading examines the thinker and the will that seem to stand behind these valuations. Carry forward one question: how much have we already assumed when we say that I think or I will?
