Overview

On 26 August 1898 William James stood up before the Philosophical Union at Berkeley and said that a principle he had heard Peirce state in Cambridge in the early 1870s deserved a name. The name was pragmatism; James put it into print for the first time, credited the coinage to Peirce himself, and directed his audience to an article printed twenty years earlier in Popular Science Monthly. This is that article. It came out in January 1878, the second of six, under a byline that gave Peirce's day job — assistant in the United States Coast Survey. The word pragmatism appears nowhere in it. Instead it offers a rule, arrived at by way of a stale piece of textbook furniture. For two centuries logicians had been sorting ideas into clear and obscure, distinct and confused, on a scheme Peirce traces to Descartes and then to Leibniz; he calls the distinctions an antique fit for a cabinet of curiosities, and proposes a third and higher grade of clearness. Consider what effects, conceivably bearing on practice, the object of your conception could have. Your conception of those effects is the whole of your conception of the object. Applied to hardness, the question whether an untested diamond is hard turns out to be a question about how we arrange our language. Applied to truth, the rule yields the formulation the rest of Peirce's philosophy hangs from: the true is the opinion that investigation is fated to end in, and the real is whatever that opinion is about. James went on to build something Peirce disliked, and misremembered having seen the word pragmatism in this paper. In April 1905 Peirce renamed his own version pragmaticism.

Key concepts

What exactly is the rule this paper proposes?

Consider what effects, conceivably bearing on practice, you take the object of your conception to have; your conception of those effects is the whole of your conception of the object. That is the entire rule. It offers no test of truth and no method of discovery — it says only what a conception amounts to once it is stated.

Where do 'clear' and 'distinct' come from, and why retire them?

From Descartes, who made clearness the mark of truth, and from Leibniz, who added distinctness — being able to state a definition. Two centuries of logic textbooks sorted ideas by that pair. Peirce calls it an antique fit for a cabinet of curiosities, because a man can define a term perfectly and still have no grip on what it means.

Why does Peirce insist on "conceivable" effects rather than actual ones?

Because a conception lies in effects conceived, not observed: hard means not scratched by many other substances. Yet in 1878 he stopped short at the untested case. A diamond crystallised in cotton and burned before anything pressed it could, he says, be called soft without falsity; that concerns the arrangement of our language. In 1905 he retracted this as a lapse into nominalism.

Why does the paper spend so long on the idea of force?

Because force is the test case. Generations had asked what force is in itself and got nowhere; Peirce shows that everything anyone knows of it is contained in how accelerations compound. Once the rule is applied, a famous obscurity turns out to be an obscurity about nothing, and he promises the same treatment for other metaphysical puzzles.

Does the word 'pragmatism' appear anywhere in this article?

No — nowhere in it. Peirce had used the word in conversation in Cambridge years earlier, but William James put it into print in 1898, credited the coinage to Peirce and sent his audience to this article. James then built something Peirce disliked, and in 1905 Peirce renamed his own version in order to get it back.

Themes of the book

What this book returns to, gathered into themes and ordered by how much of the text each one occupies.

A Conception Is Its Practical Effects

Ask what effects with a conceivable bearing on practice the object of your idea could have; your conception of those effects is the whole of your conception of the object. The rule arrived twenty years before the word.

Clear and distinct had been sorted by logicians for two centuries on a scheme running from Descartes to Leibniz, and Peirce retires the pair as a cabinet curiosity before proposing a third grade of clearness above them. The test bites at once: whether an untested diamond is hard turns out to be a question about how we choose to speak, not about the stone. James named the principle pragmatism, built something else on it, and Peirce eventually renamed his own version pragmaticism.

Truth as the Opinion Fated to Come

Turn the practical rule on truth itself and truth stops being a correspondence available for inspection: it becomes the destination of inquiry, with reality defined as whatever that destination is about.

Opinion and object change places. The real does not certify an investigation; the investigation, carried far enough by whoever cares to pursue it, converges, and the real is what it converges on. The convergence belongs to the community rather than to any inquirer who will live to see it. The rest of Peirce's philosophy hangs from this formulation, and every later quarrel with the pragmatists turned on whether they had kept it.

Works held

The author's work in order, this book marked in place. Your-language title first, the original beneath it where the two differ; side chips show which full texts are held.

  1. 1867 On a New List of Categories

    The earliest item on this shelf, and the root of everything after it: the three-part scheme of quality, relation and representation reappears in the logic papers of 1877–78 and again in the evolutionary cosmology of the 1890s.

    EN
  2. 1868 Questions Concerning Certain Faculties Claimed for Man

    Where Peirce clears the ground. The four denials reached here — no intuition, no introspection, no thought without signs, no conception of the incognizable — are restated as premisses at the head of the sequel.

    EN
  3. 1868 Some Consequences of Four Incapacities

    The sequel, and where the argument arrives. The preceding article asked whether we have certain faculties; this one takes its four denials as premisses and follows them out to a theory of reality and of the self.

    EN
  4. 1877 The Fixation of Belief

    Written for readers with no philosophy behind them: the first instalment of a six-part course in the logic of science, serialised in a general-interest monthly. Everything the other 1877–78 papers do rests on the account of doubt, belief and inquiry set out here.

    EN
  5. 1878 Deduction, Induction, and Hypothesis

    The paper that ends the series. Its central idea — guessing, treated as an inference with rules of its own rather than as a lack of them — is what Peirce kept working at for the rest of his life.

    EN
  6. 1878 How to Make Our Ideas Clear you are here EN
  7. 1878 The Doctrine of Chances

    Third in the series, and the point where the account of inquiry acquires a price. Half of it is arithmetic — card packs, whist hands, insurance offices — and the other half asks whether a creature who never lives to complete a run of trials may reason from probabilities at all.

    EN
  8. 1878 The Order of Nature

    The religious instalment of the 1877–78 series. It reaches forward to the essay Peirce published at the end of his life: both ask what a scientific habit of mind is entitled to say about God, and they give different answers.

    EN
  9. 1878 The Probability of Induction

    A general magazine's readers are asked here to check a table of black and white balls for themselves. It is the most technical stretch of the 1877–78 series, and the one that takes on the probability textbooks directly.

    EN
  10. 1891 The Architecture of Theories

    A prospectus rather than a treatise, and the first of the five articles of Peirce's metaphysical series in Paul Carus's Monist, 1891–93 — the run in which the cosmology it sketches was built.

    EN
  11. 1892 Man's Glassy Essence

    Three things that do not obviously belong together — the constitution of matter, the chemistry of living tissue, and the question whether a church or a crowd can think — joined by the argument that mind and matter differ only in which side you look from.

    EN
  12. 1892 The Doctrine of Necessity Examined

    It stands second in the series, and it is the one that started a quarrel: Carus attacked it twice in his own journal and Peirce defended it once, so that the argument about chance occupied The Monist for fifteen months.

    EN
  13. 1892 The Law of Mind

    Where tychism acquires its partner. The chance of the April paper needed continuity to work in, and continuity gets its name and its defence here — the idea Peirce came to regard as the one his philosophy could least do without.

    EN
  14. 1893 Evolutionary Love

    Here the cosmology turns into an argument about how people ought to live: chance, necessity and love applied to the history of ideas, and to the ethics of a commercial century. It closed the Monist series.

    EN
  15. 1893 What is Christian Faith?

    Addressed past the theologians to two audiences at once — churchmen keeping their membership narrow, and the scientifically educated, shut out of the churches, who were talking about founding one of their own.

    EN
  16. 1899 Leibniz Rewritten

    The one book review on this shelf, from the years after the Coast Survey when Peirce lived partly by notices and dictionary work. It is the only piece here in which he is weighing someone else's system rather than building his own.

    EN
  17. 1908 A Neglected Argument for the Reality of God

    Thirty years after the logic papers and fifteen after the cosmology, Peirce turns the machinery of hypothesis on the question the 1878 series had left open.
