Overview

The belief that every event is precisely determined by law goes back, on Peirce's telling, to Democritus, who confined his attention to a field where nothing but mechanical constraint could show itself and then concluded that nothing else operates anywhere. Epicurus had to let the atoms swerve. The Stoics took the hard version and hardened it; the successes of mechanics made the hope of a wholly mechanical universe respectable; and by 1892 the doctrine had never been in greater vogue. To the necessitarians the paper puts a single question: what is the evidence? The commonest answer, that determinism is a postulate of scientific reasoning, gets short treatment — the answer of a man who comes to borrow money and, asked for security, replies that he postulates the loan. Observation cannot supply the evidence either, since no measurement has ever shown exact conformity to a law, and a probable inference can never establish that anything holds precisely and without exception throughout the universe. Meanwhile mechanism cannot account for the things we do observe: growth, increasing diversity, the sheer variety of the world, and consciousness, a patent fact and an inconvenient one. What Peirce offers instead is an element of absolute chance: minute departures from every formula that can be written, out of which the regularities we call laws have grown as habits. Three months later he christened the doctrine tychism. The paper ends by asking anyone who finds a flaw in the reasoning to point it out, privately or publicly. The journal's editor, Paul Carus, took the invitation: his rebuttal begins in The Monist on the page after Peirce's next instalment leaves off. Peirce replied at length in July 1893, and Carus answered him in the same number.

Key concepts

What is necessitarianism?

The doctrine that the state of things at any instant is completely determined by the state at any earlier instant, so that every event is fixed precisely by law. Peirce traces it to Democritus, notes that even Epicurus had to let the atoms swerve, and observes that by 1892 the doctrine had never been in greater vogue.

What does Peirce mean by 'absolute chance'?

Real spontaneity: minute departures from every formula that can be written, not merely variation we are too ignorant to predict. It is what he puts in the place of exact law, and what allows regularities to grow as habits rather than holding from the beginning. He gave the doctrine its name — tychism — only in the paper that followed.

Why doesn't measurement settle the question?

Because no observation has ever shown exact conformity to a law. Every measurement carries a range of error, and inside that range a tiny departure and a perfect fit look identical. A probable inference can establish that a formula holds closely and usually; it cannot establish that anything holds precisely and without exception throughout the universe.

What does Peirce say mechanism cannot account for?

Growth, increasing complexity, the sheer variety of the world, and consciousness. A mechanical universe conserves what it has and moves it about; it does not explain why there is more diversity now than there was. Peirce treats these as ordinary observed facts the doctrine leaves out, and calls consciousness a patent fact and an inconvenient one.

Isn't determinism simply a postulate that science has to make?

Peirce answers with the borrower who, asked for security on a loan, replies that he postulates the loan. A postulate is not evidence, and science does not need this one: inquiry proceeds by finding how closely formulas hold, which is what it does in any case. The question he keeps putting is what the evidence actually is.

Themes of the book

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

What Is the Evidence for Determinism?

The belief that every event is fixed precisely by law had never been in greater vogue, and one question is put to it: on what grounds? Neither observation nor methodological postulate turns out to supply any.

A man who comes to borrow money and, asked for security, replies that he postulates the loan — that is the answer that determinism is a presupposition of scientific reasoning. Measurement fares no better, since no observation has ever shown exact conformity to a formula and probable inference cannot establish that anything holds without exception everywhere. Meanwhile growth, increasing diversity and consciousness go unexplained. In their place Peirce puts absolute chance, minute departures from every law, out of which regularities grew as habits.

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

    The second instalment of the 1877–78 series, nominally about a dead distinction in the logic textbooks. Two decades after it was printed, the American pragmatists took it as their charter.

    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 you are here 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.
