American philosophy holding that an idea's meaning and truth lie in its practical consequences, in the difference it makes.
See it on the Philosophy map →The idea
The idea: to understand a belief, ask what difference it would make in experience if true. Peirce stated it in 1878; William James popularized it from 1898, saying true ideas 'work'; John Dewey treated ideas as problem-solving tools. James's example: does a man circling a tree 'go round' a squirrel that keeps to the far side of the trunk? It depends what practical meaning you give 'round.' Main objection: Bertrand Russell argued usefulness is not truth; false beliefs can work.
Why it matters
It gave America its distinctive philosophy, shaped law, education and science, and revived after 1970 through Richard Rorty, Hilary Putnam and others.
Think of it like
Like due diligence: a claim about a property means what you could check, rents collected, roof inspected, permits on file.
Where it comes from
Peirce's 1878 essay, James's 1898 Berkeley lecture and his book Pragmatism (1907), Dewey's many works, and letters among the founders.
Still debated
Whether pragmatism has a coherent theory of truth: is truth what works now, what inquiry would eventually agree on, or something else?

▸Charles Sanders Peirce founded PragmatismWell documented
The connection
In discussions at the Metaphysical Club, Peirce proposed his 'pragmatic maxim': to clarify any idea, list the practical effects its object could have; that list is the idea's whole meaning. He took the name from Kant's word pragmatisch. William James later credited him publicly, launching pragmatism as a movement.
When and how
Cambridge, Massachusetts, early 1870s, with William James and Oliver Wendell Holmes Jr.; published as 'How to Make Our Ideas Clear,' Popular Science Monthly, January 1878.
How we know
The 1878 essay, James's 1898 Berkeley lecture naming Peirce as founder, and Peirce's 1905 account of the term's origin.
Debates and open questions
Whether James's movement was really Peirce's: the word reached print only in 1898, and Peirce renamed his own view 'pragmaticism,' 'ugly enough to be safe from kidnappers.'
▸William James popularized PragmatismWell documented
The connection
Peirce coined pragmatism as a method for clarifying ideas, but few read him. James gave it a public voice: a famous 1898 lecture credited Peirce and launched the word, and his bestselling Pragmatism (1907) presented truth as what works in experience. He widened it from a theory of meaning into a philosophy of life and religion.
When and how
His Berkeley lecture 'Philosophical Conceptions and Practical Results' (1898), and the Pragmatism lectures at the Lowell Institute in Boston and at Columbia, 1906–07.
How we know
The lecture and book are published, and the term's public spread is traced to them.
Debates and open questions
Peirce disliked James's looser version and renamed his own view 'pragmaticism', a word 'ugly enough to be safe from kidnappers'.
▸Pragmatism influenced W. V. O. Quine, "Two Dogmas of Empiricism"Mostly agreed
The connection
Quine ended 'Two Dogmas' by calling his view 'a more thorough pragmatism': we revise our web of beliefs by what works best for predicting experience. Like Peirce and Dewey, he treated knowledge as continuous with science and denied that any truths are fixed in advance of experience.
When and how
Harvard, where William James had taught; the last section of 'Two Dogmas' (1951) credits Carnap and C. I. Lewis with pragmatism about choosing frameworks, then pushes it further.
How sure are we?
The paper's own wording, and Quine's later essay 'The Pragmatists' Place in Empiricism' (1981). He said he owed more to Carnap, so the exact debt is uncertain.
Debates and open questions
Whether Quine belongs in the pragmatist tradition or was a scientific empiricist borrowing its vocabulary is debated by historians of American philosophy.
▸Pragmatism was carried into schools and politics by John Dewey: democracy, education and inquiryWell documented
The connection
Dewey turned pragmatism into 'instrumentalism': ideas are tools for solving real problems, tested by results. He applied this to schools, founding a Laboratory School to teach by doing, and to politics, arguing democracy is a way of life built on shared inquiry, not just voting. Democracy and Education (1916) became his best-known statement.
When and how
University of Chicago, Laboratory School founded 1896; Columbia University, New York, from 1904; he also lectured in Japan and China in 1919–21.
How we know
His books, the Laboratory School's records and continuing existence, and the progressive education movement that cited him.
Debates and open questions
Whether 'progressive education' carried out or distorted his ideas; he criticized child-centered excesses in Experience and Education (1938).
