Who really said it

The actions of men are the best interpreters of their thoughts

Based on words by John Locke 1632–1704 · English philosopher
Disputed Free to reuse

The thought comes from Locke’s Essay Concerning Human Understanding, Book I, chapter III, §3, in the inspected Gutenberg text. Locke actually begins, “I have always thought”; the compact sentence credited to Joyce is a grammatical recasting.

Fact-check

A Locke passage travels under Joyce’s name

The source predates Joyce and names a different author.

James Joyce

Wikiquote ↗ explicitly lists the saying as misattributed and identifies Locke’s Essay.

Credit Locke for the underlying passage and label the short sentence a recasting.

Context

Why it mattered

Locke is answering an objection to his rejection of innate moral principles. People’s conduct, he argues, is evidence of what they believe, and actual conduct varies too much to establish the universal agreement his opponents need.

The line became a general maxim when extracted from that argument. Its modern introductory “The actions” and added verb should be identified as a recasting, while the underlying passage should be credited to Locke.
