PERSON
Donald Davidson
The analytic philosopher who spent forty years asking what it takes for words to mean anything and thoughts to have content at all—and whose accounts of radical interpretation, the principle of charity, and the Swampman have become, unexpectedly, the most precise philosophical instruments available for asking whether a machine that talks actually means anything.
Donald Davidson is the philosopher of language and mind who, without intending to, produced the conceptual toolkit the age of artificial intelligence most needs. Born in 1917, trained at Harvard in classics before turning to philosophy, he wrote dense, careful essays with titles like "Truth and Meaning" and "Actions, Reasons, and Causes" that quietly restructured how his entire field thought about the relationship between words, the world, and the thoughts that words are supposed to carry. His central thought experiment—radical interpretation—asks how a field linguist could ever understand speakers of a completely unknown language with no shared vocabulary, no interpreter, and no bilingual informant, and finds that this extreme case is the general case: all understanding of another speaker is radical interpretation, an active construction governed by the assumption that the speaker is rational and largely right about the world.
