Donald Davidson

Early Life and Education

Donald Herbert Davidson was born on March 6, 1917, in Springfield, Massachusetts. He grew up in a cosmopolitan household and studied English, comparative literature, and classics at Harvard before turning to philosophy. He earned his Ph.D. at Harvard in 1949 under W.V.O. Quine, writing on Plato's Philebus. Quine's influence — particularly his holism about meaning and his skepticism about the analytic-synthetic distinction — remained a constant reference point in Davidson's work, though he departed from Quine in significant ways.

Theory of Action

Davidson's early major contribution was his theory of action, beginning with the landmark essay "Actions, Reasons, and Causes" (1963). Against the prevailing Wittgensteinian view that reasons for action are logically distinct from causes, Davidson argued that reasons (the agent's beliefs and desires) are causes of action. This seemingly simple thesis had profound implications: it reconciled the rational intelligibility of action with its causal explanation and established a framework for understanding practical reasoning that remains central to action theory.

Essays on Actions and Events (1980) collected these groundbreaking papers, including "The Logical Form of Action Sentences" (introducing events as a basic ontological category) and "Mental Events" (presenting anomalous monism).

Philosophy of Language: Truth and Meaning

Davidson's most influential idea in the philosophy of language was that a Tarskian truth theory can serve as a theory of meaning for natural languages. In "Truth and Meaning" (1967), he proposed that to give the meaning of sentences in a language is to provide a systematic theory that entails, for every sentence s of the language, a T-sentence of the form: "s is true if and only if p" — where p gives the truth conditions of s.

The radical innovation was that meaning could be theorized without positing meanings as entities. A theory of meaning is a theory of truth conditions, and understanding a language is grasping the systematic interconnections among the truth conditions of its sentences.

Davidson's approach to interpretation, developed in "Radical Interpretation" (1973) and other essays, held that the meanings of a speaker's utterances and the contents of her beliefs must be determined together, under the constraint of the "principle of charity" — the requirement that we interpret speakers as largely rational and largely right about the world. This makes meaning and belief holistic and interdependent.

Anomalous Monism

"Mental Events" (1970) presented anomalous monism: the thesis that every mental event is identical with some physical event, but there are no strict psychophysical laws connecting mental types to physical types. Mental events are physical (monism), but their descriptions under mental vocabulary do not reduce to physical descriptions (anomalous). This position attempts to reconcile the causal efficacy of the mental with the irreducibility of mental descriptions.

Later Work

In his later work, Davidson argued against the very idea of a conceptual scheme — a framework that organizes experience — in "On the Very Idea of a Conceptual Scheme" (1974), which has been called "the most important essay in contemporary philosophy." He argued that the dualism of scheme and content is incoherent, and with it, the forms of relativism that depend on it.

Davidson taught at Stanford, Princeton, Rockefeller University, the University of Chicago, and finally UC Berkeley. He died on August 30, 2003, in Berkeley, California.
