 A characteristic feature of Davidson’s approach to such ontological questions has been to focus on the logical structure of sentences about the entities at issue rather than on those entities as such. Davidson’s approach to events, for instance, is grounded in an analysis of the underlying logical form of sentences about events; in the case of causal relations, in an analysis of the logical form of sentences that express such relations (see ‘Causal Relations’ [1967a]); and in his approach to action also, Davidson’s approach involves an analysis of the logical form of sentences about actions (see ‘The Logical Form of Action Sentences’ [1967b]). This reflects a more general commitment on Davidson’s part to the inseparability of questions of ontology from questions of logic. This commitment is spelt out explicitly in ‘The Method of Truth in Metaphysics’ (1977) and it provides a further point of connection between Davidson’s work in the philosophy of action, event and mind and his work on questions of meaning and language.
