Troubles about actions

In a recent, important series of papers,1Prof. Donald Davidson has proposed and illustrated a theory about theories of meaning. The theory, to put it very much more crudely than Davidson does, is simply that a theory of meaning for the (natural) language L ought to take the form of a truth definition for L. That is, such a theory ought to recursively associate each truth-valuable sentence of L with a representation of its truth conditions. Davidson says “what we require of a theory of meaning for a language L is that without appeal to any (further) semantical notions it place enough restrictions on the predicate ‘is T’ to entail all sentences got from schema [1] when ‘s’is replaced by a structural description of a sentence of L and ‘p’by that sentence.” (T & M 309)
