Davidson has given us two theses: Tarski's format for truth definitions provides a format for theories of meaning and that the justification for a theory of language L as one of meaning is based upon the theory affording an informative interpretation of L-speakers. It will be argued, on the basis of a consideration of compositionality, that the Tarski format can indeed be re-jigged in line with . On the other hand, in opposition to , I shall commend a cognitive understanding of semantic competence under which interpretation is at best of marginal interest. In defence of this move, it will be argued that once compositionality and other commonly held constraints are recognised as being in fact empirical ones, then no principled distinction can be made between them and other constraints which militate against semantic competence being socially constituted

In recent years, a number of philosophers have argued against a biological understanding of the innate in favor of a narrowly psychological notion. On the other hand, Ariew ((1996). Innateness and canalization. Philosophy of Science, 63, S19-S27. (1999). Innateness is canalization: in defense of a developmental account of innateness. In V. Hardcastle (Ed.), Where biology meets psychology: Philosophical essays (pp. 117-138). Cambridge, MA: MIT.) has developed a novel substantial account of innateness based on developmental biology: canalization. The governing thought of this paper is that the notion of the innate, as it re-emerged with the work of Chomsky, is a general notion that applies equally to all biological traits. On this basis, the paper recommends canalization as a promising candidate account of the notion of the innate.
