Charles Taylor claims that ‘… human life is constituted by self-understanding,’ a self-understanding which is achieved in part by our capacity to use language. Because of this, the philosophy of language is important in Taylor’s philosophical views and central to these are his views on expression. I shall argue that one way to understand Taylor’s theory of expression is to place it within a theory of speech acts. And I shall try to show that this gives us a way to (...) interpret his contention that expression is a subject-related property and that there cannot be an objective science of it. Finally, I shall argue that Taylor’s grounds for the latter claim are defective and that this leaves open the possibility that there can be an objective science of expression. (shrink)
