Strawson's attempt to refute scepticism about the existence of other minds has itself been a popular target of sceptical criticism. But the very persistence of the attacks suggests that no clinching rebuttal has yet been produced. One of the earliest and still one of the most effective responses to Strawson is Ayer's celebrated paper ‘The Concept of a Person’, in which he reasserts the position of classical empiricist scepticism on the existence of other minds. By reinterpreting and partly reconstructing Strawson's (...) arguments I shall try to show that the sceptical position represented by Ayer is indeed incoherent, as Strawson maintains, and I shall suggest why a conclusive rebuttal of Strawson's anti-sceptical arguments has not been and is unlikely to be produced.
