People do, quite naturally and not uncommonly, speak of other people as deceiving themselves, as being their own dupes. A man's child is ill and growing constantly worse. The father keeps talking optimistically about the future, keeps explaining away the evidence, and keeps pointing to what he insists are signs of improvement. We can easily imagine ourselves deciding that he has deceived himself about his son's condition. Nor is it the case that talk of self-deception is appropriate only in connection (...) with other people. We can easily imagine the father admitting, say, after the son's death, that he has deceived himself about the child's condition. Thus the notion of self-deception obviously has application. Furthermore, ordinarily talk of self-deception is not thought to be puzzling. (shrink)

In his paper “The Meaning of a Word” J. L. Austin argues that a set of questions and a set of answers to these questions is nonsensical. The philosophical claim that a question or answer is nonsense is an important part of the philosopher's stock and trade; for to ask and to propose answers to nonsensical questions is to reveal confusion and the tracking down and unraveling of confusion is one of the valuable contributions that philosophy has to make in (...) the advancement of understanding.At the same time one must not accept too easily the charge that a question or a form of answer to a question is nonsensical, for to do this is to block off a whole avenue of inquiry and therein direct one's efforts away from a route that might yield positive results.
