Both in ethics and in epistemology one source of scepticism in its contemporary version is the realization, often belated, of the full consequences of atheism. Modern non-moral philosophy looks back to Descartes as its father figure, but disowns the Third Meditation. But if God does not underwrite one's cognitive powers, what does? The largely unknown evolution of them, which is just a version of Descartes’ unreliable demon? “Let us … grant that all that is here said of God is a (...) fable, nevertheless in whatever way they suppose that I have arived at the state of being that I have reached, whether they attribute it to fate or to accident, or make out that it is by a continual succession of antecedents, or by some other method — since to err and deceive oneself is a defect, it is clear that the greater will be the probability of my being so imperfect as to deceive myself ever, as is the Author to whom they assign my being the less powerful”.

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.
