Is there such a thing as philosophical nonsense? For the best part of a century now philosophers have been accusing each other of talking nonsense. This practice presupposes that people can be wrong in thinking they mean anything by what they say, that there can be an illusion of meaning. But the assumption that illusions of meaning are possible has not, the author believes, been seriously examined; nor has the problem of how such illusions could be diagnosed been satisfactorily answered. (...) This book extends the work of a number of recent writers on Wittgenstein who have advocated an 'austere' view of nonsense, but in a more sceptical direction than they have taken. It argues that nonsensicalism is radically misguided and should be abandoned. The possibility that illusions of meaning occur outside philosophy - in dreams, in certain hoaxes, in madness or under the influence of drugs - is also examined. IAN DEARDEN read philosophy at Downing College, Cambridge, and Bedford College, London. He taught philosophy at Bedford College, the City University, the Polytechnic of North London and the University of Essex, and also for the London University Department of Extra-Mural Studies.
