Philosophy, that most misunderstood of intellectual pursuits, is often mocked; and no part of philosophy is as often mocked as metaphysics. The image of the ‘speculative metaphysician’ dreaming up abstract pictures of the world has been held up for ridicule by poets, playwrights, novelists, journalists as well as by other philosophers. The Logical Positivists in the first half of the 20th Century rejected all metaphysical speculations as ‘meaningless’ since they could not be verified by scientific experiment; in the later part (...) of the century, Wittgenstein criticised systematic metaphysics as being a kind of intellectual disease resulting from our reading false pictures of the world into the grammar of our language. The common suspicion underlying many of these attacks is that ultimately, all metaphysics is a kind of nonsense, and that metaphysicians don’t really know what they are talking about. This suspicion is not new. Nicolas-Sébastien Chamfort commented in 1796, ‘I am tempted to say of metaphysicians what Scaliger used to say of the Basques: they are said to understand one another, but I don’t believe a word of it.’ Some contemporary philosophers may agree.

It can seem puzzling that there is such a thing as the philosophy of sense-perception. Psychology and the neurosciences study the mechanisms by which our senses receive information about the environment. So conceived, perception is a psychological and physiological process, whose underlying nature will be discovered empirically. Since few philosophers these days would presume to interfere with the empirical products of these sciences, the question arises as to the nature of philosophy’s distinctive role in the study of perception. There is (...) not a philosophy of digestion as there is a philosophy of perception; so what is it, exactly, that the philosophy of perception is supposed to do? (shrink)
