Philosophers have met with many problems in discussing the interconnected concepts being, identity, and truth, and have advanced many theories to deal with them. Professor Williams argues that most of these problems and theories result from an inadequate appreciation of the ways in which the words `be', `same', and `true' work. By means of linguistic analysis he shows that being and truth are not properties, and identity is not a relation. He is thus able to demystify a number of metaphysical issues concerning the meaning of the word `I', the relation between the mental and the physical, objects of thought, times and places, and the nature of reality. Williams presents his views clearly, with a minimum of technicality, and with rich and apt examples, so that they will be accessible to readers not versed in symbolic logic.
