A. C. Grayling

The ten essays gathered together in this book treat of truth, meaning, realism, natural kind terms, and related topics. Almost all began life as invited contributions to conferences. From the Preface we learn that Grayling, in contrast to those colleagues whose perfectionism leads them to publish too little, preferred to ‘venture ideas as if they were letters to friends’. The style could hardly be called epistolary, however; a high level of generality is maintained throughout, and there is much plotting of the relationships between philosophical positions. An aesthetic of tentativeness also prevails: at one point, for example, Grayling withdraws his too hasty offer of a sketch of an argument, in favour of ‘a sketch of how an argument might look in outline’. A sketch of a sketch, perhaps?Things are not so sketchy that one cannot discern some positive claims. One of these is embodied in what …

Within the history of western philosophy, there have been a number of classic ways of arguing for the existence of God. The most important of these are the teleological argument, the ontological argument, the cosmological argument, the moral argument, and a loose family of pragmatic considerations affirming the prudence or desirability of theistic belief. Demonstrating the weaknesses of these approaches is crucial for establishing the ‘negative’ case for atheism. This essay begins by defining what it is that philosophers normally means by ‘God’—i.e., what it is that the classic arguments in the philosophy of religion are arguing about. It then outlines and critiques each main approach in turn, focusing primarily on its most classic and influential expressions within the western philosophical tradition.

We have learned to be suspicious of the claim that a serious account of knowledge must begin at the Cartesian starting point, that is, with private data of consciousness serving as a basis for outward inferences to the world, these inferences proceeding on the security of one or another kind of epistemic collateral ranging from the goodness of a deity to the bruteness of the given. But the good reasons we have for dismissing the egocentric predicament as our motive for epistemology are not good reasons for dismissing a different predicament, one with which it is too often confused: namely, our finitary predicament, the fact that our powers of perception, memory and reason, even when co-operatively applied, are limited. For even if we are bound to conceive of general knowledge as the outcome of fundamental kinds of conceptual co-operation, the fact remains that our knowledge claims are underdetermined by the evidence we have for them; and that the framework, however collectively established, of what Quine calls our ‘immemorial theory’ of the world does not therefore protect particular knowledge-claims from defeasibility.

Ludwig Wittgenstein (1889-1951) was an extraordinarily original thinker, whose influence on twentieth-century thinking far outside the bounds of philosophy alone. In this engaging Introduction, A.C. Grayling makes Wittgenstein's thought accessible to the general reader by explaining the nature and impact of Wittgenstein's views. He describes both his early and later philosophy, the differences and connections between them, and gives a fresh assessment of Wittgenstein's continuing influence on contemporary thought.
