Several authors have detected profound analogies between Kant and Wittgenstein. Their claims have been contradicted by scholars, such being the agreed penalty for attributions to authorities. Many of the alleged similarities have either been left unsubstantiated at a detailed exegetical level, or have been confined to highly general points. At the same time, the ‘scholarly’ backlash has tended to ignore the importance of some of these general points, or has focused on very specific issues or purely terminological matters. To advance the debate, I distinguish four different topics: questions of actual influence; parallels at the methodological level; substantial similarities in philosophical logic; substantial similarities in the philosophy of mind. The article concentrates on the second and third topic. Section I argues that the critical conception of philosophy shared by Kant and Wittgenstein is itself due to the fact that they explain the a priori status of necessary propositions by reference to the way we experience or represent reality. Section II shows how the Tractatiis linguistically transforms this ‘reflective turn’, replacing Kant's preconditions of experience by preconditions of symbolic representation. Section III suggests that this explanation of the a priori involves the idea of an isomorphism between thought and reality, and that both Kant's transcendental idealism and Wittgenstein's early metaphysics of symbolism distort this isomorphism. Wittgenstein later rejected this metaphysics of symbolism, on the grounds that language is autonomous, and section IV detects parallels between that idea and Kant's ‘diallelus’ argument against the correspondence theory of truth. Finally, I claim that while Wittgenstein is right to insist that all a priori propositions are conceptual, Kant, in calling them synthetic a priori, is right to deny that they simply unpack the concepts involved in the propositions themselves.

This unique study brings together for the first time two of the most important philosophers of this century. Never before have these two thinkers been compared - and commentators' opinions on their relationship differ greatly. Are the views of Wittgenstein and Quine on method and the nature of philosophy comparable or radically opposed? Does Wittgenstein's concept of language engender that of Quine, or threaten its philosophical foundations? An understanding of the similarities and differences between the thought of Wittgenstein and of Quine is essential if we are to have a full picture of contemporary philosophy. This collection of essays offers diverse and original ways in which to view their relationship.

In §§89-133 of the Philosophical Investigations Wittgenstein appears to reject the traditional view that philosophy is a cognitive discipline, that is, one that could result in knowledge expressed in true propositions. No part of the Investigations has caused more irritation. Often Wittgenstein’s attitude is understood as a rejection of science and an expression of a deep-rooted irrationalism. But, I shall argue, this reaction is misguided. For whilst it is true that Wittgenstein was personally hostile towards the scientific spirit of the age (CV pp. 6-7), this ideological attitude can be separated from his methodological position. The latter does not condemn science but scientism, the imperialist tendencies of scientific thinking. Wittgenstein insists that philosophy cannot adopt the tasks or methods of science (cf. e.g. CV p. 16).

Do animals have minds? We have known at least since Aristotle that humans constitute one species of animal. And some benighted contemporaries apart, we also know that most humans have minds. To have any bite, therefore, the question must be restricted to non-human animals, to which I shall henceforth refer simply as "animals." I shall further assume that animals are bereft of linguistic faculties. So, do some animals have minds comparable to those of humans? As regards that question, there are two basic stances. Differentialists maintain that there are categorical differences separating us from animals; assimilationists hold that the differences are merely quantitative and gradual (see Brandom 2000, pp. 2–3). This paper only deals with one kind of mental phenomenon, namely intentional states such as believing, desiring, and intending. I shall also refer to these as having thoughts or thinking rather than as "propositional attitudes," since that terminology is misguided. My primary target is a variant of differentialism, namely lingualism. It maintains that animals lack intentional states such as beliefs, desires, and intentions, since, on a priori conceptual grounds, the latter require language. The term "language" is here confined to public languages, notably natural languages, and excludes inner symbolisms such as the language of thought postulated by many cognitive scientists.

Ludwig Wittgenstein crossed the second Styx, from living memory to history, during the years since the present century began. He is recognized today as one of the most original and powerful thinkers of the twentieth century, and his work belongs to the body of literature philosophers will read and interpret afresh in each generation, for as long as the European intellectual tradition survives. He wrote nothing in political philosophy or jurisprudence, very little in ethics, and the only sustained record of his philosophical ideas about religion and art consists in notes taken by students at his lectures. The Tractatus was published in 1921. In this book, Wittgenstein argues that the logical form of a proposition is utterly different from its superficial grammatical form. The greatest obstacles to understanding Wittgenstein's philosophy are not any inherent obscurity in his ideas, but the aphoristic style in which he wrote and the introverted character of his thought.

The most comprehensive survey of Wittgenstein’s thought yet compiled, this volume of fifty newly commissioned essays by leading interpreters of his philosophy is a keynote addition to the Blackwell series on the world’s great philosophers, covering everything from Wittgenstein’s intellectual development to the latest interpretations of his hugely influential ideas. The lucid, engaging commentary also reviews Wittgenstein’s historical legacy and his continued impact on contemporary philosophical debate.
