Böcker av Michael N. Forster

This book puts forward a much-needed reappraisal of Immanuel Kant's conception of and response to skepticism, as set forth principally in the Critique of Pure Reason. It is widely recognized that Kant's theoretical philosophy aims to answer skepticism and reform metaphysics--Michael Forster makes the controversial argument that those aims are closely linked. He distinguishes among three types of skepticism: "e;veil of perception"e; skepticism, which concerns the external world; Humean skepticism, which concerns the existence of a priori concepts and synthetic a priori knowledge; and Pyrrhonian skepticism, which concerns the equal balance of opposing arguments. Forster overturns conventional views by showing how the first of these types was of little importance for Kant, but how the second and third held very special importance for him, namely because of their bearing on the fate of metaphysics. He argues that Kant undertook his reform of metaphysics primarily in order to render it defensible against these types of skepticism. Finally, in a critical appraisal of Kant's project, Forster argues that, despite its strengths, it ultimately fails, for reasons that carry interesting broader philosophical lessons. These reasons include inadequate self-reflection and an underestimation of the resources of Pyrrhonian skepticism.

What is the nature of a conceptual scheme? Are there alternative conceptual schemes? If so, are some more justifiable or correct than others? The later Wittgenstein already addresses these fundamental philosophical questions under the general rubric of "e;grammar"e; and the question of its "e;arbitrariness"e;--and does so with great subtlety. This book explores Wittgenstein's views on these questions. Part I interprets his conception of grammar as a generalized (and otherwise modified) version of Kant's transcendental idealist solution to a puzzle about necessity. It also seeks to reconcile Wittgenstein's seemingly inconsistent answers to the question of whether or not grammar is arbitrary by showing that he believed grammar to be arbitrary in one sense and non-arbitrary in another. Part II focuses on an especially central and contested feature of Wittgenstein's account: a thesis of the diversity of grammars. The author discusses this thesis in connection with the nature of formal logic, the limits of language, and the conditions of semantic understanding or access. Strongly argued and cleary written, this book will appeal not only to philosophers but also to students of the human sciences, for whom Wittgenstein's work holds great relevance.
