This book offers a new interpretation of Wittgenstein's Tractatus and connects it with the early development of analytic philosophy in Cambridge and Jena. In this book, Wittgenstein's method is presented as an epitome of analytic philosophy. It considers how Wittgenstein adopted and deepened the method of Moore and Russell and how he fused it with that of Frege. The book also explores the attempts to adopt Wittgenstein's method by the Vienna Circle, the Cambridge school of therapeutic analysis, and the Oxford school of ordinary language philosophy, as well as how it relates to some leading figures in the history of philosophy including Kant and Spinoza. The Tractatus, Wittgenstein's Method and Analytic Philosophy is essential reading for all scholars, researchers and advanced students of the thought of Ludwig Wittgenstein and of the history of analytic philosophy. Nikolay Milkov is Professor of Philosophy at Paderborn University, Germany. His most recent previous book is Hermann Lotze's Influence on Twentieth Century Philosophy (2023).
