Pulling up the Ladder discusses how Wittgenstein's early philosophy became widely known largely through the efforts of Russell and other empirically-minded British philosophers, and to a lesser extent, the scientifically-oriented German-speaking philosophers of the Vienna Circle. However, Wittgenstein's primary philosophical concerns arose in a far different context, and failure to grasp this has led to many misunderstandings of the Tractatus. From Brockhaus' investigation of that context and its problems emerges this new interpretation of Wittgenstein's early thought, which also affords fresh insights into the later Wittgenstein.
