"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. Wittgenstein's first philosophy was a Schopenhauerian neo-Kantianism, and although he soon rejected much of the substance of Schopenhauer's work, his problems remained closely connected with Schopenhauer's view of the world and man's relation to it. Wittgenstein's early philosophy is a departure from Schopenhauer - a rigorously purified form, so to speak, of Schopenhauer's "World as Will and Representation". In "Pulling up the Ladder", Brockhaus explains Schopenhauer's system of the world as Will and Representation, then proceeds to investigate Frege's realism and Hertz's conventionalistic philosophy of science - two of the elements which fuelled Wittgenstein's purification of Schopenhauer. Brockhaus analyzes the relations between the "Tractatus" and Russell's treatment of Incomplete Symbols and Logical Types. He investigates two Schopenhauerian issues which present difficulties for the Wittgensteinian world-view: the principles of mechanics and the propositional attitudes which bring the ego into the world. The final chapters examine the metaphysical ego and its relaxation to value, employing Wittgenstein's metaphor of "my world", since "my world" is permeated by the metaphysical ego, the Schopenhauerian World as Will emerges anew, albeit in a curiously ineffable form.
