This volume brings into focus the unique philosophical and historical importance of Wittgenstein's pre-Tractatus writings. These contributed essays show that Wittgensteinâs earliest writings are worth studying for their own sake. They also reveal how much one can still learn about the Tractatus, if we are to study these early writings not as documenting oneâs prior interpretation of the Tractatus, but as a series of steps in Wittgensteinâs thought, some down paths that are later abandoned, some leading towards it. The volume thus offers not only a fresh perspective on the pre-Tractatus writings, but also a comprehensive reading of a wide range of central topics from the very first letters, the âNotes on Logicâ, the âNotes dictated to G.E. Mooreâ to the three surviving war-time notebooks
