This volume brings into focus the unique philosophical and historical importance of Wittgenstein's pre-Tractatus writings. These contributed essays show that Wittgenstein’s 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 one’s prior interpretation of the Tractatus, but as a series of steps in Wittgenstein’s 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 “Notes on Logic”, the “Notes dictated to G.E. Moore” to the three surviving war-time notebooks
