Abstract

A main theme of this chapter is Ludwig Wittgenstein’s critical reception of Socrates in the 1930s, during which time Wittgenstein was developing a new philosophical methodology that he described as being antithetical to that of Socrates and best explained by way of this contrast. In particular, Wittgenstein is critical of an unexamined assumption relating to conceptual unity that seems to inform Socrates’ philosophical engagements, according to which one can always define a concept, or cases that fall under it, with reference to a feature or features common to all relevant cases. However, when accounting for Wittgenstein’s reception of Socrates, one needs to explain why the kind ofcritical remarks composed in the 1930s do not reoccur in Wittgenstein’s writings after this period, and why none of these critical remarks make it into his mature main work, the Philosophical Investigations. What made Wittgenstein change his mind about how to explain or introduce his later philosophy? My explanation is twofold: (i) Wittgenstein came to find his 1930s remarks on Socrates misleading for reasons connected with his rejection of philosophical theses and questions relating to the justification of philosophical methodology. (ii) Ultimately he came to recognize a possibility of reinterpreting Socrates’ method/s of employing definitions as consistent with his own methodology. Thus, rather than as an antithesis to Socratic philosophy, Wittgenstein’s later philosophy is better seen as giving it a new twist. Following this lead, I identify five important uses for definitions whose philosophical significance does not rest of the assumption of simple conceptual unity. Four of these are evidently present in Plato’s Socratic dialogues.
