Abstract

In raising the “What-is-F?” question, commentators disagree about whether Socrates is asking a conceptual question or a causal question. I argue that the contexts surrounding Socrates' two most prominent examples of adequate answers confirm that the “What-is-F?” question is a conceptual question in both the Meno and Euthyphro, but a causal question in the Laches and Protagoras. The “What-is-F?” question is multifunctional. Plato's Socrates consistently employs two separate vocabularies in connection with these two types of questions. By outlining their vocabularies, and by examining other important contextual signals, I pave the way for readers to distinguish between conceptual and causal investigation in the “dialogues of definition.”
