 This chapter serves as an introduction to the history and methodology of "doxography" as the deeply problematic means by which Presocratic texts have been transmitted and passed down to us.It highlights the importance of Diogenes Laertius, as one of the most brilliant early doxographers, and the ground-breakingDoxographiGraeci of the nineteenth century German classical scholar and philologist, Herman Diels.Like the sophists, Lacan questions the primacy of truth in both philosophical and psychoanalytic discourse, which is "relegated to the lowly status it deserves."
