Show Summary Details


Does not directly advance the book’s argument, but prepares the ground by examining the ‘secret doctrine’ set up by Socrates in investigating the dialogue’s first serious definition, ‘Knowledge is perception’. Its key components are the relativist thesis of Protagoras that ‘Man is the measure of all things’, and the doctrine associated with Heraclitus and others that everything is in flux.

Keywords: flux; Heraclitus; knowledge; measure; perception; Protagoras; Protagoreanism; relativism
