 Protagoras and relativism

Show Summary Details


In the Theaetetus, Plato attributes to Protagoras a position that contains elements of both relativism about truth and infallibilism. On the one hand, he takes Protagoras to be proposing an infallibilist epistemology, not a theory of relative truth: Protagoras’ thesis is that everyone is always correct concerning what is true. On the other hand, when Plato sometimes describes Protagoras’ measure doctrine in terms of what is ‘true for’ a person, he does so because on the theory he develops for Protagoras to support this thesis, all properties are to be relativized, including truth.
