The harmony between word and deed in Socrates' life is Dorian... manifested in the courage he showed at Delium. This harmonic accord... distinguishes Socrates from a sophist... who can give... fine and beautiful discourses on courage, but is not courageous... Unlike the sophist, he can use parrhesia and speak freely because what he says accords... with what he thinks... which accords... with what he does.
