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... [U]nlike the sophist, he can use parrhesia and speak freely because what he says accords... with what he thinks... [which] accords... with what he does.
