In “Socrates, Cynics and Flat-Nailed, Featherless Bipeds,” Nickolas Pappas describes two competing philosophical types that arose from the example Socrates set: sober Academics like Plato and mangy Cynics like Diogenes. “Philosophy has pulled in both directions, systematic and subversive, for as long as it has remembered Socrates. … The Academy had the originality to envision an intellectual society  … distinguished by the virtues of modesty and self-control, always ready to usher new students into the tradition. Philosophy as a tradition would have withered without an academy to live in. If it sometimes appears to be withering within the academy, that is because the subversive side of Socrates has its appeal: the virtues of the eccentric, above all eccentric courage, and the willingness to make your life an improvisation.”
