Aristotle vs Diogenes of Sinope

Aristotle and Diogenes of Sinope represent two opposing models of what philosophy is for. Aristotle, the systematic philosopher of the Lyceum, treated philosophical inquiry as the patient pursuit of knowledge across every field; Diogenes, the founding Cynic, treated philosophy as a public performance of virtue against the conventions of civilized life.

Where they agree

Both inherited the Socratic concern with how a human being should live, both held that the good life is a matter of cultivating reason against the desires and conventions that obscure it, and both treated philosophical practice as inseparable from biographical example.

Where they disagree

Aristotle held that the highest human life is the contemplative life of the philosopher within a well-ordered city, sustained by external goods and political community. Diogenes rejected the city, conventional ownership, and conventional morality, treating philosophy as a discipline of voluntary deprivation and shameless candor. Where Aristotle saw philosophy continuing the work of civilization, Diogenes saw civilization as itself the obstacle to virtue.
