Antisthenes vs Diogenes of Sinope vs Zeno of Citium

Antisthenes, Diogenes of Sinope, and Zeno of Citium form the philosophical lineage from Socrates through the Cynics to the founding of Stoicism. Antisthenes was a student of Socrates; Diogenes claimed to be a student of Antisthenes (the connection is disputed); Zeno studied with the Cynic Crates before founding his own school in Athens. The three represent the radicalization of the Socratic ethical project and its later domestication into a systematic philosophy.

Where they agree

All three held that virtue is sufficient for happiness, all three rejected the conventional valuation of wealth, status, and political power, and all three treated philosophical practice as inseparable from a way of life. The Stoic doctrine that virtue alone is the good and that everything outside the rational use of one's faculties is indifferent has clear Cynic origins.

Where they disagree

Antisthenes developed the Socratic ethical inheritance into a doctrine that virtue is teachable and consists in self-mastery; he was suspicious of pleasure but did not reject civic life altogether. Diogenes radicalized the position: convention as such — Greek, civic, civilized — is the obstacle to natural virtue, and the philosopher should live in a wine jar and demonstrate natural life against social pretension. Zeno preserved the Cynic ethical core but reintegrated it with systematic philosophy: the Stoic sage is virtuous in the Cynic sense but lives within the cosmos as a rational whole, with developed doctrines in physics, logic, and ethics that the Cynics rejected as unnecessary.
