Ethics & Cynic Foundations
Antisthenes
445 BC – 365 BC
“Virtue is sufficient for happiness; it requires nothing else beyond Socratic strength.”
Devoted pupil of Socrates and the intellectual founder of Cynicism. Antisthenes argued that virtue alone constitutes happiness, that conventional goods are indifferent, and that the philosopher must achieve self-sufficiency above all.
Biography
Antisthenes (c. 445–365 BC) was an Athenian philosopher who first studied under the sophist Gorgias before becoming one of Socrates' most devoted followers. He founded a school at the Cynosarges gymnasium in Athens.
Antisthenes radicalised Socratic ethics: if virtue is sufficient for happiness, then wealth, pleasure, and social status are not merely less important than virtue — they are positively dangerous. The virtuous philosopher needs only virtue and the strength to live by it.
He also developed an early theory of predication: only identical statements are strictly true (e.g., 'man is man'), and all cross-predicative statements are problematic. This logical position provoked Aristotle's sustained critique. His practical ethics were taken further by his student Diogenes of Sinope, who became the paradigmatic Cynic.

Key Takeaways
- Virtue alone is sufficient for happiness; all conventional goods are indifferent or harmful.
- The philosopher must cultivate autarkeia — radical self-sufficiency and independence.
- Pleasure is not a good; Antisthenes preferred madness to pleasure.
- Logical nominalism: only tautological predications are strictly true.
- Founded the ethical tradition that became Cynicism, which in turn influenced Stoicism.
