Zeno of Citium

Zeno of Citium (c. 334–262 BCE) was a Greek philosopher who founded the Stoic school in Athens. His vision of philosophy emphasized living in harmony with nature, cultivating virtue, and practicing rational self‑control. Though none of his original writings survive, his ideas shaped centuries of thought and laid the foundation for Stoicism as a practical philosophy of resilience and ethical living.

Biography

Zeno was born in Citium, a city on Cyprus, around 334 BCE. After a shipwreck left him in Athens, he encountered philosophy and studied under Cynic and Megarian teachers. Inspired by Socratic ideals and the discipline of the Cynics, he developed his own system of thought. Around 300 BCE, Zeno began teaching in the Stoa Poikile (“Painted Porch”), a public colonnade in Athens. His followers became known as Stoics, taking their name from this setting. Zeno lived modestly, teaching that virtue was the only true good, and died in Athens around 262 BCE.

Indifference to externals: Health, wealth, and reputation are “indifferent” — neither good nor bad in themselves.

Discipline of desire and aversion: Train the mind to desire only what is good and avoid false judgments.
Practical philosophy: Philosophy is not abstract speculation but guidance for daily life.
