Overview

Stoicism teaches that virtue is the only true good, that the universe is governed by rational providence (Logos), and that wisdom consists in aligning one's will with nature. Founded by Zeno of Citium around 300 BCE, it became one of the most influential philosophies of the ancient world, guiding emperors and slaves alike toward equanimity in the face of fortune.

Key ideas

  • Virtue as the Sole Good: External circumstances — wealth, health, pleasure — are 'preferred indifferents.' Only virtue (wisdom, courage, justice, temperance) constitutes genuine good.
  • Dichotomy of Control: Distinguish what is 'up to us' (our judgments, intentions) from what is not (events, others' actions). Freedom and tranquility come from focusing only on what we can control.
  • Logos and Providence: The universe is governed by a rational principle (Logos). Everything that happens is part of a rational, deterministic order — the wise person embraces this with willing acceptance of fate.
  • Cosmopolitanism: All humans share in the universal Logos and are fellow citizens of the cosmos. Stoic ethics extends naturally to universal human dignity and brotherhood.
