Stoicism

An ancient philosophy whose most famous surviving text was written by a Roman emperor, purely as private notes to himself, never originally intended for anyone else to read.

Cheat Sheet

  • Stoicism is an ancient Greek philosophy, later widely practiced in Rome, centered on the idea that a good life comes from living in accordance with reason and virtue rather than chasing external circumstances.
  • A core Stoic principle is the distinction between things within our control (our own judgments and actions) and things outside our control (external events and other people's actions) — focusing energy only on the former.
  • Prominent Stoic philosophers include Epictetus, a former slave who became an influential teacher, and Marcus Aurelius, a Roman emperor whose personal reflections, "Meditations," remain widely read today.
  • Stoicism holds that negative emotions primarily stem from mistaken judgments about what's genuinely good or bad, rather than from external events themselves.
  • Modern Stoicism has experienced a significant popular resurgence in recent years, particularly through self-help and personal development contexts drawing on ancient Stoic principles.
  • Contrary to the modern colloquial use of "stoic" to mean emotionless or unfeeling, actual Stoic philosophy emphasizes rational engagement with emotion rather than its complete suppression.

The Long Version

A Philosophy Built Around Reason and Virtue

Stoicism originated in ancient Greece before becoming particularly influential in Rome, built around the central claim that living a genuinely good life comes from cultivating reason and virtue, rather than from chasing after external circumstances like wealth, reputation, or pleasure, which Stoics considered ultimately outside a person's true control and therefore unreliable foundations for genuine wellbeing.

The Dichotomy of Control

Perhaps Stoicism's most practically influential concept is the dichotomy of control, the sharp distinction between things genuinely within our control, namely our own judgments, choices, and actions, and things outside our control, including external events and other people's behavior. Stoic philosophy counsels focusing one's energy and concern exclusively on the former, since attempting to control the latter is considered both futile and a significant source of unnecessary distress.

From a Former Slave to a Roman Emperor

Stoicism's most influential surviving voices span a remarkably wide range of life circumstances: Epictetus, born into slavery before eventually gaining his freedom and becoming a highly influential Stoic teacher, and Marcus Aurelius, a Roman emperor whose private personal reflections, later compiled as "Meditations," were never originally intended for publication yet remain among the most widely read philosophical texts today.

Emotion, Judgment, and Stoicism's Modern Revival

Contrary to the modern colloquial use of "stoic" to describe someone emotionless or unfeeling, actual Stoic philosophy holds that negative emotions arise primarily from mistaken judgments about what's genuinely good or bad, rather than counseling the complete suppression of emotion itself, encouraging instead a more rational, examined relationship with one's own reactions. This distinction has become especially relevant amid Stoicism's significant recent popular resurgence, particularly within self-help and personal development contexts drawing directly on these ancient principles.
