The Stoic Virtues

Living a life of virtue is the chief aim of Stoic philosophy. Zeno, the school’s founder, defined the entire goal of Stoic life as living in agreement with nature. Diogenes Laertius records the formula directly.

To the Stoics, virtue was never four separate qualities. It was one thing, right reason, considered under four different modes of action. What a person does falls into choosing, enduring, staying, and distributing. Each mode has its own virtue attached to it. Wisdom governs choosing, courage governs enduring, temperance governs staying, and justice governs distributing.

Wisdom is knowledge of what is good, bad, or neither, and it shapes every choice you make. Courage is knowledge of what deserves fear and what does not, tested whenever holding steady costs you something. Temperance is knowledge of what to choose and what to avoid, applied to desire. Justice is knowledge of how to distribute what each person is actually due.

The four are never fully separate from each other. Human reason is a fragment of the same reason that governs the whole cosmos. Virtue is simply that reason functioning correctly. This is why Chrysippus argued that holding one virtue genuinely means holding all four. A person cannot be wise without also being just, or brave without also being temperate.

Each virtue below gets its own full article. It covers the virtue’s meaning, its place among the other three, and how to actually practice it. You can start wherever feels most relevant, or follow the order the Stoics themselves used: wisdom, courage, temperance, then justice.
