Book VII · 48
This is a fine saying of Plato: That he who is discoursing about men should look also at earthly things as if he viewed them from some higher place; should look at them in their assemblies, armies, agricultural labors, marriages, treaties, births, deaths, noise of the courts of justice, desert places, various nations of barbarians, feasts, lamentations, markets, a mixture of all things and an orderly combination of contraries.
Marcus Aurelius, Meditations VII.48. Translated by George Long (1862). The Stoic Library.
