On Cheerfulness

Tradition: Greek atomism / Pre-Socratic ethics
Democritus's c. 420 BCE ethical treatise — euthumia (cheerfulness) as the proper end of human life
On Cheerfulness (Peri Euthumiēs) was Democritus's ethical treatise. The work argued that the proper end of human life is euthumia — "cheerfulness" or "well-being of soul" — understood as the calm-stable condition of the soul achieved through moderate desires, the avoidance of excessive expectations, the proper exercise of practical reason. Major source-text for Hellenistic ethics; Democritus's ethical fragments — preserved in greater number than his physical fragments — are among the most extensive pre-Socratic ethical materials. Lost; the fragments are extensive.
