Damippus (or Criton) the Pythagorean wrote On Practical Wisdom and Good Fortune. Stobaeus 3.3.63–64 preserves a long Doric treatise: phronasis is the speakable and rational, ordered and bounded; eutychia is the unspeakable and irrational, unordered and unbounded. The first steers, the second is steered; together they make a harmonia. That joining in the whole is cosmos; in a human being, of the irrational psychē to the rational, it is aretē; in a city, of ruled to rulers, it is kratos and homonoia. A second extract: life needs both tension and release, gloom and ease, fortune and mishap, all ordered toward phronasis, leader and mother of the other aretai.
The treatise is printed in the Åbo collection of the Pythagorean texts of the Hellenistic period (1965), pp. 68–69. The attribution is dated to the third century BCE.
The Greek is that ethics of wisdom and luck, not a philosopher with nothing to say.
