 Pneuma comes in gradations and endows the bodies which it pervades with different qualities as a result. The pneuma which sustains an inanimate object is (LS) a ‘tenor’ (hexis, lit. a holding). Pneuma in plants is, in addition, (LS) physique (phusis, lit. ‘nature’). In animals, pneuma is soul (psychê) and in rational animals pneuma is, besides, the commanding faculty (hêgemonikon) (Diog. Laert. 47O, Philo 47P) – that is responsible for thinking, planning, deciding. The Stoics assign to ‘physique’ or ‘nature’ all the purely physiological life functions of a human animal (such as digestion, breathing, growth etc.) – self-movement from place to place is due to soul.
