ARISTO or ARISTON, of Chios (c. 250 B.c. ), a Stoic phi losopher and pupil of Zeno, though he approximated more closely to the Cynic school. He considered only ethics worthy of study, and in that only general and theoretical questions. He rejected Zeno's doctrine of desirable things, intermediate between virtue and vice. There is only one virtue—an intelligent, healthy state of mind (hygeia). Aristo is frequently confounded with Ariston of Iulis, who became scholarch of the Peripatetics about 23o B.c.
