Hexis (Ancient Greek: ἕξις) is a relatively stable arrangement or disposition, for example a person's health or knowledge or character. It is an Ancient Greek word, important in the philosophy of Aristotle, and because of this it has become a traditional word of philosophy. It stems from a verb related to possession or "having", and Jacob Klein, for example, translates it as "possession". It is more typically translated in modern texts occasionally as "state" (e.g., H. Rackham), but more often as "disposition".
