 Aristotle describes ethical virtue as a “hexis” (“state” “condition” “disposition”)—a tendency or disposition, induced by our habits, to have appropriate feelings (1105b25–6). Defective states of character are hexeis (plural of hexis) as well, but they are tendencies to have inappropriate feelings. The significance of Aristotle’s characterization of these states as hexeis is his decisive rejection of the thesis, found throughout Plato’s early dialogues, that virtue is nothing but a kind of knowledge and vice nothing but a lack of knowledge. Although Aristotle frequently draws analogies between the crafts and the virtues (and similarly between physical health and eudaimonia), he insists that the virtues differ from the crafts and all branches of knowledge in that the former involve appropriate emotional responses and are not purely intellectual conditions.
