What, we might ask, is this thing called “temperament,” and what relation does it have to character and personality? There are two sides to personality, one of which is temperament and the other character. Temperament is a configuration of inclinations, while character is a configuration of habits. Character is disposition, temperament pre-disposition. Thus, for example, foxes are predisposed — born — to raid hen houses, beavers to dam up streams, dolphins to affiliate in close-knit schools, and owls to hunt alone in the dark. Each type of creature, unless arrested in its maturation by an unfavorable environment, develops the habit appropriate to its temperament: stealing chickens, building dams, nurturing companions, or hunting at night.
