From personal spiritual insight, Rudolf Steiner renews and broadens the ancient teaching of the four temperaments. He explains how each person’s mixture of temperaments is shaped, usually with one dominating. Steiner provides lively descriptions of the passive, comfort-seeking phlegmatic; the fickle, flitting sanguine; the pained, gloomy melancholic; and the fiery, assertive choleric. He also offers practical suggestions for teachers and parents in addressing the differing manifestations of the temperaments in children, as well as advice intended for adults’ personal development.
