The Four Temperaments (Lectures Section)

Between individual characteristics and those of the human race in general lie the four main groups of human temperaments: phlegmatic, sanguine, melancholic, and choleric. Steiner describes here how each person’s combination of temperaments is shaped out of a particular kind of union between hereditary factors and the inner spiritual nature.
