Four temperaments is a proto-psychological theory that suggests that there are four fundamental personality types, sanguine (enthusiastic, active, and social), choleric (short-tempered, fast, or irritable), melancholic (analytical, wise, and quiet), and phlegmatic (relaxed and peaceful). Most formulations include the possibility of mixtures of the types where individual share two or more temperaments.

The Greek physician Hippocrates (c. 460 – c. 370 BC) incorporated the four temperaments into his medical theories as part of the ancient medical concept of humorism, that four bodily fluids affect human personality traits and behaviors. Later discoveries in biochemistry have led modern medical science to reject the theory of the four temperaments, although some personality type systems of varying scientific acceptance continue to use four or more categories of a similar nature
