The Four Temperaments is a very old classification of fundamental personality types:
- sanguine - optimistic leader-like
- choleric - bad-tempered or irritable
- melancholic - analytical and quiet and
- phlegmatic - relaxed and peaceful
The Greek physician Hippocrates (c. 460 – c. 370 BC) incorporated the four temperaments into his medicine and the personality type was taken into account when devising healing and medicines well up to the 20th century. It linked in to the concept of the Four humours.
It is only recently that we have ignored the type of person completely when dishing out pharmaceuticals.
