Development of personality as a discipline in psychology

Abstract

The history of personality dates as far as in the era of Ancient Greek medicine and philosophy when philosophers have been searching ways to define what exactly make us who we are. When the ‘Father of Medicine’, Hippocrates (c.460-377 BC) worked on the notable ‘Four Temperaments or Four Humours’, the Temperament theory which was rooted from the ancient humors theory was developed into a medical theory. These bodily fluids (blood, phlegm, yellow bile and black bile) were linked to different organs and illnesses as represented in the “Four Temperaments and Four Humours” of personality.
