For over 2000 years, a Greek philosopher and physicist was the first to realize that people are not the same.
Hippocrates first noted that despite the differences in appearance, people also have unique personalities that distinguish them decisively.
Around 400 BC he identified four organic liquids - blood, pale bile, phlegm, and black bile - which yielded different character traits in people.
Several centuries later, around 149 BC a Roman physiologist, Galen, proposed a theory of psychology based on the theory of Hippocrates. According to this there are four types of human personality - the blood, the choleric, the melancholic, and phlegmatic - depending on the specific quantity of organic liquid flow in the body of every human being.
Of course, later scientists discovered that these four organic liquids are not responsible for the personality characteristics of people, but are a different biological entity: our genes.
But although every human being is unique, there are traits of personality can be grouped into categories that help us better understand who we are and why others are not the same as us.
These four types are rendered in Greek terms:
The popular - blood,
The mighty - choleric,
The perfect -melancholic,
and The peaceful - phlegmatic.
