Final answer:
According to Hippocrates, there are four types of personality temperaments based on the body's fluids or 'humours'. These temperaments describe different traits and behaviours.
Step-by-step explanation:
The concept of personality according to Hippocrates is based on four separate temperaments associated with four fluids or 'humours' of the body: choleric temperament (yellow bile), melancholic temperament (black bile), sanguine temperament (red blood), and phlegmatic temperament (white phlegm). These temperaments describe different personality traits and behaviors. For example, a choleric person is passionate and ambitious, while a melancholic person is reserved and anxious.
