The uniqueness of an individual or 'temperament' is an important pillar of Tibb.
Temperament describes a person's physical characteristics (the constitution) plus his or her psychological, emotional, and spiritual attributes. It assesses personality strengths and weaknesses, and includes the predisposition (risk factors) for particular disorders.

Temperament is identified by evaluating a person's physical appearance, behavioral tendencies as well as personality traits:

• Physical appearance: takes into account the frame of the person, texture of skin and complexion. A true reflection of the physical appearance is the appearance in the early twenties as changes may take place over age.

• Behavioural tendencies: includes preferences to weather, food and drink.
One must be careful not to confuse habits with tendencies. A person may be inclined to acquire certain habits because of circumstances. You may misinterpret these as preferences. For example, it is common to be served drinks with ice at most occasions, making one believe that you prefer cold drinks.

• Personality traits: considers whether a person is calm or prone to anger, talkative, etc. When evaluating personality traits, consider how other people view you, especially those who know you well such as family and friends. When evaluating personality traits, take cognisance of the fact that lifestyle may alter your inherent personality traits. It is thus advised that you reflect on these traits objectively.
