These definitions imply that behavior and personality can be understood only in the context of the whole person. This does not necessarily indicate that parts of the personality cannot be studied separately. It implies only that those studies cannot lead to complete understanding. A useful distinction can be made between subjective and objective definitions of personality. We see then that personality has two meanings.
Personality is the private world of one's inner experiences.
It is also a scientific assessment of a person that makes possible predictions of future behavior. Some people believe that something significant about personal- ity is revealed in such classifications. One difficulty with these type approaches to personality is that the extent or degree of each characteristic is not measured. An individual either does or does not belong to a type, according to these classification schemes. But personality is not that simple.
