需求
When basic needs are insecure, all idealism withers.
The deepest need of man is the need to overcome his separateness, to leave the prison of his aloneness.
What a man can be, he must be. This need we call self-actualization.
The goal of behavior is always the reduction of some drive or need.
Psychology must show how mind serves the needs of the organism.
The mind evolves to meet the demands of existence.
The function of mental processes is to mediate between the needs of the organism and the demands of the environment.
