Maslow’s motivational hierarchy
the hierarchy of human motives, or needs, as described by Abraham Maslow, which he developed in part as a reaction against the determinism of the theories of Sigmund Freud and B. F. Skinner. Physiological needs (air, water, food, sleep, sex, etc.) are at the base; followed by safety and security (the safety needs); then love, affection, and gregariousness (the love needs); then prestige, competence, and power (the esteem needs); and, at the highest level, aesthetic needs, the need for knowing, and self-actualization (the metaneeds).
