Maslow's Hierarchy of Needs

Maslow's hierarchy of needs is a motivational theory proposing that human needs are arranged in a pyramid of priority. Lower-level needs must be sufficiently satisfied before higher-level needs become motivating forces. The hierarchy, from bottom to top, consists of: physiological needs, safety needs, love and belonging, esteem, and self-actualization.

Abraham Maslow introduced the theory in his 1943 paper "A Theory of Human Motivation." He was reacting against the dominant psychological frameworks of his time — Freud's focus on pathology and Skinner's mechanistic behaviorism — arguing that psychology should also study what makes people thrive, not just what makes them sick. Maslow proposed that the healthiest, most fulfilled individuals — "self-actualizers" — shared characteristics like creativity, spontaneity, acceptance of self and others, and profound "peak experiences" of awe and meaning.

The hierarchy is often depicted as a rigid pyramid, but Maslow himself described it as more flexible. People can be motivated by multiple levels simultaneously, and the order can vary by individual and culture. A starving artist creates despite unmet physiological needs. A soldier sacrifices safety for belonging and honor. Later in life, Maslow added a sixth level above self-actualization: self-transcendence — the need to connect to something beyond the self through spirituality, service, or communion with nature. This addition is often overlooked but represents Maslow's mature vision of human potential.
