Reprint of 1943 Edition.This is the article in which Maslow first presented his hierarchy of needs. It was first printed in his 1943 paper “A Theory of Human Motivation”. Maslow subsequently extended the idea to include his observations of humans’ innate curiosity. His theories parallel many other theories of human developmental psychology, some of which focus on describing the stages of growth in humans. Maslow described various needs and used the terms “Physiological, Safety, Belongingness and Love, Esteem, Self-Actualization and Self-Transcendence” needs to describe the pattern that human motivations generally move through. Maslow studied what he called exemplary people such as Albert Einstein, Jane Addams, Eleanor Roosevelt, and Frederick Douglass rather than mentally ill or neurotic people.

The present paper is an attempt to formulate a positive theory of motivation which will satisfy these theoretical demands and at the same time conform to the known facts, clinical and observational as well as experimental. It derives most directly, however, from clinical experience. This theory is, I think, in the functionalist tradition of James and Dewey, and is fused with the holism of Wertheimer, Goldstein, and Gestalt Psychology, and with the dynamicism of Freud and Adler. This fusion or synthesis may arbitrarily be called a ‘general-dynamic’ theory. It is far easier to perceive and to criticize the aspects in motivation theory than to remedy them. Mostly this is because of the very serious lack of sound data in this area. I conceive this lack of sound facts to be due primarily to the absence of a valid theory of motivation. The present theory then must be considered to be a suggested program or framework for future research and must stand or fall, not so much on facts available or evidence presented, as upon researches to be done, researches suggested perhaps, by the questions raised in this paper.
