Rediscovering the later version of Maslow's hierarchy of needs: Self-transcendence and opportunities for theory, research, and unification

The conventional description of Abraham Maslow's (1943, 1954) hierarchy of needs is inaccurate as a description of Maslow's later thought. Maslow (1969a) amended his model, placing self-transcendence as a motivational step beyond self-actualization. Objections to this reinterpretation are considered. Possible reasons for the persistence of the conventional account are described. Recognizing self-transcendence as part of Maslow's hierarchy has important consequences for theory and research: (a) a more comprehensive understanding of worldviews regarding the meaning of life; (b) broader understanding of the motivational roots of altruism, social progress, and wisdom; (c) a deeper understanding of religious violence; (d) integration of the psychology of religion and spirituality into the mainstream of psychology; and (e) a more muiticulturally integrated approach to psychological theory.
