Religions, Values, and Peak-Experiences

Maslow's core argument is that the private illumination, revelation, or ecstasy reported by prophets and mystics across traditions is psychologically identical to the peak experience—a natural, species-wide capacity available to healthy, non-religious people as well. He rejects two dichotomies: the separation of science from values, and the confinement of the sacred to institutional religion. Organized churches, he argues, have monopolized the language of value and the transcendent, often deadening the very experiences they claim to mediate through concretized symbols and bureaucratic control . The book is an attempt to reclaim values and spiritual experience for a humanistic science that studies them empirically rather than metaphysically.

The distinction is one of Maslow's most idiosyncratic contributions in this volume. "Peakers" are individuals who have access to transcendent, peak experiences and can use them for personal growth, therapy, and fulfillment. "Non-peakers" are those who, whether by temperament or by absorption in the materialistic, mechanical, or purely rational, never undergo such experiences and are therefore denied their psychological benefits . Maslow uses this typology to explain the perennial conflict within religious traditions between mystics and administrators: mystics are peakers whose authority derives from direct experience, while clerics are often non-peakers who rely on ritual, doctrine, and organizational control. The distinction is descriptive, not evaluative in Maslow's explicit framing, though his sympathy for the peakers is evident.

Maslow explicitly acknowledged James as a major influence, and the book's editorial introduction names both James's Varieties and John Dewey's A Common Faith as shaping Maslow's views . The relationship is one of revision and naturalization. James catalogued the astonishing diversity of religious experience and defended its reality against reductive medical materialism. Maslow takes the next step: he argues that the essence of the most intense religious experiences—conversion, mystical illumination, revelation—is not distinctively religious at all but is a peak experience, a natural psychological event. Where James preserved a tension between the religious and the scientific, Maslow dissolves it by making the core-religious experience an object of scientific study, accessible to atheists and theists alike.

B-values (Being-values) are the intrinsic qualities Maslow found to characterize perception during peak experiences: truth, goodness, beauty, unity, aliveness, uniqueness, and similar descriptors. They are not moral rules imposed from outside but descriptions of how reality appears to a person in the B-mode of cognition. Maslow argues that because these values are empirically derived from the reports of peak-experiencers, they provide a naturalistic foundation for ethics that does not require theological grounding. In the book's appendixes he develops this at length, treating B-values as a "perfectly naturalistic variety" of certainty and universality . The claim is bold: science can study values because values are facts about human experience at its fullest.

The core-religious experience is the private, lonely, personal illumination or ecstasy of the prophet or seer—the experiential kernel beneath the doctrinal and institutional husk of any tradition . Maslow insists that this kernel is the same across religions, which is why he hypothesizes that all religions are essentially identical at their experiential core. It differs sharply from ordinary religious belief, which is propositional, culturally transmitted, and often held without any corresponding experience. A person can be devoutly religious in the belief sense and never have a peak experience; conversely, a convinced atheist can have one. Maslow's point is that the experiential core is what matters psychologically, and it is available outside any faith tradition.

The book has been less influential than Maslow's hierarchy work, and its central claims have drawn sustained critique. The assertion that peak experiences are neurologically or phenomenologically identical across religious traditions is difficult to verify and has been challenged by scholars who emphasize the culturally shaped content of mystical experience. The sharp peaker/non-peaker dichotomy has been criticized as empirically thin, lacking a validated measure or clear diagnostic criteria. The proposal that B-values can ground a universal ethics has not been widely adopted in moral philosophy or psychology. Nevertheless, the book remains a significant document in the history of humanistic and transpersonal psychology, and its naturalistic approach to religious experience anticipates later empirical studies of awe, self-transcendence, and psychedelic experience.
