Integral thought (also called the integral paradigm, the integral movement, or the integral approach) is a movement that seeks a comprehensive understanding of humans and the universe by combining scientific and spiritual insights. According to the Integral Transformative Practice website, integral means "dealing with the body, mind, heart, and soul."
Integral thought is seen by proponents as going beyond rationalism and materialism. It attempts to introduce a more universal and holistic perspective or approach. Proponents view rationalism as subordinating, ignoring, and/or denying spirituality. Ken Wilber, one of the most prominent contemporary integral thinkers, begins by acknowledging and validating mystical experience, rather than denying its reality. As these experiences have occurred to humans in all cultures in all eras, integral theorists accept them as valuable and not pathological. Integral thinkers like Sri Aurobindo, and Wilber have argue that both science and mysticism (or spirituality) are necessary for complete understanding of humans and the universe.
Historical development of integral thought
The adjective "integral" was first used in a spiritual context by Sri Aurobindo from 1914 onward to describe his own yoga, which he referred to as Purna (Skt: "Full") Yoga. It appeared in The Synthesis of Yoga, a book that first published in serial form in the journal Arya and was revised several times since .
The word was totally independently suggested by Jean Gebser in 1939 to describe his own intuition regarding the next state of human consciousness. Gebser only afterwards discovered the similarity with Sri Aurobindo 
Haridas Chaudhuri, a student of Sri Aurobindo and philosophy in his own right, developed his own perspective and philosophy. established the California Institute of Integral Studies (originally the "California Institute of Asian Studies"), in 1968 in San Francisco, (it became an independent organisation in 1974), and presented his own form of Integral psychology in the early 1970s 
In late 1990s and 2000 Ken Wilber, who was influenced by both Aurobindo and Gebser, among many others, adopted the term "Integral" to refer to the latest revision ("Wilber-IV") of his own philosophy, which he called Integral theory. He also established the Integral Institute as a think-tank for further development of these ideas. In his book Integral Psychology Wilber lists a number of pioneers of the integral approach, post hoc. These include Goethe, Schelling, Hegel, Gustav Fechner, William James, Rudolf Steiner, Alfred North Whitehead, James Mark Baldwin, Jurgen Habermas, Sri Aurobindo, and Abraham Maslow 
Sri Aurobindo and The Mother
Sri Aurobindo (1872-1950) was a visionary yogi rather than a systematizer, and although he referred to "integral" only in the context of spiritual transformation, his writings influenced others who used the term "integral" in more philosophical or psychological contexts. The word "integral" was originally used by Sri Aurobindo and the Mother to describe the yoga they taught. Their integral yoga involves an integral divine transformation of the entire being, rather than the liberation of only a single faculty such as the intellect or the emotions or the body. Important teachings include: Evolution, Involution, the Integral psychology, the psychic being, Integral yoga, the Triple transformation, and the Supramental principle. Major works include: The Life Divine, The Synthesis of Yoga, and Savitri. According to Aurobindo,
But the Divine is in his essence infinite and his manifestation too is multitudinously infinite. If that is so, it is not likely that our true integral perfection in being and in nature can come by one kind of realisation alone; it must combine many different strands of divine experience. It cannot be reached by the exclusive pursuit of a single line of identity till that is raised to its absolute; it must harmonise many aspects of the Infinite. An integral consciousness with a multiform dynamic experience is essential for the complete transformation of our nature. — Sri Aurobindo, The Synthesis of Yoga, p.114
The Mother (1878-1973) was Sri Aurobindo's co-worker. She continued Sri Aurobindo's work of Integral Yoga and spiritual transformation after his passing, and founded Auroville, an international community dedicated to human unity, and based on their teachings. A record of some of her experiences have been collected by her disciple Satprem in a thirteen volume work called Mother's Agenda.
Followers of The Mother and Sri Aurobindo
The following authors/ organizations (listed in chronological order?) trace their intellectual heritage back to, or have in some measure been influenced by, The Mother and Sri Aurobindo.
- Sisir Kumar Maitra (1887-?) was an academic philosopher who wrote widely on Sri Aurobindo and Western philosophy. Wrote an essay, "Sri Aurobindo and Spengler: Comparison between the Integral and the Pluralistic philosophy of History" in the 1958 symposium compendium, 'The Integral Philosophy of Sri Aurobindo.'
- Nolini Kanta Gupta (1889 - 1983) was one of Sri Aurobindo's senior disciples, and wrote extensively on philosophy, mysticism, and spiritual evolution in the light of Sri Aurobindo and The Mother's teachings.
- Ram Shankar Misra (dates?) was a scholar of Indian religious and philosophical thought and author of The Integral Advaitism of Sri Aurobindo (publ. 1957), a philosophical commentary on Sri Aurobindo's work.
- Haridas Chaudhuri (1913-1975), a Bengali philosopher, was a correspondent with Sri Aurobindo and founded the California Institute of Integral Studies. In the Chapter IX captioned, "The Vedanta as Integral Non-dualism" of his 1951 book, Sri Aurobindo: The Prophet of Life Divine he described Sri Aurobindo's philosophy as purnadvaita-vada. Author of the book, 'Philosophy of Integralism,' he later developed his own theory of Integral psychology. Along with Frederic Spiegelberg, he wrote the title paper and edited the 1958 symposium compendium, The Integral Philosophy of Sri Aurobindo.
- Dennis Hargiss coined the term "Integral phenomenology" to refer to the use of integral psychology for the study of mysticism and the sacred.
Organisations and institutes
- The New Life Education Trust, Matrubhaban, Sri Aurobindo Marg, Cuttack - oversees a chain of 429 Sri Aurobindo Integral Education Centres in Orissa, India. Most of these secondary schools are in rural areas set up with local initiative. Babaji Sri Ramakrishna Das and Prapatti, Kangali Charan Pati were the dominant inspiration.
- Sri Aurobindo International Institute for Integral Health and Research, Puducherry - Dr. Alok Pandey is one of the founders of SAIIIHR. Dr.Soumitra Basu is the author of the book on 'Integral Health' and Editor of NAMAH. He is also one of the founders of SAIIIHR.
Jean Gebser (1905-1973), was a Swiss phenomenologist, and author of The Ever-Present Origin. He conceived of history as a series of mutations in consciousness. Gebser saw in the momentous events of the 1930s and '40s a new mutation in consciousness which he identified as the transition to the integral stage.
American writer and Buddhist Ken Wilber (b. 1949) is one of the most popular integral writers in the world today. Wilber popularized Integral thought or integral thinking in the current sense, to develop an all-encompassing, evolutionary theory that incorporates and honours all perspectives, while at the same time presenting a larger picture. Wilber, borrowing centrally from the writings of Adi Da, also built upon the ideas of previous integral thinkers like Sri Aurobindo and Jean Gebser in developing his own highly complex integral theory.
Wilber's books include: Sex Ecology Spirituality, Integral Psychology, and Boomeritis. His major ideas include: AQAL, integral ecology, integral politics, and vision-logic. Founder of the Integral Institute, Integral Naked, and Integral University. According to Wilber,
The word integral means comprehensive, inclusive, nonmarginalizing, embracing. Integral approaches to any field attempt to be exactly that—to include as many perspectives, styles, and methodologies as possible within a coherent view of the topic. In a certain sense, integral approaches are "meta-paradigms," or ways to draw together an already existing number of separate paradigms into an interrelated network of approaches that are mutually enriching." —Ken Wilber, "Foreword", in Frank Visser, Ken Wilber: Thought As Passion
Elsewhere, he says:
This means that the chief activity of integral cognition is not looking at all of the available theories—whether premodern, modern, or postmodern—and then asking, "Which one of those is the most accurate or acceptable?," but rather consists in asking, "How can all of those be right?" The fact is, all of the various theories, practices, and established paradigms—in the sciences, arts, and humanities—are already being practiced: they are already arising in a Kosmos that clearly allows them to arise, and the question is not, which of those is the correct one, but what is the structure of the Kosmos such that it allows all of those to arise in the first place? What is the architecture of a universe that includes so many wonderful rooms? — Ken Wilber, "The Ways We Are in This Together: Intersubjectivity and Interobjectivity in the Holonic Kosmos" Excerpt C of draft of forthcoming book, Kosmic Karma and Creativity
Wilberian Integral thought
The following authors (listed in chronological order) are or have in the past been influenced by Wilber, but not by Aurobindo (except secondarily through Wilber's presentation of him).
- Andrew Cohen (b. 1955) is an American guru and author of "evolutionary spirituality." He has been influenced by a number of evolutionary thinkers, including Sri Aurobindo, and is a friend of and collaborater with Ken Wilber. He is founder and editor in chief of What Is Enlightenment?, a quarterly magazine that features essays by and interviews with many integral thinkers.
- Allan Combs is the author of The Radiance of Being: Understanding the Grand Integral Vision, Living the Integral Life. He has worked with Ken Wilber recently to create a theory which they call the "Wilber-Combs Lattice".
Integral thought - Sri Aurobindo and Ken Wilber
The following authors (listed in chronological order) have been influenced by or created a synthesis of the teachings of both Aurobindo and Wilber (and also other thinkers as well):
- See main article Integral art
Integral art can be defined as art that reaches across multiple quadrants and levels, or simply as art that was created by someone who thinks or acts in an integral way. These artists may have been influenced by integral thinkers, or developed integral art independently.
- Johannes Wallmann (b. 1952) is a composer and integral musician
- Alex Grey (b. 1953) is a psychedelic visual artist whose works have been admired by Wilber and others.
- Stuart Davis (b. 1971) is a songwriter/musician, calligrapher with his own language, and cyberartist.
Other integral thinkers
The following thinkers and teachers use the term "integral", but are not necessarily associated with or followers of either Sri Aurobindo, Jean Gebser, or Ken Wilber.
- Ervin László (b. 1932) is a philosopher of science, systems theorist, and integral theorist who posits a field of information as the substance of the cosmos.
- William Irwin Thompson (b. 1938) is a cultural historian influenced by Aurobindo and Jean Gebser. In his 1996 book Coming Into Being, he re-envisioned global cultural history as the continuing evolution of consciousness. He is the founder of the Lindisfarne Association. He has criticized Wilber's integral theory as being excessively objectifying and masculinist.
- Yasuhiko Kimura (b. 1954) is integral philosopher, writer, and lecturer.
- Roland Benedikter (b. 1965) is a Member of the Institute for the History of Ideas and Research on Democracy, Innsbruck, Austria, and has written books and essays on a number of subjects including postmodernist spirituality and integral thought.
Many writers and artists who did not use the word "integral" to refer to their theories nonetheless are considered by the integral community as theorists that act, think or theorize in an integral way but this label is only speculation on the integral community's part. These include contemporary thinkers like Jurgen Habermas and Rupert Sheldrake, and historical figures like Ralph Waldo Emerson and Gandhi.
According to Richard Tarnas:
The remarkable modern capacity for differentiation and discernment that has been so painstakingly forged must be preserved, but our challenge now is to develop and subsume that discipline in a more encompassing, more magnanimous intellectual and spiritual engagement with the mystery of the universe. Such an engagement can happen only if we open ourselves to a range of epistemologies that together provide a more multidimensionally perceptive scope of knowledge. To encounter the depths and rich complexity of the cosmos, we require ways of knowing that fully integrate the imagination, the aesthetic sensibility, moral and spiritual intuition, revelatory experience, symbolic perception, somatic and sensuous modes of understanding, empathic knowing. Above all, we must awaken to and overcome the great hidden anthropocentric projection that has virtually defined the modern mind: the pervasive projection of soullessness onto the cosmos by the modern self’s own will to power. Richard Tarnas, Cosmos and Psyche, pg.41
The following writers contributed essential ideas to integral thought:
- John Heron (b. 1928) is a pioneer in the creation of a participatory research method (co-operative inquiry) in the social sciences, which has been applied by practitioners in many fields of professional and personal development. He is committed to co-operative inquiry as a basic form of relational and participative spiritual practice.
- David Spangler (b. 1945) is an American spiritual philosopher and "practical mystic". With William Irwin Thompson he helped found of the Lindisfarne Association. He is author of Incarnational spirituality; a holistic, pragmatic approach to spirituality which rejects the otherworldly focus of conventional contemplative mysticism in favour of spiritual action by the physical, everyday self, recognition of the sacredness of the world around us, and balance of the inner and outer being.
- Georg Feuerstein (b. 1947) is the author of Wholeness or Transcendence: Ancient Lessons for the Emerging Global Civilization, Structures of Consciousness: The Genius of Jean Gebser, An Introduction and Critique, co-author of In Search of the Cradle of Civilization, and founder of the Yoga Research and Education Center and Traditional Yoga Studies.
- Richard Tarnas (b. 1950) is the author of The Passion of the Western Mind and Cosmos and Psyche. He is also a founding director of the graduate program in Philosophy, Cosmology, and Consciousness at the California Institute of Integral Studies. Tarnas is the originator of Participatory Epistemology.
- Michel Bauwens (b. 1958) views peer-to-peer technology as an integral phenomenon. He is a contributor to the journal Integral Review. He is a proponent of the participatory spirituality of John Heron and Jorge Ferrer, and is critical of cultic and authoritarian aspects of Wilber and his organisation.
- Jorge Ferrer is the author of Revisioning Transpersonal Theory: A Participatory Vision of Human Spirituality and a core faculty member in the East-West Psychology Program at the California Institute of Integral Studies. His book is an attempt to go beyond both the influence of Ken Wilber in transpersonal psychology and the epistemological implications of postmodernism by means of Richard Tarnas' participatory epistemology.
