Revered as the "Einstein of consciousness," Ken has written over twenty books exploring different facets of human development and cultural evolution. His first book, The Spectrum of Consciousness, written when he was only 23, became a seminal text in the emerging field of transpersonal psychology. Among his diverse corpus of writings are a novel, Boomeritis, which provided a groundbreaking critique of postmodernity, and The Simple Feeling of Being, a corpus of mystical, spiritual writings of transcendent and lyrical beauty.
Wilber has also played an active role in supporting and promoting integral thinking. He is a leading voice in support of World Spirituality based on Integral principles and has been one of the founding members of the Wisdom Council of the Center for Integral Wisdom.
