Volume Seven of The Collected Works of Ken Wilber includes: - A Brief History of Everything (1996) "Combining spiritual sensitivity with enormous intellectual understanding and a style of elegance and clarity, [this book] is a clarion call for seeing the world as a whole."-- San Francisco Chronicle . - The Eye of Spirit: An Integral Vision for a World Gone Slightly Mad (1997) uses the spectrum model to create an integral approach to psychology, spirituality, anthropology, cultural studies, and art. - "An Integral Theory of Consciousness," an essay previously unpublished in book form, presents one of the first theories to integrate first-, second-, and third-person accounts of consciousness.
