"Fascinating. I never believed that scientific researchers could probe so deeply into the brains, and the minds, of dreamers, psychotics, and individuals under the influence of drugs."
-- Howard Gardner, Professor of Education, Harvard University

""The reality of the mind disclosed by neurobiology, which Allan Hobson expertly and clearly explains, is stranger, more marvelous, and philosophically more potent than anything previously conceived, even in the farthest reaches of psychoanalysis."
-- Edward O. Wilson, Harvard University, author of Sociobiology
