SIX YEARS AGO, in 1989, I set out across the country on my own search for wisdom. In the course of my travels, I interviewed and worked with more than two hundred psychologists, philosophers, physicians, scientists, and mystics who claimed to have the answers I was after. By the time I wrote What Really Matters: Searching for Wisdom in America, it was clear to me that Ken Wilber was in a category by himself. He is, I believe, far and away the most cogent and penetrating voice in the recent emergence of a uniquely American wisdom.
