MANY have helped me in my work, and I am unable to thank them all: this book was several years in the writing, and my debts stretch back beyond,my memory. Rollo May and Dagfinn Follesdal were exceptionally important teachers and guides. Many colleagues read and criticized all or parts of the manuscript: Jerome Frank, Julius Heuscher, Kent Bach, David Spiegel, Alex Comfort, James Bugental, Marguerite Lederberg, Michael Bratman, Mitchell Hall, Alberta Siegel, Alvin Rosenfeld, Herbert Leiderman, Michael Norden, and numerous Stanford psychiatric residents. To all, my gratitude.
