Dr. Gordon Livingston's books have resonated with readers as universally and deeply as earlier books by M. Scott Peck, Rollo May, and Erich Fromm. Now, Gordon Livingston—a physician of the human heart, a philosopher of human psychology—offers an urgently needed meditation on who best (and who best not) to love—and how best to love. Dr. Livingston's primary focus in this new book is on helping us to recognize in ourselves and in others constellations of character traits and what those traits imply both with regard to compatibility and future conduct. As in his previous books, here are Dr. Livingston's trademark gifts—an unerring sense of what is important, and what Elizabeth Edwards has characterized as “his unapologetic directness and his embracing compassion?—again deployed to provide readers everywhere with a much-needed alternative to the trial-and-error learning that makes wisdom such an expensive commodity.
