Nearly forty years ago I discovered a profoundly significant idea. Quite simply: the key to wisdom. For over two and a half thousand years, philosophy (which means “love of wisdom”) has sought in vain to discover how humanity might learn to become wise – how we might learn to create an enlightened world. For the ancient Greek philosophers, Socrates, Plato and the rest, discovering how to become wise was the fundamental task for philosophy. In the modern period, this central, ancient quest has been laid somewhat to rest, not because it is no longer thought important, but rather because the quest is seen as unattainable. The record of savagery and horror of the last century is so extreme and terrible that the search for wisdom, more important than ever, has come to seem hopeless, a quixotic fantasy. Nevertheless, it is this ancient, fundamental problem, lying at the heart of philosophy, at the heart, indeed, of all of thought, morality, politics and life, that I have solved. Or so I believe.
