Brilliantly, the author explores the very different philosophers and writers, both skeptics and believers, who dared to think differently: from Aristotle's perfect friendship and Ovid's celebration of sex and "the chase," to Rousseau's personal authenticity, Nietzsche's affirmation, Freud's concepts of loss and mourning, and boredom in Proust. Against our belief that love is an all-powerful solution to finding meaning, security, and happiness in life, the author reveals with great clarity what love actually is: the intense desire for someone whom we believe can ground and affirm our very existence. The feeling that "makes the world go round" turns out to be a harbinger of home--and in that sense, of the sacred.
