All That Matters argues that the modern view on love has been distorted by a fixation on romantic love that has depleted our resources for living through the darker sides of love, whereas in fact there are several ways in which humans give and experience love over the course of their lives and it is best to have access to them all. Vernon draws on science, psychology, philosophy and literature, to examine eight different kinds of love, each associated with a phase of human development. From infant narcissism and the emergence of eros, through puberty and the rush of romantic love, to the end of life and the love of God, this is a beguiling tour of the most mysterious force of all. This accessible and readable book will appeal to both students and general readers, giving a fascinating introduction to the psychology and philosophy of love - and what matters most about it.
