Life and its meaning is a mystery almost impossible to solve, but what can the leading theories teach us about the search for purpose? For most of us, the major questions of life continue to perplex: Who am I? Why am I here? How should I live? In the late nineteenth century, a class of thinkers emerged who made solving these problems central to their work. They understood that human questions demand human answers and that without understanding what it means to be human, there are no answers. Through the biographies and theories of luminaries ranging from Sigmund Freud to Erich Fromm, Frank Tallis show us how to think about companionship and parenting, identity and aging, and much more. Accessible yet erudite, The Act of Living is essential reading for anyone seeking answers to life's biggest questions.
