Ryan and Todd trace the history of how thinkers have dealt with the problem of love--the varying definitions of love, the view of love's role in society, and love's philosophical importance. They begin with Plato's Symposium, touch on the New Testament, explore the role of love in Hegel's thought, discuss Badiou's love event, and conclude with the psychoanalytic conception of love, as developed by Jacques Lacan and Mari Ruti.
