Human relationships aren't lawless. When two people share a bond, certain behaviors can be expected. What behavorial norms define friendship, such that certain acts are deemed reprehensible? How do we make friends? Can friendship survive change? Is adultery a betrayal of a romantic relationship, or can we love more than one person at a time? Is it an individual we love, or a collection of traits? Philosopher Monique Canto-Sperber attempts to answer these questions, demystifying human connections. This book takes up themes dear to Stendhal's On Love and Roland Barthes's A Lover's Discourse.
