What kind of an emotion is regret? What difference does it make whether, how, and why we experience it, and how does this experience shape our current and future thoughts, decisions, goals? Under what conditions is regret appropriate? Is it always one kind of experience, or does it vary, based on who is doing the regretting, and why? How is regret different from other backward-looking emotions? In The Moral Psychology of Regret, scholars from several disciplines—including philosophy, gender studies, disability studies, law, and neuroscience—come together to address these and other questions related to this ubiquitous emotion that so many of us seem to dread. And while regret has been somewhat under-theorized as a subject worthy of serious and careful attention, this volume is offered with the intent of expanding the discourse on regret as an emotion of great moral significance that underwrites how we understand ourselves and each other.
