This collection of essays, offered in honor of the distinguished career of prominent political philosophy professor Clifford Orwin, provides a wide context in which to consider the rise of "humanity" as one of the chief modern virtues. A relative of—and also a replacement for—formerly more prominent other-regarding virtues like justice and generosity, humanity and later compassion become the true north of the modern moral compass. Contributors to this volume consider various aspects of this virtue, by comparison with what came before and with attention to its development from early to late modernity, and up to the present.
