The contributors to this book marshal a wide array of postpositivist approaches to knowledge to reconstruct the analytic potential of comparison for a new generation of social scientists. In addition to providing fresh answers to classic questions about case selection and causal inference, authors ponder the role comparison plays in a world where social phenomena are demonstrably time-, space-, and concept-dependent; where causation is typically conjunctural; where social structures and groups emerge and die; and where important objects of inquiry can be understood only in terms of relationships, emergent properties, or contingent and irregular effects.
