Аннотация:Abstract This introductory chapter clarifies how contemporary organizational scholars view emergence and novelty. As the use of these terms has grown, their meanings have become increasingly diffuse. In response, the chapter explicates three lenses that tease out core distinctions between different philosophical and theoretical approaches to studying emergence. Each of the three lenses-spatial emergence, relational emergence, and temporal emergence-is based on a unique pairing of underlying assumptions about the exogenized or endogenized nature of both space and time. Each also has particular implications for practitioners seeking insights into emergence, and for researchers conducting studies on emergence. The chapter also introduce the other chapters in this volume, which offer a variety of philosophical, theoretical, and empirical perspectives on the theme of novelty emergence. Chapters in Part I engage directly with this theme. The chapters in Part II address developments more generally in the domain of process organization studies.
