This book, split across two volumes, is a follow-up and companion to Metatheory for the Twenty-First Century (Routledge, 2016). All three of these volumes are the dialogical outcome of a multi-year symposia series wherein critical realists and integral theorists deeply engaged each other and their distinct but complementary approaches to integrative metatheory. Whereas Metatheory for the Twenty-First Century is primarily theoretical in its focus, Big Picture Perspectives for Planetary Flourishing: Metatheory for the Anthropocene aims to more concretely and practically address the complex planetary crises of a new era that many scholars now refer to as ‘the Anthropocene.’ In this first of two new volumes, participants of the symposia series articulate a variety of ‘big picture perspectives’ and transformative interventions in the domains of society and economics, social psychology, and education. Together, these chapters demonstrate how integrative metatheory and its application can make powerful contributions to planetary flourishing in the Anthropocene. With one of the defining characteristics of the Anthropocene being the sheer complexity and multi-valent nature of our interconnected global challenges, these volumes crucially present new forms of scholarship that can adequately weave together insights from multiple disciplines into new forms of metapraxis. As such, this book will be of interest to students, scholars, and practitioners in the areas of philosophy, social theory, critical realism, integral studies, metamodernism, and current affairs generally.
