Book excerpt: This book of expert essays explores the concept of the whole as it operates within the psychology of Jung, the philosophy of Deleuze, and selected areas of wider twentieth-century Western culture, which provided the context within which these two seminal thinkers worked. Addressing this topic from a variety of perspectives and disciplines and with an eye to contemporary social, political, and environmental crises, the contributors aim to clarify some of the epistemological and ethical issues surrounding attempts, such as those of Jung and Deleuze, to think in terms of the whole, whether the whole in question is a particular bounded system (such as an organism, person, society, or ecosystem) or, most broadly, reality as a whole. Jung, Deleuze, and the Problematic Whole will contribute to enhancing critical self-reflection among the many contemporary theorists and practitioners in whose work thinking in terms of the whole plays a significant role.
