The Palgrave Encyclopedia of the Possible represents a comprehensive resource for researchers and practitioners interested in an emerging multidisciplinary area within psychology and the social sciences: the study of how we engage with and cultivate the possible within self, society and culture. Far from being opposed either to the actual or the real, the possible engages with concrete facts and experiences, with the result of transforming them. This encyclopedia examines the notion of the possible and the concepts and themes associated with it from standpoints within psychology, philosophy, sociology, neuroscience and logic, as well as multidisciplinary fields of research including anticipation studies, future studies, complexity theory and creativity research. Presenting multiple perspectives on the possible, the authors consider the distinct social, cultural and psychological processes - e.g., imagination, counterfactual thinking, wonder, play, inspiration, and many others - that define our engagement with new possibilities in domains as diverse as the arts, architecture, design, education and business.
