This volume offers interdisciplinary insight on a variety of key topics in consciousness research, with contributions from philosophers, psychologists, cognitive scientists, and historians of philosophy. It revolves around the idea that consciousness emerges from, and impacts on, our skilled interactions with the natural and social context. Section one discusses how phenomenal consciousness and subjective selfhood are grounded on natural and social interactions, and what role brain activity plays in these phenomena. Section two analyzes how interactions with external objects and other human beings shape our understanding of ourselves, and how consciousness changes social interaction, self-control and emotions. Section three provides historical depth to the volume, by tracing the roots of the contemporary notion of consciousness in early modern philosophy.
