The tension between experienced subjectivity and its biological basis is at the core of recent philosophical, psychological, sociological, biological and interdisciplinary debates. The traditional Cartesian inner theatre and the resulting substance dualism cannot be made to fit scientific requirements. Reductive accounts, claiming some identity between mental and physical occurrences, display difficulties when it comes to accounting for the experiential dimension of human life. The central question is: What is a subject and how does a subject interact with others? This book is a collection of papers that provides innovative and insightful answers to this question. It is, therefore, as its name suggests, a discussion of subjectivity and the social world.
