This book presents a unified account of the self, based on a network of knowledge sourced from several scientific accounts of selfhood. Beni constructs his ontological account of the self from the common structure that underpins the theoretical diversity that is manifested in rival and sometimes incompatible scientific accounts of the self and its aspects. The enterprise is inspired by recent structural realist theories in the philosophy of science, specifying the basic structure of the self, and explaining how representational, phenomenal, and social aspects of the self are embodied within this structure.
