This collection has its origins in four interdisciplinary workshops, one held annually at the Berlin School of Mind and Brain from 2010-2012 (Origins of Self-Consciousness I-III, Workshop on Pre-Reflective Self-Consciousness), and one at the Zentrum für interdisziplinäre Forschung (ZiF) in Bielefeld in 2013 (Self-Representationalism, Pre-Reflectivity, and Mental Impairment). This original interdisciplinary approach, especially the dialogue with neuroscientists and psychiatrists, has been retained in this collection. However, the collection has been enlarged by a number of solicited contributions that highlight special aspects of the core theme: self-consciousness.
