The close relationship between motion (bodily movement) and emotion (feelings) is not an etymological coincidence. While moving ourselves, we move others; in observing others move – we are moved ourselves. The fundamentally interpersonal nature of mind and language has recently received due attention, but the key role of (e)motion in this context has remained something of a blind spot. The present book rectifies this gap by gathering contributions from leading philosophers, psychologists and linguists working in the area. Framed by an introducing prologue and a summarizing epilogue (written by Colwyn Trevarthen, who brought the phenomenological notion of intersubjectivity to a wider audience some 30 years ago) the volume elaborates a dynamical, active view of emotion, along with an affect-laden view of motion – and explores their significance for consciousness, intersubjectivity, and language. As such, it contributes to the emerging interdisciplinary field of mind science, transcending hitherto dominant computationalist and cognitivist approaches.
