This book proposes a series of interconnected arguments against the view that interpersonal understanding involves the use of a 'folk' or 'commonsense' psychology. Ratcliffe suggests that folk psychology, construed as the attribution of internal mental states in order to predict and explain behaviour, is a theoretically motivated and misleading abstraction from social life. He draws on phenomenology, neuroscience and developmental psychology to offer an alternative account that emphasizes patterned interactions between people in shared social situations.
