Getting clear about the nature and basis of interpersonal relating is a central concern of many recent debates in the philosophy of mind. The first section of this chapter highlights some basic facts about the complexity and multifaceted character of interpersonal relating and briefly overviews some of its most prominent dysfunctions. Popular mind-minding hypotheses which claim that the dysfunctions in question are rooted in impaired capacities for attending to and attributing mental states to others are then introduced. Next, recent evidence from cognitive psychology and neuroscience with which these mind-minding hypotheses must be made compatible is summarized. The important differences between two main philosophical frameworks-frameworks that offer opposing ways of understanding the nature of mind minding capacities are then highlighted. Focusing on these differences, the final section highlights how adoption of these philosophical frameworks matters to thinking about the prognosis and strategies for the treatment of certain mental disorders.
