Have we found the holy grail? Theory of mind as a unifying construct.

Theory of Mind (ToM) refers to a person's ability to understand that another person has his or her own unique way of thinking and feeling. ToM is a well-known and rapidly expanding field of research in the neurosciences, cognitive, social sciences, evolution, and brain imaging. This review article expands ToM into areas where there has not yet been research. We propose that ToM could illuminate the relationship between religion/spirituality and health, and could provide the lingua franca for the hundreds of schools of psychotherapy. We discern two different kinds of spirituality: personal versus impersonal. Empathy is central to ToM research and is also central to mental health training and practice. ToM illuminates familiar topics in a new light. For example ToM reveals a close link between psychology and spirituality in self-efficacy and locus of control research.
