Previous chapters considered value theories of psychology, sociology, anthropology, and philosophy. These disciplines can benefit and learn from one another, and closer interaction between disciplines will lead to better value theory. To facilitate an interdisciplinary understanding of value, this chapter will highlight the overlap between the different disciplines and what they can learn from one another. Each section of this chapter compares two disciplines and highlights overlaps, similarities, and differences. The hope is that this constructive comparison will build a bridge between disciplines, which helps to advance the theory development within the disciplines and brings theoretical blind spots into focus. Bringing disciplines together is the first step towards crossing disciplinary boundaries, resolving conceptual differences, and increasing interdisciplinary communication.
