For years a debate has raged within the various literatures of philosophy, psychiatry, and psychology over whether, and to what degree, the concepts that characterize psychopathology are social constructions that reflect cultural values. While the majority position among philosophers has been normativist, i.e., that the conception of a mental disorder is value-laden, a vocal and cogent minority have argued that psychopathology results from malfunctions that can be described by terminology that is objective and scientific.

Such questions include the criteria for deciding that a statement represents a belief, the extent to (...) which we integrate our beliefs into a coherent web, and the nature and limits of human rationality.
