In this paper I argue that thinking in terms of process metaphysics and seeing the mind and mental disorders as processual in nature allows for a more complete understanding of mental disorders than is allowed by non-processual frameworks, while it also allows us to incorporate what we currently know about them. In addition, it can address problems in psychiatry that arise when we ask the wrong kinds of questions that naturally arise within a non-processual metaphysical framework. In this paper I (...) address the problems of reductionism, essentialism and dualism. -/- . (shrink)
