assumptions about the phenomena of interest with process models. Thus, phlogiston has been replaced by combustion, caloric by random thermal motion, and vital fluid by far- from-equilibrium self-reproducing organizations of process. The most significant exceptions to this historical pattern are found in studies of the mind. Here, substance assumptions are still ubiquitous, ranging from models of representation to those of emotions to personality and psychopathology. Substance assumptions do pernicious damage to our ability to understand such phenomena. In this discussion, I will focus on the problem of representation

A shift from a metaphysical framework of substance to one of process enables an integrated account of the emergence of normative phenomena. I show how substance assumptions block genuine ontological emergence, especially the emergence of normativity, and how a process framework permits a thermodynamic-based account of normative emergence. The focus is on two foundational forms of normativity, that of normative function and of representation as emergent in a particular kind of function. This process model of representation, called interactivism, compels changes in many related domains. The discussion ends with brief attention to three domains in which changes are induced by the representational model: perception, learning, and language.

In this paper I wish to address the question of the nature of psychopathology. It might naturally be felt that we already know a great deal about psychopathology, and thus that such a paper would be primarily a review and discussion of the literature; I will argue, however, that the most fundamental form of the question concerning the nature of psychopathology is rarely posed in the literature, that it is prevented from being posed by presuppositions inherent in standard theoretical approaches, and that, on those rare occasions when it does get addressed, it has received inadequate answers. Therefore, the paper will have more of the character of a conceptual explication and theoretical exegesis than it will of a review of the literature.
