Abstract: The book proposes a new analysis of mental causation and applies it to the problem of mental disorder and its etiology. The proposed analysis grounds mental causation in information- processing, which characterizes not only mental but also biological functions. It involves driving Brentano's thesis downwards, with the argument that biological processes have (genuine) intentionality and that there is a seamless transition through developmental biology and psychology to mature human cognition. This is primarily a philosophical and conceptual case, drawing on examples from biological and psychological research. It aims to provide a justification for, and explicit statement of the implications of, assumptions that are already commonplace in the behavioural and neurosciences. In contrast with current philosophical analyses of the role of intentionality in behaviour, the analysis shows how the conditions for intentionality in the normal case contain the conditions for disordered functioning. These proposals are worked out in relation to major areas of psychopathology, including depression, anxiety disorders, schizophrenia, and personality disorders.

Abstract: This review of Bolton & Hill's (B&H) Mind, Meaning, & Mental Disorder examines their non-reductionist yet realist position on mental content. Their arguments are compared to the writings of Dennett and Millikan, where determining function is central to determining information-processing capabilities. The normative nature of function (malfunction) is considered as is its relation to mental states more broadly. Their Wittgensteinian view of meaning as action is accepted as insightful and useful, though some questions remain about their theory of meaning and its applicability to psychological phenomena.

Keywords: meaning, function, normativity, intentionality, cause, reduction

Abstract: Derek Bolton and Jonathan Hill have embarked on an ambitious project with the purpose of arguing for the necessity of retaining both psychological and psychiatric sorts of explanations for mental disorder. This includes arguing for two distinct kinds of causation. These two kinds of causation are sometimes both required in order to explain mental disorder. In the following review I first attempt to sketch their overall project. Then I offer a criticism of their view that two notions of causality are needed in order to properly explain mental disorder.

Abstract: In their reviews of Bolton and Hill (1996) (MMMD) Griffin (2002) and Clune (2002) identify some potential problems. Griffin points out that some aspects of folk psychology may turn out to be unsupported by the science. Generally, however, MMMD does not rely on folk psychology, and indeed its theory of intentionality is explicitly applied to biological systems not only psychological, where folk or any other psychological concepts would be out of place. Clune suggests that the evolutionary analysis together with advancing knowledge and technology may make the concept of intentionality redundant. We reply that the case for intentional causality is embedded in an evolutionary perspective and that the case for intentionality in biological systems does not depend on inadequate knowledge.
