Abstract

In lieu of an abstract, here is a brief excerpt of the content:Against DefinitionEric Matthews (bio)Keywordsdefinition, mental illness, ideologyVarelius rightly says, in the very first sentence of his article, that 'The nature of mental disorder is a controversial issue.' But I do not think he recognizes just how deeply controversial it is. He hopes to be able to find a way of resolving the controversy by his chosen method, based on a consideration of 'the goals that we have in classifying certain persons as mentally disordered.' However, not only does the adoption of that method presuppose that the controversy is resoluble, it is also somewhat circular. For, to be able to set out the goals that we have in classifying some people as mentally disordered, we already have to know which persons we so classify, and so what is meant by calling them 'mentally disordered.' There are several appeals to alleged 'intuitions' and one to a 'paradigm case' in Varelius's article; but, if we had such intuitions, they would be all we needed to define the concept of mental disorder, and there would be no need for the further reference to our goals in demarcating this class of human conditions.I want to argue that any alleged 'intuitions' we might have in regard to mental disorder are philosophically useless, and that the controversy about the nature of mental disorder is intrinsically irresoluble. Any claimed intuition can always be met by a rival intuition that is irreconcilable with the first. It is this, indeed, that makes the dispute about mental disorder essentially philosophical, rather than scientific, in character. Philosophical positions have to be based on, and defended by, rational argument, but there necessarily comes a point in any philosophical dispute at which no rational argument can settle the matter one way or the other. Varelius derives his methodology of considering goals of demarcation from some work done using this method on the concept of science. But people have different goals for demarcating 'science' from 'non-science' or 'pseudo-science.' The demarcation is not made, as Varelius suggests, on the basis of such criteria as testability of hypotheses or clarity of concepts; or rather, the application of these criteria themselves is determined by the goals of demarcation.The debate about what is to count as a 'science' is irresoluble in part because what we classify as such has evaluative and practical consequences. To be a 'science,' in our culture, is to be a valued activity, to have a status to be aspired to. This makes arguments about what it is to be scientific what I would like to call 'ideological' in character. Similar considerations apply to the dispute about the nature of mental disorder. Human societies have always distinguished madness from reason, disturbed or disordered behavior, thoughts, and emotions from those that are not disordered. But the purpose of making the distinction, and thus the character of the distinction made, has varied from society to society and from one historical period to another. The historian Roy Porter, in his short work Madness: A Brief History (2002) describes some of the different images of madness which have prevailed at different times in Western culture—as a divine punishment for hubris, as [End Page 53] a source of poetic inspiration, as the inevitable result of moral excess, as diabolical possession, and so on. The modern idea of mental disorder as mental illness is only one possible way of classifying together certain sorts of deviations from normality.Varelius's method of arriving at a definition of mental illness involves 'considering the goals that we have in classifying certain persons as mentally disordered.' But we can ask who are the 'we' in question, and whether 'we' have only one set of goals in classifying people in this way. The history referred to in the preceding paragraph suggests that 'we' means those members of society who do not regard themselves as disordered—the 'normal' people whose behavior can be readily understood by other normal people. Classifying someone as mentally disordered is distinguishing them as 'not one of us,' and this can serve various purposes, for instance, treating them as objects of entertainment in a human zoo, as in Bedlam; or treating them as moral...
