- Ausonio Marras (1985). The Churchlands on Methodological Solipsism and Computational Psychology. Philosophy of Science 52 (June):295-309.This paper addresses a recent argument of the Churchlands against the "linguistic-rationalist" tradition exemplified by current cognitive-computational psychology. Because of its commitment to methodological solipsism--the argument goes--computational psychology cannot provide an account of how organisms are able to represent and "hook up to" the world. First I attempt to determine the exact nature of this charge and its relation to the Churchlands' long-standing polemic against 'folk psychology' and the linguistic-rationalist methodology. I then turn my attention to the Churchlands' account of what it is for computational psychology to be methodologically solipsistic. I argue that there is no reason to suppose that methodological solipsism commits one to a purely syntactic theory of the mind (of the kind that Stephen Stich has recently advocated): the formality constraints that methodological solipsism imposes on psychological explanation do not exclude 'essential' reference to the representational content of mental states, as long as this content is construed in the 'narrow' sense. I conclude by raising a problem for computational psychology that may provide some real cause for concern.Reading list | Discuss | Edit | Categorize |My bibliography

There is a prevalent notion among cognitive scientists and philosophers of mind that computers are merely formal symbol manipulators, performing the actions they do solely on the basis of the syntactic properties of the symbols they manipulate. This view of computers has allowed some philosophers to divorce semantics from computational explanations. Semantic content, then, becomes something one adds to computational explanations to get psychological explanations. Other philosophers, such as Stephen Stich, have taken a stronger view, advocating doing away with semantics entirely. This paper argues that a correct account of computation requires us to attribute content to computational processes in order to explain which functions are being computed. This entails that computational psychology must countenance mental representations. Since anti-semantic positions are incompatible with computational psychology thus construed, they ought to be rejected. Lastly, I argue that in an important sense, computers are not formal symbol manipulators.

Discussion of Fodor's doctrine of 'methodological solipsism' and Stich's principle of autonomy' has been concerned to show that these principles are incompatible with psychological theories which appeal to states with content (e.g. beliefs and desires). Concern with these issues, and the subsequent attempt to develop a notion of 'narrow' content which is solipsistic or autonomous, has, I believe, obscured a more fundamental issue: No theory which satisfies these principles would ever be able to explain behavior under descriptions which are in fact important to psychology. But I do not simply argue that there are descriptions under which psychological theories will not in fact explain behavior; I argue that descriptions under which psychological theories do explain behavior are not compatible with solipsistic principles. I develop several thought experiments to demonstrate this.

Gibson provides a coherent and powerful alternative to the computational, information-processing, paradigm. The paper argues for two principles. Firstly, one cannot begin to understand what internal information processing an organism must accomplish until one understands what information is available to the organism in its environment. Secondly, an organism can process information by acting on or manipulating physical structures in its environment. An attempt is made to show how these principles can be extended to cognition as a whole. It is suggested that these principles may have a foundation in evolutionary biology.

The issue of methodological solipsism in the philosophy of mind and psychology has received enormous attention and discussion in the decade since the appearance Jerry Fodor's "Methodological Solipsism" [Fodor 1980]. But most of this discussion has focused on the consideration of the now infamous "Twin Earth" type examples and the problems they present for Fodor's notion of "narrow content". I think there is deeper and more general moral to be found in this issue, particularly in light of Fodor's more recent defense of his view in Psychosemantics [Fodor 1987]. Underlying this discussion are questions about the nature and plausibility of the claim that scientific explanation should observe a constraint of methodological individualism . My goal in what follows is to bring out this more general problem in Fodor's "internalist" account of the mental.

The main arguments in the paper are directed against the latter thesis, according to which internal (or autonomous or narrow) psychological states as opposed to noninternal ones suffice for explanation in psychology. Especially, feedback-based actions are argued to require indispensable reference to noninternal explanantia, often to explanatory common causes. Thus, to the extent that methodological solipsism is taken to require the truth of the Explanatory Thesis, it, too, can be regarded as untenable.

Current computational psychology, especially as described by Fodor (1975, 1980, 1981), Pylyshyn (1980), and Stich (1983), is both a bold, promising program for cognitive science and an alternative to naturalistic psychology (Putnam 1975). Whereas naturalistic psychology depends on the general scientific framework to fix the meanings of general terms and, hence, the content of thoughts utilizing or expressed in those terms, computational cognitive theory banishes semantical considerations in psychological investigations, embracing methodological, not ontological, solipsism. I intend to argue that computational psychology cannot individuate thoughts as it promises. For, semantics is fundamental in fixing an important subset of the computational relations that, according to the computational theory, are supposed both to obtain among thoughts and, thereby, to determine their identity conditions. If what I contend is correct, then contrary to what its advocates maintain, computational psychology is not preferable to naturalistic psychology as a research strategy in cognitive science.
