Classical computational modellers of mind urge that the mind is something like a von Neumann computer operating over a system of symbols constituting a language of thought. Such an architecture, they argue, presents us with the best explanation of the compositionality, systematicity and productivity of thought. The language of thought hypothesis is supported by additional independent arguments made popular by Jerry Fodor. Paul Smolensky has developed a connectionist architecture he claims adequately explains compositionality, systematicity and productivity without positing any language of thought, and without positing any operations over a set of symbols. This architecture encodes the information represented in linguistic trees without explicitly representing those trees or their constituents, and indeed without employing any representational vehicles with constituent structure. In a recent article, Fodor (1997; Connectionism and systematicity, Cognition , 62, 109-119) argues that Smolensky's proposal does not work. I defend Smolensky against Fodor's attack, and use this interchange as a vehicle for exploring and criticising the “Language of Thought” hypothesis more generally and the arguments Fodor adduces on its behalf.

Evan Thompson has written a marvelous book. Waking, Dreaming, Being blends intellectual autobiography, phenomenology, cognitive science, studies in Buddhist and Vedānta philosophy, and creative metaphilosophy in an exploration of what it is to be a person, of the nature of consciousness, and of the relation of contemplative to scientific method in the understanding of human life. I have learned a great deal from it, and the community of philosophers and cognitive scientists will be reading and discussing it for some time. But I have come to criticize Thompson, not to praise him. Here I raise a few issues regarding Thompson’s treatment of the self and the connections between his own account and the Madhyamaka and...
