It is claimed that there are pre-objective phenomena, which cognitive science should explain by employing the notion of non-conceptual representational content. It is argued that a match between parallel distributed processing (PDP) and non-conceptual content (NCC) not only provides a means of refuting recent criticisms of PDP as a cognitive architecture; it also provides a vehicle for NCC that is required by naturalism. A connectionist cognitive mapping algorithm is used as a case study to examine the affinities between PDP and NCC.

I present an argument for an interpretation of Kant's views on the nature of the ‘content [Inhalt]’ of ‘cognition [Erkenntnis]’. In contrast to one of the longest standing interpretations of Kant's views on cognitive content, which ascribes to Kant a straightforwardly psychologistic understanding of content, and in contrast as well to the more recently influential reading of Kant put forward by McDowell and others, according to which Kant embraces a version of Russellianism, I argue that Kant's views on this topic are of a much more Fregean bent than has traditionally been admitted or appreciated. I conclude by providing a sketch of how a better grasp of Kant's views on cognitive content in general can help bring into sharper relief what is, and what is not, at stake in the recent debates over whether Kant accepts a particular kind of cognitive content—namely, non-conceptual content.

What are the prospects for a cognitive science of meaning? As stated, we think this question is ill posed, for it invites the conflation of several importantly different semantic concepts. In this paper, we want to distinguish the sort of meaning that is an explanandum for cognitive science—something we are going to call meaning—from the sort of meaning that is an explanans in cognitive science—something we are not going to call meaning at all, but rather content. What we are going to call meaning is paradigmatically a property of linguistic expressions or acts: what one’s utterance or sentence means, and what one means by it. What we are going to call content is a property of, among other things, mental representations and indicator signals. We will argue that it is a mistake to identify meaning with content, and that, once this is appreciated, some serious problems emerge for grounding meaning in the sorts of content that cognitive science is likely to provide.

I sketch an explanatory framework that fits a variety of contemporary research programs in cognitive science. I then investigate the scope and the implications of this framework. The framework emphasizes (a) the explanatory role played by the semantic content of cognitive representations, and (b) the important mechanistic, non-intentional dimension of cognitive explanations. I show how both of these features are present simultaneously in certain varieties of cognitive explanation. I also consider the explanatory role played by grounded representational content, that is, content evaluated by appeal to its truth, falsity, accuracy, inaccuracy and other relational properties.

In a number works Jerry Fodor has defended a reductive, causal and referential theory of cognitive content. I argue against this, defending a quasi-Fregean notion of cognitive content, and arguing also that the cognitive content of non-singular concepts is narrow, rather than wide.

Some years ago, Howard Wettstein provided an original defense of the New Theory of Reference (NTR), the doctrine that singular terms such as names and indexicals are directly referential terms (DRTs), contributing only their reference to the truth-conditions of the tokened sentence they occur in. Wettstein maintained that in order to be semantically adequate, NTR does not have to account for what he calls Frege’s data on cognitive significance, those puzzling facts about language that prompt one to think that meaning entails more than reference to (real) objects. He later put forward another, apparently paradoxical, thesis, namely that whatever this cognitive significance that explains Frege’s data is, it cannot be reduced to the representations one has in one’s mind. In what follows, however, I will first apply the notion of referential anaphorical transfer to mixed contexts in order to show that a New Theorist has to reject Wettstein’s initial thesis as it stands, although she may endorse a weaker version of it, one that especially tallies with his second thesis. I will further argue that, insofar as rejecting Wettstein’s initial thesis does not force the New Theorist to revert to a representional conception of cognitive significance, in particular one based on the notion of a mental file, the latter thesis is absolutely correct. It is thus fitted to become a cornerstone of the New Theory, whatever form of non-mentalistic interpretation the New Theorist might wish to give to the notion of cognitive significance.

In Reference and Reflexivity, John Perry tries to reconcile referentialism with a Fregean concern for cognitive significance. His trick is to supplement referential content with what he calls ‘‘reflexive’’ content. Actually, there are several levels of reflexive content, all to be distinguished from the ‘‘official,’’ referential content of an utterance. Perry is convinced by two arguments for referentialism, the ‘‘counterfactual truth-conditions’’ and the ‘‘same-saying’’ arguments, but he also acknowledges the force of two Fregean arguments against it, arguments that pose the ‘‘coreference’’ and the ‘‘no-reference’’ problems. He sees these as genuine problems for referentialism and does not share Howard Wettstein’s (1986) view that semantics has ‘‘rested on a mistake,’’ the mistake of thinking that semantics is obliged to come to grips with ‘‘cognitive significance’’ and, in particular, to explain the fact that coreferring terms can differ in cognitive significance and that terms lacking in reference can still have cognitive significance. Perry points out that ‘‘there is nothing in [the arguments for referentialism] to show that the official content, rather than the reflexive content, is the key to understanding the cognitive motivation and impact of utterances’’ (Perry 2001, 193).1 In other words, ‘‘a theory of direct reference provides no argument for ignoring reflexive content, and, properly understood, has no motivation for searching for such an argument.’’ Thus Perry uses the notion of reflexive content to complement referentialism with a theory of cognitive significance. Frege drew a fundamental distinction between the reference of a term and the means by which its reference is determined. In his view, however, it is not the references themselves but the means by which they are determined that enter into propositions (‘‘Thoughts’’) expressed by sentences in which the terms occur. So we might call Frege an ‘indirect reference’ theorist. Echoing the introduction to Kaplan’s ‘‘Afterthoughts’’ (1989a), Perry stresses that ‘direct’, as it occurs in ‘direct reference’, does not imply that ‘‘the mechanism of reference is unmediated by the relation of fitting identifying conditions’’ (188)..

John Perry has urged that a semantic theory for natural languages ought to be concerned with the issue of cognitive significance—of how true identity statements containing different (utterances of) indexicals and proper names can be informative, held to be unaccountable by the referentialist view. The informativeness that he has in mind—one that has puzzled Frege, Kaplan and Wettstein—concerns knowledge about the world. In trying to solve this puzzle on referentialist terms, he comes up with the notion of cognitive significance as a special kind of a second-order content which should account for cognitive significance in the former sense. Focusing on his treatment of perceptual demonstratives, I argue that he fails to do so both on the level of second-order contents containing demonstrative utterances and on the level of second-order contents containing perceptual buffers as new notions associated with the perceptions and used to temporarily store ideas we gain from the perceptions, which he holds to be causally connected to each other.
