Christopher Maloney offers an explanation of the fundamental nature of thought. He posits the idea that thinking involves the processing of mental representations that take the form of sentences in a covert language encoded in the mind. The theory relies upon traditional categories of psychology, including such notions as belief and desire. It also draws upon and thus inherits some of the problems of artificial intelligence which it attempts to answer, including what bestows meaning or content upon a thought (...) and what distinguishes genuine from simulated thought.

Thought, including conscious perception, is representation. But perceptual representation is uniquely direct, permitting immediate acquaintance with the world and ensuring perception's distinctive phenomenal character. The perceptive mind is extended. It recruits the very objects perceived to constitute self-referential representations determinative of what it is like to perceive.

The Representational Theory of the Mind allows for psychological explanations couched in terms of the contents of propositional attitudes. Propositional attitudes themselves are taken to be relations to mental representations. These representations (partially) determine the contents of the attitudes in which they figure. Thus, Representationalism owes an explanation of the contents of mental representations. This essay constitutes an atomistic theory of the content of formally or syntactically simple mental representation, proposing that the content of such a representation is determined by (...) the intersection of the representation's correlational and control properties. The theory is distinguished from standard information-based accounts of mental content in allowing that the relevant correlations be contingent while insisting on an efferent aspect to mental content. The theory on offer allows for a natural explanation of misrepresentation, finds a niche for the notion of narrow content, welcomes radical first person fallibility with respect to questions of content, admits of mental ambiguity and recognizes that the future of a psychological agent is a factor in determining the content of the agent's present psychological states.

An account of the contents of the propositional attitudes is fundamental to the success of the cognitive sciences if, as seems correct, the cognitive sciences do presuppose propositional attitudes. Fodor has recently pointed the way towards a naturalistic explication of mental content in his Psychosemantics (1987). Fodor's theory is a version of the causal theory of meaning and thus inherits many of its virtues, including its intrinsic plausibility. Nevertheless, the proposal may suffer from two deficiencies: (1) It seems not to (...) provide an adequate explanation of misrepresentation. (2) It may also fail, as a species of empiricism, to provide a correct explication of the content of observational concepts and those non-observational concepts whose meaning is to be traced to their causal connections with observational concepts.

J. Christopher Maloney argues that free will is compatible with necessary laws of science and immutable history. For free will emerges from an akratic will that asymptotically approaches the ability to choose to act otherwise than it willfully does.

Alfred Marshall was the most retiring and unworldly of all the great economists. Yet, he used his reign as Professor of Political Economy at Cambridge to construct for himself an overbearing economic orthodoxy not just around his own theories but also around his vision of the economics of the future. Dr Maloney's study of the Marshallian establishment sheds much light on how, and why, early in the twentieth century, one set of economic ideas came to exert a dominant influence (...) which has persisted. It will prove essential reading for historians of economics and for those interested more generally in the history of ideas. (shrink)

The task of this paper is to clarify the status and implications of Levinas's insistence on the necessity of subjectivity to the ethical relation. Focusing in particular on the discussion of substitution in Otherwise than Being, it is argued that the description of subjectivity as substitution enables Levinas to articulate the necessity of the subject to the approach of the other in a manner which avoids the transcendental character which such claims to necessity usually embody. This argument proceeds from an (...) initial characterization of substitution within the constellation of themes pursued by Levinas in Otherwise than Being to a detailed examination of the first four sections of the Substitution chapter. The essay concludes by noting the unity of the ethical exceeding of the transcendental character of subjectivity with the project which animates Levinas's work from its beginnings: the exceeding of the ontological by the ethical.

The Representational Theory of the Mind arises with the recognition that thoughts have contents carried by mental representations. For Abelard to think, for example, that Pegasus is winged is for Abelard to be related to a MENTAL REPRESENTATION whose content is that Pegasus is winged. Now, there are different kinds of representations: pictures, maps, models, and words ‐ to name only some. Exactly what sort of REPRESENTATION is mental representation? (see imagery; connectionism.) Sententialism distinguishes itself as a version of rep‐resentationalism (...) by positing that mental representations are themselves linguistic expressions within a ‘language of thought’ (FODOR, 1975, 1987; Field, 1978; Maloney, 1989). While some sententialists conjecture that the language of thought is just the thinker's spoken language internalized (Harman, 1982), others identify the language of thought with Mentalese, an unarticulated, internal language in which the computations supposedly definitive of cognition occur. Sententialism is certainly a bold and provocative thesis, and so we turn to the reasons that might be offered on its behalf. (shrink)

Byrne & Hilbert propose that color can be identified with explicit properties of physical surfaces. I argue that this claim must be qualified to take into account constraints needed to make recovery of surface color information possible. When these constraints are satisfied, then a biological visual system can establish a correspondence between perceived surface color and specific surface properties.

THE problem of universals has been with us at least since the time of Plato and it is no surprise that the first solution was what can be termed a realist one. Not a few have argued that there is something commonsensical about the claim that we call some things by a common term because it seems quite plausible that there are kinds of things and that they are not entirely the creations of our minds. The path of realism has (...) been trodden by many notables, and current literature calls attention to the fact that, in spite of all its problems, the realist view still has its own appeal. This is true now and is even more easily documented for the thirteenth century when the question of the ontological status of universals was fiercely debated in the young universities of Europe. Roger Bacon was beginning his teaching career at the University of Paris in the early 1240s and an inspection of his works reveals that on three occasions he entered the debate ex professo, namely, in his Questiones supra libros prime philosophie Aristotelis, in his Questiones altere supra libros prime philosophie Aristotelis, and in the Liber primus communium naturalium Fratris Rogeri. Hence it is in these that we should look to discover whether he was a nominalist, a moderate realist, or an extreme realist, or indeed whether he developed a position uniquely his own. (shrink)

In this paper, we argue that deliberative democrats have too narrow a conception of the political, but that 'activism' as it is normally understood is not sufficiently broad, either. Politics is not reducible to coercion and contestation, but rather to the constitution of our shared world. We contend that active citizenship more often takes the form of working in a rape crisis center or a domestic violence clinic than participating in marches or town meetings.

Metaphors are expressions in artificial, contrived, alien languages, and we understand metaphors by constructing translation schemes linking our natural, literal languages to these theoretically contrived metaphorical languages. The relation between a literal natural language and a metaphorical contrived language is like the relationship between a natively known language and a system of subsequently acquired languages etymologically emerging from that basic natural language. This model for understanding metaphorically contrived language is kin to the familiar model explaining how speakers of a language (...) such as Latin may come to decipher a language like Spanish through projecting to Spanish what they know of Latin without the aid of a translation manual. A metaphor is, thus, seen as a sentence in a nonnatural language, itself derived from and at least partially translatable with the natural, literal language of the metaphor's author or audience.

Variations in levels of apolipoprotein E have been tied to the risk and progression of Alzheimer's disease . Our group has previously compared and contrasted the promoters of the mouse and human ApoE gene promoter sequences and found notable similarities and significant differences that suggest the importance of the APOE promoter's role in the human disease. We examine here three specific single-nucleotide polymorphisms within the human APOE promoter region, specifically at -491 , -427 , and at -219 upstream from the (...) +1 transcription start site. The -219 and -491 polymorphic variations have significant association with instance of AD, and -491AA has significant risk even when stratified for the APOEepsilon4 allele. We also show significant effects on reporter gene expression in neuronal cell cultures, and, notably, these effects are modified by species origin of the cells. The -491 and -219 polymorphisms may have an interactive effect in addition to any independent activity. DNA-protein interactions differ between each polymorphic state. We propose SP1 and GATA as candidates for regulatory control of the -491 and -219 polymorphic sites. This work's significance lies in drawing connection among APOE promoter polymorphisms' associations with AD to functional promoter activity differences and specific changes in DNA-protein interactions in cell culture-based assays. Taken together, these results suggest that APOE expression levels are a risk factor for AD irrespective of APOEepsilon4 allele status. (shrink)
