The ArgumentThis paper explores the confrontation of physical and contextual factors involved in the emergence of the subject of color measurement, which stabilized in essentially its present form during the interwar period. The contentions surrounding the specialty had both a national and a disciplinary dimension. German dominance was curtailed by American and British contributions after World War I. Particularly in America, communities of physicists and psychologists had different commitments to divergent views of nature and human perception. They therefore had to (...) negotiate a compromise between their desire for a quantitative system of description and the perceived complexity and human-centeredness of color judgment. These debates were played out not in the laboratory but rather in institutionalized encounters on standards committees. Such groups constitute a relatively unexplored historiographic and social site of investigation. The heterogeneity of such committees, and their products, highlight the problems of identifying and following such ephemeral historical “actors”. (shrink)

This dissertation is a defense of a particular theory of the metaphysics of time which I call "accretivism", but which is popularly known in a form usually called the "Growing Block Theory". The goal of a metaphysics of time is to incorporate the various aspects of our temporal experience into a single, comprehensive whole. To this end I delineate five aspects of our ordinary experience of time: 1) The Tensed Aspect, in virtue of which objects are presented to us as (...) past, present, or future; 2) The Transitory Aspect, in virtue of which time passes or "flows"; 3) The Durational Aspect, in virtue of which entities have a certain temporal extent; 4) The Structural Aspect, in virtue of which entities are given as being in temporal relations to one another, and 5) The Differential-Repetitive Aspect, in virtue of which things are different from one time to another, and yet there is a certain recurrence of aspects of our experience form one time to another. I contrast the accretivist picture of time, according to which that which is past and that which is present both have ontological status, but nothing which is future has ontological status, and in which temporal passage consists in the coming-into-being of new entities at the temporal edge of reality marked by the present, with the two dominant theories of time in the contemporary literature: 1) presentism, according to which only that which is present has ontological status, and 2) four-dimensionalism, according to which time is to be understood on analogy with spatial dimensions. Accretivism, I argue, is superior to the other two views in virtue of the fact that it gives full status to both the Structural Aspect of Time, for which the presentist has difficulty accounting, and the Transitory Aspect of Time, for which the four-dimensionalist has difficulty accounting. I then defend the accretivist picture against a variety of objections that might be raised to it. (shrink)

Attempts to justify the objectivity and universality of aesthetic judgment have traditionally rested on unsupported assumptions or mere assertion. This paper offers a fresh consideration of the problem of judgments of taste. It suggests that the problem of securing universal agreement is false and therefore insoluble since it imposes an inappropriate logical criterion on the extent of agreement, which is irrevocably empirical. The variability of judgments of taste actually forms a subject ripe for inquiry by sociologists, psychologists, historians and anthropologists, (...) as well as by aestheticians. Scenic beauty provides a vivid test for the variability of these judgments. (shrink)

Within cognitive and developmental psychology, it is commonly argued that perception is the basis for object concepts. According to this view, sensory experiences would translate into concepts thanks to the recognition, correlation and integration of physical attributes. Once attributes are integrated into general patterns, subjects would become able to parse objects into categories. In this article, we critically review the three epistemological perspectives according to which it can be claimed that object concepts depend on perception: state non-conceptualism, content non-conceptualism, and (...) content conceptualism. We show that the three perspectives have problems that make perception inadequate as a conceptual basis. We suggest that the inquiry about the origin and development of object concepts can benefit from a pragmatic perspective that considers objects’ cultural functions as a conceptual foundation. We address this possibility from the theoretical framework of the pragmatics of the object, considering the importance of objects’ functional permanence. (shrink)

This paper is a commentary on the target article by Lokendra Shastri & Venkat Ajjanagadde [S&A]: “From simple associations to systematic reasoning: A connectionist representation of rules, variables and dynamic bindings using temporal synchrony” in same issue of the journal, pp.417–451. -/- It puts S&A's temporal-synchrony binding method in a broader context, comments on notions of pointing and other ways of associating information - in both computers and connectionist systems - and mentions types of reasoning that are a challenge to (...) S&A's system (amongst many other connectionist systems, recognizing that S&A's is much more capable as regards reasoning than most other contemporary systems). (shrink)

Human agents draw a variety of inferences effortlessly, spontaneously, and with remarkable efficiency – as though these inferences were a reflexive response of their cognitive apparatus. Furthermore, these inferences are drawn with reference to a large body of background knowledge. This remarkable human ability seems paradoxical given the complexity of reasoning reported by researchers in artificial intelligence. It also poses a challenge for cognitive science and computational neuroscience: How can a system of simple and slow neuronlike elements represent a large (...) body of systemic knowledge and perform a range of inferences with such speed? We describe a computational model that takes a step toward addressing the cognitive science challenge and resolving the artificial intelligence paradox. We show how a connectionist network can encode millions of facts and rules involving n-ary predicates and variables and perform a class of inferences in a few hundred milliseconds. Efficient reasoning requires the rapid representation and propagation of dynamic bindings. Our model (which we refer to as SHRUTI) achieves this by representing (1) dynamic bindings as the synchronous firing of appropriate nodes, (2) rules as interconnection patterns that direct the propagation of rhythmic activity, and (3) long-term facts as temporal pattern-matching subnetworks. The model is consistent with recent neurophysiological evidence that synchronous activity occurs in the brain and may play a representational role in neural information processing. The model also makes specific psychologically significant predictions about the nature of reflexive reasoning. It identifies constraints on the form of rules that may participate in such reasoning and relates the capacity of the working memory underlying reflexive reasoning to biological parameters such as the lowest frequency at which nodes can sustain synchronous oscillations and the coarseness of synchronization.

Because the mind is the significance of the brain and God is the significance of the mind, the concept “mind” bridges how the brain works and traditional patterns of belief. The left mind, which utilizes rational vigilance and the imperative instructions of proclamation, names and analyzes the urgently right. The right mind, which discloses the relational responsiveness of numinous presence and natural symbolism, is immersed in and integrates the ultimately real. Together they provide a typology of mind‐states with which to (...) assess regressive, functional, and creative patterns. Hand dominance, gender differences, and cultural bias qualify the use of the metaphor. (shrink)

The ArgumentIn different contexts, beginning with different concerns, Pavlov, James, and Freud tried to achieve a neurophysiological explanation of mind, and suffered defeat. James and Freud acknowledged the defeat and attempted, in radically different ways, to construct an interim psychology, hoping that neural explanation would be achieved in the future. Pavlov came to the effort in his fifties, after decades of research that took for granted a sharp separation between neurophysiology and psychology. He changed his mind as he noticed the (...) descent of his discipline from study of whole-body and organ functions to concentration on the neuron and the molecule. Pavlov thought to save the discipline from chaos by providing laws of “higher nervous activity” to serve as an organizing framework. Hence his stubborn refusal to acknowledge the obvious errors in his supposed neural explanation of conditioned reflexes. The Russian context of ideological division and extreme social conflict reinforced the unwitting retreat of Pavlov and his school into a scientistic counterculture, while claiming to be developing the ultimate neural explanation of the mind. In countries of less extreme conflicts, classical conditioning continued to be a focal point of discord between psychologists who accept the inevitability of mentalist concepts and neuroscientists who insist that they must be avoided. In any context, neural explanation of mental phenomena has been a project that is impossible to avoid and impossible to accomplish. (shrink)
