We can understand viewed scenes and extract task-relevant information within a few hundred milliseconds. This process is generally supported by three cortical regions that show selectivity for scene images: parahippocampal place area (PPA), medial place area (MPA) and occipital place area (OPA). Prior studies have focused on the visual information each region is responsive to, usually within the context of recognition or navigation. Here, we move beyond these tasks to investigate gaze allocation during scene viewing. Eye movements rely on a (...) scene’s visual representation to direct saccades, and thus foveal vision. In particular, we focus on the contribution of OPA, which is i) located in occipito-parietal cortex, likely feeding information into parts of the dorsal pathway critical for eye movements, and ii) contains strong retinotopic representations of the contralateral visual field. Participants viewed scene images for 1034 ms while their eye movements were recorded. On half of the trials, a 500 ms train of five transcranial magnetic stimulation (TMS) pulses was applied to the participant’s cortex, starting at scene onset. TMS was applied to the right hemisphere over either OPA or the occipital face area (OFA), which also exhibits a contralateral visual field bias but shows selectivity for face stimuli. Participants generally made an overall left-to-right, top-to-bottom pattern of eye movements across all conditions. When TMS was applied to OPA, there was an increased saccade latency for eye movements toward the contralateral relative to the ipsilateral visual field after the final TMS pulse (400ms). Additionally, TMS to the OPA biased fixation positions away from the contralateral side of the scene compared to the control condition, while the OFA group showed no such effect. There was no effect on horizontal saccade amplitudes. These combined results suggest that OPA might serve to represent local scene information that can then be utilized by visuomotor control networks to guide gaze allocation in natural scenes. (shrink)

Evidence suggests that humans might have neurological specializations for music processing, but a compelling adaptationist account of music and dance is lacking. The sexual selection hypothesis cannot easily account for the widespread performance of music and dance in groups (especially synchronized performances), and the social bonding hypothesis has severe theoretical difficulties. Humans are unique among the primates in their ability to form cooperative alliances between groups in the absence of consanguineal ties. We propose that this unique form of social organization (...) is predicated on music and dance. Music and dance may have evolved as a coalition signaling system that could, among other things, credibly communicate coalition quality, thus permitting meaningful cooperative relationships between groups. This capability may have evolved from coordinated territorial defense signals that are common in many social species, including chimpanzees. We present a study in which manipulation of music synchrony significantly altered subjects’ perceptions of music quality, and in which subjects’ perceptions of music quality were correlated with their perceptions of coalition quality, supporting our hypothesis. Our hypothesis also has implications for the evolution of psychological mechanisms underlying cultural production in other domains such as food preparation, clothing and body decoration, storytelling and ritual, and tools and other artifacts.

There are a standard number of replies to the riddle of induction, none of which has gained ascendency. It seems that a new approach is needed that concedes less to the Humean dialectic. Humeans, both traditional and contemporary, unwittingly play on the ambiguity of the phrase "change in the course of nature," and that is why `C· ∼ E' appears to be self-consistent, though in fact it is not. I provide an analysis of 'cause' and 'natural necessity' which gives inductive (...) inference that internal warrant we assume it to have in ordinary and scientific thinking and rebut in advance contemporary Humean objections based on the erroneous assumption that 'x is necessary' and 'x is a priori' are materially equivalent.

In lieu of an abstract, here is a brief excerpt of the content:Oberlin's First Philosopher* EDWARD H. MADDEN ASA MAHANWAS THE FroST president of Oberlin College (1835-50) and professor of moral philosophy--the usual pattern during these years of "academic orthodoxy" when Christianity was purveyed in American colleges as the philosophy.1 The orthodox professors argued philosophical points very little but rather "presented" and "illustrated" their basic truths. 2 In some ways Mahan fit the stereotype. He did not always probe deeply (...) into questions or always offer reasons for his conclusions. His books are full of phrases like "it could not be otherwise", "no one, it is presumed, will deny that", "it is intuitively evident", "everyone cannot but know", and so on. And he frequently cited other philosophers, as well as the Scriptures, as "authorities." He even cited lengthy passages from Jonathan Edwards whenever he could, even though he differed with Edwards on almost every major point f In more important ways Mahan, however, does not fit the stereotype. Unlike Francis Wayland and most of the other academic orthodoxy before 1850, he had read, and been influenced by, German and French philosophers as well as the Scottish realists. Mahan was particularly influenced by Kant and Cousin. An astute contemporary reviewer remarked that Mahan, like Cousin, was an eclectic. "His eclecticism degenerates sometimes into the merely aggressive, and he delights occasionally in strange and incongruous combinations of Kant, Coleridge, Cousin and himself, but showing here and there great vigor and acuteness, and very considerable philosophical ability." a The aggressiveness of Mahan also sets him apart from the rest of the orthodoxy. He was too fiery by temperament to pass up polemics and hence got to the heart of some basic philosophical problems. He attacked the Edwardian doctrine of determinism and was led, by the vigor of his attack, into what many nineteenth-century Christians considered heresy3 He attacked utilitarianism in all its forms, including Paley's, in a far more consistent and thorough fashion than Francis Wayland and the other followers of Scottish realism and English intuitionism. And first and foremost he vigorously attacked the moral philosophy of his colleague Charles Grandison Finney, famous evangelist, professor of theology, and president-to-be of Oberlin. The spiritedness of his criticisms frequently aroused the ire of his Oberlin colleagues, but the spirited- *Research for some of the material in this paper was made possible by a grant from the Penrose Fund of the AmericanPhilosophicalSociety. ~Cf.

I Mahan's critique of Edwards appears in his Doctrine o] the Will, first published in 1844. According to Mahan, "Edwards stands convicted of a fundamental error in philosophy, an error which gives form and character to his whole workmthe confounding of the Will with the Sensibility, and thus confounding the characteristics of the phenomena of the former faculty with those of the phenomena of the latter." 5 The trouble is that the whole of Edwards' work "is constructed without an appeal to Consciousness, the only proper and authoritative tribunal of appeal in the case." 8 If we attend carefully to consciousness, said Mahan, we can distinguish volition from the strongest desire and hence must distinguish between the separate faculties of will as personal activity and sensation as mere passive impression. The latter does not "act," it merely "suffers." The will is the moving force in life and unless it can be shown that there is some necessary connection between will and sensation--which, in fact, cannot be done--then it follows that the will is free, that is, the source of "personal activity." Mahan's rejection of universal determinism, of course, entailed the rejection of the Calvinistic doctrine of election... (shrink)

Most philosophers of science nowadays hold a network or postulational view of the meaning of theoretical words. However, there are many nuances to this view, and after explicitly separating them, we show what we take to be wrong with each one. While we reject the postulational view we do not defend its traditional alternatives either; rather we show the pointlessness of insisting on a single source for the meaning of theoretical words. We also point out the shortcomings of Carnap's newest (...) meaning criterion which depends upon a network view. But, again, we suggest not only that this new rendition of the criterion is faulty but also that there is something misguided about any search at all for such a criterion. (shrink)

To begin with, there is a conceptual necessity implied in the very concept of cause itself, and in all concepts that have a causal element; and this definitional "must," far from being conventional or arbitrary, reflects the natural necessity of those physical systems which in fact constitute the nature of our universe. The conceptual necessity of the concept of cause can be pointed up in the following way. Assume that we have good reason for saying at to that f, g, (...) h, and i are jointly sufficient to E and hence C of E. What would we say at t1 if f, g, h, and i occurred but not E? We would clearly not say then, or ever, that while ordinarily these conditions are jointly sufficient for E, this time they were not; rather we would say that somehow we were mistaken in thinking that f, g, h, and i at t1 were identical with f, g, h, and i at t0. We might have been mistaken in either of two ways. We might have mis-identified one of the conditions at t1, erroneously thinking, say, that p was an f; or one or more of the conditions might have had its nature altered, losing some capacity or power it once had. In either case, we would withdraw the claim at t1 that C was the cause of E. Since we would withdraw the use of C at t1 and would never admit that f, g, h, and i at any t, if genuine instances of f, g, h, and i, would not produce E, we are clearly using C in such a way that actually producing E is part of its meaning. On the assumption that the conditions are genuinely the same, it follows, so to speak, from the principle of identity that they must produce the same effect. (shrink)

Wittgenstein's later efforts to exorcise the attractions of solipsism involve descriptions of the uses of 'I' which may be taken to show that 'I' does not refer in its philosophically most salient uses. This point of "grammar," however, would not by itself provide a direct refutation of solipsism; _Philosophical Investigations, Sections 398-410, of which this paper is a reading, traces a complex dialectic by which Wittgenstein elicits and questions the solipsist's commitments. In challenging the intelligibility of the solipsist's starting points, (...) Wittgenstein raises a forceful demand for an explanation of the motivations behind metaphysical inquiry into the nature of the self. (shrink)

Implicit in the scottish tradition is a metaphilosophy of commonsense which deserves as much attention as that recently given to scottish presentative realism and agent causality. The author articulates this metaphilosophy by (a) sketching a systematic metaphilosophy of commonsense, (b) considering to what extent thomas reid fits this pattern, And (c) deciding to what extent asa mahan, One of the ablest of the american realists, Fits it. The result is a characterization of a coherent scottish metaphilosophy still worthy of consideration. (...) He also explores the question whether the metaphilosophy that emerges from (b) and (c) is part of an ongoing tradition. It has been suggested that there are important similarities between the scottish view and g e moore's concept of analysis. While he agrees that there are analogies he stresses the disanalogies as more enlightening about the nature of both. (shrink)

Although the point of departure for Gestalt theory has been for the most part psychological investigation, nevertheless Gestalt theory is more inclusive than Gestalt psychology. Within psychology Gestalt theory claims to be the basis of the only scientific theory that can explain the empirical facts of psychology, but on a more general level Gestalt theory comprehends a philosophy of science, and positions in epistemology, metaphysics, and value theory. According to Wertheimer, Gestalt theory is “a palpable convergence of problems ranging throughout (...) the sciences and the various philosophic standpoints of modern times”. He also asserts that Gestalt theory was the result of concrete work done in psychology, logic, and epistemology. In this paper we will be concerned only with the Gestaltist interpretations of and claims for the method and structure of science in general. (shrink)

What do we learn about language from reading Wittgenstein'sPhilosophical Investigations? This question gains urgency from Wittgenstein's alleged animus against philosophical theorizing and his indirectness. Section 1 argues that Wittgenstein's goal is to prevent philosophical questioning about the foundations of language from the beginning. This conception of his aim is not in tension with Wittgenstein's use of the notion of community; community interpretations of his views betray a misguided commitment to the coherence of the idea that language might need grounding. Wittgenstein's (...) goal is not to enjoin us not to step outside of language-games, but to show that we have insufficiently clear grasp of the terms we try to use to express the limits of intelligibility. Section 2 suggests that appreciating Wittgenstein's moral concerning the relation between language and philosophizing about it involves allowing him to teach us how to read his book. What makes readingPhilosophical Investigations possible is openness to learning how not to forget our lives in language. (shrink)

Irregularity is fundamental to both Wright's and Peirce's positions but they interpret it in radically different ways. The occurrence of things by absolute chance, Peirce's tychism, is his explanation of irregularity; chance, for him, is ontologically irre- ducible--"an objective reality, operative in the cosmos." Wright, on the other hand, interpreted irregularity as a function of causal complexity; it does not constitute an abridgement of causality but only an abridgement of our knowledge of it.
