We tested the hypothesis that perception of an alternative image in ambiguous figures would be manifest as high-frequency (gamma) components that become synchronized over multiple scalp sites as a ''cognitive binding'' process occurs. For 171 combinations of data from 19 electrodes, obtained from 17 subjects and 10 replicate stimuli, we calculated the difference in correlation between the response to first seeing an ambiguous figure and when the alternative percept for that figure became consciously realized (cognitively bound). Numerous statistically significant correlation (...) differences occurred in all frequency bands tested with ambiguous-figure stimulation, but not in two kinds of control data (a reaction-time test to sound stimuli and a no-task, mind-wandering test). Statistically significant correlation changes were widespread, involving frontal, parietal, central, and occipital regions of both hemispheres. Correlation changes were evident at each of five frequency bands, ranging up to 62.5 Hz. Most of the statistically significant correlation changes were not between adjacent sites but between sites relatively distant, both ipsilateral and contralateral. Typically, these correlation changes occurred in more than one frequency band. These results suggest that cognitive binding is a distinct mental state that is reliably induced by ambiguous-figure perception tasks. Coherent oscillations at multiple frequencies may reflect the mechanism by which such binding occurs. Moreover, different coherent frequencies may mediate different components of the total cognitive-binding process. (shrink)

This two-volume work is a comprehensive reader in modern philosophical and theological hermeneutics. David E. Klemm has selected essays representing acknowledged classics in hermeneutics and the best modern hermeneutical thinkers. Volume One collects essays on the hermeneutics of texts. Volume Two collects works on the hermeneutics of existence. Each essay is preceded by an informative contextualizing introduction. Volume Two includes essays by: F. Schleiermacher, W. Dilthey, E. Husserl, M. Heidegger, R. Bultmann, P. Tillich, P. Ricoeur, J. Habermas, H-G. Gadamer, (...) and R. Scharlemann. (shrink)

Eric Olsen argues from the fact that we once existed as fetal individuals to the conclusion that the Standard View of personal identity is mistaken. I shall establish that a similar argument focusing upon dead people opposes Olson’s favored Biological View of personal identity.

The paper „F. W. Bessel and Russian science by K. K. Lavrinovich published in NTM-Schriftenreihe contains several errors coming mainly from re-translations of German names and texts from Russian into German. The correct spelling of names and original texts are given here. Beside this, some additional information from sources not mentioned by the author is presented, and the kind of relationship between Bessel and W. Struve is discussed on the basis of their correspondence.

In The Nature of Necessity, Alvin Plantinga asserts that “the number 7 exists necessarily and Socrates does not.” This is, to my way of thinking, reasonable enough. Unhappily, cannot be reconciled with Plantinga's further claims that an object x has a property P essentially or necessarily if and only if x has P in every world in which x exists and existence is itself, although not “an ordinary property,” nevertheless a property.

Modal properties are notorious epistemic trouble-makers. That theme is very much at the heart of Michael Rea’s thesis that the Discovery Problem (roughly, the problem of explaining how we know when ascriptions of modal properties are true) has no naturalistic resolution. That might encourage the thought that supernaturalism will somehow resolve the problem. This paper argues that supernaturalism is unlikely to offer a solution of the Discovery Problem.

Notre époque, traversée de courants mystiques, manifeste un intérêt tout particulier pour les idées du neo-platonicien Plotin. Pour le platonicien l'univers participe à l'idée. Platon considérait les choses comme le reflet de l'idée, ce que Plotin se refusait à admettre. La diversité dont la vie fait preuve atteste son inépuisable richesse, et si les choses dans leur état particulier sont imparfaites et défectueuses, c'est que chaque chose représente sa particularité d'une façon imparfaite. Le dualisme platonicien se retrouve chez Plotin; à (...) côté du monde de l'erreur et de l'apparence il situe celui de la vérité et de la réalité. Mais l'ordre des deux mondes étant différent, nécessairement les catégories qui y règnent diffèrent. Contrairement au monde du temps et de l'espace, où tout est désaccord et combat, l'accord et l'harmonie règnent dans le monde de l'idée. D'après Platon l'idée de l'être implique l'idée du repos. Pour Plotin le mouvement et le repos ne sont pas incompatibles. Il y a encore un point de divergence entre les deux philosophes. Tandis que Platon conçoit le bien comme idée, Plotin le superpose au monde des idées et l'en sépare. A l'oppossé du maître il n'était pas dualiste mais moniste. La conception platonicienne du bien est purement éthique, c.a.d. humaine, la conception de Plotin est plus cosmique. L'univers lui apparaît comme une trinité: le monde sensoriel, le monde idéal et l'unité suprême, et il leur découvre une base commune. Tout en admettant l'imperfection du monde, Plotin nie qu'il soit mauvais et méprisable. Il se tourne contre les Gnostiques chrétiens qui prêchent le mépris du monde, et s'oppose vigoureusement aux doctrines qui font des jouissances sensuelles l'unique but de la vie. L'exercice de la vertu n'est autre chose que le moyen de s'unir à Dieu. Pour Plotin la vertu n'est donc pas une fin en elle-même, mais elle est subordonnée à un but qui la dépasse. (shrink)

By an incomplete sentence we shall understand a declarative sentence that can be used, without variation in its meaning, to make different statements in different contexts. Although the point deserves supporting argument, which we will not provide, sentences whose grammatical subjects are indexical expressions or demonstratives are obvious, plausible examples of incomplete sentences. Uttered in one context the sentence ‘He is ill’ may be used to make one statement, for example, that George is ill, while in another context the very (...) same sentence may be used to make a quite different statement, for example, that Paul is ill.

Two recent papers by Michael Burke bearing upon the persistence of people and commonplace things illustrate the fact that the quest for synchronic ontological economy is likely to encourage a disturbing diachronic proliferation of entities. This discussion argues that Burke’s promise of ontological economy is seriously compromised by the fact that his proposed metaphysic does violence to standard intuitions concerning the persistence of people and commonplace things. In effect, Burke would have us achieve synchronic economy (rejection of coincident entities) by (...) postulating strongly counterintuitive transtemporal claims of numerical diversity. The argument is made that the price of Burkean economy is too high. (shrink)
