John Palmer develops and defends a modal interpretation of Parmenides, according to which he was the first philosopher to distinguish in a rigorous manner the fundamental modalities of necessary being, necessary non-being or impossibility, and non-necessary or contingent being. This book accordingly reconsiders his place in the historical development of Presocratic philosophy in light of this new interpretation. Careful treatment of Parmenides' specification of the ways of inquiry that define his metaphysical and epistemological outlook paves the way for detailed analyses (...) of his arguments demonstrating the temporal and spatial attributes of what is and cannot not be. An appendix presents a Greek text of the fragments of Parmenides' poem with English translation and textual notes. (shrink)

Over the past hundred years, a number of scientific investigators claim to have adduced experimental evidence for phenomena information” seems to behave like a weak signal that has to compete for the information-processing resources of the organism, a reduction of ongoing sensorimotor activity may facilitate ESP detection. Such a meaningful convergence of results suggests that psi phenomena may represent a unitary, coherent process whose nature and compatibility with current physical theory have yet to be determined. The theoretical implications and potential (...) practical applications of psi could be significant, irrespective of the small magnitude of psi effects in laboratory settings. (shrink)

In this ambitious and highly original study, McCabe presents an intricately structured argument designed to demonstrate Plato’s concern with fundamental issues of rationality and personhood. In doing so, she pursues themes announced in her Plato’s Individuals and in Form and Argument in Late Plato, a collection she co-edited with Christopher Gill. The development of her position via consideration of the philosophical importance of characterization and the dialogue form in the Theaetetus, Sophist, Statesman, and Philebus leads her to focus in particular (...) on Plato’s depiction of his predecessors. These include, firstly, the Theaetetus’s Protagoras and Heraclitean flux theorists and the Sophist’s Parmenides and materialist giants, all “mean-minded opponents” whose views threaten the very possibility of rational inquiry. Refutation of them, accordingly, is Plato’s means of establishing certain basic principles of reason. (shrink)

This study of Plato's Phaedo promotes better understanding of its arguments for the soul's immortality by showing how Plato intended them, not as proofs, but as properly dialectical arguments functioning in accordance with the method of hypothesis. Unlike the argument for the soul's immortality in the Phaedrus, which does seem intended as a proof, the Phaedo arguments are proceeding toward the first principles that could serve as the basis for a proof - the most important being an account of the (...) soul's own essential nature. This study attends to the substantial progress the Phaedo makes toward such an account. It also considers Socrates' epistemic situation in the dialogue and the problem of whether his confidence in the face of death is misplaced if his arguments have not been proofs before considering how the concluding myth draws together several of the dialogue's main themes.

© 2013 The Editors of The Philosophical QuarterlyProdicus of Ceos was a major figure of the sophistic movement in Greece during the latter part of the fifth century bc. He features in a number of Platonic dialogues in ways that suggest he was regarded by Socrates more sympathetically than the other sophists. Robert Mayhew has undertaken to present and discuss all the extant textual evidence for Prodicus’ life and thought. The presentation consists of ninety pieces of mostly Greek and some (...) Latin texts, ranging from a few lines to a few pages, accompanied by facing English translation and organized topically under four main headings—Life and Character ; Language ; Natural Philosophy, Cosmology, and Religion ; and Ethics. An introduction on Prodicus’ life and thought together with an account of the collection's organizing principles precede the texts and translations, and there follows extensive commentary...

This paper reviews the debate over the evidence for ESP provided by experiments using the ganzfeld technique, a simple method used to induce a mild altered state of consciousness. The quantitative literature review technique called meta-analysis has played a prominent role in this controversy. The first question addressed by the reviewer is whether the data establish that ESP in the ganzfeld is replicable. Issues discussed include the effect of multiple analyses, the 'file-drawer' problem and statistical errors. The second question asks, (...) if the effect is real, can it be explained by methodological artifacts? Potential flaws discussed include sensory leakage, problems of randomization and participant fraud. The reviewer's first conclusion is that the aggregate database does provide evidence for a genuine psi effect. However, heterogeneity of results across experimenters indicates that the phenomenon is not easily replicable. The second conclusion is that conventional alternative explanations offered for the observed results tend to be conceivable, but even critics sometimes agree that they are implausible. (shrink)

Anyone interested in the influence of Presocratic thought may be tempted to begin with Plato and Aristotle. There is, however, sufficient evidence of Presocratic influence among the sophists to make it clear that this temptation should be resisted. Some traces of this earlier influence may be found in Plato and Aristotle themselves, and this fact should serve as a reminder that their own involvement with Presocratic philosophy did not take place in a vacuum but will have been conditioned or mediated (...) by previous developments. This article deals with classical thinkers who interpreted, wrote about, and preserved the Presocratics, pointing out that just as one must read the Presocratics through the filters of Plato and Aristotle and their successors and commentators, Plato and Aristotle were influenced by the already burgeoning tradition of historiography that developed in the late fifth and fourth centuries.

John Palmer presents a new and original account of Plato's uses and understanding of his most important Presocratic predecessor, Parmenides. Adopting an innovative approach to the appraisal of intellectual influence, Palmer first explores the Eleatic underpinnings of central elements in Plato's middle-period epistemology and metaphysics and then shows how in the later dialogues Plato confronts various sophistic appropriations of Parmenides.

Members of the New Academy presented their sceptical position as the culmination of a progressive development in the history of philosophy, which began when certain Presocratics started to reflect on the epistemic status of their theoretical claims concerning the natures of things. The Academics' dogmatic opponents accused them of misrepresenting the early philosophers in an illegitimate attempt to claim respectable precedents for their dangerous position. The ensuing debate over the extent to which some form of scepticism might properly be attributed (...) to the Presocratics is reflected in various passages in Cicero's "Academica." In this essay, we try to get clearer about the precise nature of the Academics' historical claim and their view of the general lesson to be learned from reflection on the history of philosophy down to their own time. The Academics saw the Presocratics as providing some kind of support for the thesis that things are non-cognitive, or, more specifically, that neither the senses nor reason furnishes a criterion of truth. As this view is susceptible to both 'dialectical' and non-dialectical readings, we consider the prospects for each. We also examine the evidence for the varied functions both of the Academics' specific appeals to individual Presocratics and of their collections of the Presocratics' divergent opinions. What emerges is a better understanding of why the Academics were concerned with claiming the Presocratics as sceptical ancestors and of the precise manner in which they advanced this claim. (shrink)

Previous research suggests that implicit sequence learning is superior for believers in the paranormal and individuals with increased cerebral dopamine. Thirty-five healthy participants performed feedback-guided anticipations of four arrow directions. A 100-trial random sequence preceded two 100-trial biased sequences in which visual targets on trial t tended to be displaced 90° clockwise or counter-clockwise from those on t − 1. ISL was defined as a positive change during the course of the biased run in the difference between pro-bias and counter-bias (...) responses. It was hypothesized that this difference would be greater for believers in the paranormal than for skeptics, for those who received dopamine than for those who received placebo, and for believers who received dopamine than for the other groups. None of the hypotheses were supported by the data. It is suggested that a simple binary guessing task with a focus on prediction accuracy during early trials should be considered for future explorations. (shrink)

Pseudoscience is not an appropriate label for parapsychology. Although the noise reduction model of extrasensory perception (ESP) is explanatory only in a limited sense, research does exist addressing the correlation between ESP and altered states of consciousness (ASCs). The term anomaly is not appropriately applied to experiences such as out of body experiences (OBEs) per se, but only to the question of their source. Research on both topics should be encouraged.

Though St Kosmas the Aitolian (1714-1779) is widely acknowledged to be one of the most noteworthy educators of his era and particular social context, his relevance to our age has rarely been asserted. The present article will demonstrate that behind the Saint's undeniable success as a teacher lie a great number of pedagogical principles of universal relevance which might be readily gleaned from both his educational activities and those theories he articulates in his _Didachēs_, or_ Teachings_. Moreover, it will be (...) shown that these principles which contributed so greatly to his pedagogical prowess were not achieved accidentally. The Saint labored in learning in order to render himself a more effective educator, conscientiously and effectively blending _kath'imas_ and _exothen_ learning, which in itself represents a pedagogical principle of inestimable value.
