Gray's neuropsychological model of consciousness uses a hierarchical feedback loop framework that has been extensively discussed by many others in psychology. This commentary therefore urges Gray to integrate with, or at least acknowledge previous models. It also points out flaws in his feedback model and suggests directions for further theoretical work.

In the Critique of Pure Reason, in a chapter of the Transcendental Dialectic entitled "The Antinomy of Pure Reason," Kant addresses the question whether a thoroughgoing mechanistic determinism is reconcilable with the ascription of free agency to human beings. In the third antinomy, reason is shown to be divided against itself insofar as both of two competing, and seemingly irreconcilable claims, can be justified on independent grounds; on the one hand, the claim that everything in nature proceeds according to the (...) law of causality - that every event is determined by antecedent events and causal laws; on the other hand, the claim that agents act freely, i.e., that there are some occurrences, namely human actions, which cannot be accounted for by antecedent states or events and causal laws.

The recived view in contemporary philosophy of action, inspired and sustained largely by Donald Davidson and his followers, holds that an action is intentional if and only if it is caused in the right way by beliefs and desires. In what follows below I discuss Merleau-Ponty’s account of bodily intentionality, with the aim of showing that it offers us an account of a form of intentional behavior that cannot be understood in terms of causally efficacious mental states like beliefs or (...) desires. the aim, in short, is to show that, however things may stand with other forms of intentional behavior (deliberate action, for example), bodily intentional behavior is autonomously intentional --- it doesn’t derive its intentionality from the intentionality of mental states.

We extend the concept that life is an informational phenomenon, at every level of organisation, from molecules to the global ecological system. According to this thesis: living is information processing, in which memory is maintained by both molecular states and ecological states as well as the more obvious nucleic acid coding; this information processing has one overall function—to perpetuate itself; and the processing method is filtration of, and synthesis of, information at lower levels to appear at higher levels in complex (...) systems . We show how information patterns, are united by the creation of mutual context, generating persistent consequences, to result in ‘functional information’. This constructive process forms arbitrarily large complexes of information, the combined effects of which include the functions of life. Molecules and simple organisms have already been measured in terms of functional information content; we show how quantification may be extended to each level of organisation up to the ecological. In terms of a computer analogy, life is both the data and the program and its biochemical structure is the way the information is embodied. This idea supports the seamless integration of life at all scales with the physical universe. The innovation reported here is essentially to integrate these ideas, basing information on the ‘general definition’ of information, rather than simply the statistics of information, thereby explaining how functional information operates throughout life.

This book is the second volume of a critical edition of the writings of Thomas Reid, an edition that will include many of his manuscript remains as well as his previously published works. These volumes are intended to displace the heretofore standard 8th edition of Reid’s works edited by Sir William Hamilton. Hamilton’s edition is marred by his numerous, often intrusive, and obtuse footnotes. Reid’s spelling and punctuation were also sometimes “corrected” by Hamilton, so his edition does not present a (...) fully accurate version of the original editions whose publication was superintended by Reid. The type in the Hamilton edition is also archaic and very small, making reading the text excessively difficult. The present and subsequent volumes are intended to present canonical texts free of the flaws in the Hamilton text. This volume succeeds admirably in that project. (shrink)

This book will be received ill-naturedly by those who think that a book with such a title ought, mainly anyway, to consist of critical exegesis of the work of its philosophical heroes and/or villains on the “central themes” which Professor Bennett selects for his attention. Such readers are likely to feel that when Bennett attributes this or that view, error, or insight to one of the protagonists, he ought usually t o put the man's name in quotation marks. But such (...) a reaction to this book would be at least churlish, for Bennett explicitly eschews both historical concerns and scholarship except in the limited sense that he sometimes pays close attention to textual details.

Lehrer's “reason for writing this book is that the philosophy of Thomas Reid is widely unread, while the combination of soundness and creativity of his work is unexcelled.” The book contributes to the ongoing Reid revival. Chapter 1 presents an overview of Reid's life and works and the last, Chapter 15, gives Lehrer's appraisal of Reid's philosophy. Chapter 2, “Beyond Impressions and Ideas,” outlines Reid's “refutation of what he called the Ideal System” of impressions and ideas that dominated philosophy from (...) Descartes through Hume, and summarizes Reid's theory of the mind. The remaining chapters conduct the reader through the three books Reid published during his lifetime. There are three chapters covering the Inquiry of the Human Mind, five on the Essays on the Intellectual Powers of Man, a chapter comparing Reid on conception and evidence in the Inquiry and the Essays, and three chapters on Essays on the Active Powers of Man. The index is helpful despite occasional references to a page number larger than the number of pages. The bibliography is generally good, although, oddly, Lehrer lists the inaccessible 1937 Latin edition of Reid's important Philosophical Orations and not the English translation published by the Philosophy Research Archives in 1977 and republished by the Journal of the History of Philosophy Monograph Series early in 1989. The text is remarkably free of typographical errors, but on p. 130 Putnam's 1973 article, “Meaning and Reference,” is said to have been published in 1983. (shrink)

Thomas Reid delivered philosophical orations triennially, in Latin, at graduation ceremonies in King's College, Aberdeen, 1753-1762. Each of the four orations is a summary of Reid's views on several philosophical topics, e.g. the "laws of practising philosophy"; the philosophy of science; the "theory of ideas". This translation from the Latin text is prefaced with an historical and philosophical introduction to the thought of Reid and his school. The text is footnoted with cross-references to Reid's published writings to enable the reader (...) to compare these early expressions of Reid's philosophy with his mature thought. A thorough bibliography of the most available editions of Reid's works and of the most important modern books and articles on Reid is appended. (shrink)

Integrins are ubiquitous trans‐membrane adhesion molecules that mediate the interaction of cells with the extracellular matrix (ECM). Integrins link cells to the ECM by interacting with the cell cytoskeleton. In cases such as leukocyte binding, integrins mediate cell‐cell interactions and cell‐ECM interactions. Recent research indicates that integrins also function as signal transduction receptors, triggering a number of intracellular signaling pathways that regulate cell behavior and development. A number of integrins are known to stimulate changes in intracellular calcium levels, resulting in (...) integrin activation. Although changes in intracellular calcium regulate a vast number of cellular functions, this review will discuss the stimulation of calcium signaling by integrins and the role of intracellular calcium in the regulation of integrin‐mediated adhesion.

These two books are Volumes 1 and 2 of a three-volume work; the projected third volume, Warranted Christian Belief, has yet to be published. In the first volume, Warrant: The Current Debate, Plantinga surveys the current chaos in epistemology stemming from the breakdown of classical foundationalism and examines critically the efforts of several contemporary philosophers to introduce some order into the field, most particularly Roderick Chisholm, William Alston, John Pollock, Laurence BonJour and, to a lesser extent, others such as Richard (...) Foley, Fred Dretske and Alvin Goldman. In this volume, Plantinga is trying not only to put out of play the views he rejects but also to provide the reader with anticipations of his own views in Warrant and Proper Function. Although there is an immense amount of overlap between these books, and there is much cross-referencing, they are not continuous; each can be read entirely independently of the other. Even should, through some misfortune, the projected third volume fail to be written, these two volumes are certain to stand for a long time as exceptionally important works. Warrant and Proper Function, in particular, is likely to generate a veritable Niagara of Ph.D. theses in a field many had come to see as having reached the point of diminishing nits. (shrink)
