H.B. Acton, professor successively in South Wales, London, and Edinburgh, died in June 1974 when he was just sixty-six. His loss is deeply lamented by his friends, not least by students of Hegel; and they extend their profound sympathy to his widow. He was much interested in political, economic and social questions, and his publications on these matters are expressive of a humane and liberal outlook. His remarkable short book on Kant’s moral philosophy shed fresh light on a well-worn topic, (...) and his posthumously printed Comte lecture on The Idea of A Spiritual Power must have many readers wish that he could have seen his idea translated into reality. It is sad that his notes for a book on Hegel in Perspective did not reach a stage at which they could be worked up for publication, but his long preface to a translation of Hegel’s essay on Natural Law is to appear in 1975 from the University of Pennsylvania Press. Not even the shortest notice could exclude mention of his effectiveness as a teacher, his untiring devotion to his students, or the respect and admiration which in them and others he inspired.

Le volume s'enquiert des liens entre l'affectivite et l'activite philosophique. Sur le mode historique et/ou problematique il s'agit de traiter de questions telles que: Y a-t-il une ou des tonalites affectives specifiques a la philosophie: etonnement, angoisse, ennui, serenite, melancolie,...? L'activite philosophique est-elle associee a un deni de l'affectivite et sous quelles formes: nihilisme, detachement, refoulement...? Quel rapport le philosophe noue-t-il a l'ambivalence de l'affect (indecidabilite, double bind,...)? Qu'en est-il de la reception thematique de l'affectivite en philosophie: une philosophie ou (...) une phenomenologie de l'affectivite est-elle possible? Quel statut philosophique pour des sciences nouvelles - les neurosciences -qui pretendent etudier objectivement et techniquement l'affectivit. (shrink)

A unifying theory of general anesthetic-induced unconsciousness must explain the common mechanism through which various anesthetic agents produce unconsciousness. Functional-brain-imaging data obtained from 11 volunteers during general anesthesia showed specific suppression of regional thalamic and midbrain reticular formation activity across two different commonly used volatile agents. These findings are discussed in relation to findings from sleep neurophysiology and the implications of this work for consciousness research. It is hypothesized that the essential common neurophysiologic mechanism underlying anesthetic-induced unconsciousness is, as with (...) sleep-induced unconsciousness, a hyperpolarization block of thalamocortical neurons. A model of anesthetic-induced unconsciousness is introduced to explain how the plethora of effects anesthetics have on cellular functioning ultimately all converge on a single neuroanatomic/neurophysiologic system, thus providing for a unitary physiologic theory of narcosis related to consciousness.
