ObjectiveTo prospectively study the cingulate cortex for the localization and role of the grasping action in humans during electrical stimulation of depth electrodes.MethodsAll the patients with intractable focal epilepsy and a depth electrode stereotactically placed in the cingulate cortex, as part of their pre-surgical epilepsy evaluation from 2015 to 2017, were included. Cortical stimulation was performed and examined for grasping actions. Post-implantation volumetric T1 MRIs were co-registered to determine the exact electrode position.ResultsFive patients exhibited contralateral grasping actions during electrical stimulation. (...) All patients had electrodes implanted in the ventral bank of the right cingulate sulcus adjacent to the vertical anterior commissure line. Stimulation of other electrodes in adjacent regions did not elicit grasping.ConclusionGrasping action elicited from a localized region in the mid-cingulate cortex directly supports the concept of the cingulate cortex being crucially involved in the grasping network. This opens an opportunity to explore this region with deep brain stimulation as a motor neuromodulation target for treatment in specific movement disorders or neurorehabilitation. (shrink)

We propose a model mechanism for the initiation and spatial positioning of teeth primordia in the alligator, Alligator mississippiensis. Detailed embryological studies by Westergaard and Ferguson have shown that jaw growth plays a crucial role in the developmental patterning of the tooth initiation process. Based on biological data we develop a dynamic patterning mechanism, which crucially includes domain growth. The mechanism can reproduce the spatial pattern development of the first seven teeth primordia in each half jaw of A. mississippiensis. The (...) results for the precise spatio-temporal sequence compare well with experiment. Simulation of the model also predicts that certain transplantations can alter the spatial sequence of teeth primordia initiation. (shrink)

"Contemporary" is the controlling word in the title of this book of provocative readings, but foundational ideas of a timeless stamp are also brought to bear after the reader’s attention has been captured. In the section on ethics and society, for example, some selections deal with sex, marriage, abortion, eugenics, and women’s rights, but others are archly included on free will, the good life, duty, and the nature of ethical disagreement. The nineteen philosophers whose works are excerpted for this section (...) range from Kant and Bentham in an earlier era through Bertrand Russell and A. H. Maslow of the recent past to today’s Simone de Beauvoir, A. C. Ewing, and Charles L. Stevenson, as well as younger thinkers such as Arthur C. Danto and Nicholas Rescher. The remaining sections of the book cover political problems, language and art, experience and nature, and existential, religious, and other views of the meaning of life. An article by Huston Smith on the religious import of drugs concludes the volume. The editors’ introduction describes in fresh ways what a philosophical approach to an issue is and provides a useful setting for the relevant readings which follow. In the introductions to the five sections of the book, they take a closer look at the particular areas of interest and again try to illuminate the readings, in a different way by setting before the reader the truly challenging questions with which the readings will grapple.—W.

Background: Legislation on physician-assisted suicide is being considered in a number of states since the passage of the Oregon Death With Dignity Act in 1994. Opinion assessment surveys have historically assessed particular subsets of physicians.Objective: To determine variables predictive of physicians’ opinions on PAS in a rural state, Vermont, USA.Design: Cross-sectional mailing survey.Participants: 1052 physicians licensed by the state of Vermont.Results: Of the respondents, 38.2% believed PAS should be legalised, 16.0% believed it should be prohibited and 26.0% believed it should (...) not be legislated. 15.7% were undecided. Males were more likely than females to favour legalisation . Physicians who did not care for patients through the end of life were significantly more likely to favour legalisation of PAS than physicians who do care for patients with terminal illness . 30% of the respondents had experienced a request for assistance with suicide.Conclusions: Vermont physicians’ opinions on the legalisation of PAS is sharply polarised. Patient autonomy was a factor strongly associated with opinions in favour of legalisation, whereas the sanctity of the doctor–patient relationship was strongly associated with opinions in favour of not legislating PAS. Those in favour of making PAS illegal overwhelmingly cited moral and ethical beliefs as factors in their opinion. Although opinions on legalisation appear to be based on firmly held beliefs, approximately half of Vermont physicians who responded to the survey agree that there is a need for more education in palliative care and pain management.

Under the balmy Mediterranean skies of Santa Margherita Ligure on the beautiful Italian Riviera, forty Hegelian scholars from nine countries put their heads together on the theme “Hegel’s Philosophie des subjectiven Geistes” at the Conference of the Internationale Hegel-Vereinigung, May 24–27, 1973. Enjoying the generosity of the Italian Government and the official hospitality of the Municipality of Santa Margherita, the participants heard and discussed four papers by German scholars, two each by Italians and Americans, and one each by a Dutch (...) and a French scholar. Professor Valerio Verra of the University of Rome served as host, and Professor Dieter Henrich, President of the Internationale Hegel-Vereinigung, introduced the theme of the Conference and officiated the proceedings. Chairing individual sessions and participating in the discussions were such internationally known figures as Hans-Georg Gadamer of Germany, Eric Weil and Marcel Régnier of France, W. H. Walsh and Anthony Kenny of Great Britain, and Enrico de Negri of Italy. (shrink)

In this book G. W. Leibniz presents not only his reflections on predestination and election but also a more detailed account of the problem of evil than is found in any of his other works apart from the _Theodicy_. Surprisingly, his _Dissertation on Predestination and Grace_ has never before been published in any form. Michael J. Murray's project of translating, editing, and providing commentary for the volume will therefore attract great interest among scholars and students of Leibniz's philosophy and (...) theology. Leibniz addresses such topics as free will, moral responsibility, divine causation, justice, punishment, divine foreknowledge, and human freedom, revealing crucial aspects of the genesis of his mature metaphysics and the theological motivations behind it.

What is perhaps the biggeist metaphysical question of them all was put on the agenda of philosophy by G. W. Leibniz: “Why is there anything at all?” This question is not only difficult to answer but poses difficulties in its very conception. After all, it is—or should be—-clear that such questions as “Why is there anything at all?” and “Why are things in general as they actually are?” and “Why are the laws of nature as they are?” cannot be answered (...) within the standard causal framework. For causal explanations need inputs: they are essentially transformational rather than formational pure and simple. And so, if we persist in posing the sorts of global questions at issue, we cannot hope to resolve them in orthodox causal terms. For when we ask about everything there are no issue-external materials at our disposal for giving a noncircular explanation. Does this mean that such questions are improper and should not be raised at all—that even to inquire into the existence of the entire universe is somehow illegitimate? Not necessarily. For it could be replied that the question does have a perfectly good answer, but one that is not given in the orthodox causal terms that apply to other issues of smaller scale. (shrink)

The eminent philosopher of science Carl G. Hempel, Stuart Professor of Philosophy at Princeton University and a Past President of the American Philosophical Association, has had a long and distinguished academic career in the course of which he has been professorial mentor to some of America's most distinguished philosophers. This volume gathers together twelve original papers by Hempel's students and associates into a volume intended to do homage to Hempel on the occasion of his 65th year in 1970. The papers (...) are grouped around the unifying topic of Hempel's own interests in logic and philosophy of science, the great majority dealing with issues on inductive logic and the theory of scientific explanatio- problems to which Hempel has devoted the bulk of his outstandingly fruitful efforts. With the approach of 'Peter' Hempel's 65th birthday, an editorial committee sprang into being by an uncannily spontaneous process to prepare to commemorate this event with an appropriate Festschrift. The editors were pleased to receive unfailingly prompt and efficient coopera tion on the part of all contributors. The responsibility of seeing the work through the press was assumed by Nicholas Rescher. The editors are grateful to all concerned for their collaboration.

Ulrich von Wilamowitz-Moellendorff wrote surprisingly often to British colleagues. Usually it was a matter of a letter or two. The prolonged exchange with Gilbert Murray is the exception. More typical is the brief but important one with Sir James George Frazer. Extant evidence attests that he corresponded with some forty Englishmen and Scots. I omit Anglo-Irish: J.B. Bury, J.P. Mahaffy, L.C. Purser and the papyrologist, J.G. Smily. The evidence is incomplete because most letters after the letter N were stolen (...) and burned in the Berlin winter 1945-6. A first catalogue of his British correspondents is assembled. Because of the remoteness of much published biographical material, I include references to the important published sources and occasionally publish a document which otherwise would be forgotten. For the first time Wilamowitz's influence on the English scholars of his time is precisely documented. (shrink)

nnas' article is the first of three in a "Symposium on Ancient Ethics." She begins with the observation that ancient ethics are "eudaemonist" in form. That is, they assume "that each of us has a vague and unarticulated idea of an overall or final goal in our life," which we label eudaimonia or happiness, "and the task of ethical theory is to give each person a clear, articulated, and correct account of this overall goal and how to achieve it" (p. (...) 241; Annas defends this generalization, which is controversial as applied to Stoic and Epicurean ethics, in her The Morality of Happiness [Oxford, 1993]). Furthermore, whereas modern ethical theories (e.g., those of Kant and Sidgwick) typically distinguish between "moral reasoning" and "prudential reasoning," ancient ethical theories do not. How come? One "widespread" and "traditional" view (pp. 244, 245) is that ancient ethics assimilate morality to prudence: "ethical theory guides the agent from an intuitive, restrictive view of what is in her interests (money, power) to a more expanded and elevated view (the virtues)" (p. 244). This interpretation is sometimes joined with the claim that the Greeks took for granted what Nicholas White terms "fusionism": the view that individual good is not ultimately distinct from social or collective good (p. 245). However, Annas notes, ancient Greek literature provides ample illustration that "fusionism" was not taken for granted. (shrink)

Having refuted the phlogiston theory, Lavoisier uses this second portion of his essay to expound his new theory of combustion, based on the oxygen principle. He gives a mechanistic account of thermodynamic phenomena in terms of a subtle fluid and its ability to penetrate porous bodies. He uses this hypothetical fluid to explain volume changes, heat capacity and latent heat. Beyond the three types of combustion that he distinguishes and defines, Lavoisier also explains other chemical sources of heat, such as (...) the heat of solution. (shrink)
