All of our information about the world is derived from the function of our senses, and thus they are the principal source of all our knowledge. This was recognized explicitly by early Greek philosophers, remained an important point of discussion for nineteenth‐century philosophers, and continues to be a key issue for present‐day philosophers, psychologists, and neuroscientists. It is a key issue in cognitive science because, by initiating the processes that store and evaluate information, sensory information transmission can be considered a (...) cognitive initiator. In a very real sense, who we are and how we see the world are the result of the experiences that are mediated by our sensory systems. These are some of the reasons why the study of sensory systems has occupied such a prominent place in modern cognitive neuroscience. (shrink)

Childhood adversity is associated with altered or dysregulated stress reactivity; these altered patterns of physiological functioning persist into adulthood. Evidence from both preclinical animal models and human neuroimaging studies indicates that early life experience differentially influences stressor-evoked activity within central visceral neural circuits proximally involved in the control of stress responses, including the subgenual anterior cingulate cortex (sgACC), paraventricular nucleus of the hypothalamus (PVN), bed nucleus of the stria terminalis (BNST) and amygdala. However, the relationship between childhood adversity and the (...) resting-state connectivity of this central visceral network remains unclear. To this end, we examined relationships between childhood threat and childhood socioeconomic deprivation, the resting-state connectivity between our regions of interest (ROIs), and affective symptom severity and diagnoses. We recruited a transdiagnostic sample of young adult males and females (n= 100; mean age = 27.28,SD= 3.99; 59 females) with a full distribution of maltreatment history and symptom severity across multiple affective disorders. Resting-state data were acquired using a 7.2-min functional magnetic resonance imaging (fMRI) sequence; noted ROIs were applied as masks to determine ROI-to-ROI connectivity. Threat was determined by measures of childhood traumatic events and abuse. Socioeconomic deprivation (SED) was determined by a measure of childhood socioeconomic status (parental education level). Covarying for age, race and sex, greater childhood threat was significantly associated with lower BNST-PVN, amygdala-sgACC and PVN-sgACC connectivity. No significant relationships were found between SED and resting-state connectivity. BNST-PVN connectivity was associated with the number of lifetime affective diagnoses. Exposure to threat during early development may entrain altered patterns of resting-state connectivity between these stress-related ROIs in ways that contribute to dysregulated neural and physiological responses to stress and subsequent affective psychopathology.

Some students do not cheat. Students high in measures of bravery, honesty, and empathy, our defining characteristics of heroism, report less past cheating than other students. These student heroes also reported that they would feel more guilt if they cheated and also reported less intent to cheat in the future than nonheroes. We find general consensus between students and professors as to reasons for the nonreporting of cheating, suggesting a general impression of insufficient evidence, lack of courage, and denial. Suggested (...) interventions in academia are based in positive psychology and an understanding of academic heroes. (shrink)

Many readers have suspected that Hegel---in arguing against Kant’s individualistic and critical way of approaching ethics and favoring instead an “ethical life” he associates with custom and habit---is in effect eliminating both individual judgment and any basis for criticism of corrupt or unjust communities. Most specialists reject this view of Hegel’s ethical theory, but they haven’t explained precisely how, on the contrary, ethical life preserves individual judgment and criticism within a new way of thinking about ethics.

© 2017. The American Astronomical Society. All rights reserved.We present new observations of the low-mass companion to HD 984 taken with the Gemini Planet Imager as a part of the GPI Exoplanet Survey campaign. Images of HD 984 B were obtained in the J and H bands. Combined with archival epochs from 2012 and 2014, we fit the first orbit to the companion to find an 18 au orbit with a 68% confidence interval between 14 and 28 au, an eccentricity (...) of 0.18 with a 68% confidence interval between 0.05 and 0.47, and an inclination of 119°with a 68% confidence interval between 114°and 125°. To address the considerable spectral covariance in both spectra, we present a method of splitting the spectra into low and high frequencies to analyze the spectral structure at different spatial frequencies with the proper spectral noise correlation. Using the split spectra, we compare them to known spectral types using field brown dwarf and low-mass star spectra and find a best-fit match of a field gravity M6.5 ±1.5 spectral type with a corresponding temperature of K. Photometry of the companion yields a luminosity of log=2.88 ± 0.07 dex with DUSTY models. Mass estimates, again from DUSTY models, find an age-dependent mass of 34 ±1 to 95 ±4 M Jup. These results are consistent with previous measurements of the object. (shrink)

This book provides a lucid commentary on Hegel’s Philosophy of Right and on Hegel’s other major writings on ethics and politics. Since it is the only commentary in English that covers the Philosophy of Right almost section by section, from start to finish, and it also carries on an instructive dialogue with many of the other commentaries published in recent years, it will be very useful to students and to scholars who aren’t specialists in Hegel. Although Franco can’t, of course, (...) afford to go into great detail on all of the many issues that he deals with, his judiciousness and wide reading in Hegel enable him to clarify a remarkable number of them, especially in the domain of “ethical life”. His discussions of Hegel’s conceptions of the state and of war and international relations are especially well balanced, neither avoiding difficulties nor abandoning Hegel to his legions of critics. His treatments of Hegel’s earlier works—especially the Jena lectures and the relevant portions of the Phenomenology of Spirit—are also quite helpful. Only readers who have themselves attempted to reconcile these disparate and dense texts and to reconstruct some of Hegel’s major arguments in ordinary language will fully appreciate how much Franco has accomplished.

For close to forty years now T.M. Scanlon has been one of the most important contributors to moral and political philosophy in the Anglo-American world. Through both his writing and his teaching, he has played a central role in shaping the questions with which research in moral and political philosophy now grapples. Reasons and Recognition brings together fourteen new papers on an array of topics from the many areas to which Scanlon has made path-breaking contributions, each of which develops a (...) distinctive and independent position while critically engaging with central themes from Scanlon's own work in the area. Contributors include well-known senior figures in moral and political philosophy as well as important younger scholars whose work is just beginning to gain wider recognition. Taken together, these papers make evident the scope and lasting interest of Scanlon's contributions to moral and political philosophy while contributing to a deeper understanding of the issues addressed in his work.

T. M. Scanlon's magisterial book What We Owe to Each Other is surely one of the most sophisticated and important works of moral philosophy to have appeared for many years. It raises fundamental questions about all the main aspects of the subject, and I hope and expect that it will have a decisive influence on the shape and direction of moral philosophy in the years to come. In this essay I shall focus on four sets of issues raised by Scanlon's (...) systematic argument, with the aim of clarifying some of Scanlon's central assumptions and presenting alternatives at several key points. The perspective from which I offer these comments is that of a reader who is sympathetic to Scanlon's general approach but not yet convinced on various points of detail. (shrink)

According to T. M. Scanlon's buck‐passing account, the normative realm of reasons is in some sense prior to the domain of value. Intrinsic value is not itself a property that provides us with reasons; rather, to be good is to have some other reason‐giving property, so that facts about intrinsic value amount to facts about how we have reason to act and to respond. The paper offers an interpretation and defense of this approach to the relation between reasons and values. (...) I start by acknowledging the role that substantive values play in specifications of our reasons, noting that this poses an apparent challenge to the buck‐passing account. The challenge can be met, however, if we adopt a deliberative understanding of substantive value, an interpretation that I proceed to develop and defend. In conclusion I consider recent attempts to capture the agent‐relativity of reasons within a teleological framework for thinking about the relation between reasons and values. I argue that these approaches rest on a deliberative understanding of value; the teleological framework thus turns out to illustrate the basic insight of the buck‐passing approach, rather than offering an alternative to it.

Robert Caponigri. Pp. xv+363. $12.00. These five large volumes deserve special recognition for excellence of content, range of history, and usefulness of design. Though they are intended particularly for English-speaking students and though the references are largely to recent works in English accessible to students and teachers, the range of subject-matter is international and comprehensive (for the West) and the detailed treatment of philosophers and philosophical literature is amazing for scholarly, objective clarity and wealth of information. The authors state their general aim: Our basic reason for undertaking the authorship of this work is to promote the return of the history of philosophy to its rightful place of honor and usefulness in the academic program.... Philosophy cannot be pursued in an historical vacuum.... For this reason, in these volumes the chief architectural principle has been to place philosophy as firmly as possible in the cultural context, seeing it in this living relation to all interests of culture and the hfe of the spirit. Introduction, p. xiii. Such history is so evidently needed and so generally welcome that all will surely join in urging the publisher to make these volumes available in paperback for textbook use as soon as possible. About all we can attempt here is to call attention to a few features of this history that are usually neglected in less detailed, less comprehensive histories. Vol. I foUows the usual pattern of Ancient History. Plato and Aristotle dominate, as they must. Plato's Dialogues are analyzed in considerable detail and are arranged around "the crisis in Plato's thought" as a convenient way to separate the Socratic [1071 10S HISTORY OF PHILOSOPHY dialogues from the varied compositions that seem to get away from both Socrates and Plato. Aristotle is treated well but tersely in view of the encyclopedic range of his interests and ideas. His "first philosophy" is properly so called here instead of by the unfortunate name, "metaphysics." At the end of the volume there are a few pages on Neoplatonism after Plotinus, chiefly to indicate that it wandered from philosophy. Vol. II is especially noteworthy for its description of philosophy in a great variety of distracting environments. Augustine, for example, is presented here primarily as a philosopher, even in terms of his faith and theology. For example: At the same time I was preparing for baptism at Milan, I tried to write books on the arts (disciplinae).... I was able to finish only a work on grammar.... six volumes on music... I had only begun them at Milan. Of the other five arts begun in Africa... on dialectic, on rhetoric, on geometry, on arithmetic, on philosophy. Retractationes. The passage certainly assumes that there are seven such arts, but it is noteworthy that "philosophy" takes the place usually occupied by astronomy. It has been plausibly suggested that this is a quite conscious substitute by Augustine prompted by his abhorrence of what we would nowadays call astrology (pp. 13-14). In his concluding remarks on Augustine, Professor McInerny says: Augustine's influence on subsequent ages is due entirely to the force of his thought.... The influence he had on the thought of his own times is as nothing compared with the undiminishinginfluence he has had through the centuries, even to our own day (p. 47). Another comment by Professor McInerny is worth noting here: "Our lack of sympathy with the latter-day notion of Christian philosophy." If that phrase accurately described the philosophical contribution of... (shrink)

In lieu of an abstract, here is a brief excerpt of the content:BOOK REVIEWS 389 From the perspective of this reviewer, the presently most obvious fault in this lecture lies in Putnam's criticisms of "the coherence theorists, Ludwig, et al." (p. 97). In this criticism, it is apparently assumed that the adequacy of their proposed solution to the problem considered must be judged solely on the basis of what is presently known. Since Putnam himself acknowledges that no satisfactory interpretation of (...) quantum mechanics exists, this seems unwarranted. The superficiality of the criticism of this position makes this particularly notable. He states, for example, "to say that a wave gives an incomplete description of the state of a system is to say that systems whose state can be described by that wave function may really be in several quite different physical conditions." He then adopts the doubtful strategy of appealing to the meaning of completeness and incompleteness (they are not a matter of degree) in justification of the position that it is improper to say that a wave gives an incomplete descriptionl Despite the fact that, taken as a whole, his brief criticism of the coherence theory is somewhat ungracious. Putnam has set forth the principle issues sur~ rounding the problem with discerning lucidity. Paul K. Feyerabend, in "Problems of Empiricism," places a revisionist's version of empiricism in a carefully developed historical perspective. Empiricism as it has been known is both incomplete and weakened by undesirable assumptions. The incompleteness is to be removed by regarding empiricism as a cosmological hypothesis concerning the relation between man and the universe. The version of empiricism thus admitted has the character of a scientific theory. The undesirable assumptions are views no longer tenable of the nature and content of what is given in sense. Feyerbend understands sensations and perceptions as indicators on a par with indications of physical instruments, and likewise in need of interpretation. A philosophical method is proposed which requires theoretical pluralism instead of the theoretical monism that is (inappropriately) the ideal of much of contemporary empiricism (p. 149). The function of theoretical alternatives is to provide the means of criticizing accepted theory, to which he accords careful historical treatment. "Low level theories" are to guide us to crucial experiments, while "high level theories" are to represent the basic element of the universe. Here again the reader will find a theme which emerges erpeatedly in these lectures. This theme might be stated as follows. Both macrocosmic and microcosmic systems must ultimately be involved in scientific explanation. The crucial problem that emerges is how these two are to be related or in some degree integrated. By the way in which he develops the role of alternative theories, Feyerabend has affirmed one of the principle theoretical components of what Hegel was minded to call metaphysics. An additional observation, for which what I have said should furnish some justification: Many points made throughout this exposition (115 pp. in length) might properly be regarded as together constituting a rapprochement of empiricism and rationalism. It may very well occur to the thoughtful reader that Feyerabend, in his reconstruction of empiricism, has come very near to conceding all that a critical rationalist could ask. Other lectures included in the book are, "The Thermodynamics of Purpose," by David Hawkins, "The Physics of the Large," by Philip Morrison, and "The Ethical Dimension of Scientific Research," by Nicholas Rescher. In the last-mentioned lecture, Professor Rescher points up some generally little understood ethical problems confronted by the scientist in the practice of his profession. DARREL E.

In an influential essay entitled Why abortion is wrong, Donald Marquis argues that killing actual persons is wrong because it unjustly deprives victims of their future; that the fetus has a future similar in morally relevant respects to the future lost by competent adult homicide victims, and that, as consequence, abortion is justifiable only in the same circumstances in which killing competent adult human beings is justifiable.1 The metaphysical claim implicit in the first premise, that actual persons have a future (...) of value, is ambiguous. The Future Like Ours argument (FLO) would be valid if “future of value” were used consistently to mean either “potential future of value” or “self-represented future of value”, and FLO would be sound if one or the other interpretation supported both the moral claim and the metaphysical claim, but if, as I argue, any interpretation which makes the argument valid renders it unsound, then FLO must be rejected. Its apparent strength derives from equivocation on the concept of “a future of value”. (shrink)

It is claimed by the future like ours anti-abortion argument that since killing adult humans is wrong because it deprives them of a future of value and the fetus has a future of value, killing fetuses is wrong in the same way that killing adult human beings is wrong. In The morality of abortion and the deprivation of futures (this journal, April 2000) I argued that the persuasive power of this argument rests upon an equivocation on the term “future of (...) value”. If the expression means “a potential future of value” then the moral claim is implausible because people do not in general have rights to what they need to fulfill their potential; if the expression means “self-represented future of value” then the argument fails because the fetus does not represent its future. Under no interpretation is the argument sound. In Deprivations, futures and the wrongness of killing (this journal, December 2001) Donald Marquis, author of the future like ours argument, responds at length to this objection. In the present essay the focus of the debate shifts to the proper interpretation of the right not to be killed. Donald Marquis argues that this liberty right entails the welfare right to the means necessary to sustain life; I argue that the right not to be killed does not entail unlimited welfare rights. On Marquis's view, the right not to be killed confers upon the fetus the right to whatever it takes to sustain life; on the view I defend, the right not to be killed does not confer upon the fetus or anyone else the right to another person's body. On Marquis's view, abortion is almost never permissible; on my view abortion is almost always permissible. (shrink)

While Wallace disagreed with Darwin that domesticates provided a great deal of useful information on wild populations,71 Darwin continued to draw on his domesticated animals and plants to inform him on the workings of his theory. Unlike Wallace, his exposure to natural populations was extremely limited after his return from the Beagle voyage. By the 1850s, he had settled into a life at Down House and was becoming more and more withdrawn from London scientific circles. He turned to (...) his network of informants, visits from colleagues such as Hooker and T. H. Huxley, subscriptions to various journals, and his own experimental studies at Down.This work on domesticates was clearly related to other natural history studies conducted by Darwin and others during the same period. For example, during the 1850s when Darwin worked on domesticates, he was also engaged in questions of geographic distribution. To study the dispersal and subsequent viability of introduced seeds, he soaked various seeds in a tub filled with seawater and counted which of the seeds floated after a given period; later he planted the seeds in the yard at Down to look for potential viability. There was no attempt at controlled, replicated experiments in these studies, or in his work with domesticates, nor should there have been. To Darwin the results of one experiment represented a potential truth of nature, and he was quick to seize upon these results as supporting evidence for his theory.I have suggested in this paper that his work on domesticates was not simply meant to provide an analogy for natural selection but rather became a research program to investigate other aspects of his natural selection theory, especially inheritance and variability; these subjects were integral parts of his theory of natural selection, but by 1859 he had not found a mechanism to account for them. The experiments brought home the difficult problems of inheritance, and Darwin specifically formulated pangenesis to account for these problems. Pangenesis was not an afterthought but an integration of several decades of thinking on inheritance. It was a unified theory to explain the complicated results he witnessed in his own experiments.Much of the Darwin scholarship has focused on Darwin's path toward the discovery of natural selection. Natural selection per se was a major interest, but not the only area of interest to Darwin. Inheritance was an area of serious concern for him both before and after he had formulated natural selection. His experimentation with domesticates was an attempt to look beyond natural selection and to concentrate on the difficult subject of inheritance. He found inheritance especially troublesome, requiring a “provisional hypothesis” to account for it. To see domesticates, as they are described in the Origin, as merely an analogy for natural selection, does not account for the importance Darwin placed on them. For him they were not man's monstrous productions, but worthy experimental subjects providing him with crucial information on inheritance. (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.

Ontological and methodological constraints on a theory of cognition that would generalize across species are identified. Within these constraints, ecological arguments for animal-environment mutuality and reciprocity and the necessary specificity of structured energy distributions to environmental facts are developed as counterpoints to the classical doctrines of animal-environment dualism and intractable nonspecificity. Implications of and for a cognitive theory consistent with Gibson's programme of ecological psychology are identified and contrasted with contemporary cognitivism.

What if human joy went on endlessly? Suppose, for example, that each human generation were followed by another, or that the Western religions are right when they teach that each human being lives eternally after death. If any such possibility is true in the actual world, then an agent might sometimes be so situated that more than one course of action would produce an infinite amount of utility. Deciding whether to have a child born this year rather than next is (...) a situation wherein an agent may face several alternatives whose effects could well ramify endlessly on such suppositions, for the child born this year would be a different person—one who preferred different things, performed different actions, and had different descendants—from a child born next year. It has recently been suggested that traditional utilitarianism stumbles on such cases of infinite utility. Specifically, utilitarianism seems to require, for its application, that all experience of pleasure and pain cease at some time in the future or asymptotically approach zero.2 If neither of these conditions holds, then the utility produced by each of two alternative actions may turn out to be infinite, and utilitarianism thus loses its ability to discriminate morally between them.

There is already a copious literature comparing Claudius' oration on the admission of the primores Galliae into the Roman Senate with Tacitus’ account of the speech and of the opposition's case in Annals 11. 23–4. Yet the Emperor's own purpose in speaking as he did still needs some illumination. Scholarly concentration on technical points about the citizenship, on Claudius’ antiquarianism and on his debt to Livy has been fruitful, but it has often distracted attention from Claudius’ immediate aim. Meanwhile, Tacitus’ (...) interpretation has been insidious in colouring our view of what course of action the imperial orator was trying to defend before the Senate. (shrink)
