Peter Abelard (1079–1142 ce) was the most wide‐ranging philosopher of the twelfth century. He quickly established himself as a leading teacher of logic in and near Paris shortly after 1100. After his affair with Heloise, and his subsequent castration, Abelard became a monk, but he returned to teaching in the Paris schools until 1140, when his work was condemned by a Church Council at Sens. His logical writings were based around discussion of the “Old Logic”: Porphyry's Isagoge, aristotle'S Categories and (...) On Interpretation and boethius'S textbook on topical inference. They comprise a freestanding Dialectica (“Logic”; probably c.1116), a set of commentaries (known as the Logica [Ingredientibus], c. 1119) and a later (c. 1125) commentary on the Isagoge (Logica Nostrorum Petititoni Sociorum or Glossulae). In a work Abelard called his Theologia, issued in three main versions (between 1120 and c.1134), he attempted a logical analysis of trinitarian relations and explored the philosophical problems surrounding God's claims to omnipotence and omniscience. The Collationes (“Debates,” also known as “Dialogue between a Christian, a Philosopher and a Jew”; probably c.1130) present a rational investigation into the nature of the highest good, in which the Christian and the Philosopher (who seems to be modeled on a philosopher of pagan antiquity) are remarkably in agreement. The unfinished Scito teipsum (“Know thyself,” also known as the “Ethics”; c.1138) analyses moral action. (shrink)

This anthology contains ten selections on the philosophy of religion, all of which were written by English-speaking analytic philosophers. The opening selection contains the contributions of Antony Flew, R. M. Hare, and Basil Mitchell to the University discussion on theology and falsification. This first selection, written in 1951, establishes the basic problematic for the book, as indeed it has for much of the discussion of religion among analytic philosophers during the last twenty years. The next three chapters in the (...) book contain articles by I. M. Crombie, John Hick, and R. B. Braithwaite which further develop the question of the falsifiability of religious statements. These are followed by articles by J. L. Mackie and Alvin Plantinga which give contrary interpretations regarding the impact of the existence of evil upon the credibility of religious assertions. The remaining chapters contain discussions of religious belief by D. Z. Phillips and H. H. Price, and of the possibility of deciding the question of the existence of God by R. W. Hepburn and Terence Penelhum. The editor provides a helpful introduction which shows the relationships between the various articles and underscores the main contributions of each. The editor also provides a useful and ample bibliography of English-language books and articles on the philosophy of religion, most of them by analytic philosophers. The bibliography is arranged according to the subject-matter covered in the text. This is a representative and useful anthology of the analytic philosophy of religion. It makes clear what are the major questions which interest analytic philosophers of religion, what procedures these thinkers use to try to answer these questions, and what some of their answers are. The editor suggests that if there is a single lesson to be learned from his anthology, it is that the philosophy of religion demands both philosophical competence and a sympathetic understanding of the religious subject-matter. Another lesson one could easily draw from this collection is that the strength of analytic philosophy of religion lies in its logical exactitude and clarity of expression, while a major weakness is its neglect of the wealth of data regarding religion provided by phenomenology, the history of religions, and the social sciences.--H.

In this monograph R. W. Beardsmore presents a lucid and readable presentation of what he takes moral reasoning to be and what he expects moral reasoning to accomplish. It is another in the long list of works which attempt to apply later-Wittgensteinian insights to the problems of ethics. The common moves run this way: Wittgenstein insists that to say that something is justified, or to say there are justifiable reasons for some position implies some fundamental agreement in our language game. (...) Moral argumentation can only take place within the context of a shared ethical language game. This moral viewpoint invests, what appear to be facts with value. According to Beardsmore the importance of shared moral viewpoints is missed by R. M. Hare with his dichotomizing of fact and value and his insistence on a decision of principle. Beardsmore also attacks the position of Phillipa Foot whom he sees on the opposite side of the issue from Hare. He sees Foot as insisting on the necessary dependence of values upon facts, which leads to her inability to account for changing moral viewpoints. Beardsmore tries to show that these views of Foot and Hare agree at least on one point, that there must be one specific way to give reasons for moral positions and hence solve moral disputes. Beardsmore has made a significant contribution by offering an illuminating application of Wittgenstein's insights to the problems of ethical theory. If they did nothing more, these insight's would be important in so far as they help to unlock the hold that the fact-value dichotomy has imposed on ethical theory for so long.--R. F. D. (shrink)

This collection of essays in moral philosophy has as its intended mark of distinction the fact that moral problems of the moment are the themes of the essays. The chapter headings indicate this contemporary concern: Abortion, Sex, Human Rights and Civil Disobedience, Criminal Punishment, Violence and Pacifism, War and Suicide and Death. There are essays by: Paul Ramsey, Philippa Foot, Jonathan Bennett, Thomas Nagel, Sara Ruddick, Richard Wassenstrom, [[sic]] John Rawls, R. M. Dworkin, William Kneale, H. L. A. Hart, J. (...) R. Lucas, Newton Carver, Jan Narveson, G. E. M. Anscombe, R. M. Hare, R. F. Holland, Mary Mothersill. One might well be inclined to agree with the editor's opposition to such philosophizing about morality which abstracts from the moral problems of one's own life. A purely theoretical approach to the study of morality would almost appear contradictory. However, it is necessary to express grave reservations about such a collection of essays as this. While the arguments of the essays are thoughtful and somewhat uncommon, the conclusions of the essays, as a rule, do not differ from "advanced" liberal opinions. In other words, the essays do not challenge students' opinions. The reading of these essays will but confirm the young in their prejudices. The problems the essays are concerned with are real problems; and it is a defect of the book that with the single exception of the chapter on Abortion no real opposing arguments are presented.--J. W.

The heart of philosophy is metaphysics, and at the heart of the heart lie two questions about existence. What is it for any contingent thing to exist? Why does any contingent thing exist? Call these the nature question and the ground question, respectively. The first concerns the nature of the existence of the contingent existent; the second concerns the ground of the contingent existent. Both questions are ancient, and yet perennial in their appeal; both have presided over the burial of (...) so many of their would-be undertakers that it is a good induction that they will continue to do so. For some time now, the preferred style in addressing such questions has been deflationary when it has not been eliminativist. Ask Willard Quine what existence is, and you will hear that "Existence is what existential quantification expresses. "! Ask Bertrand Russell what it is for an individual to exist, and he will tell you that an individual can no more exist than it can be numerous: there 2 just is no such thing as the existence of individuals. And of course Russell's eliminativist answer implies that one cannot even ask, on pain of succumbing to the fallacy of complex question, why any contingent individual exists: if no individual exists, there can be no question why any individual exists. Not to mention Russell's modal corollary: 'contingent' and 'necessary' can only be said de dicto (of propositions) and not de re (of things). (shrink)

W. F. R. Hardie; X—Aristotle's Doctrine that Virtue is a “Mean”, Proceedings of the Aristotelian Society, Volume 65, Issue 1, 1 June 1965, Pages 183–204, https.

Aristotle maintains that every man has, or should have, a single end, a target at which he aims. The doctrine is stated in E.N. I 2. ‘If, then, there is some end of the things we do which we desire for its own sake, and if we do not choose everything for the sake of something else, clearly this must be the good and the chief good. Will not the knowledge of it, then, have a great influence on life? Shall (...) we not, like archers who have a mark to aim t, be more likely to hit upon what is right?’. Aristotle does not here prove, nor need we understand him as claiming to prove, that there is only one end which is desired for itself. He points out correctly that, if there are objects which are desired but not desired for themselves, there must be some object which is desired for itself. The passage further suggests that, if there were one such object and one only, this fact would be important and helpful for the conduct of life. (shrink)

`Folk Psychology' - our everyday talk of beliefs, desires and mental events - has long been compared with the technical language of `Cognitive Science'. Does folk psychology provide a correct account of the mental causes of our behaviour, or must our everyday terms ultimately be replaced by a language developed from computational models and neurobiology? This broad-ranging book addresses these questions, which lie at the heart of psychology and philosophy. Providing a critical overview of the key literature in the field, (...) including the seminal work of Fodor and Churchland, the author explores the classic `Frame Problem' and assesses the future prospects of cognitive science. The scope of the frame problem, touching on connec. (shrink)

G. W. F. Hegel is an immensely important yet difficult philosopher. Philosophy of Mind is the third part of Hegel's Encyclopaedia of the Philosophical Sciences, in which he summarizes his philosophical system. It is one of the main pillars of his thought. Michael Inwood presents this central work to the modern reader in an intelligible and accurate new translation---the first into English since 1894---that loses nothing of the style of Hegel's thought. In his editorial introduction Inwood offers a philosophically sophisticated (...) evaluation of Hegel's ideas which includes a survey of the whole of Hegel's thought and detailed analysis of the terminology he used.

Rapid developments in Artificial Intelligence are leading to an increasing human reliance on machine decision making. Even in collaborative efforts with Decision Support Systems (DSSs), where a human expert is expected to make the final decisions, it can be hard to keep the expert actively involved throughout the decision process. DSSs suggest their own solutions and thus invite passive decision making. To keep humans actively ‘on’ the decision-making loop and counter overreliance on machines, we propose a ‘reflection machine’ (RM). This (...) system asks users questions about their decision strategy and thereby prompts them to evaluate their own decisions critically. We discuss what forms RMs can take and present a proof-of-concept implementation of a RM that can produce feedback on users’ decisions in the medical and law domains. We show that the prototype requires very little domain knowledge to create reasonably intelligent critiquing questions. With this prototype, we demonstrate the technical feasibility to develop RMs and hope to pave the way for future research into their effectiveness and value. (shrink)

This paper investigates connectionism's potential to solve the frame problem. The frame problem arises in the context of modelling the human ability to see the relevant consequences of events in a situation. It has been claimed to be unsolvable for classical cognitive science, but easily manageable for connectionism. We will focus on a representational approach to the frame problem which advocates the use of intrinsic representations. We argue that although connectionism's distributed representations may look promising from this perspective, doubts can (...) be raised about the potential of distributed representations to allow large amounts of complexly structured information to be adequately encoded and processed. It is questionable whether connectionist models that are claimed to effectively represent structured information can be scaled up to a realistic extent. We conclude that the frame problem provides a difficulty to connectionism that is no less serious than the obstacle it constitutes for classical cognitive science. (shrink)

Does Aristotle in the Nicomachean Ethics give one consistent answer to the question what life is best or two mutually inconsistent answers? In the First Book he says that we can agree to say that the best life is eudaimonia or eupraxia but must go on to say in what eudaimonia consists. By considering the specific nature of man as a thinking animal he reaches a conclusion: eudaimonia, the human good, is the activity of soul in accordance with virtue, and (...) if there are more than one virtue in accordance with the best and most complete, and in a complete life. Aristotle states that his formula is no more than a sketch or outline, but that a good sketch is important since, if the outline is right, anyone can articulate it and supply details. He seems to be thinking here not just of the rest of his own treatise but of the work of pupils and successors; he speaks, as at the end of the Topics, of progress in a science. (shrink)

This study empirically assesses the extent to which intrinsic value theories of nature are accepted and acknowledged outside the realm of academic environmental ethics. It focuses on twenty of the largest landowning organisations in England, including both conservation and non-conservation organisations and investigates the environmental philosophical beliefs and values held by representative individuals of these groups. An in-depth interview was held with a representative from each organisation. The interviews were analysed using qualitative data analysis software and the results compared against (...) a backdrop of academic philosophical positions. The study found that an ecocentric position which acknowledges nature's intrinsic value was adopted by the majority of respondents, both from conservation and non-conservation organisations. However, it was also found that individuals felt the idea of nature's intrinsic value was generally not reflected in organisational policy. (shrink)

Most philosophers of science now believe that scientific data are theory laden, i.e., the evaluation of data is influenced by prior theoretical beliefs. Although there is historical and psychological evidence that is consistent with the theory-laden position, experimental evidence is needed to directly test whether prior beliefs influence the evaluation of scientific data. In a fully counterbalanced design, one group of subjects received evidence that dinosaurs were cold-blooded, and another group of subjects received evidence that dinosaurs were warm-blooded. The subjects (...) reported a strong belief in whichever theory they had read about. Then subjects were presented with a piece of data that supported one theory and contradicted the other theory. The identical piece of data was rated as more believable when it was consistent with the subject's theory than when it was inconsistent. These results provide clear support for the position that scientific data are theory laden. (shrink)

It should be clear that Lyell's scientific contemporaries would hardly have agreed with Robert Munro's remark that Antiquity of Man created a full-fledged discipline. Only later historians have judged the work a synthesis; those closer to the discoveries and events saw it as a compilation — perhaps a “capital compilation,”95 but a compilation none the less. Its heterogeneity made it difficult to judge as a unity, and most reviewers, like Forbes, concentrated on the first part of Lyell's trilogy. The chapters (...) on glaciation were admired by Lyell's friends but had relatively little appeal to more general readers. His discussion of the species question hedged far too much to please those who accepted the cogency of Darwin's evidence and arguments. This last section of the book blatantly lacks originality or commitment and certainly has no claim to classical status in anthropology.We are left, then, with the first twelve chapters, for it was this portion that dictated the book's title and that amassed the available evidence favoring the antiquity of the human species. Did it do anything more than marshall the evidence that others had discovered? I think not. Lyell could write with style and verve. Principles of Geology is a remarkably readable book. But Antiquity is the work of a geologist, not of a systematic student of man. Despite its occasional touches of power, it never captures the freshness and immediacy of Lubbock's Pre-historic Times nor the theoretical brilliance of E. B. Tylor's Researches into the Early History of Mankind (1865).96 Antiquity utilizes little of the comparative method whereby Lyell's contemporaries used data from modern “savagery” to elaborate the possible social functions of the prehistoric remains being uncovered. It contains little social theory and has virtually no integrated framework. Even the first twelve chapters do not really hang together. As Hooker, commenting to Darwin on Lubbock's review, sadly wrote: “Lubbock in [the] N[atural] H[istory] Review, had in a note called attention to Lyell's ... ‘doing injustice’ to Prestwich & Falconer. I modified this expression ‘injustice’ in Lubbock's paper (which was friendly and apologetic). I am deeply sorry for it, but what can one do? I do think Lyell's first XII chapters a complete mess.”97 In another letter to Darwin, Hooker described this first portion of Antiquity as “confused and confusing.”98Part of the problem, of course, lay in the subject's novelty for Lyell and for most of his contemporaries. At a deeper level, however, I believe that the book accurately reflects Lyell's uncertainties about Darwin's work and its implications for man.99 Leonard Wilson's edition of Lyell's Scientific Journals provides a unique insight into Lyell's mind during the years just before he began to write Antiquity.100 Preoccupied with the human implications of evolutionary biology, Lyell was not clear how many of those implications were compatible with his deep convictions about the dignity of man's place in the cosmos. With a certain naiveté, Lyell complained in 1873 that many of his readers had failed to see the “natural connections” among the three portions of Antiquity.101 Connections could indeed be drawn between man's antiquity and his evolutionary origins; Lyell's private Scientific Journals movingly demonstrate that he was well aware of this fact. But he never fully made the connections in his published writings. Antiquity of Man is more appropriately seen as the last gasp of the heroic period in British geology than as the opening salvo in a new, post-Darwinian anthropological synthesis. Between the founding of the Geological Society of London in 1807 and the middle of the nineteenth century, geology was recognized as one of the most exciting and innovative scientific fields in Britain.102 Lyell himself had contributed much to that drama, and by the 1860's he was a public figure of venerable proportions. More then any other man he represented a geology that had extended the boundaries of process, time, and life. The fundamental achievements of Lyell and his colleagues had been assimilated into the wider Victorian consciousness, yet the earlier public debates about “genesis and geology” had left untouched in its essentials the concept of Man as a moral, responsible, created being.103Lyell never abandoned this view of his own species, and in 1863 it was a completely responsible creature which, under the weight of empirical evidence, Lyell admitted had lived on earth far longer than had previously been thought. Certainly this more generous allowance for human existence was constitutive to what Burrow calls the evolutionary social theory of midcentury Britain.104 Unlike Lyell, the younger representatives of this anthropology quietly accepted both man's antiquity and his aboriginal animality. Herbert Spencer's Principles of Psychology (1855), as well as the other volumes of his grand Synthetic Philosophy, presented as part of the cosmic process the development of human from prehuman beings.105 Tylor's discussion of what in his Researches (1865) he called the “gesture-language” presupposed the gradual and de novo origin of language in early human populations.106 Lubbock's young and polished mind was untroubled by the human implications of Darwin's work, and he cast his Prehistoric Times into such a perfect mold that it and its companionpiece (On the Origin of Civilization, 1870) went through seven editions each between 1865 and World War I, with their original theoretical structures intact. In a way that Lyell could not grasp, Lubbock was intrigued by questions concerning the origins of moral and religious beliefs and did not flinch at the thought of an amoral, atheistic creature as an ancestor.107 Indeed, as the German naturalist Carl Vogt pointed out in his Lectures on Man, translated into English the year after Antiquity, both Darwin's theories and the primitive flint knives of the Stone Age bore witness to a time beyond that imaginable from the condition of the lowest present-day “savage”:From such a low condition [little better than anthropomorphous apes], compared to which that of the so-called savages of the old and new world is a refined civilisation, has the human species gradually extricated itself, in a bitter struggle for existence, which it was well able to maintain, by being gifted with a larger amount of brain and intelligence than that possessed by the surrounding animal world.108The easy integration of biological and social themes was perhaps the distinguishing hallmark of Victorian anthropology of the 1850's and 1860's. After his fashion, Lyell got both themes into Antiquity, but he carefully separated them with a seven-chapter wall of glacial ice. Lyell's anthropology was not that of a thoroughgoing evolutionist like Lubbock, Tylor, or Spencer. For Lyell prehistoric man was not a product of biological evolution. Rude and superstitious he may have been, but he possessed ritual and a belief in a future state, and thus deserved “the epithet of ‘noble,’ which Dryden gave to what he seems to have pictured to himself as the primitive condition of our race: as Nature first made man/when wild in woods the noble savage ran.”109As a systematic argument, Lyell's book was at best a significant failure. As a popularization, it was a success — largely because of the personal stature of its author and the particular moment of its appearance. It helped establish the fact of man's antiquity with a wider Victorian audience, in itself no mean achievement. But Lyell was unable to exploit the fuller implications of his material in the service of a secular science of man. Ironically, he exploited only his colleagues' discoveries. Though the aging Lyell, with failing eyesight but unfailing mental powers, can still be seen as a man of considerable importance, his Antiquity belongs to the carefully circumscribed world of British geology rather than to the less disciplined world of Victorian anthropology.

For about a hundred years there has been an intermittent but sometimes vigorous debate1 on the question whether Quintus Smyrnaeus and Tryphiodorus directly used the Second Aeneid as a source for their epic descriptions “of the capture and destruction of Troy. Heyne thought that they did not; but towards the end of the nineteenth century it appeared more likely that they did. Heinze opposed the general belief: but it was reaffirmed for Quintus by Paschal and Becker4 and for Tryphiodorus by (...) Dr. E. Cesareo on internal evidence. Meanwhile Professor Samuel E. Bassett had concluded that Quintus was not after all dependent on Vergil: and still more recently Dr. J. W. Mackail, reviewing Cesareo's monograph, has maintained with emphasis that the Aeneid is certainly not the source of the late epic. Accordingly the controversy cannot even now be considered closed.
