The concept of "fitness" is a notion of central importance to evolutionary theory. Yet the interpretation of this concept and its role in explanations of evolutionary phenomena have remained obscure. We provide a propensity interpretation of fitness, which we argue captures the intended reference of this term as it is used by evolutionary theorists. Using the propensity interpretation of fitness, we provide a Hempelian reconstruction of explanations of evolutionary phenomena, and we show why charges of circularity which have been levelled (...) against explanations in evolutionary theory are mistaken. Finally, we provide a definition of natural selection which follows from the propensity interpretation of fitness, and which handles all the types of selection discussed by biologists, thus improving on extant definitions.

This lecture is divided, roughly, into three parts. First, there is a general and perhaps rather simple-minded discussion of what are the ‘facts’ that social anthropologists study; is there anything special about these ‘facts’ which makes them different from other kinds of facts? It will be useful to start with the common-sense distinction between two kinds or, better, aspects of social facts; first—though neither is analytically prior to the other—and putting it very crudely, ‘what people do’, the aspect of social (...) interaction, and second, ‘what—and how—people think’, the conceptual, classifying, cognitive component of human culture. Now in reality, of course (and perhaps not so ‘of course’; people do tend to think of them as separate ‘things’), these two aspects are inextricably intertwined. But it is essential to distinguish them analytically, because each aspect gives rise to quite different kinds of problems of understanding for the social anthropologist. We shall see that the problem of how to be ‘objective’, and so to avoid ethnographic error, arises in both contexts, but in rather different forms in each. (shrink)

© 2016 Regents of the University of California.The Review summarizes much of particle physics and cosmology. Using data from previous editions, plus 3,062 new measurements from 721 papers, we list, evaluate, and average measured properties of gauge bosons and the recently discovered Higgs boson, leptons, quarks, mesons, and baryons. We summarize searches for hypothetical particles such as supersymmetric particles, heavy bosons, axions, dark photons, etc. All the particle properties and search limits are listed in Summary Tables. We also give numerous (...) tables, figures, formulae, and reviews of topics such as Higgs Boson Physics, Supersymmetry, Grand Unified Theories, Neutrino Mixing, Dark Energy, Dark Matter, Cosmology, Particle Detectors, Colliders, Probability and Statistics. Among the 117 reviews are many that are new or heavily revised, including those on Pentaquarks and Inflation. The complete Review is published online in a journal and on the website of the Particle Data Group. The printed PDG Book contains the Summary Tables and all review articles but no longer includes the detailed tables from the Particle Listings. A Booklet with the Summary Tables and abbreviated versions of some of the review articles is also available. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:?;5. HUME AND SPINOZA It is strange that there has been so little interest in comparing two great philosophers, Hume and -Spinoza, who were both so important and influential in bringing about the decline of traditional religion. Jessop's bibliography indicates no interest in Hume and Spinoza up to the 1930 's. The Hume conferences of 1976, as far as I have been able to 2 determine, avoided the topic. (...) In one of the better new Hume volumes, Livingston and King, Hume, A Re-evaluation, 3 Spinoza is cited twice, and once incorrectly at that. On the other hand, in the massive new Spinoza volume edited by Siegfried Hessing, Speculum Spinozanun 1677-1977, Hume is mentioned four times, but only one of these has any real relevance to Hume's views vis-a-vis Spinoza's. Some discussion of Hume's comments, usually brief, occurs in the commentators. B. M. Laing, in David Hume, (London 1932), has just three short references to Spinoza. John Laird, in Hume's Philosophy of Human Nature, (London 1932) has a couple of cursory references to Spinoza, plus a bit more extended statement of Pierre Bay le" s critique of him. In H. H. Price, Hume's Theory of the External World, (Oxford 1940), there is one paragraph on Hume and Spinoza. In Norman Kemp Smith, The Philosophy of David Hume (London 1941), there are three references to Spinoza. Rachel Kydd, Reason and Conduct in Hume's Treatise (Oxford 194 6), has the greatest number of references to Spinoza. She was concerned to compare him with Hume on other matters than are dealt with in this paper, namely Spinoza's theory of reason and 9 the passions. In contrast, André Leroy, David Hume, (Paris 1953), has just one paragraph on Spinoza dealing with the immateriality of the soul; and Ernest C. Mossner, in his monumental Life of David Hume, (Austin 1954), has only one reference to Spinoza - James Beattie's denunciation of Hume, Hobbes, Malebranche, Leibniz and Spinoza. Lastly, in a fairly recent commentary by James Noxon, Spinoza is mentioned 66. three times, but not for anything in Hume's text. Noxon does point out (p. 75) that Spinoza is not mentioned in ] 2 Hume's correspondence. John H. Randall has offered an explanation for this neglect of Spinoza by Hume scholars, namely that "Hume stands for all time as the antithesis of Spinoza in his thought". In the England of Hume's day, Spinoza was little known, but still better known at the time than he was in France or England. Spinoza's Tractatus Theologico-Politicus 14 had been twice translated into English anonymously. He had been attacked by Bishop Stillingfleet, by John Evelyn, by Berkeley and several others. But Spinoza was not a major figure, except to the English Deists, and to Hume's early patron, the Chevalier Andrew Michael Ramsay. Most of the information known about Spinoza came from Pierre Bayle' s Historical and Critical Dictionary, where the article "Spinoza" is the longest in the Dictionary, about three hundred pages in length. My suspicion, or hypothesis, is that Hume first became interested in Spinoza through Ramsay, and then learned what he knew about Spinoza from Bayle' s article. When the young David Hume went to France to write his A Treatise of Human Nature in 1734, he went first to see the Chevalier Ramsay, who entertained Hume for about two weeks. Ramsay was a leading Scottish Catholic, was the teacher of Bonnie Prince Charlie, a leading Scottish revolutionary, 18 as well as the Grand Master of the Free Masons. With Ramsay's eclectic views it is not odd that he had a serious interest in Spinoza's theory, and that he was composing answers to it. Ramsay advised Hume about his own book, and Hume felt he had to show Ramsay the Treatise before he 19 brought it back to England. In the Treatise there is a not too well studied section on Spinoza, Of the immateriality of the soul 20 (T240-45). In introducing Spinoza into the discussion of 67. the immateriality of the soul, Hume follows what was common practice in his day, namely to insult Spinoza and his theory... (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Joseph Priestley's Criticisms of David Hume's Philosophy RICHARD H. POPKIN ONE OF HUME'S MOST FAMOUS CRITICS, the great scientist Joseph Priestley (1733-1804), is scarcely mentioned or studied in the Hume literature.' Perhaps because of the course philosophy followed after Hume, the Scottish Common Sense critics and the German ones connected with Kant are given almost all of the attention. In this paper 1 shall try to correct this oversight, (...) and examine the background of Priestley's critique of Hume, both in terms of Priestley's scientific and religious views and in terms of Hume's influence at the time. I shall then evaluate the merits of Priestley's critique and attempt to determine whether it deserves further study or should be returned to the obscurity it has been in for almost two centuries. 2 Joseph Priestley was a nonconforming minister whose progressively radical views caused him to lose various posts. Eventually he became a millenarian, convinced that crucial signs of the end of the world were at hand: the events of the French Revolution; the purported discovery of the Lost Tribes in Afghanistan by Sir William Jones; plans or hopes for the Jews to return to Palestine and join forces with the Christians. After years of religious wanderings Priestley ended up a millenarian Unitarian, much in the tradition of Sir Isaac Newton, whose religious writing he used extensively, and of Newton's successor, William Whiston? Priestley taught science in various schools and was immensely influenced by David Hartley's Observations on Man. He found in Hartley's theory of association of ideas a naturalistic way of explaining human mental life. And in Hartley's millenarian views he located the sort of theology he was seeking. Priestly later reedited Hartley, including introductory essays about some of the more difficult aspects of his mechanistic psychology.' (Coleridge, who was deeply impressed by ' T. E. Jessop, A Bibliography of David Hume and of the Scottish Philosophy from l-)'ancis Hutcheson to Lord Balfour (New York, 1966), lists the titles of Priestley's works relevant to Hume. However, there appear to be no discussions of Priestley on Hume listed in this work or in Roland Hill, A Bibliography of David Hume from 1930 (York, 1971). E. C. Mossner, The Life of David Hume (Edinburgh, 1954), mentions Priestley's criticisms of Hume, but only as these were made in connection with criticisms of Beattie. Joseph Priestley, Memoirs of Dr. Joseph Priestley to the Year 1795, written by Himself, with a Continuation to the time of his decease by his son, Joseph Priestley, ed. T. Cooper (London, 1806). It is also of some interest that Priestley attacked Reid, Beattie, and Oswald a few years before challenging Hume. He seemed to think that he had disposed of the Scottish Philosophy for all time. Thus Priestley was certainly no part of the mainstream of Hume's opponents in Britain. See Memoirs, pp. 78-79n, and n. 16 below. ' On Priestley's career, see his Memoirs. Modern biographies deal principally with his scientific achievements and ignore or play down his theological concerns. For an extended discussion of Priestley's millenarian views, see Clarke Garrett, Respectable Folly (Baltimore, 1975), pp. 126-143. " Priestley, Hartley's Theory of the Human Mind, on the Principle of the Association of Ideas... (London, 1775). [437] 438 HISTORY OF PHILOSOPHY Hartley, probably read Priestley's edition of his works.) For the most part, Priestley wrote long and controversial works on theology. His scientific achievements stem from his friendship with Benjamin Franklin and Richard Price, who encouraged him to write a history of discoveries in electricity. Franklin provided the resources for making the equipment. On the basis of the new material in his work, Priestley was nominated to the Royal Society by Franklin and Price. s Priestley's most famous scientific works came thereafter--his discovery of oxygen and his work on how the human body used oxygen. Later still, he became entangled in a controversy with Lavoisier over the phlogiston theory, Priestley upholding it, the French chemist opposing it. 6 Priestley was also active in politics, supporting radical causes. He supported John Wilkes, of whom Hume thoroughly disapproved, and was an early... (shrink)

In this paper, I argue against John Beatty’s position in his paper “The Evolutionary Contingency Thesis” by counterexample. Beatty argues that there are no distinctly biological laws because the outcomes of the evolutionary processes are contingent. I argue that the heart of the Caspar–Klug theory of virus structure—that spherical virus capsids consist of 60T subunits (where T = k 2 + hk + h 2 and h and k are integers)—is a distinctly biological law even if the existence of spherical (...) viruses is evolutionarily contingent.

James Beattie was appointed professor of moral philosophy and logic at Marischal College, Aberdeen, Scotland at the age of twenty-five. Though more fond of poetry than philosophy, he became part of the Scottish 'Common Sense' school of philosophy that included Thomas Reid and George Campbell. In 1770 Beattie published the work for which he is best known, An Essay on Truth, an abrasive attack on 'modern scepticism' in general, and on David Hume in particular, subsequently and despite (...) class='Hi'>Beattie's attack, Scotland's most famous philosopher. The Essay was a great success, earning its author an honorary degree from Oxford and an audience with George III. Samuel Johnson declared in 1772 that 'We all love Beattie'. Hume, on the other hand, described the Essay as 'a horrible large lie in octavo', and dismissed its author as a 'bigotted silly Fellow'. Although Beattie is no match for Hume as a philosopher, the success of the Essay suggests that, unlike Hume, Beattie voices the characteristic assumptions, and anxieties, of his age. The first part of this selection—the first ever made from Beattie's prose writings—includes several key chapters from the Essay on Truth, along with extracts from all of Beattie's other works on moral philosophy. The topics treated include memory, the existence of God, the nature of virtue, and slavery. The second part of the selection is devoted to Beattie's contributions to literary criticism and aesthetics. Beattie's studies of poetry, music, taste, and the sublime are vital to the understanding of the literary culture out of which developed the early Romanticism of Wordsworth and Coleridge. (shrink)

There are many reasons why scientific experts may mask disagreement and endorse a position publicly as “jointly accepted.” In this paper I consider the inner workings of a group of scientists charged with deciding not only a technically difficult issue, but also a matter of social and political importance: the maximum acceptable dose of radiation. I focus on how, in this real world situation, concerns with credibility, authority, and expertise shaped the process by which this group negotiated the competing virtues (...) of reaching consensus versus reporting accurately the nature and degree of disagreement among them.

How, according to Darwin, does chance variation affect evolutionary outcomes? In his 1866 book, On the Various Contrivances by which British and Foreign Orchids are Fertilised by Insects, Darwin developed an argument that played an important role in his overall case for evolution by natural selection, as articulated in later editions of the Origin. This argument also figured significantly in Darwin's reflections on the theological dimensions of evolution by natural selection.

We contend that many of the criticisms of the American Psychological Association’s current Ethics Code are based on faulty assumptions and insufficient information. While the APA Ethics Committee values commentary on perceived shortcomings of the current Ethics Code as an important aspect of the current revision process, O’Donohue’s article contains inaccuracies that should be addressed. We clarify the functioning of the Ethics Code and the APA adjudication system, including explaining changes made to adjudication in light of the Commission on Ethics (...) Processes. We also explain the transparent, open process the APA has already undertaken to create a revised Ethics Code that is visionary and transformational. (shrink)

Much if not most recent literature in philosophy of biology concerns the extent to which biological theories conform to what is known as the "received" philosophical view of scientific theories, a descendant of the logical-empiricist view of theories. But the received view currently faces a competitor--a very different view of theories known as the "semantic" view. It is argued here that the semantic view is more sensitive to the nature and limitations of evolutionary theory than is the received view. In (...) particular, the semantic view better accomodates the fact that evolutionary theory is bound to change as a result of the evolutionary process itself. This unusual feature of evolutionary theory provides a good reason for reconsidering the received view and paying close attention to the semantic view. (shrink)

Among the liveliest disputes in evolutionary biology today are disputes concerning the role of chance in evolution--more specifically, disputes concerning the relative evolutionary importance of natural selection vs. so-called "random drift". The following discussion is an attempt to sort out some of the broad issues involved in those disputes. In the first half of this paper, I try to explain the differences between evolution by natural selection and evolution by random drift. On some common construals of "natural selection", those two (...) modes of evolution are completely indistinguishable. Even on a proper construal of "natural selection", it is difficult to distinguish between the "improbable results of natural selection" and evolution by random drift. In the second half of this paper, I discuss the variety of positions taken by evolutionists with respect to the evolutionary importance of random drift vs. natural selection. I will then consider the variety of issues in question in terms of a conceptual distinction often used to describe the rise of probabilistic thinking in the sciences. I will argue, in particular, that what is going on here is not, as might appear at first sight, just another dispute about the desirability of "stochastic" vs. "deterministic" theories. Modern evolutionists do not argue so much about whether evolution is stochastic, but about how stochastic it is. (shrink)

This article aims to read feminist new materialisms (Barad), together with ‘postulated’ linguistic or cultural primacy of Queer Theory (Butler), to show how both are engaged in similar critical-ethical endeavours. The central argument is that the criticism of Barad and new materialisms misses Butler’s materialistic insights due to a narrow interpretation of Butler's alleged social-constructivist position. There is, therefore, a specific focus on where they both make similar ethical appeals. Moreover, the article relies on Adorno's negative dialectic to highlight an (...) interpretation of Barad and Butler as being part of the same dialectical movement, in which materialism and idealism fluctuate in their mutual criticisms, thus continuing the procession towards 'new knowledge' and emancipation, or freedom, through their motions back and forth.

The prevalence of optimality models in the literature of evolutionary biology is testimony to their popularity and importance. Evolutionary biologist R. C. Lewontin, whose criticisms of optimality models are considered here, reflects that "optimality arguments have become extremely popular in the last fifteen years, and at present represent the dominant mode of thought." Although optimality models have received little attention in the philosophical literature, these models are very interesting from a philosophical point of view. As will be argued, optimality models (...) are central to evolutionary thought, yet they are not readily accomodated by the traditional view of scientific theories. According to the traditional view, we would expect optimality models to employ general, empirical laws of nature, but they do not. Fortunately, the semantic view of scientific theories, a recent alternative to the traditional view, more readily accomodates optimality models. As we would expect on the semantic view, optimality models can be construed as specifications of ideal systems. These specifications may be used to describe empirical systems--that is, the specifications may have empirical instances. But the specifications are not empirical claims, much less general, empirical laws. Although philosophers have yet to discuss the general features and uses of optimality models, these topics have stimulated much recent discussion among evolutionary biologists. Their discussions raise a number of precautions concerning the proper use of optimality models. Moreover, many of their caveats can be interpreted as general reminders that 1) optimality models specify ideal systems whose empirical instantiations may be quite restricted, and that 2) optimality models should not be construed as general, empirical laws. As G. F. Oster and E. O. Wilson caution, "the prudent course is to regard optimality models as provisional guides to further empirical research and not necessarily as the key to deeper laws of nature." It seems, then, that the semantic view of theories is more sensitive to the nature and limitations of optimality models than is the more traditional view of theories. (shrink)

"Theoretical pluralism" obtains when there are good evidential reasons for accommodating multiple theories of the same domain. Issues of "relative significance" often arise in connection with the investigation of such domains. In this paper, I describe and give examples of theoretical pluralism and relative significance issues. Then I explain why theoretical pluralism so often obtains in biology--and why issues of relative significance arise--in terms of evolutionary contingencies and the paucity or lack of laws of biology. Finally, I turn from explanation (...) to justification, and raise questions about the purpose and value of concerns and disagreements about relative significance. (shrink)

Ernst Mayr''s distinction between ultimate and proximate causes is justly considered a major contribution to philosophy of biology. But how did Mayr come to this philosophical distinction, and what role did it play in his earlier scientific work? I address these issues by dividing Mayr''s work into three careers or phases: 1) Mayr the naturalist/researcher, 2) Mayr the representative of and spokesman for evolutionary biology and systematics, and more recently 3) Mayr the historian and philosopher of biology. If we want (...) to understand the role of the proximate/ultimate distinction in Mayr''s more recent career as a philosopher and historian, then it helps to consider hisearlier use of the distinction, in the course of his research, and in his promotion of the professions of evolutionary biology and systematics. I believe that this approach would also shed light on some other important philosophical positions that Mayr has defended, including the distinction between essentialism: and population thinking.

This is the first of a two-part essay on the history of debates concerning the creativity of natural selection, from Darwin through the evolutionary synthesis and up to the present. Here I focus on the mid-late nineteenth century to the early twentieth, with special emphasis on early Darwinism and its critics, the self-styled “mutationists.” The second part focuses on the evolutionary synthesis and some of its critics, especially the “neutralists” and “neo-mutationists.” Like Stephen Gould, I consider the creativity of natural (...) selection to be a key component of what has traditionally counted as “Darwinism.” I argue that the creativity of natural selection is best understood in terms of selection initiating evolutionary change, and selection being responsible for the presence of the variation it acts upon, for example by directing the course of variation. I consider the respects in which both of these claims sound non-Darwinian, even though they have long been understood by supporters and critics alike to be virtually constitutive of Darwinism.

The classical/balance controversy continued along these lines throughout the first half of the sixties. Then, at about the same time that the classical position lost its leading advocate, the balance position received striking new support from Harry Harris, and independently from Dobzhansky's former student Lewontin, and Lewontin's research partner, Jack Hubby.80 These developments served more to reorient the controversy than to end it — and the resulting “neoclassical”/balance controversy is different enough to be grist for another mill.Social policy considerations no (...) longer play a role in keeping the dispute alive. This particular respect in which the issues have changed is, as Diane Paul suggests in her contribution to this volume, as striking as any other.82 There is, however, little danger of our forgetting that this was once much more than just a narrowly technical controversy — the additional social policy issues were far too blatant.However, although blatant, they were by no means the only, or even the most important, issues. In choosing to concentrate on the social policy considerations, I do not mean to suggest that the empirical issues were irrelevant, or simple and straightforward, or otherwise uninteresting. That is by no means the case. What I have tried to show is that there was much more to the classical/balance stalemate than just the empirical underdetermination of the theoretical issues, and that the empirical issues cannot be treated adequately without taking into account the social policy considerations that were involved. Dobzhansky and Muller both appealed to the dangers of misguided social policy that might have resulted from prematurely resolving their controversy in the other's favor. They called for high empirical standards on those grounds, more than once seeking to forestall the resolution of their dispute in this way. (shrink)
