Catullus' use of nutrices for the Nereids' breasts in line 18 of Poem 64 is not perhaps the most important problem in the poem, but it is not without interest and may have significance beyond its narrow context. This ‘weird preciosity’ has been integrated into a wider reading by Francis Cairns, who interestingly drew attention to Artemidorus 2.37–8 where to dream of Aphrodite emerging from the sea and naked as far as the ζώνη is a good omen for sea-travellers because (...) her breasts are τροΦιμώτατοι. So too, to dream of Nereids and Amphitrite is also a good omen. Cairns linked this passage to the persistent connections of Aphrodite and the Nereids with marriage, concluding that the Argonauts are presented with a very good omen as they set out and as the prospective bride and groom, Peleus and Thetis, meet. Cairns naturally finds support here for what we might call the ‘positive’ view of Catullus' heroic age, a view now apparently in the ascendant after the doubts created by John Bramble's well-known paper. Problems remain of course – Catullus 64 is not a dream – and the purpose of the present note is to keep debate alive by calling attention to a rather different set of considerations which complicate, rather than undermine, Cairns' reading.

Several psychological experiments have suggested that concepts can influence perceived color (e.g., Delk and Fillenbaum in Am J Psychol 78(2):290–293, 1965, Hansen et al. in Nat Neurosci 9(11):1367–1368, 2006, Olkkonen et al. in J Vis 8(5):1–16, 2008). Observers tend to assign typical colors to objects even when the objects do not have those colors. Recently, these findings were used to argue that perceptual experience is cognitively penetrable (Macpherson 2012). This interpretation of the experiments has far-reaching consequences: it implies that the (...) way we think of objects determines how we see them, thus threatening the role of perception in justifying beliefs. In this paper, I show that the psychological findings can be accounted for without admitting cognitive penetrability. An underestimated but key feature of the experiments is that observers had to judge colors in borderline cases, in conditions of reduced acuity, or on the basis of color-concepts instead of matching. Such judgments are sensitive to the form of bias that Tversky and Kahneman (Science 185:1124–1131, 1974) have termed ‘anchoring’. Adopting a suggestion from Raffman (Philos Rev 103(1):41–74, 1994), I argue that the way subjects in the experiments think of the objects could affect their color judgments without altering their color experiences.

The danger of human operators devolving responsibility to machines and failing to detect cases where they fail has been recognised for many years by industrial psychologists and engineers studying the human operators of complex machines. We call it “the control problem”, understood as the tendency of the human within a human–machine control loop to become complacent, over-reliant or unduly diffident when faced with the outputs of a reliable autonomous system. While the control problem has been investigated for some time, up (...) to this point its manifestation in machine learning contexts has not received serious attention. This paper aims to fill that gap. We argue that, except in certain special circumstances, algorithmic decision tools should not be used in high-stakes or safety-critical decisions unless the systems concerned are significantly “better than human” in the relevant domain or subdomain of decision-making. More concretely, we recommend three strategies to address the control problem, the most promising of which involves a complementary coupling between highly proficient algorithmic tools and human agents working alongside one another. We also identify six key principles which all such human–machine systems should reflect in their design. These can serve as a framework both for assessing the viability of any such human–machine system as well as guiding the design and implementation of such systems generally. (shrink)

No mathematical background is necessary to appreciate this classic of probability theory, which remains unsurpassed in its clarity, readability, and sheer charm. Its author, British logician John Venn (1834-1923), popularized the famous Venn Diagrams that are commonly used in teaching elementary mathematics.

This paper considers the applicability of standard accounts of causation to living systems. In particular it examines critically the increasing tendency to equate causal explanation with the identification of a mechanism. A range of differences between living systems and paradigm mechanisms are identified and discussed. While in principle it might be possible to accommodate an account of mechanism to these features, the attempt to do so risks reducing the idea of a mechanism to vacuity. It is proposed that the solution (...) to this problem requires the development of a philosophical account of process adequate to apply to living systems. (shrink)

Fresnel's theory of light was (a) impressively predictively successful yet (b) was based on an "entity" (the elastic-solid ether) that we now "know" does not exist. Does this case "confute" scientific realism as Laudan suggested? Previous attempts (by Hardin and Rosenberg and by Kitcher) to defuse the episode's anti-realist impact. The strongest form of realism compatible with this case of theory-rejection is in fact structural realism. This view was developed by Poincare who also provided reasons to think that it is (...) the only realist view of theories that really makes sense. (shrink)

En este artículo se analizan las relaciones del conocimiento científico con las sociedades en las que se produce. Tras repasar sus diversas funciones en tipos distintos de sociedades, la discusión se centra en los fines de la ciencia en las sociedades democráticas pluralistas. Frente al cada vez mayor rol instrumental de la ciencia, por el que ha recibido los nombres de «ciencia postacadémica» o «tecnociencia», se defienden los roles no instrumentales tradicionales de la investigación académica clásica. Se argumenta que sólo (...) si la ciencia académica mantiene su autonomía y su integridad frente a intereses políticos o empresariales podrá ser de utilidad al público al ofrecerle conocimiento imparcial y fidedigno frente a los sesgos producidos por la naturaleza propia de la ciencia postacadémica.

John Woods' The Logic of Fiction, now thirty-five years old, is a ground-breaking event in the establishment of the semantics of fiction as a stand-alone research programme in the philosophies of language and logic. There is now a large literature about these matters, but Woods' book retains a striking freshness, and still serves as a convincing template of the treatment options for the field's key problems. The book now appears in a second edition with a new Foreword by Nicholas (...) Griffin and an extended bibliography covering the period 1969-2009. As Griffin notes in his Foreword, it is "surprising on looking back to discover how little was written on the semantics of fiction before John Woods' The Logic of Fiction was published in 1974. The surprise is the greater because Woods' book appeared after almost a quarter century of fierce philosophical debate about reference Fictional discourse, one would have thought, would be an important testing ground for philosophical theories of referential expressions and one, moreover, in which the standard theories would likely be tested to destruction. " " One of the great merits of Woods' book is that it takes seriously the wide-ranging demands that fiction imposes on logic and semantics, and does not try to force fiction into some pre-conceived logical mould. but thanks to Woods' pioneering efforts, we are much closer to one now than we were when he set out to write his book. His book was not the last word on the logic of fiction; it was much more important: it was nearly the first." NICHOLAS GRIFFIN is Canada Research Chair in Philosophy at McMaster University. Recent publications include Russell vs Meinong: The Legacy of "On Denoting," edited with Dale Jacquette. JOHN WOODS is Director of the Abductive Systems Group at the University of British Columbia and Charles S. Peirce Visiting Professor of Logic in the Group on Logic and Computational Science, King's College London. He has two forthcoming books on fiction - an edited volume, Fictions and Models: New Essays, and a research monograph, Sherlock's Member: New Perspectives on the Semantics of Fiction, both to appear in 2010.

In lieu of an abstract, here is a brief excerpt of the content:Hume Studies Volume 29, Number 1, April 2003, pp. 125-141 Dr. George Cheyne, Chevalier Ramsay, and Hume's Letter to a Physician JOHN P. WRIGHT The publication of a new intellectual biography of George Cheyne1 provides a "propitious" occasion for "a thoroughly skeptical review"2 of the question which has long exercised Hume scholars, whether Cheyne was the intended recipient of David Hume's fascinating pie-Treatise Letter to a Physician,3 the (...) letter which describes his own hypochondriacal physical and mental symptoms and gives an account of his early philosophical development.4 Hume's nineteenth-century biographer, John Hill Burton, argued that Hume was probably writing to Cheyne,5 while Ernest Mossner claimed to definitively refute that hypothesis in an article entitled "Hume's Epistle to Dr. Arbuthnot," published in 1944.6 Anita Guerrini's intellectual biography does not discuss Cheyne as a possible recipient of Hume's letter, but she does present a well-rounded picture of this interesting eighteenth-century physician from which we can judge his appropriateness as its addressee. In the following discussion I will make use of the biographical material found in this new biography of Cheyne, as well as other sources, to show that Mossner's arguments are less than definitive, and that it would be wrong to dismiss the possibility that the letter was sent to George Cheyne.7 This is a possibility that, for reasons that I will make clear, makes good biographical and philosophical sense. At the same time, it is important to keep a proper suspense of judgment as Burton did, for the evidence that the letter was either intended for or actually sent to Cheyne is not definitive. John P. Wright is Professor of Philosophy, Central Michigan University, Mt. Pleasant, MI 48859, USA. e-mail: [email protected] 126 John P. Wright Burton, who first published the autobiographical letter of the 22-yearold Hume in 1846, narrowed down the possible addressees of Hume's letter to either Cheyne or John Arbuthnot. He also pointed out that it is possible that the letter was never sent, and that the ten and a half page manuscript is only a neatly written draft, rather than a fair copy of an actual letter. Nevertheless, Burton thought he could identify the unnamed addressee on the basis of the internal evidence of the manuscript and the records of Scottish physicians practicing in England at the time. In the letter, Hume refers to the intended recipient as his "Countryman, a Scotchman [,]... a skilful Physician, a man of Letters, of Wit, of Good Sense, & of great Humanity."8 Further he writes that he is consulting him because he is a person "of great Learning beyond [his]... own Profession" who is acquainted with the "Motions of the Mind" he has described in his letter, and that "Fame pointed [him]... out as the properest person to resolve my Doubts..." about the cure of his disorder.9 Burton tells us that "the first name that suggested itself... was Arbuthnot, whose fine genius was just then flickering in the socket."10 (John Arbuthnot had been ill for some time, and died a year later.) But he then added that "a more full consideration showed to my satisfaction that it must have been destined for Dr. George Cheyne." His main reason for settling on Cheyne was that Cheyne's immensely popular The English Malady (1733) had recently been published, and that "there is a certain unison of tone between Hume's letter and this book." Burton quotes a portion of Cheyne's own long autobiographical account of his own disease in The English Malady. Cheyne's autobiography begins with the claim that "I passed my Youth in close study, and almost constant Application to the abstracted Sciences, (wherein my chief pleasure consisted) and consequently in great Temperance and a Sedentary Life"; it is followed by the reflection that any overindulgence in food or drink led to physical and psychological problems.11 He goes on to describe these in great detail for 39 pages, along with a history of his life. Burton also quotes a section of the book in which Cheyne describes how a studious and sedentary life causes the symptoms... (shrink)

I want to discuss a doctrine and a concept in theory of knowledge which has various manifestations from at least the seventeenth to the early twentieth century. The concept is that of direct or immediate cognition, the doctrine says that only what is like mind can be directly or immediately present to mind. This doctrine raises the question of how we can know things other than ourselves and our experiences: the concept of direct presence most usually had the consequence of (...) making our knowledge of the world indirect, uncertain, or impossible. The directly present must in some way inform us about the indirectly present. (shrink)

John Passmore was a renowned Australian empirical philosopher and historian of ideas. In this book, which was originally published in 1952, Passmore's intention was to disentangle certain main themes in Hume's philosophy and to show how they relate to Hume's main philosophic purpose. Rather than offering a detailed commentary, the text provides an account based on specificity and critical scholarship, seeking to complement the other more comprehensive works on Hume's philosophy that had become available around the same time. This (...) book will be of value to anyone with an interest in perspectives on Hume and Passmore's philosophical approach. (shrink)

Philosophy as a separate discipline is a rather new phenomenon. This presents problems for our understanding of what constitutes the history of philosophy. Past writers often approached their concerns from a multi-disciplinary perspective; thus to understand them we have to do more than answer a contemporary set of issues. To that end, I suggest we attend to Locke's advice on how to read a text. Following this advice may permit us to avoid several puzzles which result from misreading a text.

David Hume's A Treatise of Human Nature presents the most important account of skepticism in the history of modern philosophy. In this lucid and thorough introduction to the work, John P. Wright examines the development of Hume's ideas in the Treatise, their relation to eighteenth-century theories of the imagination and passions, and the reception they received when Hume published the Treatise. He explains Hume's arguments concerning the inability of reason to establish the basic beliefs which underlie science and morals, (...) as well as his arguments showing why we are nevertheless psychologically compelled to accept such beliefs. The book will be a valuable guide for those seeking to understand the nature of modern skepticism and its connection with the founding of the human sciences during the Enlightenment. (shrink)

Since its modern inception in the early 1970s, informal logic has placed a special emphasis on the analysis of fallacies and argumentative dialogue schemes. Concurrent developments in speech communication circles exhibit a like concentration on the dialectical character of argument.

In the newly discovered letter Hume answers Reid's charge that he held a theory of ideas derived from his predecessors and criticizes Reid's own theory of innate ideas. He defends his own theory that ideas are derived from impressions. I discuss Reid's own puzzlement that in the first _Enquiry_ Hume ascribes a natural belief in necessary connections to the vulgar without an idea--and its influence on subsequent readings of Hume as a 'regularity theorist.' I argue that it was the 'Common (...) Sense' school of philosophers following Reid, rather than Hume, who insisted that beliefs must be based on legitimate ideas. (shrink)

The conflict between Kant and the medical faculty was far more complex and substantial than is indicated in the section of his famous Conflict of the Faculties addressing this matter.

For scientific essentialists, the only logical possibilities of existence are the real (or metaphysical) ones, and such possibilities, they say, are relative to worlds. They are not a priori, and they cannot just be invented. Rather, they are discoverable only by the a posteriori methods of science. There are, however, many philosophers who think that real possibilities are knowable a priori, or that they can just be invented. Marc Lange [Lange 2004] thinks that they can be invented, and tries to (...) use his inventions to argue that the essentialist theory of counterfactual conditionals developed in Scientific Essentialism [Ellis 2001, hereafter SE ] is flawed.

The appeal of scientific realism is chiefly based on the – staggering – empirical success of the theories currently accepted in science. The realist exhibits some currently accepted scientific theory (the General Theory of Relativity, say), points to its astounding empirical success (with the gravitational redshift, the precession of Mercury’s perihelion, etc) and suggests that it would be monumentally implausible to suppose that the theory could score such empirical successes and yet not reflect, at least to some good approximation, the (...) underlying nature of reality. To hold that combination of beliefs would be, in Poincaré’s celebrated phrase (1905/1952, p. 150), “to attribute an inadmissible role to chance”. (shrink)

Animal rights and vegetarianism for ethical reasons are positions gaining in influence in contemporary American culture. Although I think that certain rights for animals are consistent with and even entailed by the Catholic understanding of morality, vegetarianism is not. There is a plausible argument for an omnivorous diet from a Rawlsian original position. It is in direct contradiction to the Rawlsian-influenced ethical vegetarianism espoused by Mark Rowlands. Vegetarianism is not the moral high ground: ethical vegetarianism is in fact contrary to (...) a position on animals that is fundamentally pro-life. (shrink)

This article describes methods and ideas that emerged from a continuing enquiry into ‘metadesign’ that led us to think about the role of ‘consciousness’ in teams, communities and the biosphere. In the West the notion of ‘consciousness’ has been shaped by humanism, industrialization and some strident forms of individualism. These have encouraged us to see it in strongly anthropocentric and solipsistic terms. The global economic system also reflects this individualistic ideology, given that ‘growth’, is driven by personal avarice on a (...) collective scale. On the other hand, capitalism encourages enterprises to scale-up when they become successful. Both tendencies reduce the consciousness of organizations and communities. The article illustrates this idea by describing a ‘quadratic’ model of team consciousness that was developed to enhance practical developments that support personal, interpersonal, transpersonal and environmentally situated modes of awareness.

The distinctive feature of Professor Purtill's interesting, though somewhat promissory, paper, is its willingness to have the tail of pragmatics wag the dog of semantics. I myself find the pre-emption unfortunate, though I should hasten to add that Professor Purtill and I share something of a common view about the problems that should be solved by a decent account of fictionality; and some of our own solutions happen in fact to coincide. We part company, however, in respect of the following (...) two theses.Thesis. Professor Purtill holds that the sentences literally constitutive of a piece of fiction are neither true nor false, that they do not make assertions, that they do not make assertions about what they would appear to be about. Such sentences in fact tell tales, and in such nonassertive uses, they are spared the burdens of all but the limits of semantic significance. That is, they are not true and they are not false.

Hayek's reputation has gone through a remarkable cycle. An eminent exponent of the Austrian theory of business cycles in the 1930s, he was worsted in the controversy over Keynes' _Treatise on Money_. Following this defeat, Hayek retreated into capital theory, an esoteric branch of economics in which few economists then took an active interest. He gave up economics altogether after the war and turned to psychology, political philosophy, philosophy of law and the history of ideas. However, in 1974 he won (...) the Nobel Prize and returned to mainstream economics as a leading critic of Keynesianism and an advocate of free banking as the answer to inflation. Today Hayek reigns supreme as the kind of moral philosopher and political economist that economics has not seen since Adam Smith. Also forthcoming in this series is _Paul A. Samuelson, 2nd Series_.

The God of the Biblical and patristic tradition, though perhaps incomplete, possesses properties including those that involve genidentity or C-connections with us. Thus God's existence is at least possible. Using a modified version of Parson's elaboration of Meinong's theory of objects, we find that God exists if we do. But we also find that much else exists if we do; rather too much for confident belief.

In this paper, I take up Habermas’s recent writing on Rawls in Inclusion of the Other and focus on an example that Habermas discusses there, the Catholic stance on abortion. He brings in this example to question how such views could be rationally negotiated, under Rawls’s views of political liberalism, prior to arriving at an overlapping consensus. Habermas argues that Rawls must affirm the truth of moral constructivism in order to resolve the question of which conceptions of the good make (...) a valid claim on us. Though I have criticisms of how both Rawls and Habermas cast the issue of abortion, I argue that through properly understanding the role of the political ideal of citizenship in Rawls’s conception of political liberalism, we can find resources to contend with the problem Habermas finds here. I defend the capacity of political constructivism to resolve this issue without affirming the truth of moral constructivism. (shrink)
