The question of the morality of abortion has long been the subject of intense, sometimes acrimonious debate. Even people within the same religious or philosophical tradition often disagree on the issue. For example, there are Christians who are “pro- choice” and there are Christians who are “pro-life.” Both sides marshal biblical, theological, and philosophical arguments in support of their positions. The substance of the abortion debate seems to reduce to one tricky question: when does personhood begin? Christian experts in various (...) fields, such as theology, biblical studies, ethics, and philosophy, have protracted disagreements over this question. In this article we will apply insights from the current literature on epistemic peer disagreement to the abortion issue. We will assume that there is only one correct answer to the abortion question. However, after making a crucial distinction between rationality as understood by internalists versus externalists, we will argue that there is more than one rational answer to the abortion question, since there is more than one rational way to weight evidence. We will conclude that, in a case of disagreement between two Christians who are epistemic peers with regards to the morality of abortion, both parties can be rational in adhering to their respective positions, but that this does not entail or even support ethical relativism.

We are sceptical of concerns over the opacity of algorithmic decision tools. While transparency and explainability are certainly important desiderata in algorithmic governance, we worry that automated decision-making is being held to an unrealistically high standard, possibly owing to an unrealistically high estimate of the degree of transparency attainable from human decision-makers. In this paper, we review evidence demonstrating that much human decision-making is fraught with transparency problems, show in what respects AI fares little worse or better and argue that (...) at least some regulatory proposals for explainable AI could end up setting the bar higher than is necessary or indeed helpful. The demands of practical reason require the justification of action to be pitched at the level of practical reason. Decision tools that support or supplant practical reasoning should not be expected to aim higher than this. We cast this desideratum in terms of Daniel Dennett’s theory of the “intentional stance” and argue that since the justification of action for human purposes takes the form of intentional stance explanation, the justification of algorithmic decisions should take the same form. In practice, this means that the sorts of explanations for algorithmic decisions that are analogous to intentional stance explanations should be preferred over ones that aim at the architectural innards of a decision tool.

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)

The purpose of this book is to give a coherent account of the different perspectives on science and technology that are normally studied under various disciplinary heads such as philosophy of science, sociology of science and science policy. It is intended for students embarking on courses in these subjects and assumes no special knowledge of any science. It is written in a direct and simple style, and technical language is introduced very sparingly. As various perspectives are sketched out in this (...) book, the reader moves towards a consistent conception of contemporary science as a rapidly changing social institution that has already grown out of its traditional forms and plays a central role in society at large. It will appeal to students in a wide range of scientific disciplines and complement well Professor Ziman's earlier books. (shrink)

Nowadays, science is treated an instrument of policy, serving the material interests of government and commerce. Traditionally, however, it also has important non-instrumental social functions, such as the creation of critical scenarios and world pictures, the stimulation of rational attitudes, and the production of enlightened practitioners and independent experts. The transition from academic to ‘post-academic’ science threatens the performance of these functions, which are inconsistent with strictly instrumental modes of knowledge production. In particular, expert objectivity is negated by entanglement with (...) political and commercial interests. We cannot go back to the old academic model for science, but need to consider how to maintain its vital non-instrumental roles. (shrink)

I draw parallels and contrasts between dual-system and modular approaches to cognition, the latter standing to inherit the same problems De Neys identifies regarding the former. Despite these two literatures rarely coming into contact, I provide one example of how he might gain theoretical leverage on the details of his “non-exclusivity” claim by paying closer attention to the modularity debate.

Muy distinto a otros libros de carácter similar, cuidadosamente razonado, pero sin realizar un análisis técnico de la naturaleza y significado del conocimiento científico, ¿Qué es la ciencia? abre el camino a la reconciliación en la llamada “guerra de las ciencias”. A través de la descripción de cómo los científicos abordan realmente la investigación y transmiten sus resultados, muestra que la filosofía, la psicología y la sociología de la ciencia están inextricablemente relacionadas, y que el “realismo” y el “relativismo” son (...) sólo dos caras de la misma moneda. Estudia, además, cómo, para bien y para mal, la nueva cultura de la investigación “postacadémica”, basada en el trabajo en equipo y la responsabilidad, está cambiando las características filosóficas, supuestamente eternas, de la ciencia.

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.

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)

John Dewey's Experience and Nature has been considered the fullest expression of his mature philosophy since its eagerly awaited publication in 1925. Irwin Edman wrote at that time that "with monumental care, detail and completeness, Professor Dewey has in this volume revealed the metaphysical heart that beats its unvarying alert tempo through all his writings, whatever their explicit themes." In his introduction to this volume, Sidney Hook points out that "Dewey's Experience and Nature is both the most suggestive and (...) most difficult of his writings." The meticulously edited text published here as the first volume in the series The Later Works of John Dewey, 1925-1953 spans that entire period in Dewey's thought by including two important and previously unpublished documents from the book's history: Dewey's unfinished new introduction written between 1947 and 1949, edited by the late Joseph Ratner, and Dewey's unedited final draft of that introduction written the year before his death. In the intervening years Dewey realized the impossibility of making his use of the word 'experience' understood. He wrote in his 1951 draft for a new introduction: "Were I to write (or rewrite) Experience and Nature today I would entitle the book Culture and Nature and the treatment of specific subject-matters would be correspondingly modified. I would abandon the term 'experience' because of my growing realization that the historical obstacles which prevented understanding of my use of 'experience' are, for all practical purposes, insurmountable. I would substitute the term 'culture' because with its meanings as now firmly established it can fully and freely carry my philosophy of experience.". (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)

This book tells for the first time the long and complex story of the involvement of Locke's suggestion that God could add to matter the power of thought in his Essay Concerning Human Understanding in the growth of French materialism. There is a discussion of the 'affaire de Prades', in which Locke's name was linked with a censored thesis at the Faculty of Theology in Paris. The similarities and differences between English "thinking matter" and the French "matiere pensante" of the (...) philosophes are also discussed. (shrink)

This paper refutes two important and influential views in one fell stroke. The first is G.E. Moore’s view that assertions of the form ‘Q but I don’t believe that Q’ are inherently “absurd.” The second is Gareth Evans’s view that justification to assert Q entails justification to assert that you believe Q. Both views run aground the possibility of being justified in accepting eliminativism about belief. A corollary is that a principle recently defended by John Williams is also false, (...) namely, that justification to believe Q entails justification to believe that you believe Q. (shrink)

Late in his life, Hans-Georg Gadamer was asked to explain what the universal aspect of hermeneutics consisted in, and he replied, enigmatically, “in the _verbum interius_.” Gadamer devoted a pivotal section of his magnum opus, _Truth and Method_, to this Augustinian concept, and subsequently pointed to it as a kind of passkey to his thought. It remains, however, both in its origins and its interpretations, a mysterious concept. From out of its layered history, it remains a provocation to thought, expressing (...) something about the relation of language and understanding that has yet to be fully worked out. The scholastic idea of a word that is fully formed in the mind but not articulated served Augustine as an analogy for the procession of the Trinity, and served Thomas Aquinas as an analogy for the procession between divine ideas and human thought. Gadamer turned the analogy on its head by using the verbum interius to explain the obscure relation between language and human understanding. His learned interpretation of the idea of the inner word through Neoplatonism, Lutheranism, idealism, and historicism may seem nearly as complex as the medieval source texts he consulted and construed in his exegesis, but the profoundity of his insights are unquestioned. In unpacking Gadamer's interpretive feat, John Arthos provides an overview of the philosophy of the logos out of which the _verbum interius_ emerged. He summarizes the development of the _verbum _in ancient and medieval doctrine, traces its path through German thought, and explains its relevance to modern hermeneutic theory. His work unfolds in two parts, as an expansive intellectual history and as a close analysis and commentary on source texts on the inner word, from Augustine to Gadamer. As such, this book serves as an indispensable guide and reference for hermeneutics and the intellectual traditions out of which it arose, as well as an original theoretical statement in its own right. “Consummately researched, lucidly written, and persuasively argued throughout, __The Inner Word_ _succeeds brilliantly in bringing to light this neglected but pivotal matter in Gadamer’s work. Arthos is learned in the best ‘humanist’ way, for he succeeds in creating something new of his own that will speak eloquently to all of us.” —_Walter Jost, University of Virginia_ “Gadamer suggests that the Christian idea of incarnation is a key to his hermeneutics, but does not explain his position in a detailed or systematic manner. Arthos brings his considerable knowledge of hermeneutics and rhetoric to bear on Gadamer's insight, recounting the rich intellectual history to which Gadamer gestures, and providing an extended and detailed exegesis of this pivotal point in the third part of _Truth and Method_. Gadamer's account of 'linguisticality,' Arthos explains, can best be understood through his use of a complex metaphor—the ‘inner word.’ Arthos matches his erudition with clear and clean prose, and his account exemplifies, rather than just describes, Gadamer's hermeneutical philosophy. Any scholar interested in Gadamer's philosophy should have this book on his or her shelf.” —_Francis J. Mootz III, William S. Boyd Professor of Law, William S. Boyd School of Law_ “Arthos's strength lies for me in his careful reading of the sources. He effectively commands the literature on the subject. This work shows in a sophisticated way the legacy of trinitarian theology for philosophical hermeneutics. The very complex task of illuminating the phenomenon of the _verbum interius _and indicating its centrality for philosophical hermeneutics is accomplished by John Arthos with great sensitivity to the subject matter.” —_Andrzej Wiercinski, The International Institute for Hermeneutics_.

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.

This is an examination of the dialectical structure of deep disagreements about matters not open to empirical check. A dramatic case in point is the Law of Non-Contradiction . Dialetheists are notoriously of the view that, in some few cases, LNC has a true negation. The traditional position on LNC is that it is non-negotiable. The standard reason for thinking it non-negotiable is, being a first principle, there is nothing to negotiate. One of my purposes is to show that the (...) first-principle defence of LNC is inadequate. A second purpose is to argue that it flows from this inadequacy that LNC stands or falls on economic considerations, much in the spirit of Quine's pragmatism about logic generally. This is a tactical victory for dialetheists. It gives them room to make the case against LNC on cost-benefit grounds. As things presently stand, no such case can be considered decisive. But, given that costs and benefits shift with changing circumstances, it is possible that a winning case for the dialetheist may present itself in the future. Notwithstanding the rivalry between consistentists and dialetheists, they share a common opponent. This is trivialism, the doctrine that everything whatever is true. It is an ironic alliance, in as much as the dialetheist's case against the consistentist can be adapted to a defence of trivialism. How damaging this turns out to be depends on the adequacy of the reasons for the dialetheist's rejection of trivialism. My further purpose is to show that the damage is slighter than dialetheists commonly believe. (shrink)

It is important for our purposes to notice that in this first reduction of Theætetus' definition of knowledge as perception, Plato has introduced the distinction between sense object and physical object, for he has specifically said, "when the same wind is blowing, one of us feels chilly, the other does not." In using this example. Plato has, as Cornford observes, raised the question of how the several sense objects are related to the single physical object. This question is one of (...) the two major questions with which this paper will deal, since it is, as I have remarked, the more important question concerning the ontological status of sense-data. Cornford feels that Protagoras probably held that the physical object is both hot and cold, different observers perceiving different aspects of the same object. That is, Cornford suggests that Protagoras' own answer to this question of the relation between sense-data and physical objects is one of complete identification in every case. We will see that this theory is similar in many ways to the one worked out by Plato in the Theætetus, but the distinction between the physical object and the sense object, between the wind which feels hot and cold to different people, makes certain characteristic differences between Plato's and Protagoras' theory. Before going on to examine these differences, it is necessary to follow the further development of Plato's general theory of perception. (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 volume contains a collection of papers presented at the International Symposium, which took place in Hvar, Croatia, in 2006. In recent years there has been an upsurge of interest in the study of Plato, Platonism and Neoplatonism. Taking the position that it is of vital importance to establish an ongoing dialogue among scientists, artists, academics, theologians and philosophers concerning pressing issues of common interest to humankind, this collection of papers endeavours to bridge the gap between contemporary research in Platonist (...) philosophy and other fields where insights gained from the study of Plato and Platonist philosophy can be of consequence and benefit.
