We provide a positive solution for Post’s Problem for ordinal register machines, and also prove that these machines and ordinal Turing machines compute precisely the same partial functions on ordinals. To do so, we construct ordinal register machine programs which compute the necessary functions. In addition, we show that any set of ordinals solving Post’s Problem must be unbounded in the writable ordinals.

An analysis of the sources of Wittgenstein’s picture theory — which include not only his moment of insight on reading a magazine story about the use of models in a traffic court, but also the work of Russell, Hertz, and Boltzmann — provides the basis for an exploration of Wittgenstein’s articulation of a pictorial conception of representation in his wartime notebooks and its crystallization in the Tractatus. A discussion of Wittgenstein’s later criticism of the picture theory and his notion (...) of a “philosophical picture” illustrates the fundamental reversal in his transition to his later conception of philosophy: instead of taking literal pictures as a guide to the nature of meaning, he came to regard philosophical theories as akin to expressing an aesthetic preference for a certain style of representation. Wittgenstein’s treatment of factual language in the picture theory is related to his Tractarian approach to logical form, and the role of the show/say distinction in his early conception of logic and language. Particular attention is given to the difficulties generated by the idea that the conditions for the possibility of a given domain of discourse cannot be described in language, but must be shown by the form of words in question.

Although death by neurologic criteria is legally recognized throughout the United States, state laws and clinical practice vary concerning three key issues: the medical standards used to determine death by neurologic criteria, management of family objections before determination of death by neurologic criteria, and management of religious objections to declaration of death by neurologic criteria. The American Academy of Neurology and other medical stakeholder organizations involved in the determination of death by neurologic criteria have undertaken concerted action to address variation (...) in clinical practice in order to ensure the integrity of brain death determination. To complement this effort, state policymakers must revise legislation on the use of neurologic criteria to declare death. We review the legal history and current laws regarding neurologic criteria to declare death and offer proposed revisions to the Uniform Determination of Death Act and the rationale for these recommendations.

This paper looks at what David Kaplan's work on indexicals can teach us about logic and the philosophy of logic, and also what Kaplan's logic (i.e. the Logic of Demonstratives) can teach us about indexicals. The lessons are i) that logical consequence is not necessary truth-preservation, ii) that that the linguistic doctrine of necessary truth (also called conventionalism about modality) fails, and iii) that there is a kind of barrier to entailment between non-context-sensitive and context-sensitive claims.

Many historians of the calculus deny significant continuity between infinitesimal calculus of the seventeenth century and twentieth century developments such as Robinson’s theory. Robinson’s hyperreals, while providing a consistent theory of infinitesimals, require the resources of modern logic; thus many commentators are comfortable denying a historical continuity. A notable exception is Robinson himself, whose identification with the Leibnizian tradition inspired Lakatos, Laugwitz, and others to consider the history of the infinitesimal in a more favorable light. Inspite of his Leibnizian sympathies, (...) Robinson regards Berkeley’s criticisms of the infinitesimal calculus as aptly demonstrating the inconsistency of reasoning with historical infinitesimal magnitudes. We argue that Robinson, among others, overestimates the force of Berkeley’s criticisms, by underestimating the mathematical and philosophical resources available to Leibniz. Leibniz’s infinitesimals are fictions, not logical fictions, as Ishiguro proposed, but rather pure fictions, like imaginaries, which are not eliminable by some syncategorematic paraphrase. We argue that Leibniz’s defense of infinitesimals is more firmly grounded than Berkeley’s criticism thereof. We show, moreover, that Leibniz’s system for differential calculus was free of logical fallacies. Our argument strengthens the conception of modern infinitesimals as a development of Leibniz’s strategy of relating inassignable to assignable quantities by means of his transcendental law of homogeneity.

The new wave of ‘foundation models’—general-purpose generative AI models, for production of text (e.g., ChatGPT) or images (e.g., MidJourney)—represent a dramatic advance in the state of the art for AI. But their use also introduces a range of new risks, which has prompted an ongoing conversation about possible regulatory mechanisms. Here we propose a specific principle that should be incorporated into legislation: that any organization developing a foundation model intended for public use must demonstrate a reliable detection mechanism for the (...) content it generates, as a condition of its public release. The detection mechanism should be made publicly available in a tool that allows users to query, for an arbitrary item of content, whether the item was generated (wholly or partly) by the model. In this paper, we argue that this requirement is technically feasible and would play an important role in reducing certain risks from new AI models in many domains. We also outline a number of options for the tool’s design, and summarize a number of points where further input from policymakers and researchers would be required. (shrink)

The question I shall attempt to address in what follows is an essentially historical one, namely: Why did analytic philosophy emerge first in Cambridge, in the hands of G. E. Moore and Bertrand Russell, and as a direct consequence of their revolutionary rejection of the philosophical tenets that form the basis of British Idealism? And the answer that I shall try to defend is: it didn't. That is to say, the ‘analytic’ doctrines and methods which Moore and Russell (...) embraced in the very last years of the nineteenth century were not revolutionary, did not emerge first in Cambridge, were the creation of neither Russell nor Moore and cannot be explained by appeal to facts concerning British Idealism. The adoption of the doctrines and methods which characterised the earliest manifestations of British analytic philosophy are to be explained neither by reference to anything specifically British, nor by appeal to anything unproblematically philosophical. Or so I shall argue. (shrink)

Sackur joins several other recent French authors in writing penetrating analyses of Russell’s and Wittgenstein’s work. Forms and Factsz is an explication of the Tractatus, conducted by means of a contrast between Russell’s work and Wittgenstein’s. Sackur examines the interplay between Russell’s and Wittgenstein ’s versions of logical atomism, particularly, as Sackur puts it, between Russell’s original thought on the one hand, which provides the material for Wittgenstein’s position in the Tractatus, and Wittgenstein’s critique and development on the other, which, he says, provides a unity to Russell’s position (p. 12). While recognizing the inXuence of Russell on Wittgenstein’s project, Sackur in the end sees Wittgenstein as undermining and ultimately rejecting Russell’s logicism. He does not just repeat old claims about Wittgenstein, Russell and logical form. His analysis is very subtle and, perhaps unusually for a work on Wittgenstein which defends Wittgenstein over Russell, Formes et faitsz displays a surprisingly detailed knowledge of Russell’s work, before, during and after the period in question, 1913–19. Anyone who is interested in Russell’s and Wittgenstein ’s work during this period, and in particular Wittgenstein’s criticisms of Russell, will beneWt greatly from this book. There are detailed, well informed discussions of important points of disagreement, particularly Russell and Whitehead ’s account of succession and the ancestor relation, Wittgenstein’s remarks on operators, in particular the Nz operator, various remarks about the theory of types, and Wittgenstein’s now well known criticism of Russell’s theory of judgment. The subtitle of the work, “Analysis and the theory of knowledge in logical atomism”, reXects the points where Sackur sees the greatest disagreement between Russell and Wittgenstein.

While both of these points have been made before,1 Sackur’s discussion is more thorough than previous studies and leads to some new interpretations of passages in the Tractatus. Sackur’s discussion of analysis is important to his argument. He is interested in a tension between what he sees as two aims of analysis in Wittgenstein’s work, one found in Tractatusz 3.2–3.3 and the other in Tractatusz 4.21–4.2211. He sees analysis in the Wrst group as revealing or elucidating the sense a proposition expresses, a sense understood and already there in the ordinary unanalyzed proposition, and analysis in the second group, driven by the theses of necessity and logical independence, as focusing on truth-functional analysis in terms of elementary propositions that consist of names referring to simple objects. He argues that these two aims don’t automatically go together and in fact appear to be at cross purposes. In the course of the Wrst chapter, the major distinction Sackur makes is between analysis...

John Danford claims that Hume's philosophy must be understood within the framework of the 'problem of reason'. The problem of reason', according to this account, concerns the general relationship between philosophy and reason, on the one hand, and experience and 'common life' on the other. Danford maintains that the nature and development of Hume's thought, considered as a response to this problem, falls, essentially, into two parts. First, we must consider Hume's Treatise and his first Enquiry (ie., his 'epistemological works' (...) [61-cp.9]). The heart of Hume's Treatise, Danford suggests, lies with the epistemology of Book I and, in particular, with the discussions of causation and the external world. Hume's primary concern in these passages, it is argued, was to refute and discredit the rationalistic, 'scientific philosophies of Descartes and, especially, Hobbes (24-5, 40-5, 59, 74-5, 84-5, 190). These thinkers, Danford maintains, had driven a 'wedge' between philosophy and experienceor 'common life' (24-5). By emphasizing the limits and weakness of h u m a n understanding Hume exposes the vulnerability of Hobbes's and Descartes's scientific ambitions and, in this way, he seeks to return philosophy to the secure and appropriate foundations of 'common life and everyday experience.....Shortly after Hume published the Treatise there was, Danford claims, a 'shift' in his thinking on these matters (28). This shift is represented most clearly in his later works: the Essays, the History, and the Dialogues (10, 33, 7, 88, 108). Danford firmly rejects the suggestion that these works represent a turning away from philosophy. On the contrary, it is these later works, taken together, which constitute Hume's most mature philosophy. Indeed, they are, Danford says, the 'flower ofHume's philosophic career' (10). The mature philosophy of Hume, it is argued, must be interpreted as 'Political philosophy". It is political philosophy in the sense that it attempts to investigate human life in its full diversity and complexity and, on this basis, it seeks to provide us with some general guide as to how we should live (10, 7, 88-9, 183-6). From the 'teachings' of the History and the Essays Danford draws some lessons that are 'valid for all times' (112 and 114). The inspirational message concerns, roughly, the merits of capitalism (see, e.g., p. 131: The increase in personal liberty, then, was and is directly connected to the growth of commerce...' and p.137:'. the central lesson of British history [is] the superiority of liberal commercial society ...).

Timothy Williamson offers a proof of the counterintuitive claim that, if an object exists, then it exists necessarily. David Wiggins argues that this result reveals the philosophical disadvantage of a first level (or ‘ticking over’) view of the very ‘exists’ and the advantage of the second level account offered by Frege and Russell. The author seeks to show how, using an idea of G. Evans but without the use of the resources of ‘free logic’, all occurrences of ‘exist’, (...) including its occurrence in true, negative existential, singular statements, can be accommodated to the Frege–Russell view and accorded the intuitively required modal status.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Time of the Magicians: Wittgenstein, Benjamin, Cassirer, Heidegger, and the Decade That Reinvented Philosophy by Wolfram EilenbergerDavid HermanTime of the Magicians: Wittgenstein, Benjamin, Cassirer, Heidegger, and the Decade That Reinvented Philosophy, by Wolfram Eilenberger, trans. Shaun Whiteside; 432 pp. New York: Penguin Press, 2020.Is it possible to write a deeply researched and technically precise contribution to the history of philosophy that reads like a gripping novel? Time of (...) the Magicians, originally published in German in 2018 as Zeit der Zauberer, convincingly demonstrates that this feat can indeed be accomplished. However, it may be achievable only by the rare expert who, like Wolfram Eilenberger, combines a thoroughgoing knowledge of the field, an unstinting commitment to recreating a public forum for philosophy, and a gift for the exposition—and dramatization—of philosophical debates, the broader circumstances in which they took place, and the motivations and aims of those who participated in them.The book, stylishly translated by Shaun Whiteside, begins by plunging us into the middle of things. Eilenberger provides snapshots of what his four focal thinkers were up to in 1929, before backtracking, in subsequent chapters, to cover key events in the decade that brought them to this point. Then, in the epilogue, he briefly sketches their post-1929 lives and careers. The book's readability is further enhanced by the way the text is broken up into short sections with eye-catching titles ("A Hut of One's Own," "Existential Health Check," "Self-Fashioning through Openness").The opening pages center on June 1929, when Ludwig Wittgenstein, having previously renounced his portion of his family's fortune and taught for several years at primary schools in rural Austria, undertook an oral defense of his doctoral thesis at the University of Cambridge at age forty. Wittgenstein's "thesis" just so happened to be Tractatus Logico-Philosophicus, the influential, sometimes gnomic book he had published in 1921; and at the conclusion of the defense, the candidate is rumored to have said to his examiners, Bertrand Russell and G. E. Moore, "Don't worry, I know you'll never understand it."In fact, as Eilenberger discusses in a later chapter, by 1929 Wittgenstein's own thinking was no longer where it had been when he wrote the Tractatus. The [End Page 492] philosopher's primary concern had shifted away from identifying the logical structure of meaningful propositions; instead, he had become interested in how meaning emerges from the way language is used in particular, concrete contexts. Apropos the evolving nature of Wittgenstein's ideas, one of the funniest parts of the book describes the philosopher's meetings with members of the Vienna Circle, a group that, in seeking to reorient philosophy around the natural sciences, had come to see the Tractatus as a touchstone for their work. During his first meeting with the group, in 1927, Wittgenstein, instead of talking shop, recited poems by Indian poet Rabindranath Tagore, standing with his back turned to the audience. Later discussions did involve philosophy, but eventually, as Eilenberger puts it, although the "Vienna Circle had hoped for something that coincided with their ideal of objective research," they "were instead left to grapple with an extremely idiosyncratic style of thinking that, in both execution and results, seemed directly contrary to it" (p. 274).Meanwhile, a few months prior to Wittgenstein's defense of a thesis that no longer reflected his real tendencies of mind, two of Eilenberger's other focal thinkers, Ernst Cassirer and Martin Heidegger, engaged in a much-anticipated public debate at the Grand Hôtel Belvédère in Davos, Switzerland. When he first mentions it, Eilenberger furnishes just enough detail to whet readers' curiosity about this epochal contest between the eminent neo-Kantian Cassirer, whose reputation for encyclopedic erudition had just been sealed by the publication of the final volume of his masterwork, The Philosophy of Symbolic Forms, and the considerably younger Heidegger, a one-time student of Edmund Husserl who had made a radical departure from Husserlian phenomenology in Being and Time.By the time readers return to the debate, some three hundred pages later, Eilenberger has provided a decade's worth of historical context, which casts a...

Frank Ramsey was the greatest of the remarkable generation of Cambridge philosophers and logicians which included G. E. Moore, Bertrand Russell, Ludwig Wittgenstein and Maynard Keynes. Before his tragically early death in 1930 at the age of twenty-six, he had done seminal work in mathematics and economics as well as in logic and philosophy. This volume, with a new and extensive introduction by D. H. Mellor, contains all Ramsey's previously published writings on philosophy and the foundations of mathematics. The (...) latter gives the definitive form and defence of the reduction of mathematics to logic undertaken in Russell and Whitehead's Principia Mathematica; the former includes the most profound and original studies of universals, truth, meaning, probability, knowledge, law and causation, all of which are still constantly referred to, and still essential reading for all serious students of these subjects.

Scholarship on borderline vagueness pinpoints Russell's 1923 essay titled “Vagueness” as the starting point for rigorous analysis. The importance of Russell's work over and above discussions of indeterminacy in antiquity and in the modern period is that Russell isolated borderline vagueness from indeterminacies that do not threaten classical logic. This paper argues that historical propriety concerning the analysis of borderline vagueness belongs to Peirce since he was the first to show that borderline vagueness is distinct from other (...) forms of indeterminacy (e.g., generality, unspecificity, and uninformativeness) and that the application of vague predicates to borderline cases involves an intrinsic uncertainty.

There has been a recent focused effort in philosophical scholarship to bridge the perceived divide between pragmatism and analytic philosophy. This divide, it has been suggested, is over philosophical doctrines, methods, and even aims. This is not to say there has not been fruitful—even if antagonistic—dialogue between these two philosophical traditions. Clearly there has been, e.g., Russell's famous (or infamous) disputes with James and Dewey. Clearly also, there has been direct philosophical influence from one tradition to the other, e.g., (...) Peirce and Dewey on Quine's naturalistic works. Nevertheless, all too often the seminal works of pragmatists, especially the classical "Big Three," have not been mined by analytic philosophers, e.g., Peirce's writings on vagueness or on reference. This neglect has been, I believe, to the detriment of analytic philosophy. I intend this paper to be one step in correcting this neglect by suggesting both that Peirce's take on (scientific) explanation is a corrective to the prevailing models of explanation and that these models supply (at least in part) fecund additions to Peirce's views. First I will lay out four contemporary models of... (shrink)

In lieu of an abstract, here is a brief excerpt of the content:A THEORY OF BASIC GOODS: STRUCTURE AND HIERARCHY* I. FTEN, PERHAPS ALWAYS, moral theory emerges from particular problems. Just how is obscure. The logic of discovery is elusive; and it is harder to explain how we have come to see matters rightly than to recognize that we do, in fact, see them rightly. What counts as a theory, moreover, calls for explication as much as does a theory's emergence. (...) When we have in mind a theory that shapes our social vision, there is a progression from a central set of propositions, keyed to a range of paradigm cases and seen as a logical structure, to a " way of thinking " widely enough embraced to have political significance, at least for a given oommunity. In this essay I want to explore some fundamental questions raised by Germain Grisez's theory of natural law ethics.1 These questions are chiefly conceptual. But neither they nor Grisez's theory should be seen in a vacuum. Rather, I would begin by suggesting that the importance of his work, its emergence in some Catholic circles, is linked with two specific moral and political problems. The first is abortion; the second is the superpowers' policy of nuclear deterrence. *I thank David Blake, Robert Gordh, Carroll Kearley, Gary Mar. Martin Woods, and Linda Zagzebski for their comments on an earlier version of this essay. 1 For the theory's fullest presentation, see Germain Grisez, The Way of the Lord Jesus, vol. one, Ohristian Moral Principles, with the help of Joseph M. Boyle, Jr., Basil Cole, O.P., John Finnis, John A. Geinzer, Robert G. Kennedy, Patrick Lee, William E. May, and Russell Shaw (Chicago: Franciscan Herald Press, 1983). Especially critical are chapters two through twelve. 221 JAMES G. HANINK As a point of chronology, Grisez's early study of rubortion was the context for one of the first formulations of his natural law ethics.2 But why should this have been so? And why should abortion so engage Catholic thinkers, some of whom had felt a distance from explicitly Catholic positions, that Grisez's work should become pivotal? Answers to such questions must be tentative, but they include the following considerations. In a brief period, no more than a decade, legal abortion in the West became entrenched social policy.8 It was a policy, too, supported by dominant intellectual forces. But the new policy, defended in terms of individual freedom and a right to privacy, struck many Catholicsand non-Catholics-as vicious and tragic. It was vicious in that it made expendable the weakest and most vulnerable human beings. Human rights somehow became restricted to the strong and self-sufficient. The policy was tragic in its denial of human community. We are not, however much radical individualism supposes, merely a collection of separate egos. l/Ve are, rather, a community tied to a past and pledged to a future, so pledged, in part, by the children we bear and nurture.4 For in hearing and nurturing children we carry on the love of parents who have done as much for us; and we carry ourselves into a future where we hope our own love will be thus extended. But abortion, and surely unrestricted abortion, betrays this community of trust. Still, a policy so vicious and tragic can make us look for a fresh moral vision. And, of course, to the extent that we have contributed to,a climate in which abortion could become entrenched -either by our failures to support women in need or 2 Germain Grisez, Abortion: The Myths, the Realities, and the Arguments (New York and Cleveland: Corpus Books, 1970). a A milepost, of course, was the United States Supreme Court decision, Roe v. Wade, in 1973.

Seemingly, every mental act has a content or subject-matter. When I think, imagine, or hear, there appears to be a content or subject-matter of my thinking, imagining, or hearing. Now, what the difference is between this kind of content and the content of nonmental containers or containings, is a question which has beguiled even those thinkers, such as Ryle in England and physicalists in America, who are disinclined to recognize the mental as a separate ontic domain. When the problem of (...) isolating the nature of mental content or subject-matter was revived in the 19th century, Franz Brentano followed the Scholastics in calling these contents "intentions." The editor of the present volume, while noting that the concept of "intentionality has played a very central role in such philosophical movements as phenomenology, existentialism, and neo-Scholasticism," brings out the fact that this concept also, in recent years, was taken up by "philosophers in the analytical tradition as a powerful conceptual tool...."

In this paper I argue for the Atlas-Kempson Thesis that sentences of the form The A is not B are not ambiguous but rather semantically general (Quine), non-specific (Zwicky and Sadock), or vague (G. Lakoff). This observation refutes the 1970 Davidson-Harman hypothesis that underlying structures, as full semantic representations, are logical forms. It undermines the conception of semantical presupposition, removes a support for the existence of truth-value gaps for presuppositional sentences (the remaining arguments for which are viciously circular), and lifts (...) the Russell-Strawson dispute of 1950–1964 from stalemate to a formulation in which a resolution is possible for the first time. Suggestions of Davidson, Montague, Stalnaker, Kaplan and H. P. Grice are shown to be inadequate semantic descriptions of negative, presuppositional sentences. I briefly discuss the radical Pragmatics view of my 1975 publications and suggest that it too fails to do justice to the linguistic data. I speculate that Semantic Representations should be given the form (more or less) of computer programs, describable in Dana Scott's mathematical semantics for programming languages. (shrink)

Meaning is made out of the world by our actions in certain situations. But there are so many different things we can do, few of which actually create meaning. Not only do we utter linguistic expressions, but we move, gesture, point; we plan our actions to satisfy particular goals, we form beliefs, presumptions and prejudices, as well as ascribe intentions to other actors. In this paper three ways of acting are singled out for their function in making meaning out of (...) the world: demonstrations, indications and experiments. The paper develops some Wittgensteinean themes, such as the priority of demonstration, the nature of pictorial representations and the relation between interpretation and calculation, in the terms and concepts of Situation Theory. It attempts to weave some important elements of Wittgenstein’s thought in with an account of situated meaning and interpretation, without embarking on any archeological adventure. The paper is intended as a contribution to the philosophical foundations of Situation Theory and a critical commentary to some of its published accounts. Although Situation Theory has been developed with a sharp awareness of its antecedents in Bertrand Russell’s work, as well as its immediate heritage of central aspects of David Kaplan’s account of demonstrative reference, to my knowledge its Wittgensteinean roots have not been traced. The account of demonstrations, indications and experiments advocated here shows not only that important philosophical concerns of Situation Theory have their precursors in Wittgenstein’s work, but also that some of his insights could profitably be absorbed into its new foundations for a theory of meaning.

For more than seven decades there has been a broad gap between how philosophy is conceived and practiced. Two ill-defined but well-recognized traditions have developed—the "analytic" and "Continental" schools of philosophy. The former traces its roots to philosophers like Frege, Russell, Moore, Wittgenstein, and the logical positivists. The latter has been heavily influenced by Nietzsche, Heidegger, Merleau-Ponty, Foucault, and Derrida, among others. The aim of this collection is to reconsider the often facile characterization of major thinkers as belonging to (...) either one or the other philosophical tradition. The contributors—philosophers from both sides of the divide working in different countries and contexts—all question the problematic conception that the two traditions are incommensurable. Each of their articles compares individual philosophers who have had a major influence on the analytic and Continental traditions with a view to clarifying their similarities and dissimilarities of approach. What this collection of thoughtful articles clearly demonstrates is that regardless of approach and precedents, analytic and Continental philosophers are all doing philosophy, and there are many important points of contact between them. The contributors are: Richard Rorty, whose thoughtful overview highlights the salient points in both traditions; Barry Allen ; Babette E. Babich ; David Cerbone ; Sharyn Clough ; Jonathan Kaplan ; Richard Matthews ; Carlos G. Prado ; Bjorn Torgrim Ramberg ; Mike Sandbothe ; Barry Stocker ; and Ed Witherspoon. (shrink)

It is often said that a person P knows the meaning of a sentence S if P knows S’ s truth-conditions, in the sense that given any possible world, P knows whether S is true in that world. This idea of sentence-meaning corresponds fairly closely to what Frege, Russell, Carnap, and other philosophers have had in mind in speaking of the senses, propositional contents, or “locutionary” meanings of sentences; and, not unnaturally, it has encouraged semanticists such as David (...) Lewis, Robert Stalnaker and Max Cresswell to suggest that sentence-meanings or propositions simply are functions from the set of possible worlds onto the truth-values. (shrink)

The philosophy of Hegel had been dominant, in a Neo-Hegelian decaying form, in Great Britain at the end of the last century. It was then challenged there by the neo-empiricisms of Bertrand Russell and G. E. Moore. Development in the United States was parallel, except that Neo-Hegelianism was knocked from its citadel by William James, Dewey, and to a much lesser extent by Peirce. Dewey retained some Hegelianism in his new naturalistic approach.

Have you ever thought about how self-consciousness (self-awareness) originated in the universe? Understanding consciousness is one of the toughest "nuts to crack." In recent years, scientists and philosophers have attempted to provide an answer to this mystery. The reason for this is simply because it cannot be confined to solely a materialistic interpretation of the world. Some scientific materialists have suggested that consciousness is merely an illusion in order to insulate their worldviews. Yet, consciousness is the most fundamental thing we (...) know, even more so than the external world since we require it to perceive or think about anything. Without it, reasoning would be impossible. Dr. Scott Ventureyra, in this ground-breaking book, explores the idea of the Christian God and Creation in order to tackle this most difficult question. He demonstrates that theology has something significant to offer in reflection of how consciousness originated in the universe. He also makes a modest claim that the Christian conception of God and Creation provide a plausible account for the origin of self-consciousness. He integrates philosophy, theology, and science in an innovative way to embark on this exploration. (shrink)

The central question of this conference is whether the media can contribute to high quality social dialogue. The prospects for resolving that question positively in the “sound and fury” depend on recovering the idea of truth. At present the news media are lurching along from one crisis to another with an empty centre. We need to articulate a believable concept of truth as communication's master principle. As the norm of healing is to medicine, justice to politics, critical thinking to education, (...) craftsmanship to engineering, and stewardship to business, so truth-telling is the news profession's occupational norm. Truth-telling is the ethical framework that fundamentally reorders the media's professional culture and enables them to enrich social dialogue rather than undermine it.Historically the mainstream press has defined itself in terms of an objectivist worldview. Centred on human rationality and armed with the scientific method, the facts in news have been said to mirror reality. The aim has been true and incontrovertible accounts of a domain separate from human consciousness. In Bertrand Russell's formula, “truth consists in some form of correspondence between belief and fact” . In the received view, truth is defined in elementary epistemological terms as accurate representation. News corresponds to context-free neutral algorithms, and ethics is equated with impartiality.The attacks on this misguided view of human knowledge had already originated in Giambattista Vico's fantasia and Wilhelm Dilthey's verstehen in the counter-Enlightenment of the 18th century. They have continued with hermeneutics, critical theory in the Frankfurt School, American pragmatism, Wittgenstein's linguistic philosophy, Gramsci, and in their own way, Lyotard's denial of master narratives and Derrida's sliding signifiers; until the anti-foundationalism of our own day indicates a crisis in correspondence views of truth. Institutional structures remain Enlightenment-driven, but in principle the tide has turned currently toward restricting objectivism to the territory of mathematics, physics, and the natural sciences. In reporting, objectivity has become increasingly controversial as the working press' professional standard, though it will remain entrenched in our ordinary practices of news production and dissemination until an alternative mission for the press is convincingly formulated.The demise of correspondence views of truth has created a predicament for the notion of truth altogether. However, instead of appealing to coherence versions or abandoning the concept, truth needs to be relocated in the moral sphere. Truth is a problem of axiology rather than epistemology. With the dominant scheme no longer tenable, truth should become the province of ethicists who can reconstruct it as the news media's contribution to social dialogue.When truth is articulated in terms of a moral framework, we can mold its richly textured meaning around the Hebrew emeth , the Greek aletheia . In Serbo-Croatian the true is justified as with plumbline in carpentry. In the powerful wheel imagery of the Buddhist tradition, truth is the immovable axle. The Truth and Reconciliation Commission in South Africa presumes that sufferings from apartheid can be healed through truthful testimony. In Ghandhi's “satyagrapha,” the power of truth through the human spirit eventually wins over force . Dietrich Bonhoeffer's Ethics contends correctly that a truthful account lays hold of the context, motives, and presuppositions involved .Telling the truth depends on the quality of discernment so that penultimates do not gain ultimacy. Truth means, in other words, to strike gold, to get at “the core, the essence, the nub, the heart of the matter” . For Henry David Thoreau – though addressing a different issue – when we are truthful, we attempt to “drive life into a corner and¼if it proves to be mean, why then to get the genuine meanness out of it and publish its meanness to the world; or if it were sublime, to know it by personal experience and be able to give a true account of the encounter” . For the former secretary general of the United Nations, Dag Hammarskjold, “the most dangerous of all moral dilemmas is when we are obliged to conceal truth in order to help the truth be victorious” . In the Talmud, the liar's punishment is that no one believes him.Augustine , professor of rhetoric at Milan and later Bishop of Hippo, illustrates a non-correspondence view of truth. His rhetorical theory is a major contribution to the philosophy of communication, contradicting the highly secular and linear view of the ancient Greeks. As with Aristotle, rhetoric entails reasoned judgement for Augustine; however, he “break[s] away from Graeco-Roman rhetoric, moving instead toward ¼rhetoric as aletheiac act” . Rhetoric for him is not knowledge-producing or opinion-producing but truth-producing . The Epistolae Doctrina Christiana scourges the value-neutral, technical language of “word merchants” without wisdom.Truth is not fundamentally a prescriptive statement. The aletheiac act in Augustine “tends to be more relational than propositional, a dialogically interpersonal, sacramentally charitable act rather than a statement¼taking into account and being motivated by [the cardinal virtues] faith, hope, and charity” . The truth for him does not merely make things clear, but motivates us to belief and action. In truthful communication for Augustine, “it is not enough to seek to move men's minds, merely for the sake of power; instead, the power to move is to be used to lead men to truth”. (shrink)

I have two aims in this paper. In §§2-4 I contend that Moore has two arguments (not one) for the view that that ‘good’ denotes a non-natural property not to be identified with the naturalistic properties of science and common sense (or, for that matter, the more exotic properties posited by metaphysicians and theologians). The first argument, the Barren Tautology Argument (or the BTA), is derived, via Sidgwick, from a long tradition of anti-naturalist polemic. But the second argument, the Open (...) Question Argument proper (or the OQA), seems to have been Moore’s own invention and was probably devised to deal with naturalistic theories, such as Russell’s, which are immune to the Barren Tautology Argument. The OQA is valid and not (as Frankena (1939) has alleged) question-begging. Moreover, if its premises were true, it would have disposed of the desire-to-desire theory. But as I explain in §5, from 1970 onwards, two key premises of the OQA were successively called into question, the one because philosophers came to believe in synthetic identities between properties and the other because it led to the Paradox of Analysis. By 1989 a philosopher like Lewis could put forward precisely the kind of theory that Moore professed to have refuted with a clean intellectual conscience. However, in §§6-8 I shall argue that all is not lost for the OQA. I first press an objection to the desire-to-desire theory derived from Kripke’s famous epistemic argument. On reflection this argument looks uncannily like the OQA. But the premise on which it relies is weaker than the one that betrayed Moore by leading to the Paradox of Analysis. This suggests three conclusions: 1) that the desire-to-desire theory is false; 2) that the OQA can be revived, albeit in a modified form; and 3) that the revived OQA poses a serious threat to what might be called semantic naturalism.

The model of memory as a store, from which records can be retrieved, is taken for granted by many contemporary researchers. On this view, memories are stored by memory traces, which represent the original event and provide a causal link between that episode and one's ability to remember it. I argue that this seemingly plausible model leads to an unacceptable conception of the relationship between mind and brain, and that a non‐representational, connectionist, model offers a promising alternative. I also offer (...) a new reading of Wittgenstein's paradoxical remarks about thought and brain processes: as a critique of the cognitivist thesis that information stored in the brain has a linguistic structure and a particular location. On this reading, Wittgenstein's criticism foreshadows some of the most promising contemporary work on connectionist models of neural functioning. (shrink)

Discussion of Alexander Bogdanov as a Marxist revisionist has largely centred on his philosophy of being and cognition and on Plekhanov’s and Lenin’s accusation that Bogdanov was an idealist renegade from Marxism. However, the real issue of revisionism at the time was not materialism but determinism: the question of whether socialism would appear by the working of the objective laws of nature or the subjective will of human beings. Bogdanov did indeed revise Marxism, but he did so in order to (...) defend it as a natural science. He conceived of society as a form of life subject to biological laws of nature: the need to assimilate energy from the environment and the need to adapt to the environment in the struggle to survive. He reinterpreted the key elements of scientific socialism – the idea that existence determines consciousness and the labour theory of value – in terms of this worldview. (shrink)

The paper maps out and responds to some of the main areas of disagreement over the nature of Wittgenstein’s philosophy: (1) Between defenders of a “two Wittgensteins” reading (which draws a sharp distinction between early and late Wittgenstein) and the opposing “one Wittgenstein” interpretation. (2) Among “two-Wittgensteins” interpreters as to when the later philosophy emerged, and over the central difference between early and late Wittgenstein. (3) Between those who hold that Wittgenstein opposes only past philosophy in order to do philosophy (...) better and those who hold that Wittgenstein aimed to bring an end to philosophy and teach us to get by without a replacement. It is shown that each of these debates depends on some deeply un-Wittgensteinian, and quite mistaken, assumptions. It is concluded that Wittgenstein’s most polished writing, most notably in Philosophical Investigations I §§ 1–425, is best understood as a kind of Pyrrhonism which aims to subvert philosophical theorizing, by means of a polyphonic dialogue. Because this delicate balance between philosophical questions and their dissolution is not achieved in most of his other published and unpublished writings, we should be very cautious when using the theories and methods we find in those other writings as a guide to reading the Philosophical Investigations.

Examining the significance of Kant's account of "rational faith," this study argues that he profoundly revises his account of the human will and the moral philosophy of it in his later religious writings.

The use of voluntary assisted dying as an end‐of‐life option has stimulated concerns and debates over the past decades. Although public attitudes towards voluntary assisted dying (including euthanasia and physician‐assisted suicide) are well researched, there has been relatively little study of the different reasons, normative reasoning and rhetorical strategies that people invoke in supporting or contesting voluntary assisted dying in everyday life. Using a mix of computational textual mining techniques, keyword study and qualitative thematic coding to analyse public submissions to (...) a parliamentary inquiry into voluntary assisted dying in Australia, this study critically examines the different reasons, normative reasoning and rhetorical strategies that people invoke in supporting or contesting voluntary assisted dying in everyday life. The analysis identified complex and potentially contradictory ethical principles being invoked on both sides of the debate. These findings deepen our understanding of the moral basis of public reasoning about end‐of‐life matters and will help to inform future discussions on policy and law reform. The findings underscore the importance of sound normative reasoning and the use of caution when interpreting opinion polls to inform policy. (shrink)

The "standard account" of Wittgenstein’s relations with the Vienna Circle is that the early Wittgenstein was a principal source and inspiration for the Circle’s positivistic and scientific philosophy, while the later Wittgenstein was deeply opposed to the logical empiricist project of articulating a "scientific conception of the world." However, this telegraphic summary is at best only half-true and at worst deeply misleading. For it prevents us appreciating the fluidity and protean character of their philosophical dialogue. In retrospectively attributing clear-cut positions (...) to Wittgenstein and his interlocutors, it is very easy to read back our current understanding of familiar distinctions into a time when those terms were used in a much more open-ended way. The paper aims to to provide a broader perspective on this debate, starting from the protagonists’ understanding of their respective positions. Too often, the programmatic statements about the nature of their work that are repeated in manifestoes, introductions, and elementary textbooks have occupied center stage in the subsequent secondary literature. Consequently, I focus on a detailed examination of a turning point in their relationship. That turning point is Wittgenstein's charge, in the summer of 1932, that a recently published paper of Carnap's, "Physicalistic Language as the Universal Language of Science", made such extensive and unacknowledged use of Wittgenstein's own ideas that Wittgenstein would, as he put it in a letter to Schlick, "soon be in a situation where my own work shall be considered merely as a reheated version or plagiarism of Carnap’s." While the leading parties in this dispute shared a basic commitment to the primacy of physicalistic language, and the view that all significant languages are translatable, there was a remarkable lack of mutual understanding between them, and deep disagreement about the nature of the doctrines they disputed. Three quarters of a century later, we are so much more conscious of the differences that separated them than the points on which they agreed that it takes an effort of historical reconstruction to appreciate why Wittgenstein once feared that his own work would be regarded as a pale shadow of Carnap’s.

In this new introduction to a classic philosophical text, David Stern examines Wittgenstein's Philosophical Investigations. He gives particular attention to both the arguments of the Investigations and the way in which the work is written, and especially to the role of dialogue in the book. While he concentrates on helping the reader to arrive at his or her own interpretation of the primary text, he also provides guidance to the unusually wide range of existing interpretations, and to the reasons (...) why the Investigations have inspired such a diversity of readings. Following closely the text of the Investigations and meant to be read alongside it, this survey is accessible to readers with no previous background in philosophy. It is well-suited to university-level courses on Wittgenstein, but can also be read with profit by students in other disciplines. (shrink)

This book makes an important contribution to ongoing efforts in the fields of medical law and bioethics to answer the challenges posed by the limitations of the principle of respect for autonomy, especially as these pertain to human research ethics. The principle of respect for autonomy seems to have become firmly embedded in human research ethics since its inclusion in the 1947 Nuremberg Code, which was a response to atrocities committed by Nazi doctors. Nonetheless, there is an increasing awareness of (...) the limitations of the principle of respect for autonomy and the underlying conceptualisations of human autonomy. (shrink)

Human Dignity in Contemporary Ethics develops a holistic and relevant understanding of human dignity for ethics today. Whilst critics of the concept of human dignity call for its dismissal, and many of its defenders rehearse the same old arguments, this book offers an alternative set of methodological assumptions on which to base a revitalized and practical understanding of human dignity, which at the same time overcomes the challenges that the concept currently faces. The Component Dimensions of Human Dignity model enables (...) human dignity to serve both as a descriptive category that explains moral choices, and as a normative criterion that helps to evaluate moral behaviour. A consideration of two cases--violent crime and physician-assisted suicide--demonstrates how the model offers a way to avoid the pitfalls of both moralism and moral relativism, while still leaving space for relativity in ethics. By using an approach that should be acceptable to both religious and secular perspectives alike, this book offers a unique way out of the 'dignity talk' that currently plagues ethics. (shrink)
