Methods available for the axiomatization of arbitrary finite-valued logics can be applied to obtain sound and complete intelim rules for all truth-functional connectives of classical logic including the Sheffer stroke and Peirce’s arrow. The restriction to a single conclusion in standard systems of natural deduction requires the introduction of additional rules to make the resulting systems complete; these rules are nevertheless still simple and correspond straightforwardly to the classical absurdity rule. Omitting these rules results in systems for intuitionistic versions of (...) the connectives in question. (shrink)

The proof theory of many-valued systems has not been investigated to an extent comparable to the work done on axiomatizatbility of many-valued logics. Proof theory requires appropriate formalisms, such as sequent calculus, natural deduction, and tableaux for classical (and intuitionistic) logic. One particular method for systematically obtaining calculi for all finite-valued logics was invented independently by several researchers, with slight variations in design and presentation. The main aim of this report is to develop the proof theory of finite-valued first order (...) logics in a general way, and to present some of the more important results in this area. In Systems covered are the resolution calculus, sequent calculus, tableaux, and natural deduction. This report is actually a template, from which all results can be specialized to particular logics.

Logic has pride of place in mathematics and its 20th century offshoot, computer science. Modern symbolic logic was developed, in part, as a way to provide a formal framework for mathematics: Frege, Peano, Whitehead and Russell, as well as Hilbert developed systems of logic to formalize mathematics. These systems were meant to serve either as themselves foundational, or at least as formal analogs of mathematical reasoning amenable to mathematical study, e.g., in Hilbert’s consistency program. Similar efforts continue, but have been (...) expanded by the development of sophisticated methods to study the properties of such systems using proof and model theory. In parallel with this evolution of logical formalisms as tools for articulating mathematical theories (broadly speaking), much progress has been made in the quest for a mechanization of logical inference and the investigation of its theoretical limits, culminating recently in the development of new foundational frameworks for mathematics with sophisticated computer-assisted proof systems. In addition, logical formalisms developed by logicians in mathematical and philosophical contexts have proved immensely useful in describing theories and systems of interest to computer scientists, and to some degree, vice versa. Three examples of the influence of logic in computer science are automated reasoning, computer verification, and type systems for programming languages. (shrink)

Tested the 2-process theory of detection, search, and attention presented by the current authors in a series of experiments. The studies demonstrate the qualitative difference between 2 modes of information processing: automatic detection and controlled search; trace the course of the learning of automatic detection, of categories, and of automatic-attention responses; and show the dependence of automatic detection on attending responses and demonstrate how such responses interrupt controlled processing and interfere with the focusing of attention. The learning of categories is (...) shown to improve controlled search performance. A general framework for human information processing is proposed. The framework emphasizes the roles of automatic and controlled processing. The theory is compared to and contrasted with extant models of search and attention. (shrink)

The Curry-Howard isomorphism is a proof-theoretic result that establishes a connection between derivations in natural deduction and terms in typed lambda calculus. It is an important proof-theoretic result, but also underlies the development of type systems for programming languages. This fact suggests a potential importance of the result for a philosophy of code.

This paper explores two ways in which evaluations of an agent's character as virtuous or vicious are properly influenced by what the agent finds salient or attention-grabbing. First, we argue that ignoring salient needs reveals a greater deficit of benevolent motivation in the agent, and hence renders the agent more blameworthy. We use this fact to help explain our ordinary intuition that failing to give to famine relief is in some sense less bad than failing to help a child who (...) is drowning right before your eyes, in a way that's compatible with the contention that there's no principled reason to see the one life-saving act as any more or less choiceworthy than the other. Second, we argue that alleged ‘virtues of ignorance’ are better understood as ‘virtues of salience’. Rather than placing demands on what we believe, these virtues place demands on what we find salient. (shrink)

Having visited Ireland regularly during the 1930s, Ludwig Wittgenstein resigned his Cambridge philosophy professorship in 1947 and moved there, living in a fishing village on the Atlantic coast and hotels in Dublin and the Wicklow Mountains. Although Wittgenstein spent some time out of the country, Ireland was effectively his base for three very productive years during which he worked on what would become one of his key books, the posthumously published Philosophical Investigations. Wittgenstein in Ireland represents the first sustained account (...) of Wittgenstein's time in Ireland, placing it in its historical context. Wall pays a good deal of attention to the representation of the Irish landscape in which the Austrian philosopher found himself able to work; a large part of his writings were produced in the bleak landscapes of Ireland and Norway.

This article reviews current methods for evaluating models in the cognitive sciences, including theoretically based approaches, such as Bayes factors and minimum description length measures; simulation approaches, including model mimicry evaluations; and practical approaches, such as validation and generalization measures. This article argues that, although often useful in specific settings, most of these approaches are limited in their ability to give a general assessment of models. This article argues that hierarchical methods, generally, and hierarchical Bayesian methods, specifically, can provide a (...) more thorough evaluation of models in the cognitive sciences. This article presents two worked examples of hierarchical Bayesian analyses to demonstrate how the approach addresses key questions of descriptive adequacy, parameter interference, prediction, and generalization in principled and coherent ways.

The Intergovernmental Panel on Climate Change has developed a novel framework for assessing and communicating uncertainty in the findings published in their periodic assessment reports. But how should these uncertainty assessments inform decisions? We take a formal decision-making perspective to investigate how scientific input formulated in the IPCC’s novel framework might inform decisions in a principled way through a normative decision model.

ABSTRACT:Moral realism entails that there are metaphysically necessary moral principles of the form ‘all actions of nonmoral kind Z are morally good’; being discoverable a priori, these must be logically necessary. This article seeks to justify this apparently puzzling consequence. A sentence expresses a logically necessary proposition iff its negation entails a contradiction. The method of reflective equilibrium assumes that the simplest account of the apparently correct use of sentences of some type in paradigm examples is probably logically necessary. An (...) account is simple insofar as it uses few predicates designating properties easily recognizable in many different kinds of paradigm examples. I illustrate how reflective equilibrium uses these criteria to discover logically necessary nonmoral propositions such as ‘if S remembers doing X, S believes that he did X’ and ‘if it is scarlet, it is red’. I then illustrate how exactly the same procedures can lead us from paradigm examples of apparently true sentences asserting that actions of some kind are good to discovering moral principles. I advance the contingent hypothesis that most contemporary humans, although they initially disagree about moral issues, have derived from different paradigm examples the same concept of moral goodness, which will ensure that the use of reflective equilibrium will lead to eventual agreement about moral issues. That strongly suggests that the moral principles eventually reached by reflective equilibrium are logically necessary ones. (shrink)

Sociomaterial theories, including actor–network theory (ANT), materialist feminism and posthumanism, are sometimes argued to not be addressing or unable to address sufficiently the political and are therefore dismissed as irrelevant to educational research. Through an extended discussion of writers across the social sciences, this article seeks to counter such a view. Drawing specifically on the work of Latour on the nature of critique and on examples of political analysis from writers such as Barad, Bennett, Braidotti, Marres and Whatmore, we suggest (...) that sociomaterialist approaches to the more-than-human open up extended understandings and productive alternative practices of politics. While recognising that this is a work in progress and not without difficulties and challenges, we argue that there is much to be gained for educational researchers from engaging with such approaches.

When the modern artist is seen as moving about in a nebulous area between two opposing worlds, that of life or immediate experience and that of art or established truth, I think it is appropriate to discuss this activity in terms of metaphor. Indeed the present concern for metaphor in the academic and artistic communities is but one of many reflections of our sense that life is a process of the gradual attainment of knowledge through experience, whether sensuous or intellectual. (...) Like our artists, we strive to create a picture of our world, yet that picture is never complete; for we continually pass on to new experiences and new images of reality. Not only do we grow and change but our world seems to change with us. Although the truths revealed through our art are founded in our experience, they seem more permanent and public than the acts of discovery leading to them. A principle once established and integrated with a body of other established truths enters into recorded history perhaps to be revered, disputed, or reinterpreted, but nevertheless to remain. The individual experience or discovery, however, passes; with the individual, only the sense of the continuing search yields personal identity. In a changing world, metaphor renders the truth of experience as the truth of knowledge, for it is the means of passing from individual immediacy to an established public world; the new must be linked to the old, and the experience of any individual must be connected with that of his society. Excluding the possibility of the creation of entirely new worlds and the resultant transformation of all personal identities, acts of genius or dramatic breakthroughs in fields of study can affect our present world order only if they are joined to it by means of a powerful metaphor. Indeed establishing the metaphoric bridge itself may be considered the act of genius, and the entry into new areas of knowledge is its consequence.

RICHARD SHEDENHELM responds to Robert Campbell's essay, "Ayn Rand and the Cognitive Revolution in Psychology" . He identifies the most likely source of the crow-counting experiment cited at the beginning of chapter seven of Ayn Rand's Introduction to Objectivist Epistemology. He finds that the crow study was not at all an experiment, but instead an anecdotal account dating from the eighteenth-century French writer of animal behavior, Charles-Georges Leroy.

Nietzsche announces his intentions to publish a “physiology of aesthetics”, namely a naturalistic explanation for how aesthetic judgements are grounded in the physiology of both the one experiencing the work, and the creator of it. But as well as the physiological reduction of aesthetic judgements, Nietzsche in many places across his oeuvre frames the apparatus of physiology, especially the prescriptive dimension of self-cultivation, in terms amenable to being treated as ‘aesthetic’. The first section will mount a (re-) defense of the (...) use of aestheticized language for discussing Nietzschean self-cultivation. The second section demonstrates an aesthetic evaluation of capacities that make possible the acquisition and removal of instinctual components, ultimately arguing for Nietzsche’s qualified indeterminism regarding the capacity for self-cultivation. The third section will assess the pres- ence of another aesthetic measure, this time in terms of envisaging one’s psycho-physiology by reference to an external spectacle. The final section discusses metaethical questions stemming from Nietzsche’s prescriptive language regarding the aestheticization of our physiology. (shrink)

In _Charles Peirce and Modern Science_, T.L. Short encourages us to read Peirce’s oeuvre in the spirit of philosophical experimentalism. The result is a rewarding and refreshing book that clarifies longstanding controversies and stakes out novel positions in the debates.

I argue that while much of what he states is correct, he errs in holding that induction is invalid in the short run of an individual’s (...) life. (shrink)

When making decisions, people naturally face uncertainty about the potential consequences of their actions due in part to limits in their capacity to represent, evaluate or deliberate. Nonetheless, they aim to make the best decisions possible. In Decision Theory with a Human Face, Richard Bradley develops new theories of agency and rational decision-making, offering guidance on how 'real' agents who are aware of their bounds should represent the uncertainty they face, how they should revise their opinions as a result (...) of experience and how they should make decisions when lacking full awareness of, or precise opinions on relevant contingencies. He engages with the strengths and flaws of Bayesian reasoning, and presents clear and comprehensive explorations of key issues in decision theory, from belief and desire to semantics and learning. His book draws on philosophy, economics, decision science and psychology, and will appeal to readers in all of these disciplines. (shrink)

In his essay “Painting Memories” , Michael Fried identifies memory as the privileged thematic that structures Charles Baudelaire’s Salon of 1846. But he then limits his investigation of this topic by focusing on the representation of “past” art, to the exclusion of the recollection of “past” experience. Fried thus isolates the theme of memory from the dialectic of life and art that characterizes its performance for Baudelaire. Such selective analysis not only reverses Baudelaire’s priorities but deflects his pointed comments on (...) modernity and naiveté, which in turn inform the example of Edouard Manet, Fried’s exemplary modernist painter. One wonders whether too much of Baudelaire and Manet is lost to this view. Perhaps the predilections of contemporary criticism have sanctioned Fried’s approach. For today we hesitate to ground art in experience, preferring to conceive of representations as signs fully engendered by and engendering other signs. Baudelaire was of a different mind; he lived through the dawning of our own age, but also in the fading light of another. He was heir to a tradition that regarded the forms of art as powerfully motivated by the experience of internalized ideas and sensations; for him, a master artist’s “signs” would appear more symbolic than allegorical, more immediate than mediated or distanced. As we deny artistic signs motivation in extralinguistic “experience,” we aggravate that perennial problem of origins which Fried himself invokes. It might be reformulated in this manner: all painting depends on a lineage of antecedent painting; yet, to succeed, a new work must transcend its filial bondage, as it compounds the effect of the “original” in its own originality. Vexation follows from this issue of the artistic source. Since memories of past art make possible the very creation of art, the creative event cannot assume priority over memory. And the matter of primordial memory, like the matter of an absolutely original art, is aporia. Fried does not pursue this matter ; but the question necessarily implies that both representations and memories, in constituting the “past,” must always be distanced. Distanced not from the present, which they enter and likewise constitute, but from those “original” experiential moments they purport to present. Richard Schiff is associate professor of art at the University of North Carolina at Chapel Hill.

While different groups of viewers may have sought different values in Cézanne's art, the artist's manner of painting and personality both contributed to the ambiguity of his work. Until the last decade of his life he seldom exhibited, and even then his paintings seemed unfinished. He was generally regarded as an "incomplete" artist and often as a "primitive," one whose art was in some way simple or rudimentary, devoid of the refinements and complexities of his materialistic, industrialized society.1 He was (...) seen as an isolated man who lived apart from other painters and found human relationship and communication difficult. Yet for some symbolists it was this alienation and mystery which made Cézanne's art so attractive. As early as 1891, Fénéon found it appropriate to refer to "the Cézanne tradition," a designation which indicates the influence of the legendary account of the artist promulgated by Gauguin and his associates.2 Gauguin had painted landscapes with the reclusive artist during the summer of 1881, was impressed by his odd style, both personal and pictorial, and in a letter to Emile Schuffenecker of 14 January 1885 described Cézanne as embodying the mysticism of the Orient.3 Such a characterization held special meaning for those like Gauguin who had come more and more to search for an ultimate truth in the experience of the mystical, the transcendental, the intensely real. For the symbolist painter or writer, primitives lived in harmony with the real world; they had an intuitive, mythic understanding of their environment. Most modern Europeans, in contrast, viewed the world through false and short-sighted analytic reason and thus saw only immediate causes and effects, not eternal universal principles. They were Christians who could not see the truth of Buddhism; they were socially indoctrinated Parisians who could not see the purer structure of human society in provincial Brittany; they were refined painters of nature who could not see the expressive power of a flat area of color surrounded by a broad outline. For Gauguin and the symbolists, Cézanne, living in isolation in his seemingly unsophisticated native Provence, qualified as an enlightened contemporary, an inspiring force, a primitive artist. · 1. For Cézanne as "incomplete," see, e.g. Thadée Natanson, "Paul Cézanne." Revue blanche 9 , p. 496; and Gustave Geoffrey, "Paul Cézanne" , in La Vie artistique , p. 218.

The late nineteenth-century notion of the "primitive" artist was very broad. Included in the category of primitives were artists of the ancient Orient, artists of the earlier stages of development of various Western styles , provincial or uneducated European artists, and those of contemporary non-European societies. With regard to the negative evaluation of modern Western European society, see, e.g., Victor de Laprade, Le Sentiment de la nature chez les modernes, 2d ed. , pp. 483-88; and Albert Aurier, "Essai sur une nouvelle méthode de critique" , "Le Symbolisme en peinture: Paul Gauguin" , and "Les Isolés: Vincent van Gogh" , in Oeuvres posthumes , pp. 202, 216, 262-63.· 2.

ABSTRACTThe modern view of economic conspiracies stands in stark contrast to the view in the eighteenth century. Such classical economists as Adam Smith took conspiracy to be the natural result of our tendency to associate with one another. It manifested itself in collusion among both laborers and manufacturers to raise their income. By the mid-twentieth century, however, economists had come around to an entirely different view, according to which voluntary collaboration, especially in large groups, was unnatural and irrational, such that (...) the only way to sustain cartels and trade unions was via compulsory, tyrannical measures. The notion of rationality that underlies such a view—as seen in the parallel notion that it is irrational to vote—threatens the understanding of agency that is essential to democracy. (shrink)

In terminally ill individuals who would otherwise end their own lives, active voluntary euthanasia (AVE) can be seen as life-extending rather than life-shortening. Accordingly, AVE supports key pro-euthanasia arguments (appeals to autonomy and beneficence) and meets certain sanctity of life objections. This paper examines the extent to which a terminally ill individual’s wish to donate organs after death contributes to those life-extension arguments. It finds that, in a terminally ill individual who wishes to avoid experiencing life he considers to be (...) not worth living, and who also wishes to donate organs after death, AVE maximizes the likelihood that such donations will occur. The paper finds that the wish to donate organs strengthens the appeals to autonomy and beneficence, and fortifies the meeting of certain sanctity of life objections, achieved by life-extension arguments, and also generates appeals to justice that form novel life-extension arguments in favour of AVE in this context.

In the recent philosophical literature on inquiry, epistemologists point out that their subject has often begun at the point at which you already have your evidence and then focussed on identifying the beliefs for which that evidence provides justification. But we are not mere passive recipients of evidence. While some comes to us unbidden, we often actively collect it. This has long been recognised, but typically epistemologists have taken the norms that govern inquiry to be practical, not epistemic. The recent (...) literature challenges this assumption and uncovers a rich range of questions about the epistemic normativity of inquiry. In this paper, I approach these questions from the formal side of epistemology. Developing out of the philosophy of science, as it did, this branch of epistemology has long discussed inquiry. And, building on the insights of Janina Hosiasson (1931), David Blackwell (1951), and I. J. Good (1967), it has produced a reasonably well-developed framework in which to understand norms of inquiry, both epistemic and practical. In the first half of the paper, I will present the pragmatic versions of this framework due to Hosiasson, Blackwell, and Good, and the epistemic version due to Graham Oddie (1997); in the second half of the paper, I put this framework to work, turning to some of the questions from the recent debate about inquiry and asking how the framework can help us answer them. Questions will include: When should we initiate an inquiry, when should we continue it, when should we conclude it, and when should we reopen it? How should we understand Julia Staffel's distinction between transitional attitudes and terminal attitudes (Staffel 2021a,b)? How do epistemic norms of inquiry relate to epistemic norms of belief or credence, and can they conflict (Friedman 2020)? And how should we understand the epistemic error that occurs when someone is resistant to evidence (Simion 2023)? (shrink)

Drawing on a passage from Ramsey's Truth and Probability, we formulate a simple, plausible constraint on evaluating the accuracy of credences: the Calibration Test. We show that any additive, continuous accuracy measure that passes the Calibration Test will be strictly proper. Strictly proper accuracy measures are known to support the touchstone results of accuracy-first epistemology, for example vindications of probabilism and conditionalization. We show that our use of Calibration is an improvement on previous such appeals by showing how it answers (...) or sidesteps problems that have been raised for previous work in this area. (shrink)

Conscientious refusal involves decisions by healthcare workers, on grounds of their conscience, to refuse to provide legal, professionally permissible and safe health interventions to patients. Conscientious provision involves decisions by healthcare workers, also on grounds of conscience, to provide safe and beneficial healthcare to patients that is prohibited by law or policy. Some bioethicists believe that the moral issues governing both are identical, and that if one permits conscientious refusals, one should also permit conscientious provisions. This article argues that this (...) assumption of symmetry is incorrect. To demonstrate this, it does the following: first, it establishes why it matters that we understand the difference between them; second, it describes three recent cases of conscientious provision in Canadian healthcare to help characterize its nature and scope; third, it situates these cases in a socio-economically nuanced analysis of the role of the conscientious provider under conditions or privilege and oppression; finally, it applies insights from the cases and the intersectional analysis to common criticisms of conscientious refusal to reinforce the fundamental asymmetries between conscientious refusal and conscientious provision.

Effective altruism sounds so innocuous—who could possibly be opposed to doing good more effectively? Yet it has inspired significant backlash in recent years. This paper addresses some common misconceptions and argues that the core “beneficentric” ideas of effective altruism are both excellent and widely neglected. Reasonable people may disagree on details of implementation, but all should share the basic goals or values underlying effective altruism.
