This paper concerns the question of how to draw inferences common sensically from uncertain knowledge. Since the early work of Shore and Johnson (1980), Paris and Vencovská (1990), and Csiszár (1989), it has been known that the Maximum Entropy Inference Process is the only inference process which obeys certain common sense principles of uncertain reasoning. In this paper we consider the present status of this result and argue that within the rather narrow context in which we work this complete (...) and consistent mode of uncertain reasoning is actually characterised by the observance of just a single common sense principle (or slogan). (shrink)

We investigate uncertain reasoning with quantified sentences of the predicate calculus treated as the limiting case of maximum entropy inference applied to finite domains.

We consider two formalizations of the notion of irrelevance as a rationality principle within the framework of (Carnapian) Inductive Logic: Johnson's Sufficientness Principle, JSP, which is classically important because it leads to Carnap's influential Continuum of Inductive Methods and the recently proposed Weak Irrelevance Principle, WIP. We give a complete characterization of the language invariant probability functions satisfying WIP which generalizes the Nix-Paris Continuum. We argue that the derivation of two very disparate families of inductive methods from alternative perceptions (...) of 'irrelevance' is an indication that this notion is imperfectly understood at present.

The logical consequence relations η▹η provide a very attractive way of inferring new facts from inconsistent knowledge bases without compromising standards of credibility. In this short note we provide proof theories and completeness theorems for these consequence relations which may have some applicability in small examples.

This paper corrects three widely held misunderstandings about Maxent when used in common sense reasoning: That it is language dependent; That it produces objective facts; That it subsumes, and so is at least as untenable as, the paradox-ridden Principle of Insufficient Reason.

Can one extend crisp Peano arithmetic PA by a possibly many-valued predicate Tr(x) saying “xis true” and satisfying the “dequotation schema”for all sentences φ? This problem is investigated in the frame of Łukasiewicz infinitely valued logic.

Can one extend crisp Peano arithmetic PA by a possibly many-valued predicate Tr(x) saying "x is true" and satisfying the "dequotation schema" $\varphi \equiv \text{Tr}(\bar{\varphi})$ for all sentences φ? This problem is investigated in the frame of Lukasiewicz infinitely valued logic.

Rational Pavelka logic extends Lukasiewicz infinitely valued logic by adding truth constants r̄ for rationals in [0, 1]. We show that this is a conservative extension. We note that this shows that provability degree can be defined in Lukasiewicz logic. We also give a counterexample to a soundness theorem of Belluce and Chang published in 1963.

A necessary and sufficient condition in terms of a de Finetti style representation is given for a probability function in Polyadic Inductive Logic to satisfy being part of a Language Invariant family satisfying Spectrum Exchangeability. This theorem is then considered in relation to the unary Carnap and Nix–Paris Continua.

We argue in favour of identifying one aspect of rational choice with the tendency to conform to the choice you expect another like-minded, but non-communicating, agent to make and study this idea in the very basic case where the choice is from a non-empty subset K of 2 A and no further structure or knowledge of A is assumed.

We give a brief account of some de Finetti style representation theorems for probability functions satisfying Spectrum Exchangeability in Polyadic Inductive Logic, together with applications to Non-splitting, Language Invariance, extensions with Equality and Instantial Relevance.

This paper investigates the quantifier "there exist unboundedly many" in the context of first-order arithmetic. An alternative axiomatization is found for Peano arithmetic based on an axiom schema of regularity: The union of boundedly many bounded sets is bounded. We also obtain combinatorial equivalents of certain second-order theories associated with cuts in nonstandard models of arithmetic.

We prove that: • if there is a model of I∆₀ + ¬ exp with cofinal Σ₁-definable elements and a Σ₁ truth definition for Σ₁ sentences, then I∆₀ + ¬ exp +¬BΣ₁ is consistent, • there is a model of I∆₀ Ω₁ + ¬ exp with cofinal Σ₁-definable elements, both a Σ₂ and a ∏₂ truth definition for Σ₁ sentences, and for each n > 2, a Σ n truth definition for Σ n sentences. The latter result is obtained by (...) constructing a model with a recursive truth-preserving translation of Σ₁ sentences into boolean combinations of $\exists \sum {\begin{array}{*{20}{c}} h \\ 0 \\ \end{array} } $ sentences. We also present an old but previously unpublished proof of the consistency of I∆₀ + ¬ exp + ¬BΣ₁ under the assumption that the size parameter in Lessan's ∆₀ universal formula is optimal. We then discuss a possible reason why proving the consistency of I∆₀ + ¬ exp + ¬BΣ₁ unconditionally has turned out to be so difficult. (shrink)

“A great story, full of twists and turns.... Careers made and ruined, departments torn apart, writing programs turned into sensitivity seminars, political witch hunts, public opprobrium, ignorant media attacks, the whole ball of wax. Read it and laugh or read it and weep. I can hardly wait for the movie.” —Stanley Fish, _Think Again, New York Times_ “In such a difficult genre, full of traps and obstacles, French Theory is a success and a remarkable book in every respect: it is (...) fair, balanced, and informed. I am sure this book will become the reference on both sides of the Atlantic.” —Jacques Derrida “The Atlantic Ocean has two sides, and so does French Theory. Reinvented in America and betrayed in its own country, it has become the most radical intellectual movement in the West with global reach, rewriting Marx in light of late capitalism. Breathtakingly moving back and forth between the two cultures, Francois Cusset takes us through a dazzling intellectual adventure that illuminates the past thirty years, and many more decades to come.” —Sylvere Lotringer During the last three decades of the twentieth century, a disparate group of radical French thinkers achieved an improbable level of influence and fame in the United States. Compared by at least one journalist to the British rock ‘n’ roll invasion, the arrival of works by Michel Foucault, Jacques Derrida, Jean-François Lyotard, Jean Baudrillard, Gilles Deleuze, and Félix Guattari on American shores in the late 1970s and 1980s caused a sensation. Outside the academy, “French theory” had a profound impact on the era’s emerging identity politics while also becoming, in the 1980s, the target of right-wing propagandists. At the same time in academic departments across the country, their poststructuralist form of radical suspicion transformed disciplines from literature to anthropology to architecture. By the 1990s, French theory was woven deeply into America’s cultural and intellectual fabric. French Theory is the first comprehensive account of the American fortunes of these unlikely philosophical celebrities. François Cusset looks at why America proved to be such fertile ground for French theory, how such demanding writings could become so widely influential, and the peculiarly American readings of these works. Reveling in the gossipy history, Cusset also provides a lively exploration of the many provocative critical practices inspired by French theory. Ultimately, he dares to shine a bright light on the exultation of these thinkers to assess the relevance of critical theory to social and political activism today-showing, finally, how French theory has become inextricably bound with American life. François Cusset, a writer and intellectual historian, teaches contemporary French thought in Paris at the Institut d’Etudes Politiques and at Columbia University’s Reid Hall. His books include Queer Critics and La Décennie. Jeff Fort is assistant professor of French at the University of California, Davis. He has translated works by Maurice Blanchot, Jean Genet, and Jean-Luc Nancy. (shrink)

The commonplace image of Heidegger is of a philosopher firmly rooted, not in the city of Freiburg in which much of his life was spent, but in the Alemannic-Schwabian countryside around the village of Messkirch in which he was born. It would seem that the distance between Heidegger and Benjamin, between Messkirch and Berlin or Paris could not be greater. But to what extent are Heidegger's own personal predilections for the provincial and the bauerlich actually tied to the philosophical (...) positions that he developed? Might it be the case that the city, perhaps even more than the countryside, has to play a central role in any serious attempt to think through the implications of Heidegger's thought of being? This presentation will explore how Heidegger might find h imself in Benjamin's city, and of the place of the city in Heidegger's own thought, with the aim of shedding light, not only on Heidegger's thought, but also on that of Benjamin himself.

O lugar comum, no que tange à imagem de Heidegger, é a de um filósofo firmemente enraizado, não na cidade de Freiburg, na qual passou grande parte de sua vida, mas na região rural alemânico-suábia, nos arredores do povoado de Messkirch, onde nasceu. Poderia parecer que a distância entre Heidegger e Benjamin, entre Messkirch e Berlim, ou Paris, não poderia ser maior. Mas até que ponto estão as predileções pessoais de Heidegger pelo provinciano e o bauerlich de fato ligadas (...) às posições filosóficas que ele desenvolveu? Poderia ser este o caso, de que a cidade, talvez ainda mais do que o campo, devesse desempenhar um papel central em qualquer tentativa séria de se pensar até o fim as implicações do pensamento de Heidegger sobre o ser? Esta apresentação investigará como Heidegger se sentiria na cidade de Benjamin, bem como o lugar da cidade no pensamento do próprio Heidegger, com o propósito de lançar luz não apenas sobre o pensamento de Heidegger, mas também sobre o do próprio Benjamin.The commonplace image of Heidegger is of a philosopher firmly rooted, not in the city of Freiburg in which much of his life was spent, but in the Alemannic-Schwabian countryside around the village of Messkirch in which he was born.

Most people are skeptical of the claim that the expectation that a person would have a life that would be well worth living provides a reason to cause that person to exist. In this essay I argue that to cause such a person to exist would be to confer a benefit of a noncomparative kind and that there is a moral reason to bestow benefits of this kind. But this conclusion raises many problems, among which is that it must be (...) determined how the benefits conferred on people by causing them to exist weigh against comparable benefits conferred on existing people. In particular, might the reason to cause people to exist ever outweigh the reason to save the lives of existing people? (shrink)

In 2020, COVID-19, the Australia bushfires, and other global threats served as vivid reminders that human and nonhuman fates are increasingly linked. Human use of nonhuman animals contributes to pandemics, climate change, and other global threats which, in turn, contribute to biodiversity loss, ecosystem collapse, and nonhuman suffering. Jeff Sebo argues that humans have a moral responsibility to include animals in global health and environmental policy. In particular, we should reduce our use of animals as part of our pandemic (...) and climate change mitigation efforts and increase our support for animals as part of our adaptation efforts. Applying and extending frameworks such as One Health and the Green New Deal, Sebo calls for reducing support for factory farming, deforestation, and the wildlife trade; increasing support for humane, healthful, and sustainable alternatives; and considering human and nonhuman needs holistically. Sebo also considers connections with practical issues such as education, employment, social services, and infrastructure, as well as with theoretical issues such as well-being, moral status, political status, and population ethics. In all cases, he shows that these issues are both important and complex, and that we should neither underestimate our responsibilities because of our limitations, nor underestimate our limitations because of our responsibilities. Both an urgent call to action and a survey of what ethical and effective action requires, Saving Animals, Saving Ourselves is an invaluable resource for scholars, advocates, policy-makers, and anyone interested in what kind of world we should attempt to build and how.

This book provides an original and provocative combination of ethnomethodological analysis and the concepts of linguistic philosophy with a breadth and clarity unusual in this field of writing. It is designed to be read by sociologists, psychologists and philosophers and concerns itself with the contributions of Wittgenstein, defending the claim for his relevance to the human sciences. However, this book goes some way beyond the usual limitations of such interdisciplinary works by outlining some empirical applications of ideas derived from the (...) Wittgenstein tradition.

This paper argues against two prominent accounts of what it is to "promote a desire," found in the work of Stephen Finlay and Mark Schroeder.

However much one may wish for nonviolent solutions to the problems of unjust and unrestrained human violence that Glover explores in Humanity, some of those problems at present require violent responses. One cannot read his account of the Clinton administration’s campaign to sabotage efforts to stop the massacre in Rwanda in 1994 – a campaign motivated by fear that American involvement would cost American lives and therefore votes – without concluding that Glover himself believes that military intervention was morally required (...) in that case. Military intervention in another state that is intended to stop one group within that state from brutally persecuting or violating the human rights of members of another group is now known as “humanitarian intervention.” Those against whom the intervention is directed are almost always the government and its supporters, though this is not a necessary feature of humanitarian intervention. It is, however, a conceptual condition of humanitarian intervention that it does not occur at the request or with the consent of the government. The use of force within another state with the consent of the government counts as assistance rather than intervention. The principal reason that humanitarian intervention is contentious is that it seems to violate the target state’s sovereign right to control its own domestic affairs. Because humanitarian intervention is a response to human rights violations within the target state, it is regarded as altogether different from wars of defense against aggression. Indeed, since aggression is normally understood to be war against a state that.. (shrink)

There are many algorithm texts that provide lots of well-polished code and proofs of correctness. Instead, this book presents insights, notations, and analogies to help the novice describe and think about algorithms like an expert. By looking at both the big picture and easy step-by-step methods for developing algorithms, the author helps students avoid the common pitfalls. He stresses paradigms such as loop invariants and recursion to unify a huge range of algorithms into a few meta-algorithms. Part of the goal (...) is to teach the students to think abstractly. Without getting bogged with formal proofs, the book fosters a deeper understanding of how and why each algorithm works. These insights are presented in a slow and clear manner accessible to second- or third-year students of computer science, preparing them to find their own innovative ways to solve problems. (shrink)

I argue that Husserlian phenomenology is metaphysically neutral, in the sense of being compatible with multiple metaphysical frameworks. For example, though Husserl dismisses the concept of an unknowable thing in itself as “material nonsense”, I argue that the concept is coherent and that the existence of such things is compatible with Husserl’s phenomenology. I defend this metaphysical neutrality approach against a number of objections and consider some of its implications for Husserl interpretation.

Promotion is the relation between an act and a desire that obtains when the act advances or serves the desire. Under what conditions does an act promote a desire? Probabilistic accounts of promotion, the most prominent accounts, analyze promotion in terms of an increase in the probability of the desire’s satisfaction. In this paper, we clarify the promotion relation and explain why probabilistic accounts are attractive. Then we identify two questions probabilistic accounts must answer: the Baseline Question and the Interpretation (...) Question. We discuss and reject the three answers to the Baseline Question found in the literature, and explain the challenge future attempts at answering this question will face. Proponents of probabilistic accounts have not adequately addressed the Interpretation Question. We survey three answers to this question, finding each unsatisfactory. We conclude that no satisfactory probabilistic account has yet been offered, and that there are significant hurdles to providing one in the future. (shrink)

According to our traditional conception of agency, most human beings are agents and most, if not all, nonhuman animals are not. However, recent developments in philosophy and psychology have made it clear that we need more than one conception of agency, since human and nonhuman animals are capable of thinking and acting in more than one kind of way. In this paper, I make a distinction between perceptual and propositional agency, and I argue that many nonhuman animals are perceptual agents (...) and that many human beings are both kinds of agent. I then argue that, insofar as human and nonhuman animals exercise the same kind of agency, they have the same kind of moral status, and I explore some of the moral implications of this idea.

Source Hybridism about practical reasons is the position that facts that constitute reasons sometimes derive their normative force from external metaphysical grounds, and sometimes from internal. Although historically less popular than either Source Internalism or Source Externalism, hybridism has lately begun to garner more attention. Here, I further the hybridist's cause by defending Source Hybridism from three objections. I argue that we are not warranted in rejecting hybridism for any of the following reasons: that hybridists cannot provide an account of (...) normative weight, that hybridists are committed to implausible results concerning practical deliberation, or that Source Hybridism is objectionably unparsimonious.

In this article, I articulate and respond to an epistemological challenge to meta-normative realism. The challenge has it that, if realism about the normative is correct, and if evolutionary forces have significantly influenced our normative judgments, then it would be a remarkable coincidence if the content of the normative facts and our normative judgments were aligned. I criticize David Enoch's recent attempt to meet this challenge, but provide an alternative response that is structurally similar. I argue that if realism is (...) correct, then it would be remarkable if the content of our normative judgments and the normative facts were not significantly aligned. (shrink)

The leitmotif of Freedom in Response, as the title suggests, is a reasoned exposition of the nature of freedom, as it is presented in the Bible and developed by such later theologians as Martin Luther. Oswald Bayer considers Luther's teachings on pastoral care, marriage, and the three estates, bringing in Kant and Hegel as conversation partners, together with Kant's friend and critic, the innovative theologian and philosopher Johann Georg Hamann. Oswald Bayer is a major contemporary Lutheran theologian, but so far (...) little of his work has been translated from German into English. This selection of essays indicates the depth and range of his thought on issues relating to theological ethics. (shrink)

Aron Gurwitsch’s theory of the structure and dynamics of consciousness has much to offer contemporary theorizing about consciousness and its basis in the embodied brain. On Gurwitsch’s account, as we develop it, the field of consciousness has a variable sized focus or "theme" of attention surrounded by a structured periphery of inattentional contents. As the field evolves, its contents change their status, sometimes smoothly, sometimes abruptly. Inner thoughts, a sense of one’s body, and the physical environment are dominant field contents. (...) These ideas can be linked with (and help unify) contemporary theories about the neural correlates of consciousness, inattention, the small world structure of the brain, meta-stable dynamics, embodied cognition, and predictive coding in the brain.

In this paper I ask how we should treat other beings in cases of uncertainty about sentience. I evaluate three options: an incautionary principle that permits us to treat other beings as non-sentient, a precautionary principle that requires us to treat other beings as sentient, and an expected value principle that requires us to multiply our subjective probability that other beings are sentient by the amount of moral value they would have if they were. I then draw three conclusions. First, (...) the precautionary and expected value principles are more plausible than the incautionary principle. Second, if we accept a precautionary or expected value principle, then we morally ought to treat many beings as having at least partial moral status. Third, if we morally ought to treat many beings as having at least partial moral status, then morality involves more cluelessness and demandingness than we might have thought. (shrink)

This book brings together, for the first time in one volume, key articles on faith development theory, originally published in religious and secular journals in America, Australia, and Europe. Written by internationally recognized scholars, the essays discuss faith development in relation to such things as interview data, pastoral care, and Christian education.
