In this paper, I challenge a familiar argument -- a composite of arguments in the literature -- for the view that “Why be moral?” is a pseudo-question. I do so by refuting a component of that argument, a component that is not only crucial to the argument but important in its own right. That component concerns the status of moral reasons in replies to “Why be moral?”; consequently, this paper concerns reasons and rationality no less than it concerns morality. (...) The work I devote to those topics shows not only that the argument I address is unsound, but that the conclusion of that argument is false. “Why be moral?” is no pseudo-question. (shrink)

Many arguments have been advanced for the view that "Why be moral?" is a pseudo-question. In this paper I address one of the most widely known and influential of them, one that comes from John Hospers and J. C. Thornton. I do so partly because, strangely, an important phase of that argument has escaped close attention. It warrants such attention because, firstly, not only is it important to the argument in which it appears, it is important in wider respects. (...) For instance, if it is sound it has weighty consequences even if the argument in which it figures fails. Secondly, it is not sound; it succumbs to a simple objection. (shrink)

We present a game mechanic called pseudo-visibility for games inhabited by non-player characters (NPCs) driven by reinforcement learning (RL). NPCs are incentivized to pretend they cannot see pseudo-visible players: the training environment simulates an NPC to determine how the NPC would act if the pseudo-visible player were invisible, and penalizes the NPC for acting differently. NPCs are thereby trained to selectively ignore pseudo-visible players, except when they judge that the reaction penalty is an acceptable tradeoff (e.g., (...) a guard might accept the penalty in order to protect a treasure because losing the treasure would hurt even more). We describe an RL agent transformation which allows RL agents that would not otherwise do so to perform some limited self-reflection to learn the training environments in question. (shrink)

Following W.V. Quine’s lead, many metaphysicians consider ontology to be concerned primarily with existential questions of the form, “What is there?”. Moreover, if the position advanced by Rudolf Carnap, in his seminal essay, “Empiricism, Semantics, and Ontology ”, is correct, then many of these existential ontological questions ought to be classified as either trivially answerable or as “pseudo-questions”. One may justifiably wonder, however, whether the Quinean and Carnapian perspective on ontology really does justice to many of (...) the most central concerns of this discipline. This chapter argues, by considering a particular ontological dispute between two different kinds of trope theorists, that some of the most interesting and important debates which properly belong to the study of being, whether we call it “metaphysics” or “ ontology ”, do not concern existential questions at all; rather, such disputes in some cases focus on non-existential disagreements over questions of fundamentality.

This paper raises some questions about the formalization of sentences containing ‘if’ or similar expressions. In particular, it focuses on three kinds of sentences that resemble conditionals in some respects but exhibit distinctive logical features that deserve separate consideration: whether-or-not sentences, biscuit conditionals, and concessive conditionals. As will be suggested, the examples discussed show in different ways that an adequate formalization of a sentence must take into account the content expressed by the sentence. This upshot is arguably what one (...) should expect on the view that logical form is determined by truth conditions. (shrink)

In his early philosophy as well as in his middle period, Wittgenstein holds a purely syntactic view of logic and mathematics. However, his syntactic foundation of logic and mathematics is opposed to the axiomatic approach of modern mathematical logic. The object of Wittgenstein’s approach is not the representation of mathematical properties within a logical axiomatic system, but their representation by a symbolism that identifies the properties in question by its syntactic features. It rests on his distinction of descriptions and operations; (...) its aim is to reduce mathematics to operations. This paper illustrates Wittgenstein’s approach by examining his discussion of irrational numbers. (shrink)

This essay is part of larger project in which I attempt to show that Western formal logic, from its inception in Aristotle onward, has both been partially constituted by, and partially constitutive of, what has become known as racism. More specifically, (a) racist/quasi-racist/proto-racist political forces were part of the impetus for logic’s attempt to classify the world into mutually exclusive, hierarchically-valued categories in the first place; and (b) these classifications, in turn, have been deployed throughout history to justify and empower (...) racism/quasi-racism/proto-racism. In other words, (a) an important part of the chaos and messiness that so troubles logic has been the natural bio-cultural diversity of human beings as described by concepts such as race and ethnicity; and (b) once these concepts were historically in place, taken for granted, buttressed with pseudo-science, and had their origins forgotten, they became tools for the oppression of diverse human groups. The central thesis of this essay is that close readings of a variety of Leibniz’s writings (including several essays and one letter) will reveal a pattern of mutual dependency and creation in regard to logic and racism in Leibniz. My conclusion will be that there is a meaningful connection between logic and racism (or at least between logic and politics in general) in Leibniz such that one should be skeptical of his logic’s claim to offer transparent and neutral descriptions of the world as well as imperatives for action. Put differently, I want to ask the following specific question: how do Leibniz’s own racially-informed political goals, along with the emergence of race-centric European colonialism, both invest and disguise themselves within Leibniz’s mathematizing of logic?

Logic is about reasoning, or so the story goes. This thesis looks at the concept of logic, what it is, and what claims of correctness of logics amount to. The concept of logic is not a settled matter, and has not been throughout the history of it as a notion. Tools from conceptual analysis aid in this historical venture. Once the unsettledness of logic is established we see the repercussions in current debates in the philosophy of logic. Much of the (...) battle over the ‘one true logic’ is conceptually talking past each other. The theory of logics-as-formalizations is presented as a conceptually open theory of logic which is Carnapian in flavour and grounding. Rudolf Carnap’s notions surrounding ‘external’ and ‘pseudo-questions’ about linguistic frameworks apply to formalizations, thus logics, as well. An account of what formalizations are, a more structured sub-set of modelling, is given to ground the claim that logics are formalizations. Finally, a novel account of correctness, the COFE framework, is developed which allows the notions of logical monism, pluralism and nihilism to be more precisely formulated than they currently are in the discourse.

The question of how to demarcate science from pseudo-science commands relatively little attention today. In the philosophy of logic, by contrast, the problem of demarcating the logical constants is less skeptically regarded. In aesthetics, where the problem is how to demarcate art from non-art, the question as to whether the problem is a real one or a pseudo-problem also continues to be debated. This paper discusses the hypothesis that the demarcation questions in these three areas are parallel, (...) or at least similar enough to be interesting. Some arguments for the conclusion that the demarcation problem is a pseudo-problem are considered, as are some demarcation proposals of a deflationist or minimalist sort. All are found wanting.

Reductionists about knowledge-wh hold that "s knows-wh" (e.g. "John knows who stole his car") is reducible to "there is a proposition p such that s knows that p, and p answers the indirect question of the wh-clause." Anti-reductionists hold that "s knows-wh" is reducible to "s knows that p, as the true answer to the indirect question of the wh-clause." I argue that both of these positions are defective. I then offer a new analysis of knowledge-wh as a special kind (...) of de re knowledge. (shrink)

[What It’s Like, or What It’s About? The Place of Consciousness in the Material World] Summary: The book is both a survey of the contemporary debate and a defense of a distinctive position. Most philosophers nowadays assume that the focus of the philosophy of consciousness, its shared explanandum, is a certain property of experience variously called “phenomenal character,” “qualitative character,” “qualia” or “phenomenology,” understood in terms of what it is like to undergo the experience in question. Consciousness as defined in (...) terms of its phenomenal aspect is often called “phenomenal consciousness.” The major issue that occupies most thinkers is whether this phenomenal character happens to be a physical property, or whether it is rather sui generis. Those who believe the former are materialists; those who conclude the latter are dualists. As the currently dominant metaphysic is materialism – also sometimes called physicalism – the challenge appears to be to slot phenomenal properties among the physical properties that ultimately make up the world. David Chalmers argued powerfully that we can go very far in situating many mental properties in the physical world – namely, the properties that can be understood in functional terms – but that phenomenal properties resist such a treatment. Chalmers calls this “the hard problem” of consciousness. But there are also some quite powerful positive arguments for dualism. The two most influential ones are the modal argument, also offered by Chalmers, and the knowledge argument invented by Frank Jackson. Chalmers invites us to conceive of creatures that are exactly like human beings – physically, functionally, behaviorally – only bereft of phenomenal consciousness. If such creatures are conceivable, says Chalmers, they are metaphysically possible. And if they are metaphysically possible, materialism is false. Jackson, for his part, suggests we imagine Mary who has spent her entire life inside a black-and-white room and has seen the world through a black-and-white TV screen. But she also happens to know everything there is to know about the physics of color. And yet, Jackson suggests that once Mary is finally released from her room and sees a lawn outside, she learns something new: that this is what it is like to experience green color. The current work on consciousness is by and large characterized by attempts to answer these two dualistic arguments. I try to make sense of the positions within the domain of philosophy of consciousness by means of two major distinctions that mutually intersect. First, there is a distinction between dualism and materialism. An apparent third alternative currently on offer, the so-called Russellian monism, is unstable, collapsing into either dualism (panpsychism) or materialism (Russellian physicalism). Materialism comes in two main flavors: either the a posteriori physicalism, which detects an epistemic gap between phenomenal and physical truths, hence denying that the former could be derived from the latter; or the a priori physicalism, which does not acknowledge any such obstacle. The second major distinction is between phenomenism and representationalism. It’s true that Ned Block, who introduced this contrast, meant to distinguish between two kinds of materialism. But I believe that the distinction actually intersects the one between materialism and dualism. We thus arrive at a table with six slots, representing six main positions in the philosophy of consciousness: (1) dualist phenomenism (Chalmers, the early Jackson, and Tyler Burge); (2) dualist representationalism (René Descartes); (3) aposteriori materialist phenomenism (Block); (4) a posteriori materialist representationalism (Michael Tye, Fred Dretske, David Rosenthal); (5) a priori materialist phenomenism (David Lewis); and (6) a priori materialist representationalism (Daniel Dennett, Derk Pereboom). However, this scheme is in fact somewhat misleading. It is true that Dennett is usually classified as an apriori materialist (or, more precisely an apriori materialist representationalist), but I believe that needs to be corrected. In order to understand why, I first analyze varieties of materialist representationalism in detail, in particular various construals of phenomenal character in terms of representation, or intentionality, which includes a discussion of the identity of its content (the issue of externalism). By contrast, Dennett rejects the concept of phenomenal character. Consciousness has no intrinsic, publicly inaccessible properties. On that ground, Dennett builds an empirical, fully functionalist theory of consciousness, which he also tries to integrate within a general Darwinian framework. From that point of view, one can contrast Dennettian and representationalist views on the issue of animal consciousness. In addition to his rejection of phenomenal character, Dennett also abstains from the regular metaphysical departure point of regular materialism. He does not so much ask how an enigmatic property of consciousness fits an antecedently characterized world, but rather how far we can investigate all aspects of the world, including consciousness, using the scientific method. He is thus a methodological naturalist, rather than a metaphysical materialist. While this approach removes obstacles to the science of consciousness, it does not solve what might be called “the hardest problem” – of intentionality, not phenomenal consciousness. The hardest problem consists in the fact that our intentional discourse involves conflicting commitments that prevent a coherent metaphysic of representational states. However, it does not follow that we should give up on this discourse as a theoretical means of reduction as well as a practical tool of explanation. But it might be that intentional discourse is a somewhat pseudo one. (shrink)

The traditional use of the expression 'pseudoproblem' is analysed in order to clarify the talk of pseudoproblems and related phenomena. The goal is to produce a philosophically serviceable terminology that stays true to its historical roots. This explicative study is inspired by and makes use of the method of logical reconstruction. Since pseudoproblems are usually expressed by pseudoquestions a formal language of questions is presented as a possible reconstruction language for alleged pseudoproblems. The study yields an informal theory of (...) pseudoproblems whose presuppositions are critically investigated right away. At least one result remains: Claims of pseudoproblemship and their refutations must not be voiced casually - they are to be relativized and need substantial interpretive effort. (shrink)

L’étude proposée ici se déroulera en trois moments. Il s’agit, dans un premier temps, de revenir sur la manière dont la question du rapport entre vérité et fiction est posée dans le Traité des sensations de Condillac. Il faut rappeler la justification du recours à la fiction d’une statue gagnant un sens à la fois dans le cadre d’une analyse portant sur l’origine des idées, c’est-à-dire du recours à l’imagination dans le contexte d’une enquête métaphysique ressortissant à la raison. Dans (...) un second temps, il faut se pencher sur ce qu’on peut appeler la fonction du romanesque dans le dispositif global de la fiction condillacienne, c’est-à-dire, non pas seulement ce qui revient au fictionnel, mais en propre à un art narratif visant des séquences événementielles singulières. Enfin, on terminera par quelques remarques sur ce qui est très souvent négligé dans les études portant sur ce texte – du moins en philosophie, et qui ne manque pourtant pas d’être curieux, à savoir, justement, son inscription dans le registre des Mémoires ou des pseudo-Mémoires.

The claim that ―concepts serve as rules for the synthesis of representations‖ is understood by the mainstream of Kant‘s scholarship as if categories and concepts, in general, are conditions for the constitution of objects out of the manifold of sensations devoid of reference. That is the claim that I wish to question here. The claim comes in different flavors and formulations. Still, none of them are relevant here. I aim to provide an alternative account for the claim that ―the representation (...) makes the object possible.‖ I argue that the traditional view represents a solution to what I call the pseudo-problem of intentionality, namely to account for how a representation of something emerges out of a manifold of sensations devoid of reference. Yet, the intentionality problem is a misunderstanding of what I call the recognition thesis: the role of concepts is to provide the rules for the (mind-dependent) recognition (Erkenntnis) of the mind-independent existence of transcendental objects (noumena). ―The representation makes the object possible in the relevant sense that only by means of concepts can we recognize that what is sense-dependently represented actually exists mind-independently as transcendental objects or noumena in the negative sense. My view is embedded in the framework of what today is called ―Kantian Nonceptualism‖. Still, my view is neither a simple re-statement of Kantian Nonconceptualism nor depends on it. It is independently grounded on what Kant calls ―Erkenntnis‖. (shrink)

This book is an introduction to The Metaphysicist, the second Information Philosopher website, a work in progress on some classical questions in philosophy that 20th-century logical positivists and analytic language philosophers dis-solved as pseudo-problems. -/- The Metaphysicist analyzes the information content in twenty classic problems in metaphysics - Abstract Entities, Being and Becoming, Causality, Chance, Change, Coinciding Objects, Composition (Parts and Wholes), Constitution, Free Will or Determinism, God and Immortality, Identity, Individuation, Mind-Body Problem, Modality, Necessity or Contingency, Persistence, (...) Possibility and Actuality, Space and Time, Truth, Universals, Vagueness, and the 20th-century problem of WaveParticle Duality. -/- The Metaphysicist also includes pages on the classic paradoxes and puzzles used for millennia to wrestle with these metaphysical problems The Debtor’s Paradox, Dion and Theon, The Growing Argument, The Infinite Regress, The Problem of the Many, The Ship of Theseus, The Sorites Puzzle, The Statue and the Clay, and Tibbles, the Cat. -/- Information philosophy is a new philosophical methodology that goes “beyond logic and language” to the underlying information structures in the cosmos, in the world, in biological systems, and in the human mind - structures without which logic, language, and science would be impossible.

G. W. Leibniz developed a new model for rational decision-making which is suited to complicated decisions, where goods do not rule each other out, but compete with each other. In such cases the deliberator has to consider all of the goods and pick the ones that contribute most to the desired goal which in Leibniz’s system is ultimately the advancement of universal perfection. The inclinations to particular goods can be seen as vectors leading to different directions much like forces in (...) Leibniz’s dynamics. The vectorial model of rational decision-making is related to Leibniz’s work with metaphysical physics and the calculus of variations and is a heuristic tool which helps in finding reasonable combinations – in ideal cases optimums - between competing goods. By applying the model, the decision-maker can map and compare outcomes of combinations of goods in question and practice a kind of pseudo-mechanical arithmetic of reasons. A central feature of the model is the possibility to employ geometrical figures to help the conceptualization. In this paper I present the vectorial model, examine its applications in practical cases from political theory, jurisprudence and ethics Leibniz presented, and compare the model to recent theories of acting under uncertainty, such as bounded rationality and optimizing under constraints.

In this paper I argue that the debate between the so-called “presentists” – according to whom only the present is real – and the “eternalists”, according to whom past present and future are equally real, has no ontological significance. In particular, once we carefully distinguish between a tensed and a tenseless sense of existence, it is difficult to find a single ontological claim on which the two parties could disagree. Since the choice of using a tense or a tenseless language (...) is dictated by purely pragmatic reasons, we should abstain from bringing to bear pseudo-debates generated by the “tensed” or the “tenseless theories” of time on the question of understanding the philosophical implications of contemporary spacetime theories, or notions like becoming, change and persistence in time.

Wittgenstein famously criticizes the philosophical practice of analyzing the meaning of words outside their ordinary use in everyday language, whereby often self-made pseudo-problems arise. In order to shed further light on Wittgenstein’s critique, this article makes use of the Remarks on the Philosophy of Psychology. First, starting from the remark in Vol. I, §52, his criticism of the philosophical method of selection and generalization is explained in detail. Next, I give a brief outline of Wittgenstein’s own way of philosophizing (...) by reference to a selection of comments concerning the use of psychological words in everyday language, which will also further elucidate his critique. Finally, I enter into the question which significance everyday language according to Wittgenstein has for philosophy. (shrink)

To Occamize a nominal expression N is to show that, despite grammatical appearances, N does not name, or denote, an entity. This article argues that the Occamization of ‘meaning,’ which was central to Gilbert Ryle’s meta-philosophy, had already been advanced by Franz Brentano. The core thesis of the article is that Brentano’s notion of ‘content,’ albeit different from that of linguistic rules, does a similar job of eliminating expendable entities. If the meaning of a linguistic expression is not an entity (...) at all, then the question as to what kind of entity it is—what I shall call the Locke-Frege problem—turns out to be a pseudo-problem and is better dispensed with.

While the inference problem is widely thought to be one of the most serious problems facing non-Humean accounts of laws, Jonathan Schaffer has argued that a primitivist response straightforwardly dissolves the problem. On this basis, he claims that the inference problem is really a pseudo-problem. Here I clarify the prospects of a primitivist response to the inference problem and their implications for the philosophical significance of the problem. I argue both that it is a substantial question whether this sort (...) of response ought to be accepted and that the inference problem, contra Schaffer, remains a significant problem with important implications for the non-Humean position. I also argue that this discussion indicates grounds to be wary about applying the Schaffer-style strategy of straightforwardly dissolving problems by stipulation to other philosophical problems.

When faced with the charge that a given concept of God is contradictory, the standard move among philosophers and theologians has been to try to explain away the contradiction and show that the concept of God in question is consistent. This has to do, of course, with the Law of Non-Contradiction (LNC). Another option, which has recently generated interest among logicians and analytic philosophers of religion, is to reject such a move as unnecessary and defend what might be called the (...) contradictory God thesis. To be sure, something close to that can be found in philosophers such as Pseudo-Dionysius, Thomas Aquinas and Nicolaus de Cusa. However, it is only recently that this approach has gained momentum, certainly driven by the contemporary advance of dialetheism and glut theoretic approaches in general, and paraconsistent logic. Needless to say, a standard move among defenders of the contradictory God thesis is to reject the LNC. The argumentation, however, is seldomly framed in conceptual terms. Instead, it is mostly framed in ontological terms, as God being a contradictory entity. From this perspective, the contradictory God thesis is the thesis that God is a contradictory object. My goal in this paper is to provide a conceptual assessment of the discussion surrounding the contradictory God thesis. To achieve this, I make use of a general and hopefully non-controversial meta-theory of concepts and adopt a semantic approach rather than a metaphysical one. Within this framework, I address the following questions: What are the different ways we can understand the contradictory God thesis? What grounds are there for rejecting a contradictory concept of God? What standard moves are available to defend oneself from such criticisms and how do they relate to the LNC? What challenges do they present? As a secondary goal, the paper introduces a novel defense of the contradictory God thesis, drawing on a specific interpretation of the theology of the 16th-century Indian thinker Jīva Gosvāmī, which does not necessitate the rejection of the LNC. I term this approach ‘non-dialetheic mystical contradictory theism.’. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:This Universalism Which Is Not OneLinda M. G. Zerilli (bio)Ernesto Laclau. Emancipation(s). London: Verso, 1996.Judging from the recent spate of publications devoted to the question of the universal, it appears that, in the view of some critics, we are witnessing a reevaluation of its dismantling in twentieth-century thought. One of the many oddities about this “return of the universal” 1 is the idea that contemporary engagements with it are (...) more or less of a piece, and that they reflect a growing consensus that poststructuralist political theories are incapable of generating a viable alternative to the collective fragmentation that characterizes late modernity. 2 The putative return to the universal marks, on this view, both a homecoming to Enlightenment ideals—purified of their more poisonous elements, of course—and a reconciliation of sorts between those who refuted these ideals and those who sought to realize them. Now that “we” all know and agree that poststructuralism is critically valuable but politically bankrupt; now that we all know and agree that the “old universal” was indeed a “pseudo-universal,” so the homecoming narrative goes; we can get on with the project of constructing a “new universal.” 3 This authentic universal would really be inclusive of all people, regardless of race, class, gender, sexuality, ethnicity, nationality, and whatever else attaches to the “embarrassing etcetera” that, as Judith [End Page 3] Butler reminds us, inevitably accompanies such gestures of acknowledging human diversity.Before signing on to this felicitous agreement about “the necessity of universalism,” we may wish to know whether we have anything like a minimal agreement in language, that is, whether we who speak of this universal are even speaking about the same thing. Apart from the not insignificant problem of translating from a philosophical to a political idiom, the whole question of this agreement is virtually occluded by the rush to rescue politics from the virulent particularisms that admit no common ground or sense of collective belonging. Presented in terms of the familiar binary couple, the choice between universalism and particularism seems settled by merely pointing to global and domestic political realities. Universalism is the only alternative to social fragmentation, wild child of the collapse of communism, the rise of deadly nationalisms, and the multiculturalist romance with particularism. To invoke the name of the universal in any affirmative sense is already to sign on to the political diagnosis and its solution.One of the many virtues of Ernesto Laclau’s Emancipation(s) is that it offers both an alternative to the binarisms spawned by the “return” to the universal (for example, false universalism/true universalism) and a trenchant critique of the original binary couple itself (universalism/ particularism). Demonstrating the imbrication of the universal and the particular, Laclau shows why it is a matter not of choosing one over the other but of articulating, in a scrupulously political sense, the relation between the two. He thus explicitly rejects the notion that this relation is one of mutual exclusion, and shows that the tendency to see it as just that has led to the impasse of the contemporary debate, an impasse that is glossed over in some highly visible academic cases by proclaiming the necessary return to the universal. Although the language of universalism as spoken by Laclau searches for some common ground between particularists and universalists, it is more by way of articulating their mutual contamination, that is, how each is rendered impure by the irreducible presence of the other.The Problem of UniversalsLaclau situates his collection of essays in the context of the increasingly polarized debate over multiculturalism, a debate in which the classical universalism of the philosophical tradition has come under serious question. Reading his essays, one comes to see the deep dependence of the entire contemporary discussion on this tradition, even when its metaphysical assumptions are explicitly rejected (as, say, in the work of Seyla Benhabib) or insufficiently comprehended (as in most of the popularized political discourse). Laclau’s book can help us to see that the political question of universalism cannot be posed properly as long as it remains tethered to the classical philosophical “problem of universals.” At stake in sorting out the affinities and...

On the notion of responsibility employed by John Passmore in his classic Man’s Responsibility for Nature, the relationship of responsibility can only hold between persons (human beings, subjects), or groups and communities of them, and other persons. And in this relationship the persons that are responsible 'to' other persons are responsible 'for' how their actions affect these other persons, not to the direct object of these actions (in this case: nature). If this is correct, we cannot be responsible to nature (...) without conceiving of it as a ‘pseudo-person’, as Passmore calls it. However, non-anthropocentric environmental ethics requires such a moral relationship. The question is, therefore, how this can be allowed in a metaphysically acceptable way. To answer this I first provide an account of what it means to stand in the relation of being ‘responsible to’. Next, I describe two major paradigmatic examples of the metaphysics of nature that perfectly match the thesis that we can, and should, be responsible to nature (the Spinoza-inspired view and the Gaia hypothesis). Unfortunately, they have to be rejected for common sense or naturalist reasons. Finally, I therefore defend a 'fictionalist' view of nature (as person-like) that allows for this relationship.

A survey of popular textbooks and websites on philosophy produces a ­remarkable consensus on the great problems facing philosophers from ­ancient to modern times. They typically include metaphysics - what is there?, the problem of knowledge - how do we know what exists?, the mind/body problem - can an immaterial mind move the material body?, the “hard problem” of consciousness, freedom of the will, theories of ethics - is there an objective universal Good?, and problems from theology - does God (...) exist?, is God responsible for evil? This book introduces the Information Philosopher website, a work in progress on several classic questions in philosophy that ­logical positivists and analytic language philosophers thought they could ­­dis-solve as logical puzzles, pseudo-problems, or conceptual errors.

En temps normal, les contrefactuels sont conçus comme produisant des énoncés portant sur des états de choses, mais des états de choses se trouvant dans des mondes simplement possibles ou alternes. Analysés ainsi, il s’avère que presque tous les contrefactuels sont incohérents. Tout contrefactuel analysé de la sorte exige qu’il y ait un monde métaphysiquement (et pas épistémiquement seulement) possible w où les lois sont les mêmes qu’ici, et où la quasi-totalité des faits sont les mêmes qu’ici. (Les différences factuelles (...) sont liées à l’antécédent et au conséquent du contrefactuel.) Mais comme je vais le montrer, cette exigence implique de manière typique la postulation de mondes dont on peut démontrer la nécessaire non-existence au moyen de déductions assez élémentaires. De plus, l’analyse des contrefactuels en termes de mondes possibles est coupable de circularité cachée. Analysés ainsi, les contrefactuels ne peuvent effectivement être compris qu’en termes de lois de la nature (les lois qui s’appliquent ici sont présupposées dans le monde hypothétique — excepté dans le cas atypique où le contrefactuel est également un contre-nomique). Mais il y a un argument répandu voulant que le concept de loi ne puisse pas être défini lui-même, sinon dans les termes de la notion de contrefactuel (une loi est, entre autres, quelque chose qui vient à l’appui des contrefactuels). Je donnerai une analyse purement épistémique des contrefactuels, déclarant que ce sont des propositions pseudo-probabilistes. Je déclarerai également que le type de probabilité en question peut être défini intégralement en termes de ce qui a été le cas (non pas de ce qui aurait été le cas, ni même de ce qui doit être le cas en un sens nomique.) Mon analyse n’est donc coupable d’aucune sorte de circularité. (shrink)

The editor's introduction discusses Clarence I. Lewis's conceptual pragmatism when compared with post-empiricist epistemology and argues that several Cartesian assumptions play a major role in the work, not unlike those of Logical Positivism. The suggestion is made that the Cartesian legacy still hidden in Logical Positivism turns out to be a rather heavy ballast for Lewis’s project of restructuring epistemology in a pragmatist key. More in detail, the sore point is the nature of inter-subjectivity. For Lewis, no less than for (...) the Logical Positivists at the time of the Protocols Controversy and Husserl in the Cartesian Meditations, this is a problem without a solution. The reason is that all these philosophers are apparently unable to realize that the existence of a plurality of knowing subjects cannot be treated at once both as a speculative problem and a methodological one. Lewis, thanks to his pragmatist approach both comes closer to the right answer and offers an even more naïve unsatisfactory solution to the pseudo-problem under discussion. The fact that he has clear in mind that inter-subjectivity means not only a plurality of linguistic utterances but also a co-existence of different kinds of practical behaviour. Eventually, the very idea of mind, the key-idea in the book, suffers from the above mentioned tension. In fact, if inter-subjective communication and action is considered at a methodological level, the very idea of mind would not need an analysis, and no kind of ‘reflexive’ analysis. Methodology might be limited to a ‘naïve’ level where the existence of the world and a plurality of subjects be taken as a bedrock of uncritically accepted evidence. Philosophical reflection on ultimate evidence, instead, would take a different approach, maybe the one Wittgenstein was putting into practice in the same years when Mind and the world order was written, namely it would be bound to question the very meaning of the idea of ‘mind’ as an undue fiction – the same carried out by Descartes – when he assumed the Cogito to be at once a body of self-evident truths and a thing or substance, the familiar Platonic idea of psyche or soul.

Many philosophers and scientists claim that there is a ‘hard problem of consciousness’, that qualia, phenomenology, or subjective experience cannot be fully understood with reductive methods of neuroscience and psychology, and that there is a fact of the matter as to ‘what it is like’ to be conscious and which entities are conscious (Chalmers, 1995). Eliminativism and related views such as illusionism argue against this; they claim that consciousness does not exist in the ways implied by everyday or scholarly language. (...) However, this debate has largely consisted of each side jousting analogies and intuitions against the other. Both sides remain unconvinced. To break through this impasse, I present _consciousness semanticism_, a novel eliminativist theory that sidesteps analogy and intuition. Instead, it is based on a direct, formal argument drawing from the tension between the vague semantics in definitions of consciousness such as ‘what it is like’ to be an entity (Nagel, 1975) and the precise meaning implied by questions such as, ‘Is this entity conscious?’ I argue that semanticism naturally extends to erode realist notions of other philosophical concepts, such as morality and free will. Formal argumentation from precise semantics exposes these as pseudo-problems and removes their apparent mysteriousness and intractability. (shrink)

Speaking for God has been part of religion for many years. However, science has come in the past few years to question that role or even our very ability to speak about God in general. My goal is to show that dogmatism, under any form, is wrong. And even though dogmatism had for a long time been associated with ill-intentioned religion, nowadays science has replaced religion in the throne of doctrinaire thinking. The point of the paper is to illustrate that (...) one-way thinking is never correct – most of the times a combination of science and religion, measurements and theoretical thinking, logic and intuition, is required to draw a conclusion about the most important philosophical questions. The paper establishes that exact sciences can be very useful, but they also have limits. The Religion-vs-Science problem is a pseudo-problem; logic and evidence can easily be used to defend theistic views. Both science and religion use common tools and methods and can be unified in a new way of thinking. This paper sets the foundations on how this can be achieved. The conclusion is that science and religion both complete our knowledge for the world, our understanding of humans and our purpose in life. Speaking about God is part of science as well as of religion. Only when we think of God as theologians and as scientists at the same time can we fully reach Him…. (shrink)

The article begins with an inquiry on St. Thomas Aquinas' theological framework of God in the Summa Theologica, as seen through the lenses of Pseudo Dionysius and Proclus Lycaeus, in the Light of Plato's dialectical exploration of the One in the Parmenides. We proceed to the similarities and differences between St. Thomas Aquinas’ theology and Plato’s philosophy in terms of the means through which the soul ascends towards the highest vision. Ideas of thinkers such as Democritus, Aristotle, Iamblichus, Thomas (...) Taylor, Friedrich Nietzsche and Martin Heidegger supported or provided counter arguments regarding these matters. The essay raises a significant question pertaining to the relationship between Plato’s thought with that of St. Thomas Aquinas’. (shrink)

Le présent travail s'inscrit à l'intersection de deux problèmes épistémologiques majeurs. D'une part, le problème de la démarcation scientifique, qui consiste à identifier ce qui distingue intrinsèquement un système (un énoncé, une théorie, ...) scientifique d'un système non scientifique ou pseudo-scientifique. D'autre part, le problème de l'unité épistémologique des sciences, qui consiste à se demander si toutes les disciplines à vocation scientifique peuvent être vues comme des instanciations d'une notion unique de la scientificité. Ces deux problèmes ont soulevé de (...) nombreux débats ayant mis en évidence un ensemble important de difficultés. Le terme « scientifique » désigne en effet des méthodes empiriques, des constructions théoriques et des pratiques de recherche si hétérogènes qu’il semble voué à l’échec d’en chercher une définition aisée à circonscrire. De plus, les objets des disciplines scientifiques sont eux-mêmes de natures très diverses, ce qui semble rendre pareillement caduque toute recherche d’un concept unique de science qui pourrait s’appliquer indépendamment de la discipline en question. Dans cette thèse, je me propose de prendre à contre-pied cet état de fait en soutenant la possibilité et la pertinence d'un modèle unitaire de la scientificité, tout en me restreignant à une approche épistémologique comparée entre les sciences physiques et les sciences sociales. Pour défendre mon propos, j’ai mobilisé deux types de réponses pouvant être opposées au constat présenté plus haut. D’une part, des réponses de principe, où j’examine et m’oppose à des arguments théoriques soutenant l’impossibilité ou en tout cas la difficulté de définir la scientificité en général, et la nécessité pour les sciences sociales de jouir d’une définition à part. D’autre part, je mobilise également des réponses par l’exemple. J’étudie alors plus en détail l’approche dite « analytique » en sociologie. Ce courant a cela d’intéressant pour mon propos qu’il ne semble pas nécessiter d’épistémologie alternative à celle ayant cours, par exemple, en physique ou en biologie, tout en prétendant bien produire des connaissances sur le monde social. Il s’agit donc d’un contre-exemple concret et manifeste de la thèse soutenant que la sociologie ne peut pas jouir du même type d’épistémologie que les autres disciplines. Plus concrètement, j’élabore un (méta-)modèle unitaire de la scientificité en me concentrant sur une unité d’analyse bien circonscrite : les modèles. Je distingue chez ses derniers, classiquement, deux composantes principales : une composante empirique, qui a pour vocation à identifier des régularités dans le réel auquel on a accès à travers des données, et une composante théorique, à visée explicative et classificatoire. Je propose alors de construire formellement un degré de scientificité global dans lequel se combinent la maximisation d’une certaine quantité d’information définie sur la composante empirique et un critère d’invariance structurelle défini sur la composante théorique. Ces diverses constructions, bien que formelles, permettent d’éclairer efficacement les questions épistémologiques que je me suis données au départ de mon travail, ce dernier ayant vocation à constituer une étape supplémentaire vers un modèle unitaire de la scientificité.

The purpose of this article is to introduce an innovative approach to the theoretical debate of the last two centuries on how to appropriately conceptualize modern democracy. The main argument that is being put forward by the analysis is that the common reliance on the assumption of pre-modern political philosophy, that democracy is a certain type of political regime or at least a form of rule, has become insufficient to cover the influence and scope of its modern meaning and practical (...) use. Political theory faces the risk of becoming misguided and prejudiced, if the problem of re-conceptualizing democracy is not taken seriously into account. The article tends to offer new insights on the ongoing democratic debate by focusing on one simple question: can modern democracy be understood in terms of a political regime or should it be viewed as a distinct entity? The field of study relevant to our analysis of democracy ranges from Enlightenment thinkers, such as J. J. Rousseau and Voltaire, to XIX–XX century political philosophers (like A. de Tocqueville and C. Schmitt) and some contemporary theorists, like P. Manent. The article starts with explanations, why it is important to look deeper into the conceptual difficulties of modern democracy and why political philosophy and its theories on political regimes are crucial for such a task. Parts 3–5 of the analysis tend to prove that the only way to appropriately understand modern democracy is to identify and question its basic assumptions: the sovereignty of the people and social equality. The final part of the article – part 6 – offers a critique of understanding modern democracy as a political regime. The critique identifies three main theoretical problems, inherent to the discussion on modern democracy, which make it difficult to avoid contradictions when applying the name “democratic” to various political regimes. The article concludes that: First, democracy is not a political regime in a pre-modern sense of the term, which is an assumption still widely taken for granted in political theory. Democracy should be seen as a universal principle of legitimization of power, which can be applied by various regimes. Second, political philosophy faces the danger of adopting an oversimplified understanding of democracy as merely an institutional form of rule (a view perpetuated by social sciences); as well as the danger of conceptualizing democracy as a substance-free and abstract ideal, applicable to all forms of government. Both of these concepts fail to acknowledge the scope of democracy and thus should not be seen as satisfactory. Third, theoretical discussions on democracy suffer from three conceptual shortcomings, which make it impossible to speak about democracy as a political regime. The three problems are: 1. a tendency to see democracy as an ideal concept with no need of practical grounding; 2. making democracy a formal concept with no need of references to its normative nor positive substance; 3. making democracy a pseudo-religious entity by imitating structural elements of Christian religion: faith in a universal nature of humans, an all-powerful sovereign (the people), messianic mission. Lastly, the article generalizes that political philosophy has an obligation to demystify the concept of democracy in order to re-emerge discussions about the substance of different political regimes. For this purpose the concept of loyalty should be taken into account. If we want to prove that a certain state corresponds to a certain political regime, we must try to understand why its subjects maintain loyalty to a specific form of rule. Only unprejudiced political philosophy is capable of such a task, that’s why it should avoid taking the concept of democracy for granted. (shrink)

The concept of ideology is central to the understanding of the many political, economic, social, and cultural processes that have occurred in the last two centuries. And yet, what is the nature of the different ideologies remains a vague, open, and much disputed question. Many political, sociological, and ideological studies have been devoted to ideology. Very little, on the other hand, has been done from the philosophical field. And this despite the fact that there are undoubtedly many philosophical questions (...) related to ideology and its role in modern industrialized societies. Just a few examples of ideology-related philosophical questions suffice to prove the point: What objects do ideologies deal with? Are the ideologies testable? Are there true ideologies? Do they evolve? How are ideologies related to societies? Is the existence of ideologies inevitable in modern societies? What is the relation of ideology to science? Is science just another kind of ideology? Are we, as human beings, innately predisposed to believe in ideologies? Or, instead, ideologies proliferate through indoctrination and propaganda? Are ideologies necessarily harmful?...and much more. In this article I try to answer some of these questions from a philosophical point of view, taking a materialist approach. I begin by characterizing ideology as a complex, multi-layered concept. Then, I briefly discuss the material systems on which ideological movements operate, that is, societies and concrete human groups. I identify at least 11 different elements that seem to be present in most ideologies, and I compare these characteristics with those of contemporary science and technology. Although some superficial similarities can be identified, there are deep differences that make ideology completely different from science. The similarities, however, are stronger with technology. Ideologies continually evolve with technological advances, social changes, and even with mere fashion. The current fragmentation of ideologies caused by the widespread use of new technologies and social networks has given rise to new phenomena of ideological propagation which, in my opinion, are very dangerous, particularly for open societies. I discuss these processes, within the context of the nature vs nurture debate, along with the question of whether we can get rid of ideologies. (shrink)

This paper details how ghost hunting, as a set of learning activities, can be used to enhance critical thinking and philosophy of science classes. We describe in some detail our own work with ghost hunting, and reflect on both intended and unintended consequences of this pedagogical choice. This choice was partly motivated by students’ lack of familiarity with science and philosophic questions about it. We offer reflections on our three different implementations of the ghost hunting activities. In addition, we (...) discuss the practical nuances of implementing these activities, as well the relation of ghost hunting to our course content, including informal fallacies and some models for scientific inference. We conclude that employing ghost hunting along-side traditional activities and content of critical thinking and philosophy of science offers a number of benefits, including being fun, increasing student attendance, enhancing student learning, and providing a platform for campus wide dialogues about philosophy.

In what is quite possibly the most famous passage of the De revolutionibus, Copernicus implies that nobody could ever place this supreme flaming torch that is the Sun in another or better place than that from which it can illuminate everything simultaneously, namely the centre of this extremely beautiful temple that is our world. Considering the fact that he leaves an interrogatory twist to this argument of convenience, and since he makes this statement without any justification as it seems entirely (...) evident to him, certain Copernicans choose to illustrate this by means of an analogy: if indeed the Sun must be positioned thus, it is because the most appropriate place for the torch intended to illuminate the room is at its centre, and not in one of its corners. Despite the heliosophy of the Renaissance having been shared by both geocentrists and Copernicans alike, this "torch" argument does not appear to have achieved much success: rarely adopted by the Copernican camp, it was even contested by some of them; as for the geocentrists, it held no appeal for them whatsoever. Did this argument of convenience therefore not benefit from the self-evidence attributed to it by Copernicus, and from, in his wake, it's continued support by a good many commentators? As is often the case when it comes to the history of thought, the pseudo-obviousness of this argument is merely the fruit of a blatant anachronism: presenting heliocentrism as the cosmological system that finally grants the Sun its worthy centrality by placing it in the centre of the room and not in a corner, is to ignore the fact that this star of the day already enjoyed, in geocentrism, a centrality esteemed to be perfectly in keeping with both its dignity and its inherent illuminative function. Having lost their grasp on this worldview that no longer belonged to them, the Copernicans thus put forward an argument which, for the geocentrists, is worthless. Yet they could have argued the objective superiority of their centrality over that accorded to the Sun by geocentrism: while the latter is only numerical, on a purely planetary scale, and frankly fictitious, the former is thoroughly spatial, of cosmic proportions and, at least on first approximation, very real. In order to produce arguments of convenience that could carry their own weight, the protagonists of the new cosmology would have benefited from getting to know the world vision of their adversaries a little better instead of addressing them from their own point of view; similarly, instead of treating as an obvious fact that which is only evident to one of the two parties present, historians of scientific thought would also be well advised to have a better understanding of the world vision of those who history now considers as the losers!

This paper generalizes rationalizability of a choice function by a single acyclic binary relation to rationalizability by a set of such relations. Rather than selecting those options in a menu that are maximal with respect to a single binary relation, a weakly pseudo-rationalizable choice function selects those options that are maximal with respect to at least one binary relation in a given set. I characterize the class of weakly pseudo-rationalizable choice functions in terms of simple functional properties. This (...) result also generalizes Aizerman and Malishevski's characterization of pseudo-rationalizable choice functions, that is, choice functions rationalizable by a set of total orders. (shrink)

This study aimed to determine the levels of pre-service teachers' nature of science (NOS) knowledge, assess their pseudo-scientific beliefs, and examine the relationship between aspects of their NOS knowledge and these beliefs. It also aimed to determine whether NOS knowledge and pseudo-scientific beliefs depended on the discipline and gender. A survey method was conducted in this study. Data were collected from 215 pre-service teachers who are being educated in different fields in a state university. Two different five-point Likert (...) scales were applied. Scale 1, which hasthree factors, measured pseudo-scientific beliefs, while Scale 2, which has seven factors, measured NOS knowledge. As a result, preservice teachers' NOS knowledge was found to be inadequate and their pseudoscientific beliefs were excessive. All factors of Scale 1 were positively correlated with each other, and they were correlated with some components of NOS knowledge. Significant differences were found between disciplines in the analysis of the factors of Scale 2; however, no significant differences were found between genders. (shrink)

In his Exhortation to Philosophy (Protrepticus), the Neoplatonic philosopher Iamblichus famously preserves material culled from lost works of ancient philosophy, including dialogues of Aristotle. He also preserves a work entitled On Wisdom and ascribed to the Pythagorean philosopher Archytas of Tarentum, who was a friend and challenger of Plato. The text On Wisdom is a later Hellenistic production, probably written in the 1st century BCE, but it presents an important piece in the puzzle of reconstructing Pythagoreanism for the Hellenistic and (...) Post-Hellenistic periods. On Wisdom provides ps-Archytas' views on the nature, pursuit, and purposes of philosophy, as well as the division of the parts of knowledge. This article presents the first complete modern translation into English and analysis of this work, whilst also explaining the precise ways in which its first critic, Iamblichus, appropriates its content to Neoplatonic theories.

Is all explanations causal explanation? Puzzles about barometer readings "explain" storms and shadow lengths "explaining" flagpole heights make it attractive to think so. Wesley Salmon (1984) has endorsed this causal thesis. One way to test this thesis is to assess the explanatory import of pseudo-processes. I do so by discussing the concept of heritability, which measures a pseudo-process, and one role it played in the theory of natural selection: explaining response to selection. This will show, not just that (...) heritability has heuristic or predictive utility, but that it can be explanatory. Possible responses to this case are also discussed. (shrink)

In his recent "Thomas vs. Thomas: A New Approach to Nagel's Bat Argument", Yujin Nagasawa interprets Thomas Nagel as making a certain argument against physicalism and objects that this argument transgresses a principle, laid down by Thomas Aquinas, according to which inability to perform a pseudo-task does not count against an omnipotence claim. Taking Nagasawa's interpretation of Nagel for granted, I distinguish different kinds of omnipotence claims and different kinds of pseudo-tasks, and on that basis show that Nagasawa's (...) criticism of Nagel is unsuccessful. I also show how his reflections do nonetheless point to a limitation of the approach he means to criticize. (shrink)

The ability to communicate in a specific language like Chinese typically indicates that the speaker understands the language. A counterexample to this belief is John Searle’s Chinese room experiment. It has been shown in this experiment that in certain circumstances we can communicate with a Chinese speaker without intuitively acknowledging that the Chinese language is understood in the conversation. In the present paper, we aim to present another counterexample showing that, in certain circumstances, we can communicate using a specific language (...) by converting its words to those of our natural language, and understand what is expressed using the language without understanding it. Using a specific conversion process introduced in the present paper, symbols and even sounds of a language like the Chinese language lose their original function and act as a tool to express one’s natural language. To better understand this, imagine the English language has another writing or phonological system in addition to its current writing system. (shrink)

Alors que le débat sur le caractère scientifique ou pseudo-scientifique de l’agriculture biodynamique occupe régulièrement le débat public, l’histoire et la philosophie des sciences ne semblent que très peu s’être emparées de ce sujet. La thèse défendue ici est double : tout d’abord, si l’agriculture biodynamique rencontre un relatif succès aujourd’hui, cela tient sans doute au fait que son théoricien, R. Steiner, a été un des premiers à critiquer le paradigme qui domine l’agronomie, ou en tout cas l’agriculture, depuis (...) plus d’un siècle. Cette critique semble d’ailleurs se maintenir dans ses motifs tout au long du XXe siècle, jusqu’à une certaine critique contemporaine de l’agro-industrie et de ses conséquences désastreuses sur l’environnement. Or, et c’est la seconde thèse défendue ici, cette critique semble méconnaître voire occulter la réalité des débats internes qui ont traversé l’agronomie au cours du XXe siècle et qui continuent de l’agiter aujourd’hui : l’agronomie système a ainsi par exemple intégré dans ses objets des éléments de l’agriculture biodynamique. Selon nous, le problème principal est que l’agronomie est souvent abordée selon une approche externaliste, qui doit impérativement être complétée par une approche internaliste afin tout d’abord de distinguer ce qui relève de la science et ce qui relève du mysticisme, et ensuite de saisir toute la richesse historique et épistémologique de l’agronomie.

This paper discusses continuity between ancient Pythagoreanism and the pseudo-Pythagorean writings, which began to appear after the end of the Pythagorean school ca. 350 BC. Relying on a combination of temporal, formal and substantial criteria, I divide Pseudopythagorica into three categories: 1) early Hellenistic writings ascribed to Pythagoras and his family members; 2) philosophical treatises written mostly, yet not exclusively, in pseudo-Doric from the turn of the first century BC under the names of real or fictional Pythagoreans; 3) (...) writings attributed to Pythagoras and his relatives that continued to appear in the late Hellenistic and Imperial periods. I will argue that all three categories of pseudepigrapha contain astonishingly little that is authentically Pythagorean. (shrink)

Drawing inspiration from the notion of evocation employed in inferential erotetic logic, we defend an ‘evoked questions norm’ on inquiring attitudes. According to this norm, it is rational to have an inquiring attitude concerning a question only if that question is evoked by your background information. We offer two arguments for this norm. First, we develop an argument from convergence. Insights from several independent literatures (20th-century ordinary-language philosophy, inferential erotetic logic, inquisitive epistemic logic, and contemporary zetetic epistemology) all converge (...) on the evoked questions norm. Second, we show that suitably interpreted, the evoked questions norm correctly predicts several underappreciated kinds of bad questions. It does this, in part, by recovering versions of previously defended ignorance and knowledge norms. Some of those bad questions cannot be predicted by either norm singly, but only when corporately taken to reflect a common normative category. We identify this category as evocation. (shrink)

ABSTRACT In order to explore what it means to pursue philosophical investigations for theological reasons, this paper argues that Ludwig Wittgenstein continues and corrects Pseudo-Denys’ project in The Divine Names. I first argue that The Divine Names should be interpreted as attempting to render human thought transparent to the divine by relativizing our concepts. The success of this project is compromised because the concept of ‘unity’ is not relativized. I then develop the claim that Wittgenstein does relativize unity in (...) a similar way and for similar religious reasons to Pseudo-Denys. As such, he can be read as continuing and correcting the Pseudo-Dionysian project. I conclude by reflecting on several of this argument’s implications for the relationship between philosophy and Christian systematic theology. (shrink)

My chapter aims to advance the debate on a problem often raised by philosophers who are skeptical of implied narrators in movies. This is the concern that positing such elusive narrators gives rise to absurd imaginings (Gaut 2004: 242; Carroll 2006: 179-180). -/- Friends of the implied cinematic narrator reply that the questions critics raise about the workings of the implied cinematic narrator are "silly ones" to ask. -/- I examine how the "absurd imaginings" problem arises for all the (...) central arguments for the elusive cinematic narrator and discuss why the questions critics pose about this narrator are legitimate ones to ask.

Choices confront us with questions. How we act depends on our answers to those questions. So the way our beliefs guide our choices is not just a function of their informational content, but also depends systematically on the questions those beliefs address. This paper gives a precise account of the interplay between choices, questions and beliefs, and harnesses this account to obtain a principled approach to the problem of deduction. The result is a novel theory of (...) belief-guided action that explains and predicts the decisions of agents who, like ourselves, fail to be logically omniscient: that is, of agents whose beliefs may not be deductively closed, or even consistent.

I provide a characterization of weakly pseudo-rationalizable choice functions---that is, choice functions rationalizable by a set of acyclic relations---in terms of hyper-relations satisfying certain properties. For those hyper-relations Nehring calls extended preference relations, the central characterizing condition is weaker than (hyper-relation) transitivity but stronger than (hyper-relation) acyclicity. Furthermore, the relevant type of hyper-relation can be represented as the intersection of a certain class of its extensions. These results generalize known, analogous results for path independent choice functions.

A number of logicians and philosophers have turned their attention in recent years to the problem of developing a logic of interrogatives. Their work has thrown a great deal of light on the formal properties of questions and question-sentences and has led also to interesting innovations in our understanding of the structures of performatives in general and, for example, in the theory of presuppositions. When, however, we examine the attempts of logicians such as Belnap or Åqvist to specify what, (...) precisely, a question is, or what it is to ask or raise a question, then what we are offered is somewhat less illuminating. Two alternative reductionist accounts seem in particular to have gained most favor: questions are identified either as special sorts of statements, or as special sorts of requests. As we hope will become clear in what follows, neither of these accounts is even nearly adequate; and matters are not improved if questions are identified, by force majeure, as combinations of statements and requests.
