Insight is a cognitive feature that is usually regarded as being generated by the neocortex and being present only in humans and possibly some closely related primates. In this essay we show that especially corvids display behavioral skills within the domains of object permanence, episodic memory, theory of mind, and tool use/causal reasoning that are insightful. These similarities between humans and corvids at the behavioral level are probably the result of a convergent evolution. Similarly, the telencephalic structures involved in higher (...) cognitive functions in both species show a high degree of similarity, although the forebrain of birds has no cortex-like lamination. The neural substrate for insight-related cognitive functions in mammals and birds is thus not necessarily based on a laminated cortical structure but can be generated by differently organized forebrains. Hence, neither is insight restricted to mammals, as predicted from a “scala naturae”, nor is the laminated cortex a prerequisite for the highest cognitive functions. (shrink)

It is not a coincidence that every red rose is coloured. No rose can be red without being coloured. A red rose is coloured in virtue of its being red, its being coloured is metaphysically explained by its being red. This is, at least in part, underwritten by what it is for the rose to be coloured, by the nature – or essence – of its being coloured. If this is right, then questions concerning possibility and (...) necessity, questions concerning metaphysical explanation, and questions concerning essence are systematically connected. This book proposes a unified account of metaphysical modality, grounding, and essence. It develops a semantic way to model essences as localised necessities that rule out worlds as impossible and uses it to account for grounding and metaphysical modality. (shrink)

Ideal epistemologists investigate the nature of pure epistemic rationality, abstracting away from human cognitive limitations. Non-ideal epistemologists investigate epistemic norms that are satisfiable by most humans, most of the time. Ideal epistemology faces a number of challenges, aimed at both its substantive commitments and its philosophical worth. This paper explains the relation between ideal and non-ideal epistemology, with the aim of justifying ideal epistemology. Its approach is meta-epistemological, focusing on the meaning and purpose of epistemic evaluations. I provide an account (...) on which the fundamental difference between ideal and non-ideal epistemic evaluations is that only the non-ideal epistemic ‘ought’ implies any substantive ‘can’. I argue that only ideal epistemic evaluations are ‘normatively robust’: they are neither conventional nor seriously context-sensitive. Non-ideal epistemic evaluations are normatively non-robust, exhibiting both conventionality and serious context-sensitivity from an interesting variety of distinct sources. For this reason, non-ideal epistemic evaluations won’t characterize the fundamental nature of epistemic rationality. Non-ideal epistemic rationality depends, not merely on what’s epistemically valuable, but also on modally contingent epistemic conventions and contextually contingent constraints on epistemic options. If we want a normatively robust theory of epistemic rationality, ideal epistemology is the only game in town. (shrink)

The Received View on quantum non-individuality is, roughly speaking, the view according to which quantum objects are not individuals. It seems clear that the RV finds its standard expression nowadays through the use of the formal apparatuses of non-reflexive logics, mainly quasi-set theory. In such logics, the relation of identity is restricted, so that it does not apply for terms denoting quantum particles; this “lack of identity” formally characterizes their non-individuality. We face then a dilemma: on the one hand, identity (...) seems too important to be given up, on the other hand the RV seems to require that identity be given up. In this paper we shall discuss how the specific characterization of the RV through non-reflexive logics came to be framed. We examine some of the main objections to this version of the RV and argue that they are misguided under this specific “non-reflexive” understanding of the RV. Finally, we shall also argue that this non-reflexive view is not the only option for a metaphysical articulation of the RV: less radical approaches to identity and logic are open. In particular, some of these alternative approaches to the RV we present may be immune to most of the criticisms presented against the non-reflexive approach. (shrink)

Can we change our logic and if so how? In ‘The Question of Logic’ (this volume), Saul Kripke takes a certain message about this from Lewis Carroll’s famous pape.

According to ‘Fitting Attitude’ (FA) analyses of value, for an object to be valuable is for that object to have properties—other than its being valuable—that make it a fitting object of certain responses. In short, if an object is positively valuable it is fitting to favour it; if an object is negatively valuable it is fitting to disfavour it. There are several variants of FA analyses. Some hold that for an object to be valuable is for it to be such (...) that it ought to be favoured; others hold that value is analyzable in terms of reasons or requirements to favour. All these variants of the FA analysis are subject to a partiality challenge : there are circumstances in which some agents have reasons to favour or disfavour some object—due to the personal relations in which they stand to the object—without this having any bearing on the value of the object. A. C. Ewing was one of the first philosophers to draw attention to the partiality challenge for FA analyses. In this paper I explain the challenge and consider Ewing's responses, one of which is preferable to the other, but none of which is entirely satisfactory. I go on to develop an alternative Brentano-inspired response that Ewing could have offered and that may well be preferable to the responses Ewing actually did offer. (shrink)

We discuss the idea that superpositions in quantum mechanics may involve contradictions or contradictory properties. A state of superposition such as the one comprised in the famous Schrödinger’s cat, for instance, is sometimes said to attribute contradictory properties to the cat: being dead and alive at the same time. If that were the case, we would be facing a revolution in logic and science, since we would have one of our greatest scientific achievements showing that real contradictions exist.We analyze that (...) claim by employing the traditional square of opposition.We suggest that it is difficult to make sense of the idea of contradiction in the case of quantum superpositions. From a metaphysical point of view the suggestion also faces obstacles, and we present some of them. (shrink)

Following J.-Y.Béziau in his pioneer work on non-standard interpretations of the traditional square of opposition, we have applied the abstract structure of the square to study the relation of opposition between states in superposition in orthodox quantum mechanics in [1]. Our conclusion was that such states are contraries, contradicting previous analyzes that have led to different results, such as those claiming that those states represent contradictory properties. In this chapter we bring the issue once again into the center of the (...) stage, but now discussing the metaphysical presuppositions which underlie each kind of analysis and which lead to each kind of result, discussing in particular the idea that superpositions represent potential contradictions. We shall argue that the analysis according to which states in superposition are contrary rather than contradictory is still more plausible. (shrink)

The recent MB case involved a dispute between an infant’s parents and his medical team about the appropriateness of continued life support. The dispute reflected uncertainty about two key factors that inform medical decision making for seriously ill infants: both the amount of pain MB experiences and the extent of his cognitive capacities are uncertain. Uncertainty of this order makes decision making in accordance with the best-interests principle very problematic. This article addresses two of the problems that cases such as (...) that of MB pose for those charged with making medical decisions for infants. First, the question of the moral significance of the interest in avoiding pain is considered. It is claimed that this interest can be outweighed by higher-order interests such as those related to autonomy but that where such higher-order interests do not exist, the interest in avoiding pain should be prioritised. Second, the question of how to proceed in cases in which the level of pain or the extent of an infant’s higher-order interests cannot be decisively established is considered. It is suggested that when genuine uncertainty over the interests of an infant exists, parental views about treatment should prevail.The English family courts recently adjudicated on another case involving conflict between parents and a medical team over the provision of life-prolonging medical treatment for an infant. At the time of the ruling, MB was an 18-month-old boy with type I spinal muscular atrophy. His life expectancy was very short , he was almost completely paralysed and he required constant ventilation. MB’s parents wanted a tracheotomy to be performed to facilitate long-term ventilation and allow for some independence from the hospital ward, but the …. (shrink)

We introduce a framework that allows for the construction of sequent systems for expressive description logics extending ALC. Our framework not only covers a wide array of common description logics, but also allows for sequent systems to be obtained for extensions of description logics with special formulae that we call "role relational axioms." All sequent systems are sound, complete, and possess favorable properties such as height-preserving admissibility of common structural rules and height-preserving invertibility of rules.

Quasi-set theory Q is an alternative set-theory designed to deal mathematically with collections of indistinguishable objects. The intended interpretation for those objects is the indistinguishable particles of non-relativistic quantum mechanics, under one specific interpretation of that theory. The notion of cardinal of a collection in Q is treated by the concept of quasi-cardinal, which in the usual formulations of the theory is introduced as a primitive symbol, since the usual means of cardinal definition fail for collections of indistinguishable objects. In (...) a recent work, Domenech and Holik have proposed a definition of quasi-cardinality in Q. They claimed their definition of quasi-cardinal not only avoids the introduction of that notion as a primitive one, but also that it may be seen as a first step in the search for a version of Q that allows for a greater representative power. According to them, some physical systems can not be represented in the usual formulations of the theory, when the quasi-cardinal is considered as primitive. In this paper, we discuss their proposal and aims, and also, it is presented a modification from their definition we believe is simpler and more general. (shrink)

In this paper we deal with two applications of the square of opposition to controversial issues in the philosophy of quantum mechanics. The first one concerns the kind of opposition represented by states in superposition. A superposition of “spin up” and “spin down” for a given spatial direction, for instance, is sometimes said to originate particular kinds of opposition such as contradictoriness. The second application concerns the problem of identical particles. Identity and indiscernibility are entangled in discussions of this problem (...) in such a way that a proper conceptual treatment of those issues through the square seems profitable. (shrink)

In this paper we propose to take seriously the claim that at least some kinds of paraconsistent negations are subcontrariety forming operators. We shall argue that from an intuitive point of view, by considering paraconsistent negations as formalizing that particular kind of opposition, one needs not worry with issues about the meaning of true contradictions and the like, given that “true contradictions” are not involved in these paraconsistent logics. Our strategy will consist in showing that, on the one hand, the (...) natural translation for subcontrariety in formal languages is not a contradiction in natural language, and on the other, translating alleged cases of contradiction in natural language to paraconsistent formal systems works only provided we transform them into a subcontrariety. Transforming contradictions into subcontrariety shall provide for an intuitive interpretation for paraconsistent negation, which we also discuss here. By putting all those pieces together, we hope a clearer sense of paraconsistency can be made, one which may liberate us from the need to tame contradictions. (shrink)

The purpose of the paper is to investigate into the philosophical concept of human embodiment in relation to physical education. As human beings we do not only have a body that we can control, but we ”are” our body and live embodied in the world, as the German thinker, Helmuth Plessner, puts it in one of his many contributions to the philosophical anthropology of the 20th century. Elaborating on this concept of human embodiment the paper explores a form of physical (...) re-education that takes as its starting point this aspect of being in the body which has been and is still being underestimated even in the physical educational system. Re-educating the body in this aspect includes becoming more aware of the states, postures and expressions of the body so as to be able to remain connected to the body and to get to know oneself better as being in the body.

ABSTRACTModern technological means allow for meaningful interaction across arbitrary distances, while human morality evolved in environments in which individuals needed to be spatially close in order to interact. We investigate how people integrate knowledge about modern technology with their ancestral moral dispositions to help relieve nearby suffering. Our first study establishes that spatial proximity between an agent's means of helping and the victims increases people's judgement of helping obligations, even if the agent is constantly far personally. We then report and (...) meta-analyse 20 experiments elucidating the cognitive mechanisms behind this effect, which include inferences of increased efficaciousness and personal involvement. Implications of our findings for the scientific understanding of ancestral moral dispositions in modern environments are discussed, as well as suggestions for how these insights might be exploited to increase charitable giving. Our meta-analysis provides a practical example.. (shrink)

This book answers both the 'what' and the 'why' question raised by indexical shift in crosslinguistic perspective. What are the possible profiles of an indexical shifting language, and why do we find these profiles and not various equally conceivable others? Drawing both from the literature (published and unpublished) and from original fieldwork on the language Nez Perce, Amy Rose Deal puts forward several major generalizations about indexical shift crosslinguistically and present a theory that attempts to explain them. This account (...) has consequences for the way we think about the semantics of attitude verbs, the nature of contexts, the typology of first person, and the relationship between indexicals and logophors, of course along with numerous consequences for the analysis of particular languages (e.g. Nez Perce, Uyghur, Korean, English, Zazaki, Amharic, Mishar Tatar). The book contains numerous glossed examples from a range of languages (including a detailed description of Nez Perce indexical shift, based on original fieldwork, as described above); a bibliography; and an appendix providing grammatical background about Nez Perce.

The last 20 years or so has seen an intense search carried out within Dempster–Shafer theory, with the aim of finding a generalization of the Shannon entropy for belief functions. In that time, there has also been much progress made in credal set theory—another generalization of the traditional Bayesian epistemic representation—albeit not in this particular area. In credal set theory, sets of probability functions are utilized to represent the epistemic state of rational agents instead of the single probability function of (...) traditional Bayesian theory. The Shannon entropy has been shown to uniquely capture certain highly intuitive properties of uncertainty, and can thus be considered a measure of that quantity. This article presents two measures developed with the purpose of generalizing the Shannon entropy for (1) unordered convex credal sets and (2) possibly non-convex credal sets ordered by second order probability, thereby providing uncertainty measures for such epistemic representations. There is also a comparison with the results of the measure AU developed within Dempster–Shafer theory in a few instances where unordered convex credal set theory and Dempster–Shafer theory overlap.

The “demos paradox” is the idea that the composition of a demos could never secure democratic legitimacy because the composition of a demos cannot itself be democratically decided. Those who view this problem as unsolvable argue that this insight allows them to adopt a critical perspective towards common ideas about who has legitimate standing to participate in democratic decision-making. We argue that the opposite is true and that endorsing the demos paradox actually undermines our ability to critically engage with common (...) ideas about legitimate standing. We challenge the conception of legitimacy that lurks behind the demos paradox and argue that the real impossibility is to endorse democracy without also being committed to significant procedure-independent standards for the legitimate composition of the demos. We show that trying to solve the problem of the demos by appeal to some normative conception of democratic legitimacy is a worthwhile project that is not undermined by paradox. (shrink)

Recent years have seen a renewed interest in the philosophical study of information. In this paper a two-part analysis of information gain—objective and subjective—in the context of doxastic change is presented and discussed. Objective information gain is analyzed in terms of doxastic movement towards true belief, while subjective information gain is analyzed as an agent’s expectation value of her objective information gain for a given doxastic change. The resulting expression for subjective information gain turns out to be a familiar one (...) with well-known formal properties: the Kullback–Leibler divergence. The two notions of information are discussed and the suggested measure of subjective information gain is then compared with the widely held view that information gain equals uncertainty reduction.

We first deal with a few preliminary matters and discuss what-if any-distinct impact belief in moral error theory should have on our moral practice. Second, we describe what is involved in giving an answer to our leading question and take notice of some factors that are relevant to what an adequate answer might look like. We also argue that the specific details of adequate answers to our leading question will depend largely on context. Third, we consider three extant answers to (...) our leading question: fictionalism, conservationism, and abolitionism. Of these three, conservationism seems most promising. However, conservationism leaves pertinent questions unanswered. In order to provide answers to these questions, and ultimately to provide an answer to our leading question, conservationism needs to be supplemented, yielding an account we call “negotiationism.” This final proposal is not neat and tidy, but it might work reasonably well in the moral environment in which error theorists are likely to find themselves.

This special issue aims to redress the balance and to open up Gaston Bachelard's work beyond a small in-crowd of experts and aficionado’s in France. It aims to stimulate the discovery of new and understudied aspects of Bachelard’s work, including aspects of the intellectual milieu he was working in. Fortunately, for this purpose we were able to rely both on renowned Bachelard specialists, such as Hans-Jörg Rheinberg-er, Cristina Chimisso and Dominique Lecourt, as well as on a number of younger scholars (...) who are discovering their work in a different intellectual context. At the same time we also want to reassess the value of this oeuvre, which also entails examining the reasons and causes of the relative neglect of Bachelard’s work in recent times. Has it exhausted its possibilities? Does it have intrinsic limitations that have contributed to the eclipse, as some influential, mainly French, philoso-phers have more or less explicitly suggested?

Among the results of this paper are the following: 1. Every Boolean power is the union of an updirected elementary family of direct ultrapowers. 2. Under certain conditions, a finitely iterated Boolean ultrapower is isomorphic to a single Boolean ultrapower. 3. A $\omega$-bounded filtral power is an elementary substructure of a filtral power. 4. Let $\mathscr{K}$ be an elementary class closed under updirected unions ; then $\mathscr{K}$ is closed under finite products if and only if $\mathscr{K}$ is closed under reduced (...) products if and only if $\mathscr{K}$ is a Horn class.

Quantum theory is perhaps our best confirmed theory for a description of the physical properties of nature. On top of demonstrating great empirical effectiveness, many technological developments in the 20th century (such as the interpretation of the periodic table of elements, CD players, holograms, and quantum state teleportation) were only made possible with Quantum theory.Despite its success in the past decades, even today it still remains without a universally accepted interpretation.This book provides an interdisciplinary perspective on the question; 'What is (...) Quantum Mechanics talking about?', a question which continues to be one of the most fascinating and important questions in science.Using an interdisciplinary approach to foundational problems in Quantum Mechanics (QM), ranging from philosophical questions about the interpretation of QM to technical problems in quantum computation, this book explores quantum mechanics from different perspectives (physical, logical, philosophical and mathematical), by researchers from Europe, North America, and South America.

A well-known trilemma faces the interpretation of Kant’s theory of affection, namely whether the objects that affect us are empirical, noumenal, or both. I argue that according to Kant, the things that affect us and cause representations in us are not empirical objects. I articulate what I call the Causal Power Argument, according to which empirical objects cannot affect us because they do not have the right kind of power to cause representations. All the causal powers that empirical objects have (...) are moving powers, and such powers can only have spatial effects. According to Kant, however, the representations that arise in us as a result of the affection of our sensibility are non-spatial. I show that this argument is put forward by Kant in a number of passages, and figures as a decisive reason for rejecting empirical affection and instead endorsing affection by the things in themselves.

In this paper, I argue that Friedrich Nietzsche’s concept of self-overcoming has been largely misinterpreted in the philosophy of education journals. The misinterpretation partially stems from a misconstruction of Nietzsche’s perspectivism, and leads to a conception of self-overcoming that is inconsistent with Nietzsche’s educational ideals. To show this, I examine some of the prominent features of the so-called “debate” of the 1980s surrounding Nietzsche’s conception of self-overcoming. I then offer an alternative conception that is more consistent with Nietzsche’s thought, and (...) provides a more nuanced understanding of Nietzsche’s “anti-democratic” pedagogy. Ultimately, I argue that while Nietzsche’s educational philosophy is not egalitarian, it can be effectively utilized in “democratic” classrooms, assuming his concept of self-overcoming is properly construed.

In this paper a bootstrap theory of rationality is presented. Such a theory is an attempt to explain how standards of rational inquiry may be rationally revised — without assuming that there are any basic and fixed standards for evaluating such revisions. The general bootstrap idea is briefly presented in the first sections. The main part of the paper consists of a discussion of what normative requirements a bootstrap theory should contain, and a number of requirements on rational revisions are (...) proposed. The final section deals with the question of whether a bootstrap theory is self-referentially coherent. (shrink)

A central aim for philosophers of science has been to understand scientific theory change, or more specifically the rationality of theory change. Philosophers and historians of science have suggested that not only theories but also scientific methods and standards of rational inquiry have changed through the history of science. The topic here is methodological change, and what kind of theory of rational methodological change is appropriate. The modest ambition of this paper is to discuss in what ways results in formal (...) theories of belief revision can throw light on the question of what an appropriate theory of methodological change would look like.

Making interactions between humans and artificial agents successful is a major goal of interaction design. The aim of this paper is to provide researchers conducting interaction studies a new framework for the evaluation of robot believability. By critically examining the ordinary sense of believability, we first argue that currently available notions of it are underspecified for rigorous application in an experimental setting. We then define four concepts that capture different senses of believability, each of which connects directly to an empirical (...) methodology. Finally, we show how this framework has been and can be used in the construction of interaction studies by applying it to our own work in human–robot interaction. (shrink)

“Everything finite we can doubt, but not the Infinite,” so wrote Josiah Royce in his first major philosophical work, The Religious Aspect of Philosophy. He has not made many converts to his position. Even those who are sympathetic to his philosophy do, as a rule, display “uncertainty about his conclusions, if not outright rejection,” as Roth, the most recent editor of Royce’s works, observes. Such misgivings are to be traced to the prevailing opinion that Royce’s demonstration of the existence of (...) God rests on his analysis of the nature of error; and it cannot be denied that here, as McDermott, another editor of Royce’s works remarks, Royce seems to be guilty of failing to “distinguish adequately between the Infinite as an all-inclusive system of thought and the Infinite as personal, responsive to a plurality of other persons.” Serious doubts, however, can be raised as to the validity of interpreting Royce’s proof for the existence of God in terms of his analysis of error. To begin with, there is a question of what we are to make out of all those pages—three hundred and eighty-three altogether—preceding that analysis. Have they nothing to do with the proof? Then, too, what is the meaning of Royce’s repeated admonition that thoroughgoing doubt and despair constitute the very core of a philosophic experience? Now whatever else we may think of the analysis of error, it certainly is not of the kind that arouses despair in us. It appears then that there is something radically wrong in maintaining that in The Religious Aspect of Philosophy Royce bases his proof of the existence of God on the analysis of error. I suggest that a much more rewarding interpretation of Royce’s proof is to be gained if we are willing to seek it in the pages preceding the analysis of error and if we view the analysis itself as more of an addendum to the proof rather than as proof itself. The purpose of this essay is to show that such an interpretation is well-justified. (shrink)
