Armstrong’s combinatorial theory of possibility faces the obvious difficulty that not all universals are compatible. In this paper I develop three objections against Armstrong’s attempt to account for property incompatibilities. First, Armstrong’s account cannot handle incompatibilities holding among properties that are either simple, or that are complex but stand to one another in the relation of overlap rather than in the part/ whole relation. Secondly, at the heart of Armstrong’s account lies a notion of structural universals which, building (...) on an objection by David Lewis, is shown to be incoherent. I consider and reject two alternative ways of construing the composition of structural universals in an attempt to meet Lewis’ objection. An important consequence of this is that all putative structural properties are in fact simple. Finally, I argue that the quasi-mereological account presupposes modality in a way that undermines the reductionist aim of the combinatorialist theory of which it is a central part. I conclude that Armstrong’ quasi-mereological account of property incompatibility fails. Without that account, however, Armstrong’s combinatorial theory either fails to get off the ground, or else must give up its goal of reducing the notion of possibility to something non-modal.

In this paper we extend Wittgenstein’s notion of family resemblance to translation, interpretation, and comparison across traditions. There is no need for universals. This holds for everyday concepts such as green and qing 青, philosophical concepts such as emotion and qing 情, as well as philosophical categories such as form of life and dao 道. These notions as well as all other concepts from whatever tradition are family resemblance concepts. We introduce the notion of quasi-universal, which connects family (...) resemblance concepts from a limited number of traditions. The possibility and necessity of extending family resemblance concepts across traditions dissolves the false antinomy of universalism versus relativism. (shrink)

Laws in the special sciences are usually regarded to be non-universal. A theory of laws in the special sciences faces two challenges. (I) According to Lange's dilemma, laws in the special sciences are either false or trivially true. (II) They have to meet the ?requirement of relevance?, which is a way to require the non-accidentality of special science laws. I argue that both challenges can be met if one distinguishes four dimensions of (non-) universality. The upshot is that I argue (...) for the following explication of special science laws: L is a special science law just if (1) L is a system law, (2) L is quasi-Newtonian, and (3) L is minimally invariant.

We apply the theory of partial algebras, following the approach developed by Van Alten, to the study of the computational complexity of universal theories of monotonic and normal modal algebras. We show how the theory of partial algebras can be deployed to obtain co-NP and EXPTIME upper bounds for the universal theories of, respectively, monotonic and normal modal algebras. We also obtain the corresponding lower bounds, which means that the universal theory of monotonic modal algebras is co-NP-complete and the universal (...) theory of normal modal algebras is EXPTIME-complete. It also follows that the quasi-equational theory of monotonic modal algebras is co-NP-complete. While the EXPTIME upper bound for the universal theory of normal modal algebras can be obtained in a more straightforward way, as discussed in the paper, due to its close connection to the equational theory of normal modal algebras with the universal modality operator, the technique based on the theory of partial algebras is applicable to the study of universal theories of algebras corresponding to a wide range of logics with intensional operators, where no such connection is available.

Universality has been an important concept in computable structure theory. A class C of structures is universal if, informally, for any structure of any kind there is a structure in C with the same computability-theoretic properties as the given structure. Many classes such as graphs, groups, and fields are known to be universal. This paper is about the class of finitely generated groups. Because finitely generated structures are relatively simple, the class of finitely generated groups has no hope of being (...) universal. We show that finitely generated groups are as universal as possible, given that they are finitely generated: for every finitely generated structure, there is a finitely generated group which has the same computability-theoretic properties. The same is not true for finitely generated fields. We apply the results of this investigation to quasi Scott sentences, and also answer a question of Alvir, Knight, and McCoy. (shrink)

We describe which subdirectly irreducible flat algebras arise in the variety generated by an arbitrary class of flat algebras with absorbing bottom element. This is used to give an elementary translation of the universal Horn logic of algebras, and more generally still, partial structures into the equational logic of conventional algebras. A number of examples and corollaries follow. For example, the problem of deciding which finite algebras of some fixed type have a finite basis for their quasi-identities is shown (...) to be equivalent to the finite identity basis problem for the finite members of a finitely based variety with definable principal congruences.

The author has recently proposed a “quasi-classical” theory of particles and interactions in which particles are pictured as extended periodic disturbances in a universal field χ(x, t), interacting with each other via nonlinearity in the equation of motion for χ. The present paper explores the relationship of this theory to nonrelativistic quantum mechanics; as a first step, it is shown how it is possible to construct from χ a configuration-space wave function Ψ(x 1,x 2,t), and that the theory requires (...) that Ψ satisfy the two-particle Schrödinger equation in the case where the two particles are well separated from each other. This suggests that the multiparticle Schrödinger equation can be obtained as a direct consequence of the quasi-classical theory without any use of the usual formalism (Hilbert space, quantization rules, etc.) of conventional quantum theory and in particular without using the classical canonical treatment of a system as a “crutch” theory which has subsequently to be “quantized.” The quasi-classical theory also suggests the existence of a preferred “absolute” gauge for the electromagnetic potentials.

Olivier Tinland | : Dans cet article, je me propose de clarifier la manière dont Jürgen Habermas utilise le terme « quasi-transcendantal » dans l’ensemble de son oeuvre. Examinant successivement le projet épistémologique de Connaissance et intérêt, l’élaboration de l’« éthique de la discussion » et le « tournant pragmatiste » des dernières oeuvres, j’entends montrer que Habermas, loin d’abandonner une telle manière ambiguë de réactualiser le projet kantien, a tenté, tout au long de son évolution philosophique, de trouver (...) une formulation cohérente de la tension entre la contingence empirique des contextes sociaux de la vie humaine et la nécessité contrefactuelle des prétentions universelles à la vérité et à la validité normative. | : In this paper, I intend to clarify the way Jürgen Habermas uses the term “quasi-transcendental” throughout his whole work. Starting from the epistemological project of Knowledge and Interest, going on with the elaboration of the “ethics of discussion”, ending with the “pragmatist turn” of the late works, I want to show that Habermas, far from abandoning such an ambiguous way of updating the Kantian project, has tried, all along his philosophical development, to find a consistent formulation of the tension between the empirical contingency of social contexts of human life and the counterfactual necessity of universal claims about truth and normative validity.

In this paper, I develop a quasi-transcendental argument to justify Kant’s infamous claim “man is evil by nature.” The cornerstone of my reconstruction lies in drawing a systematic distinction between the seemingly identical concepts of “evil disposition” (böseGesinnung) and “propensity to evil” (Hang zumBösen). The former, I argue, Kant reserves to describe the fundamental moral outlook of a single individual; the latter, the moral orientation of the whole species. Moreover, the appellative “evil” ranges over two different types of moral (...) failure: while an “evil disposition” is a failure to realize the good (i.e., to adopt the motive of duty as limiting condition for all one’s desires), an “evil propensity” is a failure to realize the highest good (i.e., to engage in the collective project of transforming the legal order into an ethical community). This correlation between units of moral analysis and types of obligation suggests a way to offer a deduction of the universal propensity on behalf of Kant. It consists in tracing the source of radical evil to the same subjective necessity that gives rise to the doctrine of the highest good. For, at the basis of Kant’s two doctrines lies the same natural dialectic between happiness and morality. While the highest good brings about the critically acceptable resolution of this dialectic, the propensity to evil perpetuates and aggravates it. Instead of connecting happiness and morality in an objective relation, the human will subordinatesmorality to the pursuit of happiness according to the subjective order of association. If this reading is correct, it would explain why prior attempts at a transcendental deduction have failed: interpreters have looked for the key to the deduction in the body of Kant’s text, where it is not to be found, for it is tucked, instead, in the Preface to the first edition.

The debate on the a fortiori and the universal that took place between April 1914 and April 1919 in the journal Mind has a double interest for argumentation theorists. First, the discussion is an example of a philosophical polylogue that exhibits the characteristics of a quasi-engaged dialogue (Blair Blair, J. A. (2012 [1998]). “The Limits of the Dialogue Model of Argument”. Argumentation 12, pp. 325–339. Reprinted in J.A. Blair, Groundwork in the Theory of Argumentation, pp. 231–244. Dordrecht: Springer, 2012.), (...) confirming Blair’s hypothesis that journal papers and scholarly monographs can be analyzed as turns in non-engaged or quasi-engaged dialogues. It could be said that philosophical argumentation is dialectical but not dialogical. Second, the debate is a discussion in argumentation theory. Generalism in the theory of argument claims that the very possibility of arguing depends on a suitable supply of general rules that specify what kinds of conclusions can be drawn from what kinds of data, while particularism denies this. Although the terminology may be alien, I will also show that the debate on the a fortiori and the universal was a debate on generalism and particularism. (shrink)

Many studies focused on the letter and sound co-occurrences to account for the well-documented syllable-based effects in French in visual (pseudo)word processing. Although these language-specific statistical properties are crucial, recent data suggest that studies which go all-in on phonological and orthographic regularities may be misguided in interpreting how – and why – readers locate syllable boundaries and segment clusters. Indeed, syllable-based effects could depend on more abstract, universal phonological constraints that rule and govern how letter and sound occur and co-occur, (...) and readers could be sensitive to sonority – a universal phonological element – for processing (pseudo)words. Here, we investigate whether French adult skilled readers rely on universal phonological sonority-related markedness continuum across the syllable boundaries for segmentation (e.g., from marked, illegal intervocalic clusters /zl/ to unmarked, legal intervocalic clusters /lz/). To address this question, we ran two tasks with 128 French adult skilled readers using two versions of the illusory conjunction paradigm (Task 1 without white noise; Task 2 with white noise). Our results show that syllable location and segmentation in reading is early and automatically modulated by phonological sonority-related markedness in the absence or quasi-absence of statistical information, and does not require acoustic-phonetic information. We discuss our results towards the overlooked role of phonological universals and the over-trusted role of statistical information during reading processes. (shrink)

The essay adopts the Tractarian view that configurations of objects are expressed by configurations of names. Two alternatives are considered: The objects in atomic facts are (1) without exception particulars; (2) one or more particulars plus a universal (Gustav Bergmann). On (1) a mode of configuration is always an empirical relation: on (2) it is the logical nexus of 'exemplification.' It is argued that (1) is both Wittgenstein's view in the Tractatus and correct. It is also argued that exemplification is (...) a 'quasi-semantical' relation, and that it (and universals) are "in the world" only in that broad sense in which the 'world' includes linguistic norms and roles viewed (thus in translating) from the standpoint of a fellow participant.

Under the tutelage of Barthes, Derrida, and Foucault, literary critics learned to speak of authors, characters, settings, and plots not as individuals situated in a natural world but as discursive formations constituted by the circulation of linguistic, cultural, and ideological energies. In the three decades during which poststructuralism has dominated academic literary study, a different kind of revolution—evolutionary, Darwinian, and naturalistic—has been transforming the social sciences. Sociobiology, evolutionary psychology, Darwinian anthropology, behavioral ecology, cognitive archaeology, and behavioral genetics do not all agree with one another in every respect, but they are all nonetheless aspects or phases of a common research program. The central working hypothesis in this program is that the human species, like all other species, has evolved in an adaptive relation to its environment and that as a consequence it has a distinct, genetically transmitted, species-typical set of characteristics—anatomical, physiological, hormonal, neurological, and behavioral. That set of characteristics is what in common language is meant by "human nature." Literature has always given us subjectively evocative depictions of human nature, and Darwinian social science is now giving us a more comprehensive and scientifically precise account of it. The sense of [End Page 286] individual agency is one crucial aspect of human nature, and that aspect is now being explored in complementary ways by personality psychology and by cognitive neuroscience.1Over the past decade or so, a scattered handful of literary scholars has broken away from the dominant poststructuralist paradigm and has sought to make use of the new scientific information on human nature.2 The simplest and most obvious way to use this information is to examine the behavior depicted in literary texts and to correlate that behavior with "human universals," that is, with forms of behavior that appear in every known culture and that thus appear to be embedded in the nature of the species. Seeking depictions of universals has produced valuable results for literary study, but this first move in Darwinian criticism does not exhaust the range of possibility in the analysis of literary meaning. Human nature is complex and sometimes divided against itself; individuals vary, and some variations depart from species-typical patterns, even in the most adaptively crucial aspects of survival and reproduction. Moreover, literary meaning involves more than the represented subject matter. Authors imbue texts with meanings and affects peculiar to themselves; authors engage in communicative transactions with audiences; and texts have formal and aesthetic properties that are not reducible to represented subject matter. All of these aspects of the total literary situation are part of literary meaning, and all of them can and should fall within the range of analysis available to Darwinian literary study.3Oscar Wilde's The Picture of Dorian Gray offers two special challenges to Darwinian criticism. First, the novel is saturated with homoerotic sexual feeling, and it thus defies any simple reading in terms of behavior oriented to reproductive success. Second, the central conflicts in the novel involve two competing visions of human nature, and in their conceptual structure neither of those visions corresponds very closely to the quasi-Darwinian conceptual structure implicit in most realist and naturalist fiction. One vision derives from the aestheticist doctrines of Walter Pater, and the other from a traditional Christian conception of the soul. Pater's ideas about human motives and the human moral character are at variance both with Christianity and with Darwinism. Christianity and Darwinism share certain concepts of the human moral and social character, but they couch those concepts in different idioms, and they would invoke wholly different causal explanations for how human nature came to be the way it is. Wilde does not develop his themes in Darwinian terms, but the novel can still be read [End Page... (shrink)

One common feature of debates about the best metaphysical analysis of putatively lawful phenomena is the suspicion that nomic realists who locate the modal force of such phenomena in quasi-causal necessitation relations between universals are working with a model of law that cannot convincingly erase its theological pedigree. Nancy Cartwright distills this criticism into slogan form: no God, no laws. Some have argued that a more plausible alternative for nomic realists who reject theism is to ground laws of (...) nature in the fundamental dispositional properties or “pure powers” of physical objects. This article argues that for all its advantages over deflationary and rival realist accounts, a pandispositionalist account of law cuts against the commitment to metaphysical naturalism that its supporters almost always presuppose. It then examines and rejects a Platonic version of this account before elaborating and advancing a theistic alternative that is more theoretically powerful and more metatheoretically parsimonious. In slogan form: no God, no powers. (shrink)

Aquinas’s process of abstraction of the particular thing into a universal concept is of pivotal importance for grounding his philosophy and theology in a natural framework. Much has been said and written regarding Aquinas’s doctrine of abstraction, yet recent studies still consider it to be ‘nothing more than a kind of magic.’ This problematic claim is not without foundation, for in trying to understand exactly how this process works, we are constantly faced with an unbridgeable abyss and the repeated vague (...) explanations made by Aquinas. The plain truth is that Aquinas explains what abstraction ought to do and yet, most of the time, he does not explain how it is to be done. This paper intends to show that although Aquinas does not present us with a mechanism for the theory of abstraction, we are nevertheless able to construct a viable mechanism which accords with Aquinas’s guidelines. The aim of constructing a working mechanism that corresponds to what Aquinas demands of the process of abstraction is twofold: First, it attempts to extricate Aquinas’s doctrine of abstraction from the claims of being a quasi-natural doctrine. Second, a viable process of abstraction which is derived from Aquinian-Aristotelian sources can approach contemporary cognitive problems from a fresh point of view. (shrink)

Aquinas famously argues that there exists a purely active intellective power—i.e., the agent intellect—in each human agent that is capable of “abstracting” universals, including natures, from sensible phantasms. Robert Pasnau has worried, however, that Aquinas’s thin account of how the agent intellect performs abstraction makes abstraction appear to be little short of “magic.” In this paper I reply to Pasnau’s objection by arguing for the necessity of expanding the standard account of Aquinas’s theory to include the oft-neglected role of (...) the so-called “interior sense powers,” in particular memory and the cogitative power, in his epistemology. I argue that for Aquinas memory and the cogitative power, operat­ing in close cooperation with intellect, are responsible for bridging the ontological and epistemological divide between sensation of the singular and intellection of the universal by producing the pre-intellective, quasi-knowledge of experience (experimentum), which is propaedeutic to abstraction.

v. 1. Nominalism and realism.--v. 2. A theory of universals.

In this short text, a distinguished philosopher turns his attention to one of the oldest and most fundamental philosophical problems of all: How it is that we are able to sort and classify different things as being of the same natural class? Professor Armstrong carefully sets out six major theories—ancient, modern, and contemporary—and assesses the strengths and weaknesses of each. Recognizing that there are no final victories or defeats in metaphysics, Armstrong nonetheless defends a traditional account of universals as (...) the most satisfactory theory we have.This study is written for advanced students, but as Armstrong goes considerably beyond his earlier work on this topic, it will interest professional scholars as well. Carefully plotted and clearly written, Universals is both a paradigm of exposition and a case study on the value of careful analysis of fundamental issues in philosophy. (shrink)

While opinions on the semantic analysis of generics vary widely, most scholars agree that generics have a quasi-universal flavor. However, there are cases where generics receive what appears to be an existentialinterpretation. For example, B's response is true, even though only theplatypus and the echidna lay eggs: (1) A: Birds lay eggs. B: Mammals lay eggs too. In this paper I propose a uniform account of the semantics of generics,which accounts for their quasi-existential readings as well as for (...) their more familiar quasi-universal ones. Generics are focus-sensitiveoperators: their domain is restricted by a set of alternatives, which may be provided by focus. I claim that, unlike otherfocus-sensitive operators, generics may, but do not have to, associate with focus. When alternatives are introduced, either by focus or by other means, generics get their usual quasi-universal readings. But when no alternatives are introduced, quasi-existential readings result.I argue that generics, unlike adverbs of quantification, do not introduce tripartite structures directly, but are initially interpreted as cases ofdirect kind predication. Only when this interpretation fails to make sense, the phonologically null generic quantifier is derived, and tripartite structures result. This two-level interpretation has the effect that while adverbs of quantification require focus to determine which elements go to the restrictor and which to the nuclear scope, and hence must associate with focus, generics do not, and hence may fail to associate with focus, resulting in quasi-existential readings.

In a recent article, Azzouni has argued in favor of a version of formalism according to which ordinary mathematical proofs indicate mechanically checkable derivations.

Many policies and ethical guidelines recommend developing “trustworthy AI”. We argue that developing morally trustworthy AI is not only unethical, as it promotes trust in an entity that cannot be trustworthy, but it is also unnecessary for optimal calibration. Instead, we show that reliability, exclusive of moral trust, entails the appropriate normative constraints that enable optimal calibration and mitigate the vulnerability that arises in high-stakes hybrid decision-making environments, without also demanding, as moral trust would, the anthropomorphization of AI and thus (...) epistemically dubious behavior. The normative demands of reliability for inter-agential action are argued to be met by an analogue to procedural metacognitive competence (i.e., the ability to evaluate the quality of one’s own informational states to regulate subsequent action). Drawing on recent empirical findings that suggest providing reliability scores (e.g., F1-scores) to human decision-makers improves calibration in the AI system, we argue that reliability scores provide a good index of competence and enable humans to determine how much they wish to rely on the system.

In this volume, John Bacon argues that it is difficult to deny the existence of particularized properties and relations, which in modern philosophy are sometimes called `tropes'. In so doing, he advances a powerful and sophisticated metaphysical theory according to which both ordinary particulars and properties and relations are bundles of tropes.

In this paper, I discuss the distribution and interpretation of free choice items (FCIs) in Greek, a language exhibiting a lexical paradigm of such items distinct from that of negative polarity items. Greek differs in this respect from English, which uniformly employs any. FCIs are grammatical only in certain contexts that can be characterized as nonveridical (Giannakidou 1998, 1999), and although they yield universal-like interpretations in certain structures, they are not, I argue, universal quantifiers. Evidence will be provided that FCIsare (...) indefinites; the quasi-universal effect is shown to be the result of binding by an operator with universal force. Additionally, the limited distribution of FCIs in non veridical contexts can be accounted for by analyzing them as indefinites which must always be interpreted in an intensional type. The difference between ``regular'' indefinites and FCIs, therefore, is reduced to a type difference which captures the fact that only the latter exhibit limited distribution: because of their intensional type, FCIs will be grammatical only in contexts providing alternatives (worlds or situations), and nonveridical contexts do exactly this. By contrast, FCIs are excluded from veridical and episodic contexts because these provide no alternatives and hence do not satisfy the lexical semantic requirement ofFCIs. The proposed analysis is supported by data from other languages as well (Spanish, Catalan,French) and has important consequences regarding the analysis of English any. If FCIs are not universal quantifiers but indefinites, then the usual ambiguity thesis (free choice any being universal, negative polarity any an existential) can no longer be maintained, at least not as one in terms of quantificational force.

The objective of this thesis – Reflective Equilibrium as a Form of Life – is to contribute to the deepening of understanding of the method of reflective equilibrium – a method of internal epistemic justification. In the first part of the study, four paradigmatic conceptions of the method will be analyzed in order to carve out a conceptual core: The ones by John Rawls – who coined the name of the method – Norman Daniels, Michael DePaul and Catherine Elgin. I (...) will argue that the conceptual core of the method contains four elementary rules: 1) A minimalistic fallibilism, 2) a moderate holism, 3) a minimalistic rationality, and 4) a weak foundationalism. Compliance with these rules is necessary and jointly sufficient for any epistemic procedure of justification to be in accordance with the method of reflective equilibrium. The second part of the study is intended to answer some of the open questions concerning this definition of the conceptual core of the method. It will be argued that the a minimalistic fallibilism, as a very central element of the method, is justified since there is no belief whose truth is transparent to an epistemic agent. Even if it were the case that such beliefs exist, there would be attractive options of retreat which provide a quasi-universal justification of minimalistic fallibilism. It will also be argued that all alternative methods of justification are either compatible with the method of reflective equilibrium or are not justified. While a metajustification of the method – understood as a justification of the method employing the method itself – is on the one hand not completely satisfactory, as it presupposes the acceptance of the method before it is justified, it is epistemically acceptable on the other hand, since it allows for a critical inquiry and is open-ended. It will be pointed out that a moderate foundationalism can be justified by the method for some specific area of inquiry insofar as basic beliefs can be identified. Yet, the default-position of the method is only a weak foundationalism (often also termed “coherentism”). With regard to the possibility of a formal interpretation of the method with which one could specify key terms used in the definition of the conceptual core, I will sketch general ways such a formalization might take. However, I will argue that the informal interpretation of the method has priority over any formal interpretation. In the third and concluding part of the study, I will present the claim that one should interpret the method of reflective equilibrium as a form of life. This means that the method is at least implicitly accepted by some epistemic agents: they have developed a disposition and ability to act according to the method. This interpretation of the method can be related to the notion of critical thinking, which, as a civic virtue and educational ideal, is subject of empirical research and practical application. A possible misunderstanding with respect to the method of reflective equilibrium as a form of life should be avoided: To interpret the method as a form of life does not indicate that it must be a comprehensive form of life. Acknowledging it in private life is optional. According to the proposed understanding of the method it is primarily a public and political form of life. (shrink)

Mathematicians do not claim to know a proposition unless they think they possess a proof of it. For all their confidence in the truth of a proposition with weighty non-deductive support, they maintain that, strictly speaking, the proposition remains unknown until such time as someone has proved it. This article challenges this conception of knowledge, which is quasi-universal within mathematics. We present four arguments to the effect that non-deductive evidence can yield knowledge of a mathematical proposition. We also show (...) that some of what mathematicians take to be deductive knowledge is in fact non-deductive. 1 Introduction2 Why It Might Matter3 Two Further Examples and Preliminaries4 An Exclusive Epistemic Virtue of Proof?5 Analyses of Knowledge6 The Inductive Basis of Deduction7 Physical to Mathematical Linkages8 Conclusion.

Plural definite descriptions across many languages display two well-known properties. First, they can give rise to so-called non-maximal readings, in the sense that they ‘allow for exceptions’. Second, while they tend to have a quasi-universal quantificational force in affirmative sentences, they tend to be interpreted existentially in the scope of negation. Building on previous works, we offer a theory in which sentences containing plural definite expressions trigger a family of possible interpretations, and where general principles of language use account (...) for their interpretation in various contexts and syntactic environments. Our theory solves a number of problems that these previous works encounter, and has broader empirical coverage in that it offers a precise analysis for sentences that display complex interactions between plural definites, quantifiers and bound variables, as well as for cases involving non-distributive predicates. The resulting proposal is briefly compared with an alternative proposal by Križ, which has similar coverage but is based on a very different architecture and sometimes makes subtly different predictions.

Quasi-realists aim to account for many of the trappings of metanormative realism within an expressivist framework. Chief among these is the realist way of responding to the Euthyphro dilemma: quasi-realists want to join realists in being able to say, "It’s not the case that kicking dogs is wrong because we disapprove of it. Rather, we disapprove of kicking dogs because it’s wrong." However, the standard quasi-realist way of explaining what we are up to when we assert the (...) first of these two sentences rests on a mistaken identification of metaphysical dependence (or grounding) with counterfactual covariation. This chapter proposes a better way for expressivists to understand such sentences, on which they serve to express complex states of mind in which an attitude bears a relation of psychological dependence (or basing) to another state of mind. It is argued that this proposal is a natural, versatile, and fruitful approach for expressivists to take that helps them secure the first half of the Euthyphro contrast—but at the cost of making it difficult to see how expressivists can make sense of that contrast’s second half.

The close ties between law and psychiatric illness challenge our effort to understand the complex semantics of Western culture and the foundations of law in the heart of that culture. It is, however, difficult to be immediately confronted with the limitations of these semantics. Can one ever achieve a refined precision of psychiatric issues? Lawyers and psychiatrists tend to disregard the fact that people live within different realms of expressiveness, even where the same phenomena seem apparent. They neutralize all relativity (...) and design a quasi-universal body of legal doctrines or construct an all-embracing medical nosology. The question remains what practices of judgment are justifiable when the history books demonstrate the ever-changing character of the idea of a common good and a well-ordered life. Notions of relativity accompany decisions to punish or to cure, to exclude or to include, to disregard or to consider. In these decisions, there are never supracultural notions at hand and only rarely ideas that reach beyond the boundaries of either profession's own discourse. (shrink)

In this essay, I draw out some implications of a position called “Wittgensteinian Quasi-Fideism” for the theory and practice of interreligious communication. After setting out the main tenets of that position, I articulate what its theoretical and practical implications in this area would be if it were true. I thereby sketch a new, Wittgensteinian model of interreligious communication, concluding with a number of suggestions as to some points of focus for further work in this area.

Quasi-fideism accounts for the rationality of religious belief by embracing the idea that a subject’s most fundamental religious commitments are essentially arational. It departs from standard forms of fideism, however, by contending that this feature of religious commitment does not set it apart from belief in general. Indeed, the quasi-fideist maintains, in keeping with the Wittgensteinian hinge epistemology that underlies the view, that it is in the nature of belief in general (i.e. religious or otherwise) that it presupposes (...) essentially arational commitments, and hence that there can be no specific epistemic objection to religious belief due to it having this feature. This paper explores how quasi-fideism deals with the problems raised by fundamental religious disagreement. In particular, how is quasi-fideism to avoid the charge of epistemic relativism? It is argued that once we understand the arational nature of these fundamental commitments correctly, then quasi-fideism is able to avoid a problematic form of epistemic relativism. Relatedly, it can also explain how a subject’s basic religious commitments can change over time in rational ways. (shrink)

Generic sentences involving phrasal conjunctions present a prima facie problem for the standard theory of generics according to which they express quasi-universal generalisations about what is characteristic for members of a particular kind. For example, the sentence ‘Elephants live in Africa and Asia’ is true, even though it is uncharacteristic for an elephant to live in both Africa and Asia. In response to this problem, theorists have recently proposed radical departures from the standard view. This paper argues that such (...) departures are unwarranted: not only do they fail to fully accommodate the data involving generic conjunctions, their scope is overly narrow, since the phenomena in question also arise in non-generic contexts. I propose a new theory of generics that aims to account for generic conjunctions in a principled manner and which sheds new light on the mereological commitments of natural language. (shrink)

In this paper, I argue that there are universals. I begin (Sect. 1) by proposing a sufficient condition for a thing’s being a universal. I then argue (Sect. 2) that some truths exist necessarily. Finally, I argue (Sects. 3 and 4) that these truths are structured entities having constituents that meet the proposed sufficient condition for being universals.

The aim of Intercultural Information Ethics (IIE), as Ess aptly puts, is to “(a) address both local and global issues evoked by ICTs / CMC, etc., (b) in a ways that both sustain local traditions / values / preference, etc. and (c) provide shared, (quasi-) universal responses to central ethical problems” (Ess 2007a, 102). This formulation of the aim of IIE, however, is not unambiguous. In this paper, I will discuss two different understandings of the aim of IIE, one (...) of which advocates “shared norms, different interpretations” and another proposes “shared norms, different justifications”. I shall argue that the first understanding is untenable, and the second understanding is acceptable only with qualification. Finally, I shall briefly suggest an alternative way to understand the aim of IIE. (shrink)

Language is a spontaneously evolved emergent adaptation, not a formal computational system. Its structure does not derive from either innate or social instruction but rather self-organization and selection. Its quasi-universal features emerge from the interactions among semiotic constraints, neural processing limitations, and social transmission dynamics. The neurological processing of sentence structure is more analogous to embryonic differentiation than to algorithmic computation. The biological basis of this unprecedented adaptation is not located in some unique neurologieal structure nor the result of (...) any single mutation, but is vested in the synergistic interaction of numerous coevolved neurological biases and social dynamics.
