According to Russell, the notation in Principia Mathematica has been designed to avoid the vagueness endemic to our natural language. But what does Russell think vagueness is? My argument is an attempt to show that his views on vagueness evolved and that the final conception he adopts is not coherent. Three phases of his conception of vagueness are identified, the most significant being the view that he articulates on vagueness in his 1923 address to the Jowett Society. My central thesis (...) is that the 1912 conception of vagueness -- what I characterize as "semantic egalitarianism" -- seriously conflicts with the later paradoxical account of vagueness. (shrink)

There are two intuitions about time. The first is that there's something special about the present that objectively differentiates it from the past and the future. Call this intuition Specialness. The second is that the time at which we happen to live is just one among many other times, all of which are ‘on a par’ when it comes to their forming part of reality. Call this other intuition Egalitarianism. Tradition has it that the so-called ‘A-theories of time’ fare (...) well at addressing the first intuition, but rather badly when it comes to the second. The goal of this article is to offer advice to A-theorists about how to reconcile their view with Egalitarianism. (shrink)

Luck egalitarianism is a family of egalitarian theories of distributive justice that aim to counteract the distributive effects of luck. This article explains luck egalitarianism's main ideas, and the debates that have accompanied its rise to prominence. There are two main parts to the discussion. The first part sets out three key moves in the influential early statements of Dworkin, Arneson, and Cohen: the brute luck/option luck distinction, the specification of brute luck in everyday or theoretical terms and (...) the specification of advantage as resources, welfare, or some combination of these. The second part covers three later developments: the democratic egalitarian critique of luck egalitarianism, the luck egalitarian acceptance of pluralism, and luck egalitarian doubts about the significance of the brute luck/option luck distinction.

A number of philosophers working in applied ethics and bioethics are now earnestly debating the ethics of what they term “moral bioenhancement.” I argue that the society-wide program of biological manipulations required to achieve the purported goals of moral bioenhancement would necessarily implicate the state in a controversial moral perfectionism. Moreover, the prospect of being able to reliably identify some people as, by biological constitution, significantly and consistently more moral than others would seem to pose a profound challenge to egalitarian (...) social and political ideals. Even if moral bioenhancement should ultimately prove to be impossible, there is a chance that a bogus science of bioenhancement would lead to arbitrary inequalities in access to political power or facilitate the unjust rule of authoritarians; in the meantime, the debate about the ethics of moral bioenhancement risks reinvigorating dangerous ideas about the extent of natural inequality in the possession of the moral faculties.

This paper argues that there are good reasons to limit the scope of luck egalitarianism to co‐existing people. First, I outline reasons to be sceptical about how “luck” works intergenerationally and therefore the very grounding of luck egalitarianism between non‐overlapping generations. Second, I argue that what Kasper Lippert‐Rasmussen calls the “core luck egalitarian claim” allows significant intergenerational inequality which is a problem for those who object to such inequality. Third, luck egalitarianism cannot accommodate the intuition that it (...) might be required to leave future generations better off than we are, even if it would come at no cost to ourselves. Finally, I argue that following another, broader, version of luck egalitarianism would require us to level down future generations and possibly even ourselves, which is a problem for those persuaded by the levelling‐down objection.

A survey of recent work on egalitarianism.

Calum Miller recently argued that a commitment to a very modest form of egalitarianism—equality between non-disabled human adults—implies fetal personhood. Miller claims that the most plausible basis for human equality is in being human—an attribute which fetuses have—therefore, abortion is likely to be morally wrong. In this paper, I offer a plausible defence for the view that equality between non-disabled human adults does not imply fetal personhood. I also offer a challenge for Miller’s view.

People’s health is hugely affected by where they live, their occupational status and their socio-economic position. It has been widely argued that the presence of such social determinants in health provides good reasons to reject luck egalitarianism as a theory of distributive justice in health. The literature provides different reasons why this responsibility-sensitive theory of distributive justice should not be applied to health. The critiques submit that the social circumstances undermine or remove people’s responsibility for their health; responsibility sensitive (...) health policies would adversely affect those who are worst off and; the luck egalitarian approach to health distracts from the important task of rectifying socio-economic influences on people's health and provides individualistic solutions to collective problems. But for each of these variants of the critique luck egalitarianism provides suitable answers. The literature on social determinants is no detriment to the project of applying luck egalitarianism to health. (shrink)

The difference between the unity of the individual and the separateness of persons requires that there be a shift in the moral weight that we accord to changes in utility when we move from making intrapersonal tradeoffs to making interpersonal tradeoffs. We examine which forms of egalitarianism can, and which cannot, account for this shift. We argue that a form of egalitarianism which is concerned only with the extent of outcome inequality cannot account for this shift. We also (...) argue that a view which is concerned with both outcome inequality and with the unfairness of inequality in individuals‘ expected utilities can account for this shift. Finally, we limn an alternative view, on.. (shrink)

Luck egalitarianism is a family of egalitarian theories of distributive justice that give a special place to luck, choice, and responsibility. These theories can be understood as responding to perceived weaknesses in influential earlier theories of both the left – in particular Rawls’ liberal egalitarianism (1971) – and the right – Nozick’s libertarianism (1974) stands out here. Rawls put great emphasis on the continuity of his theory with the great social contract theories of modern political thought, particularly emphasising (...) its Kantian character, while Nozick overtly develops his theory as an elaboration of John Locke’s account of property. By contrast, how luck egalitarianism is related to the history of political thought or philosophy more generally has been left unexplored by its proponents. Perhaps this is because they see luck egalitarianism, with its focus on individual choice and association with such contemporary concerns as equality of opportunity, as without significant predecessors in the canon. My purpose in this chapter is to make the tentative first steps towards identifying some historical antecedents of luck egalitarianism among the main works of Western political thought, in particular Aristotle, Machiavelli, and Locke.

Luck egalitarianism’s commitment to neutralizing brute luck inequalities is thought to imply that the elimination of disabilities is an appropriate way to eliminate the unchosen disadvantage that often accompanies disabilities. This implication is not only intuitively objectionable to some, especially those concerned with disability justice, but is subject to objections from relational egalitarians that should be taken seriously. This paper defends the claim that disability elimination is not a natural implication of luck egalitarian theories of justice and that luck (...) egalitarians can avoid the related relational egalitarian objections. I take this to be the case because luck egalitarians can consistently endorse three commitments that, together, take disability elimination off the menu of possible ways to redress the disadvantage of persons with disabilities. These three commitments are: i) the rejection of the view that disability intrinsically makes a person worse off; ii) the endorsement of the fundamental equality of all persons; and iii) the view that luck egalitarianism advances a theory about the arrangement of social institutions.

Luck egalitarians argue that distributive justice should be understood in terms of our capacity to be responsible for our choices. Both proponents and critics assume that the theory must rely on a comprehensive conception of responsibility. I respond to luck egalitarianism’s critics by developing a political conception of responsibility that remains agnostic on the metaphysics of free choice. I construct this political conception by developing a novel reading of John Rawls’ distinction between the political and the comprehensive. A surprising (...) consequence is that many responsibility-based objections to luck egalitarianism turn out to be objections to Rawls’ political liberalism as well. (shrink)

Most philosophers discuss the Repugnant Conclusion as an objection to total utilitarianism. But this focus on total utilitarianism seems to be one-sided. It conceals the important fact that other competing moral theories are also subject to the Repugnant Conclusion. The primary aim of this paper is to demonstrate that versions of egalitarianism are subject to the Repugnant Conclusion and other repugnant conclusions.

This dissertation identifies and responds to a problem for liberal relational egalitarians. There is a prima facie worry about the compatibility of liberalism and relational egalitarianism, concerning the requirements of equality in informal social life. Liberalism at least involves a commitment to leaving individuals substantial discretion to pursue their own conceptions of the good. Relational equality is best understood as a kind of deliberative practice about social institutions and practices. Patterns of otherwise innocuous social choices (e.g., where to live, (...) whom to befriend or marry) can create emergent, severe differentials in power, status, and influence, and when they do they can threaten relational equality. If relational equality required individuals to subordinate personal choices to egalitarian considerations, it would run into conflict with liberal commitments. In response, I defend the value of accepting an imperfect realization of relational equality. What I call fair relational equality demands that members of society treat some informal social norms and practices as part of the basic structure of society, in need of justification. Three practices are required to meet that demand. First, the relational-egalitarian society must develop institutional strategies to preempt or mitigate tendencies toward emergent inequality as they are identified. Second, members of society must engage in broad social deliberation about the norms and expectations of informal social interaction. Third, they must be willing to reform social practices where doing so does not impinge on important personal projects and values. (shrink)

This paper gives an outline of truthmaker semantics for natural language against the background of standard possible-worlds semantics. It develops a truthmaker semantics for attitude reports and deontic modals based on an ontology of attitudinal and modal objects and on a semantic function of clauses as predicates of such objects. It also présents new motivations for 'object-based truthmaker semantics' from intensional transitive verbs such as ‘need’, ‘look for’, ‘own’, and ‘buy’ and gives an outline of their semantics. This paper (...) is a commissioned 'target' article, with commentaries by W. Davis, B. Arsenijevic, K. Moulton, K. Liefke, M. Kaufmann, R. Matthews, P. Portner and A. Rubinstein, P. Elliott, G.

In this article, I reply to some criticisms of my book, Pragmatist Egalitarianism, offered by professors Robert Talisse, Susan Dieleman, and Alexander Livingston. Some of the major themes and questions I address include the following: How are conflicts between different egalitarian ideals best understood and addressed? Does the quest for equality have a fundamental locus, or are the different egalitarian variables I identify in the book, conceptually speaking, on an equal footing? What is the relationship between justice and equality? (...) How are feminist egalitarianism and Marxian egalitarianism best slotted into my distinction between “vertical” and “horizontal” egalitarianism? What does liberalism, problematic though it may sometimes be, have to contribute to the egalitarian project? (shrink)

Many political theorists defend the view that egalitarian justice should extend from the domestic to the global arena. Despite its intuitive appeal, this ‘global egalitarianism’ has come under attack from different quarters. In this article, we focus on one particular set of challenges to this view: those advanced by domestic egalitarians. We consider seven types of challenges, each pointing to a specific disanalogy between domestic and global arenas which is said to justify the restriction of egalitarian justice to the (...) former, and argue that none of them – both individually and jointly – offers a conclusive refutation of global egalitarianism.

This paper is about the relationship between two questions: the question of what the objects of assertion are and the question of how best to theorise about ‘shifty’ phenomena like modality and tense. I argue that the relationship between these two questions is less direct than is often supposed. I then explore the consequences of this for a number of debates in the philosophy of language.

This paper identifies a challenge for liberal relational egalitarians—namely, how to respond to the prospect of emergent inequalities of power, status, and influence arising unintentionally through the free exercise of fundamental individual liberties over time. I argue that these emergent social inequalities can be produced through patterns of nonmalicious choices, that they can in fact impede the full realization of relational equality, and that it is possible they cannot be eliminated entirely without abandoning fundamental liberal commitments to leave individuals substantial (...) discretion in their personal lives. In such cases, I argue that liberal egalitarians should accept fair relational equality—a demanding but nevertheless imperfect form of relational equality. (shrink)

This paper challenges the negative attitudes towards labelled proof systems, usually referred to as semantic pollution, by arguing that such critiques overlook the full potential of labelled calculi. The overarching objective is to develop a practice-based philosophical analysis of labelled calculi to provide insightful considerations regarding their proof-theoretic and philosophical value. To achieve this, successful applications of labelled calculi and related results will be showcased, and comparisons with other relevant works will be discussed. The paper ends by advocating for (...) a more practice-based approach towards the philosophical understanding of proof systems and their role in structural proof theory. (shrink)

The late G.A. Cohen is routinely considered a founding father of luck egalitarianism, a prominent responsibility-sensitive theory of distributive justice. David Miller argues that Cohen’s considered beliefs on distributive justice are not best understood as luck egalitarian. While the relationship between distributive justice and personal responsibility plays an important part in Cohen’s work, Miller maintains that it should be considered an isolated theme confined to Cohen’s exchange with Dworkin. We should not understand the view Cohen defends in this exchange (...) as Cohen’s considered view. Accepting this thesis would change both our understanding of Cohen’s political philosophy and many recent luck egalitarian contributions. Miller’s argument offers an opportunity to reassess Cohen’s writings as a whole. Ultimately, however, the textual evidence against Miller’s argument is overwhelming. Cohen clearly considers the exchange with Dworkin to be about egalitarianism as such rather than about the best responsibility-sensitive version of egalitarianism. Furthermore, Cohen often offers luck egalitarian formulations of his own view outside of the exchange with Dworkin and uses luck egalitarianism as an independent yardstick for evaluating principles and distributions.

This article begins by distinguishing force and mood. Then it lays out desiderata on a successful account. It sketches as background the program of truth-theoretic semantics. Next, it surveys assimilation approaches and argues that they are inadequate. Then it shows how the fulfillment-conditional approach can be applied to imperatives, interrogatives, molecular sentences containing them, and quantification into mood markers. Next, it considers briefly the recent set of propositions approach to the semantics of interrogatives and exclamatives. Finally, it shows how to (...) integrate exclamatives and optatives into a framework similar to the fulfillment approach. (shrink)

Luck egalitarianism has been criticized for condoning some cases of oppression and condemning others for the wrong reason—namely, that the victims were not responsible for their oppression. Oppression is unjust, however, the criticism says, regardless of whether victims are responsible for it, simply because it is contrary to the equal moral standing of persons. I argue that four luck egalitarian responses to this critique are inadequate. Two address only the first part of the objection and do so in a (...) way that risks making luck egalitarianism inconsistent. A third severely dilutes the luck egalitarian doctrine. A fourth manages to denounce some instances of oppression for the right reason, but at the same time permits other instances of oppression and condemns yet others for the wrong reason. (shrink)

The chapter explores whether, or to what extent, recent work in experimental philosophy puts pressure on the idea that the concept of causation is ‘egalitarian’. Causal selection – where experimental subjects tend to rate the causal strength of (for example) a norm-violator more strongly than a non-norm-violator – is a well established phenomenon, and is in prima facie tension with an egalitarian conception of causation; it also, indirectly, puts prima facie pressure on the idea that causation is a worldly phenomenon (...) whose obtaining is independent of facts about norms. The chapter explores both the various psychological mechanisms and the broadly pragmatic approaches to explaining causal selection. It argues that the answer to the question whether or not the concept of causation is egalitarian is currently significantly empirically underdetermined, and suggests some avenues for further investigation.

Several attempts have been made to apply the choice-sensitive theory of distributive justice, luck egalitarianism, in the context of health and healthcare. This article presents a framework for this discussion by highlighting different normative decisions to be made in such an application, some of the objections to which luck egalitarians must provide answers and some of the practical implications associated with applying such an approach in the real world. It is argued that luck egalitarians should address distributions of health (...) rather than healthcare, endorse an integrationist theory that combines health concerns with general distributive concerns and be pluralist in their approach. It further suggests that choice-sensitive policies need not be the result of applying luck egalitarianism in this context. (shrink)

The notion of existence is a very puzzling one philosophically. Often philosophers have appealed to linguistic properties of sentences stating existence. However, the appeal to linguistic intuitions has generally not been systematic and without serious regard of relevant issues in linguistic semantics. This paper has two aims. On the one hand, it will look at statements of existence from a systematic linguistic point of view, in order to try to clarify what the actual semantics of such statements in fact is. (...) On the other hand, it will explore what sort of ontology such statements reflect. The first aim is one of linguistic semantics; the second aim is one of descriptive metaphysics. Philosophically, existence statements appear to reflect the distinction between endurance and perdurance as well as particular notions of abstract states and of kinds. Linguistically, statements of existence involve a particular way of drawing the distinction between eventive and stative verbs and between individual-level and stage-level predicates as well as a particular approach to the semantics of bare plurals and mass nouns.

This paper establishes a sound and complete semantics for the impure logic of ground. Fine (Review of Symbolic Logic, 5(1), 1–25, 2012a) sets out a system for the pure logic of ground, one in which the formulas between which ground-theoretic claims hold have no internal logical complexity; and it provides a sound and complete semantics for the system. Fine (2012b) [§§6-8] sets out a system for an impure logic of ground, one that extends the rules of the original pure system (...) with rules for the truth-functional connectives, the first-order quantifiers, and λ-abstraction. However, no semantics has yet been provided for this system. The present paper partly fills this lacuna by providing a sound and complete semantics for a system GG containing the truth-functional operators that is closely related to the truth-functional part of the system of Fine (2012b).

I argue that semantics is the study of the proprietary database of a centrally inaccessible and informationally encapsulated input–output system. This system’s role is to encode and decode partial and defeasible evidence of what speakers are saying. Since information about nonlinguistic context is therefore outside the purview of semantic processing, a sentence’s semantic value is not its content but a partial and defeasible constraint on what it can be used to say. I show how to translate this thesis (...) into a detailed compositional-semantic theory based on the influential framework of Heim and Kratzer. This approach situates semantics within an independently motivated account of human cognitive architecture and reveals the semantics–pragmatics interface to be grounded in the underlying interface between modular and central systems.

This chapter defends a view of semantics on which developing a semantic theory closely resembles developing a scale of measurement. The view helps explain how semantics has made so much progress despite deep disagreements about the target of semantic theorizing (e.g., between those who maintain that semantics is characterizing something psychological, and those who maintain that it is characterizing something social), how appeals to set-theoretic abstracta make sense despite Benacerraf-style worries and despite the fact that set-theoretic entities fit (...) badly with standard (e.g., causal) metasemantic views, and why the threat of radical context sensitivity does not undermine the semantic project.

Relationship between default semantics and modularity of mind (in particular mind reading through the principle of Relevance).

In this paper I show that we have strong empirical and theoretical reasons to treat the verbs we use in our semantic theorizing—particularly ‘refers to ’, ‘applies to ’, and ‘is true of ’—as intensional transitive verbs. Stating our semantic theories with intensional vocabulary allows us to partially reconcile two competing approaches to the nature and subject-matter of semantics: the Chomskian approach, on which semantics is non-relational, internalistic, and concerns the psychology of language users, and the Lewisian approach, (...) on which semantics is fully relational, specifies truth-conditions, and has metaphysical implications. ITVs have two readings: an intensional, de dicto reading, and a relational, de re reading. A semantic theory stated with the de dicto readings of our semantic verbs captures the core insights of the Chomskian approach to semantics, in part because it allows us to assign extremely fine-grained semantic values to expressions, even when those expressions are empty. On the other hand, the de re reading yields a theory that is fully relational, and issues in truth-conditions. The resulting theories are related—and compatible—in that they are expressed by two different readings of the very same semantic vocabulary, and plausibly, the distinction between these two readings is one of scope.

In “Is semantics possible?” Putnam connected two themes: the very possibility of semantics (as opposed to formal model theory) for natural languages and the proper semantic treatment of common nouns. Putnam observed that abstract semantic accounts are modeled on formal languages model theory: the substantial contribution is rules for logical connectives (given outside the models), whereas the lexicon (individual constants and predicates) is treated merely schematically by the models. This schematic treatment may be all that is needed for (...) an account of validity in a formal setting, but it does not help to understand how proper and common nouns function in reality (not in models). Putnam then initiated the empirical study of such nouns to indicate, (i), that the popular Frege-Carnap account of them as (“disguised” compound) predicates is empirically incorrect, and, (ii), that they offer a new paradigm for a naturalistic semantics of natural languages. We take Putnam’s program a couple of steps further. First, we investigate the semantics of common nouns and argue that they refer (to kinds), rather than apply by satisfaction/truth to a designation/denotation. Second, we point to general results about semantics as a theory whose fulcrum is the reference relation rather than satisfaction in models and validity across them. (shrink)

In the chapter “Information and Content” of their Impossible Worlds, Berto and Jago provide us with a semantic account of information in deductive reasoning such that we have an explanation for why some, but not all, logical deductions are informative. The framework Berto and Jago choose to make sense of the above-mentioned idea is a semantic interpretation of Sequent Calculus rules of inference for classical logic. I shall argue that although Berto and Jago’s idea and framework are hopeful, (...) their definitions do not capture what is intended. This is so because the definitions are solely based on the logical complexity of an argument and they fail to capture the richness of the non- logical content of that argument. Then I will suggest some amendments to address this problem. Finally, I will extend the application of the definitions to first-order logic. It shall be observed that in some classical deductions, applying contraction may lead to hiding some epistemic impossibilities. This happens when formulae which contribute different propositions to the proof get contracted at the quantified level. (shrink)

In the major French and German etymological dictionaries of Latin, there is some puzzlement over the semantics of exāmen: how can one word refer to a measurement or examination, but also to a swarm of bees? Walde and Hofmann suggest these two dis-parate meanings stem from the diverse meanings of the verb exigō (<*ex-agō, ‘to drive out’), from which exāmen derives. They claim these two senses of exāmen become two words in the Latin Sprachgefühl. Ernout and Meillet agree: there is (...) more than one exāmen in the Latins’ sentiment linguistique. I, too, agree. But this approach does not tell us why these terms derive from exigō, nor does it give any hint of an underlying concept which measurements and swarms of bees share, which makes a derivation from exigō appropriate to both. The present paper addresses this puzzle by reducing the two meanings of exāmen to one meaning of the parent term *ex-agō: ‘to drive out.’ In sum: a swarm of bees is a ‘driving out’ or outpouring, and a measurement or examination is a ‘driving out’ or setting out for scrutiny. This interpretation is moreover supported by semantically parallel uses of cognate terms in other Indo-European languages, notably Greek and Old Irish, and by semantic parallels in English and in the Slavic language family. Along the way, I touch upon a philosophical puzzle: at what point do evolving linguistic items with a common source become distinct from one another? (shrink)

Abstract: This paper introduces and analyses the doctrine of externalism about semantic content; discusses the Twin Earth argument for externalism and the assumptions behind it, and examines the question of whether externalism about content is compatible with a privileged knowledge of meanings and mental contents.

At the heart of semantics in the 20th century is Frege’s distinction between sense and force. This is the idea that the content of a self-standing utterance of a sentence S can be divided into two components. One part, the sense, is the proposition that S’s linguistic meaning and context associates with it as its semantic interpretation. The second component is S’s illocutionary force. Illocutionary forces correspond to the three basic kinds of sentential speech acts: assertions, orders, and questions. (...) Forces are then kinds of acts in which propositions are deployed with certain purposes. I sketch a speech-act theoretic semantics in which that distinction does not hold. Instead of propositions and forces, the theory proposes proto-illocutionary acts and illocutionary acts. The orthodox notion of a proposition plays no role in the framework, which is a good thing, since that notion is deeply problematic. The framework also shows how expressionists, who embrace a sophisticated speech-act framework, face no Frege-Geach embedding problem, since the latter assumes the Sense/Force distinction. (shrink)

Research has indicated that microRNAs (miRNAs), a special class of non-coding RNAs (ncRNAs), can perform important roles in different biological and pathological processes. miRNAs’ functions are realized by regulating their respective target genes (targets). It is thus critical to identify and analyze miRNA-target interactions for a better understanding and delineation of miRNAs’ functions. However, conventional knowledge discovery and acquisition methods have many limitations. Fortunately, semantic technologies that are based on domain ontologies can render great assistance in this regard. In (...) our previous investigations, we developed a miRNA domain-specific application ontology, Ontology for MIcroRNA Target (OMIT), to provide the community with common data elements and data exchange standards in the miRNA research. This paper describes (1) our continuing efforts in the OMIT ontology development and (2) the application of the OMIT to enable a semantic approach for knowledge capture of miRNA-target interactions.

This paper discusses the roles of responsibility and desert in egalitarian theories of justice. It contrasts two main views of their relationship with justice: one according to which what justice requires depends on what people deserve (or are responsible for), and the other according to which what people deserve (or are responsible for) depends on what justice requires. The paper discusses how to interpret Rawls's remarks on desert in light of this distinction.

Intellectual humility is an interesting but underexplored disposition. The claim “I am (intellectually) humble” seems paradoxical in that someone who has the disposition in question would not typically volunteer it. There is an explanatory gap between the meaning of the sentence and the meaning the speaker expresses by uttering it. We therefore suggest analyzing intellectual humility semantically, using a psycholexical approach that focuses on both synonyms and antonyms of ‘intellectual humility’. We present a thesaurus-based method to map the semantic (...) space of intellectual humility as a heuristic to support philosophical and psychological analysis of this disposition. We find three semantic clusters that compose intellectual humility: the sensible self, the discreet self, and the inquisitive self; likewise, we find three clusters that compose its contraries: the overrated self, the underrated other, and the underrated self.

This paper considers issues raised by Elizabeth Anderson’s recent critique of the position she terms ‘luck egalitarianism’. It is maintained that luck egalitarianism, once clarified and elaborated in certain regards, remains the strongest egalitarian stance. Anderson’s arguments that luck egalitarians abandon both the negligent and prudent dependent caretakers fails to account for the moderate positions open to luck egalitarians and overemphasizes their commitment to unregulated market choices. The claim that luck egalitarianism insults citizens by redistributing on the (...) grounds of paternalistic beliefs, pity and envy, and by making intrusive and stigmatizing judgments of responsibility, fails accurately to characterize the luck egalitarian’s rationale for redistribution and relies upon luck egalitarians being insensitive to the danger of stigmatization. The luck egalitarian position is reinforced by the fact that Anderson’s favoured conception of equality, ‘democratic equality’, is counterintuitively indifferent to all unchosen inequalities, including intergenerational inequalities, once bare social minima are met.

Categorial logic, as its name suggests, applies the techniques and machinery of category theory to topics traditionally classified as part of logic. We claim that these tools deserve attention from a greater range of philosophers than just the mathematical logicians. We support this claim with an example. In this paper we show how one particular tool from categorial logic---hyperdoctrines---suggests interesting metaphysics. Hyperdoctrines can provide semantics for quantified languages, but this account of quantification suggests a metaphysical picture quite different from the (...) one suggested by standard model-theoretic semantics.

This book present a unified semantic theory of expressions involving the notions of part and whole. It develops a theory of part structures which differs from traditional (extensional) mereological theories in that the notion of an integrated whole plays a central role and in that the part structure of an entity is allowed to vary across different situations, perspectives, and dimensions. The book presents a great range of empirical generalizations involving plurals, mass nouns, adnominal and adverbial modifiers such as (...) 'whole', 'together', and 'alone', nominal and adverbial quanitfiers ranging over parts, and expressions of completion such as 'completely' and 'partly'. (shrink)

I develop and defend a truthmaker semantics for the relevant logic R. The approach begins with a simple philosophical idea and develops it in various directions, so as to build a technically adequate relevant semantics. The central philosophical idea is that truths are true in virtue of specific states. Developing the idea formally results in a semantics on which truthmakers are relevant to what they make true. A very natural notion of conditionality is added, giving us relevant implication. I then (...) investigate ways to add conjunction, disjunction, and negation; and I discuss how to justify contraposition and excluded middle within a truthmaker semantics. (shrink)

I consider what prima facie attractive communitarian ethical perspectives salient among indigenous African peoples entail for distributive justice within a state, and I argue that they support a form of economic egalitarianism that differs in several important ways from varieties common in contemporary Anglo-American political philosophy. In particular, the sort of economic egalitarianism I advance rivals not only luck-oriented variants from the likes of Ronald Dworkin, G. A. Cohen and theorists inspired by them such as Richard Arneson, Carl (...) Knight and Nir Eyal, but also more ‘social’ kinds advocated by Elizabeth Anderson, Samuel Scheffler and Jonathan Wolff. Although I do not argue that these broadly Kantian egalitarianisms are less plausible than the Afro-communitarian version, I do aim to establish that it should be taken as seriously as they, at this stage of the debate.

Philosophers and cognitive scientists have worried that research on animal mind-reading faces a ‘logical problem’: the difficulty of experimentally determining whether animals represent mental states (e.g. seeing) or merely the observable evidence (e.g. line-of-gaze) for those mental states. The most impressive attempt to confront this problem has been mounted recently by Robert Lurz. However, Lurz' approach faces its own logical problem, revealing this challenge to be a special case of the more general problem of distal content. Moreover, participants in this (...) debate do not agree on criteria for representation. As such, future debate should either abandon the representational idiom or confront underlying semantic disagreements. (shrink)

Philosophers have spilled a lot of ink over the past few years exploring the nature and significance of grounding. Kit Fine has made several seminal contributions to this discussion, including an exact treatment of the formal features of grounding [Fine, 2012a]. He has specified a language in which grounding claims may be expressed, proposed a system of axioms which capture the relevant formal features, and offered a semantics which interprets the language. Unfortunately, the semantics Fine offers faces a number of (...) problems. In this paper, I review the problems and offer an alternative that avoids them. I offer a semantics for the pure logic of ground that is motivated by ideas already present in the grounding literature, and for which a natural axiomatization capturing central formal features of grounding is sound and complete. I also show how the semantics I offer avoids the problems faced by Fine’s semantics. (shrink)

Cognition involves physical stimulation, neural coding, mental conception, and conscious perception. Beyond the neural coding of physical stimuli, it is not clear how exactly these component processes constitute cognition. Within mathematical sciences, category theory provides tools such as category, functor, and adjointness, which are indispensable in the explication of the mathematical calculations involved in acquiring mathematical knowledge. More speci cally, functorial semantics, in showing that theories and models can be construed as categories and functors, respectively, and in establishing the adjointness (...) between abstraction (of theories) and interpretation (to obtain models), mathematically accounts for knowing-within-mathematics. Here we show that mathematical knowing recapitulates--in an elementary form--ordinary cognition. The process of going from particulars (physical stimuli) to their concrete models (conscious percepts) via abstract theories (mental concepts) and measured properties (neural coding) is common to both mathematical knowing and ordinary cognition. Our investigation of the similarity between knowing-within-mathematics and knowing-in-general leads us to make a case for the development of the basic science of cognition in terms of the functorial semantics of mathematical knowing.
