This paper defends the autonomy thesis, which holds that one can intend to do something even though one believes it to be impossible, against attacks by Fred Adams. Adams denies the autonomy thesis on the grounds that it cannot, but must, explain what makes a particular trying, a trying for the aim it has in view. If the autonomy thesis were true, it seems that I could try to fly across the Atlantic ocean merely by typing out this abstract, a (...) palpable absurdity. If we deny the autonomy thesis, we have an easy explanation: one simply cannot try to do something which one believes to be impossible. In response, I argue, first, by means of examples, that one clearly can try and intend to do what one believes to be impossible; and then l show how we can provide an answer to Adams’s challenge even so.

(1) Content properties are nonrelational, that is, having a content property does not entail the existence of any contingent object not identical with the thinker or a part of the thinker.2 (2) We have noninferential knowledge of our conscious thoughts, that is, for any of our..

It is natural to think that our ordinary practices in giving explanations for our actions, for what we do, commit us to claiming that content properties are causally relevant to physical events such as the movements of our limbs and bodies, and events which these in turn cause. If you want to know why my body ambulates across the street, or why my arm went up before I set out, we suppose I have given you an answer when I say (...) that I wanted to greet a friend on the other side of the street, and thought that my arm's going up would be interpreted by him as a signal to stop for a moment. This widely held view might be disputed, but I shall not argue for it in this paper. I want to start with the view that our beliefs and desires and other propositional attitudes are causally relevant, in virtue of their modes and particular contents, to our movements, in order to investigate the consequences for analyses of thought content. For this purpose, I argue, in sec. II, for three necessary conditions on causal relevance: (a) a nomic sufficiency condition, (b) a logical independence condition, and (c) a screening-off condition. In sec. III, I apply these conditions to relational and functional theories of thought content, arguing that these theories cannot accommodate the causal relevance of content properties to our behaviour. I argue further that, on two plausible assumptions, one about the dependence of the mental on the physical, and the other about the availability in principle of causal explanations of our movements in terms of our non-relational physical properties, content properties can be causally relevant only if they are nomically type-correlated, relative to certain circumstances, with non-relational physical properties of our bodies. In sec. IV, I respond to a number of objections that might be advanced against this conclusion. (shrink)

How are we able to perceive the world veridically? If we ask this question as a part of the scientific investigation of perception, then we are not asking for a transcendental guarantee that our perceptions are by and large veridical; we presuppose that they are. Unless we assumed that we perceived the world for the most part veridically, we would not be in a position to investigate our perceptual abilities empirically. We are interested, then, not in how it is possible (...) in general for us to perceive the world veridically, but instead in what the relation is between our environment and its properties, of which we have knowledge, on the one hand, and our perceptual mechanisms, on the other, that results in very many, even most of our perceptions being veridical in everyday life. (shrink)

The paper rejects the claim that phenomena such as change and inattentional blindness show that perceptual representations are inaccurate or that a radical overhaul of our traditional picture of perception is required. The paper rejects in particular the sensorimotor theory of perception, which denies that there are any perceptual representations. It further argues that the degree of resolution of perceptual experience relevant to assessing its accuracy is determined by our use of it in standard conditions, and that the integration of (...) behavior with perceptual representation shows that it is by and large as accurate as its degree of resolution requires.

Fred Dretske has recently argued, in a highly original book and a series of articles, that action explanations are a very special species of historical explanation, in opposition to the traditional view that action explanations cite causes of actions, which are identical with bodily movements. His account aims to explain how it is possible for there to be a genuine explanatory role for reasons in a world of causes, and, in particular, in a world in which we have available in (...) principle an explanation for any movement of our bodies in neurophysiological terms. While Dretske draws attention to an important, and overlooked, feature of the form of the explananda of action explanations, he draws the wrong conclusion from it. This paper argues argues that his account of the nature of action explanations, and the role of reasons in explaining behavior, cannot be right. This will force us to re©examine the assumptions that suggest that reason explanations and neurophysiological explanations of our movements cannot coexist. (shrink)

Social externalism is the view that the contents of a person's propositional attitudes are logically determined at least in part by her linguistic community's standards for the use of her words. If social externalism is correct, its importance can hardly be overemphasized. The traditional Cartesian view of psychological states as essentially first personal and non-relational in character, which has shaped much theorizing about the nature of psychological explanation, would be shown to be deeply flawed. I argue in this paper that (...) social externalism faces insuperable difficulties. The first difficulty is that if syntax and semantics are independent, then social externalism is committed to the absurd consequence that many people have beliefs with formally inconsistent contents. I argue none of the possible responses to this objection are plausible. The second difficulty is that if syntax and semantics are independent, then social externalists are committed to a contradiction. After raising and defending these objections, I identify what I think is the underlying flaw in the social externalist position, a failure to pay attention to the structure of communication intentions, and briefly indicate how to neutralize the linguistic evidence social externalists advance in favor of their view.

Let us call a thought or belief whose content would be expressed by a sentence of subject-predicate form (by the thinker or someone attributing the thought to the thinker) an ‘ascription’. Thus, the thought that Madonna is middle-aged is an ascription of the property of being middle-aged to Madonna. To call a thought of this form an ascription is to emphasize the predicate in the sentence that gives its content. Let us call an ‘x-ascription’ an ascription whose subject is x, (...) that is, an ascription such that the subject of the sentence which would express its content is x. Let us call a ‘self-ascription’ an ascription whose subject is identical with the ascriber. Let us call a ‘reflexive ascription’ a selfascription such that either (i) in the sentence the ascriber would use to attribute correctly the ascription to himself he would use the first person pronoun to refer to himself both as the ascriber and as the subject of the ascription, as in a sentence of the form, I believe that I ö.

Philosophers constantly see the method of science before their eyes, and are irresistibly tempted to ask and answer questions in the way science does. This tendency is the real source of metaphysics and leads the philosopher into complete darkness.

There is a great deal of terminological confusion in discussions of holism. While some well-known authors, such as Davidson and Quine, have used “holism” in various of their writings,2 it is not clear that they have held views attributed to them under that label, views that are said to have wildly counterintuitive results.3 In Davidson’s case, it is not clear that he is describing the same doctrine in each of his uses of “holism” or “holistic.” Critics of holism show a (...) similar license. My aim in this paper, therefore, cannot be to provide and to examine a characterization of content holism that matches every use that has been made of the term. I aim rather to give a precise form to a holistic doctrine at one end of a spectrum of views that ranges from localism or atomism about content to holism about content. This view has the wild consequences often attributed to holism. While it is dubious that anyone has ever seriously held the view I characterize,4 some view like it seems to be what critics often have in mind when arguing against content holism. It is therefore worthwhile to make it precise, to distinguish it from other, related views, and to examine its internal coherence. Thus, in this paper, I will, first, clarify the doctrine, or a doctrine, of content holism, and, second, argue that content holism (so characterized) is not just false (which may be readily granted) but self-contradictory. To begin, we must distinguish between meaning holism and content holism. Let us reserve the term “meaning holism” for doctrines which are about the conditions for the possibility of linguistic expressions having meanings. Meaning holism is therefore a doctrine in the domain of the philosophy of language. “Content holism,” in contrast, we will treat as a doctrine in the philosophy of mind, about the conditions for the possibility of a thought5 having a content. By “a content” we mean, intuitively, what.. (shrink)

I begin by distinguishing between what I will call a pure Fregean theory of reference and a theory of direct reference. A pure Fregean theory of reference holds that all reference to objects is determined by a sense or content. The kind of theory I have in mind is obviously inspired by Frege, but I will not be concerned with whether it is the theory that Frege himself held.1 A theory of direct reference, as I will understand it, denies that (...) all reference to objects is determined by sense or content. We will also distinguish between a theory of reference for thought, and for language. This gives us a fourfold classification of theories. What is puzzling about direct reference theories is not that the semantics of an expression in a public language should assign as its semantic value just a referent, but how such facts could be understood to reflect an underlying feature of thought. There are two interconnected aspects to this.. (shrink)

Recent third person approaches to thought experiments and conceptual analysis through the method of surveys are motivated by and motivate skepticism about the traditional first person method. I argue that such surveys give no good ground for skepticism, that they have some utility, but that they do not represent a fundamentally new way of doing philosophy, that they are liable to considerable methodological difficulties, and that they cannot be substituted for the first person method, since the a priori knowledge which (...) is our object in conceptual analysis can be acquired only from the first person standpoint.

Existing work on gaslighting ties it constitutively to facts about the intentions or prejudices of the gaslighter and/or his victim’s prior experience of epistemic injustice. I argue that the concept of gaslighting is more broadly applicable than has been appreciated: what is distinctive about gaslighting, on my account, is simply that a gaslighter confronts his victim with a certain kind of choice between rejecting his testimony and doubting her own basic epistemic competence in some domain. I thus hold that gaslighting (...) is a purely epistemic phenomenon—not requiring any particular set of intentions or prejudices on the part of the gaslighter—and also that it can occur even in the absence of any prior experience of epistemic injustice. Appreciating the dilemmatic character of gaslighting allows us to understand its connection with a characteristic sort of epistemic harm, makes it easier to apply the concept of gaslighting in practice, and raises the possibility that we might discover its structure and the associated harm in surprising places.

The axiological question in the philosophy of religion is the question of what impact, if any, God’s existence does make to the axiological value of our world. It has recently been argued that we should prefer a theistic world where God is hidden to an atheistic world or a theistic world where God isn’t hidden. This is because in a hidden theistic world all of the theistic goods obtain in addition to the experience of atheistic goods. I complete this line (...) of argument by showing that theistic goods do indeed obtain in a world where God hides. In doing so I indirectly argue against proponents of divine hiddenness arguments such as J.L. Schellenberg. The correct answer to the axiological question turns out to be a solution to the problem of divine hiddenness. (shrink)

In this paper, we look at Bourbaki’s work as a case study for the notion of mathematical style. We argue that indeed Bourbaki exemplifies a mathematical style, namely the structuralist style.

This paper gives an account of proxy agency in the context of collective action. It takes the case of a group announcing something by way of a spokesperson as an illustration. In proxy agency, it seems that one person or subgroup's doing something counts as or constitutes or is recognized as (tantamount to) another person or group's doing something. Proxy agency is pervasive in institutional action. It has been taken to be a straightforward counterexample to an appealing deflationary view of (...) collective action as a matter of all members of a group making a contribution to bringing about some event. I show that this is a mistake. I give a deflationary account of constitutive rules in terms of essentially collective action types. I then give an account of one form of constitutive agency in terms of constitutive rules. I next give an account of status functions—of which being a spokesperson is one—that also draws on the concept of a constitutive rule. I then show how these materials help us to see how proxy agency is an expression of the agency of all members of the group credited with doing something when the proxy acts. (shrink)

A review essay on Peacocke's book A Study of Concepts.

This chapter argues that Davidson's truth-theoretic semantics was not intended to replace the traditional pursuit of providing a compositional meaning theory but rather to achieve the same aim indirectly by placing conditions on a truth theory that would enable someone who understood it to understand its object language. The chapter argues that by placing constraints on the axioms of a Tarski-style truth theory, namely, that they interpret the terms for which they give satisfaction conditions, and specifying a suitable canonical proof (...) procedure that issues in T-sentence that remove all the metalanguage semantic terms from the right hand side and draw intuitively only on the content of the axioms, we can use the theory to interpret object language sentences. It further argues that if we ask what body of knowledge one must be in possession of to interpret the language, it turns out to be a set of propositions about the truth theory but not the axioms of the truth theory itself. This shows how to avoid the problem of the semantic paradoxes and the problem of vagueness. (shrink)

Le réalisme scientifique occupe une place centrale dans le système philosophique de Mario Bunge. Au cœur de cette thèse, on trouve l’affirmation selon laquelle nous pouvons connaître le monde partiellement. Il s’ensuit que les théories scientifiques ne sont pas totalement vraies ou totalement fausses, mais plutôt partiellement vraies et partiellement fausses. Ces énoncés sur la connaissance scientifique, à première vue plausible pour quiconque est familier avec la pratique scientifique, demandent néanmoins à être clarifiés, précisés et, ultimement, à être inclus dans (...) un cadre théorique plus large et rigoureux. Depuis ses toutes premières publications sur ces questions et jusqu’à récemment, Mario Bunge n’a cessé d’interpeller les philosophes afin qu’ils développent une théorie, au sens propre du terme, de la vérité partielle afin de clarifier les enjeux épistémologiques liés au réalisme scientifique. Bunge a lui-même proposé plusieurs parties de cette théorie au fil des années, mais aucune de ces propositions ne l’a satisfait pleinement et la construction de cette théorie demeure un problème entier. Dans ce texte, nous passerons rapidement en revue certaines des approches proposées par Bunge dans ses publications et nous esquisserons certaines pistes qui devraient servir à tout le moins de desiderata pour la construction d’une théorie de la vérité partielle.

In this paper, I explore Bunge’s fictionism in philosophy of mathematics. After an overview of Bunge’s views, in particular his mathematical structuralism, I argue that the comparison between mathematical objects and fictions ultimately fails. I then sketch a different ontology for mathematics, based on Thomasson’s metaphysical work. I conclude that mathematics deserves its own ontology, and that, in the end, much work remains to be done to clarify the various forms of dependence that are involved in mathematical knowledge, in particular (...) its dependence on mental/brain states and material objects.

This chapter introduces readers to the empirical questions at issue in debates over gendered pronouns and assesses the plausibility of various possible answers to these questions. It has two parts. The first is a general introduction to the linguistics and psychology of grammatical gender. The second focuses on the meanings of gendered pronouns in English. It begins with a discussion of some methodological limitations of empirical approaches to the topic and the normative implications of those limitations. It then argues against (...) three simple theories of the semantics of gendered pronouns in English and proposes an alternative that fares better: the Gender-First View. Finally, it discusses the singular use of 'they' and its connection to nonbinary gender identities. (shrink)

Structuralism has recently moved center stage in philosophy of mathematics. One of the issues discussed is the underlying logic of mathematical structuralism. In this paper, I want to look at the dual question, namely the underlying structures of logic. Indeed, from a mathematical structuralist standpoint, it makes perfect sense to try to identify the abstract structures underlying logic. We claim that one answer to this question is provided by categorical logic. In fact, we claim that the latter can be seen—and (...) probably should be seen—as being a structuralist approach to logic and it is from this angle that categorical logic is best understood.

Olle Blomberg challenges three claims in my book From Individual to Plural Agency (Ludwig, Kirk (2016): From Individual to Plural Agency: Collective Action 1. Vols. 2. Oxford: Oxford University Press.). The first is that there are no collective actions in the sense in which there are individual actions. The second is that singular action sentences entail that there is no more than one agent of the event expressed by the action verb in the way required by that verb (the (...) sole agency requirement). The third, is that an individual intention, e.g. to build a boat, is not satisfied if you don’t do it yourself. On the first point, I grant that Blomberg identifies an important distinction between simple and composite actions the book did not take into account, but argue it doesn’t show that there are collective actions in the same sense there are individual actions. On the second point, I argue from examples that the collective reading of plural action sentences doesn’t entail the distributive reading, which requires the sole agency requirement on singular action sentences. This settles the third point, since it entails that if you intend to build a boat, you are successful only if you are the only agent of it in the sense required by the verb. (shrink)

The three major classical accounts of the morality of abortion are all subject to at least one major problem. Can we do better? This article aims to discuss three accounts that purport to be superior to the classical accounts. First, it discusses the future of value argument for the immorality of abortion. It defends the claim that the future of value argument is superior to all three of the classical accounts. It then goes on to discuss Warren's attempt to fix (...) up her personhood account and David Boonin's attempt to fix up Tooley's desire account. Warren claims that her updated version of a personhood account is superior to any potentiality account, such as the future of value account. The article evaluates her claim. Boonin argues that his improved desire view both deals adequately with the apparent counterexamples to Tooley's original account and also is superior to the future of value account. The article evaluates his views as well. (shrink)

Fefermans argument is indeed convincing in a certain context, it can be dissolved entirely by modifying the context appropriately.

This paper shows that recent arguments from group problem solving and task performance to emergent group level cognition that rest on the social parity and related principles are invalid or question begging. The paper shows that standard attributions of problem solving or task performance to groups require only multiple agents of the outcome, not a group agent over and above its members, whether or not any individual member of the group could have accomplished the task independently.

Corporations have often been taken to be the paradigm of an organization whose agency is autonomous from that of the successive waves of people who occupy the pattern of roles that define its structure, which licenses saying that the corporation has attitudes, interests, goals, and beliefs which are not those of the role occupants. In this essay, I sketch a deflationary account of agency-discourse about corporations. I identify institutional roles with a special type of status function, a status role, in (...) which the collectively accepted function is expressed in part through its occupier’s intentional expression of her agency in that role. I identify institutions as systems of status roles and show how this is compatible with seeing the agency of institutions generally, even over time periods in which there is complete change in role occupiers, as a matter of the contributions only of individual agents. I explain how the reduction of the institution to its members is compatible with its potentially having had a completely different membership. I show in the case of the corporation in particular that, once we see its origins and function, the surface features of legal discourse about corporate agency are misleading and are compatible with a deflationary account of corporate agency. I show in connection with this that the corporation is to be identified with its shareholders, and that where a corporation separates ownership and control, its managers and employees are proxy agents of the shareholders doing business under the corporate form. Finally, I canvass the legitimate ways of construing ordinary talk about corporate intention, belief, and so on, in light of this, none of which support the attribution of genuine agency or intentionality to any group per se associated with the corporation.

In proxy assertion an individual or group asserts something through a spokesperson. The chapter explains proxy assertion as resting on the assignment of a status role to a person (that of spokesperson) whose utterances acts in virtue of that role have the status function of signaling that the principal is committed in a way analogous to an individual asserting that in his own voice. The chapter briefly explains how status functions and status roles are grounded and then treats, in turn, (...) the case of a spokesperson for an individual and a group and the differences in the significance of what the spokesperson does in each case. Finally, it reviews complications introduced by spokesperson autonomy, where the spokesperson is given leave to represent her principal’s views or positions in her own words and to respond to questions on his behalf.

In this paper, following the claims made by various mathematicians, I try to construct a theory of levels of abstraction. I first try to clarify the basic components of the abstract method as it developed in the first quarter of the 20th century. I then submit an explication of the notion of levels of abstraction. In the final section, I briefly explore some of main philosophical consequences of the theory.

The term 'covert mixed quotation' describes cases in which linguistic material is interpreted in the manner of mixed quotation — that is, used in addition to being mentioned — despite the superficial absence of any commonly recognized conventional devices indicating quotation. After developing a novel theory of mixed quotation, I show that positing covert mixed quotation allows us to give simple and unified treatments of a number of puzzling semantic phenomena, including the projective behavior of conventional implicature items embedded in (...) indirect speech reports and propositional attitude ascriptions, so-called 'c-monsters,' metalinguistic negation, metalinguistic negotiation, and 'in a sense' constructions.

This paper offers an analysis of the logical form of plural action sentences that shows that collective actions so ascribed are a matter of all members of a group contributing to bringing some event about. It then uses this as the basis for a reductive account of the content of we-intentions according to which what distinguishes we-intentions from I-intentions is that we-intentions are directed about bringing it about that members of a group act in accordance with a shared plan.

The paper provides a taxonomy of group speech acts whose main division is that between collective speech acts (singing Happy Birthday, agreeing to meet) and group proxy speech acts in which a group, such as a corporation, employs a proxy, such as a spokesperson, to convey its official position.

In a recent article, Ireneusz Zieminski argues that the main goals of philosophy of religion are to define religion; assess the truth value of religion and; assess the rationality of a religious way of life. Zieminski shows that each of these goals are difficult, if not impossible, to achieve. Hence, philosophy of religion leads to scepticism. He concludes that the conceptual tools philosophers of religion employ are best suited to study specific religious traditions, rather than religion more broadly construed. But (...) it’s unclear whether the goals Zieminski attributes to philosophy of religion are accurate or even necessary for successful inquiry. I argue that an essentialist definition of religion isn’t necessary for philosophy of religion and that philosophers of religion already use the conceptual analysis in the way Zieminski suggests that they should. Finally, the epistemic standard Zieminski has in view is often obscure. And when it is clear, it is unrealistically high. Contemporary philosophers of religion rarely, if ever, claim to be offering certainty, or even evidence as strong as that found in the empirical sciences. (shrink)

Cooperation admits of degrees. When factory workers stage a slowdown, they do not cease to cooperate with management in the production of goods altogether, but they are not fully cooperative either. Full cooperation implies that participants in a joint action are committed to rendering appropriate contributions as needed toward their joint end so as to bring it about, consistently with the type of action and the generally agreed upon constraints within which they work, as efficiently as they can, where their (...) contributions are sensitive to information (where available) about how others are contributing in the sense that they adjust as needed their contributions in light of information about how others are contributing to ensure effective pursuit of their joint end, where this includes rendering aid to other participants if needed, insofar as they are able. Full cooperation entails those cooperating are engaged in a joint intentional action. Some prominent studies of joint intentional action focus exclusively on cases of full cooperation (notably that of Michael Bratman (2014)). But not all joint intentional action is fully cooperative. One example is the work slowdown. Another example is provided by competitive games like chess and football, or sports like boxing and wrestling, where participants are clearly not intending to contribute to the pursuit of all of the goals of the others engaged in the activity, even when those goals are internal to the type of activity in question, but instead intend actively to frustrate some of them. In this paper, I provide a taxonomy of forms of non-cooperative behavior within the context of behavior that is still to some degree cooperative, and I argue that the minimal conditions of joint intentional action define minimal cooperative behavior, that is, that minimally joint intentional action is per se minimally cooperative behavior. I define in precise terms what that comes to, and how it is possible in cases in which it seems that one or more participants are in one or more ways acting so as to frustrate the contributions of other participants to their joint action.

What is the ontology of collective action? I have in mind three connected questions. 1. Do the truth conditions of action sentences about groups require there to be group agents over and above individual agents? 2. Is there a difference, in this connection, between action sentences about informal groups that use plural noun phrases, such as ‘We pushed the car’ and ‘The women left the party early’, and action sentences about formal or institutional groups that use singular noun phrases, such (...) as ‘The United States declared war on Japan on December 8th, 1941’ and ‘The Supreme Court ruled that segregation is unconstitutional in 1954 in Brown vs. Board of Education’? 3. Under what conditions does it make sense to speak of a group doing something together, and what, if anything, is a collective action? In this paper, I argue that a) understanding action sentences about groups does not commit us to the existence of group agents per se, but only to the existence of individual agents; b) there is no difference in this regard between sentences which attribute actions to informal groups on the one hand and institutional groups on the other; c) collective action can be both intentional and unintentional; d) any random group of agents each of whom does something is also a group which does something together; e) while there is a sense in which groups per se perform no primitive collective actions, and therefore no actions at all, f) there is a sensible extension of talk of actions to groups, though it should be treated strictly speaking, like talk of group agents, as a façon de parler, for g) the only agents per se are individuals and the only actions are theirs. -/-.

It is generally assumed that existing artificial systems are not phenomenally conscious, and that the construction of phenomenally conscious artificial systems would require significant technological progress if it is possible at all. We challenge this assumption by arguing that if Global Workspace Theory (GWT) — a leading scientific theory of phenomenal consciousness — is correct, then instances of one widely implemented AI architecture, the artificial language agent, might easily be made phenomenally conscious if they are not already. Along the way, (...) we articulate an explicit methodology for thinking about how to apply scientific theories of consciousness to artificial systems and employ this methodology to arrive at a set of necessary and sufficient conditions for phenomenal consciousness according to GWT.

This chapter argues that while quotation marks are polysemous, the thread that runs through all uses of quotation marks that involve reference to expressions is pure quotation, in which an expression formed by enclosing another expression in quotation marks refers to that enclosed expression. We defend a version of the so-called disquotational theory of pure quotation and show how this device is used in direct discourse and attitude attributions, in exposition in scholarly contexts, and in so-called mixed quotation in indirect (...) discourse and attitude attributions. We argue that uses of quotation marks that extend beyond pure quotation have two features in common. First, the expressions appearing in quotation marks are intended to be understood, and that they are intended to be understood is essential to the function that such quotations play in communication, though this does not always involve the expressions contributing their extensional properties to fixing truth conditions for the sentences in which they appear. Second, they appeal to a relation to the expression appearing in quotation marks that plays a role in determining the truth conditions of the sentences in which they appear. (shrink)

Scientists use models to know the world. It i susually assumed that mathematicians doing pure mathematics do not. Mathematicians doing pure mathematics prove theorems about mathematical entities like sets, numbers, geometric figures, spaces, etc., they compute various functions and solve equations.

I focus on one area of mathematics where models occupy a central role, namely homotopy theory. (...) I argue that mathematicians introduce genuine models and I offer a rough classification of these models. (shrink)

This chapter argues that in cases in which a (non-institutional) group is collectively causally responsible and collectively morally responsible for some harm which is either (i) brought about intentionally or (ii) foreseen as the side effect of something brought about intentionally or (iii) unforeseen but a nonaggregative harm, each member of the group is equally and as fully responsible for the harm as if he or she had done it alone.

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)

A sorites argument is a symptom of the vagueness of the predicate with which it is constructed. A vague predicate admits of at least one dimension of variation (and typically more than one) in its intended range along which we are at a loss when to say the predicate ceases to apply, though we start out confident that it does. It is this feature of them that the sorites arguments exploit. Exactly how is part of the subject of this paper. (...) The majority of philosophers writing on vagueness take it to be a kind of semantic phenomenon. If we are right, they are correct in this assumption, which is surely the default position, but they have not so far provided a satisfactory account of the implications of this or a satisfactory diagnosis of the sorites arguments. Other philosophers have urged more exotic responses, which range from the view that the fault lies not in our language, but in the world, which they propose to be populated with vague objects which our semantics precisely reflects, to the view that the world and language are both perfectly in order, but that the fault lies with our knowledge of the properties of the words we use (epistemicism). In contrast to the exotica to which some philosophers have found themselves driven in an attempt to respond to the sorites puzzles, we undertake a defense of the commonsense view that vague terms are semantically vague. Our strategy is to take fresh look at the phenomenon of vagueness. Rather than attempting to adjudicate between different extant theories, we begin with certain pre-theoretic intuitions about vague terms, and a default position on classical logic. The aim is to see whether (i) a natural story can be told which will explain the vagueness phenomenon and the puzzling nature of soritical arguments, and, in the course of this, to see whether (ii) there arises any compelling pressure to give up the natural stance. We conclude that there is a simple and natural story to be told, and we tell it, and that there is no good reason to abandon our intuitively compelling starting point. The importance of the strategy lies in its dialectical structure. Not all positions on vagueness are on a par. Some are so incredible that even their defenders think of them as positions of last resort, positions to which we must be driven by the power of philosophical argument. We aim to show that there is no pressure to adopt these incredible positions, obviating the need to respond to them directly. If we are right, semantic vagueness is neither surprising, nor threatening. It provides no reason to suppose that the logic of natural languages is not classical or to give up any independently plausible principle of bivalence. Properly understood, it provides us with a satisfying diagnosis of the sorites argumentation. It would be rash to claim to have any completely novel view about a topic so well worked as vagueness. But we believe that the subject, though ancient, still retains its power to inform and challenge us. In particular, we will argue that taking seriously the central phenomenon of predicate vagueness—the “boundarylessness” of vague predicates—on the commonsense assumption that vagueness is semantic, leads ineluctably to the view that no sentences containing vague expressions (henceforth ‘vague sentences’) are truth-evaluable. This runs counter to much of the literature on vagueness, which commonly assumes that, though some applications of vague predicates to objects fail to be truth-evaluable, in clear positive and negative cases vague sentences are unproblematically true or false. It is clarity on this, and related points, that removes the puzzles associated with vagueness, and helps us to a satisfying diagnosis of why the sorites arguments both seem compelling and yet so obviously a bit of trickery. We give a proof that semantically vague predicates neither apply nor fail-to-apply to anything, and that consequently it is a mistake to diagnose sorites arguments, as is commonly done, by attempting to locate in them a false premise. Sorites arguments are not sound, but not unsound either. We offer an explanation of their appeal, and defend our position against a variety of worries that might arise about it. The plan of the paper is as follows. We first introduce an important distinction in terms of which we characterize what has gone wrong with vague predicates. We characterize what we believe to be our natural starting point in thinking about the phenomenon of vagueness, from which only a powerful argument should move us, and then trace out the consequences of accepting this starting point. We consider the charge that among the consequences of semantic vagueness are that we must give up classical logic and the principle of bivalence, which has figured prominently in arguments for epistemicism. We argue there are no such consequences of our view: neither the view that the logic of natural languages is classical, nor any plausible principle of bivalence, need be given up. Next, we offer a diagnosis of what has gone wrong in sorites arguments on the basis of our account. We then present an argument to show that our account must be accepted on pain of embracing (in one way or another) the epistemic view of “vagueness”, i.e., of denying that there are any semantically vague terms at all. Next, we discuss some worries that may arise about the intelligibility of our linguistic practices if our account is correct. We argue none of these worries should force us from our intuitive starting point. Finally, we cast a quick glance at other forms of semantic incompleteness. (shrink)

Legal norms are an invention. This paper advances a proposal about what kind of invention they are. The proposal is that legal norms derive from rules which specify role functions in a legal system. Legal rules attach to agents in virtue of their status within the system in which the rules operate. The point of legal rules or a legal system is to solve to large scale coordination problems, specifically the problem of organizing social and economic life among a group (...) of people and their successors, though not every legal rule pertains to a coordination problem. The framework for thinking about legal norms that I describe is a framework for thinking about institutions and policies more generally. The idea is to show that legal norms are a species of institutional norm. There are two central ideas. The first is the idea of a role in an institution. The second is the idea of proxy agency. Proxy agency involves one agent or group acting under the authorization of another agent or group (perhaps subsuming it) in a way that makes the actions of the proxy count as actions (under a description) of the individual or group for which it is a proxy. We get the characteristic structure of a legal system by conceiving of an institutional group, itself conceived of as a set of interlocking roles realized in individuals, as having one or more roles for proxy agents who are authorized by the group to make policy for the group. The set of rules governing the basic constitution of the group and spelling out the powers of the policy proxies determine fundamental norms for the group with specific role responsibilities attaching to particular positions in institutional arrangements. The policies determine further norms whose force derives from the fundamental norms. We must then say some further things to distinguish institutions and policies which we wish to designate as legal.

Let the label binary category terms refer to natural language expressions like ‘woman’, ‘man’, ‘female’, and ‘male’. Focusing on ‘woman’ and ‘female’, I develop a novel, empirically supported theory of the meanings of English binary category terms. Given plausible assumptions about the metaphysics of sex and gender, this gender-first theory predicts that the sentence ‘Trans women are women’ expresses a truth in all contexts and the sentence ‘Women are adult human females’ expresses a truth in most ordinary contexts — thus (...) that these two sentences can and usually do express logically consistent contents. The key feature of the proposed theory is that it treats both ‘woman’ and ‘female’ as sensitive to an individual’s gender when that individual belongs to a gendered category and to an individual’s sex otherwise. The existence and plausibility of a gender-first theory of this kind opens up conceptual room for trans-inclusive positions in the philosophy of sex and gender which endorse the claim that women are adult human females, thereby both accounting for trans women’s experiences of their bodies as female and helping to disarm the sentence ‘Women are adult human females’ as a trans-exclusionary slogan.

Quotation marks in natural language that do not function straightforwardly as devices for securing reference to linguistic objects have generally been categorized as instances of either mixed quotation or scare quotation. I argue that certain uses of quotation marks in natural language resist assimilation to either of these two theoretical categories, as well as to the more familiar categories of pure and direct quotation. It follows that we must recognize a novel type of quotation in natural language, which I call (...) dummy quotation because it involves the contribution of semantically minimal `dummy meanings' to composition. I develop a semantic theory of dummy quotation and show that it is better able than rival proposals to account for the troublesome examples in question. (shrink)

An important objection to sententialist theories of attitude reports is that they cannot accommodate the principle that one cannot know that someone believes that p without knowing what it is that he believes. This paper argues that a parallel problem arises for propositionalist accounts that has gone largely unnoticed, and that, furthermore, the usual resources for the propositionalist do not afford an adequate solution. While non-standard solutions are available for the propositionalist, it turns out that there are parallel solutions that (...) are available for the sententialist. Since the difficulties raised seem to show that the mechanism by which sentential complements serve to inform us about attitudes and about sentence meaning does not depend on their referring to propositions, this casts doubt on whether talk of propositions should retain a significant theoretical role in the enterprise of understanding thought, language and communication.

The aim of this paper is to clarify the role of category theory in the foundations of mathematics. There is a good deal of confusion surrounding this issue. A standard philosophical strategy in the face of a situation of this kind is to draw various distinctions and in this way show that the confusion rests on divergent conceptions of what the foundations of mathematics ought to be. This is the strategy adopted in the present paper. It is divided into 5 (...) sections. We first show that already in the set theoretical framework, there are different dimensions to the expression foundations of. We then explore these dimensions more thoroughly. After a very short discussion of the links between these dimensions, we move to some of the arguments presented for and against category theory in the foundational landscape. We end up on a more speculative note by examining the relationships between category theory and set theory. (shrink)

This paper is concerned with a recent, clever, and novel argument for the need for genuine collectives in our ontology of agents to accommodate the kinds of normative judgments we make about them. The argument appears in a new paper by David Copp, "On the Agency of Certain Collective Entities: An Argument from 'Normative Autonomy'" (Midwest Studies in Philosophy: Shared Intentions and Collective Responsibility, XXX, 2006, pp. 194-221; henceforth ‘ACE’), and is developed in Copp’s paper for this special journal issue, (...) “The Collective Moral Autonomy Thesis” (henceforth ‘CAT’). The argument goes as follows. -/- (1) We correctly assign blame (or obligations) to collectives in circumstances in which it would be a mistake to assign any (relevantly related) blame (or obligations) to their members. (2) If (1), then collectives are genuine agents over and above their members. (3) Therefore, collectives are genuine agents over and above their members. -/- Following Copp, I call (1) the Collective Moral Autonomy Thesis (CMA). Copp argues for CMA primarily by appeal to cases, but also offers two general arguments for it. In the cases that Copp describes, we are to judge that a collective act is blameworthy, though each member of the group that acts is blameless because he is merely following procedures appropriate for his participation, or because there are excusing factors, or because of overriding personal duties. -/- I argue that the case for CMA has not been made. In particular, I argue that, in each case in which we feel inclined to hold a group responsible for something but not its members, it is because -/- 1. we have accepted a false dilemma, that when no one agent is fully responsible for the action of a group of which he is a member, the only entity that could be responsible is the group as such, or 2. we have directed our attention to the wrong individual or individuals, or 3. we have become confused about the commitments of the individuals, or 4. we have mistaken ameliorating for excusing factors, or 5. we have mistaken moral blameworthiness and all-in rational blameworthiness, or 6. a combination of these things.

The inclusion problem for theories of gender arises when those theories inappropriately fail to include certain individuals in the gender categories to which they ought to belong. The inclusion problem affects both of the most influential traditions in feminist theorizing about gender: social-position accounts and identity accounts. I argue that the inclusion problem can be solved by adopting a structured theory of gender, which incorporates aspects of both social-position accounts and identity accounts. According to the theory I favor, an individual’s (...) gender is determined by their gender identity if they have one; otherwise, it is determined by their social position. My structured approach to gender offers a more direct solution to the gender inclusion problem than alternatives recently advocated by Barnes (2020), Jenkins (2023), and others. It also points the way to a simple solution to inclusion problems that arise at the level of gendered language. (shrink)
