In the Critique of Pure Reason, following his elucidation of the ‘postulates’ of possibility, actuality, and necessity, Kant makes a series of puzzling remarks. He seems to deny the somewhat metaphysically intuitive contention that the extension of possibility is greater than that of actuality, which, in turn, is greater than that of necessity. Further, he states that the actual adds nothing to the possible. This leads to the view, fairly common in the literature, that Kant holds that all modal categories, (...) in their empirical applications, are coextensive. I diverge from the common view. First, Kant is not committed to the coextensiveness thesis, understood as above. Instead, he espouses a weaker, epistemological version of the coextensiveness thesis, namely that what we can assert to be really possible is coextensive with what we cognize to be actual. Second, Kant's remarks are not intended to introduce a positive ontological thesis about the extensions of modal categories. Rather, he means to criticize a certain conception of modalities that was prevalent among his rationalist predecessors, i.e., the conception of modalities as various determinations that enter the intensions of concepts of things.

This chapter is concerned with the coextension difficulty for nominalist theories of properties that reject tropes alongside universals. After carefully explaining the coextension difficulty and describing the theories it targets, the chapter describes different solutions to the difficulty. These solutions differ with respect to how much involved they are into a dualist approach to coextension. A dualist approach to a case of coextension consists in agreeing with the realist that the relevant ascriptions of properties are numerically distinct. A monist approach (...) to a case of coextension consists in contending that the relevant ascriptions of properties are identical. In this chapter, I defend a monist approach to cases of coextension that appeals to a counterpart theory for propositions. (shrink)

I discuss an important feature of the notion of cause in Post. An. 1. 13, 78b13–28, which has been either neglected or misunderstood. Some have treated it as if Aristotle were introducing a false principle about explanation; others have understood the point in terms of coextensiveness of cause and effect. However, none offers a full exegesis of Aristotle's tangled argument or accounts for all of the text's peculiarities. My aim is to disentangle Aristotle's steps to show that he is arguing (...) in favour of a logical requirement for a middle term's being the appropriate cause of its explanandum. Coextensiveness between the middle term and the attribute it explains is advanced as a sine qua non condition of a middle term's being an appropriate or primary cause. This condition is not restricted either to negative causes or to middle terms in second‐figure syllogisms, but ranges over all primary causes qua primary. (shrink)

_ Source: _Page Count 18 Bart Streumer argues that all normative properties are descriptive properties. His first argument is based on the principle that necessarily coextensive predicates ascribe the same property, and the claim that there is a descriptive predicate that is necessarily coextensive with normative predicates. From this Streumer concludes that normative properties are identical with descriptive properties. I argue that, even if we accept, this conclusion does not follow. Normative properties could only be descriptive properties if (...) there is some descriptive way in which all instances of normative properties are similar. But Streumer does not show that, and the prospects for doing so are, I believe, not good. His second argument rests on the premise that the nature of normative properties cannot depend on which first order normative theory is true. I argue that this premise is false, and that the argument for it does not sit comfortably with. (shrink)

Supervenience in most of its guises entails necessary coextension. Thus theoretical supervenience entails nomically necessary coextension. Kim's result, thus strengthened, has yet to hit home. I suspect that many supervenience enthusiasts would cool at necessary coextension: they didn't mean to be saying anything quite so strong. Furthermore, nomically necessary coextension can be a good reason for property identification, leading to reducibility in principle. This again is more than many supervenience theorists bargained for. They wanted supervenience without reducibility. It is not (...) always available for this mediating role. (shrink)

Two cases are distinguished. In one case two predicates belong to distinct languages. A straight-forward argument is presented that the predicates might be synonymous without being coextensive. In the second case the predicates belong to the same language. Here the issue is more involved, but the same conclusion is reached.

One widely recognized difference between laws and accidental generalizations lies in the ability of the former versus the inability of the latter to support certain sorts of related subjunctive conditionals. Nelson Goodman's theory of projectibility is here evaluated on the basis of its implications for the relative acceptability of conflicting subjunctive conditionals or counterfactuals. It is argued that the theory's extensionalistic character precludes its dealing adequately with cases of a certain type in which the difference between two counterfactuals, one acceptable (...) and the other unacceptable, is clearly related to a difference in nomological status between their indicative counterparts.

Persons who are dangerous and legally responsible, but who have not yet committed any currently recognised criminal offence, fall within the gap left between the domains of criminal justice and civil commitment. Many jurisdictions operate legal regimes that permit the detention of such persons in order to prevent the occurrence of anticipated criminal harms. These regimes often either fail to respect the principle of proportionality or contradictorily treat a dangerous offender as both legally responsible and not responsible at the same (...) time. In response to these problems, a number of preventive detention models have been proposed. Retributivist models seek to prevent the occurrence of anticipated criminal harms by requiring blame on the dangerous person’s part in order to warrant detention. However, these models are ill-equipped to deal with the problem of coextensiveness; i.e., they struggle to comprehensively reconcile proportionality in punitive sentencing with the period over which dangerous persons remain dangerous and during which one might therefore want them to be incapacitated. In order to achieve comprehensive incapacitation of dangerous persons for the duration of their dangerousness, retributivist models are forced to abandon their fidelity to proportionality in punitive sentencing, thereby losing themselves in the process. Accordingly, if the practice of preventive detention can be justified at all, such justification will not be of a retributivist character. (shrink)

The word ‘equality’ often requires disambiguation, which is provided by context or by an explicit modifier. For each sort of magnitude, there is at least one sense of ‘equals’ with its correlated senses of ‘is greater than’ and ‘is less than’. Given any two magnitudes of the same sort—two line segments, two plane figures, two solids, two time intervals, two temperature intervals, two amounts of money in a single currency, and the like—the one equals the other or the one is (...) greater than the other or the one is greater than the other [sc. in appropriate correlated senses of ‘equals’, ‘is greater than’ and ‘is less than’]. In case there are two or more appropriate senses of ‘equals’, the one intended is often indicated by an adverb. For example, one plane figure may be said to be equal in area to another and, in certain cases, one plane figure may be said to be equal in length to another. Each sense of ‘equality’ is tied to a specific domain and is therefore non-logical. Notice that in every cases ‘equality’ is definable in terms of ‘is greater than’ and also in terms of ‘is less than’ both of which are routinely considered domain specific, non-logical. The word ‘identity’ in the logical sense does not require disambiguation. Moreover, it is not correlated ‘is greater than’ and ‘is less than’. If it is not the case that a certain designated triangle is [sc. is identical to] an otherwise designated triangle, it is not necessary for the one to be greater than or less than the other. Moreover, if two magnitudes are equal then a unit of measure can be chosen and, no matter what unit is chosen, each magnitude is the same multiple of the unit that the other is. But identity does not require units. In this regard, congruence is like identity and unlike equality. In arithmetic, the logical concept of identity is coextensive with the arithmetic concept of equality. The logical concept of identity admits of an analytically adequate definition in terms of logical concepts: given any number x and any number y, x is y iff x has every property that y has. The arithmetical concept of equality admits of an analytically adequate definition in terms of arithmetical concepts: given any number x and any number y, x equals y iff x is neither less than nor greater than y. As Aristotle told us and as Frege retold us, just because one relation is coextensive with another is no reason to conclude that they are one. (shrink)

In the first part of this paper I argue that beauty and goodness are at least coextensive for Plato. That means that at least with respect to concrete particulars, everything that is good is beautiful and everything that is beautiful is good. Though the good and the beautiful are coextensive, there is evidence that they are not identical. In the second part of the paper I show significance of this relation. In ethics it implies that the good is (...) the right. It also allows one to see how platonists can believe that goodness exists in mathematics. And it explains the usefulness of mathematics in moral education. (shrink)

This article discusses two coextensive concepts of logical consequence that are implicit in the two fundamental logical practices of establishing validity and invalidity for premise-conclusion arguments. The premises and conclusion of an argument have information content (they ?say? something), and they have subject matter (they are ?about? something). The asymmetry between establishing validity and establishing invalidity has long been noted: validity is established through an information-processing procedure exhibiting a step-by-step deduction of the conclusion from the premise-set. Invalidity is established (...) by exhibiting a countermodel satisfying the premises but not the conclusion. The process of establishing validity focuses on information content; the process of establishing invalidity focuses on subject matter. Corcoran's information-theoretic concept of logical consequence corresponds to the former. Tarski's model-theoretic concept of logical consequence formulated in his famous 1936 no-countermodels definition corresponds to the latter. Both are found to be indispensable for understanding the rationale of the deductive method and each complements the other. This study discusses the ontic question of the nature of logical consequence and the epistemic question of the human capabilities presupposed by practical applications of these two concepts as they make validity and invalidity accessible to human knowledge.

Une violence généralisée semble coextensive à la mondialisation. La question se pose de savoir quels « croisements » engendrent la régression du politique en deçà des formes qui ont fait l’historicité des siècles passés. Il faut remettre en question le préjugé marxien d’un « achèvement » de la critique du religieux pour affronter le régime de constitution des corps comme corps symboliques et comme corps productifs, soumis à une double expropriation.

In "Supervenience, Necessary Coextension, and Reducibility" (Philosophical Studies 49, 1986, 163-176), among other results, I showed that weak or ordinary supervenience is equivalent to Jaegwon Kim's strong supervenience, given certain assumptions: S4 modality, the usual modal conception of properties as class-concepts, and diagonal closure or resplicing of the set of base properties. This last means that any mapping of possible worlds into extensions of base properties counts itself as a base property. James Van Cleve attacks the modal conception of property (...) and diagonal closure. To me it seems desperate to reject diagonal closure merely in order to save supervenience-materialism. But I concede that it may be unacceptable in the context of a sparser theory of properties. (shrink)

Bioethics, Volume 36, Issue 4, Page 348-355, May 2022.

This three-part chapter explores a higher-order logic we call ‘Classicism’, which extends a minimal classical higher-order logic with further axioms which guarantee that provable coextensiveness is sufficient for identity. The first part presents several different ways of axiomatizing this theory and makes the case for its naturalness. The second part discusses two kinds of extensions of Classicism: some which take the view in the direction of coarseness of grain (whose endpoint is the maximally coarse-grained view that coextensiveness is sufficient for (...) identity), and some which take the view in the direction of fineness of grain (whose endpoint is the maximally fine-grained theory containing all distinctness claims compatible with Classicism). The third part introduces some techniques for constructing models of Classicism, and uses them to prove the consistency of many of the extensions of Classicism introduced in the second part.

I examine Aristotle’s definition of scientific knowledge in Posterior Analytics 71b 9-12 and try to understand how it relates to the sophistical way of knowing and to "kata sumbebekos knowledge". I claim that scientific knowledge of p requires knowing p by its appropriate cause, and that this appropriate cause is a universal (katholou) in the restricted sense Aristotle proposes in 73b 26-27 ff., i.e., an attribute coextensive with the subject (an extensional feature) and predicated of the subject in itself (...) (an intensional feature). Kata sumbebekos knowledge, on the other hand, can occur even when the predicate of a conclusion is coextensive with its subject and is proved by a convertible meson which is not the most appropriate from an explanatory standpoint.

An episiotomy is ‘an intrapartum procedure that involves an incision to enlarge the vaginal orifice,’1 and is primarily justified as a way to prevent higher degrees of perineal trauma or to facilitate a faster birth in cases of suspected fetal distress. Yet the effectiveness of episiotomies is controversial, and many professional bodies recommend against the routine use of episiotomies. In any case, unconsented episiotomies are alarmingly common, and some care providers in obstetric settings often fail to see consent as necessary (...) in context. In their article, ‘The ethics of consent during labour and birth: episiotomies,’ van der Pijl et al reiterate that consent is necessary for episiotomies. They specify, further, that the antenatal period is crucial for exchanging information, establishing trust between the birthing subject and provider, and exploring the birthing subject’s—rather than the care provider’s—values and preferences regarding episiotomies. They recommend an individualised approach, which would enable birthing subjects to choose how and when they want to give consent. I applaud van der Pijl et al on their practicable recommendations regarding consent for episiotomies. This is certainly a step in the right direction where respect for birthing subjects’ bodily autonomy and integrity is concerned. Still, we must be reminded that consent alone is not coextensive with autonomy. The conditions for securing informed consent in healthcare does not guarantee that one’s decision is truly reflective of their values. After all, even valid consent does not rule out ‘normatively significant external influence’.2 Consent acquisition for obstetric procedures present no …. (shrink)

This paper identifies the phenomenon of conceptual competence injustice, a form of epistemic injustice that occurs when a marginalized epistemic agent makes a conceptual claim and is illegitimately regarded as having failed to grasp one or more of the concepts expressed in her testimony. The notion of a conceptual claim is given a deflationary account that is coextensive with the class of a priori knowable claims. This study reveals a form of oppression that severely hinders marginalized epistemic agents who (...) seek to create or communicate conceptual knowledge. Conceptual competence injustice is compared and contrasted with three other forms of epistemic injustice: testimonial injustice, hermeneutical injustice, and contributory injustice. The final section investigates a number of damaging effects that conceptual competence injustice has on marginalized persons pursuing a career in academic philosophy. (shrink)

Ethical reality is coextensive with human dignity. Therefore, one essential way to understand ethics is as the systematic effort to discern the imperatives of human dignity. Seeing ethics in this way highlights the fact that health care institutions have many centers of ethical responsibility (CERs) — the Chief Executive Officer, Board of Trustees, senior management team, etc. The Ethics Committee is only one such CER and not the most important one. These other CERs will benefit from identifying: (1) the (...) fact that they are consistently dealing with ethical reality and making ethical decisions; (2) some critical elements of good ethical decision-making: (i) having the appropriate community; (ii) making the guiding value priorities explicit and specific; (iii) gaining skill in using the needed intellectual tools; and (iv) fashioning appropriate process and structure for discernment.

The article is a reappraisal of the requirement of maximal specificity (RMS) proposed by the author as a means of avoiding "ambiguity" in probabilistic explanation. The author argues that RMS is not, as he had held in one earlier publication, a rough substitute for the requirement of total evidence, but is independent of it and has quite a different rationale. A group of recent objections to RMS is answered by stressing that the statistical generalizations invoked in probabilistic explanations must be (...) lawlike, and by arguing that predicates fit for occurrence in lawlike statistical probability statements must meet two conditions, at least one of which is violated in each of the counterexamples adduced in the objections. These considerations suggest the conception that probabilistic-statistical laws concern the long-run frequency of some characteristic within a reference class as characterized by some particular "description" or predicate expression, and that replacement of such a description by a coextensive one may turn a statement that is lawlike into another that is not. Finally, to repair a defect noted by Grandy, the author's earlier formulation of RMS is replaced by a modified version. (shrink)

Priority monism is roughly the view that the universe is the only fundamental object, that is, a concrete object that does not depend on any other concrete object. Schaffer, the main advocate of PM, claims that PM is compatible with dependence having two different directions: from parts to wholes for subcosmic wholes, and from whole to parts for the cosmic whole. Recently it has been argued that this position is untenable. Given plausible assumptions about dependence, PM entails that dependence has (...) only one direction, it always goes from wholes to parts. One such plausible assumption is a principle of Isolation. I argue that, given all extant accounts of dependence on the market, PM entails No Isolation. The argument depends upon a particular feature of the dependence relation, namely, necessitation and its direction. In the light of this, I contend that the argument is important, insofar as it suggests that we should distinguish dependence from other cognate notions, e.g. grounding. Once this distinction is made, I suggest we should also distinguish between two different notions of fundamentality that might turn out to be not-coextensive. (shrink)

This paper rehabilitates the Stoic conception of blending from the ground up, by freeing the Stoic conception of body from three interpretive presuppositions. First, the twin hylomorphic presuppositions that where there is body there is matter, and that where there is reason or quality there is an incorporeal. Then, the atomistic presupposition that body is absolutely full and rigid, and the attendant notion that resistance (antitupia) must be ricochet. I argue that once we clear away these presuppositions about body, the (...) foundations of Stoic corporealism fall into place. Body is fundamental (not hylomorphic). The two fundamental principles (archai) are bodies: divine active reason (logos) and passive matter (hulē); and these two bodies are two, not matter and form all over again, nor actual and potential, but agent and patient. The independence of the two archai is no threat to the unity of the cosmos, however, because the Stoic theory of body allows for the complete coextension of the archai. The hylomorphic thinker rightly asks, what relation could be tighter than that of the wax and its shape? The Stoic replies: a causal relation, the interaction of agent and patient completely coextended in a through and through blend. (shrink)

This collection of five essays by Germany’s most prominent and influential social thinker both links Luhmann’s social theory to the question “What is modern about modernity?” and shows the origins and context of his theory. In the introductory essay, “Modernity in Contemporary Society,” Luhmann develops the thesis that the modern epistemological situation can be seen as the consequence of a radical change in social macrostructures that he calls “social differentiation,” thereby designating the juxtaposition of and interaction between a growing number (...) of social subsystems without any hierarchical structure. “European Rationality” defines rationality as the capacity to see the difference between systems and their environment as a unity. Luhmann argues that, in a world characterized by contingency, rationality tends to become coextensive with imagination, a view that challenges their classical binary opposition and opens up the possibility of seeing modern rationality as a paradox. In the third essay, “Contingency as Modern Society’s Defining Attribute,” Luhmann develops a further and probably even more important paradox: that the generalization of contingency or cognitive uncertainty is precisely what provides stability within modern societies. In the process, he argues that medieval and early modern theology can be seen as a “preadaptive advance” through which Western thinking prepared itself for the modern epistemological situation. In “Describing the Future,” Luhmann claims that neither the traditional hope of learning from history nor the complementary hope of cognitively anticipating the future can be maintained, and that the classical concept of the future should be replaced by the notion of risk, defined as juxtaposing the expectation of realizing certain projects and the awareness that such projects might fail. The book concludes with “The Ecology of Ignorance,” in which Luhmann outlines prospective research areas “for sponsors who have yet to be identified.”. (shrink)

The ArugmentThis essay answers a single question: what was Robert Hooke, the Royal Society's curator of experiments, doing in his well-known 1665 work,Micrographia?Hooke was articulating a “universal cure of the mind” capable of bringing about a “reformation in Philosophy,” a change in philosophy's interpretive practices and organization. The work explicated the interpretive and political foundations for a community of optical instrument users coextensive with the struggling Royal Society. Standard observational practices would overcome the problem of using nonstandard instruments, while (...) inherent inrepresentation– the interpretive practice championed in the text – were important theological and political meanings. Hooke's kind of experimental philosophy undermined the claims made by “atheists” and “enthusiasts” – the enemies of the restored church and state – while also producing useful knowledge. Equally important, Hooke modeled the community described inMicrographiaupon the classicalres publica, but his community made important concessions to Restoration political realities, especially the growing role of commercial or transactional relationships.

Scott Soames’ Reference and Description contains arguments against a number of different versions of two-dimensional semantics. After early chapters on descriptivism and on Kripke’s anti-descriptivist arguments, a chapter each is devoted to the roots of twodimensionalism in “slips, errors, or misleading suggestions” by Kripke and Kaplan, and to the two-dimensional approaches developed by Stalnaker (1978) and by Davies and Humberstone (1981). The bulk of the book (about 200 pages) is devoted to “ambitious twodimensionalism”, attributed to Frank Jackson, David Lewis, and (...) me. After a quick overview of two-dimensional approaches, I will focus on Soames’ discussion of ambitious twodimensionalism. I will then turn to a system advocated by Soames that is itself strikingly reminiscent of a two-dimensional approach. Two-dimensional semantic theories are varieties of possible-worlds semantics on which linguistic items can be evaluated relative to possibilities in two different ways, yielding two sorts of intensional semantic values, which can be seen as two “dimensions” of meaning. The second dimension is the familiar sort of Kripkean evaluation in metaphysically possible worlds, so that necessarily coextensive terms (such as ‘Hesperus’ and ‘Phosphorus’ or ‘water’ and ‘H2O’) always have the same semantic value. The first dimension behaves differently, so that there are typically at least some cases where necessarily coextensive terms have different semantic values on the first dimension. For this reason, the two-dimensional framework is sometimes seen as a way of granting many of the insights of a Kripkean approach to meaning (on the second dimension), while retaining elements of a Fregean approach to meaning (on the first dimension).

In the spirit of B. C. van Fraassen's view of science called Constructive Empiricism, we propose a scientific criterion to decide whether a concrete object is observable, as well as a coextensive scientific-philosophical definition of observability, and we sketch a rigorous account of modal language occurring in science. We claim that our account of observability solves three problems to which current accounts of observability, notably van Fraassen's own accounts, give rise. We further claim that our account of modal propositions (...) (subjunctive conditionals included), which proceeds wholly within the framework of the semantic view on scientific theories, grounds his claim that such an account is possible without relying on ‘inflationary metaphysics’, notably without postulating an infinitude of different universes besides the universe we inhabit. We thus claim to solve a fourth problem: how to give a precise nominalist account of modal language in science tailor-made for Constructive Empiricism.

I will be arguing that a subject’s belief that p is justified if and only if he knows that p: justification is knowledge. I will start by describing two broad classes of allegedly justified beliefs that do not constitute knowledge and which, hence, cannot be what they are often taken to be if my view is correct. It is far from clear what my view is until I say a lot more about the relevant concept or concepts of justification that (...) concern me. The following section describes several concepts of justification that epistemologists have employed, and, in particular, identifies the two concepts of justification that I claim are coextensive with the concept of knowledge. One of those is the deontological conception of justification: I will be arguing that one ought not believe that p unless one knows that p. I imagine that the major opposition to my view will be that it is simply obvious that there are justified false beliefs, a feeling that I try to dispel in the lengthy section on concepts of justification before I finally get around to giving the main arguments in favor of my view. A view as unorthodox as mine demands more than a single argument: I offer four in the third section. Everyone allows that many people have many unjustified beliefs, and everyone has some unjustified beliefs, but such beliefs appear to be far more prevalent on my view than on more orthodox views. In the last section, I argue that unjustified beliefs, although widespread, are not quite as common as they might appear to be on my view. (shrink)

_Conservative Reductionism_ sets out a new theory of the relationship between physics and the special sciences within the framework of functionalism. It argues that it is wrong-headed to conceive an opposition between functional and physical properties and to build an anti-reductionist argument on multiple realization. By contrast, all properties that there are in the world, including the physical ones, are functional properties in the sense of being causal properties, and all true descriptions that the special sciences propose can in principle (...) be reduced to physical descriptions by means of functional reduction, despite multiple realization. The book develops arguments for from the metaphysics of properties and the philosophy of physics. These arguments lead to a conservative ontological reductionism. It then develops functional reduction into a fully-fledged, conservative theory reduction by means of introducing functional sub-types that are coextensive with physical types, illustrating that conservative reductionism by means of case studies from biology.

Yitzhak Melamed here offers a new and systematic interpretation of the core of Spinoza's metaphysics. In the first part of the book, he proposes a new reading of the metaphysics of substance in Spinoza: he argues that for Spinoza modes both inhere in and are predicated of God. Using extensive textual evidence, he shows that Spinoza considered modes to be God's propria. He goes on to clarify Spinoza's understanding of infinity, mereological relations, infinite modes, and the flow of finite things (...) from God's essence. In the second part of the book, Melamed relies on this interpretation of the substance-mode relation and the nature of infinite modes and puts forward two interrelated theses about the structure of the attribute of Thought and its overarching role in Spinoza's metaphysics. First, he shows that Spinoza had not one, but two independent doctrines of parallelism. Then, in his final main thesis, Melamed argues that, for Spinoza, ideas have a multifaceted structure that allows one and the same idea to represent the infinitely many modes which are parallel to it in the infinitely many attributes. Thought turns out to be coextensive with the whole of nature. Spinoza cannot embrace an idealist reduction of Extension to Thought because of his commitment to the conceptual separation of the attributes. Yet, within Spinoza's metaphysics, Thought clearly has primacy over the other attributes insofar as it is the only attribute which is as elaborate, as complex, and, in some senses, as powerful as God.

Suppose we believe that a property F is coextensive with moral permissibility. F may be, for example, the property of having the best consequences, if we are Consequentialists, or that of conforming to a universalisable maxim, if we are Kantians, and so on. This may raise the following problem. It is plausible that permissibility is “closed under implication”: any act that is implied by a permissible act must itself be permissible. Yet, in some cases, F might not be closed (...) under implication. If that is so, then F cannot be coextensive with permissibility. Maximalism has been proposed as a solution to this problem. A “maximal” act is one not implied by any other act. Maximalism restricts the claim that F is coextensive with permissibility to maximal acts only. A non-maximal act may be permissible without being F if it is implied by a maximal act that is F. The general aim of this paper is to investigate these issues by considering the formal structure of acts, or the “act-implication” relation. Discussions of Maximalism have tended to assume implicitly that acts have structure of some sort, but there has been little careful attention given to this structure. I aim to show that, by thinking about structure, we can provide a stronger defence of Maximalism. (shrink)

The paper sets out a new strategy for theory reduction by means of functional sub-types. This strategy is intended to get around the multiple realization objection. We use Kim's argument for token identity (ontological reductionism) based on the causal exclusion problem as starting point. We then extend ontological reductionism to epistemological reductionism (theory reduction). We show how one can distinguish within any functional type between functional sub-types. Each of these sub-types is coextensive with one type of realizer. By this (...) means, a conservative theory reduction is in principle possible, despite multiple realization. We link this account with Nagelian reduction, as well as with Kim's functional reduction. (shrink)

The 2013 Ebola virus outbreak in West Africa, as of writing, is declining in reported human cases and mortalities. The resulting devastation caused highlights how health systems, in particular in West Africa, and in terms of global pandemic planning, are ill prepared to react to zoonotic pathogens. In this paper we propose One Health as a strategy to prevent zoonotic outbreaks as a shared goal: that human and Great Ape vaccine trials could benefit both species. Only recently have two phase (...) 2/3 Ebola human vaccine trials been started in West Africa. This paper argues for a conceptual change in pandemic preparedness. We first discuss the ethics of One Health. Next, we focus on the current Ebola outbreak and defines its victims. Third, we present the notion of a ‘shared benefit’ approach, grounded in One Health, and argue for the vaccination of wild apes in order to protect both apes and humans. We believe that a creation of such inter-species immunity is an exemplar of One Health, and that it is worth pursuing as a coextensive public health approach. (shrink)

Fodor (1990) argues that the theory of evolution by natural selection will not help to save naturalistic accounts of representation from the disjunction problem. This is because, he claims, the context 'was selected for representing things as F' is transparent to the substitution of predicates coextensive with F. But, I respond, from an evolutionary perspective representational contexts cannot be transparent: only under particular descriptions will a representational state appear as a "solution" to a selection "problem" and so be adaptive. (...) Only when we construe representational states as opaque in this manner are the generalizations of branches of evolutionary theory, like foraging theory, possible. (shrink)

In this paper, I claim that since there is a cognitively impenetrable stage of visual perception, namely early vision, and cognitive penetrability and theory-ladenness are coextensive, the CI of early vision entails that early vision content is theory neutral. This theory-neutral part undermines relativism. In this paper, I consider two objections against the thesis. The one adduces evidence from cases of rapid perceptual learning to undermine my thesis that early vision is CI. The other emphasizes that the early perceptual (...) system, in order to solve various underdetermination problems, relies on certain principles, which may be taken to constitute a sort of a theory about the world that affect early vision, rendering it theory-laden. Both objections purport to show that early vision is CP and theory-laden. Against this thesis, I argue that the evidence on which the two objections are based does not show that early vision is CP and is fully compatible with the view that early vision is CI. (shrink)

I discuss Aristotle’s views in Metaphysics VII-6 (Z-6) on the issue whether each thing is the same as its essence. I propose a deflationary interpretation according to which Z-6 develops a “logical approach” (logikos) in which “sameness” amounts only to coextensiveness between definiendum and definiens with no attention to more specific issues about ontological and explanatory features of definitions.

Wars are large-scale conflicts between organized groups of belligerents, which involve suffering, devastation, and brutality unlike almost anything else in human experience. Whatever one’s other beliefs about morality, all should agree that the horrors of war are all but unconscionable, and that warfare can be justified only if we have some compel- ling account of what is worth fighting for, which can justify contributing, as individu- als and as groups, to this calamitous endeavour. Although this question should obviously be central (...) to both philosophical and politi- cal discussion about war, it is at the forefront of neither. In recent years, philosophical discussion of warfare has bloomed, but the debate has focused on whom we may kill, on the assumption that our aims are justified.1 Political debate, meanwhile, is more concerned with matters of prudence, international law, and public justification, than with reassessing what is worth fighting for. For wars of intervention to halt or prevent massive humanitarian crises, this gap is not so troubling. When warfare is the only means to prevent the mass killing or enslavement of the innocent, the purposes of military force are clear enough (though undoubtedly many other problems remain). The problem is more pressing, how- ever, for the justification of national defence.3 Although common-sense morality and international law view national defence as the paradigm case of justified warfare, grounding this consensus is surprisingly difficult.4 We typically believe that any state is justified in using lethal force to protect its territory against any form of uninvited military incursion by any other state. And yet we lack a good argument to explain why this should be so. In this chapter, I explain why one familiar and otherwise plausible approach to the justification of killing in war cannot adequately ground common-sense views of permissible national defence.5 Reductionists believe that justified warfare reduces to an aggregation of acts that are justified under ordinary principles of interpersonal morality.6 The standard form of reductionism focuses on the principles governing killing in ordinary life, specifically those that justify intentional killing in self- and other-defence, and unintended but foreseen (for short, collateral) killing as a lesser evil. Justified warfare, on this view, is no more than the coextension of multiple acts justified under these two principles. Reductionism is the default philosophical approach to thinking through the ethics of killing in war. It makes perfect sense to ask what principles govern permissible kill- ing in general, before applying them to the particular context of war. If it cannot deliver a plausible set of conclusions about when national defence is permitted, then we must either revise our beliefs about which conclusions count as plausible, or else face the significant challenge of developing a different theoretical model for justifying war- fare—an exceptionalist model, which views war as an exception to the regular moral landscape, to which principles apply which apply to nothing else but war.7 We must show, in other words, that there is something worth fighting for in wars of national defence, which is not engaged when we use force in any other context. The chapter proceeds as follows. Section 2.2 sets out the argument against reduc- tionism.8 Section 2.3 considers and rebuts one common response to the argument, which has often been thought sufficient grounds to disregard its conclusion. Section 2.4 then asks whether a modified reductionism would survive unscathed by the argu- ment. Finally, section 2.5 sets out some desiderata on a plausible exceptionalist alterna- tive. Section 2.6 concludes. (shrink)

The Mohist School's logical study focuses mainly on the following inference rule: suppose that N and M are coextensive terms, or N a subset of M; it follows that if a verb can appear in front of N, it can also appear in front of M. That is, if 'VM' then 'VN', where V is some extensional verb. Such an approach to logical inference necessitates the study of logical relations among nouns, verbs, and the relations between these two types (...) of words. Evidence is offered here that the Mohists clearly distinguished extensional verbs from intensional verbs, and that this insight enabled them to say, among other things, that VN does not follow from VM, even in cases where N is M or contained in M, as long as the V in question is an intensional verb.

Resumo: O presente artigo versa sobre o problema político-filosófico do fascismo. O conceito tem mostrado crescente relevância no cenário público nacional e mundial, figurando cada vez mais no debate leigo e especializado. O termo fascismo, hoje, é amplamente empregado, tanto na qualificação de movimentos políticos de diversos espectros quanto na grande mídia e revistas científicas. O objetivo deste artigo é utilizar o conceito de transindividual na compreensão do fascismo, a partir da teorização, ela mesma transindividual, do fenômeno, realizada por Deleuze (...) e Guattari, através da sua compreensão do desejo. O transindividual caracteriza um movimento filosófico de dupla rejeição em que se nega, simultaneamente, uma abordagem holista e individualista do campo social, procurando pensar o indivíduo e coletivo como coextensivos a um processo genético que produz a ambos, sem primado de um sobre o outro. Tal conceito vem se revelando uma ferramenta analítica de crescente uso e repercussão, no debate acadêmico contemporâneo. Nesse sentido, a utilização do transindividual, enquanto matriz teórica, na compreensão do fenômeno fascista ainda não foi realizada de forma esquemática e, desse modo, recorrendo à compreensão transindividual do fascismo de Deleuze e Guattari, pretende-se contribuir para o alargamento desse horizonte teórico.: This paper is directed towards the political and philosophical problem of fascism. This concept is manifesting increasingly relevance in the national and global public scenario, widely appearing in the specialized and lay debate. The term ‘’fascism”, today, is largely used in the qualification of movements from diverse shades of the political spectrum and in the mainstream media and scientific journals. The goal of this paper is the application of the concept of the transindividual to the fascist phenomena through Deleuze and Guattar theory of the fascist desire, in itself, a transindividual one. The transindividual marks a philosophical movement of a double rejection against an holistic approach to the social dimension as well as and individualist one, aiming to think both dimensions as coextensive to a genetic process that produces both of them, without any priority regarding any dimension in relation to the other. This concept has been revealing itself as an increasingly useful analytical tool in the contemporary academic debate. In this sense, the use of the concept of transindividuality as the theoretical framework in the philosophical understanding of the phenomenon of fascism has not been yet realized in a schematic way. Applying the concept of fascism of Deleuze and Guatttari in a transindividual framework, we intend to contribute to the development of this theoretical approach. (shrink)

The naive theory of properties states that for every condition there is a property instantiated by exactly the things which satisfy that condition. The naive theory of properties is inconsistent in classical logic, but there are many ways to obtain consistent naive theories of properties in nonclassical logics. The naive theory of classes adds to the naive theory of properties an extensionality rule or axiom, which states roughly that if two classes have exactly the same members, they are identical. In (...) this paper we examine the prospects for obtaining a satisfactory naive theory of classes. We start from a result by Ross Brady, which demonstrates the consistency of something resembling a naive theory of classes. We generalize Brady’s result somewhat and extend it to a recent system developed by Andrew Bacon. All of the theories we prove consistent contain an extensionality rule or axiom. But we argue that given the background logics, the relevant extensionality principles are too weak. For example, in some of these theories, there are universal classes which are not declared coextensive. We elucidate some very modest demands on extensionality, designed to rule out this kind of pathology. But we close by proving that even these modest demands cannot be jointly satisfied. In light of this new impossibility result, the prospects for a naive theory of classes are bleak. (shrink)

Essentially everyone agrees that the outlawing of slavery, or the beginning of women’s suffrage, or the defeat of Nazism constitute paradigmatic examples of moral progress in human history. But this consensus belies a deep division about the nature of moral progress more generally, a consequence of the foundational differences among and within normative traditions regarding the nature and scope of the ‘moral’ in moral progress. This essay proposes that philosophers might nonetheless converge on a working definition of moral progress by (...) identifying a proxy property that reliably tracks moral progress, but which does not purport to be coextensive with the philosophically-relevant property. The aim of this essay is to identify this proxy property with emerging empirical measures of population welfare, and to show why this indicator of moral progress can garner overlapping consensus from a variety of normative traditions.
