What is the connection between dispositions and ethics? Some might think very little and those who are interested in dispositions tend to be metaphysicians whose interests are far from value. However, we argue in this paper that dispositions and dispositionality are central to ethics, indeed a precondition. Ethics rests on a number of notions that are either dispositional in nature or involve real dispositions or powers at work. We argue for a dispositional account of value that offers an alternative to (...) the traditional fact-value dichotomy. We explain the place of value within a structure that explains the possibility of ethics. Elsewhere in this structure, we argue that moral responsibility is a precondition for ethics and that it is a dispositional notion depending critically on what Mumford and Anjum have called the dispositional modality. Moral responsibility in turn depends on there being both agency and normativity. We argue that intentionality and agency are preconditions for agency and that value is a precondition of normativity. All these notions are dispositional and make best sense if there are real dispositions or causal powers of agents. (shrink)
The hole argument concludes that substantivalism about spacetime entails the radical indeterminism of the general theory of relativity (GR). In this paper, I amend and defend a response to the hole argument first proposed by Butterfield (1989) that relies on the idea of counterpart substantivalism. My amendment clarifies and develops the metaphysical presuppositions of counterpart substantivalism and its relation to various definitions of determinism. My defence consists of two claims. First, contra Weatherall (2018) and others: the hole argument is not (...) a blunder resulting from a mistaken view on how mathematical physics works, and requires a developed (meta)metaphysical response. Second, contra Melia (1999) and others: one can be content with a notion of determinism for GR which is not sensitive to merely haecceitistic differences. (shrink)
The dispute over the exact nature and status of possible worlds in Leibniz’s philosophy has proven difficult to resolve. The standard view, that there is one unique actual world and that possible worlds exist solely as ideas within God’s understanding, sits in tension with important metaphysical and theological components of Leibniz’s system. For example, Leibniz takes possible individuals to have some “essence or reality” in themselves and to strive for existence, which allows him to ground counterfactual claims and to overcome (...) necessitarianism. However, scholars have long seen these claims as being at odds with God’s creation of one unique actual world. Catherine Wilson (2000) challenges the standard view’s claim that possible worlds are substantially different from the actual world, arguing instead that Leibniz’s metaphysical commitments are consistent with there being more than one actual world and that Leibniz has no way to block the claim that God would generate more than one such world. In this paper, I expand on Wilson’s account and argue, contrary to the standard view, that the key theses at the heart of Leibniz’s philosophical system entail modal realism—for Leibniz, there can be no ontological difference between possible and actual worlds.

Essentialists hold that at least a certain range of entities can be meaningfully said to have natures, essences, or essential features independently of how these entities are described, conceptualized or otherwise placed with respect to our specifically human interests, purposes or activities. Modalists about essence, on the one hand, take the position that the essential truths are a subset of the necessary truths and the essential properties of entities are included among their necessary properties. Non-modalists about essence, on the other (...) hand, oppose the reduction of essence to modality and hold, rather, that essence is more basic than, and explanatory of, modality. This chapter begins with a brief summary of Kit Fine’s well-known challenges to the modal account of essence and considers a recent attempt by “sparse modalists” like Sam Cowling and Nathan Wildman to respond to Fine’s counterexamples by adding a sparseness constraint to the “bare” modal account of essence. A further question arises, however, as to whether and how Fine’s definitional approach can avoid his own counterexamples against the modal approach to essence. The chapter concludes with some final thoughts concerning the theoretical roles ascribed to essence by modalists and non-modalists. (shrink)
This paper provides an overview of the history of the notion of essence in 20th century analytic philosophy, focusing on views held by influential analytic philosophers who discussed, or relied on essence or cognate notions in their works. It in particular covers Russell and Moore’s different approaches to essence before and after breaking with British idealism, the (pre- and post-)logical positivists’ critique of metaphysics and rejection of essence (Wittgenstein, Carnap, Schlick, Stebbing), the tendency to loosen the notion of logical necessity (...) to accommodate certain metaphysical truths in Wittgenstein and others, Quine’s logical rehabilitation of metaphysics and criticism of de re modality, the modal view of essence promoted by the development of quantified modal logic (C. I. Lewis, Barcan Marcus, Kripke) and direct reference theory (Barcan Marcus, Kripke, Putnam), and the emergence of the notion of metaphysical necessity (Kneale, Kripke), and finally Fine’s re-establishment of a Neo-Aristotelian, hyperintensional notion of essence in contemporary metaphysics.

Jeremy Fix, in ‘Two Sorts of Constitutivism’ (2021), makes a case for the possibility of contingent essential properties to account for the metaphysical status of constitutive standards of things. In this brief note, I will present an open problem affecting Fix's conception, namely, the explanation of the membership of particulars to a genus, which is necessary to identify particulars subject to standards.
In this paper a generalized account of relevance as difference-making is developed. It is argued that relevance should not be considered as a particular relation, but as a (higher-order) property of instances of arbitrary relations: namely the property that variations of the relata of the relation instance make a difference for its truth. This generalized account of relevance can be fruitfully applied in many domains, such as (i) logical reasoning with applications to explanation, confirmation, verisimilitude, is-ought inference, (ii) probabilistic reasoning (...) with applications to explanation and confirmation, (iii) nomological and causal implication, (iv) communication, (v) grounding and (vi) essentiality. In conclusion, difference-making relevance is a highly unifying and fruitful philosophical concept. (shrink)
Leibniz claims that for every possible substance S there is an individual concept that includes predicates describing everything that will ever happen to S, if S existed. Many commentators have thought that this leads Leibniz to think that all properties are had essentially, and thus that it is not metaphysically possible for substances to be otherwise than the way their individual concept has them as being. I argue against this common way of reading Leibniz’s views on the metaphysics of modality. (...) I develop a model in which individual concepts are innocent; that is, individual concepts are divine ideas that permit God to know everything that will ever happen to all possible substances, if created, but these individual concepts neither require that all properties are had essentially nor require that it is metaphysically necessary for substances to be the way their individual concepts have them as being.

L.A. Paul calls “deep” the kind of essentialism according to which the essential properties of objects are determined independently of the context. Deep essentialism opposes “shallow essentialism”, of which David Lewis is said to be a prominent advocate. Paul argues that standard forms of deep essentialism face a range of issues (mainly based on an interpretation of Quinean skepticism) that shallow essentialism does not. However, Paul claims, shallow essentialism eliminates the very heart of what motivates essentialism, so it is better (...) to be deep than shallow. Accordingly, she proposes a very sharp novel account of essentialism, which, while attempting to preserve some of the advantages of shallow essentialism over the classical forms of deep essentialism, can be deemed to be deep. In this paper, I compare Paul’s proposal for a kind of deep essentialism with Lewis’s account, as it is presented by Paul. My aim is to show that the differences between the two approaches are not as significant as Paul takes them to be, and that Paul’s account can be taken to be deeper than Lewis’s only at the cost of sacrificing the very idea at the bottom of deep essentialism. This might be taken to suggest that, if Paul is correct in asserting that shallow essentialism is better equipped to address some skeptical challenges, but it is generally preferable to be deep than shallow, then Lewis’s account should be re-evaluated, since, as shallow as it can be, it might be deeper than it looks.

A simplified variant of Gödel’s ontological argument is presented. The simplified argument is valid already in basic modal logics K or KT, it does not suffer from modal collapse, and it avoids the rather complex predicates of essence (Ess.) and necessary existence (NE) as used by Gödel. The variant presented has been obtained as a side result of a series of theory simplification experiments conducted in interaction with a modern proof assistant system. The starting point for these experiments was the (...) computer encoding of Gödel’s argument, and then automated reasoning techniques were systematically applied to arrive at the simplified variant presented. The presented work thus exemplifies a fruitful human-computer interaction in computational metaphysics. Whether the presented result increases or decreases the attractiveness and persuasiveness of the ontological argument is a question I would like to pass on to philosophy and theology. (shrink)
Two seventeeth-century Scottish Catholic philosophers, Robert Balfour and William Chalmers, are introduced and their accounts of the metaphysics of the Eucharist are discussed. Their ideas are largely in terms of the Aristotelian concepts of substance, accident and inherence, with special attention paid to the idea that the essence of an accident is not its actual inherence (that is, its act of inhering) in a substance but its aptness for inherence in a substance. Balfour appears to accept this (Thomist) doctrine. But (...) Chalmers has a different story to tell. He holds that the essence of an accident is not its actual inherence or its power to inhere (which includes its aptness for inherence), but instead belongs to what he terms the ‘root and basis’ of that power. I speculate briefly about a possible Scotistic interpretation of his words. (shrink)
Formalizations in first-order logic are standardly used to represent logical forms of sentences and to show the validity of ordinary-language arguments. Since every sentence admits of a variety of formalizations, a challenge arises: why should one valid formalization suffice to show validity even if there are other, invalid, formalizations? This paper suggests an explanation with reference to criteria of adequacy which ensure that formalizations are related in a hierarchy of more or less specific formalizations. This proposal is then compared with (...) stronger criteria and assumptions, especially the idea that sentences essentially have just one logical form. (shrink)
Fairchild (2019) advertised the humility of material plenitude, arguing that despite the profligate ontology of coincident objects it entails, the best version of plenitude is one that takes no stand on a range of nearby questions about modality and coincidence. Roughly, the thought is that plenitude says only that there are coincident objects corresponding to every consistent pattern of essential and accidental properties. Plenitude says (or should say) nothing about which patterns those might be, and so should be compatible with (...) any reasonable hypothesis about which combinations of properties it is possible for something to have. I argued in the earlier paper that a particular formulation of the target view (Global Plenitude) has exactly that virtue. But, unfortunately, Global Plenitude turns out not to be very humble at all. Global Plenitude is incompatible with an exceptionally compelling hypothesis about coincidence: that there are some things which coincide, but might not have. Scandal ensues. (shrink)
The concept of essence holds a pivotal role in unraveling Aristotle’s metaphysical framework. In his exploration of Metaphysics, Aristotle delves into the quest for fundamental being, positing that the primary substance is essentially synonymous with essence. This paper examines the criteria for essence, drawing from both the Categories and Metaphysics Z. Two distinct perspectives on essentialism, namely individual essentialism, aligned with the contemporary modal account of essence, and kind essentialism, are scrutinized. Through a critical analysis, this paper contends that both (...) these essentialist accounts fall short in adequately elucidating the Aristotelian concept of essence. Consequently, this pivotal notion, governed by Aristotelian criteria, remains a perplexing enigma, challenging contemporary attempts to fully grasp its intricacies. (shrink)
This paper reconsiders Leibniz’s conception of the nature of possible things and offers a novel interpretation of the actualization of possible substances. This requires analyzing a largely neglected notion, the reality of individual essences. Thus far scholars have tended to construe essences as representational items in God’s intellect. We acknowledge that finite essences have being in the divine intellect but insist that they are also grounded in the infinite essence of God, as limitations of it. Indeed, we show that it (...) is critical to understand that this dependence on God’s essence is prior to the dependence on God through divine ideas. Here it is crucial to distinguish questions concerning the ontological status of essences from questions concerning their reality. This yields a fresh view of Leibniz’s theory of creation, which takes seriously his claim that the same thing is first a mere possibility but after creation an actually existent substance. (shrink)
It is common to argue that something x is distinct from something y by pointing out that x and y do not share all their essential properties. I show that arguments of this type are unsound. This unsoundness is rooted in the fact that sentences of the form ‘x is essentially F’ are ambiguous. Under one reading, the sentence says of x that it has a property of a unique and special kind. Interpreted in that way, the sentence is false, (...) for there are no such properties. Under another reading, the sentence says of x that it has a property and adds that this property is essential to x. Interpreted in that way, the sentence may be true but it does not allow to reach the desired conclusion that x is distinct from y. Thus, if someone argues that x is distinct from y by pointing out that x and y differ in essential properties, they face the following dilemma: either one of the argument’s premises implies the existence of the special property and it is false, or none of the premises implies the existence of the special property and the argument is invalid.

Essences play a central role in Spinoza’s philosophy, not only in his metaphysics, but also in his philosophy of mind, his theory of affects, and his political philosophy. Despite their importance, however, it is surprisingly difficult to determine what exactly essences are for Spinoza. On a widespread reading, the essence of X is nothing but the concept of X. This paper argues against this identification of essences and concepts. Spinozistic concepts are maximally inclusive: the concept of X contains everything that (...) is needed to make X conceivable. The essence of X, in contrast, is more limited in scope and does not include everything that is needed to make X conceivable. Thus, Spinoza avoids the ‘overloading’ of essences and the problems that would ensue. The account developed in this paper has a surprising implication, namely that the essences of non-divine, singular things do not suffice to render these things fully conceivable on Spinoza’s view. Thus, Spinoza breaks with a tradition according to which the essence of a thing states ‘what the thing is.’ As a result, his conception of essence is much further removed from traditional Aristotelian accounts, and from other seventeenth-century accounts, than usually acknowledged.

An important concern sometimes voiced in the neuroethical literature is that swift and radical changes to the parts of a person’s mental life essential for sustaining his/her numerical identity can result in the person ceasing to exist—in other words, that these changes may disrupt psychological continuity. Taking neurointerventions used for rehabilitative purposes as a point of departure, this short paper argues that the same radical alterations of criminal offenders’ psychological features which under certain conditions would result in a disruption of (...) numerical identity can be achieved without these having any effect on numerical identity. Thus, someone interested in making radical alterations to offenders’ psychology can avoid the charge that this would kill the offenders, while still achieving a radical transformation of them. The paper suggests that this possibility makes the question of what kinds of qualitive alterations to offenders’ identity are morally permissible pressing, but then briefly highlights some challenges for arguments against making radical qualitative identity alterations to offenders. No data are available. (shrink)
Spinoza claims that a person’s mind and body are one and the same. But he also claims that minds think and do not move, whereas bodies move and do not think. How can we reconcile these claims? I believe that Spinoza is building on a traditional view about identity over time. According to this view, identity over time is linked to essence, so that a thing that is now resting is identical to a thing that was previously moving, provided that (...) they share the same essence. I believe that Spinoza has a similar view about the identity of minds and bodies. In particular, a thing that is thinking in the attribute of thought is identical to a thing that is moving in the attribute of extension, provided that they share the same essence. (shrink)
Rawls famously argued against meritocratic conceptions of distributive justice on the grounds that the accumulation of merit is an unavoidably lucky process, both because of differences in early environment, and innate talents. Thomas Mulligan (2018a) has recently provided a novel defense of meritocracy against the “luck objection”, arguing that both sources of luck would be mostly eliminated in a meritocracy. While a system of fair equality of opportunity ensures that differences in social class or early environment do not lead to (...) differences in the accumulation of merit, Kripke’s essentiality of origin thesis means that our genetic endowments, and thus our innate talents, could not have been any other way. But if we could not fail to have our innate talents, Mulligan argues, then it is not a matter of luck that we have them, and so the merits we accumulate on their basis are not so luck-dependent. This paper argues that Mulligan’s appeal to the essentiality of origin thesis fails to rescue meritocratic conceptions of distributive justice from the luck objection for two reasons. First, even granting essentiality of origin and fair equality of opportunity, the contingencies of the market and the social environment mean that having some innate talents is far luckier than having others. And second, the appeal to essentiality of origin misses the underlying motivation for the luck objection, and ignores the intimate connection between desert and responsibility. (shrink)
Machine learning and essentialism have been connected in the past by various researchers, in order to state that the main paradigm in machine learning processes is equivalent to choosing the “essential” attributes for the machine to search for. Our goal in this paper is to show that there are connections between machine learning and essentialism, but only for some kinds of machine learning, and often not including deep learning methods. Similarity-based approaches, more connected to the overall prototype theory, spanning from (...) psychology and linguistics, seem more suited for pattern recognition and complex deep-learning issues, while for classification problems, mostly for unsupervised learning, essentialism seems like the best choice. In order to illustrate the difference better, we will connect both paths to their sources in other disciplines and see how human psychology influences our decision in machine-learning modeling as well. This leads to a philosophically very interesting consequence: even in the setting of supervised machine learning, essences are not present in data, but in targets, which in turn means that the categories which purport to be essences are in fact human-made, and hand-coded in the targets. The success of machine learning, therefore, does not give any substantial evidence for the independent existence of essential properties. Our stance here is to state that neither the existence nor the lack of “essential” properties in machine learning can lead to metaphysical, i.e., ontological claims. (shrink)
Dispositional realism, as we shall use the term, is a non-reductive, anti-Humean approach to dispositions which says that natural properties confer certain dispositions as a matter of metaphysical necessity. A strong form of dispositional realism is known as pan-dispositionalism, which is typically interpreted as the view that all natural properties are identical with, or essentially dependent on, dispositions. One of the most serious problems facing pan-dispositionalism is the conceivability objection, and the solution commonly offered by essentialists employs the so-called redescription (...) strategy. In this paper I argue that this orthodox strategy fails in certain cases. This argument, in turn, shows that essentialist forms of dispositional realism are implausible. The discussion points us towards an improved version of dispositional realism. According to this new version, natural properties are not essentially dispositional but necessarily ground dispositions.

It is not a coincidence that every red rose is coloured. No rose can be red without being coloured. A red rose is coloured in virtue of its being red, its being coloured is metaphysically explained by its being red. This is, at least in part, underwritten by what it is for the rose to be coloured, by the nature – or essence – of its being coloured. If this is right, then questions concerning possibility and necessity, questions concerning metaphysical (...) explanation, and questions concerning essence are systematically connected. This book proposes a unified account of metaphysical modality, grounding, and essence. It develops a semantic way to model essences as localised necessities that rule out worlds as impossible and uses it to account for grounding and metaphysical modality. (shrink)
Strong dispositional monism, the position that all fundamental physical properties consist in dispositional relations to other properties, is naturally construed as property structuralism. J. Lowe’s circularity/regress objection constitutes a serious challenge to SDM that questions the possibility of a purely relational determination of all property essences. The supervenience thesis of A. Bird’s graph-theoretic asymmetry reply to CRO can be rigorously proved. Yet the reply fails metaphysically, because it reveals neither a metaphysical determination of identities on a purely relational basis nor (...) a determination specifically of identities in the sense of essences. Asymmetry is thus not by itself sufficient for a solution to CRO. But it cannot even help to answer CRO when a model for the determination of essences is taken as a basis. Nor is asymmetry necessary for a reply, as property structures may well be symmetric. A metaphysics of dispositional properties as grounded in a purely relational structure faces serious obstacles, and the properties would not be fundamental. Since essence and grounding are notions of metaphysical priority, there can be no essentially dispositional metaphysically fundamental properties, and the prospects of a “coherentist” metaphysics of basic properties are dim. A modal retreat that refrains from a post-modal conception of essence and simply claims that fundamental properties play dispositional roles by metaphysical necessity is unsatisfactory. (shrink)

In general, a given object could have been different in certain respects. For example, the Great Pyramid could have been somewhat shorter or taller; the Mona Lisa could have had a somewhat different pattern of colours; an ordinary table could have been made of a somewhat different quantity of wood. But there seem to be limits. It would be odd to suppose that the Great Pyramid could have been thimble-sized; that the Mona Lisa could have had the pattern of colours (...) that actually characterizes The Scream; or that the table could have been made of the very quantity of wood that in fact made some other table. However, there are puzzling arguments that purport to show that so long as an object is capable of being somewhat different in some respect, it is capable of being radically different in that respect. These arguments rely on two tempting thoughts: first, that an object’s capacity for moderate variation is a non-contingent matter, and second, that what is possibly possible is simply possible. This book systematically investigates competing strategies for resolving these puzzles, and defends one of them. Along the way it engages with foundational questions about the metaphysics of modality. (shrink)
Some things, but only some things, are by nature subject to standards. Why? I explain and develop what I call nature-first constitutivism, which says that what something is determines what it should be. Nature is the basis of normativity. I explain this view in terms of a unique type of property which particulars of a genus can lack even though those properties partially determines the nature of the genus. Such properties partially describe the nature of a genus and are thereby (...) normative for the particulars of that genus. Particulars of genera with such essential properties are by nature subject to standards with respect to those properties. Particulars of genera without such properties are not by nature subject to standards. (shrink)
Talk of powers is muddled. Building upon Powers and capacities in philosophy: The new aristotelianism, Routledge, London, 2012a, pp 207–227), I disambiguate four senses of the term: powers construed as activity, as capacity/potentiality, as essence and as necessity, respectively, in an attempt to clarify what it is that realists about causal powers take themselves to be realists about.
This paper argues, first, that the information problem poses a foundational challenge to mainstream semantics. It proposes, second, to address this problem by drawing on notions from Kit Fine’s essentialist framework. More specifically, it claims that the information problem can be avoided by strengthening standard truth theories, employing an operator expressing the notion of a relative constitutive semantic requirement. As a result, the paper proposes to construe semantic theories as theories of semantic requirements, and semantic knowledge as knowledge of such (...) requirements. (shrink)
This paper deals with generalisations of modally based criteria for determining whether a given property is essential to an individual to the case of generic essences. These criteria usually presuppose extensionally individuated properties. The limitations of their generalisations are demonstrated using the case of the necessarily empty individual property and the necessarily empty individual office. I do not present a novel stance on the discussion of individual essences. The novelty of this paper lies in its claim that none of these (...) criteria can be generalised to generic essences.

I defend a novel view of how social kinds (e.g., money, women, permanent residents) depend on our mental states. In particular, I argue that social kinds depend on our mental states in the following sense: it is essential to them that they exist (partially) because certain mental states exist. This analysis is meant to capture the very general way in which all social kinds depend on our mental states. However, my view is that particular social kinds also depend on our (...) mental states in more specific ways—some of them causal, others metaphysical. I defend a minimal but metaphysically important notion of essence—one that takes as primary that the essential properties of a kind constitute its identity—and argue that this minimal notion of essence is all that is needed to vindicate my claim that social kinds are essentially mind-dependent.

The debate about the nature of the representational format of concepts seems to have reached an impasse. The debate faces two fundamental problems. Firstly, amodalists (i.e., those who argue that concepts are represented by amodal symbols) and modalists (i.e., those who see concepts as involving crucially representations including sensorimotor information) claim that the same empirical evidence is compatible with their views. Secondly, there is no shared understanding of what a modal or amodal format amounts to. Both camps recognize that the (...) two formats play essential roles in higher cognition, leading to an increasing number of hybrid proposals. In this paper, I argue that the existence of those fundamental problems should make us suspicious about a modal/amodal dichotomy. Also, I suggest that hybrid approaches, as they currently stand, do not provide suitable solutions to the impasse. Instead, we should overcome the dichotomy and treat the modal/amodal distinction as a graded phenomenon. I illustrate this hypothesis with an example of a cognitive-computational model of concepts based on the Predictive Processing framework. (shrink)
Predicate nominals (e.g., “is a female”) seem to label or categorize their subjects, while their adjectival correlates (e.g., “is female”) merely attribute a property. Predicate nominals also elicit essentializing inferential judgments about inductive potential and stable explanatory membership. Data from psychology and semantics support that this distinction is robust and productive. I argue that while the difference between predicate nominals and predicate adjectives is elided by standard semantic theories, it ought not be. I then develop and defend a psychologically motivated (...) semantic account on which predicate nominals attribute kind membership and trigger a presupposition that underpins our essentialist judgments.

Paradoxes of nested modality, like Chisholm’s paradox, rely on S4 or something stronger as the propositional logic of metaphysical modality. Sarah-Jane Leslie’s objection to the resolution of Chisholm’s paradox by means of rejection of S4 modal logic is investigated. A modal notion of essence congenial to Leslie’s objection is clarified. An argument is presented in support of Leslie’s crucial but unsupported assertion that, on pain of inconsistency, an object’s essence is the same in every possible world. A fallacy in the (...) argument is exposed. Alternative interpretations of Leslie’s objection are provided and are found to involve equivocation between different notions of “essence.” A material artifact’s modal essence, as distinct from its quiddity essence, could have been different than it is.

This paper is about the so-called meta-grounding question, i.e. the question of what grounds grounding facts of the sort ‘φ is grounded in Γ ’. An answer to this question is pressing since some plausible assumptions about grounding and fundamentality entail that grounding facts must be grounded. There are three different accounts on the market which each answer the meta-grounding question differently: Bennett’s and deRosset’s “Straight Forward Account” (SFA), Litland’s “Zero-Grounding Account” (ZGA), and “Grounding Essentialism” (GE). I argue that if (...) grounding is to be regarded as metaphysical explanation (i.e. if unionism is true), (GE) is to be preferred over (ZGA) and (SFA) as only (GE) is compatible with a crucial consequence of the thought that grounding is metaphysical explanation. In this manner the paper contributes not only to discussions about the ground of ground but also to the ongoing debate concerning the relationship between ground, essence, and explanation. (shrink)
In defense of anti-essentialism, pragmatist Richard Rorty holds that we may think of all objects as if they were numbers. I find that Rorty’s metaphysics hinges on two rather weak arguments against the essences of numbers. In contrast, Plato’s metaphysics offers a plausible definition of essentiality by which numbers do have essential properties. Further, I argue that Rorty’s argumentative mistake is mischaracterizing Plato’s definition. I conclude that Plato’s definition of “essential” is a robust one which implies that many properties, beyond (...) those we might intuitively think of, can count as essential properties of objects.

Discussions about dispositional and categorical properties have become commonplace in metaphysics. Unfortunately, dispositionality and categoricity are disputed notions: usual characterizations are piecemeal and not widely applicable, thus threatening to make agreements and disagreements on the matter merely verbal—and also making it arduous to map a logical space of positions about dispositional and categorical properties in which all parties can comfortably fit. This paper offers a prescription for this important difficulty, or at least an inkling thereof. This will be achieved by (...) comparing pairs of positions and exploring their background metaphysics to discover where alleged agreements and disagreements concerning dispositionality and categoricity really lie; more specifically, the Pure Powers view and the Powerful Qualities view will be under scrutiny. Over this background, the prescription functions by isolating a successful identity-based characterization of categoricity, while abandoning the correspondent identity-based characterization of dispositionality. On the contrary, according to this prescription a property is dispositional if and only if it is solely in virtue of possessing that property that its bearer is assigned a certain dispositional profile. A crucial consequence of this prescription is that, while supporters of the Pure Powers view often characterize their position as an essentialist one, the dispositionality of properties needn’t always be a matter of essence.

The theory of essential definitions is a fundamental anti‐sceptic element of the Aristotelian‐Avicennian epistemology. In this theory, when we distinguish the genus and the specific differentia of a given essence we thereby acquire a scientific understanding of it. The aim of this article is to analyse systematically the sceptical reasons, arguments and conclusions against real definitions of three major authorities of twelfth‐century Arabic philosophy: Faḫr al‐Dīn al‐Rāzī, Šihāb al‐Dīn al‐Suhrawardī and Abū l‐Barakāt al‐Baġdādī. I focus on showing how their refutation (...) of our capacity to provide essential definitions of things is rooted in their semantic theory: we only know things under certain descriptions which are identical to the meanings of the words that we use to refer to them, yet these descriptions do not capture the essences of things in themselves. The best result one can achieve with Aristotelian‐Avicennian scientific definitions is a “nominal definition”. With this, Rāzī, Suhrawardī and Abū l‐Barakāt will put some serious epistemic limitations on our capacity to attain scientific knowledge of things, at least as Aristotle and Avicenna would have it.

In this paper I argue against Mark Jago’s recent suggestion that ordinary knowers can move from knowledge of essence to knowledge of metaphysical necessity.
According to McGinn, the aim of philosophy is to discover essences through conceptual analysis, and it qualifies as a game in Suits’ sense. However, everything in Suits’ definition of game seems to exclude from its scope McGinn’s definition of philosophy. Here I criticise McGinn’s definition and offer a more comprehensive one. Incidentally, this definition will allow us to include philosophy within the class of activities that do satisfy Suits’ definition of game.
This paper evaluates six contenders which might be invoked by essentialists in order to meet Quine’s challenge, viz., to provide necessary and sufficient conditions for the crossworld identity of individuals: (i) an object’s qualitative character; (ii) matter; (iii) origins; (iv) haecceities or primitive non-qualitative thisness properties; (v) “world-indexed properties”; and (iv) individual forms. The first three candidates, I argue, fail to provide conditions that are both necessary and sufficient for the crossworld identity of individuals; the fourth and fifth criteria are (...) open to the charge that they do not succeed in meeting Quine’s demand in an explanatorily adequate fashion. On balance, then, individual forms, or so I propose, deserve to be taken very seriously as a possible response to Quine’s challenge, especially by neo-Aristotelians who are already committed to a hylomorphic conception of composite concrete particular objects for other reasons. Theorists who also accept a non-modal conception of essence, i.e., a conception according to which essence is not reducible to modality, in addition face the further difficult task, over and above what is required to meet Quine’s challenge, of having to explain how an object’s de re modal profile in some way follows from facts about its essence. Haecceities and world-indexed properties, as I indicate, are unlikely to be of much help with respect to this second challenge, while the forms of hylomorphic compounds are in fact well-suited for this purpose.

This article responds to a case-based argument by Mark Richard that rule of reference is not essential to meaning. It objects that the argument requires shifting between understanding the relevant term in the case, ‘marriage,’ as a determinable, in order to support one premise, and a determinate, in order to support another. On no univocal interpretation can both premises be made true.
Most linguists and philosophers will tell you that whatever meaning is, it determines the reference of names, the satisfaction conditions of nouns and verbs, the truth conditions of sentences; in linguist speak, meaning determines semantic value. So a change in semantic value implies a change in meaning. So the semantic value a meaning determines is essential to that meaning: holding contributions from context constant, if two words have different semantic values they cannot mean the same thing. If this is correct, (...) then in a fairly straightforward sense reference is essential to meaning. In this paper I argue that reference is not essential to meaning by giving an example in which groups in different circumstances use a phrase with the same meaning but a different reference. (shrink)
A generic grounding claim is a grounding claim that isn’t about any particular entity or fact. For example, consider the claim: an act is right in virtue of maximizing happiness. One natural idea is that generic grounding claims state mere regularities of ground. So if an act is right in virtue of maximizing happiness, then every possible right act is right in virtue of maximizing happiness. The generic claim generalizes over particular grounding relations. In this essay, I argue that this (...) simple story is wrong. Generic grounding claims are not merely quantificational; rather, they express real definitions, where real definitions are (in part) claims about essence. My view has two major upshots: ('i') it makes better sense of debates where generic grounding claims are at issue (like debates about moral laws); ('ii') it clarifies the distinction between reductive and non-reductive metaphysical theories.

A standard conception of metaphysical modality accepts that Some de re modal claims are true, These should be understood in terms of a possible worlds semantics, and There is trans-world identity. For instance, it seems true that Humphrey could have won the election. In possible worlds speak, we say that there exists a possible world where Humphrey wins the election. Furthermore, had that possibility been actualized instead of this one, Humphrey—our Humphrey, the very same man—would still have existed. Here, I (...) argue that this way of understanding de re modal claims, in conjunction with certain other plausible assumptions, entails that The World is a necessary being. (shrink)
The idea of fragmentalism has been proposed by Kit Fine as a non-standard view of tense realism. This paper examines a modal version of the view, called modal fragmentalism, which combines genuine realism and realism of modality. Modal fragmentalism has been recently discussed by Iaquinto. But unlike Iaquinto, who primarily focused on possibilities de re, in this paper, we focus on expressions of possibilities de dicto. We argue that the chief idea of modal realism should be that different worlds are (...) distinguished not just in terms of how things are differently with respect to each world, but also in terms of how things could have been differently with respect to each world. This demands a realism-oriented semantics for suppositional contents, and more specifically, for conditionals. By deploying a multidimensional semantics for conditionals, we show that there are good reasons to consider modal fragmentalism as a serious approach in metaphysics, which shares many similarities with the fragmentalism of tense.

Kit Fine has proposed a new solution to what he calls ‘a familiar puzzle’ concerning modality and existence. The puzzle concerns the argument from the alleged truths ‘It is necessary that Socrates is a man’ and ‘It is possible that Socrates does not exist’ to the apparent falsehood ‘It is possible that Socrates is a man and does not exist’. We discuss in detail Fine’s setting up of the ‘puzzle’ and his rejection, with which we concur, of two mooted solutions (...) to it. (One of these uses standard, Kripkean, notions, and the other rests on work done by Arthur Prior.) We set out, and reject, the philosophy of modality underlying Fine’s new solution, and we defend an alternative response to the alleged puzzle. Our solution follows the work of David Wiggins in distinguishing between the sentential operator ‘It is necessary that’ and the predicate modifier ‘necessarily’. We briefly provide this distinction with a possible- world semantics on which it is neither a necessary truth, in some sense, that Socrates exists nor true, in some sense, that Socrates necessarily exists.

The argument from absence of analysis (AAA) infers primitivism about some x from the absence of a reductive analysis ofx. But philosophers use the word ‘primitive’ to mean many distinct things. I argue that there is a robust sense of ‘primitive’ present in the metaphysics literature that cannot be inferred via the AAA. Successfully demonstrating robust primitivism about somexrequires showing two things at once: that a reduction ofxis not possible and that an explanatorily deep characterization ofxis not available. In order (...) to secure this second explanatory claim, the AAA must wrongly assume that reductive analysis is our only source of explanatory characterization. I argue that this is false by offering a distinct way of providing explanatory characterizations backed by suitably understood metaphysical constraints. While there remains a minimal sense of ‘primitive’ inferable via the AAA, this sense is exhausted by the denial of reduction. With minimal primitivism as its target, the AAA is uninteresting. (shrink)
