Haecceitism

We live in a contingent world, a world that could have been different. A common way to deal with this contingency is by positing the existence of all possibilities. This, however, doesn’t get rid of the contingency – it merely moves it from the third-person view to the first-person view.

This essay aims to redress the contention that epistemic possibility cannot be a guide to the principles of modal metaphysics. I argue that the interaction between the two-dimensional intensional framework and the mereological parthood relation enables epistemic possibilities to target the haecceitistic properties of individuals. I specify, then, a two-dimensional intensional formula encoding the relation between the epistemic possibility of haecceity comprehension and its metaphysical possibility. I examine the Julius Caesar problem as a test case. I then generalize the approach (...) to essential properties. I conclude by addressing objections from the indeterminacy of ontological principles relative to the space of epistemic possibilities, and from the consistency of epistemic modal space. (shrink)

Is everything about reality either qualitative or somehow determined by the qualitative character of reality itself? Metaphysical anti-Haecceitism is often taken to be the claim that this is the case, and to entail that reality is fundamentally qualitative. In this paper, I argue against the idea that metaphysical anti-Haecceitism should be characterized in such terms, and defend a novel way to phrase such a view. This will be done by taking the main arguments for anti-Haecceitism as a guide and by (...) singling out the proper commitments of a view that satisfies the desideratum set forth by such arguments. The phrasing I shall offer will help tell the issue of anti-Haecceitism apart from some concerns about fundamentality that, I will contend, are orthogonal to it—among them, the question whether there is fundamentality at all.

Jean-Luc Nancy takes the concept of "essence" in order to indicate its drawbacks on the singularity of being. The concept of essence is not a universal and necessary origin, but contingent and historical meanings for Nancy. This historicity in meaning leads Nancy to question the concept of the individual and the rules of the social/public sphere allocated through individuality. Nancy's argument on the ontological environment of finite beings aims to highlight those beings are mixed singular, not belonging to a universal (...) unit. This allows us to discover that being is singular and also singular-plural to the extent that it is with the other. Thus, essential historical concepts invalidate individual or social organizations at this point. Nancy calls this “finitude” which is the only transcendental concept that makes possible the “being with” (Mitsein). It is possible to think that finitude is the only property to make a community of singularities rather than ready-made concepts of social sciences. I argue that this position is methodological for an alternative socio-ontology. (shrink)

Lynne Baker’s case for the incompatibility of naturalism with the first-person perspective raises a range of questions about the relationship between naturalism and the various properties involved in first-person perspectives. After arguing that non-qualitative properties—most notably, haecceities like being Lynne Baker—are ineliminably tied to first-person perspectives, this paper considers whether naturalism and non-qualitative properties are, in fact, compatible. In doing so, the discussion focus on Shamik Dasupgta’s argument against individuals and, in turn, non-qualitative properties. Several strategies for undermining Dasgupta's argument (...) are considered, drawing on de re laws and haecceitistic possibilities. Finally, an analogy is drawn between naturalism and platonism regarding mathematical entities and naturalism's parallel commitment to individuals. I conclude that naturalists are obliged to posit non-qualitative properties. (shrink)

The consensus among spacetime substantivalists is to respond to Leibniz's classic shift arguments, and their contemporary incarnation in the form of the hole argument, by pruning the allegedly problematic metaphysical possibilities that generate these arguments. Some substantivalists do so by directly appealing to a modal doctrine akin to anti-haecceitism. Other substantivalists do so by appealing to an underlying hyperintensional doctrine that implies some such modal doctrine. My first aim in this paper is to pose a challenge for all extant forms (...) of this consensus position. My second aim is to show what form substantivalism must take in order to uphold the consensus while addressing this challenge. The result is a novel "plenitudinous" substantivalist view, which predicts that certain modal facts about spacetime are vague or indeterminate. I then argue against this view on independent grounds, concluding that substantivalists should reject the consensus position. The paper also discusses the way forward for substantivalists in light of this conclusion. (shrink)

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.

According to strong pluralism, objects distinct by virtue of their modal properties can coincide. The most common objection towards such view invokes the so-called Grounding Problem according to which the strong pluralist needs to explain what the grounds are for supposed modal differences between the coincidents. As recognized in the literature, the failure to provide an answer to the Grounding Problem critically undermines the plausibility of strong pluralism. Moreover, there are strong reasons to believe that strong pluralists cannot provide an (...) explanation of the Grounding Problem. In this paper, we argue that strong pluralism can be motivated independently of the successful answer to the Grounding Problem. In order to achieve that aim, we provide a haecceitistic interpretation of strong pluralism according to which strong pluralism should be read as a position committed to the existence of primitive individuals, i.e., the individuals that have their criteria of individuation independently of their qualitative profiles. That said, we do not aim at defending haecceitism. Instead, our aim is rather modest: we want to provide a new way for the strong pluralist to supplement his view to make it more watertight.

Some properties such as having a beard and being a philosopher are intuitively qualitative, while other properties such as being identical to Plato and being a student of Socrates are intuitively non-qualitative. It is often assumed that, necessarily, a property is qualitative if and only if it can be designated descriptively without the aid of directly referential devices. I argue that this linguistic thesis fails in both directions: there might be non-qualitative properties that can be designated descriptively, and there appear (...) to be qualitative properties that can only be designated directly. I conclude that while the linguistic thesis is ultimately untenable as stated, it can be plausibly recast as a thesis about our concepts rather than the properties they designate. (shrink)

Cases of grounding failure present a puzzle for fundamental metaphysics. Typically, solutions are thought to lie either in adding ontology such as haecceities or in re‐describing the cases by means of the ideology of metaphysical indeterminacy. The controversial status of haecceities has led some to favour metaphysical indeterminacy as the way to solve the puzzle. We consider two further treatments of grounding failure each of which, we argue, is a more plausible alternative. As such, the initial dichotomy is a false (...) one, and these alternative options deserve consideration before resorting to the heavyweight machinery of metaphysical indeterminacy. -/- . (shrink)

In Form, Matter, Substance, Kathrin Koslicki articulates and defends her preferred brand of hylomorphism, weighing in on how we should conceive of the matter and the form of such compounds, and on how they can qualify as fundamental “substances” despite being ontologically dependent on their components. I review Koslicki’s principal claims and conclusions (§1), and then raise some concerns about her master argument for “individual forms” (§2) and her criticism of standard essentialist accounts of artifacts (§3).

A standard contemporary formulation of essentialism defines essential properties with a help of a concept of possible worlds. It is often argued that in order to use possible worlds effectively, facts about transworld identity of individuals need to be determined. In this paper I discuss how essentialist might attempt the issue of transworld identity of individuals. Specifically, I analyze a connection between essentialism and the two theories that explain the transworld identity issue, that is, haecceitism and antihaecceitism. I provide a (...) detailed analysis of different variants of antihaecceitism and argue, that all of them are incompatible with basic intuitions that stay behind essentialism. In contrast to that, I defend a position that essentialism ought to be combined with some form of haecceitism. In the remainder of this paper I provide the two ways through which essentialist might be a haecceitist. (shrink)

Jason Bowers and Meg Wallace have recently argued that those who hold that every individual instantiates a ‘haecceity’ are caught up in a Euthyphro-style dilemma when confronted with familiar cases of fission and fusion. Key to Bowers and Wallace’s dilemma are certain assumptions about the nature of metaphysical explanation and the explanatory commitments of belief in haecceities. However, I argue that the dilemma only arises due to a failure to distinguish between providing a metaphysical explanation of why a fact holds (...) vs. a metaphysical explanation of what it is for a fact to hold. In the process, I also shed light on the explanatory commitments of belief in haecceities. (shrink)

Background independence begins life as an informal property that a physical theory might have, often glossed as 'doesn't posit a fixed spacetime background'. Interest in trying to offer a precise account of background independence has been sparked by the pronouncements of several theorists working on quantum gravity that background independence embodies in some sense an essential discovery of the General Theory of Relativity, and a feature we should strive to carry forward to future physical theories. This paper has two goals. (...) The first is to investigate what a world must be like in order to be truly described by a background independent theory given extant accounts of background independence. The second is to argue that there are no non-empirical reasons to be more confident in theories that satisfy extant accounts of background independence than in theories that don't. The paper concludes by drawing a general moral about a way in which focussing primarily on mathematical formulations of our physical theories can adversely affect debates in the metaphysics of physics.

The hole argument purports to show that all spacetime theories of a certain form are indeterministic, including the General Theory of Relativity. The argument has given rise to an industry of searching for a metaphysics of spacetime that delivers the right modal implications to rescue determinism. In this paper, I first argue that certain prominent extant replies to the hole argument—namely, those that appeal to an essentialist doctrine about spacetime—fail to deliver the requisite modal implications. As part of my argument, (...) I show that threats to determinism of the sort brought out by the hole argument are more general than has heretofore been recognized. I then use these results to propose a novel essentialist doctrine about spacetime that successfully rescues determinism, what I call sufficiency metric essentialism. However, I go on to argue that once we realize what an essentialist doctrine about spacetime must look like in order to address the hole argument, we should reject all such doctrines, because they can't fulfill their ambition of improving on standard modal replies to the argument. I close by suggesting some lessons for future work on spacetime and the metaphysics of physics more broadly, and also drawing some general morals for contemporary metaphysics, in particular about (i) whether essence can be used to articulate a precise structuralist doctrine, and (ii) the relationship between essence and modality.

Haecceitism is the thesis that, necessarily, in addition to its qualities, each thing has a haecceity or individual essence. The purpose of this paper is to expose a flaw in haecceitism: it entails that familiar cases of fission and fusion either admit of no explanation or else only admit of explanations too bizarre to warrant serious consideration. Because the explanatory problem we raise for haecceitism closely resembles the Euthyphro problem for divine command theory, we refer to our objection as the (...) haecceitic Euthyphro problem, or the Haecceitic Euthyphro for short. We conclude that the objection is decisive against haecceitism. (shrink)

I examine three ‘anti-object’ metaphysical views: nihilism, generalism, and anti-quantificationalism. After setting aside nihilism, I argue that generalists should be anti-quantificationalists. Along the way, I attempt to articulate what a ‘metaphysically perspicuous’ language might even be.

According to haecceitism, some maximal possibilities differ even while they are qualitatively indiscernible. Since haecceitism is a modal thesis, it is typically defended by appeal to conceivability arguments. These arguments require us to conceive of qualitatively indiscernible possibilities that differ only with respect to the identity of the individuals involved. This paper examines a series of conceivability arguments for haecceitism and a variety of anti-haecceitist responses. It concludes that there is no irresistible conceivability argument for haecceitism even while anti-haecceitist responses (...) do come with certain notable commitments. (shrink)

Suppose that all non-qualitative facts are grounded in qualitative facts. I argue that this view naturally comes with a picture in which trans-world identity is indeterminate. But this in turn leads to either pervasive indeterminacy in the non-qualitative, or else contingency in what facts about modality and possible worlds are determinate.

The distinction between qualitative properties like mass and shape and non-qualitative properties like being Napoleon and being next to Obama is important, but remains largely unexamined. After discussing its theoretical significance and cataloguing various kinds of non-qualitative properties, I survey several views about the nature of this distinction and argue that all proposed reductive analyses of this distinction are unsatisfactory. I then defend primitivism, according to which the distinction resists reductive analysis.

It is argued that from a genuine Leibnizian point of view the well-known thought experiment, call it BTE, involving a possible world with only two exactly similar objects, cannot be used to refute Leibniz's Principle of the Identity of Indiscernibles (LIdI). If the claim that there are two objects in BTE is based on primitive thisnesses, the Leibnizian objection is that there are no such things; and even if there were, then, quite generally, something true of one object – that (...) it has its primitive thisness – would not be true of the other. Secondly, if the duality claim is based on a primitive, irreducible relation of distinctness, the Leibnizian objection is that there are no irreducible relations. Finally, if it is said that the (putatively) two objects in BTE cannot be separately individuated, then BTE is not a counter-example to LIdI, because if there is no individuation, there are no individuals either, while LIdI presupposes that there are individuals.

David Lewis holds that a single possible world can provide more than one way things could be. But what are possible worlds good for if they come apart from ways things could be? We can make sense of this if we go in for a metaphysical understanding of what the world is. The world does not include everything that is the case—only the genuine facts. Understood this way, Lewis's “cheap haecceitism” amounts to a kind of metaphysical anti-haecceitism: it says there (...) aren't any genuine facts about individuals over and above their qualitative roles. (shrink)

It is a commonsense thesis that unactualized possibilities are not parts of actuality. To keep his modal realism in line with this thesis, David Lewis employed his indexical account of the term “actual.” I argue that the addition of counterpart theory to Lewis’s modal realism undermines his strategy for respecting the commonsense thesis. The case made here also reveals a problem for Lewis’s attempt to avoid haecceitism.

Existentialism concerning singular propositions is the thesis that singular propositions ontologically depend on the individuals they are directly about in such a way that necessarily, those propositions exist only if the individuals they are directly about exist. Haecceitism is the thesis that what non-qualitative facts there are fails to supervene on what purely qualitative facts there are. I argue that existentialism concerning singular propositions entails the denial of haecceitism and that this entailment has interesting implications for debates concerning the philosophy (...) of language, the nature of propositions, and the metaphysics of modality.

En este artículo discuto cómo es que la idea intuitiva de que las cosas podrían cambiar, combinada con principios excesivamente plausibles, nos lleva a la paradoja de Chisholm. Arguyo que la mejor respuesta a esta paradoja –pues efectúa la menor mutilación a nuestros principios teóricos y asunciones intuitivas– es la postura esencialista. Primero expongo algunas motivaciones para hacer una teoría metafísica que explique la modalidad de re. Luego reviso los principios a los que estaremos regresando en el curso del artículo. (...) Entonces muestro cómo ellos, conjuntamente, implican la paradoja de Chisholm. Después reviso las posibles fuentes de esta paradoja, rechazando varias salidas posibles. Argumento que la fuente de la paradoja está en que nuestros principios teóricos son demasiado liberales, y que la opción esencialista subsana este defecto. (shrink)

Some philosophers respond to Leibniz’s “shift” argument against absolute space by appealing to antihaecceitism about possible worlds, using David Lewis’s counterpart theory. But separated from Lewis’s distinctive system, it is difficult to understand what this doctrine amounts to or how it bears on the Leibnizian argument. In fact, the best way of making sense of the relevant kind of antihaecceitism concedes the main point of the Leibnizian argument, pressing us to consider alternative spatiotemporal metaphysics.

In “Ducking Friendly Fire: Davison on the Grounding Objection”, William Lane Craig responds to a statement of The Grounding Objection articulated by Scott Davison in “Craig on the Grounding Objection to Middle Knowledge”. According to Davison, unless we have an explanation of true counterfactuals that makes reference to actual human persons in specific situations we lack an adequate explanation of how counterfactuals of creaturely freedom could possibly be true. Drawing from and elaborating on Edward Wierenga’s response to The Grounding Objection (...) in “Providence, Middle Knowledge, and the Grounding Objection”, I formulate and motivate a view that satisfies the plausible requirement that the grounds for God’s knowledge of true counterfactuals of creaturely freedom are actually existent things while eschewing Davison’s implausibly strong requirement that the things in question must be specific human persons in specific situations. I conclude that, contrary to Davison, facts about uninstantiated human person essences can do at least some of the relevant explanatory work. (shrink)

Two arguments are offered here for postulating individual essences of concrete individuals on top of their sortal essences. One is the explanatory gap argument, the other draws on the analogy with the individual essences of events presupposed in single causal explanations. These arguments support qualitative individual essences with explanatory goals as opposed to hybrid impure relational essences accounting for origin and numerical identity. It is highlighted why origin properties as parts of impure relational essences do not yield genuine de re (...) constructions. The distinction between the two types of individual essences is traced back to the ambiguity of the very notion of individuation. (shrink)

In this paper, I examine the putative incompatibility of three theses: (1) Haecceitism, according to which some maximal possibilities differ solely in terms of the non-qualitative or de re possibilities they include; (2) Modal correspondence, according to which each maximal possibility is identical with a unique possible world; (3) Counterpart theory, according to which de re modality is analyzed in terms of counterpart relations between individuals. After showing how the modal realism defended by David Lewis resolves this incompatibility by rejecting (...) modal correspondence, I defend modal correspondence and develop an alternative strategy for reconciling these theses. Specifically, I examine Lewis’s arguments against non-qualitative counterpart theory and undermine them by developing a novel version of non-qualitative counterpart theory that appeals to a metaphysics of bare particulars. I then indicate how this version of non-qualitative counterpart theory accommodates both haecceitism and modal correspondence. (shrink)

Antihaecceitists believe that all facts about specific individuals—such as the fact that Fred exists, or that Katie is tall—globally supervene on purely qualitative facts. Haecceitists deny that. The issue is not only of interest in itself, but receives additional importance from its intimate connection to the question of whether all fundamental facts are qualitative or whether they include facts about which specific individuals there are and how qualitative properties and relations are distributed over them. Those who think that all fundamental (...) facts are qualitative are arguably committed to antihaecceitism. The goal of this paper is to point out some problems for antihaecceitism (and therefore for the thesis that all fundamental facts are qualitative). The article focuses on two common assumptions about possible worlds: (i) Sets of possible worlds are the bearers of objective physical chance. (ii) Counterfactual conditionals can be defined by appeal to a relation of closeness between possible worlds. The essay tries to show that absurd consequences ensue if either of these assumptions is combined with antihaecceitism. Then it considers a natural response by the antihaecceitist, which is to deny that worlds play the role described in (i) and (ii). Instead, the reply continues, we can introduce a new set of entities that are defined in terms of worlds and that behave the way worlds do on the haecceitist position. That allows the antihaecceitist to formulate antihaecceitist friendly versions of (i) and (ii) by replacing the appeal to possible worlds with reference to the newly introduced entities. This maneuver invites an obvious reply, however. If the new entities are the things that play the role we typically associate with worlds, as partially described by (i) and (ii), then it is natural to conclude that they really are the entities we talk about when we speak of worlds, so that haecceitism is true after all. (shrink)

Anti-haecceitism is the thesis that things cannot differ from actuality in a purely non-qualitative fashion. Anti-haecceitism being a modal notion, we would expect it to be explicable in terms of possible worlds. Bradford Skow denied that, arguing that alternative conceptions of possible worlds prompt non-equivalent characterizations of anti-haecceitism. Therefore, the haecceitism debate should take place in the modal language, rather than in the language of possible worlds. The aim of this paper is to provide a metaphysically neutral possible-world characterization of (...) anti-haecceitism, i.e. one compatible with alternative understandings of the nature of possible worlds.

This paper is concerned with a popular view about the nature of propositions, commonly known as the Russellian view of propositions. Alvin Plantinga has dubbed it, or more precisely, a crucial consequence of it, Existentialism, and in his paper “On Existentialism” (1983) he has presented a forceful argument intended as a reductio of this view. In what follows, I describe the main relevant ingredients of the Russellian view of propositions and states of affairs. I present a relatively simple response Russellians (...) might want to make to Plantinga’s anti-existentialist argument. I then explore one aspect of this response—one that leads to some rather curious consequences for the Russellian view of propositions and states of affairs. (shrink)

If a counterpart theorist’s understanding of the counterpart relation precludes haecceitist differences between possible worlds, as David Lewis’s does, how can he admit haecceitist possibilities, as Lewis wants to? Lewis (Philosophical Review 3–32, 1983; On the Plurality of Worlds, 1986) devised what he called a ‘cheap substitute for haecceitism,’ which would allow for haecceitist possibilities while preserving the counterpart relation as a purely qualitative one. The solution involved lifting an earlier (Journal of Philosophy 65(5):113–126, 1968; 68(7):203–211, 1971) ban on there (...) being multiple intra-world counterparts. I argue here that serious problems for ‘cheap haecceitism’ lurk very close to its surface, and they emerge when we consider the effect of using an actuality operator in our language. Among the most serious of the problems is the result that being the case in some possible world does not always suffice for possibly being the case. The result applies to any counterpart theory that employs a purely qualitative counterpart relation. The upshot is that if we are to admit haecceitist possibilities, as we should, then we must reject any purely qualitative relation as the one involved in the analysis of what might have been for an individual.

States of affairs raise, among others, the following questions: What kind of entity are they (if there are any)? Are they contingent, causally efficacious, spatio-temporal and perceivable entities, or are they abstract objects? What are their constituents and their identity conditions? What are the functions that states of affairs are able to fulfil in a viable theory, and which problems and prima facie counterintuitive consequences arise out of an ontological commitment to them? Are there merely possible (non-actual, non-obtaining) states of (...) affairs? Are there molecular (i.e., negative, conjunctive, disjunctive etc.) states of affairs? Are there modal and tensed states of affairs? In this volume, these and other questions are addressed by David M. Armstrong, Marian David, Herbert Hochberg, Uwe Meixner, L. Nathan Oaklander, Peter Simons, Erwin Tegtmeier and Mark Textor. (shrink)

Nathan Salmon, in his paper Trans-World Identification and Stipulation (1996) purports to give a proof for the claim that facts concerning trans-world identity cannot be conceptually reduced to general facts. He calls this claim ‘Extreme Haecceitism.’ I argue that his proof is fallacious. However, I also contend that the analysis and ultimate rejection of his proof clarifies the fundamental issues that are at stake in the debate between the reductionist and haecceitist solutions to the problem of trans-world identity. These issues (...) hinge on the ability of modal logic and possible worlds semantics to draw a hard and fast distinction between the logic and the metaphysics of modal logic. I shall claim that the considerations in this paper call into question the viability of such a distinction. (shrink)

An introduction to cat metaphysics..........

Possible-worlds talk obscures, rather than clarifies, the debate about haecceitism. In this paper I distinguish haecceitism and anti-haecceitism from other doctrines that sometimes go under those names. Then I defend the claim that there are no non-tendentious definitions of ‘haecceitism’ and ‘anti-haecceitism’ using possible-worlds talk. That is, any definition of ‘haecceitism’ using possible-worlds talk depends, for its correctness, on a substantive theory of the nature of possible worlds. This explains why using possible-worlds talk when discussing haecceitism causes confusion: if the (...) parties to the discussion presuppose different theories of the nature of possible worlds, then they will mean different things by ‘haecceitism’.

In “Can the New Tenseless Theory of Time be Saved by Individual Essences?” Smith objects to the co-reporting theory on the groundsthat, since it grants that every time “now” is tokened it expresses a unique individual essence of that time which can be apprehended only at that time, the co-reporting theory is consistent with an A-theory of time that holds that each moment of time acquires its own particular property of presentness. I argue that Smith’s conclusion does not follow, since (...) moments of time have world-indexed properties which, though distinct from the individual essences ascribed to them by the use of “now,” are expressible by the use ofdate-expressions.

Der Topos von der Unerschöpflichkeit des Gegenstands wird mit der Phänomenologie assoziiert. Den ihm verwandten Topos von der Unaussprechlichkeit des Individuellen haben Goethe und die deutschen Romantiker in die Welt getragen. Der Diktion der analytischen Philosophie sind die Ausdrücke „unerschöpflich“ und „unaussprechlich“ fremd. Dieser Umstand sollte analytische Philosophen nicht davon abhalten, sich den sprachphilosophischen und ontologischen Problemen zuzuwenden, die sich hinter den besagten Formeln verbergen. Husserls Wort für Unerschöpflichkeit ist „Fülle“. Die „Fülle des Gegenstandes“ erläutert Husserl als den „Inbegriff der (...) ihn konstituierenden Bestimmtheiten“, seine „individualisierenden Bestimmtheiten“ eingeschlossen. Ich werde in diesem Aufsatz von deskriptiver Unerschöpflichkeit sprechen, die ich auf eine ontische Eigenart der konkreten Einzeldinge zurückführe. Den Begriff der deskriptiven Unerschöpflichkeit werde ich zunächst anhand des Problems entwickeln, die Eigenschaften eines Einzeldings zu zählen. Aristoteles, Leibniz und Kant beantworten die Frage, wie viele Eigenschaften ein Einzelding hat, gleichlautend: es sind potentiell unendlich viele (1.). Die ontologische Kategorie, für die dies gilt, ist die der konkreten, raumzeitlichen Einzeldinge (2.). Unter (3.) wird der Befund der deskriptiven Unerschöpflichkeit näher erläutert und ausdifferenziert. Unter (4.) wird ein sprachphilosophisch motivierter Einwand gegen die Unerschöpflichkeitsthese diskutiert und zurückgewiesen: der Einwand aus der endlichen Zahl der Prädikate. Dann werde ich die Begriffe Leerstelle, Auflösung und ontische Dichte einführen, um meinen Befund zu sichern und zu präzisieren (5.). Unter dem Stichwort „Unerschöpflich oder bloß faktisch unerschöpft?“ diskutiere ich die Frage, worin das prinzipielle Hindernis für das Unternehmen liegen soll, ein Einzelding erschöpfend zu beschreiben (6.). Anschließend kontrastiere ich die Unerschöpflichkeitsthese mit der pathetischen Formel von der „Unaussprechlichkeit des Individuellen“, um zu verdeutlichen, was mit ersterer nicht gemeint ist (7.). Diese Diskussion führt zu ontologischen Überlegungen über Individualität, Einzigkeit und haecceitas (8.). Schließlich bringe ich den Gedanken ins Spiel, daß wir in der natürlichen Sprache beliebig feine semantische Unterscheidungen treffen können, der auf den ersten Blick in einer gewissen Spannung zur These der deskriptiven Unerschöpflichkeit steht. Diese Spannung werde ich unter (9.) und (10.) zu mildern suchen und dabei meinen Begriff der ontischen Dichte zu Goodmans Begriff der semantischen Dichte in Beziehung setzen. (shrink)

A novel treatment of an issue central to much current work in metaphysics: the distinction between the essential and accidental properties of individuals. Mackie challenges widely held views, and arrives at what she calls "minimalist essentialism," an unorthodox theory according to which ordinary individuals have relatively few interesting essential properties. Mackie's clear and accessible discussions of issues surrounding necessity and essentialism mean that the book will appeal as much to graduate students as it will to seasoned metaphysicians.

Starting from an anecdote reported by Ernst Mach in the Analysis of Sensations, the author shows how the distinction between intentionality de re and intentionality de se can contribute to solving the individuation problem, at least for those individuals who are capable of self-referentiality. Intentionality is expressed linguistically in the form of the oratio obliqua, in the context of which the subordinate can be false even when the whole is true. The analysis of the conditions of falsity of the subordinate (...) tells us that this can be false either because the predicate does not fit to the subject or by a failure of reference, conceived according to the descriptive theory of reference. The intentionality de se is peculiar precisely by the fact that in this case the reference cannot fail and uniquely individuates the haecceitas of the intentional subject. (shrink)

Socrates, for example, has an essence that includes more than his human nature, which is his specific essence; he has an essence proper to himself alone, an essence that cannot be had by anyone else. Although Socrates does have singular (individualized) forms, his singular essence is not a form—there is no form Socrateity for the singular essence parallelling the form humanity for the specific essence. Instead, Socrates has his singular essence in consequence of being an individual, that is, in consequence (...) of having an ‘individual differentia’. Scotus further rejects the distinction between identity and individuality, maintaining that what it is for Socrates to be Socrates is the same as what it is for him to be an individual. Socrates, in the end, is his singular essence. (shrink)

A certain argument has been given in the literature to the effect that generalism (the view that all facts about all possible worlds can (in principle) be given in general terms, that is, without resorting to nonqualitative thisnesses) excludes transworld identitism (the view that there are numerical identities through possible worlds). It follows from this argument, among other things, that transworld identitism entails Scotistic haecceitism (acceptance of nonqualitative thisnesses), and that generalists subscribing to de reism (the view that there are (...) true modal statements de re) are committed to counterpartism (the view that sameness through worlds is not numerical identity). The purpose of this paper is to resist the argument in question by constructing generalist transworld identitism, that is, by providing an account involving identities through possible worlds, without resorting to nonqualitative thisnesses.
