Thisness Presentism outlines and defends a novel version of presentism, the view that only present entities exist and what is present really changes. Presentism is a view of time that captures a real and objective difference between what is past, present, and future, and which offers a model of reality that is dynamic and mutable, rather than static and immutable. The book advances a new defence of presentism by developing a novel ontology of thisness, combining insights about the (...) nature of essence, the metaphysics of propositions, and the relationship between true propositions and the elements of reality that make them true, alongside insights about time itself. It shows how, by accepting an ontology of thisness, presentists can respond to a number of pressing challenges to presentism, including claims that presentism cannot account for true propositions about the past, and that it is inconsistent with the reality of temporal passage and the openness of the future. This is one of the only book-length defences of presentism. It will be of interest to students and scholars working on the debate about presentism in the philosophy of time, as well as those interested in the metaphysics of propositions and truth-making, more generally.

Presentists, who believe that only present objects exist, should accept a thisness ontology, since it can do considerable work in defence of presentism. In this paper, I propose a version of presentism that involves thisnesses of past and present entities and I argue this view solves important problems facing standard versions of presentism.

According to the traditional view, visual objects can be characterized as bundles of features and locations. This initially plausible idea is contested within the contemporary psychology and philosophy of perception, where it is claimed that the visual system can represent objects as merely ‘this’ or ‘that’, in abstraction from their qualities. In this paper, I consider whether philosophical and psychological arguments connected with the rejection of the ‘bundle’ view of visual objects show that it is needed to postulate an additional, (...) purely individualizing characteristic, known in the philosophical tradition as ‘thisness’, within the structure of visual objects. I argue that the phenomenon of asymmetry of errors observed in Multiple Object Tracking experiments strongly suggests that reference to ‘thisness’ is needed if we are to formulate a proper diachronic identity criterion of visual objects.

The principle of the identity of indiscernibles holds that two individuals are the same individual if they have all the same properties. There are different forms of the principle, varying with what is allowed to count as a property. An individual has thisness if the weakest form of the principle does not apply to it. Abstract objects, places and times do not have thisness. Inanimate material objects probably do not. Animate beings, and the conscious events which involve them (...) do have thisness, and probably other events do as well. (shrink)

This essay is an investigation into the existence of a very unusual and some would say unacceptably exotic type of property: namely, the property of being a certain individual; or, if you prefer, the property of being identical to a certain individual. In other words, this essay will investigate whether in spite of their exotic nature there are thisnesses, and, in particular, whether thisnesses are instantiated by events. Of course, I have not really said enough yet about thisnesses to motivate (...) the criticism that such properties are exotic; for it might be the case that an individual x s thisness is merely a conjunction of all of x s qualitative properties. And, if we allow for the existence of all of the properties of an individual, it is not overly profligate to allow for the existence of this one additional conjunctive property. This, apparently, was Leibniz s view. Though seemingly ontologically mundane, however, such a qualitative1 thisness is not ontologically innocent. Given the definition of a thisness above, an individual s thisness is essential to it, and there are few philosophers who would wish to hold that all of an individual s properties are essential to it.2 Rather, it..

The project of grounding necessity in essence often goes together with the model of essence that assimilates the constitutive essence of an object to the definition of it. The paper argues that if the grounding project is to succeed, the definitional model must be questioned. Like any object whatever, a concrete individual is necessarily identical to that individual. It is argued that this necessity can have an essential ground only if the primitive identity property of it or its thisness (...) is essential to it, and the thisness is in its constitutive essence while not in the definition of it. A concrete individual is in essence partly definable but not fully explainable, for the definition of it forms a crucial part of its constitutive essence, but the constitutive essence includes something fundamental beyond definition or explanation. The definitional model must give way to a model of essence that accommodates this. (shrink)

This paper is about two puzzles, or two versions of a single puzzle, which deserve to be called paradoxes, and develops some apparatus in terms of which the apparently conflicting principles which generate the puzzles can be rendered consistent. However, the apparatus itself is somewhat controversial: the puzzles are modal ones, and the resolution to be advocated requires the adoption of a counterpart theoretic semantics of essentially the kind proposed by David Lewis, which in turn requires qualified rejection of certain (...) modal theses about identity which are valid in S5.

Presentists believe that only present things exist. But opponents insist this view has unacceptable implications: if only present things exist, we can’t express singular propositions about the past, since the obvious propositional constituents don’t exist, nor can we account for temporal passage, or the openness of the future. According to such opponents, and in spite of the apparent ‘common sense’ status of the view, presentism should be rejected on the basis of these unacceptable implications. In this paper, I present and (...) defend a version of presentism that avoids the unacceptable implications. The basic strategy I employ is familiar—I postulate presently existing entities to serve as surrogates for non-present entities—but some of the details of my proposal are more novel, and their application to these problems is certainly novel. One overarching thesis of this paper is that Thisness Presentism is preferable to other versions of presentism since it solves important problems facing standard iterations of the view. And I assume that this is a good positive reason in favour of the underlying thisness ontology. (shrink)

I have argued elsewhere that there are facts, and possibilities, that are not purely qualitative. In a second paper, however, I have argued that all possibilities are purely qualitative except insofar as they involve individuals that actually exist. In particular, I have argued that there are no thisnesses of nonactual individuals (where the thisness of x is the property of being x, or of being identical with x), and that there are no singular propositions about nonactual individuals (where a (...) singular proposition about an individual x is a proposition that involves or refers to x directly, perhaps by having x or the thisness of x as a constituent, and not merely by way of x's qualitative properties or relations to other individuals). I am also inclined to believe that there are not yet any thisnesses of individuals that will exist but do not yet, nor any singular propositions about future individuals--and, hence, that all possibilities are purely qualitative except insofar as they involve individuals that already do exist or have existed (counting timeless individuals, if any, as already existing). This thesis about the relation of time to thisness is the subject of the present paper, in which the conclusions of my previous papers will be presupposed. (shrink)

This paper seeks to give an account of what it is for an individual to instantiate thisness (i.e. primitive individual essence). Thisnesses are peculiar entities, and even those who endorse their existence and instantiation by objects/entities, have said very little about how an individual and its thisness are related. My approach will be to seek out a model for the instantiation of thisness by canvassing broadly Aristotelian accounts of the substance/attribute relation, and then by making appropriate modifications (...) to the most likely candidates in order to accommodate an individual's instantiation of thisness. What will emerge is that the model with the most utility makes thisness redundant in the case of material substances. Nonetheless, I will suggest that a version of the model can be appropriately applied in the case of other individuals which might instantiate thisness: for example, events (where these are conceived as a fundamental category of ontology distinct from material substances).

Richard Swinburne is an emergent dualist. One feature of his view is the need for a “thisness” or haecceity that makes each soul the soul that it is, distinct from other souls that may be indistinguishable from it in all qualitative respects. I argue that there is no need for thisnesses.

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.

My goal in this paper is to address what I call the ‘Incoherence’ objection to the growing universe theory of time. At the root of the objection is the thought that one cannot wed objective temporal becoming with the existence of a tenseless past—which is apparently what the growing universe theorist tries to do. To do so, however, is to attribute both dynamic and static aspects to time, and, given the mutual exclusivity of these two aspects—so the thought goes—incoherence results. (...) My solution to the problem is to offer an alternative account of past existence that is compatible with a dynamic conception of time. I take as my starting point Adams’ suggestion that the past exists in virtue of the existence of thisnesses of past individuals. I first seek to defend this suggestion, before amending it in order to provide a satisfactory response to the Incoherence objection. The result is a new growing universe theory which avoids the Incoherence objection but which has some surprising features of its own. Chief among these is the rejection of present events. I argue, however, that such a rejection is a necessary consequence of endorsing the growing universe theory, and that it is not as counter-intuitive as it initially sounds. (shrink)

Consider the things that exist—the entities—and let us suppose they are mereologically structured, that is, some are parts of others. The project of ontology within the bounds of bare mereology use this structure to say which of these entities belong to various ontological kinds, such as properties and particulars. My purpose in this paper is to defend the most radical section of the project, the mereological theory of the exemplification of universals. Along the way I help myself to several hypotheses: (...) the existence of merely possible worlds; that particulars have thisnesses; and that mereology is far from classical. Moreover, the way I characterize instantiation might be judged too complicated to be plausible. At the end of the paper, I reply to these objections based on complexity. (shrink)

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.

We demonstrate that the quantum-mechanical description of composite physical systems of an arbitrary number of similar fermions in all their admissible states, mixed or pure, for all finite-dimensional Hilbert spaces, is not in conflict with Leibniz's Principle of the Identity of Indiscernibles (PII). We discern the fermions by means of physically meaningful, permutation-invariant categorical relations, i.e. relations independent of the quantum-mechanical probabilities. If, indeed, probabilistic relations are permitted as well, we argue that similar bosons can also be discerned in all (...) their admissible states; but their categorical discernibility turns out to be a state-dependent matter. In all demonstrated cases of discernibility, the fermions and the bosons are discerned (i) with only minimal assumptions on the interpretation of quantum mechanics; (ii) without appealing to metaphysical notions, such as Scotusian haecceitas, Lockean substrata, Postian transcendental individuality or Adamsian primitive thisness; and (iii) without revising the general framework of classical elementary predicate logic and standard set theory, thus without revising standard mathematics. This confutes: (a) the currently dominant view that, provided (i) and (ii), the quantum-mechanical description of such composite physical systems always conflicts with PII; and (b) that if PII can be saved at all, the only way to do it is by adopting one or other of the thick metaphysical notions mentioned above. Among the most general and influential arguments for the currently dominant view are those due to Schrodinger, Margenau, Cortes, Dalla Chiara, Di Francia, Redhead, French, Teller, Butterfield, Giuntini, Mittelstaedt, Castellani, Krause and Huggett. We review them succinctly and critically as well as related arguments by van Fraassen and Massimi. (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.

I argue that the semantic thesis of direct reference and the meta- physical thesis of the supervenience of the non-physical on the physical cannot both be true. The argument first develops a necessary condition for supervenience, a so-called conditional locality requirement, which is then shown to be incompatible with some physical object having object dependent properties, which in turn is required for the thesis of direct reference to be true. We apply this argument to formulate a new argument against the (...) claim that a thisness is analyzable in purely general terms, one that does not rely on complete symmetry nor the falsity of the identity of indiscernibles. I outline a strategy at the end how the conclusion could be avoided, at a price. (shrink)

We maximally extend the quantum‐mechanical results of Muller and Saunders ( 2008 ) establishing the ‘weak discernibility’ of an arbitrary number of similar fermions in finite‐dimensional Hilbert spaces. This confutes the currently dominant view that ( A ) the quantum‐mechanical description of similar particles conflicts with Leibniz’s Principle of the Identity of Indiscernibles (PII); and that ( B ) the only way to save PII is by adopting some heavy metaphysical notion such as Scotusian haecceitas or Adamsian primitive thisness. (...) We take sides with Muller and Saunders ( 2008 ) against this currently dominant view, which has been expounded and defended by many. *Received July 2008; revised May 2009. †To contact the authors, please write to: F.

This paper consists of my responses to the comments by nine commentators on my book Are we Bodies or Souls? It makes twelve separate points, each one relevant to the comments of one or more of the commentators, as follows: I defend my understanding of “knowing the essence” of an object as knowing a set of logically necessary and sufficient conditions for an object to be that object; I claim that there cannot be thoughts without a thinker; I argue that (...) my distinction of “mental” from “physical” events in terms of whether anyone has privileged access to whether or not they occur, is a clear one; and I defend my account of metaphysical modality and its role in defending my account of personal identity; I defend my view that Descartes’s argument in favor of the view that humans are essentially souls fails, but that my amended version of that argument succeeds; I claim that my theory acknowledges the closeness of the connection in an earthly life between a human soul and its body; I argue that my Cartesian theory of the soul-body relation is preferable to Aquinas’s theory of that; I argue that a material thing cannot have mental properties; I argue that any set of logically necessary conditions for an object to be the object it is, which together form a logically sufficient condition for this, mutually entails any other such set; I deny that a dualist needs to provide an explanation of how the soul has the capacities that it has; and finally I defend my view that souls have thisness, and claim that that is not a difficulty for the view that God determines which persons will exist.

The mathematical notion of a permutation of indices in the state description admits different physical interpretations. Two main interpretations analyzed in this paper are: exchange of essences and exchange of haecceities. It is argued that adopting the essentialist approach leads to the conclusion, contrary to the conventional wisdom, that quantum particles of the same type are sometimes discernible by their properties. The indiscernibility thesis can be supported only by the alternative interpretation in terms of primitive thisness.

If, as I have argued elsewhere, consequentialism is not fundamentally concerned with such staples of moral theory as rightness, duty, obligation, moral requirements, goodness (as applied to actions), and harm, what, if anything, does it have to say about such notions? While such notions have no part to play at the deepest level of the theory, they may nonetheless be of practical significance. By way of explanation I provide a linguistic contextualist account of these notions. A contextualist approach to all (...) these notions makes room for them in ordinary moral discourse, but it also illustrates why there is no room for them at the level of fundamental moral theory. If the truth value of a judgment that an action is right or good varies according to the context in which it is made, then rightness or goodness can no more be properties of actions themselves than thisness or hereness can be properties of things or locations themselves.

Advocates of the A-Theory of time argue that pastness, presentness and futurity are mind-independent properties of events on the grounds that tensed and tenseless sentences are not semantically equivalent. However, their arguments for semantic nonequivalence do not entail state of affairs nonequivalence, and this latter nonequivalence must also obtain in order for the A-Theory to be true. The situation is like arguing that hereness and thisness are extra, mind-independent properties of places and objects on the grounds that sentences in (...) which "here" and "this" are used do not mean the same as their referential counterparts. Since we are not tempted to say that hereness is an extra property of places because of this semantic nonequivalence, we should not be tempted to say that presentness is an extra property of events because of the semantic nonequivalence of tensed and tenseless sentences.

This article seeks to introduce a greater degree of precision into our understanding of Madhyamaka Buddhist ontological non-foundationalism, focussing specifically on the Madhyamaka founder Nāgārjuna (c. 150–250 CE). It distinguishes four senses of what the ‘foundation’ whose existence Mādhyamikas deny means; that is, (1) as ‘something that stands under or grounds things’ (a position known as generic substantialism); (2) as ‘a particular kind of basic entity’ (specific substantialism); (3) as ‘an individual essence (a haecceity or thisness of that object) (...) by means of which it is identical to that very object, to itself’ (modal essentialism); and (4) as ‘an essence in the absence of which an object could be of a radically different kind or sort of object than it in fact is’ (sortal essentialism). It then proceeds to delineate the Madhyamaka refutation of the specific substantialist position in terms of its argued denial of dharma as basic entity; of generic substantialism and modal essentialism in terms of its argued denial of svabhāva as both foundation for and essence of putative entities; and of sortal essentialism in terms of its argued denial of essentialist conceptions of conceptual thought (vikalpa), mental construction (prapañca), and in short the entire domain of ratiocination (kalpanā), by means of its notion of conceptual imputation (prajñaptir upādāya)—a denial strictly speaking ontological, but of what are putative epistemic entities. The final portion of the article explains the relationship of ontological to other forms of non-foundationalism according to Madhyamaka. (shrink)

According to the TDT, no singular propositions about an individual and no "thisnesses" of individuals exist prior to the existence of the indivi­dual in question, where a thisness "is the property of being x, or of being identical with x" and a "singular proposition about an individual x is a proposition that involves or refers to x directly, perhaps by having x or the thisness of x as a constituent, and not merely by way of x's qualitative properties (...) or relations to other individuals" (p. 315) The support for this position comes from two sources, according to Adams.

The question of the principle of individuation in current analytical philosophy was the subject of medieval discussions, too, in which not only similar proposals of solutions emerged, but also dilemmas invoked by the set of then-discussed proposals appeared. Duns Scotus criticizes the previous theories of individuation and suggests that the difficulties could be avoided by changing the viewpoint from the categorical-quiditative to the transcendental-modal understanding of the principle of individuation. Scotus’ solution is close to the theory of naked substrates, because (...) the substrate and “thisness” act as individuators with modal character. From the relecture of Scotus’ modal understanding of the principle of individuation may arise inspirations that need to be considered in comparison with modern analytical theories of individuation and thus they can be enriched.

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 43.4 (2005) 490-491 [Access article in PDF] Husain Sarkar. Descartes' Cogito: Saved from the Great Shipwreck. New York: Cambridge University Press, 2003. Pp. xviii + 305. Cloth, $65.00. Descartes's first critics attacked his cogito, ergo sum as deficient; his present critics attack it as excessive. Either way, it is an Archimedean point in Descartes's world and merits a book-length study. In this book, (...) Husain Sarkar makes a powerful case that the cogito is not an argument, but rather an "experiment," generating an intuition enabling Descartes to retrieve a timber from what Bourdin called the "great shipwreck" of the hyperbolic doubt.Sarkar places the experiment within his own fresh readings of Descartes's philosophy. They will be illuminating to new Descartes scholars. Some readings will seem perverse or cryptic. Constructive passages illuminate more, polemic passages less, as when Sarkar finds seven flaws in Hintikka's cogito interpretation. Despite the polemic excesses, Sarkar writes with modesty, epitomized by his slogan, "Reason with them in the most courteous manner."With verve and imagination Sarkar presents the cogito as an experiment which can be carried out in any world at all and yields an intuition that qualifies as a Cartesian first principle. He suggests various implications of his interpretation—for example, for the epistemic role of will: "The will initially learns the limits that it must recognize only at the foot of the cogito... It is in the state of the cogito that the will learns what it means to be ineluctably inclined toward affirming a proposition, and what it is to be free" (256).What is the content of the intuited 'I exist'? Sarkar calls upon Robert Adams's notion of a "primitive thisness," entirely distinct from a substance's properties or "suchnesses," and upon David Lewis's thesis that besides knowing propositions a person can know a self-ascription of a property. Still, he makes no headway at all. True, the question is extraordinarily [End Page 490] difficult. It has not yielded appreciably to brilliant phenomenologists or brilliant students of direct reference and indexicality or, for that matter, me. The content of 'I' statements is a topic for another book, and no one I know of is writing it.In the book's centerpiece, Sarkar marshals a series of attacks on the cogito as argument. Sometimes they miss—more polemic overkill. Usually they hit home. Their cumulative effect is persuasive.Descartes says that "I think, therefore I exist" is the first principle of his philosophy (VI, 32; VIIIA, 7; V, 147: references are to the Adam and Tannery edition). But if the cogito were an argument, one of its premises would become his first principle.An argument requires movement of thought and that requires reliance on memory (X, 370 and 408), and in the cogito Descartes strips memory of its credentials (VII, 24, superseding the assurances of X, 368).An argument relies on logical principles, but Descartes suspects these and reasoning generally. In the First Meditation he calls into doubt the simplest mathematics; elsewhere he generalizes from mathematics to "self-evident principles" and to "all the arguments I had previously taken as demonstrative proofs" (VI, 32; IXB, 6; similar aspersions are cast in V, 137 and 139). (But see also Mark Olson, "Descartes' First Meditation: Mathematics and the Laws of Logic" JHP 26 [1988]: 407–438.)I'll add a wrinkle. Descartes's mouthpiece Eudoxus says you can use your own doubt to deduce facts that are even more certain than those commonly built upon the great principle that it is impossible that a thing should both exist and at the same time not exist (X, 522). The conclusion of any argument rests on such logical principles. If the cogito were an argument, its certainty could not exceed theirs. Descartes suggests here that it does.Sarkar also cites Descartes's denigrations of "logic," but these often pertain not to reasoning generally but to syllogistic logic. Thus Margaret Wilson took the cogito to be a nonsyllogistic argument. Still, Sarkar effectively deploys... (shrink)

In this new book, Marko Zlomislić argues that Slavoj Žižek's work does not contain any sort of radical emancipatory project, especially as it passes through the ideology of communism and Lacanian psychoanalysis. The evidence for the failure of communism is vast and includes the more than six hundred mass graves recently located in Žižek's homeland of Slovenia. Zlomislić demonstrates that the way out of the capitalist dilemma is not a repetition of communism but a return to the late medieval notion (...) of haecceity or "individual thisness" that was rejected by modernity. Haecceity, or the indescribable and indefinite here and now of the person, shows that the late medieval Franciscans were already "postmodernists." It is no wonder that the totalitarianism of the modernist Hegel is embraced by thinkers such as Žižek, Badiou, Hardt, Negri, and Laclau and was already rejected by Leibnitz, Kierkegaard, Nietzsche, Levinas, Deleuze, and Derrida. This important book shows that Žižek's work must be rejected because it does not uphold the dignity, worth, and uniqueness of the person. (shrink)

The identity of indiscernibles is false. Robert Adams and others have argued that if the identity of indiscernibles is false, then primitive thisness must be admitted as a fundamental feature of the world (i.e. haecceitism is true). Moreover, it has been suggested that if haecceitism is true, then essentialism is false - that accounting for individuation by means of haecceities precludes a thing's having essential qualitative properties. I will argue that this suggestion is misguided. In so doing, I will (...) be defending what Adams has labeled 'moderate haecceitism'.After working through some preliminary issues, I will attempt (in section I) to motivate haecceitism. I will begin by reviewing Adams' arguments against the doctrine of the identity of indiscernibles. Next, I will examine altemative accounts of individuation which concede the falsity of that doctrine. I will reject these accounts and conclude that primitive thisness has an essential role to play in any satisfying account of individuation. In section II, I will surface the alleged tension between haecceitism and essentialism. In section III, I will suggest that Adams' moderate haecceitism avoids the tension surfaced in section II. Finally, in section IV, I will raise a difficulty for Adams' view and suggest a different understanding of the nature of haecceities. I will argue that the alleged tension between haecceitism and essentialism rests on a conflation of the metaphysical problem of individuation either with the epistemological problem which goes by the same name or with problems involving the unity of a thing. I will conclude with a few brief comments about the significance of moderate haecceitism for modal epistemology. (shrink)

Should Christians support the view that one’s psychological continuity is the main criterion of personal identity? Is the continuity of one’s brain or memory states necessary and sufficient for the identicalness of the person? This paper investigates the plausibility of the psychological continuity theory of personal identity, which holds that the criterion of personal identity is certain psychological continuity between persons existing at different times. I argue that the psychological continuity theory in its various forms suffers from interminable problems. Then, (...) I introduce an alternate account of personal identity, according to which personal identity is not further analyzable in terms of qualitative properties of persons. Rather, persons are individuated by their primitive thisnesses, which are nonqualitative properties of immaterial substances. This alternate conception of personal identity would be of particular relevance to those who believe in the immortality of the soul and are looking for a nonphysicalist account of personal identity.

The way in which vision represents objects as being the same despite movement and qualitative changes has been extensively investigated in contemporary psychology. However, the formal properties of the visual sameness relation are still unclear, for example, whether it is an identity-like, equivalence relation. The paper concerns one aspect of this problem: the transitivity of visual sameness. Results obtained by using different experimental paradigms are analysed, in particular studies using streaming/bouncing stimuli, multiple object tracking experiments and investigations concerning object-specific preview (...) benefit, and it is argued that the transitive interpretation of visual sameness is the most plausible given the current stage of knowledge. What is more, it is claimed that the way in which visual sameness is represented suggests that in some cases it should be characterized as a “primitive sameness”, similarly as in philosophical theories postulating “thisness”.

With the challenges from science, there has been a shift away from traditional or classical versions of substance dualism toward emergentist accounts of the mind. Of particular importance for those still inclined to make some distinction between the mind and brain, emergent substance dualism provides an attractive option. However, it promises more than it can deliver. In the present article, I show that a version of emergent substance dualism, where the brain produces a soul, lacks the resources to account for (...) the particularity of the soul. I show that, if, in fact, souls have primitive thisness, then physical laws could not produce these souls. That being the case, I show how creationism and emergent substance dualism, rather than being disjunctive options, are compatible. In the end, what I call emergent-creationism or creationist-emergentism provides an attractive theory of the origin of souls. (shrink)

In his paper Bare Particulars, T. Sider claims that one of the most plausible candidates for bare particulars are spacetime points. The aim of this paper is to shed light on Sider’s reasoning and its consequences. There are three concepts of spacetime points that allow their identification with bare particulars. One of them, Moderate structural realism, is considered to be the most adequate due its appropriate approach to spacetime metric and moderate view of mereological simples. However, it pushes the Substratum (...) theory to dismiss primitive thisness as the only identity condition for bare particulars, but the paper argues that such elimination is a legitimate step.

According to the presentist, only the present moment exists and, as time passes, what’s present changes. However some argue that, if only one moment exists, the presentist cannot explain the passage of time. While the presentist historically appeals to surrogates—proxies which exist in the present but play the role of non-existent past times—to evade this sort of worry, the appeal to surrogates has come under renewed attack from Lisa Leininger. But hope is not lost for the presentist. I argue that (...) presentists do have the resources available to address the underlying issue Leininger articulates. Moreover, there’s disagreement amongst presentists about which version of presentism is best. For instance, David Ingram has recently argued that thisness presentism is preferable to other versions of presentism because it’s able to handle certain problems other versions of presentism cannot. However, I argue that this assessment is premature. More specifically, I argue that Ingram’s response to an objection from Lisa Leininger fails to address the core issue she raises. Consequently, I argue that presentists shouldn’t embrace thisness presentism just yet. In this way, my aims here are to: sharpen Leininger’s objection, highlight tenable presentist replies to it, and advance the discussion about which version of presentism should be favoured. (shrink)

This article highlights five areas of Scotus' philosophy that have recently been the subject of scholarly discussion. (1) Metaphysics : I outline the most current accounts of Scotus on individuation (thisness or haecceity) and the common nature. (2) Modal theory : I consider recent accounts both of Scotus' innovations in spelling out the notion of the logically (and broadly logically) possible, and of his account of the independence of modality. (3) Cognitive psychology : I examine recent views of Scotus' (...) theory of intentionality and the nature of mental content. (4) Semantics : I look at contemporary expositions of Scotus' view that words signify things. (5) Metaethics and ethics : I briefly describe conflicting interpretations of Scotus' metaethics, and discuss whether Scotus should be thought of as adopting some kind of divine-command theory or not. I note too Scotus' claim that virtues and passions can be located in the will. (shrink)

In this paper, I am going to ask what the general criteria for identity are and exactly how essence is related to that. Two notions are related to this question: Essential properties (necessary properties) and individual essences. Only the notion of individual essence has been involved in the criteria of transworld identity. The disputes of transworld have centered on the intrinsic properties necessarily connected to thisness. Through introducing a notion of part-rigidity, however, we can see that there can be (...) an entity that does not have an individual essence as an intrinsic property necessarily connected to thisness, the non-part-rigid structure. Being this structure is an intrinsic property that is relational and compositional. An entity that has a relational and compositional intrinsic property as its necessary property seems to have no individual essence. For this kind of entities, just an essential property (or a necessary property) is involved in the criteria of transworldidentity. (shrink)

This paper addresses two issues in Richard Swinburne’s book Are We Bodies or Souls? I interpret Swinburne’s modal argument as an example of a priori synthetic knowledge. Swinburne’s thesis that every person possesses “thisness” is compared with Kant’s distinction between the empirical character and the intelligible character.

In lieu of an abstract, here is a brief excerpt of the content:Particularity, Presence, Art Teaching, and LearningJulia Kellman (bio)The Awful, the Particular, and the TranscendentYears ago in a life drawing class during graduate school, for who knows what reason, I chose to focus my drawing on the model's head and not on her entire form. She was wearing an enormous and elaborate black velvet hat with yards of veiling and several large red silk roses. The combination of textures, shadows, (...) colors, forms, and the suggestion of a story, of meaning beyond the exercise itself, drew me in I think. Using an entire large sheet of tan-colored drawing paper, soft vine charcoal, and a kneaded rubber eraser I began to draw, moving from the impossible hat to the model's high cheekbones, deep-set shadowed eyes, soft cheeks, and curved neck. Somewhere between the top of the paper (the crown of her hat) and the woman's face, however, my hand, my self, the drawing, the young woman, and the hat merged by some means outside my control. I was the act of drawing. I was the charcoal, the curved cheek, the dark eyes, the wonderful hat. There were no boundaries among us. No distances. The drawing, it seemed, drew me at the same time that it revealed an image of the model and her black velvet hat on the paper and tied me to the woman seated before me. I was exalted, transported, amazed.Now, as I think back to that drawing, I understand it as my first clear art experience of doing, not thinking, being, not observing that all artists encounter on their best days. It was, in another way of considering, my initial encounter with the fact that "the imaginative faculty, especially as engaged in the art process is one of the strongest and clearest ways in which we can learn within the qualitative, immediate present, within kairotic as opposed to chronic time, or within the eternal present,"1 as the art educator Kenneth [End Page 51] Beittel explains. Or, put another way, it was my experience with the fact that, as the writer Lawrence Weschler suggests in his biography of the artist Robert Irwin, "Seeing is forgetting the name of the thing one sees."2 Or, as the sculptor Anne Truitt explains, drawing can be "a direct channel between one's [my] experience and one's [my] hand."3This transformation from a distinct see-er and seen to a single entity sharing both time and space, from a distant relationship to intimacy, from a world of the generalized to the place of the particular brings us to the intertwined themes of this article: the importance of the awesome transcendent particularity of the singular—person, creature, place, object, plant, or moment in art and, similarly, religious contemplation and the likeness and/or overlap of artistic engagement with spiritual experience.In order for us to examine the artist in the midst of creating, and to explore our theme of art's relationship to the awful (think of the older usage meaning "full of awe" here) particularity of thisness as John Dun Sotus4 describes the perfection of the particular and specific, as well as to explore the relationship of art making, art learning, art teaching, and spiritual experience, exemplars are necessary. Our first exemplar is Gordie, a member of the art class I teach at a local hospital. He, as much as anyone, exemplifies artistic engagement with the current moment, its thisness in fact, and he illustrates the art maker's/learner's engagement with pure doing in the act of creating an image. Our second exemplar, the filmmaker, writer, and painter Derek Jarman,5 exemplifies by his lifetime of creative accomplishment an artist in the most literal manner. And even in the last years of his life—as sculptor, gardener, landscape designer, writer, and creator of a place of great beauty—he illuminates in both his words and in his garden his engagement with the present moment, with particularity, and with the spiritual quality that permeates his world.Gordie's Tale: Art and FlowersGordie accompanied his friend Roger to the first art class to be held at the hospital for people with...

In this paper, I want to draw attention to a connection between rigid designation with its consequence that we are able to stipulate worlds and haecceitism, the doctrine that we have possible worlds alike in all qualitative features which nonetheless are metaphysically different, in that two individuals can have all their qualitative features swapped while remaining the same individuals. I shall argue that stipulation leads to haecceitism, which in turn depends upon commitment to haecceity ("primitive thisness"). Haecceitism is, I (...) claim, an unattractive doctrine, but there is one powerful argument for it, drawn from the desire to make sense of observed frequencies of probabilistic events in terms of possible configurations of phase spaces which may be taken to be a form of possible world. However, by paying close attention to classical and quantum statistics, we see that this argument fails. (shrink)

The attempt by Arnason and Roberts to interpret Canetti’s work in the context of social theory is taken here as the point of departure to investigate Canetti’s view on the phenomenon of resistance. Resistance is explored in the context of Canetti’s reflection on power and transformation. Further, it is argued that through his substantive concern for crowds, an epistemological challenge emerges for social theory. Canetti gives us some precious insights on phenomena of ambiguous multiplicity, which are neither simple sums of (...) separate individuals nor an ontologized Durkheimian collective. Not only this, he resolutely ventures towards the contingency at the foundation of social order, the ‘just-thisness' of power, revealing its non-symbolic basis in gestures that impart affects. It is at this level that resistance can be best understood as a movement of liberation from the grip of power. (shrink)

This book explains how Duns Scotus's concept of 'Haecceitas'—thisness, or individuation—represents an insufficiently recognized yet central aspect of Aristotelianism, namely its denial of and flight from 'the play of difference' that was a core aspect of Plato's philosophy.

This is one of the most philosophically interesting books on Leibniz published in the last years: it is highly rewarding not only for Leibniz scholars, but also for people interested in typical issues of contemporary analytic philosophy like transworld identity, the identity of indiscernibles, the contrast between suchness and thisness, etc. It is even a quite demanding book: clearly written and well argued, it discusses at length, in rigorous analytical style, many philosophical topics, raising several questions and suggesting original (...) answers.

In lieu of an abstract, here is a brief excerpt of the content:258 HISTORY OF PHILOSOPHY To make this theme conspicuous to the reader, the author deals with three topics in Aristotle's first philosophy: the path from beings to the primary instance of being, the study of sensible substance, and the distinction between the potential and the actual. Grene's essay on the most perplexing of Aristotle's works is the least satisfactory in her study. Though she acknowledges that the path of (...) thg Aristotelian first philosopher is not easy, her analysis of the school X67oLmakes the road more facile than it, in fact, is. For example, what is the relation between Wisdom (the science of principles and causes), the science of being-qua-being, and the science of immovable substance? How can the latter be universal and, at the same time, have as its object one kind of being? Why does Aristotle dismiss substrate in the sense of compound of form and matter as a candidate for substance? It would seem to satisfy his criteria of thisness and separability better (or at least in more instances) than substrate in the sense of form. Finally, it is hard to avoid Ross's conclusion (Aristotle's Metaphysics, Vol. 1, pp. ci) that Aristotle in Book Z moves away from the view that the primary ontological units are sensible individuals toward the view that they are pure forms. The real is either the object of definition (and this appears to be Aristotle's view for the most part in Book Z) or it is the individual (the doctrine of the Categories); it cannot, on Aristotelian grounds, be both. Grene's resolution of the difficulty will not bear scrutiny. She says (p. 205): "Definition is of the universal. But the object of definition is the real substance, the being-what-it-is of the thing. This is substance and not universal." The incompatibility of the first and third sentences in this passage constitutes what Grene refers to (p. 205) as "a very perplexing situation indeed;" and they also reflect the "double meaning" which "pervades Aristotle's whole treatment of substance" (Ross, Aristotle, p. 166). It is the doctrine of the first sentence which comes to the fore in Book Z, for there Aristotle concludes (i) that ot~r is r6 I"L~Tv e~tL and maintains (ii) that rb rl ~v rival 'will belong to nothing which is not a species of a genus' (1030"12-13). And we hardly need be reminded that an Aristotelian species is not an individual. Grene, it seems to me, relieves our perplexity somewhat, but only by blurring the oscillation in Aristotle's mind on this point, e.g., when she implies that the unambiguous doctrine of Book Z is that "as far as the perceived world goes, the naturalist's specimen, the individual of a type, the member of a class, is the prototype of the real" (p. 205). In very readable prose Grene has given us a picture of Aristotle that is at once engaging and in most respects faithful to the interests and outlook of her model. She says in a bibliographical note that her book is "meant more for the undergraduate reader or the general public than for scholars already conversant both with the text and the tradition" (p. 257). I suggest that the account Grene has given us is stimulating and refreshing also for the scholar. JosxAtt B. GOULD,JR. Glaremont Graduate School La filosofia medievale: Antologia di testi.
