The most common form of endurantism takes enduring objects to be wholly located at every time they occupy. Such a view is believed to give rise to a problem concerning intrinsic change. My laptop may have been shut before, but it is currently open. Yet, if we understand endurantism as above, then my laptop is in possession of two contradictory properties: the shapes of being open and shut. This problem is known as the “problem of temporary (...) intrinsics,” and, to avoid it, two major kinds of moves have been made. The first is to meddle with the relationship between an enduring object and its properties by, for instance, claiming enduring objects bear their properties relationally to times rather than intrinsically. Many who have found this move unappealing have instead turned to presentism, claiming that endurantists should be presentists to avoid the problem. I take it that while both options can work, neither is optimal. Instead, I argue in favor of an alternative understanding of endurantism that allows endurantists to have it all: there is a version of endurantism that leaves the intrinsic properties of objects untouched, avoids the problem of temporary intrinsics, and does not require adopting presentism. (shrink)

It is standardly assumed that there are three — and only three — ways to solve problem of temporary intrinsics: (a) embrace presentism, (b) relativize property possession to times, or (c) accept the doctrine of temporal parts. The first two solutions are favoured by endurantists, whereas the third is the perdurantist solution of choice. In this paper, I argue that there is a further type of solution available to endurantists, one that not only avoids the usual costs, (...) but is structurally identical to the temporal-parts solution preferred by perdurantists. In addition to providing a general characterization of this new type of solution, I discuss certain of its anticipations in the literature on bundle theory, as well as provide a detailed development of it in terms of my own preferred metaphysics of ordinary objects — namely, a distinctive form of substratum theory tracing to Aristotle.

David Lewis uses the problem of temporary intrinsics to motivate a perdurantist account of persistence in which four-dimensional individuals consist of temporal parts. Other philosophers use his argument to conclude that apparently persisting individuals are collections of temporal stages. In this paper, I investigate whether this argument is as effective in an ontology in which properties are causal powers and thus how seriously the problem should be taken. I go back to first principles to examine the (...) ways in which individuals can change within an ontology of powers and then consider whether any of these ways are compatible with Lewis’s problem. I conclude that if powers are intrinsic, they are not temporary; and if they are temporary, they are not fully intrinsic. However, the situation with respect to changes in which powers are manifesting is not so clear cut, and so I explore how different conceptions of manifestation affect whether the problem of temporary intrinsics applies and what the powers theorist may say about them.

McTaggart’s Paradox has been considered a special case of Lewis’s Problem of Temporary Intrinsics (see Craig (1998), Rea (2003) and Rettler (2012)). I argue instead that the Problem of Temporary Intrinsics cannot simply be applied to the Problem of the passage of time and therefore that McTaggart’s Paradox cannot be a special case of the Problem of Temporary Intrinsics. This observation is relevant in order to point out the difference between (...) the change in objects or events over time (i.e. the subject of Lewis’s Problem) and the change (or passage) of time (i.e. the subject of McTaggart’s Paradox). (shrink)

It has been argued that there is a problem oftemporary intrinsics, the problem of explaininghow it is possible for things to possesssuccessively contrary properties, if a certaintheory about time, ``eternalism'', is true. Inthis paper, I consider whether there really issuch a problem and survey some standardsolutions to it. I argue for one of them, onewhich has been offered by Mark Johnston andPeter van Inwagen, and which I call the``exemplification-solution''''. I consider avariant on that solution offered by (...) E.J. Lowe(and Sally Haslanger), and I argue that thisvariant should be rejected. (shrink)

In this paper I show that the problem of temporary intrinsics and a fundamental philosophical problem concerning the doctrine of the incarnation are isomorphic. To do so, I present the problem of temporary intrinsics, along with five responses to the problem. I then present the fundamental problem for Christology, which I call the problem of natural intrinsics. I present six responses to that problem, all but the last analogous (...) to a response to the problem of temporary intrinsics. My goal is not to argue that any individual response to either problem is correct. Instead, my goal is to present and defend an interesting and unnoticed similarity between two different problems, and to note how work on one problem can help with work on the other. -/- This is a penultimate manuscript, and not a final version, of a forthcoming article in Oxford Studies in Philosophy of Religion.

In this paper I consider an objection that friends of the Metaphysic of Temporal Parts (MTP) press against other solutions to the problem of temporary intrinsics and turn it against the MTP itself. I do not argue that the MTP must be false, nor do I argue that there are no arguments in favor of the MTP. Rather, the conclusion I draw is conditional: if the MTP provides an adequate response to the problem of temporary (...) intrinsics, then the MTP provides no reason to reject our commonsense view of the nature of material objects. (shrink)

The problem of temporary intrinsics is the problem of how persisting objects can have different intrinsic properties at different times. The relativizer responds to this problem by replacing ordinary intrinsic properties with relations to times. In this note, I identify and respond to three different objections to the relativizer's proposal, each of which can be traced to the work of David Lewis.

Some have concluded that the only appropriate response to the problem of temporary intrinsics is the view that familiar, concrete objects persist through time by perduring, that is, by having temporal parts. Many, including myself, believe this view of persistence is false, and so reject this conclusion. However, the most common attempts to resolve the problem and yet defend the view that familiar, concrete objects endure are self-defeating. This has heretofore gone unnoticed. I consider the most (...) familiar such attempts, based on a strategy called tensing the copula , and present a general argument to demonstrate why this strategy – and any strategy based on relativization – fails. I then show how the considerations raised in this general argument undermine other attempts to resolve the problem while denying perdurance. All these attempts are undermined by an assumption essential to the problem of temporary intrinsics, to wit, that there are many moments of time and all have the same ontological status. As long as this assumption is maintained, the only solution to the problem is that familiar, concrete objects perdure. Thus, in order to defend the view that objects persist through time by enduring, one must adopt a different metaphysics of time (viz., presentism). I conclude that it is neither unreasonable nor impracticable to do so. (shrink)

This is an attempt to sort out what is it that makes many of us uncomfortable with the perdurantist solution to the problem of change. Lewis argues that only perdurantism can reconcile change with persistence over time, while neither presentism nor endurantism can. So, first, I defend the endurantist solution to the problem of change, by arguing that what is relative to time are not properties, but their possession. Second, I explore the anti-perdurantist strategy of arguing that Lewis (...) cannot solve the problem of change, for he cannot account for how some properties are possessed by objects in time. However, I argue that this strategy fails, for if by saying that objects in time can have properties ‘timelessly’ we mean “at no particular time” and “tenselessly”, only objects outside time can have properties in that way; but if we mean “for all the time they exist”, or “essentially”, perdurantists can account for this. Finally, I argue that actually perdurantism cannot solve the problem, but for different reasons: for either it sweeps the problem under the carpet, denying change, and in general subverting our conceptual scheme in a dangerous way, or it becomes equivalent to the endurantist picture that properties are had at times. Nor perdurantism is justified by the Relativity Theory or the B-theory of time, because while endurantism is certainly comfortable with presentism, it need not be committed to it; and even if it were, presentism need not be refuted by the Relativity Theory. (shrink)

We find that E. J. Lowe’s resolution to David Lewis’s problem of temporary intrinsics is wrong, but not quite for the reasons adduced by Lewis himself. Our discussion hinges on a connection between state-independent properties and intrinsic properties.

I discuss the general form of arguments that profess to prove that the view that things endure in tensed time through causally produced change (the dynamic view) must be false because it involves contradictions. I argue that these arguments implicitly presuppose what has been called the temporal parity thesis, i.e. that all moments of time are equally existent and real, and that this thesis must be understood as the denial of the dynamic view. When this implicit premise is made explicit, (...) the arguments turn out to be either circular, they presuppose what they profess to prove, or mere demonstrations of the fact that the dynamic view is incompatible with its own negation. Furthermore, I discuss the metaphysical consequences of accepting the temporal parity thesis, arguing that it deprives us of the means to provide natural explanations to empirical phenomena.

Take this banana. It is now yellow, and when I bought it yesterday it was green. How can a single object be both green all over and yellow all over without contradiction? It is, of course, the passage of time which dissolves the contradiction, but how is this possible? How can a banana ripen? These questions raise the problem of change. The problem is sometimes called the problem of temporary intrinsics, but, as I shall explain (...) below, this emphasis on intrinsic properties is misleading. For my more recent thoughts in this area, please see my 'David Lewis on Persistence' (2015). (shrink)

In this paper, I show how a solution to Lewis’ problem of temporary intrinsics is also a response to McTaggart’s argument that the A-series is incoherent. There are three strategies Lewis considers for solving the problem of temporary intrinsics: perdurantism, presentism, and property-indexing. William Lane Craig (Analysis 58(2):122–127, 1998) has examined how the three strategies fare with respect to McTaggart’s argument. The only viable solution Lewis considers to the problem of temporary (...) class='Hi'>intrinsics that also succeeds against McTaggart, Craig claims, is presentism. This gives us prima facie reason to be presentists. But there is a strategy Craig does not consider-indexing, or relativizing, the copula. In this paper, I show that to the degree that indexing the copula solves the problem of temporary intrinsics, it also shows the invalidity of McTaggart’s argument. The upshot: the copula-indexer needn’t affirm the unreality of time, nor need she embrace presentism. (shrink)

Most people who believe in temporal parts believe that the referents of our ordinary referring terms, like Bill Clinton, or that table, are fusions of temporal parts from past, present and future times. Call these fusions worms, and the theory that the referents of ordinary referring terms (ordinary objects) the worm theory. Buying the metaphysical theory of temporal parts does not immediately imply that we must buy the worm theory. Theodore Sider (1996, 2000), for example, has suggested that these ordinary (...) referring terms just pick out a single, instantaneous, temporal part. Sider’s theory, called the stage theory, solves some pressing philosophical problems, including the problem of temporary intrinsics. But the stage theory has several difficulties of its own, especially what I will call the problem of long-term intrinsics. I argue for a rival theory, the growing individuals theory. On this theory, the referents of our ordinary referring terms have past and present temporal parts, but not future temporal parts. This theory best accounts for our intuitions about which intrinsic properties ordinary objects have. (shrink)

Two recurrent arguments levelled against the view that enduring objects survive change are examined within the framework of the B-theory of time: the argument from Leibniz's Law and the argument from Instantiation of Incompatible Properties. Both arguments are shown to be question-begging and hence unsuccessful.

Our world is a world of change. Children are born and grow into adults. Material possessions rust and decay with age and ultimately perish. Yet scepticism about change is as old as philosophy itself. Heraclitus, for example, argued that nothing could survive the replacement of parts, so that it is impossible to step into the same river twice. Zeno argued that motion is paradoxical, so that nothing can alter its location. Parmenides and his followers went even further, arguing that the (...) very concept of qualitative change is inconsistent. Change in any respect is impossible, they argued, as change requires difference and nothing differs from itself. Few today would accept the Eleatic conclusion that change is impossible. But the topic of change continues to be a source of much debate, as it brings together various issues that are central to metaphysics, language, and logic – including identity, persistence, time, tense, and temporal logic.

The philosophy problem of identity and the related problem of change go back to the ancient Greek philosophers and fascinated later figures including Leibniz, Locke and Hume. Heraclitus argued that one could not swim in the same river twice because new waters were ever flowing in. When is a river not the same river? If one removes one plank at a time when is a ship no longer a ship? What is the basic nature of identity and persistence? (...) This book introduces and asseses the philosophical puzzles posed by things persisting through time. Beginning with essential historical background to the problem it explores the following key topics and debates: mereology and identity, including 'Leibniz's Law' the constitution view of identity the 'relative identity' argument concerning identity temporary identity four-dimensionalism, counterpart and mulitiple counterpart theory supervenience the problem of temporary intrinsics the necessity of identity presentism ontological and epistemological criteria for persistence and the difference between them. Including chapter summaries, annotated further reading and a glossary this book is essential reading for anyone seeking a clear and informative introduction to and assessement of the metaphysics of identity.

The A-theory of time is plagued by certain standard armchair problems: the presentism–eternalism dilemma, the problem of truth-makers, the alleged impossibility of cross-temporal relations, and the problem of temporary intrinsics. These challenges supposedly force A-theories to make incredible claims. I argue that these challenges are not deep antinomies in common sense, but rest on avoidable mistakes. Then I present a new A-theory that shows what’s possible once we move past the old problems. On this proposal, time’s (...) passing is a metaphysically fundamental aspect of reality. I take this to mean that there are fundamental facts like: four hours passed from 8am today until noon. This A-theory also posits fundamental facts about the state of the universe at a time, and about cross-temporal relationships. The proposed metaphysical package attractively articulates our common sense, pre-relativistic conception of time. (shrink)

Eliminativist metaphysicians have recently explored various arguments, including those about over-determination, colocation, the problem of the Many and ontological parsimony, for dispensing with kinds and their token continuants. Further, David Lewis’s missing “real temporary intrinsics” has paved the way to treating the sortal and the modal properties yielding the persistence conditions of continuants as unreal because they are extrinsic. In this paper I show, first, that none of the arguments mentioned above are decisive against the disputed entities. (...) Second, I argue that the sortal/modal properties, while extrinsic, are also real, because they are constitutive of kinds. The general point is that modal conceptualism should not be conflated with a cheap version of semanticism. The position advocated here is based on closing the gap between the metaphysical and the epistemic perspectives.Eliminativistički metafizičari u novije su doba istražili razne argumente, uključujući argumente pretjerane determininacije, kolokacije, problem mnoštva i ontološke štedljivosti, kako bi se riješili vrsta i njihovih primjeraka kontinuanata. Nadalje, Lewisova nedostajuća “stvarna privremena intrinzična svojstva” utrla su put shvaćanju sortalnih i modalnih svojstava koja pružaju uvjete ustrajavanja kontinuanata kao nestvarnih, budući da su ekstrinzična. U ovome članku pokazujem, prvo, da nijedan od spomenutih argumenata ne daje odlučne razloge protiv prijepornih entiteta. Drugo, tvrdim da su sortalna/modalna svojstva, iako su ekstrinzična, također stvarna, budući da su konstitutivna za vrste. Općenito, modalni konceptualizam ne treba brkati s jeftinom verzijom semanticizma. Stajalište koje se ovdje zagovara zasniva se na zatvaranju jaza između metafizičke i epistemičke perspektive.

[Peter Simons] Commonsense ontology contains both continuants and occurrents, but are continuants necessary? I argue that they are neither occurrents nor easily replaceable by them. The worst problem for continuants is the question in virtue of what a given continuant exists at a given time. For such truthmakers we must have recourse to occurrents, those vital to the continuant at that time. Continuants are, like abstract objects, invariants under equivalences over occurrents. But they are not abstract, and their being (...) invariants enables us to infer both their lack of temporal parts and that non-invariant predications about them must be relativized to times. \\\ [Joseph Melia] In this paper I try to eliminate occurrents from our ontology. I argue against Simons' position that occurrents are needed to supply truthmakers for existential claims about continuants. Nevertheless, those who would eliminate occurrents still need some account of our willingness to assert sentences that logically entail their existence. Though it turns out to be impossible to paraphrase away our reference to occurrents, I show that the truthmakers for such sentences are facts that involve only continuants. This is enough to allow us to regard our ordinary talk about occurrents as fictional. Finally, I argue that a proper conception of the underlying temporal facts about continuants can both avoid the problematic tensed theory of time and the problem of temporary intrinsics. (shrink)

Assume, for fun, that temporal parts theory is true, and that some kind of modal realism (perhaps based on ersatz worlds) is true. Within this grand metaphysical picture, what are the ordinary objects? Do they have many temporal parts, or just one? Do they have many modal parts, or just one? I survey the issues involved in answering this question, including the problem of temporary intrinsics, the problem of the many, Kripke's objections to counterpart theory and (...) quantifier domain restrictions. (shrink)

The principal aim of this paper is to defend a certain view about temporary properties from an important objection to that view. More specifically, I will be defending the view that ostensible temporary intrinsic properties are really relations between the things that have those properties and times. The objection is, roughly speaking, that by construing ostensible temporary intrinsics as relations to times, persisting things are impoverished, being clothed only by their essential (and perhaps also their permanent) (...) intrinsic properties. The worry is that the relations to times view moves us towards thinking of persisting particulars as being quite bare. I do not suggest that this is the only difficulty for the relations to times view (in fact, I uncover a potential problem for the view in Section 3), but it is an important one. If the objection is successfully addressed, then a significant obstacle to the relations to times view is overcome. (shrink)

In this paper, I introduce a version of perdurantism called Priority Perdurantism, according to which perduring, four-dimensional objects are ontologically fundamental and the temporal parts of those objects are ontologically derivative, depending for their existence and their identity on the four-dimensional wholes of which they are parts. I argue that by switching the order of the priority relations this opens up new solutions to the too-many-thinkers problem and the personite problem – solutions that are more ontologically robust than (...) standard maximality solutions. I then consider and respond to two initial objections to the view: that it no longer counts as a perdurantist theory and that it reintroduces the problem of temporary intrinsics. I conclude by offering two further advantages of priority perdurantism: that it is consistent with hunky time and with the existence of irreducibly temporally-extended actions, such as those pertaining to deliberative agency.

The recent literature on the nature of persistence features a handful of imaginative cases in which an object seems to colocate with itself. So far, discussion of these cases has focused primarily on how they defy the standard endurantist approaches to the problem of temporary intrinsics. But in this article, I set that issue aside and argue that cases of apparent self-colocation also pose another problem for the endurantist. While the perdurantist seems to have a fairly (...) straightforward account of self-colocation, the endurantist has a hard time saying exactly what it would be for an object to be self-colocated. After introducing this problem and explaining how the perdurantist can circumvent it with little difficulty, I discuss a number of tempting endurantist solutions that ultimately fail. Then I suggest an endurantist solution which I think is more promising, but which requires the endurantist to deny that apparent cases of self-colocation are genuine cases of self-colocation.

In this paper I explore how the tenseless copula is to be interpreted in sentences of the form “a is F at t”, where “a” denotes a persisting, changeable object, “F” stands for a prima facie intrinsic property and “t” for a B-time. I argue that the interpretation of the copula depends on the logical role assigned to the time clause. Having rejected the idea that the time clause is to be treated as a sentence operator, I argue: that if (...) “at t” is thought of as being associated with “a” or “F”, then the tenseless copula is most plausibly read as an “is” simpliciter; and that if “at t” is treated as being associated with the copula, then the tenseless copula is most plausibly understood as expressing a disjunction of tensed copulas. I end the paper by explaining the importance of the issue. I indicate the ramifications interpretation of the tenseless copula has for the so-called problem of temporary intrinsics. (shrink)

This chapter examines David Lewis's view that we are temporal parts of animals. It examines three arguments for the view that persisting things have temporal parts–four‐dimensionalism. One is that it solves the problem of temporary intrinsics. The second is that it solves metaphysical problems about the persistence of material objects without the mystery of constitutionalism–though these solutions require a counterpart‐theoretic account of modality. The third is that it solves problems of personal identity–involving fission, for instance–in an attractive (...) way. It is then argued that according to four‐dimensionalism, the bearers of such properties as thinking and acting are momentary stages, forcing us to choose between saying that we don't strictly think and saying that we don't persist.

ABSTRACTPresentism and endurantism are natural bedfellows: arguments have been mounted from endurantism to presentism and vice versa. I generalise an argument against the compatibility between presentism and endurantism offered recently by Tallant. I then show how to reformulate endurantism so that it is compatible with presentism. I demonstrate that this reformulated version of endurantism can do the same work with respect to the problem of temporary intrinsics as can standard definitions.

How can a persisting object change whilst remaining the same object? Lewis, who frames this as the problem of temporary intrinsics, presents us with the perdurance solution: objects persist by having temporal parts which may have differing properties. And in doing so he characterises the opposing view as persisting but not by having temporal parts – a view he calls endurance. But this dichotomous picture of Lewis, although now widely embraced, misses out the orthodox historic view – (...) a view I call temporal holism: objects persist by having temporal parts to which they are ontologically prior. (In the perduring solution, by contrast, the temporal parts are ontologically prior.) This paper sets out this temporal holist solution and makes clear its differences from perdurantist and endurantist solutions. Although temporal holism has a long and illustrious history, this history has not been explicitly recognised. I begin the task of recognising this history in this paper, in order to make clear the nature of temporal holism, and to show that it is a long-established, well supported and distinctive position. The paper sets out, too, how temporal holism solves other ontological problems so that, despite its current neglect, temporary holism has the potential to greatly enrich contemporary philosophical debates.

Not unlike many contemporary philosophers, Leibniz admitted the existence of temporary truths, true propositions that have not always been or will not always be true. In contrast with contemporary philosophers, though, Leibniz conceived of truth in terms of analytic containment: on his view, the truth of a predicative sentence consists in the analytic containment of the concept expressed by the predicate in the concept expressed by the subject. Given that analytic relations among concepts are eternal and unchanging, the (...) class='Hi'>problem arises of explaining how Leibniz reconciled one commitment with the other: how can truth be temporary, if concept-containment is not? This paper presents a new approach to this problem, based on the idea that a concept can be consistent at one time and inconsistent at another. It is argued that, given a proper understanding of what it is for a concept to be consistent, this idea is not as problematic as it may seem at first, and is in fact implied by Leibniz’s general views about propositions, in conjunction with the thesis that some propositions are only temporarily true.

The worst problem for continuants is the question in virtue of what a given continuant exists at a given time. For such truthmakers we must have recourse to occurrents, those vital to the continuant at that time. Continuants are, like abstract objects, invariants under equivalences over occurrents. But they are not abstract, and their being (...) invariants enables us to infer both their lack of temporal parts and that non-invariant predications about them must be relativized to times. \\\ [Joseph Melia] In this paper I try to eliminate occurrents from our ontology. I argue against Simons' position that occurrents are needed to supply truthmakers for existential claims about continuants. Nevertheless, those who would eliminate occurrents still need some account of our willingness to assert sentences that logically entail their existence. Though it turns out to be impossible to paraphrase away our reference to occurrents, I show that the truthmakers for such sentences are facts that involve only continuants. This is enough to allow us to regard our ordinary talk about occurrents as fictional. Finally, I argue that a proper conception of the underlying temporal facts about continuants can both avoid the problematic tensed theory of time and the problem of temporary intrinsics. (shrink)

ABSTRACT Many philosophers believe in the Block Universe containing all objects and events - those that we intuitively call past, present, and future. But some of those who endorse this ontology of time also believe that objects persist by enduring - by being present in their entirety at all moments at which they exist. This combination of views, the Block Universe with Endurance, has survived the initial assault of the problem of temporary intrinsics and of several later (...) objections. But I argue that the Block Universe with Endurance fails to account for a striking feature of our temporal experience and must be rejected in favor of the Block Universe with Exdurance. (shrink)

This paper identifies problems with indexicalism and abverbialism about temporary intrinsic properties, and solves them by disentangling two senses in which a particular may possess a property simpliciter. The first sense is the one identified by adverbialists in which a particular possesses at all times the property as a matter of foundational metaphysical fact regardless of whether it is manifest. The second involves building on adverbialism to produce a semantics for property-manifestation according to which different members of a family (...) of second-order properties of the foundational property are relevant to property manifestation at different times.

According to four dimensionalism, the material world is divided into momentary stages. In a four-dimensional world, which objects are the ordinary things, the things we normally name and quantify over? Aggregates of stages, according to most four-dimensionalists, but according to stage theorists (or exdurantists), ordinary objects are instead to be identified with the stages themselves. (A temporal counterpart theoretic account of de re temporal predication is then given.) This paper argues that a stage theorist is best positioned to accept David (...) Lewis's argument from temporary intrinsics for four-dimensionalism, since stage theorists are the only four-dimensionalists who attribute monadic temporary intrinsic properties to ordinary things.

The Argument from Temporary Intrinsics is one of the canonical arguments against endurantism. I show that the two standard ways of presenting the argument have limited force. I then present a new version of the argument, which provides a more promising articulation of the underlying objection to endurantism. However, the premises of this argument conflict with the gauge theories of particle physics, and so this version of the argument is no more successful than its predecessors. I conclude that (...) no version of the Argument from Temporary Intrinsics gives us a compelling reason to favor one theory of persistence over another. (shrink)

This article poses the hypothesis that the problem of the intrinsic value of nature that stems from the work of G. E. Moore and is widely discussed in environmental philosophy, bas a parallel in a contemporary discussion in semiotics on the existence of semiosis in nature. From a semiotic point of view. value can be defined as an intentional dimension of sign. This is concordant with a biological interpretation of value that relates to biological needs. Thus. a semiotic approach (...) in biology may provide a useful tool for further analysis of the intrinsic value problem in the biological realm. From an ecosemiotic point of view, the problem is also related to the concepts of bioart and ecoart. Ecoart viz environmental art is that which encompasses the human ambience, e.g., landscape or its components. Bioart call be defined as the art whose material ("clay") is a living body, living matter or communication of organisms (which may include, e.g., genetic engineering). It is concluded that the acceptance of biosemiotic view has implications for a large area of ecological philosophy. (shrink)

We first summarize and comment upon a 'calculus of intrinsic preferability' which we have presented in detail elsewhere. 1 Then we set forth 'the problem of supererogation' - a problem which, according to some, has presented difficulties for deontic logic. And, finally, we propose a moral or deontic interpretation of the calculus of intrinsic preferability which, we believe, enables us to solve the problem of supererogation.

We provide a brief overview of the shift toward the intrinsic view of brain activity, describing in particular the structural and functional connectivity patterns of the “Default mode network”. We then consider the Default mode network in a specifically cognitive setting and ask what changes the focus on the Default mode network and other sorts of intrinsic activity require from models put forward by cognitive neuroscientists.

A‐theorists of time postulate a deep distinction between the present, past and future. Settling on an appropriate logic for such a view is no easy matter. This Philosophy Compass article describes one of the most vexing formal problems facing A‐theorists. It is commonly thought that A‐theories can only be formally expressed in a tense logic: a logic with operators like P and F . And it seems natural to think that we live in a world where objects come to exist (...) and cease to exist as time passes. Indeed, this is typically a key component of the most prominent kind of A‐theory, presentism. But the temporary existence assumption cannot be upheld in any tense logic with a standard quantification theory. I will explain the problem and outline the philosophical and logical considerations that generate it. I will then consider two possible solutions to the problem – one that targets our logic of quantification and one that targets our assumptions about change. I survey the costs of each solution.

One premise in David Lewis’s well-known argument from temporary intrinsic properties in favor of temporal parts is the intuition that material objects exemplify such properties simpliciter, that is, without qualification. The argument has spawned a large critical literature, with commentators questioning the simpliciter premise’s motivation, content, dialectical force, and status as an intuition. The present essay has two chief goals: to provide a novel framework for clarifying Lewis’s simpliciter premise and to explain how the resulting clarification upends a wide (...) range of attempts in the literature to evade his conclusion. Central to both goals is the observation that exemplification simpliciter best comports with our most fundamental notion of property exemplification, a notion that applies equally well to material and atemporal abstract objects.

T:HE CONCEPT OF human nature as the intrinsic and wdical source of characteristic human a;ctivity has great mportanoe for natural law ethics. But olosely allied to the concept of human nature is the possibility of there being tmnsient natures in humans, and this rpossirbility has implications for human life at its (...) outer edges. What transient natures are wiill he discussed 1in detail below. Let us,say for now that they are the life principles of entities transition from one state of being to another. These forms enjoy only a temporary existence before they disappear and are replaced by other emerging forms.1 When applied to the outer limits of human existence, such transient natures offer useful insights for addressing the difficult problems of when personhood begins and when death occurs. Thomistic philosophy defines a human person a;s a combination of mrutte1· and,form, more oommorrly referred to as a unity of hody and soul.2 Relativie to the beginning of Jife and the 1 Such natures are discussed in William A.

This essay was originally presented at an international conference held at the Joseph and Rose Kenned,y Institute of Ethies of Georgetown UniYersity, October 13-16, 1986.

Is the newly-fortiilized zygote capable of :receiving and sustaining the rational soul as its,substantirul form? Or must the genetic materials be informed by one or more transient natures before they achieve ithe internal unity and stability necessary :for personhood? At the end of life, the person dies when the soul leaves the body. Does personail death coincide with the death of the human organism as a whole? Or can the destruction of only an essential part of the body, e.g. tihe cerebral cortex, cause personal death by damaging the body so severely that it is simply incapable of supporting a :rational soul, even though the rest of the body remains intact and spontaneously alive? If so, is the remaining organism informed by a succession of transient substantiail forms that maintain its existence but at ever lower levels of life as it gradually declines toward total death? In examining these questions posed by the possibility of transient natures, my point of departure will be an analysis of transient natures themselves. Recently, William A. Wallace, O.P., has 'begun to eX!plore the philosophical meaning and implications of transient natures for issues such as these.a His findings will he summarized here. The insights gathered from the exploration of transient natures will next he applied to the questions of when personhood begins and when death occurs.

I discuss Eckhart’s and Aquinas’ conception of human-divine union with reference to what I call the problem of intrinsic goods, a problem concerning how to reconcile the pursuit of actions which are prima facie sought for their own sake (e.g. pursuing justice for the marginalized, listening to a work of music) with the pursuit of God as the ultimate end of every action. I introduce the problem with the help of Germain Grisez’s critique of Aquinas’ account of (...) union with God, and I suggest that Eckhart’s alternative conception of union may be understood as an attempt to resolve (or dissolve) the problem.

Intrinsic properties are those which cannot be had or lacked in virtue of other things. Being a square is intrinsic, in this sense, whereas being next to a square is not. But what, exactly, counts as an “other thing” in this context? As it turns out, this is a surprisingly difficult question. I provide a critical assessment of three existing proposals (in terms of identity, mereology, and ontology), before developing my own, alternative account. Along the way, we highlight ways in (...) which this project intersects with other philosophical issues, including debates over the nature of existence, the essentiality of origins, and the truth of priority monism.
