A person is biased toward the future when she prefers, other things being equal, bad events to be in her past rather than her future or good ones to be in her future rather than her past. In this paper, I explain why both critics and defenders of future bias have failed to consider the best version of the view. I distinguish external time from personal time, and show that future bias is best construed in terms of the latter. This (...) understanding of future bias avoids several standard objections. I then consider a new justification of future bias which is consistent with that construal. My discussion points to a new position regarding the basic relation that grounds rational egoistic concern over time, according to which that relation is asymmetric between person-stages. I also explain how this way of justifying future bias would resolve the apparent tension between the future bias we display in our own case and our relative indifference toward the timing of the good and bad things that happen to other people.

This book argues that a plausible account of emergence requires replacing the traditional assumption that what primarily exists are particular entities with generic processes. Traversing contemporary physics and issues of identity over time, it then proceeds to develop a metaphysical taxonomy of emergent entities and of the character of human life.

ABSTRACT One simple but relatively neglected solution to the notorious coincidence puzzle of the statue and the piece of clay claims that the property of being a statue is a phase sortal property that the piece of clay instantiates temporarily. I defend this view against some standard objections, by reinforcing it with a novel counterpart-theoretic account of identity under a sortal. This proposal does not require colocation, four-dimensionalism, eliminativism, deflationism, or unorthodox theses about classical identity.

By considering situations from the paradox of the twins in relativity, it is shown that time passes at different rates along different world lines, answering some well-known objections. The best explanation for the different rates is that time indeed passes. If time along a world line is something with a rate, and a variable rate, then it is difficult to see it as merely a unique, invariant, monotonic parameter without any further explanation of what it is. Although it could, conceivably, (...) be explained by the flow of something, it is better explained by the passing of a point present, which faces the problem that there is no absolute simultaneity in special relativity so that the present for an object is confined to just that object. This raises problems about presentism, eternalism, simultaneity, and special relativity. These issues are addressed first by giving accounts of presentism and eternalism and then an account of existence and times for objects relative to world lines. Finally, an analogy between a world of relativistic objects and Leibniz’s ontology of monads. (shrink)

My aim in what follows is to expound and (if possible) resolve two problems in Spinoza’s theory of mind. The first problem is how Spinoza can accept a key premise in Descartes’s argument for dualism—that thought and extension are separately conceivable, “one without the help of the other”—without accepting Descartes’s conclusion that no substance is both thinking and extended. Resolving this problem will require us to consider a crucial ambiguity in the notion of conceiving one thing without another, the credentials (...) of Descartes’s principle that each substance has a principal attribute, and the prospect of neutral monism as a theory of the mind. The second problem is how Spinoza can maintain that each mental event is identical with some physical event (and conversely) while denying that there is ever any causal interaction between mental and physical events. If one mental event causes another and the first is identical with some physical event, must that physical event not cause the mental event? Resolving this problem will require looking into the reach of opacity in Spinoza’s philosophy and considering whether there are ever any legitimate exceptions to Leibniz’s Law. (shrink)

Several have denied that there is, specifically, a criterion of identity for persons and some deny that there are, for any kind, diachronic criteria of identity. I argue, however, that there are no criteria of identity, either synchronic or diachronic, for any kind whatsoever. I begin by elaborating the notion of a criterion of identity in order to clarify what exactly is being denied when I maintain there are none. I examine the motivation of those who qualify in some way (...) the general claim that there are synchronic and diachronic criteria of identity for every kind, then present my direct and categorical argument against such criteria. I next evaluate the objections of those who argue that rejecting criteria of identity has untenable results. These objections are ineffective, each based on the incorrect assumption that if there is no criterion of identity for a kind, the identity of an instance of that kind is independent of its qualities. I conclude by considering some of the upshots of rejecting criteria of identity and the insight doing so provides into things in general and the limits of ontological inquiry. (shrink)

According to the Psychological-Continuity Account of What Matters, you are justified in having special concern for the well-being of a person at a future time if and only if that person will be psychologically continuous with you as you are now. On some versions of the account, the psychological continuity is required be temporally ordered, whereas, on other versions, it is allowed to be temporally unordered. In this paper, I argue that the account is implausible if the psychological continuity is (...) allowed to be temporally unordered. I also argue that, if the psychological continuity is required to be temporally ordered, it cannot plausibly be purely psychological (in the sense that the psychological continuity is not required to be caused through spatio-temporal continuity of a brain). The upshot is that no plausible version of the Psychological-Continuity Account of What Matters is purely psychological. So psychological continuity is not what matters in survival. (shrink)

We say that each social group is identical to its members. The group just is them; they just are the group. This view of groups as pluralities has tended to be swiftly rejected by social metaphysicians, if considered at all, mainly on the basis of two objections. First, it is argued that groups can change in membership, while pluralities cannot. Second, it is argued that different groups can have exactly the same members, while different pluralities cannot. We rebut these objections, (...) and argue that our plural view is superior to alternative reductive proposals which would identify social groups with the sets or fusions of their members. Finally we deal with some further potential challenges for the view of groups as pluralities. Thus we aim to establish it as a serious contender in the metaphysics of groups. (shrink)

There is much to be said for a diachronic or interpersonal individuation of singular modes of presentation (MOPs) in terms of a criterion of epistemic transparency between thought tokens. This way of individuating MOPs has been discussed recently within the mental files framework, though the issues discussed here arise for all theories that individuate MOPs in terms of relations among tokens. All such theories face objections concerning apparent failures of the transitivity of the ‘same MOP’ relation. For mental files, these (...) transitivity failures most obviously occur because mental files can merge or undergo fission. In this paper I argue that this problem is easily resolved once mental files are properly construed as continuants, whose metaphysics is analogous to that of persons or physical objects. All continuants can undergo fission or fusion, leading to similar transitivity problems, but there are well-established theories of persistence that accommodate this. I suggest that, in particular, the stage theory best suits the purposes of a continuant theory of MOPs. (shrink)

Given reductionism about people, personal persistence must fundamentally consist in some kind of impersonal continuity relation. Typically, these continuity relations can hold from one to many. And, if they can, the analysis of personal persistence must include a non-branching clause to avoid non-transitive identities or multiple occupancy. It is far from obvious, however, what form this clause should take. This paper argues that previous accounts are inadequate and develops a new proposal.

Although it is very often taken for granted that there is something fundamental, the literature appears to have developed with little to no careful consideration of what exactly it is that the fundamentalia are supposed to do. If we are to have a good reason to believe that there is something fundamental, we need not only to know what exactly it is that the fundamentalia are invoked for, but why it is that nothing else is available for the task to (...) hand. A good argument in defense of fundamentality, then, will contain an assumption that stipulates an explanatory target; along with a second, crucial, assumption that tells us that no dependent entity is available to do the work that needs to be done. In this paper, I explore both of these assumptions. (shrink)

In this paper we present a new metaphysical theory of material objects. On our theory, objects are bundles of property instances, where those properties give the nature or essence of that object. We call the theory essential bundle theory. Property possession is not analysed as bundle-membership, as in traditional bundle theories, since accidental properties are not included in the object’s bundle. We have a different story to tell about accidental property possession. This move reaps many benefits. Essential bundle theory delivers (...) a simple theory of the essential properties of material objects; an explanation of how object coincidence can arise; an actual-world ground for modal differences between coincident objects; a simple story about intrinsic properties; and a plausible account of certain ubiquitous cases of causal overdetermination.

Many people believe that for someone to now be responsible for some past action, the agent of that action and the responsible agent now must be one and the same person. In other words, many people that moral responsibility presupposes numerical personal identity. In this paper, I show why this platitude is false. I then suggest an account of what actual metaphysical relationship moral responsibility presupposes instead.

The central claim of this paper is that the Aristotelian metaphysics of objects is incompatible with physicalism. This includes the contemporary variant of Aristotelianism I call ‘sortalism’. The core reason is that an object’s identity as an instance of a (natural) kind, as well as its consequent persistence conditions, is neither physically fundamental nor determined by what is physically fundamental. The argument for the latter appeals to what is commonly known as ‘the grounding problem’; in particular I argue that the (...) physicalist has no solution, and this requires that the physicalist jettison the traditional concept of objects having kind-specific identity and persistence conditions. (shrink)

Derek Parfit’s argument against the platitude that identity is what matters in survival does not work given his intended reading of the platitude, namely, that what matters in survival to some future time is being identical with someone who is alive at that time. I develop Parfit’s argument so that it works against the platitude on this intended reading.

I address two related questions: first, what is the best theory of how objects have de re modal properties? Second, what is the best defence of essentialism given the variability of our modal intuitions? I critically discuss several theories of how objects have their de re modal properties and address the most threatening antiessentialist objection to essentialism: the variability of our modal intuitions. Drawing on linguistic treatments of vagueness and ambiguity, I show how essentialists can accommodate the variability of modal (...) intuitions while holding that objects have their modal properties independently of contexts.

I try to lay bare some of the conceptual space in which one may be a Social Trinitarian. I organize the paper around answers to five questions. These are: (1) How do the three Persons of the Trinity relate to the Godhead? (2) How many divine beings or gods are there? (3) How many distinct centers of consciousness are there in the Godhead? (4) How many omnicompetent beings are there? (5) How are the Persons of the Trinity individuated? I try (...) to make clear costs and benefits of various answers to these questions. (shrink)

This thesis explores the possibility of composite consciousness: phenomenally conscious states belonging to a composite being in virtue of the consciousness of, and relations among, its parts. We have no trouble accepting that a composite being has physical properties entirely in virtue of the physical properties of, and relations among, its parts. But a long­standing intuition holds that consciousness is different: my consciousness cannot be understood as a complex of interacting component consciousnesses belonging to parts of me. I ask why: (...) what is it about consciousness that makes us think it so different from matter? And should we accept this apparent difference? (shrink)

I argue that there are good reasons to assume that Quine’s theory of reference and ontology is incompatible with reductive statements – such as ‘Heat is molecular motion’ or ‘Rabbits are conglomerations of cells’. Apparently, reductive statements imply certain intertheoretical identities, yet Quine’s theory of reference and ontology seems incompatible with intertheoretical identities. I argued that treating, for the sake of reconciliation, reductive statements along the lines of Quine’s theory of an ontological reduction (which does not imply intertheoretical identity) fails. (...) Then I discussed two alternative strategies on behalf of Quine to handle reductive statements: the Holistic Strategy (which appeals to Quine’s notion of an all-encompassing background theory) and the Individuative Strategy (which draws on Quine’s notion of an apparatus of individuation). I argue that the Individuative Strategy promises to succeed. However, the Individuative Strategy obliges to revising Quine’s theory of an ontological reduction – a revision that, as I argue, can and should be implemented. (shrink)

Critics of luck egalitarianism have claimed that, far from providing a justification for the public insurance functions of a welfare state as its proponents claim, the view objectionably abandons those who are deemed responsible for their dire straits. This article considers seven arguments that can be made in response to this ‘abandonment objection’. Four of these arguments are found wanting, with a recurrent problem being their reliance on a dubious sufficientarian or quasi-sufficientarian commitment to provide a threshold of goods unconditionally. (...) Three arguments succeed, showing that luck egalitarians have good reasons for assisting ‘negligent victims’ on account of changes that may occur in an individual between the time of their choice and their subsequent disadvantage, bad option luck, and doubts about free will and responsibility. Luck egalitarianism is therefore shown to offer strong support for public insurance. (shrink)

The writings of Joseph Henry Woodger (1894–1981) are often taken to exemplify everything that was wrongheaded, misguided, and just plain wrong with early twentieth-century philosophy of biology. Over the years, commentators have said of Woodger: (a) that he was a fervent logical empiricist who tried to impose the explanatory gold standards of physics onto biology, (b) that his philosophical work was completely disconnected from biological science, (c) that he possessed no scientific or philosophical credentials, and (d) that his work was (...) disparaged – if not altogether ignored – by the biologists and philosophers of his era. In this paper, we provide the first systematic examination of Woodger’s oeuvre, and use it to demonstrate that the four preceding claims are false. We argue that Woodger’s ideas have exerted an important influence on biology and philosophy, and submit that the current consensus on his legacy stems from a highly selective reading of his works. By rehabilitating Woodger, we hope to show that there is no good reason to continue to disregard the numerous contributions to the philosophy of biology produced in the decades prior to the professionalization of the discipline.

Why is there something rather than nothing? Apparently many people regard that question as a challenge to naturalism because they think it’s too fundamental or too sweeping for natural science to answer, even in principle. I argue, on the contrary, that the question has a simple and adequate naturalistic answer: ‘Because there are penguins.’ I then diagnose various confusions underlying the suspicion that the question can’t have such an answer and, more generally, that the question, or else some variant of (...) it, can’t have a naturalistic answer at all.

Some have objected to the laboratory cloning of human preembryos on the grounds that the procedure would violate the dignity of and respect owed to human preembryos. Others have argued that human cloning ought be permitted if it will predictably benefit, or at least not burden, individuals who are, unlike the human preembryo, clearly entitled to our respect and concern. Taking this latter position, the legal theorist John A. Robertson has argued that, since cloning does not harm anyone who is (...) clearly entitled to our respect and concern, it should be permitted. In particular, the offspring of cloning, he argues, cannot be genuinely harmed by cloning, since they owe their very existence to the cloning procedure. In this paper, I argue that cloning coupled with its related procedures does in fact place the flesh and blood human offspring of cloning at risk of genuine harm. I thus provide a basis for questioning the moral permissibility of cloning and its related technologies without implying that the human preembryo has dignity or is owed respect. (shrink)

Abstract Of the many ways in which identity is constructed and performed online, few are as strongly ‘anchored’ to existing offline relationships as in online social networks like Facebook and Myspace. These networks utilise profiles that extend our practical, psychological and even corporeal identity in ways that give them considerable phenomenal presence in the lives of spatially distant people. This raises interesting questions about the persistence of identity when these online profiles survive the deaths of the users behind them, via (...) the practice of ‘memorialising’ social network profile pages. I situate these practices within a phenomenology of grief that accounts for the ways in which the dead can persist as moral patients, and show how online survival in this case illuminates an important difference between persons and selves within contemporary philosophy of personal identity. Ultimately, the online persistence of the dead helps bring into view a deep ontological contradiction implicit in our dealings with death: the dead both live on as objects of duty and yet completely cease to exist.

Leibniz’s Law (or as it sometimes called, ‘the Indiscerniblity of Identicals’) is a widely accepted principle governing the notion of numerical identity. The principle states that if a is identical to b, then any property had by a is also had by b. Leibniz’s Law may seem like a trivial principle, but its apparent consequences are far from trivial. The law has been utilised in a wide range of arguments in metaphysics, many leading to substantive and controversial conclusions. This article (...) discusses the applications of Leibniz’s Law to arguments in metaphysics. It begins by presenting a variety of central arguments in metaphysics which appeal to the law. The article then proceeds to discuss a range of strategies that can be drawn upon in resisting an argument by Leibniz’s Law. These strategies divide into three categories: (i) denying Leibniz’s Law; (ii) denying that the argument in question involves a genuine application of the law; and (iii) denying that the argument’s premises are true. Strategies falling under each of these three categories are discussed in turn. (shrink)

This paper explores how the diagnosis of mental disorder may affect the diagnosed subject’s self-concept by supplying an account that emphasizes the influence of autobiographical and social narratives on self-understanding. It focuses primarily on the diagnoses made according to the criteria provided by the Diagnostic Statistical Manual of Mental Disorders (DSM), and suggests that the DSM diagnosis may function as a source of narrative that affects the subject’s self-concept. Engaging in this analysis by appealing to autobiographies and memoirs written by (...) people diagnosed with mental disorder, the paper concludes that a DSM diagnosis is a double-edged sword for self- concept. On the one hand, it sets the subject’s experience in an established classificatory system which can facilitate self-understanding by providing insight into subject’s condition and guiding her personal growth, as well as treatment and recovery. In this sense, the DSM diagnosis may have positive repercussions on self-development. On the other hand, however, given the DSM’s symptom-based approach and its adoption of the Biomedical Disease model, a diagnosis may force the subject to make sense of her condition divorced from other elements in her life that may be affecting her mental- health. It may lead her frame her experience only as an irreversible imbalance. This form of self-understanding may set limits on the subject’s hopes of recovery and may create impediments to her flourishing. (shrink)

Much of the debate about identity in recent decades has been about personal identity, and specifically about personal identity over time, but identity generally, and the identity of things of other kinds, have also attracted attention. Various interrelated problems have been at the centre of discussion, but it is fair to say that recent work has focussed particularly on the following areas: the notion of a criterion of identity; the correct analysis of identity over time, and, in particular, the disagreement (...) between advocates of perdurance and advocates of endurance as analyses of identity over time; the notion of identity across possible worlds and the question of its relevance to the correct analysis of de re modal discourse; the notion of contingent identity; the question of whether the identity relation is, or is similar to, the composition relation; and the notion of vague identity. A radical position, advocated by Peter Geach, is that these debates, as usually conducted, are void for lack of a subject matter: the notion of absolute identity they presuppose has no application; there is only relative identity. Another increasingly popular view is the one advocated by Lewis: although the debates make sense they cannot genuinely be debates about identity, since there are no philosophical problems about identity. Identity is an utterly unproblematic notion. What there are, are genuine problems which can be stated using the language of identity. But since these can be restated without the language of identity they are not problems about identity. (For example, it is a puzzle, an aspect of the so-called “problem of personal identity”, whether the same person can have different bodies at different times. But this is just the puzzle whether a person can have different bodies at different times. So since it can be stated without the language of personal “identity”, it is not a problem about identity, but about personhood.) This article provides an overview of the topics indicated above, some assessment of the debates and suggestions for further reading. (shrink)

I describe an account of ontological categories which does justice to the facts that not all categories are ontological categories and that ontological categories can stand in containment relations. The account sorts objects into different categories in the same way in which grammar sorts expressions . It then identifies the ontological categories with those which play a certain role in the systematization of collections of categories. The paper concludes by noting that on my account what ontological categories there are is (...) partially interest-relative, and that furthermore no object can belong essentially to its ontological category.

If an object has a property essentially, it has that property in every possible world according to which it exists.2 If an object has a property accidentally, it does not have that property in every possible world according to which it exists. Claims about an object’s essential or accidental properties are de re modal claims, and essential and accidental properties are de re modal properties. Take an object’s modal profile to specify its essential properties and the range of its accidental (...) properties. Note that “world” as I am using it is a term of art: a modal realist believes that there are many concrete worlds, while the actualist believes in only one concrete world, the actual world. The ersatzist is an actualist who takes nonactual possible worlds and their contents to be abstracta. Essentialism is the view that objects have properties essentially, but one should distinguish deep essentialism from shallow essentialism. Deep essentialists take the (nontrivial) essential properties of an object to determine its nature— such properties give sense to the idea that an object has a unique and distinctive character, and make it the case that an object has to be a certain way in order for it to be at all.3 As Stephen Yablo (1987, 297) describes it, the essence of a thing is “an assortment of properties in virtue of which it is the entity in question,” as well as “a measure of what is required for it to be that thing.” Intuitively, on the deep essentialist picture, an ordinary object has essential properties, and it must have its essential properties in order for it to exist. On this view, objects’ essential properties are absolute, i.e., are not determined by contexts of describing (or thinking, etc.) about the object, and truths about such properties are absolute truths.4 Shallow essentialists oppose deep essentialists: they reject the view that objects can be said to have essential properties independently of contexts of description or evaluation, and so substitute context-dependent truths for the deep essentialist’s context-independent ones..

This paper discusses how alternative concepts of personhood affect the definition of death. I argue that parties in the debate over the definition of death have employed different concepts of personhood, and thus have been talking past each other by proposing definitions of death for different kinds of things. In particular, I show how critics of the consciousness-related, neurological formation of death have relied on concepts of personhood that would be rejected by proponents of that formulation. These critics rest on (...) treating persons as qualitative specifications of human organisms or as identical to human organisms. Since advocates of the consciousness-related, neurological formulation of death are not committed to either of these views of personhood, these critics commit the fallacy of attacking a straw man. I then clarify the substantive concept of personhood that may be invoked in the consciousness-related, neurological formulation of death, and argue that, on this view and contra Bernat, Culver, and Gert, persons have always been the kind of thing that can literally die. I conclude by suggesting that the discussion of defining death needs to focus on which approach to personhood makes the most sense metaphysically and morally. (shrink)

The rare condition known as dicephalus occurs when (prior to implantation) a zygote fails to divide completely, resulting in twins who are conjoined below the neck. Human dicephalic twins look like a two-headed person, with each brain supporting a distinct mental life. Jeff McMahan has recently argued that, because they instance two of us but only one animal, dicephalic twins provide a counterexample to the animalist's claim that each of us is identical with a human animal. To the contrary, I (...) argue that in cases of dicephalus it is obvious neither that there is one animal nor that there are two of us. Consequently, the animalist criterion does not straightforwardly apply to cases of dicephalus. I defend an account of dicephalus that is both sensitive to the complexity of twinning phenomena and not inconsistent with animalism. In my view, dicephalic twins are a borderline case of the concept HUMAN ANIMAL. I conclude with some speculative remarks concerning the normative import (if any) of my claim that dicephalic twins are a borderline case. (shrink)

Olson (1997a) tries to refute the Psychological Approach to personal identity with his Fetus Argument, and Mackie (1999) aims to do the same with the Death Argument. With the help of a suggestion made by Baker (1999), the following discussion shows that these arguments fail. In the process of defending the Psychological Approach, it is made clear exactly what one is and is not committed to as a proponent of the theory.

David lewis has argued that--Despite the 'fission' cases--One may consistently hold both that what matters in survival is "mental continuity and connectedness" and that what matters in survival is identity.

In this paper, The author questions their objections, And then argues that, Even though lewis's theory has many (...) virtues, No sufficiently knowledgeable person can be justified in accepting it (here and now) as an adequate theory of persons.

Many of the concepts analysed by philosophers have their origin in ordinary – or at least extra-philosophical – language. Perception, knowledge, causation, and mind are examples. But the concept of substance is a philosophical term of art. Its uses in ordinary language tend to derive, often in a rather distorted way, from the philosophical senses. There is an ordinary concept in play when philosophers discuss “substance”, and this, as we shall see, is the concept of object, or thing when this (...) is contrasted with properties or events. But such “individual substances” are never termed “substances” outside philosophy. -/- There exist two rather different ways of characterising the philosophical concept of substance. The first is the more generic. The philosophical term “substance” comes from an early Latin translation of the Greek ousia. Ousia is a noun derived from the verb “einai” (to be) and is naturally translated “being”. According to the generic sense, substances are those things that best merit the title “beings”. This is usually interpreted to mean those things that are the foundational or fundamental entities of a given philosophical system. Thus, for an atomist, atoms are the substances, for they are the basic things from which everything is constructed. In David Hume’s system, impressions and ideas are the substances, for the same reason. In a slightly different way, Forms are Plato’s substances, for everything derives its existence from Forms. -/- The second use of the concept is more specific. According to this usage, substances are a particular kind of entity, and some philosophical theories acknowledge them and others do not. This conception of substance derives from the intuitive notion of individual thing or object, which contrasts mainly with properties and events. According to this usage, it is a live issue whether the fundamental entities are substances or something else, such as events, or properties located at space-times. The issue is how we are to understand the notion of an object, and whether, in the light of the correct understanding, it remains a basic notion, or one that must be characterised in more fundamental terms. Whether, for example, an object can be thought of as nothing more than a bundle of properties, or a series of events. -/- The reason “substance” has acquired these two usages is that the work that introduced the term to philosophy, Aristotle’s Categories, claims that the things that most merit the title “beings” (substances in the generic sense) are individual objects as opposed to properties or events (substances in the specific sense).

Sortal concepts are at the center of certain logical discussions and have played a significant role in solutions to particular problems in philosophy. Apart from logic and philosophy, the study of sortal concepts has found its place in specific fields of psychology, such as the theory of infant cognitive development and the theory of human perception. In this monograph, different formal logics for sortal concepts and sortal-related logical notions are characterized. Most of these logics are intensional in nature and possess, (...) in addition, a bidimensional character. That is, they simultaneously represent two different logical dimensions. In most cases, the dimensions are those of time and natural necessity, and, in other cases, those of time and epistemic necessity. Another feature of the logics in question concerns second-order quantification over sortal concepts, a logical notion that is also represented in the logics. Some of the logics adopt a constant domain interpretation, others a varying domain interpretation of such quantification. Two of the above bidimensional logics are philosophically grounded on predication sortalism, that is, on the philosophical view that predication necessarily requires sortal concepts. Another bidimensional logic constitutes a logic for complex sortal predicates. These three sorts of logics are among the important novelties of this work since logics with similar features have not been developed up to now, and they might be instrumental for the solution of philosophically significant problems regarding sortal predicates. The book assumes a modern variant of conceptualism as a philosophical background. For this reason, the approach to sortal predicates is in terms of sortal concepts. Concepts, in general, are here understood as intersubjective realizable cognitive capacities. The proper features of sortal concepts are determined by an analysis of the main features of sortal predicates. Posterior to this analysis, the sortal-related logical notions represented in the above logics are discussed. There is also a discussion on the extent to which the set-theoretic formal semantic systems of the book capture different aspects of the conceptualist approach to sortals. These different semantic frameworks are also related to realist and nominalist approaches to sortal predicates, and possible modifications to them are considered that might represent those alternative approaches.

This paper defends a hylomorphic version of animalism according to which human persons survive as immaterial, bodiless animals after death. According to the hylomorphism under consideration, human persons have souls that survive death, and according to the animalism under consideration, human persons are necessarily animals. One might think this implies that human persons don't survive their deaths since if they were to survive their deaths, they would be immaterial animals after death, but necessarily animals are material. This paper shows that (...) the hylomorphic animalist can overcome this problem in a way that respects the intuition that animals are material. In addition, the paper defends the hylomorphic animalist survivalist from the objection that her view introduces an insoluble mereological puzzle. (shrink)

I argue for three central theses: ‘intuition’ is ambiguous, in material object metaphysics ‘intuition’ refers to pre-theoretical beliefs, and these pre-theoretical beliefs are generated by an innate physical reasoning system. I begin by outlining the relevant background discussions on the nature of intuitions and their role in philosophy to motivate the need for a more careful investigation of the meaning of ‘intuition’ and the role of intuitions in specific sub-disciplines of philosophy. In chapters one and two I argue that ‘intuition’ (...) is ambiguous between an inflationary and deflationary sense. In the inflationary sense, ‘intuition’ refers to a priori intellectual seemings with a special phenomenology, conceptual etiology, and modal content. In the deflationary sense, ‘intuition’ refers to beliefs or inclinations to believe. In chapter three I specifically examine the use of intuitions in material object metaphysics and conclude that in this sub-community ‘intuition’ is used in the deflationary sense to refer to pre-theoretical beliefs. Drawing from research on infant cognition, in the final chapter I argue that intuitions regarding material object metaphysics are those judgments that arise from an innate physical reasoning system. Based on this empirical observation, I argue that metaphysicians ought to give preference to abstract intuitions over intuitions regarding concrete cases because these abstract intuitions reflect the innate structure of our physical reasoning mechanisms.

This paper analyzes the transformation from the human zygote to the implanted embryo under the prism of substantial change. After a brief introduction, it vindicates the Aristotelian ideas of substance and accident, and those of substantial and accidental change. It then claims that the transformation from the multicelled zygote to the implanted embryo amounts to a substantial change. Pushing further, it contends that this substantial change cannot be explained following patterns of genetic reductionism, emergence, and self-organization, and proposes Gustavo Bueno’s (...) idea of anamorphosis as a means to encapsulate criticism against such positions.

Complex systems are dynamic and may show high levels of variability in both space and time. It is often difficult to decide on what constitutes a given complex system, i.e., where system boundaries should be set, and what amounts to substantial change within the system. We discuss two central themes: the nature of system definitions and their ability to cope with change, and the importance of system definitions for the mental metamodels that we use to describe and order ideas about (...) system change. Systems can only be considered as single study units if they retain their identity. Previous system definitions have largely ignored the need for both spatial and temporal continuity as essential attributes of identity. After considering the philosophical issues surrounding identity and system definitions, we examine their application to modeling studies. We outline a set of five alternative metamodels that capture a range of the basic dynamics of complex systems. Although Holling’s adaptive cycle is a compelling and widely applicable metamodel that fits many complex systems, there are systems that do not necessarily follow the adaptive cycle. We propose that more careful consideration of system definitions and alternative metamodels for complex systems will lead to greater conceptual clarity in the field and, ultimately, to more rigorous research.
