Like most theories in first order metaphysics, theories of persistence generally aim at metaphysically necessary truth. Consequently, those that accept proper temporal parts of material entities are maximally competitive only when they accord with the full range of metaphysically possible temporal mereological structures. Consider, for example, a structure in which every element is a proper temporal part of some others. The present essay argues that temporal junk plausibly is possible and that perdurantism, the thesis that material entities persist by having (...) distinct proper temporal parts at distinct times, does not accord with it. The essay then outlines a novel four-dimensionalist theory of persistence that accommodates junk. On this theory, material entities persist not in virtue of possessing proper temporal parts, but rather in virtue of being grounded by certain pluralities of fundamental property instances over their careers, and by sub-pluralities thereof over corresponding sub-intervals of their careers. Accordingly, this way of persisting is dubbed ‘plurdurance’. (shrink)

An object is T-gunky just in case all its parts (i) have proper parts and (ii) are of non-zero measure in every spatial dimension. I show that a recent argument due to Hud Hudson—though not intended as a threat to gunk—bears on the possibility of T-gunky material objects in non-gunky space. I then show that the friend of T-gunk can circumvent Hudson’s argument without abandoning pointy space or standard mereology. What is needed is a novel conception of the relation of (...) exact occupation of pointy regions by T-gunky objects. With the new conception in hand, the friend of material T-gunk need not look to theories of gunky spacetime in order to reconcile the possibility of material gunk with mathematical physics. (shrink)

Tropes are particular features of concrete objects. Properties—the extensions of predicates—are primitive resemblance classes of tropes. Friends of tropes have been criticized for failing to answer three questions. First, are there fundamental items other than tropes? Second, what criteria determine whether some tropes are all and only the features of some one object? Third, can trope classes be formed adequately using only primitive resemblance? Trading on the spatiotemporal status of tropes, this essay offers new responses to each of these questions. (...) The novel thesis is that there is a sui generis property called ‘markedness’, whose tropes “mark” certain locations in an ontologically basic way. The spatiotemporal distribution of markedness tropes fixes the distribution of familiar characterizing tropes like mass and charge, and characterizing tropes are bundled by being co-contained in the location of a maximally connected markedness trope. This novel theory of trope bundling is defended by appeal to theoretical utility: it is ontologically parsimonious and solves outstanding problems involving co-location and resemblance class construction.

A modus tollens against zero-dimensional material objects is presented from the premises (i) that if there are zero-dimensional material objects then there are bare particulars, and (ii) that there are no bare particulars. The argument for the first premise proceeds by elimination. First, bare particular theory and bundle theory are motivated as the most appealing theories of property exemplification. It is then argued that the bundle theorist’s Ockhamism ought to lead her to reject spatiotemporally located zero-dimensional property instances. Finally, it (...) is argued that since she must accept such instances if she accepts zero-dimensional material object bundles, she ought to avoid the latter. This leaves bare particular theory as the default view of zero-dimensional material objects. The argument for the second premise invokes the thesis that the exemplification of at least one sparse property is a prerequisite for the existence of any particular. It is argued from Humean considerations that bare particulars fail this prerequisite. (shrink)

Fundamental concrete particulars are needed to explain facts about non-fundamental concrete particulars. However, the former can only play this explanatory role if they are properly discernible from the latter. Extant theories of how to discern fundamental concreta primarily concern mereological structure. Those according to which fundamental concreta can bear, but not be, proper parts are motivated by the possibilities that all concreta bear proper parts and that some properties of wholes are not fixed by the properties of their proper parts. (...) In response, theorists who hold that the fundamental concrete particulars can be proper parts may appeal to the possibility that every concrete particular is a proper part—that there is no mereologically maximal whole world, as well as to the intuition that fundamental concreta are qualitatively homogeneous “blocks” from which non-fundamental concreta are built. After motivating the plausibility of gunk and junk, the present essay proposes a constraint on fundamental concrete particulars based on topology instead of mereology: the fundamental concrete particulars must be appropriately connected. This constraint has the unique advantage of consistency with each of gunk, emergence, junk, and the building block intuition. (shrink)

According to the cluster of theories in the metaphysics of properties known as ‘trope’ theories, properties are collections of particular qualitative instances. Though increasingly influential, the cluster is sufficiently diverse for there to be little agreement as to the prospects of its members. The present essay articulates and defends a conception of tropes as primitively qualitatively complex, somewhat in the vein of Quinean nominalist objects. After clarifying the relationships among tropes, properties, property exemplification, and property conferral, the essay discusses the (...) benefits of this new ‘ostrich’ trope theory. Specifically, the theory explains better than prior trope theories both the spatiotemporal status of tropes and the capacity tropes have to confer properties onto objects. Moreover, the theory is immune to many of the concerns that threaten more orthodox trope ontologies. (shrink)

According to the identity version of spacetime supersubstantivalism, material objects are numerically identical to spacetime regions. While the view has been commended for its parsimony and concordance with physics, it has not properly been assessed in light of the metaphysics of properties. The present essay fills this void by discerning several subspecies of identity supersubstantivalism, corresponding to various property ontologies. Finding them all wanting, the essay develops and defends a novel brand of supersubstantivalism based on the trope ontology. On this (...) view, here dubbed ‘supertropestantivalism’, regions are pluralities of geometrically and topologically alike tropes, some of which bundle together as material objects. The resulting picture is not itself an identity version of supersubstantivalism, but it retains the originally attractive features of the identity version while avoiding the shortcomings of competing ontologies.

We have compelling extra-philosophical reasons for caring about identity, parthood, and location. For example, we desire ceteris paribus that nothing every part of which is very near to our location be very near to the location of something dangerous, evil, or otherwise unpleasant. This essay argues that such considerations are relevant to certain first-order metaphysical debates, namely, the debates over immanent universals and tropes and endurantism and perdurantism, respectively. As a consequence, even the non-specialist has a reason to care about (...) the metaphysics of properties and persistence. (shrink)

Substance dualism is the view that there are two fundamentally different kinds of substances: physical and mental. By contrast, according to property dualism there is only one kind of substance (physical) but two fundamentally different kinds of properties: physical and mental. Property nominalism is the view that there are neither repeatable nor non-repeatable fundamentally predicable entities (i.e. neither universals nor tropes) and that things being a certain way or being related in a certain way must ultimately be accounted for in (...) terms of concrete particulars. In this paper, we consider a number of different kinds of property nominalism and argue that none of them sits well with property dualism. We pay special attention to the question of what it could mean for a property to count as mental given different nominalistic accounts of properties. Our conclusion is that property nominalism and property dualism are not a stable match. This is surprising, since property dualism has usually been understood as a thesis that is neutral about the nature of fundamental ontological categories and the relation between them. (shrink)

A mereological structure is junky if and only if each of its elements is a proper part of some other. The young literature on junk has focused on junky worlds and whether they are counterexamples to unrestricted composition. The present note defends the possibility of junky structures that are not worlds. This possibility complicates a recent attempt in the literature to render junk consistent with a weakened form of unrestricted composition. The upshot is that junky non-worlds threaten the weakened form (...) of unrestricted composition as much as junky worlds threaten the traditional version. (shrink)

According to the indiscernibility characterization of the distinction between particulars and universals, only and all the former have possible numerically distinct indiscernible intrinsic qualitative duplicates. It is argued here that both the sufficiency and the necessity directions are defective and that indiscernibility thus does not distinguish particularity. Against sufficiency: universals may lack intrinsic qualitative character and thus be trivially indiscernible from one another. Against necessity: pluralities of duplicate-less entities are at once duplicate-less and particular.

According to the broadly Aristotelian distinction between universals and particulars, all and only the former are capable of whole multiple location. The present essay defends this distinction against four putative counterexamples. The first two, extended simple material objects and enduring time-traveling self-meeters, putatively are wholly multiply locatable, but not universals. The second two, unique properties of point-sized entities and Platonic (i.e., not spatiotemporally located) universals, putatively are universals, but not wholly multiply locatable. The defensive strategy is to resist certain presuppositions (...) underlying the examples. (shrink)

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.

Thought: A Journal of Philosophy, EarlyView.

A context-shifting example involves a putatively non-ambiguous, non-elliptical, non-indexical declarative sentence, some distinct utterances of which differ in truth value despite sameness of place, time, surrounding objects, and other physical factors. Charles Travis has spawned a large literature by arguing that such examples undermine compositional truth-conditional semantics. After explaining how prior responses to Travis’s examples fail in the metaphysical details, the present essay develops a new approach that treats a wide range of subject terms as disguised indexicals sensitive to mereological (...) structure.

According to the traditional way of understanding debates in the metaphysics of persistence, perdurantists hold that persisting material objects have temporal proper parts while endurantists hold that they do not. Several theorists recently have suggested in opposition to this traditional picture that endurantism be understood as the thesis that the identity of a persisting object x is intrinsic to each of the times at which x is present. It is argued here that unless this non-traditional version of endurantism entails a (...) certain haecceitist element, it is subject to counterexample from the metaphysical possibility that two qualitatively identical material objects "pass through" one another during some portion of their respective careers. It is argued further that the suggested version of endurantism does not mix well with haecceitism and that consequently it is best resisted. (shrink)

The problem of many-over-one asks how it can be thatmanyproperties are ever instantiated byoneobject. A putative solution might, for example, claim that the properties are appropriately bundled, or somehow tied to a bare particular. In this essay, the author argues that, surprisingly, an extant candidate solution to this problem is at the same time an independently developed candidate solution to the mind-body problem. Specifically, what is argued here to be the best version of the relata-specific bundle theory—the thesis that each (...) instance of compresence has a special intrinsic nature in virtue of which it necessarily bundles its specific bundle-ees—is also a species of Russellian monism, labeled by David Chalmers as ‘constitutive Russellian panprotopsychism’. The upshot of this connection is significant for the metaphysics of the mind-body problem: a credible theory of property instantiation turns out to have a built-in account of how consciousness is grounded in certain (broadly) physical systems.

Tyler Burge has recently argued that quasi-memory-based psychological reductionist accounts of diachronic personal identity are deeply problematic. According to Burge, these accounts either fail to include appropriately de se elements or presuppose facts about diachronic personal identity—facts of the very kind that the accounts are supposed to explain. Neither of these objections is compelling. The first is based in confusion about the version of reductionism to which it putatively applies. The second loses its force when we recognize that reductionism is (...) a metaphysical thesis, not an epistemological one. (shrink)

All parts of mereologically ‘gunky’ entities have proper parts. All parts relevant to mereologically ‘junky’ entities *are* proper parts. This essay explores the application of gunk and junk beyond the standard category of material object. One such application yields what is here dubbed ‘deep’ gunk and junk: a material entity x all of whose intrinsic elements from any fundamental ontological category C either have proper parts from C that also are intrinsic elements of x, or are proper parts of entities (...) from C that also are intrinsic elements of x. In addition to being independently interesting, these mereological structures pose a challenge to the bare particular ontology of substance. For bare particulars standardly are assumed to be mereologically simple, yet a deep gunky or junky entity requires any associated bare particulars to be complex. The essay closes by examining the bare particular theorist’s prospects for answering this challenge. (shrink)

Zombies are unconscious objects with conscious physical micro-duplicates. If zombies are possible then physicalism is false. It has been argued that zombies are possible if conceivable for an agent with ideal rationality. At any rate, they are possible only if so conceivable. This essay uses a mereological constraint to highlight the fine-grained differences between actually conscious physical objects and certain of their actually consciousness-incapable proper parts. These mereological considerations form the basis of an argument by dilemma that zombies are inconceivable. (...) Either an arbitrary actually conscious object might have had simpler consciousness-capable parts than it in fact has, or not. The affirmative horn leads to a version of panpsychism that is inconsistent with the ideal conceivability of zombies. The negative horn rules out zombies as incoherent. The upshot is a new reason to deny the conceivability of zombies. (shrink)

“X-Firsters” hold that there is some normative feature that is fundamental to all others (and, often, that there’s some normative feature that is the “mark of the normative”: all other normative properties have it, and are normative in virtue of having it). This view is taken as a starting point in the debate about which X is “on first.” Little has been said about whether or why we should be X-Firsters, or what we should think about normativity if we aren’t (...) X-Firsters. Hence the chapter’s two main goals. First, to provide a simple argument that one shouldn’t be an X-Firster about the normative domain, which starts with the observation that analogous views have dubious merits in analogous domains. Second, to offer an alternative view—taking normativity to be a determinable explained in terms of its determinates—that offers an interesting way to think about the structure and unity of normativity.

Supporters of open borders sometimes argue that the state has no pro tanto right to restrict immigration, because such a right would also entail a right to exclude existing citizens for whatever reasons justify excluding immigrants. These arguments can be defeated by suggesting that people have a right to stay put. I present a new form of the exclusion argument against closed borders which escapes this “right to stay put” reply. I do this by describing a kind of exclusion that (...) has not been discussed in depth, which I call “territorial exclusion.” Territorial exclusion is the process according to which the group that wishes to exclude current citizens secedes from the territory in which those citizens reside. I argue that the wrongness of territorial exclusion explains why there is no pro tanto right for a state to exclude immigrants, because otherwise there would be a pro tanto right for the state to kick people out by seceding from the territory they inhabit. Because kicking people out like this is typically wrong, borders cannot be closed. (shrink)

The potential to collect brain data more directly, with higher resolution, and in greater amounts has heightened worries about mental and brain privacy. In order to manage the risks to individuals posed by these privacy challenges, some have suggested codifying new privacy rights, including a right to “mental privacy.” In this paper, we consider these arguments and conclude that while neurotechnologies do raise significant privacy concerns, such concerns are—at least for now—no different from those raised by other well-understood data collection (...) technologies, such as gene sequencing tools and online surveillance. To better understand the privacy stakes of brain data, we suggest the use of a conceptual framework from information ethics, Helen Nissenbaum’s “contextual integrity” theory. To illustrate the importance of context, we examine neurotechnologies and the information flows they produce in three familiar contexts—healthcare and medical research, criminal justice, and consumer marketing. We argue that by emphasizing what is distinct about brain privacy issues, rather than what they share with other data privacy concerns, risks weakening broader efforts to enact more robust privacy law and policy.

Motion—and, in particular, local motion or change in location—plays a central role in Kenelm Digby’s natural philosophy and in his arguments for the immateriality of the soul. Despite this, Digby’s account of what motion consists in has yet to receive much scholarly attention. In this paper, I advance a novel interpretation of Digby on motion. According to it, Digby holds that for a body to move is for it to divide from and unify with other bodies. This is a view (...) of motion—as change in relations of parthood—that Alison Peterman attributes to Digby’s contemporary and acquaintance, Margaret Cavendish. Having shown that Digby’s presentation of the view predates Cavendish’s by more than a decade, I make a case that Digby’s work influenced Cavendish’s on this topic. In developing and defending my reading, I consider to what extent the Digbean account of motion and the arguments for it accord with the ideals of the mechanical philosophy emerging in the early modern period.

I ask you to X. You now have a reason to X. My request gave you a reason. How? One unpopular theory is the epistemic account, according to which requests do not create any new reasons but instead simply reveal information. For instance, my request that you X reveals that I desire that you X, and my desire gives you a reason to X. Peter Schaber has recently attacked both the epistemic account and other theories of the reason-giving force of (...) requests. Schaber defends a new theory of the reason-giving force of requests according to which request give reasons because it is valuable for requesters and requestees that requests have this power. In this paper I argue that Schaber's attack on the epistemic account fails, and that his own theory ought to be rejected because it faces compelling objections. (shrink)

Plato's dialogues frequently criticize traditional Greek myth, yet Plato also integrates myth with his writing. Daniel S. Werner confronts this paradox through an in-depth analysis of the Phaedrus, Plato's most mythical dialogue. Werner argues that the myths of the Phaedrus serve several complex functions: they bring nonphilosophers into the philosophical life; they offer a starting point for philosophical inquiry; they unify the dialogue as a literary and dramatic whole; they draw attention to the limits of language and the limits (...) of knowledge; and they allow Plato to co-opt cultural authority as a way of defining and legitimating the practice of philosophy. Platonic myth, as a species of traditional tale, is thus both distinct from philosophical dialectic and similar to it. Ultimately, the most powerful effect of Platonic myth is the way in which it leads readers to participate in Plato's dialogues and to engage in a process of self-examination. (shrink)

This book is a study of the role of intellect in human action as described by Thomas Aquinas. One of its primary aims is to compare the interpretation of Aristotle by Aquinas with the lines of interpretation offered in contemporary Aristotelian scholarship. The book seeks to clarify the problems involved in the appropriation of Aristotle's theory by a Christian theologian, including such topics as the practical syllogism and the problems of akrasia. Westberg argues that Aquinas was much closer to Aristotle (...) than is often recognized, and he puts forward important new interpretations of the relation of intellect and will in the stages of intention, deliberation, decision, and execution. In the concluding section of the book, he shows how this new interpretation yields fruitful insights on a range of theological topics, including sin, law, love, and the moral virtues. (shrink)

Abstract This paper offers an appraisal of Phillip Pettit's approach to the problem how a merely finite set of examples can serve to represent a determinate rule, given that indefinitely many rules can be extrapolated from any such set. I argue that Pettit's so-called ethnocentric theory of rule-following fails to deliver the solution to this problem he sets out to provide. More constructively, I consider what further provisions are needed in order to advance Pettit's general approach to the problem. I (...) conclude that what is needed is an account that, whilst it affirms the view that agents' responses are constitutively involved in the exemplification of rules, does not allow such responses the pride of place they have in Pettit's theory.

Can a liberal state exclude illiberal immigrants in order to preserve its liberal status? Hrishikesh Joshi has argued that liberalism cannot require a commitment to open borders because this would entail that liberalism is committed to its own demise in circumstances in which many illiberal immigrants aim to immigrate into a liberal society. I argue that liberalism is committed to its own demise in certain circumstances, but that this is not as bad as it may appear. Liberalism’s commitment to its (...) own demise is merely a reflection of the fact that it must take into account the rights of outsiders, not just the rights of existing citizens, and of the fact that circumstances of injustice can sometimes leave liberal societies with no correct choice.

This paper aims to understand Hegel’s claim in the introduction to his Philosophy of Mind that mind is an actualization of the Idea and argues that this claim provides us with a novel and defensible way of understanding Hegel’s naturalism.

In the first part of the paper, I present an (...) interpretation of Hegel’s method in which life plays a central role. In the second part of the paper, I develop Hegel’s method by providing a reading of Hegel’s Subjective Spirit, focusing on the sections ‘Anthropology’ and ‘Phenomenology’ in particular, arguing that they display the dialectic between life and cognition outlined by Hegel’s Idea.

This essay considers the critical response to Hegel's view of Socrates we find in Kierkegaard's dissertation, The Concept of Irony. I argue that this dispute turns on the question whether or not the examination of particular thinkers enters into Socrates’ most basic aims and interests. I go on to show how Kierkegaard's account, which relies on an affirmative answer to this question, enables him to provide a cogent defence of Socrates' philosophical practice against Hegel's criticisms.

According to ethical objectivism, what a person should do depends on the facts, as opposed to their perspective on the facts. A long-standing challenge to this view is that it fails to accommodate the role that norms play in guiding a person’s action. Roughly, if the facts that determine what a person should do lie beyond their ken, they cannot inform a person’s deliberations. This paper explores two recent developments of this line of thought. Both focus on the epistemic counterpart (...) to ethical objectivism, according to which what a person should believe depends on the facts, as opposed to their perspective on the facts. The suggestion in each case is that epistemic objectivism faces a distinctive problem in accommodating guidance. Insofar as objectivism concerning the epistemic domain stands or falls with objectivism concerning the ethical domain, this is a problem for objectivism more generally. In this paper, I show that those arguments are not successful. The upshot is that the objectivist – whether ethical or epistemic – need not reject the idea that norms serve a guiding function.

The _Physics_ is a foundational work of western philosophy, and the crucial one for understanding Aristotle's views on matter, form, essence, causation, movement, space, and time. This richly annotated, scrupulously accurate, and consistent translation makes it available to a contemporary English reader as no other does—in part because it fits together seamlessly with other closely associated works in the New Hackett Aristotle series, such as the _Metaphysics_, _De Anima_, and forthcoming _De Caelo_ and _On Coming to Be and Passing Away_. (...) Eventually the series will include all of Aristotle's works. Sequentially numbered endnotes provide the information most needed at each juncture, while a detailed Index of Terms indicates places where focused discussion of key notions occurs.

Despite myriad controversies about reasons, two theses are frequently taken for granted: (i) reasons are sources of normative support for actions, attitudes, etc; and (ii) reasons, at least in simple, paradigmatic cases, consist in atomic facts. Call this conjunction “the atomic view.” Against this, we advocate what we call “the cluster view,” on which even in the simplest cases, the normative support for an action or attitude is typically provided by a whole cluster of facts. Moreover, many of these facts (...) are on an explanatory par—they each play the same kind of role in explaining why there is normative support for the action or attitude in question. We show that presupposition of the atomic view generates unnecessary (psuedo-)puzzles⁠—about topics such as rationality, moral worth, and doxastic justification⁠—that can be largely (dis)solved with the cluster view in place. The cluster view’s ability to do this constitutes an argument in its favor, beyond intuitive considerations that we also adduce. (shrink)

There has recently been a focus on the question of statue removalism. This concerns what to do with public history statues that honour or otherwise celebrate ethically bad historical figures. The specific wrongs of these statues have been understood in terms of derogatory speech, inapt honours, or supporting bad ideologies. In this paper I understand these bad public history statues as history, and identify a distinctive class of public history-specific wrongs. Specifically, public history plays an important identity-shaping role, and bad (...) public history can commit specifically ontic injustice. Understanding bad public history in terms of ontic injustice helps understand not just to address bad public history statues, but also understand the value of public history more broadly. (shrink)

The goal of this paper is to review and critically discuss the philosophical aspects of probabilistic seismic hazard analysis (PSHA). Given that estimates of seismic hazard are typically riddled with uncertainty, diferent epistemic values (related to the pursuit of scientifc knowledge) compete in the selection of seismic hazard models, in a context infuenced by non-epistemic values (related to practical goals and aims) as well. We frst distinguish between the diferent types of uncertainty in PSHA. We claim that epistemic and nonepistemic (...) considerations are closely related in the selection of the appropriate estimate of seismic hazard by the experts. Finally, we argue that the division of scientifc responsibility among the experts can lead to responsibility gaps. This raises a problem for the ownership of the results (“no one’s model” problem) similar to the “problem of many hands” in the ethics of technology. We conclude with a plea for a close collaboration between philosophy and engineering. (shrink)

There are two distinct approaches to Bayesian modelling in cognitive science. Black-box approaches use Bayesian theory to model the relationship between the inputs and outputs of a cognitive system without reference to the mediating causal processes; while mechanistic approaches make claims about the neural mechanisms which generate the outputs from the inputs. This paper concerns the relationship between these two approaches. We argue that the dominant trend in the philosophical literature, which characterizes the relationship between black-box and mechanistic approaches to (...) Bayesian cognitive science in terms of the dichotomy between instrumentalism and realism, is misguided. We propose that the two distinctions are orthogonal: black-box and mechanistic approaches to Bayesian modelling can each be given either an instrumentalist or a realist interpretation. We argue that the current tendency to conflate black-box approaches with instrumentalism and mechanistic approaches with realism stems from unwarranted assumptions about the nature of scientific explanation, the ontological commitments of scientific theories, and the role of abstraction and idealization in scientific models. We challenge each of these assumptions to reframe the debates over Bayesian modelling in cognitive science. (shrink)
