Current COVID-19 pandemic and previous SARS/MERS outbreaks have caused a series of major crises to global public health. We must integrate the large and exponentially growing amount of heterogeneous coronavirus data to better understand coronaviruses and associated disease mechanisms, in the interest of developing effective and safe vaccines and drugs. Ontologies have emerged to play an important role in standard knowledge and data representation, integration, sharing, and analysis. We have initiated the development of the community-based Coronavirus Infectious Disease Ontology (CIDO). (...) As an Open Biomedical Ontology (OBO) library ontology, CIDO is an open source and interoperable with other existing OBO ontologies. In this article, the general architecture and the design patterns of the CIDO are introduced, CIDO representation of coronaviruses, phenotypes, anti-coronavirus drugs and medical devices (e.g. ventilators) are illustrated, and an application of CIDO implemented to identify repurposable drug candidates for effective and safe COVID-19 treatment is presented.

The current COVID-19 pandemic and the previous SARS/MERS outbreaks of 2003 and 2012 have resulted in a series of major global public health crises. We argue that in the interest of developing effective and safe vaccines and drugs and to better understand coronaviruses and associated disease mechenisms it is necessary to integrate the large and exponentially growing body of heterogeneous coronavirus data. Ontologies play an important role in standard-based knowledge and data representation, integration, sharing, and analysis. Accordingly, we initiated the (...) development of the community-based Coronavirus Infectious Disease Ontology in early 2020. -/- As an Open Biomedical Ontology (OBO) library ontology, CIDO is open source and interoperable with other existing OBO ontologies. CIDO is aligned with the Basic Formal Ontology and Viral Infectious Disease Ontology. CIDO has imported terms from over 30 OBO ontologies. For example, CIDO imports all SARS-CoV-2 protein terms from the Protein Ontology, COVID-19-related phenotype terms from the Human Phenotype Ontology, and over 100 COVID-19 terms for vaccines (both authorized and in clinical trial) from the Vaccine Ontology. CIDO systematically represents variants of SARS-CoV-2 viruses and over 300 amino acid substitutions therein, along with over 300 diagnostic kits and methods. CIDO also describes hundreds of host-coronavirus protein-protein interactions (PPIs) and the drugs that target proteins in these PPIs. CIDO has been used to model COVID-19 related phenomena in areas such as epidemiology. The scope of CIDO was evaluated by visual analysis supported by a summarization network method. CIDO has been used in various applications such as term standardization, inference, natural language processing (NLP) and clinical data integration. We have applied the amino acid variant knowledge present in CIDO to analyze differences between SARS-CoV-2 Delta and Omicron variants. CIDO's integrative host-coronavirus PPIs and drug-target knowledge has also been used to support drug repurposing for COVID-19 treatment. -/- CIDO represents entities and relations in the domain of coronavirus diseases with a special focus on COVID-19. It supports shared knowledge representation, data and metadata standardization and integration, and has been used in a range of applications. (shrink)

This chapter looks at the discussion of materialism in John Locke’s Essay concerning Human Understanding, and then at parts of the Anglophone reaction to those discussions. It considers the early criticisms of Locke by Edward Stillingfleet and the anonymous author of three sets of Remarks on Locke’s Essay. It then looks at some other ways in which readers reacted to Locke’s discussions: the views of Anthony Collins and John Toland, which one might be tempted to think of as Lockean (...) materialism; William Carroll’s reading of Locke as a Spinozistic materialist; and the dualistic Lockeanism of William Duncan’s Lockean logic textbook.

According to John Martin Fischer and Anthony Brueckner’s unique version of the deprivation approach to accounting for death’s badness, it is rational for us to have asymmetric attitudes toward prenatal and posthumous nonexistence. In previous work, I have defended this approach against a criticism raised by Jens Johansson by attempting to show that Johansson’s criticism relies on an example that is incoherent. Recently, Duncan Purves has argued that my defense reveals an incoherence not only in Johansson’s example but (...) also in Fischer and Brueckner’s approach itself. Here I argue that by paying special attention to a certain feature of Fischer and Brueckner’s approach, we can dispense of not only Johansson’s criticism but also of Purves’s objection to Fischer and Brueckner’s approach.

To be acquainted with something (in the philosophical sense of “acquainted” discussed here) is to be directly aware of it. The idea that we are acquainted with certain things we experience has been discussed throughout the history of Western Philosophy, but in the early 20th century it gained especially focused attention among analytic philosophers who drew their inspiration from Bertrand Russell's work on acquaintance. Since then, many philosophers—particularly those working on self‐knowledge or perception—have used the notion of acquaintance to explain (...) various facts about human experience and knowledge. In this paper, I offer an overview of this work, with particular focus on the resurgent literature on acquaintance in contemporary analytic philosophy. After more fully explaining what acquaintance is (or is supposed to be), I describe some reasons for thinking that we are indeed acquainted with certain things we experience, and then I survey some of the facts about experience and knowledge that acquaintance may help explain.

A powerful argument against the counterfactual comparative account of harm is that it cannot distinguish harming from failing to benefit. In reply to this problem, I suggest a new account of harm. The account is a counterfactual comparative one, but it counts as harms only those events that make a person occupy his level of well-being at the world at which the event occurs. This account distinguishes harming from failing to benefit in a way that accommodates our intuitions about the (...) standard problem cases. In laying the groundwork for this account, I also demonstrate that rival accounts of harm are able to distinguish harming from failing to benefit only if, and because, they also appeal to the distinction between making upshots happen and allowing upshots to happen. One important implication of my discussion is that preserving the moral asymmetry between harming and failing to benefit requires a commitment to the existence of a metaphysical and moral distinction between making and allowing.

“We are animals.” That’s what animalists say—that’s their slogan. But what animalists mean by their slogan varies. Many animalists are adamant that what they mean—and, indeed, what the true animalist thesis is—is that we are identical to animals (human animals, to be precise). But others say that’s not enough. They say that the animalist thesis has to be something more—perhaps that we are essentially or most fundamentally human animals. This paper argues that, depending on how we understand it, animalism is (...) either false or uninteresting. If animalism is just the claim that we are identical to animals, then it is uninteresting. For it doesn’t provide an answer to the question it’s meant to address. On the other hand, if animalism entails a stronger claim, such as that we are essentially animals, then animalism is false. Either way, we should set animalism aside. (shrink)

As I walk into a restaurant to meet up with a friend, I look around and see all sorts of things in my immediate environment—tables, chairs, people, colors, shapes, etc. As a result, I know of these things. But what is the nature of this knowledge? Nowadays, the standard practice among philosophers is to treat all knowledge, aside maybe from “know-how”, as propositional. But in this paper I will argue that this is a mistake. I’ll argue that some knowledge is (...) constituted, not by beliefs toward propositions, but by awareness of properties and objects. Seeing isn’t believing, but it is knowing. After further characterizing this type of knowledge, I will make the case for it. Then I will consider a variety of objections. Finally, I will indicate how our recognition of this knowledge may answer other questions, and solve other problems, in philosophy. (shrink)

I can be aware of myself, and thereby come to know things about myself, in a variety of different ways. But is there some special way in which I—and only I—can learn about myself? Can I become aware of myself by introspecting? Do I somehow show up in my own conscious experiences? David Hume and most contemporary philosophers say no. They deny that the self shows up in experience. However, in this paper I appeal to research on schizophrenia—on thought insertion, (...) in particular—to argue that Hume and his follows are wrong: The self does, in fact, show up in experience. (shrink)

It seems like experience plays a positive—even essential—role in generating some knowledge. The problem is, it’s not clear what that role is. To see this, suppose that when your visual system takes in information about the world around you it skips the experience step and just automatically and immediately generates beliefs in you about your surroundings. A lot of philosophers think that, in such a case, you would (or at least could) still know, via perception, about the world around you. (...) But then that raises the question: What epistemic role was the experience playing? How did it contribute to your knowledge of your surroundings? Philosophers have given many different answers to these questions. But, for various reasons, none of them has really stuck. In this paper I offer and defend a different answer to these questions—a solution to the problem—which avoids the pitfalls of other answers. I argue that experience is, all by itself, a kind of knowledge—it’s what Bertrand Russell (1912) calls “knowledge of things”. So I argue that experience helps generate knowledge simply by being knowledge. (shrink)

This paper has three main goals. First, to motivate a puzzle about how ignorance-expressing terms like maybe and if interact: they iterate, and when they do they exhibit scopelessness. Second, to argue that there is an ambiguity in our theoretical toolbox, and that exposing that opens the door to a solution to the puzzle. And third, to explore the reach of that solution. Along the way, the paper highlights a number of pleasing properties of two elegant semantic theories, explores some (...) meta-theoretic properties of dynamic notions of meaning, dips its toe into some hazardous waters, and offers characterization theorems for the space of meanings an indicative conditional can have.

When it comes to personal identity, two approaches have long ruled the roost. The first is the psychological approach, which has it that our persistence through time consists in the continuance of certain of our psychological traits, such as our memories, beliefs, desires, or personality. The second is the biological approach, according to which personal persistence consists in continuity in our physical or biological makeup. Amid the bipartite reign of these approaches, a third contender has emerged: the phenomenal approach. On (...) this approach, personal persistence consists in continuity in phenomenal consciousness or the capacity for phenomenal consciousness. In this paper I will introduce and defend a new argument for the phenomenal approach. In the process, I will argue against the psychological and biological approaches. I will also address some lingering questions and outline further ways to develop the phenomenal approach. (shrink)

A common criticism of the use of algorithms in criminal justice is that algorithms and their determinations are in some sense ‘opaque’—that is, difficult or impossible to understand, whether because of their complexity or because of intellectual property protections. Scholars have noted some key problems with opacity, including that opacity can mask unfair treatment and threaten public accountability. In this paper, we explore a different but related concern with algorithmic opacity, which centers on the role of public trust in grounding (...) the legitimacy of criminal justice institutions. We argue that algorithmic opacity threatens the trustworthiness of criminal justice institutions, which in turn threatens their legitimacy. We first offer an account of institutional trustworthiness before showing how opacity threatens to undermine an institution’s trustworthiness. We then explore how threats to trustworthiness affect institutional legitimacy. Finally, we offer some policy recommendations to mitigate the threat to trustworthiness posed by the opacity problem.

Bare plural generic sentences pervade ordinary talk. And yet it is extremely controversial what semantics to assign to such sentences. In this paper, I achieve two tasks. First, I develop a novel classification of the various standard uses to which bare plurals may be put. This “variety data” is important—it gives rise to much of the difficulty in systematically theorizing about bare plurals. Second, I develop a novel account of bare plurals, the radical account. On this account, all bare plurals (...) fail to express propositions. The content of a bare plural has to be pragmatically “completed” by a speaker in order for her to make an assertion. At least the content of a quantifier expression has to be supplied. But sometimes, the content of a sentential operator or modal verb is also supplied. The radical account straightforwardly explains the variety data: Speakers’ communicative intentions vary wildly across different contexts. (shrink)

David Gauthier thinks agents facing a prisoner's dilemma ('pd') should find it rational to dispose themselves to co-operate with those inclined to reciprocate (i.e., to acquire a constrained maximizer--'cm'--disposition), and to co-operate with other 'cmers'. Richmond Campbell argues that since dominance reasoning shows it remains to the agent's advantage to defect, his co-operation is only rational if cm "determines" him to co-operate, forcing him not to cheat. I argue that if cm "forces" the agent to co-operate, he is not acting (...) at all, never mind rationally. Thus, neither author has shown that co-operation is rational action in a pd. (shrink)

When we experience the world – see, hear, feel, taste, or smell things – we gain all sorts of knowledge about the things around us. And this knowledge figures heavily in our reasoning about the world – about what to think and do in response to it. But what is the nature of this knowledge? On one commonly held view, all knowledge is constituted by beliefs in propositions. But in this paper I argue against this view. I argue that some (...) knowledge is constituted, not by beliefs in propositions, but by awareness of properties and objects. To make my case, I focus on the role of visual perception in reasoning. I start by introducing a principle about the relationship between knowledge and reasoning, which says that to learn something new by reasoning, one must know the bases of one’s reasoning. Then I argue that in some cases of genuine, knowledge-conferring reasoning, the bases of our reasoning are not propositions that we believe; rather, they’re properties or objects that we see. Thus, I conclude that some such knowledge is non-propositional and is rather what some call “knowledge of things”. (shrink)

It is argued that standard accounts of the epistemology of religious commitmentfail to be properly sensitive to certain important features of the nature of religious conviction. Once one takes these features of religious conviction seriously, then it becomes clear that we are not to conceive of the epistemology of religious conviction along completely rational lines.But the moral to extract from this is not fideism, or even a more moderate proposal that casts the epistemic standing of basic religious beliefs along nonrational (...) lines. Rather, one needs to recognise that in an important sense religious convictions are not beliefs at all, but that this is compatible with the idea that many other religious commitments are beliefs. This picture of the nature of religious commitment is shown to fit snugly with the Wittgensteinian account of hinge commitments, such that all rational belief essentially presupposes certain basic arational hinge commitments, along lines originally suggested by John Henry Newman. We are thus able to marshal a parity-style argument in defence of religious commitment. Although religious belief presupposes basic arational religious convictions, it is not on this score epistemically amiss since all belief presupposes basic arational convictions, or hinge commitments. The resulting view of the epistemology of religious commitment is a position I call quasi-fideism. (shrink)

In virtue of what do things persist through time? Are there criteria of their identities through time? Anti-criterialists say no. One prominent challenge to anti-criterialism comes in two steps. The first step is to show that anti-criterialists are committed specifically to the claim that there are no informative metaphysically sufficient conditions for identity through time. The second step is to show that this commitment yields absurd results. Each step of this challenge is open to objection. However, in what follows, I (...) will refortify this challenge to anti-criterialism by offering new reasons to take each step. (shrink)

Subjectivity is that feature of consciousness whereby there is something it is like for a subject to undergo an experience. One persistent challenge in the study of consciousness is to explain how subjectivity relates to, or arises from, purely physical brain processes. But, in order to address this challenge, it seems we must have a clear explanation of what subjectivity is in the first place. This has proven challenging in its own right. For the nature of subjectivity itself seems to (...) resist straightforward characterization. In this paper, I won't address how subjectivity relates to the physical. Instead, I'll address subjectivity itself. I'll do this by introducing and defending a model of subjectivity based on self-acquaintance. My model does not purport to reduce, eliminate, or naturalize subjectivity, but it does make subjectivity more tractable, less paradoxical, and perhaps less dubious to those averse to obscurity.

Thomas Hobbes often includes powers and abilities in his descriptions of the world. Meanwhile, Hobbes’s philosophical picture of the world appears quite reductive, and he seems sometimes to say that nothing exists but bodies in motion. In more extreme versions of such a picture, there would be no room for powers. Hobbes is not an eliminativist about powers, but his view does tend toward ontological minimalism. It would be good to have an account of what Hobbes thinks powers are, and (...) how they fit into his understanding of the world. In this chapter, I investigate Hobbes’s account of the metaphysics of powers and abilities. Section 1 considers three important aspects of Hobbes’s account of powers: the connection between powers and causes; the modal aspects of powers; and the connection between powers and motions. Sections 2 and 3 then consider interpretive arguments about whether Hobbes identifies powers with underlying corporeal features. (shrink)

A review of Anthony Appiah's Experiments in Ethics.

Recent studies have shown that recidivism scoring algorithms like COMPAS have significant racial bias: Black defendants are roughly twice as likely as white defendants to be mistakenly classified as medium- or high-risk. This has led some to call for abolishing COMPAS. But many others have argued that algorithms should instead be given access to a defendant's race, which, perhaps counterintuitively, is likely to improve outcomes. This approach can involve either establishing race-sensitive risk thresholds, or distinct racial ‘tracks’. Is there a (...) moral difference between these two approaches? We first consider Deborah Hellman's view that the use of distinct racial tracks (but not distinct thresholds) does not constitute disparate treatment since the effects on individuals are indirect and does not rely on a racial generalization. We argue that this is mistaken: the use of different racial tracks seems both to have direct effects on and to rely on a racial generalization. We then offer an alternative understanding of the distinction between these two approaches—namely, that the use of different cut points is to the counterfactual comparative disadvantage, ex ante, of all white defendants, while the use of different racial tracks can in principle be to the advantage of all groups, though some defendants in both groups will fare worse. Does this mean that the use of cut points is impermissible? Ultimately, we argue, while there are reasons to be skeptical of the use of distinct cut points, it is an open question whether these reasons suffice to make a difference to their moral permissibility.

Grey zone attacks tend to paralyze response for two reasons. First, they present us with choice scenarios of inherently dilemmatic structure, e.g., Prisoners’ Dilemmas and games of chicken, complicated by difficult conditions of choice, such as choice under risk or amid vagueness. Second, they exploit our uncertainty about how much we do or should care about the things under attack¬—each attack is small in effect, but their effects accumulate: how should we decide whether to treat a given attack as something (...) meriting a serious response rather than a mere irritation to be ignored? This chapter brings standard decision theoretic tools to bear on the issues, tools such as the maximization of expected utility principle, and the precautionary principle. But it also develops three innovations. It shows that seeing it as possible to make choices not just of actions given our values, but also choices of values themselves, can extricate us from certain kinds of decision paralysis. It shows how we can rationally regard ourselves as having bright decision lines even when nothing in the circumstance of choice has these lines in its structure. And it shows how certain conflict escalation risks from the former two strategies can be managed by both parties seeing that cooperation can yield a sharable surplus of goods, and that cooperation can be rational upon a rationally defensible change in their values so that each comes to derive utility from the success of both parties. This yields cooperative solutions to what amount to Prisoners’ Dilemmas. The Cold War was prosecuted on the logic of strategic rationality and that part of game theory that is deterrence theory. We need a new logic from decision theorists for the games that constitute grey zone conflict. (shrink)

What are the properties of composite objects, and how do the properties of composite objects and the properties of their proper parts relate to one another? The answers to these questions depend upon which view of composition one adopts. One view, which I call the orthodox view, is that composite objects are numerically distinct from their proper parts, individually and collectively. Another view, known as composition as identity, is that composite objects are numerically identical to their proper parts, taken together. (...) I argue that the orthodox view entails that the intuitive picture of composite objects and their properties that most accept is false. Not so for composition as identity. I also show that all of the available alternatives face serious difficulties. This puts composition as identity at an advantage over the orthodox view, at least when it comes to accounting for the properties of composite objects. (shrink)

This is an introduction to my edited book, the Research Handbook on Liberalism (2024). Some chapters tackle broad, meta-level questions about the coherence and justificatory limits and possibilities of liberalism; others tackle conceptual issues; still others, specific institutional, cultural, historical, and political questions. This introductory chapter is intended to provide a general orientation to these discussions, but also highlight some recurring themes and challenges facing liberalism in an era of rampant inequality, illiberalism, rising autocracies, populism, and massive technological change. I (...) provide a taxonomy of five different kinds of liberalism in play in the field, along with three overarching challenges discussed in the book - the apparent insufficiency, complacency, and self-undermining nature of liberalism. Can contemporary liberalism survive? It can, but not without clearly grasping some of the fundamental challenges it faces today. (shrink)

I am aware of the rain outside, but only in virtue of looking at a weather report. I am aware of my friend, but only because I hear her voice through my phone. Thus, there are some things that I’m aware of, but only indirectly. Many philosophers believe that there are also some things of which I am directly aware. The most plausible candidates are experiences such as pains, tickles, visual sensations, etc. In fact, the philosophical consensus seems to be (...) that experiences are the only plausible candidates for acquaintance. But I will argue that we are also acquainted with ourselves. After outlining what it means to be acquainted with oneself, I will introduce, develop, and defend a commonly used test for acquaintance. Then I will apply this test to us and show that we pass. I will consider various objections to my argument. But ultimately I will conclude that we can be, and often are, acquainted with ourselves.

The two most common accounts of the category of relation are the "toothpick" account of relations and the inherent attribute view of relations. In this essay, I present and defend another traditional account of relations, according to which they are neither real things in their own right nor inherent attributes of things. Instead, they are creatures of reason grounded in objective, non-relational attributes of things. I illustrate this view by reference to the major classes of relations that have some claim (...) to be real or objective - grounded in being. In an appendix, I use this account to discuss what it means to say that the persons of the Trinity are "substantial relations.". (shrink)

It is widely thought that grounding is a hyperintensional phenomenon. Unfortunately, the term ‘hyperintensionality’ has been doing double-duty, picking out two distinct phenomena. This paper clears up this conceptual confusion. We call the two resulting notions hyperintensionalityGRND and hyperintensionalityTRAD. While it is clear that grounding is hyperintensionalGRND, the interesting question is whether it is hyperintensionalTRAD. We argue that given well-accepted constraints on the logical form of grounding, to wit, that grounding is irreflexive and asymmetric, grounding is hyperintensionalTRAD only if one (...) endorses a sentential operator view of grounding. We argue that proponents of the sentential operator view will need to distinguish two importantly different kinds of hyperintensionalityTRAD—weak and strong—and we offer them a way to do so.

In his Enquiry concerning the Principles of Morals David Hume said that a group of earlier modern philosophers, beginning with Malebranche, held that morality was founded on relations. In this paper I follow up on that suggestion by investigating pre-Humean views in moral philosophy according to which morality is founded on relations. I do that by looking at the work of Nicolas Malebranche, John Locke, and Samuel Clarke. Each of them talked prominently about relations in their accounts of basic aspects (...) of morality. Beyond that, each of them turns out to have held both metaphysical and epistemological views that might be described as founding morality on relations. Despite the definite differences between the three philosophers’ approaches, Hume does seem to have noticed a genuine connection here—even though he himself tended to ignore significant versions of this approach when criticizing it.

An overview of the import of disjunctivism to the problem of radical scepticism is offered. In particular, the disjunctivist account of perceptual experience is set out, along with the manner in which it intersects with related positions such as naïve realism and intentionalism, and it is shown how this account can be used to a motivate an anti-sceptical proposal. In addition, a variety of disjunctivism known as epistemological disjunctivism is described, and it is explained how this proposal offers a further (...) way of responding to radical scepticism.

Autonomous and automatic weapons would be fire and forget: you activate them, and they decide who, when and how to kill; or they kill at a later time a target you’ve selected earlier. Some argue that this sort of killing is always wrong. If killing is to be done, it should be done only under direct human control. (E.g., Mary Ellen O’Connell, Peter Asaro, Christof Heyns.) I argue that there are surprisingly many kinds of situation where this is false and (...) where the use of Automated Weapons Systems would in fact be morally required. These include cases where a) once one has activated a weapon expected then to behave lethally, it would be appropriate to let it continue because this is part of a plan whose goodness one was best positioned to evaluate before activating the weapon; b) one expects better long-term consequences from allowing it to continue; c) allowing it to continue would express a decision you made to be resolute, a decision that could not have advantaged you had it not been true that you would carry through with it; d) the weapon is mechanically not recallable, so that, to not allow it to carry through, you would have had to refrain from activating it in the first place, something you expected would have disastrous consequences; e) you must deputize necessary killings to autonomous machines in order to protect yourself from guilt you shouldn’t have to bear; f) it would be morally better for the burden of responsibility for the killing to be shared among several agents, and the agents deputizing killing to machines can do this, especially where it’s not predictable which machine will be successful; g) a killing would be morally better done with elements of randomness and lack of deliberation, and a (relatively stupid) machine could do this where a person could not; h) the machine would be acting as a Doomsday Device, so that it could not have had its hoped for deterrent effect had you not ensured that you would be unable to recall it if enemy action activated it; i) letting it carry through is a necessary part of its own learning process, and you expect that this learning will have salutary effects later on; j) human intervention in the machine’s operation would disastrously impair its precision, or its speed and efficiency; k) using non-automated methods would require human resources you just don’t have in a task that nevertheless must be done (e.g., using land-mines to protect remote installations); l) the weapon has such horrible and indiscriminate power that it is doubtful whether it could be actually used in ways compatible with International Humanitarian Law and the Laws of War, which require that weapons be used only in ways respecting distinctness, necessity and proportionality, but its threat of use could respect these principles in affording deterrence provided human error cannot lead to their accidental deployment, this requiring that they be controlled by carefully designed autonomous and automatic systems. I then consider objections based on conceptions of human dignity and find that very often dignity too is best served by autonomous machine killing. Examples include saving your village by activating a robot to kill invading enemies who would inflict great indignity on your village, using a suicide robot to save yourself from a less dignified death at enemy hands, using a robotic drone to kill someone otherwise not accessible in order to restore dignity to someone this person killed and to his family, and using a robot to kill someone who needs killing, but the killing of whom by a human executioner would soil the executioner’s dignity. I conclude that what matters in rightful killing isn’t necessarily that it be under the direct control of a human, but that it be under the control of morality; and that could sometimes require use of an autonomous or automated device. (This paper was formerly called "Fire and Forget: A Defense of the Use of Autonomous Weapons in War" on Philpapers; the current title is the title of the published version.). (shrink)

Suppose that you're lying in bed. You just woke up. But you're alert. Your mind is clear and you have no distractions. As you lie there, you think to yourself, ‘2 + 2 = 4.’ The thought just pops into your head.

First I will show that thought and perception have temporal constraints whereby your thinking or perceiving in the above scenarios implies that you exist through a temporally.. (shrink)

What does the 'colonialist' reading of Locke's political theory suggest about the relationship between liberalism and colonialism in general, as well as the pre-history of liberalism in particular?

Resolving to finish reading a novel, staying true to your punk style, or dedicating your life to an artistic project: these are examples of aesthetic commitments. I develop an account of the nature of such commitments, and I argue that they are significant insofar as they help us manage the temporally extended nature of our aesthetic agency and our relationships with aesthetic objects. At the same time, focusing on aesthetic commitments can give us a better grasp on the nature of (...) aesthetic normativity; this is because, in making aesthetic commitments, we are capable of giving aesthetic concerns the weight of obligation. I argue that appealing to aesthetic commitments allows us to account for the existence of aesthetic obligations as well as their grounding. I conclude by arguing that, although the aesthetic domain is a domain of play and freedom of choice, there is nevertheless an important place in it for both aesthetic commitments and the aesthetic obligations they generate.

Jack Spencer has recently argued for the striking thesis that, possibly, an agent is able to do the impossible—that is, perform an action that is metaphysically impossible for that person to perform. Spencer bases his argument on (Simple G), a case in which it is impossible for an agent G to perform some action but, according to Spencer, G is still intuitively able to perform that action. I reply that we would have to give up at least four action-theoretical principles (...) if we accept that G is able to do the impossible. We may be best off retaining the principles and thus rejecting Spencer's intuition that G is able to do the impossible. I then consider an argument for the claim that G is able to do the impossible that goes through the Snapshot Principle. I, however, deny that any true variant of the Snapshot Principle shows that G is able to do the impossible. Moreover, the counterexample to the Snapshot Principle that I develop also suggests that G is unable to do the impossible in (Simple G). The most natural explanation for why an agent is unable to perform some action in this counterexample extends to (Simple G). Next, I develop three error theories for why we might initially share Spencer's intuition that G is able to do the impossible in (Simple G). Finally, I consider a couple other "G-cases" of Spencer's and find them all wanting. Perhaps we are unable to do the impossible. (shrink)

Draft for the Oxford Handbook of Margaret Cavendish (edited by Julie Crawford with Jacqueline Broad). -/- This chapter looks at Margaret Cavendish's treatment of the supernatural, beginning by asking how she distinguishes the natural from the supernatural, and then by examining her treatment of a series of alleged supernatural beings: fairies, ghosts, witches, the human supernatural soul, angels, and God. Throughout, it argues that Cavendish's approach to the supernatural is often similar to Thomas Hobbes's.

This paper defends Flatland—the view that there exist neither determination nor dependence relations, and that everything is therefore fundamental—from the objection from explanatory inefficacy. According to that objection, Flatland is unattractive because it is unable to explain either the appearance as of there being determination relations, or the appearance as of there being dependence relations. We show how the Flatlander can meet the first challenge by offering four strategies—reducing, eliminating, untangling and omnizing—which, jointly, explain the appearance as of there being (...) determination relations where no such relations obtain. Since, plausibly, dependence relations just are asymmetric determination relations, we argue that once we come mistakenly to believe that there exist determination relations, the existence of other asymmetries (conceptual and temporal) explains why it appears that there are dependence relations.

It is widely thought that stealing, trading and destroying cultural artifacts in time of war are inherently immoral actions, and that it is right that they be treated as war crimes, which, indeed, they currently are. But oppressive cultures have their heritage and cultural artifacts too, in the form of monuments, sites of worship, and so on; and for the oppressed, these things may be awful reminders of their subordination, and may even perpetuate it. This chapter suggests that, since cultural (...) objects can be both tools and symbols of unjust oppression, their theft and destruction ought to be seen as appropriate when this would be a means of overcoming oppression. Whatever current law may say, in these instances, it would be morally inappropriate to count such acts as war crimes. Furthermore, it is bizarre that theft and destruction of cultural property are counted as war crimes when soldiers killing each other is not (due to combatant immunity). Surely killing is worse than property destruction and theft. It is therefore argued that, where possible, it would be better for conflicts to be fought using the latter methods. Finally, the chapter responds to many objections to using theft and destruction of cultural property as a method of warfare. E.g. to the objection that such property has timeless, trans-cultural, aesthetic, historical and scientific value, it is replied that justice is a more important value; and to the objection that these practices amount to cultural genocide it is replied that unjust cultures have no right to exist unmodified. (This chapter was formerly entitled: "Culture Weaponized: A Contrarian Theory of the Sometime Appropriateness of the Destruction, Theft and Trade of Art and Cultural Artifacts in Armed Conflict." The PhilPapers archived version is a pre-penultimate version of the published version.). (shrink)

This is an earlier version of the argument presented as the appendix to the author's final book, Peri Physeos.

This paper investigates Locke’s views about materialism, by looking at the discussion in Essay IV.x. There Locke---after giving a cosmological argument for the existence of God---argues that God could not be material, and that matter alone could never produce thought. In discussing the chapter, I pay particular attention to some comparisons between Locke’s position and those of two other seventeenth-century philosophers, René Descartes and Ralph Cudworth. -/- Making use of those comparisons, I argue for two main claims. The first is (...) that the important argument of Essay IV.x.10 is fundamentally an argument about the causation of perfections. Indeed, Locke gives multiple such arguments in the chapter. My second main claim is that my proposed reading of IV.x is not merely consistent with what Locke says elsewhere about superaddition, but also provides reasons to favor a particular understanding of what superaddition is.

The author presents reasons for thinking that the evil we observe in the world is not even prima facie evidence against the existence of God.

My interest is the kind of philosophical vertigo that is a theme of Cavell’s work on scepticism. This describes the anxiety that is elicited via philosophical engagement with certain kinds of sceptical questions. There is a standing puzzle about this notion of vertigo, however, forcefully pressed, for example, by McDowell. Why should a resolution of the sceptical problem, one that putatively completely undercuts the motivation for scepticism in that domain, nonetheless generate vertigo in this sense? I aim to resolve the (...) puzzle, in a way that I believe underwrites this Cavellian notion, via consideration of Wittgenstein’s remarks on the structure of rational evaluation in his final notebooks, published as On Certainty.

Bertrand Russell [1912] argued that we are acquainted with our experiences. Although this conclusion has generated a lot of discussion, very little has been said about Russell's actual arguments for it. This paper aims to remedy that. I start by spelling out two Russellian arguments for acquaintance. Then I show that these arguments cannot both succeed. For if one is sound, the other isn't. Finally, I weigh our options with respect to these arguments, and defend one option in particular. I (...) argue that we have good reason to believe that we can be, and sometimes are, acquainted with our experiences. (shrink)

Hume said that the reasons that determine the rationality of one's actions are the desires one has when acting: one's actions are rational iff they advance these desires. Thomas Nagel says this entails calling rational, actions absurdly conflicting in aims over time. For one might have reason, in one's current desires, to begin trying to cause states one foresees having reason, in one's foreseen desires, to prevent. Instead, then, real reasons must be timeless, so that current and foreseen reasons cannot (...) conflict. I say the desire theory does not have absurd consequences. A rational agent's desires would rationally evolve, never requiring actions conflicting in aims over time, except where it was instrumentally rational for her to change in her desires, whence such conflicts are rationally appropriate. Further, whatever sorts of things count as real reasons, since reasons can rationally require their own revision, they cannot be necessarily timeless. (shrink)

I argue that Hobbes isn't really a materialist in the early 1640s (in, e.g., the Third Objections to Descartes's Meditations). That is, he doesn't assert that bodies are the only substances. However, he does think that bodies are the only substances we can think about using imagistic ideas.

Hobbes denies in Leviathan that we have an idea of God. He does think, though, that God exists, and does not even deny that we can think about God, even though he says we have no idea of God. There is, Hobbes thinks, another cognitive mechanism by means of which we can think about God. That mechanism allows us only to think a few things about God though. This constrains what Hobbes can say about our knowledge of God, and grounds (...) his belief in a fairly strong version of the thesis that God is incomprehensible. (shrink)

This chapter conceptually analyzes the post-traumatic stress injuries called moral injury, moral fatigue or exhaustion, and broken spirit. It then identifies two puzzles. First, soldiers sometimes sustain moral injury even from doing right actions. Second, they experience moral exhaustion from making decisions even where the morally right choice is so obvious that it shouldn’t be stressful to make it; and even where rightness of decision is so murky that no decision could be morally faulted. The injuries result of mistaken moral (...) self-evaluation. Methods of preventing and treating these injuries are defended, including training in self-forgiveness, moral off-loading of actions and decisions to persons and devices less likely to feel inappropriate guilt, and the use of drugs to prevent such guilt. The foregoing has been about moral injury erroneously resulting from the non-violation of a correct moral code. But the chapter then introduces the concept of moral pseudo-injury—felt moral injury that has in reality resulted from violation of a false moral code, so that no one has really been morally injured. This can be used as a method in warfighting. And since the injuries it produces are illusory, this would be morally superior to physical violence. For it causes less injury to its victims, and should cause less guilt in those who must inflict it. Historical precedents are considered. Finally, our enemies often use moral pseudo-injury against us, in the form of terrorist violence against civilians. Terrorism causes comparatively few harms, yet we mistakenly see it as more morally horrific than conventional combat that causes much worse loss of life among armed forces members. Here we need the nuancing and clarifying power of philosophy to restore a sense of proportion, thence to prevent or therapize the moral pseudo-injury we may experience from these sorts of attacks. (This is a pre-penultimate version of the published version, available from OUP at the external link, which contains minor variances. The paper was earlier known as "PTSD Weaponized: A Theory of Moral Injury"; that now superseded version is archived under "past conferences" on the Center for Ethics and the Rule of Law website.).

Many people believe that the mind is an epistemic refuge of sorts. The idea is that when it comes to certain core mental states, one’s being in such a state automatically puts one in a position to know that one is in that state. This idea has come under attack in recent years. One particularly influential attack comes from Timothy Williamson (2000), who argues that there is no central core of states or conditions—mental or otherwise—to which we are guaranteed epistemic (...) access. In Williamson’s words, we are cognitively homeless. In this paper I will argue that Williamson’s argument for the conclusion that we are cognitively homeless fails. Then I will show that there is a class of phenomenal states that constitutes a substantial cognitive refuge. When all is said and done, I will have both defended and shed light on our cognitive home.

How may nations protect their interests in space if its fragility makes military operations there self-defeating? This essay claims nations are in Prisoners Dilemmas on the matter, and applies David Gauthier’s theories about how it is rational to behave morally—cooperatively—in such dilemmas. Currently space-faring nations should i) enter into co-operative space sharing arrangements with other rational nations, ii) exclude—militarily, but with only terrestrial force—nations irrational or existentially opposed to other nations being in space, and iii) incentivize all nations into co-operation (...) by redistributing some space-generated wealth to nations that might otherwise ruin space. Further, since all nations are rationally incentivized to ever greater dependence on space, and since each, by threatening space, can hold hostage its benefits to all, each can demand resolution of terrestrial discontents with other nations. So each has a rational interest in treating others morally both in space and on terrestrial issues. (shrink)
