From the end of the twelfth century until the middle of the eighteenth century, the concept of a right of necessity –i.e. the moral prerogative of an agent, given certain conditions, to use or take someone else’s property in order to get out of his plight– was common among moral and political philosophers, who took it to be a valid exception to the standard moral and legal rules. In this essay, I analyze Samuel Pufendorf’s account of such a (...) right, founded on the basic instinct of self-preservation and on the notion that, in civil society, we have certain minimal duties of humanity towards each other. I review Pufendorf’s secularized account of natural law, his conception of the civil state, and the function of private property. I then turn to his criticism of Grotius’s understanding of the right of necessity as a retreat to the pre-civil right of common use, and defend his account against some recent criticisms. Finally, I examine the conditions deemed necessary and jointly sufficient for this right to be claimable, and conclude by pointing to the main strengths of this account. Keywords: Samuel Pufendorf, Hugo Grotius, right of necessity, duty of humanity, private property. (shrink)

Reinhardt’s conjecture, a formalization of the statement that a truthful knowing machine can know its own truthfulness and mechanicalness, was proved by Carlson using sophisticated structural results about the ordinals and transfinite induction just beyond the first epsilon number. We prove a weaker version of the conjecture, by elementary methods and transfinite induction up to a smaller ordinal.

We construct a machine that knows its own code, at the price of not knowing its own factivity.

We study the structure of families of theories in the language of arithmetic extended to allow these families to refer to one another and to themselves. If a theory contains schemata expressing its own truth and expressing a specific Turing index for itself, and contains some other mild axioms, then that theory is untrue. We exhibit some families of true self-referential theories that barely avoid this forbidden pattern.

Prior scholarly approaches to meaningful work have largely fallen into two camps. One focuses on identifying how work can contribute to a meaningful life. The other studies the antecedents and outcomes of workers experiencing their work as meaningful. Neither of these approaches, however, captures what people look for when they seek meaningful work—or so I argue. In this paper, I give a new, commitment-based account of meaningful work by focusing on the reasons people have to choose meaningful work over other (...) options. I draw on philosopher Ruth Chang’s account of voluntarist reasons (reasons that arise from an act of the will) to argue that commitments can create distinctive reasons to pursue certain work. It is the presence of these distinctive reasons that makes work meaningful. (shrink)

We argue that C. Darwin and more recently W. Hennig worked at times under the simplifying assumption of an eternal biosphere. So motivated, we explicitly consider the consequences which follow mathematically from this assumption, and the infinite graphs it leads to. This assumption admits certain clusters of organisms which have some ideal theoretical properties of species, shining some light onto the species problem. We prove a dualization of a law of T.A. Knight and C. Darwin, and sketch a decomposition result (...) involving the internodons of D. Kornet, J. Metz and H. Schellinx. A further goal of this paper is to respond to B. Sturmfels’ question, “Can biology lead to new theorems?”. (shrink)

Decision theory has had a long-standing history in the behavioural and social sciences as a tool for constructing good approximations of human behaviour. Yet as artificially intelligent systems (AIs) grow in intellectual capacity and eventually outpace humans, decision theory becomes evermore important as a model of AI behaviour. What sort of decision procedure might an AI employ? In this work, I propose that policy-based causal decision theory (PCDT), which places a primacy on the decision-relevance of predictors and simulations of agent (...) behaviour, may be such a procedure. I compare this account to the recently-developed functional decision theory (FDT), which is motivated by similar concerns. I also address potentially counterintuitive features of PCDT, such as its refusal to condition on observations made at certain times. (shrink)

Elementary patterns of resemblance notate ordinals up to the ordinal of Pi^1_1-CA_0. We provide ordinal multiplication and exponentiation algorithms using these notations.

Recent years have witnessed growing controversy over the “wisdom of the multitude.” As epistemic critics drawing on vast empirical evidence have cast doubt on the political competence of ordinary citizens, epistemic democrats have offered a defense of democracy grounded largely in analogies and formal results. So far, I argue, the critics have been more convincing. Nevertheless, democracy can be defended on instrumental grounds, and this article demonstrates an alternative approach. Instead of implausibly upholding the epistemic reliability of average voters, I (...) observe that competitive elections, universal suffrage, and discretionary state power disable certain potent mechanisms of elite entrenchment. By reserving particular forms of power for the multitude of ordinary citizens, they make democratic states more resistant to dangerous forms of capture than non-democratic alternatives. My approach thus offers a robust defense of electoral democracy, yet cautions against expecting too much from it—motivating a thicker conception of democracy, writ large. (shrink)

Fragmentalism was originally introduced as a new A-theory of time. It was further refined and discussed, and different developments of the original insight have been proposed. In a celebrated paper, Jonathan Simon contends that fragmentalism delivers a new realist account of the quantum state—which he calls conservative realism—according to which: the quantum state is a complete description of a physical system, the quantum state is grounded in its terms, and the superposition terms are themselves grounded in local goings-on about the (...) system in question. We will argue that fragmentalism, at least along the lines proposed by Simon, does not offer a new, satisfactory realistic account of the quantum state. This raises the question about whether there are some other viable forms of quantum fragmentalism. (shrink)

The Gamer’s Dilemma consists of three intuitively plausible but conflicting assertions: (i) Virtual murder is morally permissible. (ii) Virtual child molestation is morally forbidden. (iii) There is no relevant moral difference between virtual murder and virtual child molestation in computer games. Numerous attempts to resolve (or dissolve) the Gamer’s Dilemma line the field of computer game ethics. Mostly, the phenomenon is approached using expressivist argumentation: Reprehensible virtual actions express something immoral in their performance but are not immoral by themselves. Consequentialists, (...) on the other hand, claim that the immorality of virtual actions arises from their harmful consequences. I argue that both approaches have serious difficulties meeting the moral challenge posed by the Gamer’s Dilemma. They tend to confuse the morality of in-game actions either with the morality of their real-world counterparts or with the morality of games as objects. Following this critical analysis, I will develop a Kantian argument and defend it against two objections. So far, deontological responses to the Gamer’s Dilemma have been sought in vain. Yet, with Kant, its moral challenge can be met by looking at the gamer’s reasons. From this perspective, the Gamer’s Dilemma is based on a false assumption: the moral status of gaming acts does not derive from a normative equation with their real-world counterparts but only from their justifications.

In response to the spread of COVID-19, governments across the world have, with very few exceptions, enacted sweeping restrictive lockdown policies that impede citizens’ freedom to move, work, and assemble. This paper critically responds to the central arguments for restrictive lockdown legislation. We build our critique on the following assumption: public policy that enjoys virtually unanimous support worldwide should be justified by uncontroversial moral principles. We argue that that the virtually unanimous support in favor of restrictive lockdowns is not adequately (...) justified by the arguments given in favor of them. Importantly, this is not to say that states ought not impose restrictive lockdown measures, but rather that the extent of the acceptance of these measures is not proportionate to the strength of the arguments for lockdowns. -/- We begin by exploring the case for restrictive lockdowns. We first argue that several of the principles that are used to justify the lockdowns yield unexpectedly revisionary implications for other political problems that many would be unwilling to accept. We then outline what we consider the strongest argument for a lockdown—namely, that its net welfare benefits are great enough to defeat the moral presumption against restricting citizens’ civil liberties to move, work, and assemble. However, we give a number of reasons for doubting that the lockdown’s net welfare benefits are, in fact, sufficiently high to defeat the presumption against it. (shrink)

The conventional wisdom regarding the aims and shortcomings of Kantian constructivism is mistaken. The aim of metaethical constructivism is not to provide a naturalistic account of the objectivity of normative facts by deriving substantive morality from a conception of agency so thin as to be uncontroversial (a task at which it is generally regarded to have failed). Its aim is to explain the “grip” that normative facts have on us—to avoid what I call the problem of normative alienation. So understood, (...) Kantian constructivism faces two problems: that determinate normative facts cannot be derived from agency and that its individualistic conception of agency cannot account for the sociality of morality. I propose and elaborate a social conception of agency that is better able to address the latter problem while still avoiding normative alienation, and evaluate two different strategies for responding to the former problem.

The Generality Problem is widely recognized to be a serious problem for reliabilist theories of justification. James R. Beebe's Statistical Solution is one of only a handful of attempted solutions that has garnered serious attention in the literature. In their recent response to Beebe, Julien Dutant and Erik J. Olsson successfully refute Beebe's Statistical Solution. This paper presents a New Statistical Solution that countenances Dutant and Olsson's objections, dodges the serious problems that trouble rival solutions, and retains the theoretical virtues (...) that made Beebe's solution so attractive in the first place. There indeed exists a principled, rigorous, conceptually sparse, and plausible solution to the Generality Problem: it is the New Statistical Solution. (shrink)

The verb ‘to know’ can be used both in ascriptions of propositional knowledge and ascriptions of knowledge of acquaintance. In the formal epistemology literature, the former use of ‘know’ has attracted considerable attention, while the latter is typically regarded as derivative. This attitude may be unsatisfactory for those philosophers who, like Russell, are not willing to think of knowledge of acquaintance as a subsidiary or dependent kind of knowledge. In this paper we outline a logic of knowledge of acquaintance in (...) which ascriptions like ‘Mary knows Smith’ are regarded as formally interesting in their own right, remaining neutral on their relation to ascriptions of propositional knowledge. The resulting logical framework, which is based on Hintikka’s modal approach to epistemic logic, provides a fresh perspective on various issues and notions at play in the philosophical debate on acquaintance.

Copernican reasoning involves considering ourselves, in the absence of other information, to be randomly selected members of a reference class. Consider the reference class intelligent observers. If there are extraterrestrial intelligences (ETIs), taking ourselves to be randomly selected intelligent observers leads to the conclusion that it is likely the Earth has a larger population size than the typical planet inhabited by intelligent life, for the same reason that a randomly selected human is likely to come from a more populous country. (...) The astrophysicist Fergus Simpson contends that this reasoning supports the claims that the typical planet inhabited by ETIs is smaller than Earth (radius about 5,000km; cf. Earth's radius = 6,371km) and that the typical ETI is significantly larger than us about 314kg, the size of an adult male grizzly bear). Simpson's applications of Copernican reasoning are novel and exciting. They should be of interest to philosophers concerned with Richard Gott's delta t argument, the N=1 problem in astrobiology, limited principles of indifference, and probabilistic epistemology in general. While we agree with Simpson about the qualitative direction of his conclusions, we take issue with his presentation of precise quantitative results because his methods (1) display bias, (2) ignore other variables contributing to population size, (3) commit an equivocation, and (4) conceal their dependence on arbitrary assumptions.

Iris Murdoch’s The Sovereignty of Good—especially the first essay, “The Idea of Perfection”—is often associated with a critique of a certain picture of agency and its proper place in ethical thought. There is implicit in this critique, however, an alternative, much richer one. I propose a reading of Murdochian agency in terms of the continuous activity of cultivating and refining a distinctive practical standpoint, and I apply this reading to her account of moral progress. For Murdoch moral progress depends on (...) transcending egoism and achieving clear perception of a normatively-saturated reality, but it would be a mistake to think of egoism in terms of selfishness, or clarity in terms of altruism. Rather, I argue, Murdochian moral progress requires overcoming socially-conditioned and often ideological forms of alienation, and making the social conditions that inform our practical standpoints self-conscious.

Samuel Buchoul, dans « Homo Scribens : vers une bio-graphie qui ne recherche plus rien », cherche à articuler écriture et vie en se demandant pourquoi la vie écrit-elle. Dès lors que les concepts de biographie et de biologie s’entrelacent tout au long de La vie la mort, Buchoul interroge le concept derridien d’écriture à travers l’étude croisée de Jacob, Heidegger, Nietzsche et Freud, et le relit à la lumière de quelques arguments de Jean-Paul Sartre et de Bernard Stiegler.

Scholars have often thought that a monistic reading of Aristotle’s definition of the human good – in particular, one on which “best and most teleios virtue” refers to theoretical wisdom – cannot follow from the premises of the ergon argument. I explain how a monistic reading can follow from the premises, and I argue that this interpretation gives the correct rationale for Aristotle’s definition. I then explain that even though the best and most teleios virtue must be a single virtue, (...) that virtue could in principle be a whole virtue that arises from the combination of all the others. I also clarify that the definition of the human good aims at capturing the nature of human eudaimonia only in its primary case. (shrink)

In Bencivenga’s “Consequences in Kantian Ethics,” he offers a version of Kant’s ethics according to which the most rational approach to living one’s life is “to always imagine what might follow from one’s moves and to choose moves accordingly” (284), but according to which agents always nevertheless must be modest in their judgments about what they ought to do because the actual consequences of their actions might not turn out as they imagined. In this way, he tries to foreground the (...) role of consequences in Kant's ethics. In this paper, I argue against Bencivenga and, in particular, against the idea that according to Kant, to determine whether an agent’s action is good we must wait for its consequences to unfold in time.

In recent years, the number of studies examining mind wandering has increased considerably, and research on the topic has spread widely across various domains of psychological research. Although the term “mind wandering” has been used to refer to various cognitive states, researchers typically operationalize mind wandering in terms of “task-unrelated thought” (TUT). Research on TUT has shed light on the various task features that require people’s attention, and on the consequences of task inattention. Important methodological and conceptual complications do persist, (...) however, in current investigations of TUT. As we argue, these complications may be dampening the development of a more nuanced scientific account of TUT. Here, we outline three of the more prominent methodological and conceptual complications in the literature on TUT, and we discuss potential directions for researchers to take as they move forward in their investigations of TUT.

Loyalty is considered central to people’s moral life, yet little is known about how people think about what it means to be loyal. We used a prototype approach to understand how loyalty is represented in Colombia and the United States and how these representations mediate attributions of loyalty and moral judgments of loyalty violations. Across 7 studies (N = 1,984), we found cross-cultural similarities in the associative meaning of loyalty (Study 1) but found differences in the centrality of features associated (...) with loyalty (Study 2) and the latent structure of loyalty representations (Study 3). Colombians represent loyalty in terms of more general moral characteristics, while US participants represent loyalty in terms of interpersonal commitment, both in contrast with current approaches to loyalty. By comparing representations of loyalty and honesty, we establish that difference in loyalty conceptualizations reflect a different way of thinking about loyalty rather than morality more generally (Study 4). Further, Colombians attributed greater loyalty to individuals with general moral characteristics compared to participants from the United States sample (Study 5) and were more likely to classify non-loyal values as loyalty-related (Study 6). While the centrality of prototypical features predicts categorizing norm violations as loyalty-related, differences in prototypical structure account for differences in the severity of moral judgment for such violations (Study 7), which suggests that loyalty representations have similar functions even though these representations differ in structural characteristics.

In this paper I defend the traditional interpretations of Kant’s Formula of a Law of Nature from recent attacks leveled by Faviola Rivera-Castro, James Furner, Ido Geiger, Pauline Kleingeld and Sven Nyholm. After a short introduction, the paper is divided into four main sections. In the first, I set out the basics of the three traditional interpretations, the Logical Contradiction Interpretation, the Practical Contradiction Interpretation and the Teleological Contradiction Interpretation. In the second, I examine the work of Geiger, Kleingeld and (...) Nyholm: these three commentators reject the traditional interpretations entirely, but I argue that this rejection is ill-founded. In the third and fourth, I take a detailed look at Furner’s work, work in which he seeks to revise (rather than reject) the traditional interpretations. I argue that, despite his more modest aims, Furner’s revision is also ill-founded. (shrink)

Confabulation is typically understood to be dysfunctional. But this understanding neglects the phenomenon’s potential benefits. In fact, we think that the benefits of non-clinical confabulation provide a better foundation for a general account of confabulation. In this paper, we start from these benefits to develop a social teleological account of confabulation. Central to our account is the idea that confabulation manifests a kind of willful ignorance. By understanding confabulation in this way, we can provide principled explanations for the difference between (...) clinical and non-clinical cases of confabulation and the extent to which confabulation is rational.

There is an old meta-philosophical worry: very roughly, metaphysical theories have no observational consequences and so the study of metaphysics has no value. The worry has been around in some form since the rise of logical positivism in the early twentieth century but has seen a bit of a renaissance recently. In this paper, I provide an apology for metaphysics in the face of this kind of concern. The core of the argument is this: pure mathematics detaches from science in (...) much the same manner as metaphysics and yet it is valuable nonetheless. The source of value enjoyed by pure mathematics extends to metaphysics as well. Accordingly, if one denies that metaphysics has value, then one is forced to deny that pure mathematics has value. The argument places an added burden on the sceptic of metaphysics. If one truly believes that metaphysics is worthless (as some philosophers do), then one must give up on pure mathematics as well.

In this paper I provide a novel argument for scientific realism. In contrast to most recent defenses of SR, my defense of SR does not rely on the no-miracles argument. Instead, I take a more unconventional approach: I focus on the different kinds of justification available to different individuals in relation to different kinds of propositions. I maintain that this alternative focus shows that most people are warranted in believing many propositions about unobservables. The paper is divided into three main (...) sections. In the first, I rehearse the main moves in the recent debate about SR. In the second, I argue that the discussion in section one enables us to see that most of the arguments in the recent debate about SR mistake their target: instead of being about SR, they are about meta-SR. I argue that what I call the JJ-principle should be rejected and, further, that if the JJ-principle is rejected, then meta-SR may be cleaved from SR. This enables me to advance to a position I call thin realism in the third and final section of the paper. (shrink)

We present a game mechanic called pseudo-visibility for games inhabited by non-player characters (NPCs) driven by reinforcement learning (RL). NPCs are incentivized to pretend they cannot see pseudo-visible players: the training environment simulates an NPC to determine how the NPC would act if the pseudo-visible player were invisible, and penalizes the NPC for acting differently. NPCs are thereby trained to selectively ignore pseudo-visible players, except when they judge that the reaction penalty is an acceptable tradeoff (e.g., a guard might accept (...) the penalty in order to protect a treasure because losing the treasure would hurt even more). We describe an RL agent transformation which allows RL agents that would not otherwise do so to perform some limited self-reflection to learn the training environments in question. (shrink)

Jennifer Saul argues that the evidence from the literature on implicit biases entails a form of skepticism. In this paper, I argue that Saul faces a dilemma: her argument is either self-defeating, or it does not yield a skeptical conclusion. For Saul, both results are unacceptable; thus, her argument fails.

Matthew Leisinger (2020) argues that previous interpretations of John Locke’s account of akrasia (or weakness of will) are mistaken and offers a new interpretation in their place. In this essay, we aim to recapitulate part of this debate, defend a previously articulated interpretation by responding to Leisinger’s criticisms of it, and explain why Leisinger’s own interpretation faces textual and philosophical problems that are serious enough to disqualify it as an accurate reconstruction of Locke’s views. In so doing, we aim to (...) shed further light on Locke’s views on the various ways in which humans are prone to err in their pursuit of happiness. (shrink)

This paper articulates a functionalist account of intra-party democracy (IPD). Like realist critics, we insist that IPD practices be evaluated on the basis of whether they facilitate resistance to domination and capture at the level of the polity as a whole, and therefore accept certain realist worries about IPD. Yet realists neglect the possibility that wealthy interests could control the political agenda by capturing all viable parties simultaneously-and that mass-facing IPD could counter this threat of oligarchic agenda capture. Taking this (...) as the key function of IPD within broader democratic systems, we conclude that inclusionary party reform is less urgent in more flexible party systems, where dissenters are better able to resist this threat from within the framework of inter-party competition. Regardless of the context, meanwhile, we also conclude that mass-facing IPD practices should aim at enabling ordinary members and supporters of a party to resist agenda capture by oligarchic interests. Though we stop short of defending any particular set of reforms, we reject the emphasis of recent IPD advocates on individualized forms of deliberative participation, in favor of a more oppositional and collectively-oriented approach-on the grounds that the latter is more likely to encourage the development of effective institutions of countervailing power.

Samuel Kerstein’s recent (2013) How To Treat Persons is an ambitious attempt to develop a new, broadly Kantian account of what it is to treat others as mere means and what it means to act in accordance with others’ dignity. His project is explicitly nonfoundationalist: his interpretation stands or falls on its ability to accommodate our pretheoretic intuitions, and he does an admirable job of handling carefully a range of well fleshed out and sometimes subtle examples. In what follows, (...) I shall give a quick summary of the chapters and then say two good things about the book and one critical thing. (shrink)

The idea that time does not exist is, for many, unthinkable: time must exist. Almost every experience we have tells us so. There has been plenty of debate around what time is like, but not whether it exists. The goal of this book is to make the absence of time thinkable. Time might not exist. Beginning with an empirically flavoured examination of the 'folk' concept of time, the book explores the implications this has for our understanding of agency, and the (...) extent to which our best physics and best metaphysics are compatible with a timeless conception of reality.

In recent years, some have claimed that a Darwinian perspective will revolutionize the study of human society and culture. This project is viewed with disdain and suspicion, on the other hand, by many practicing social scientists. This article seeks to clear the air in this heated debate by dissociating two claims that are too often assumed to be inseparable. The first is the ‘ontological’ claim that Darwinian principles apply, at some level of abstraction, to human society and culture. The second (...) is the more ‘pragmatic’ claim that this observation necessitates substantial changes in the practices of social scientists. Even if some version of the first claim is true, I argue – which I believe is quite likely – the second does not follow. This observation ought to chasten the most overzealous advocates of Darwinian social science, as well as softening the instinctive resistance of many social scientists and historians to the genuine insights enabled by a Darwinian approach. The conclusion discusses these insights, the most important of which is a methodological prescription for normative theory. (shrink)

The third deduction in Plato’s Parmenides is often given a constructive reading on which Plato’s Parmenides, or even Plato himself, presents us with a positive account of the relation between parts and wholes. However, I argue that there is a hitch in the third deduction which threatens to undermine the mereology of the third deduction by the lights of the dialogue. Roughly, even if the Others partake of the One, the account of the third deduction leads to an ontology of (...) gunk, that is, an ontology on which there are no mereological atoms (except for the One). Hence, it is unclear whether the participation relation between the Others and the One is sufficient to impose the sort of structure on the Others which, in the context of this deduction, Parmenides (or Plato) seems to hope for. Instead of the constructive reading of the third deduction, I therefore offer an aporetic reading on which the third deduction raises further difficulties for the participation relation at the heart of young Socrates’ theory of Forms.

Contemporary critics of the administrative state are right to highlight the dangers of vesting too much power in a centralized bureaucracy removed from popular oversight and accountability. Too often neglected in this literature, however, are the dangers of vesting too little power in a centralized state, which enables dominant groups to further expand their social and economic advantages through decentralized means. This article seeks to synthesize these concerns, understanding them as reflecting the same underlying danger of state capture. It then (...) articulates a set of heuristics for the design of public and administrative institutions, which aim at minimizing the risks of capture from both public and private sources. By following these heuristics, it claims, we can successfully employ the administrative state as a weapon against concentrated private power, rather than allowing it to serve as a tool of dominant groups.

In this discussion note, I aim to reconstruct and assess Korsgaard's recent attempt to extend her regress argument. I begin, in section 1, with a brief recapitulation of the regress argument. Then, in section 2, I turn to the extension.

According to Kantian moral religion, because there is a duty to promote the highest good, we are warranted in believing in God and immortality. However, this article shows that the duty to promote the highest good is incoherent, and that popular conceptualizations of the highest good cannot avoid this incoherence. After arguing, additionally, against attempts to ground Kantian moral religion on the highest good in some role other than the object of duty, it is shown that Kant seems to have (...) been aware of the original problem, suggesting an explanation for why he abandoned the highest good around 1800.

I argue in this paper that Immanuel Kant's account of the moral wrongness of contempt in the Metaphysics of Morals provides important resources for our understanding of the nature of moral subjectivity. Although Kant typically emphasizes the subject's position as autonomous addressor of the moral law, his remarks on contempt bring into relief a dynamic relationship at the heart of practical subjectivity between the addressor and addressee positions. After tracing the development of reflection concerning the addressor and addressee positions in (...) early modern philosophy, beginning with Francisco Suarez and Samuel Pufendorf, I articulate and defend what I take to be a Kantian conception of the relation between those positions. More specifically, I argue that to be a moral subject at all is necessarily to position oneself as the addressor of the moral law, but that one must at the same time maintain oneself in the addressee position, resisting the full conversion to the addressor position that autonomy seems to demand.

Traditionally, logic has been the dominant formal method within philosophy. Are logical methods still dominant today, or have the types of formal methods used in philosophy changed in recent times? To address this question, we coded a sample of philosophy papers from the late 2000s and from the late 2010s for the formal methods they used. The results indicate that the proportion of papers using logical methods remained more or less constant over that time period but the proportion of papers (...) using probabilistic methods was approximately three times higher in the late 2010s than it was in the late 2000s. Further analyses explored this change by looking more closely at specific methods, specific levels of technical engagement, and specific subdisciplines within philosophy. These analyses indicate that the increasing proportion of papers using probabilistic methods was pervasive, not confined to particular probabilistic methods, levels of sophistication, or subdisciplines.

This article challenges the association between realist methodology and ideals of legitimacy. Many who seek a more “realistic” or “political” approach to political theory replace the familiar orientation towards a state of justice with a structurally similar orientation towards a state of legitimacy. As a result, they fail to provide more reliable practical guidance, and wrongly displace radical demands. Rather than orienting action towards any state of affairs, I suggest that a more practically useful approach to political theory would directly (...) address judgments, by comparing the concrete possibilities for action faced by real political actors.

In the Laws, Plato argues that the legislator should attempt to persuade people to voluntarily obey the laws. This persuasion is accomplished through use of legislative preludes. Preludes (also called preambles) are short arguments written into the legal code, which precede laws and give reasons to follow them. In this paper, I argue that Plato’s use of persuasive preludes shows that he endorses the core features of a public reason theory of political justification. Many philosophers argue that Plato’s political philosophy (...) is deeply at odds with contemporary liberal political philosophy. While Plato certainly does not affirm (and even rejects) some of the main features of liberalism, if it could be shown that he endorses some account of public reason (which is a liberal idea to its core), this would suggest that there is more in common between Plato and liberalism than many philosophers think. Furthermore, if combined with the work of philosophers, like C.C.W. Taylor, this could form a cumulative case against those who argue that there is little in common between Plato’s political philosophy and liberalism. In short, by showing that Plato endorses the core features of public reason, I endeavor to show that there is more in common between Plato and liberalism than is often thought. (shrink)

Jaakko Hintikka proposed treating objectual perception sentences, such as “Alice sees Bob,” as de re propositional perception sentences. Esa Saarinen extended Hintikka’s idea to eventive perception sentences, such as “Alice sees Bob smile.” These approaches, elegant as they may be, are not philosophically neutral, for they presuppose, controversially, that the content of all perceptual experiences is propositional in nature. The aim of this paper is to propose a formal treatment of objectual and eventive perception sentences that builds on Hintikka’s modal (...) approach to propositional attitude ascriptions while avoiding controversial assumptions on the nature of perceptual experiences. Despite being simple and theoretically frugal, our approach is powerful enough to express a variety of interesting philosophical views about propositional, objectual, and eventive perception sentences, thus enabling the study of their inferential relationships.

Do we live in a computer simulation? I will present an argument that the results of a certain experiment constitute empirical evidence that we do not live in, at least, one type of simulation. The type of simulation ruled out is very specific. Perhaps that is the price one must pay to make any kind of Popperian progress.

The third Meditation is typically understood to contain two a posteriori arguments for the existence of God. The author focuses on the second argument, where Descartes proves the existence of God partly in virtue of proving that Descartes cannot be the cause of himself. To establish this, Descartes argues that if he were the cause of himself, then he would endow himself with any conceivable perfection. The justification for this claim is that bringing about a substance is more difficult than (...) creating an attribute, so anything that can do the former can do the latter. While current explanations of this justification are either implausible or inadequate, the author argues that this principle derives support from a scholastic distinction between being-as-such and determinate being. With this distinction in view, we can make sense of Descartes's argument without appealing to ambiguous or inadequate notions. (shrink)

Philosophical work in the ethics of thought focuses heavily on the ethics of belief, with, in recent years, a particular emphasis on the ways in which we might wrong other people either through our beliefs about them, or our failure to believe what they tell us. Yet in our own lives we often want not merely to be believed, but rather to be understood by others. What does it take to understand another person? In this paper, I provide an account (...) of interpersonal understanding that speaks to this widespread human desire to be understood by others. On the view I defend, to be understood by another person is for them to see our motivating reasons as justifying reasons, whether or not they actually take our reasons to have that normative force. I then provide an explanation of why such understanding is valuable in our lives, which emphasizes how being understood by another person is a way of being more fully with them. (shrink)

We sometimes fail unwittingly to do things that we ought to do. And we are, from time to time, culpable for these unwitting omissions. We provide an outline of a theory of responsibility for unwitting omissions. We emphasize two distinctive ideas: (i) many unwitting omissions can be understood as failures of appropriate vigilance, and; (ii) the sort of self-control implicated in these failures of appropriate vigilance is valuable. We argue that the norms that govern vigilance and the value of self-control (...) explain culpability for unwitting omissions. (shrink)

In this paper I intend to raise a problem for so-called Frankfurt examples. I begin by describing the examples and what they are used for. Then I describe the problem.

In recent years evolutionary psychologists have developed and defended the Massive Modularity Hypothesis, which maintains that our cognitive architecture—including the part that subserves ‘central processing’ —is largely or perhaps even entirely composed of innate, domain-specific computational mechanisms or ‘modules’. In this paper I argue for two claims. First, I show that the two main arguments that evolutionary psychologists have offered for this general architectural thesis fail to provide us with any reason to prefer it to a competing picture of the (...) mind which I call the Library Model of Cognition. Second, I argue that this alternative model is compatible with the central theoretical and methodological commitments of evolutionary psychology. Thus I argue that, at present, the endorsement of the Massive Modularity Hypothesis by evolutionary psychologists is both unwarranted and unmotivated. (shrink)

In this paper I argue that constructivism in mathematics faces a dilemma. In particular, I maintain that constructivism is unable to explain (i) the application of mathematics to nature and (ii) the intersubjectivity of mathematics unless (iii) it is conjoined with two theses that reduce it to a form of mathematical Platonism. The paper is divided into five sections. In the first section of the paper, I explain the difference between mathematical constructivism and mathematical Platonism and I outline my argument. (...) In the second, I argue that the best explanation of how mathematics applies to nature for a constructivist is a thesis I call Copernicanism. In the third, I argue that the best explanation of how mathematics can be intersubjective for a constructivist is a thesis I call Ideality. In the fourth, I argue that once constructivism is conjoined with these two theses, it collapses into a form of mathematical Platonism. In the fifth, I confront some objections. (shrink)
