I am writing on moral knowledge in Locke's Essay Concerning Human Understanding. There are two basic parts. In the first part, I articulate and attack a predominant interpretation of the Essay . This interpretation attributes to Locke the view that he did not write in the Essay anything that would be inconsistent with his early views in the Questions Concerning the Laws of Nature that there exists a single, ultimate, moral standard, i.e., the Law of Nature. For example, John Colman, (...) in his book John Locke's Moral Philosophy , argues that even though Locke explains in the Essay that we arbitrarily create our moral notions, they are still objective since they are bound together with the Law of Nature. Colman explains that the features of human nature relevant to the derivation of the Law of Nature are universally shared needs and concerns . I argue that this presupposes a view of Locke which assumes that there are essences of species independent of our beliefs about them. However, I attempt to show from the text of the Essay that this view cannot be supported. ;In the second part, I argue that the text of the Essay supports two alternative theses. The first is that given the kind of metaphysical world-view presupposed by the corpuscular method of science employed within the Essay, coupled with Locke's commitment to the possibility of moral knowledge, he was left with only one option with reference to ethics, viz., to make moral goodness or evil a mind-dependent relation between a rule and an action, instead of a property of an action or person which exists independently of our moral beliefs. This view is logically inconsistent with the existence of the Law of Nature. The second is that Locke has a semantical view of moral claims which is consistent with his relational view of moral goodness, viz., the primary function of moral judgments is to recommend behavior for ourselves and others. I described. However, Locke explains in the Essay that the opposite takes place with respect to our moral notions: events and persons must conform to the moral notion. ;On the account that I offer, Locke's views on moral epistemology are much closer to David Hume's than many have supposed, and correspondingly, anticipate the more skeptical views of moral epistemology in the twentieth century.

Intertheoretic reduction in physics aspires to be both to be explanatory and perfectly general: it endeavors to explain why an older, simpler theory continues to be as successful as it is in terms of a newer, more sophisticated theory, and it aims to relate or otherwise account for as many features of the two theories as possible. Despite often being introduced as straightforward cases of intertheoretic reduction, candidate accounts of the reduction of general relativity to Newtonian gravitation have either been (...) insufficiently general or rigorous, or have not clearly been able to explain the empirical success of Newtonian gravitation. Building on work by Ehlers and others, I propose a different account of the reduction relation that is perfectly general and meets the explanatory demand one would make of it. In doing so, I highlight the role that a topology on the collection of all spacetimes plays in defining the relation, and how the selection of the topology corresponds with broader or narrower classes of observables that one demands be well-approximated in the limit.

Metaphysics-first approaches dominate the current literature in the epistemology of modality. According to metaphysics-firsters, metaphysical theses have an important role in the justification of modal epistemologies. For example, the thesis that essentialist truths constitute the metaphysical grounds of modal truths is meant to have an important role in the justification of essentialist modal epistemologies. In this article, we argue against this approach. We first pick up some of the groundwork on behalf of the metaphysics-firsters and explicitly spell out potential arguments (...) for their view. However, despite some initial plausibility, these arguments are ultimately found wanting. We conclude that the metaphysics-first approach lacks motivation and puts far too stringent demands upon modal epistemologists. (shrink)

Descartes is widely portrayed as the arch proponent of “the epistemological transparency of thought” (or simply, “Transparency”). The most promising version of this view—Transparency-through-Introspection—says that introspecting (i.e., inwardly attending to) a thought guarantees certain knowledge of that thought. But Descartes rejects this view and provides numerous counterexamples to it. I argue that, instead, Descartes’s theory of self-knowledge is just an application of his general theory of knowledge. According to his general theory, certain knowledge is acquired only through clear and distinct (...) intellection. Thus, in his view, certain knowledge of one’s thoughts is acquired only through clear and distinct intellection of one’s thoughts. Introspection is a form of intellection and it can be clear and distinct. Ordinarily, however, introspection isn’t clear and distinct but is instead confused with dubitable perceptions of bodies. To make introspection clear and distinct, we need to “sharply separate” it from all perceptions of bodies by doubting all perceptions of bodies. Without such radical doubt, introspection remains confused and we lack certain knowledge not just of the specific features of our thoughts, but even of the minimal claim that a thought exists. Far from being the high priest of Transparency, Descartes is radically opposed to it. (shrink)

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.

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)

In “History of the Lie: Prolegomena,” Derrida criticizes Arendt’s commitment to the “great resiliency” of factual truth against all lies in her essay “Truth and Politics,” claiming that she reintroduces a teleological account of history that clashes with her anti-totalitarian and anti-systematic thinking. By focussing on her understanding of truth-telling as action, this article shows that Arendt does not turn truth into a permanently stable ground for politics. Instead, Arendt’s theory of self-deception constitutes a lie capable of ending all truth. (...) Set in opposition to the nihilism of self-deception, Arendt understands truth-telling as an exemplary act that preserves the possibility of truthfulness and future actions. (shrink)

We normally take it for granted that other people will live on after we ourselves have died. Even if we do not believe in a personal afterlife in which we survive our own deaths, we assume that there will be a "collective afterlife" in which humanity survives long after we are gone. Samuel Scheffler maintains that this assumption plays a surprising - indeed astonishing - role in our lives.

The ethics of citation has attracted increased attention in recent discussions of research and publication ethics, fraud and plagiarism. Little attempt has been made, however, to situate specific citation misbehaviors in terms of broader ethical practices and principles. To investigate researchers’ perceptions of citation norms, we surveyed active US researchers receiving federal funding from the National Institutes of Health (NIH), the National Science Foundation (NSF), and the National Endowment for the Humanities (NEH). Participants (_n_ = 257) were asked about citation (...) norms they endorse (norm reports), the behaviors they perceive others to engage in (peer reports), and their own citation behaviors (self-reports). Our analyses showed that while considerable discrepancies exist between norm reports, peer reports and self-reports, respondents’ discipline has no significant effect on these. Participants indicated that their own practices and that of their peers falls short of the norms they endorse, but that their own behavior is much less ethically deficient than that of their peers. An exploratory factor analysis revealed that ethically questionable citation behaviors could be grouped usefully into three categories: strategic citations, neglectful citations, and blind citations. Contrary to our hypothesis, the survey showed that greater experience does not always result in better citation practices. A particularly divisive issue pertained to intentionally citing authors from underrepresented demographic groups for reasons of social justice, but broad support for this practice is lacking, although arts and humanities scholars are slightly more supportive. Most researchers view questionable citation practices as negatively affecting their disciplines. Our findings suggest the need for clearer articulations of the citation norms and improved guidance and training about citations. (shrink)

The new edition of this introductory text presents, in an accessible way, classical and contemporary readings on topics central to and representative of all major periods of the Western philosophical tradition. The book presents 55 readings (23 of which are new to the fourth edition) on seven topics: epistemology, philosophy of religion, metaphysics, personal identity and immortality, free will and determinism, ethics, and political and social philosophy. Pedagogical features make these readings accessible and interesting to beginning students. All the introductions (...) and biographical sketches have been revised for the fourth edition, as have the study questions and glossary. The explanatory footnotes and the stylistic modernization of texts are new to the fourth edition. (shrink)

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.

Gils-Schmidt and Salloch recognise that human and climate health are inextricably linked, and that mitigating healthcare-associated climate harms is essential for protecting human health.1 They argue that physicians have a duty to consider how their own practices contribute to climate change, including during their interactions with patients. Acknowledging the potential for conflicts between this duty and the provision of individual patient care, they propose the application of Korsgaard’s neo-Kantian account of practical identities to help navigate such scenarios. In this commentary, (...) we argue that by focusing attention on this physician–patient level, the authors overlook the complexity of climate change, both within the healthcare sector and beyond. We recognise the importance of individual agency in tackling this issue, and we also recognise that the authors do briefly acknowledge the importance of considering these broader complexities; however, we emphasise the need for climate and health discussions/action to be situated in a wider framework of systemic change. Our concern is that overemphasis on patient-level interactions risks normalising the prioritisation of individual-level approaches to addressing climate change, detracting from such a broader approach. Physician training emphasises the need for trust, confidentiality and shared decision-making in the doctor–patient relationship. …. (shrink)

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)

Emotions and moods have been distinguished in the literature. If they are distinct, we may expect emotion regulation and mood regulation to be distinct too. We show that although emotion regulation and mood regulation are considered theoretically distinct, they are often confounded empirically. We review characteristics proposed to distinguish emotions from moods by different theoretical approaches to emotion. We also review challenges to these propositions, suggesting that one valid distinction involves intentionality. Building on the above, we discuss possible differences between (...) emotion regulation and mood regulation. Finally, we encourage the use of accurate terminology, argue for the importance of empirically testing hypotheses regarding distinctions between emotion regulation and mood regulation, and discuss possible implications.

Can an AGI create a more intelligent AGI? Under idealized assumptions, for a certain theoretical type of intelligence, our answer is: “Not without outside help”. This is a paper on the mathematical structure of AGI populations when parent AGIs create child AGIs. We argue that such populations satisfy a certain biological law. Motivated by observations of sexual reproduction in seemingly-asexual species, the Knight-Darwin Law states that it is impossible for one organism to asexually produce another, which asexually produces another, and (...) so on forever: that any sequence of organisms (each one a child of the previous) must contain occasional multi-parent organisms, or must terminate. By proving that a certain measure (arguably an intelligence measure) decreases when an idealized parent AGI single-handedly creates a child AGI, we argue that a similar Law holds for AGIs. (shrink)

Legg and Hutter, as well as subsequent authors, considered intelligent agents through the lens of interaction with reward-giving environments, attempting to assign numeric intelligence measures to such agents, with the guiding principle that a more intelligent agent should gain higher rewards from environments in some aggregate sense. In this paper, we consider a related question: rather than measure numeric intelligence of one Legg- Hutter agent, how can we compare the relative intelligence of two Legg-Hutter agents? We propose an elegant answer (...) based on the following insight: we can view Legg-Hutter agents as candidates in an election, whose voters are environments, letting each environment vote (via its rewards) which agent (if either) is more intelligent. This leads to an abstract family of comparators simple enough that we can prove some structural theorems about them. It is an open question whether these structural theorems apply to more practical intelligence measures. (shrink)

We define a notion of the intelligence level of an idealized mechanical knowing agent. This is motivated by efforts within artificial intelligence research to define real-number intelligence levels of compli- cated intelligent systems. Our agents are more idealized, which allows us to define a much simpler measure of intelligence level for them. In short, we define the intelligence level of a mechanical knowing agent to be the supremum of the computable ordinals that have codes the agent knows to be codes (...) of computable ordinals. We prove that if one agent knows certain things about another agent, then the former necessarily has a higher intelligence level than the latter. This allows our intelligence no- tion to serve as a stepping stone to obtain results which, by themselves, are not stated in terms of our intelligence notion (results of potential in- terest even to readers totally skeptical that our notion correctly captures intelligence). As an application, we argue that these results comprise evidence against the possibility of intelligence explosion (that is, the no- tion that sufficiently intelligent machines will eventually be capable of designing even more intelligent machines, which can then design even more intelligent machines, and so on).

According to Aristotle, the medical art aims at health, which is a virtue of the body, and does so in an unlimited way. Consequently, medicine does not determine the extent to which health should be pursued, and “mental health” falls under medicine only via pros hen predication. Because medicine is inherently oriented to its end, it produces health in accordance with its nature and disease contrary to its nature—even when disease is good for the patient. Aristotle’s politician understands that this (...) inherent orientation can be systematically distorted, and so would see the need for something like the Hippocratic Oath. (shrink)

Can an agent's intelligence level be negative? We extend the Legg-Hutter agent-environment framework to include punishments and argue for an affirmative answer to that question. We show that if the background encodings and Universal Turing Machine (UTM) admit certain Kolmogorov complexity symmetries, then the resulting Legg-Hutter intelligence measure is symmetric about the origin. In particular, this implies reward-ignoring agents have Legg-Hutter intelligence 0 according to such UTMs.

Many people have long-term commitments that require coordination and cooperation with others. To achieve this, we construct plans to settle when, how, and for how long to pursue certain goals rather than others. This raises an interesting cognitive problem, namely that individuals can, at any given moment, manage significantly less information than they will need to accomplish their goals. Call this the Problem of Scarce Information. The solution requires a special self-regulatory system that strategically manages the varying informational demands of (...) one's activity. This paper argues that vigilance has structural and functional characteristics that make it apt to play this role. This paper illuminates both crucial aspects of temporally extended agency, but also the unique practical norms that structure how we act over time. (shrink)

I provide an analysis of sentences of the form ‘To be F is to be G’ in terms of exact truth-maker semantics—an approach that identifies the meanings of sentences with the states of the world directly responsible for their truth-values. Roughly, I argue that these sentences hold just in case that which makes something F is that which makes it G. This approach is hyperintensional, and possesses desirable logical and modal features. These sentences are reflexive, transitive and symmetric, and, if (...) they are true, then they are necessarily true, and it is necessary that all and only Fs are Gs. I close by defining an asymmetric and irreflexive notion of analysis in terms of the reflexive and symmetric one. (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)

Liberalism and Distributive Justice discusses liberalism, capitalism, distributive justice, and John Rawls's difference principle.

After generalizing the Archimedean property of real numbers in such a way as to make it adaptable to non-numeric structures, we demonstrate that the real numbers cannot be used to accurately measure non-Archimedean structures. We argue that, since an agent with Artificial General Intelligence (AGI) should have no problem engaging in tasks that inherently involve non-Archimedean rewards, and since traditional reinforcement learning rewards are real numbers, therefore traditional reinforcement learning probably will not lead to AGI. We indicate two possible ways (...) traditional reinforcement learning could be altered to remove this roadblock. (shrink)

Most democratic theorists agree that concentrations of wealth and power tend to distort the functioning of democracy and ought to be countered wherever possible. Deliberative democrats are no exception: though not its only potential value, the capacity of deliberation to ‘neutralise power’ is often regarded as ‘fundamental’ to deliberative theory. Power may be neutralised, according to many deliberative democrats, if citizens can be induced to commit more fully to the deliberative resolution of common problems. If they do, they will be (...) unable to get away with inconsistencies and bad or private reasons, thereby mitigating the illegitimate influence of power. I argue, however, that the means by which power inflects political disagreement is far more subtle than this model suggests and cannot be countered so simply. As a wealth of recent research in political psychology demonstrates, human beings persistently exhibit ‘motivated reasoning’, meaning that even when we are sincerely committed to the deliberative resolution of common problems, and even when we are exposed to the same reasons and evidence, we still disagree strongly about what ‘fair cooperation’ entails. Motivated reasoning can be counteracted, but only under exceptional circumstances such as those that enable modern science, which cannot be reliably replicated in our society at large. My analysis suggests that in democratic politics – which rules out the kind of anti-democratic practices available to scientists – we should not expect deliberation to reliably neutralise power.

Master Sorai's Responsals was to eighteenth-century Japan what The Prince was to Renaissance Italy. Like Machiavelli, Ogyu Sorai was a humanist scholar who served a prince and drew on his experiences as a house philosopher and on his vast knowledge of history and political affairs in his work. In 1720, when he began to write the letters that comprise this text, the Tokugawa regime was more than a hundred years old and beset with grave administrative and fiscal problems, about which (...) Sorai had much to say.Samuel Yamashita's impressive translation of this work offers modern readers a rare glimpse of the prevailing political discourse of the day and the specific concepts that rulers had at their disposal as they struggled to manage their domains, find talented men for their bureaucracies, create new sources of revenue, and keep their subjects well fed and happy.Sorai himself, of course, is a presence in the text. He is by tunes earnest, frank, impatient, utterly confident, and occasionally condescending. Unlike his Renaissance counterpart, he is something of an optimist: he was convinced that the introduction of archaic Chinese culture and institutions to Japan would solve its myriad problems.Well-versed in Chinese history, philosophy, religion, medicine, and belles lettres, Sorai holds forth on everything from archaic Chinese divination to Sung poetry and prose. He offers advice on how to become a Confucian gentleman, how to learn to read classical Chinese, and which books to read and which to avoid. He even discusses his belief in a sentient, Chinese-style "heaven," a topic not well understood by modern scholars. Long regarded as one of Sorai's best works, Master Sorai's Reponsals bristles with the sharp and clear opinions of the most influential thinker of Tokugawa Japan. (shrink)

In this article, I explicate Kant’s position on the wide right to abortion. That is, I explore the extent to which, according to Kant’s practical philosophy, abortion is punishable, even if it involves an unjust infringement of the right to life. By focusing on the state’s right to punish, rather than the right to life or the onset of personhood, I use Kant to expose a novel range of issues and questions about the legal status of abortion (and criminal punishment (...) more generally). The article is divided into four sections. In the first, I lay the groundwork for Kant’s theory of rights and briefly canvass some of the literature on Kantian approaches to abortion. In the second, I look at Kant’s discussion of equivocal rights. In the third, I turn to Kant’s discussions of capital punishment and suicide. In the fourth, I examine Kant on honor killings, and I use his position on infanticide in order to extrapolate and explain his ideas about the right to punish in the context of abortion. (shrink)

This morning I intended to get out of bed when my alarm went off. Hearing my alarm, I formed the intention to get up now. Yet, for a time, I remained in bed, irrationally lazy. It seems I irrationally failed to execute my intention. Such cases of execution failure pose a challenge for Mentalists about rationality, who believe that facts about rationality supervene on facts about the mind. For, this morning, my mind was in order; it was my action that (...) apparently made me irrational. What, then, should Mentalists say about the phenomenon of execution failure? The phenomenon of execution failure, and the puzzle it raises for Mentalists, have rarely been discussed. This paper addresses the puzzle in two parts. First, it argues that execution failure is a real phenomenon. It is possible for agents to irrationally fail to act on their present-directed intentions. It follows that Mentalists in the philosophy of action must solve the puzzle of explaining what is irrational about cases of execution failure. Second, this paper begins the search for such a solution. It considers six possible resolutions to the puzzle, arguing that none is obviously the most attractive. These resolutions include a requirement of overall conative consistency, an appeal to the norm of intention consistency, a form of Volitionalism, an appeal to factive mental states, and a proposal due to Garrett Cullity, and a novel requirement of proper functioning.

Skepticism in epistemology refers to the supposedly irrational attitude of suspending judgment about all beliefs, particularly those taken for granted. The skeptical attitude presses philosophy to investigate the conditions under which knowledge and justification rather than accidental truths can be arrived at. In the first chapter, we will investigate how to construct a form of radical skepticism known as Pyrrhonian skepticism; we will see how Agrippa's Trilemma builds three ways of skeptical defense to object to three possible conditions in the (...) structuring of epistemic justification. In the second chapter, we will examine infinitism as a possible answer to the trilemma, as well as the conceptual bases that make possible the existence of this possible solution to the skeptical challenge. In the third, the main objection to infinitism known as the finite mind problem will be analyzed. In the fourth chapter, we will look at an alternative formulation of the trilemma, as well as the challenges this approach poses to the anti-skeptical response. (shrink)

Existing approaches to campaign ethics fail to adequately account for the “arms races” incited by competitive incentives in the absence of effective sanctions for destructive behaviors. By recommending scrupulous devotion to unenforceable norms of honesty, these approaches require ethical candidates either to quit or lose. To better understand the complex dilemmas faced by candidates, therefore, we turn first to the tradition of “adversarial ethics,” which aims to enable ethical participants to compete while preventing the most destructive excesses of competition. As (...) we demonstrate, however, elections present even more difficult challenges than other adversarial contexts, because no centralized regulation is available to halt potential arms races. Turning next to recent scholarship on populism and partisanship, we articulate an alternative framework for campaign ethics, which allows candidates greater room to maneuver in their appeals to democratic populations while nevertheless requiring adherence to norms of social and political pluralism.

How can inferences from models to the phenomena they represent be justified when those models represent only imperfectly? Pierre Duhem considered just this problem, arguing that inferences from mathematical models of phenomena to real physical applications must also be demonstrated to be approximately correct when the assumptions of the model are only approximately true. Despite being little discussed among philosophers, this challenge was taken up by mathematicians and physicists both contemporaneous with and subsequent to Duhem, yielding a novel and rich (...) mathematical theory of stability with epistemological consequences.

The leading reductive approaches to shared agency model that phenomenon in terms of complexes of individual intentions, understood as plan-laden commitments. Yet not all agents have such intentions, and non-planning agents such as small children and some non-human animals are clearly capable of sophisticated social interactions. But just how robust are their social capacities? Are non-planning agents capable of shared agency? Existing theories of shared agency have little to say about these important questions. I address this lacuna by developing a (...) reductive account of the social capacities of non-planning agents, which I argue supports the conclusion that they can enjoy shared agency. The resulting discussion offers a fine-grained account of the psychological capacities that can underlie shared agency, and produces a recipe for generating novel hypotheses concerning why some agents do not engage in shared agency.

Many philosophers have thought that our folk, or pre-reflective, view of persistence is one on which objects endure. This assumption not only plays a role in disputes about the nature of persistence itself, but is also put to use in several other areas of metaphysics, including debates about the nature of change and temporal passage. In this paper, we empirically test three broad claims. First, that most people (i.e. most non-philosophers) believe that, and it seems to them as though, objects (...) persist by enduring rather than perduring. Second, that most people have a view of change on which enduring but not perduring objects count as changing. Third, that one reason why the folk represent time as dynamical is because it seems to them, and they believe that, they endure through time. We found no evidence to support these claims. While there are certainly plenty of ‘folk’ endurantists in the population we tested, there are also plenty of ‘folk’ perdurantists. We did not find robust evidence that a majority of people believed that, or it seemed to them as though, objects endure rather than perdure. We conclude that many arguments in favour of endurantism that appeal to folk beliefs about, or experiences of, persisting objects and change rest on views about those beliefs and experiences that are empirically unsupported. There is no evidence to suggest that endurantism is the folk friendly view of persistence, and so we should stop treating it as such without argument. (shrink)

In Nicomachean Ethics 1. 7, Aristotle gives a definition of the human good, and he does so by means of the “ ergon argument.” I clear the way for a new interpretation of this argument by arguing that Aristotle does not think that the ergon of something is always the proper activity of that thing. Though he has a single concept of an ergon, Aristotle identifies the ergon of an X as an activity in some cases but a product in (...) others, depending on the sort of thing the X is—for while the ergon of the eye is seeing, the ergon of a sculptor is a sculpture. This alternative interpretation of Aristotle’s concept of an ergon allows the key explanatory middle term of the ergon argument to be what, I argue, it ought to be: “the best achievement of a human.”.
