Marine ecosystems are under increasing pressure from human activity, yet successful management relies on knowledge. The evidence-based policy (EBP) approach has been promoted on the grounds that it provides greater transparency and consistency by relying on ‘high quality’ information. However, EBP also creates epistemic responsibilities. Decision-making where limited or no empirical evidence exists, such as is often the case in marine systems, creates epistemic obligations for new information acquisition. We argue that philosophical approaches can inform the science-policy interface. Using marine (...) biosecurity examples, we specifically examine the epistemic challenges in the acquisition and acceptance of evidence to inform policy, discussing epistemic due care and biases in consideration of evidence.

Dudgeon, William (1705/6–1743), freethinker and philosopher, is of unknown origins. A tenant farmer who resided at Lennel Hill Farm, near Coldstream, Berwickshire, he was one of several philosophers active in the borders area of Scotland during this period. Other figures in this group include Andrew Baxter, Henry Home (Lord Kames), and most importantly David Hume.....

Social norms – rules governing which behaviours are deemed appropriate or inappropriate within a given community – are typically taken to be uniquely human. Recently, this position has been challenged by a number of philosophers, cognitive scientists, and ethologists, who have suggested that social norms may also be found in certain non-human animal communities. Such claims have elicited considerable scepticism from norm cognition researchers, who doubt that any non-human animals possess the psychological capacities necessary for normative cognition. However, there is (...) little agreement among these researchers about what these psychological prerequisites are. This makes empirical study of animal social norms difficult, since it is not clear what we are looking for and thus what should count as behavioural evidence for the presence (or absence) of social norms in animals. To break this impasse, we offer an approach that moves beyond contested psychological criteria for social norms. This approach is inspired by the animal culture research program, which has made a similar shift away from heavily psychological definitions of ‘culture’ and to become organized around a cluster of more empirically tractable concepts of culture. Here, we propose an analogous set of constructs built around the core notion of a normative regularity, which we define as a socially maintained pattern of behavioural conformity within a community. We suggest methods for studying potential normative regularities in wild and captive primates. We also discuss the broader scientific and philosophical implications of this research program with respect to questions of human uniqueness, animal welfare and conservation. (shrink)

This paper is part of a project that is based on the notion of a dialectical system, introduced by Magari as a way of capturing trial and error mathematics. In Amidei et al. (2016, Rev. Symb. Logic, 9, 1–26) and Amidei et al. (2016, Rev. Symb. Logic, 9, 299–324), we investigated the expressive and computational power of dialectical systems, and we compared them to a new class of systems, that of quasi-dialectical systems, that enrich Magari’s systems with a natural mechanism (...) of revision. In the present paper we consider a third class of systems, that of p-dialectical systems, that naturally combine features coming from the two other cases. We prove several results about p-dialectical systems and the sets that they represent. Then we focus on the completions of first-order theories. In doing so, we consider systems with connectives, i.e. systems that encode the rules of classical logic. We show that any consistent system with connectives represents the completion of a given theory. We prove that dialectical and q-dialectical systems coincide with respect to the completions that they can represent. Yet, p-dialectical systems are more powerful; we exhibit a p-dialectical system representing a completion of Peano Arithmetic that is neither dialectical nor q-dialectical. (shrink)

Recently, Intelligent Tutoring Systems (ITS) got much attention from researchers even though ITS educational technology began in the late 1960s and ITS is just embryonic from laboratories into the field. In this paper we outline an intelligent tutoring system for teaching basics of the databases system called (MDB). The MDB was built as education system by using the authoring tool (ITSB). MDB contains learning materials as a group of lessons for beginner level which include relational database system and lessons in (...) the process to install and set up a database. MDB system has exams for each level of the Lessons. An evaluation was done to see the effectiveness the MDB among learners and instructors. The outcome of the evaluation was promising. (shrink)

The modal account of luck is the predominant account of luck in epistemology and ethics. In the first half of this paper, I discuss three possible interpretations of the modal account and raise objections to each. I then raise an objection to all plausible versions of the modal account, that is, that whether an event is lucky or the extent to which it is a matter of luck will depend on what initial conditions or features of the event one holds (...) constant across nearby possible worlds. However, there is often reasonable disagreement about what the relevant initial conditions of an event are, and the modal account of luck has no means of determining which description of the event is correct. As such, the modal account is subject to a kind of reference class problem, and the view cannot actually tell us the extent to which certain events are a matter of luck. (shrink)

This paper reviews the hole argument as an argument against spacetime substantivalism. After a careful presentation of the argument itself, I critically review possible responses.

I defend a new version of the non-identity theodicy. After presenting the theodicy, I reply to a series of objections. I then argue that my approach improves upon similar approaches in the literature.

Many philosophers, psychologists, and medical practitioners believe that killing is no worse than letting die on the basis of James Rachels's Bare-Difference Argument. I show that his argument is unsound. In particular, a premise of the argument is that his examples are as similar as is consistent with one being a case of killing and the other being a case of letting die. However, the subject who lets die has both the ability to kill and the ability to let die (...) while the subject who kills lacks the ability to let die. Modifying the latter example so that the killer has both abilities yields a pair of cases with morally different acts. The hypothesis that killing is worse than letting die is the best explanation of this difference. (shrink)

One might think that if the majority of virtue signallers judge that a proposition is true, then there is significant evidence for the truth of that proposition. Given the Condorcet Jury Theorem, individual virtue signallers need not be very reliable for the majority judgment to be very likely to be correct. Thus, even people who are skeptical of the judgments of individual virtue signallers should think that if a majority of them judge that a proposition is true, then that provides (...) significant evidence that the proposition is true. We argue that this is mistaken. Various empirical studies converge on the following point: humans are very conformist in the contexts in which virtue signalling occurs. And stereotypical virtue signallers are even more conformist in such contexts. So we should be skeptical of the claim that virtue signallers are sufficiently independent for the Condorcet Jury Theorem to apply. We do not seek to decisively rule out the relevant application of the Condorcet Jury Theorem. But we do show that careful consideration of the available evidence should make us very skeptical of that application. Consequently, a defense of virtue signalling would need to engage with these findings and show that despite our strong tendencies for conformism, our judgements are sufficiently independent for the Condorcet Jury Theorem to apply. This suggests new directions for the debate about the epistemology of virtue signalling. (shrink)

If moral properties lacked causal powers, would moral skepticism be true? I argue that it would. Along the way I respond to various arguments that it would not.

We address the ethics of scenarios in which one party entraps, intentionally tempts or intentionally tests the virtue of another. We classify, in a new manner, three distinct types of acts that are of concern, namely acts of entrapment, of intentional temptation and of virtue testing. Our classification is, for each kind of scenario, of itself neutral concerning the question whether the agent acts permissibly. We explain why acts of entrapment are more ethically objectionable than like acts of intentional temptation (...) and why these, in turn, are more ethically objectionable than like acts of virtue testing. Along the way, we scrutinize, and eventually reject, the view that acts of entrapment are ethically unacceptable because intentional temptation is involved in entrapment. (shrink)

In the first chapter of his Knowledge and Lotteries, John Hawthorne argues that thinkers do not ordinarily know lottery propositions. His arguments depend on claims about the intimate connections between knowledge and assertion, epistemic possibility, practical reasoning, and theoretical reasoning. In this paper, we cast doubt on the proposed connections. We also put forward an alternative picture of belief and reasoning. In particular, we argue that assertion is governed by a Gricean constraint that makes no reference to knowledge, and that (...) practical reasoning has more to do with rational degrees of belief than with states of knowledge. (shrink)

Our question is this: What makes an act one of entrapment? We make a standard distinction between legal entrapment, which is carried out by parties acting in their capacities as (or as deputies of) law- enforcement agents, and civil entrapment, which is not. We aim to provide a definition of entrapment that covers both and which, for reasons we explain, does not settle questions of permissibility and culpability. We explain, compare, and contrast two existing definitions of legal entrapment to commit (...) a crime that possess this neutrality. We point out some problems with the extensional correctness of these definitions and propose a new definition that resolves these problems. We then extend our definition to provide a more general definition of entrapment, encompassing both civil and legal cases. Our definition is, we believe, closer to being extensionally correct and will, we hope, provide a clearer basis for future discussions about the ethics of entrapment than do the definitions upon which it improves.

We make some remarks on the mathematics and metaphysics of the hole argument, in response to a recent article in this journal by Weatherall ([2018]). Broadly speaking, we defend the mainstream philosophical literature from the claim that correct usage of the mathematics of general relativity `blocks' the argument.

Empirical philosophers of science aim to base their philosophical theories on observations of scientific practice. But since there is far too much science to observe it all, how can we form and test hypotheses about science that are sufficiently rigorous and broad in scope, while avoiding the pitfalls of bias and subjectivity in our methods? Part of the answer, we claim, lies in the computational tools of the digital humanities, which allow us to analyze large volumes of scientific literature. Here (...) we advocate for the use of these methods by addressing a number of large-scale, justificatory concerns—specifically, about the epistemic value of journal articles as evidence for what happens elsewhere in science, and about the ability of DH tools to extract this evidence. Far from ignoring the gap between scientific literature and the rest of scientific practice, effective use of DH tools requires critical reflection about these relationships. (shrink)

People who report believing in God fear death. They also experience grief when someone they love dies. Philosophers and social scientists sometimes claim that this can only be plausibly explained by the hypothesis that people who claim to believe in God do not really believe in God. I show that this is mistaken. I identify three independently plausible explanations of why people who genuinely believe in God would have these behaviors and attitudes. First, there is an evolutionary explanation of why (...) the fear of death would be resilient even if one genuinely believes God has good things in store for us after death. Second, people often fear low probability outcomes. It may be that religious people are afraid of hell or the cessation of existence even if they judge those outcomes to have a low probability. Third, belief in God is typically combined with views according to which death is accompanied by the permanent loss and radical transformation of important relationships. (shrink)

Some legal theorists say that legal entrapment to commit a crime is incoherent. So far, there is no satisfactorily precise statement of this objection in the literature: it is obscure even as to the type of incoherence that is purportedly involved. (Perhaps consequently, substantial assessment of the objection is also absent.) We aim to provide a new statement of the objection that is more precise and more rigorous than its predecessors. We argue that the best form of the objection asserts (...) that, in attempting to entrap, law-enforcement agents lapse into a form of practical incoherence that involves the attempt simultaneously to pursue contrary ends. We then argue that the objection, in this form, encompasses all cases of legal entrapment only if it is supplemented by appeal to the premise that law-enforcement agents have an absolute duty never to create crimes.

Kopeikin (forthcoming a, forthcoming b) and Rachels’ (1975) bare-difference cases elicit the intuition that killing is no different than letting die. Hill’s (2018) bare-difference cases elicit the intuition that killing is worse than letting die. At least one of the intuitions must be mistaken. This calls for an error theory. Hill has an error theory for the intuition elicited by the Kopeikin/Rachels’ cases. Kopeikin and Rachels have an error theory for the intuition elicited by Hill’s cases. A (...) natural thought is that we are at an impasse. There is no plausible basis for preferring one error theory to the other. I argue that this natural thought is mistaken. Not all error theories are equal. Preliminary considerations favor Hill’s error theory and disfavor the Kopeikin/Rachels error theory. But preliminary considerations are not decisive. The way forward in the bare-difference debate is not to evaluate intuitions. The intuitions are in. What is left to do now is evaluate the comparative status of the Hill and the Kopeikin/Rachels error theories. (shrink)

In this paper I offer an argument against one important version of panentheism, that is, mereological panentheism. Although panentheism has proven difficult to define, I provide a working definition of the view, and proceed to argue that given this way of thinking about the doctrine, mereological accounts of panentheism have serious theological drawbacks. I then explore some of these theological drawbacks. In a concluding section I give some reasons for thinking that the classical theistic alternative to panentheism is preferable, all (...) things considered. (shrink)

It is often assumed that all lucky events are significant. The thought is that a chancy event such as winning the lottery is lucky for you in part because it affects your interests or well-being. But whether you win an Absurdist Raffle in which there are no prizes, is, intuitively, not a matter of luck. This is because this event—even if chancy—is not significant for any subject. However, a few philosophers have recently claimed not only that luck does not necessarily (...) involve a significance condition but that we should not view luck involving claims in terms of significance. After reviewing the literature on this topic, I argue that lucky events are significant. A significance condition is necessary to distinguish between different kinds of luck: practical, epistemic, and moral. All lucky events are significant and chancy, but they can be significant for subjects in different ways. For example, an event is epistemically lucky for you if it is epistemically significant and chancy, but such events need not affect your practical interests or moral standing. Furthermore, I argue that events that are chancy but not significant should be thought of in terms of chance and not luck. (shrink)

Many philosophers and members of the public think it is wrong to procreate. If one wants children, it is permissible to adopt. But procreation is allegedly impermissible because there is some respect in which adoption is better than procreation. I show that such objections are unsound.

Timothy Hsiao asks a good question: Why believe animals deserve moral consideration? His answer is that we should not. He considers various other answers and finds them wanting. In this paper I consider an answer Hsiao has not yet discussed: We should accept a conservative view about how to form beliefs. And such a view will instruct us to believe that animals deserve moral consideration. I think conservatives like Hsiao do best to answer his question in a way that upholds (...) the moral status of animals. Since my answer is one Hsiao has not yet addressed, it is compatible with the main points he makes against various other motivations in his many papers on this topic. So my paper should be understood as an invitation to Hsiao to consider another answer. (shrink)

I defend a solution to the puzzle of petitionary prayer based on some ideas of Aquinas, Gregory the Great, and contemporary desert theorists. I then address a series of objections. Along the way broader issues about the nature of desert, what is required for an action to have a point, and what is required for a puzzle to have a solution are discussed.

Why does God allow evil? One hypothesis is that God desires the existence and activity of free creatures but He was unable to create a world with such creatures and such activity without also allowing evil. If Molinism is true, what probability should be assigned to this hypothesis? Some philosophers claim that a low probability should be assigned because there are an infinite number of possible people and because we have no reason to suppose that such creatures will choose one (...) way rather than another. Arguments like this depend on the principle of indifference. But that principle is rejected by most philosophers of probability. Some philosophers claim that a low probability should be assigned because doing otherwise violates intuitions about freewill. But such arguments can be addressed through strategies commonly employed to defend theories with counterintuitive results across ethics and metaphysics. (shrink)

Some feminists hold that surrogacy contracts should be unenforceable or illegal because they contribute to and perpetuate unjust gender inequalities. I argue that in developed countries, surrogacy contracts either wouldn't have these negative effects or that these effects could be mitigated via regulation. Furthermore, the existence of a regulated surrogacy market is preferable on consequentialist grounds.

The view that folk psychology is primarily mindreading beliefs and desires has come under challenge in recent years. I have argued that we also understand others in terms of individual properties such as personality traits and generalizations from past behavior, and in terms of group properties such as stereotypes and social norms (Andrews 2012). Others have also argued that propositional attitude attribution isn’t necessary for predicting others’ behavior, because this can be done in terms of taking Dennett’s Intentional Stance (...) (Zawidzki 2013), appealing to social structures (Maibom 2007), shared norms (McGeer 2007) or via solution based heuristics for reaching equilibrium between social partners (Morton 2003). But it isn’t only prediction that can be done without thinking about what others think; we can explain and understand people in terms of their personality traits, habitual behaviors, and social practices as well. The decentering of propositional attitude attributions goes hand in hand with a move away from taking folk psychology to be primarily a predictive device. While experiments examining folk psychological abilities in children, infants, and other species still rest on asking subjects to predict behavior, theoretical investigations as to the evolutionary function of folk psychology have stressed the role of explanation (Andrews 2012) and regulative functions (McGeer 2007, Zawidzki 2013, Fenici 2011). In this paper I argue that an explanatory role for folk psychology is also a regulative role, and that language is not required for these regulative functions. I will start by drawing out the relationship between prediction, explanation, and regulation of behavior according to both mindreading approaches to folk psychology and the pluralistic account I defend. I will argue that social cognition does not take the form of causal reasoning so much as it does normative reasoning, and will introduce the folk psychological spiral. Then I will examine the cognitive resources necessary for participating in the folk psychological spiral, and I will argue that these cognitive resources can be had without language. There is preliminary evidence that some other species understand one another through a normative lens that, through looping effects, creates expectations that community members strive to live up to.

For any essential property God has, there is an ability He does not have. He is unable to bring about any state of affairs in which He does not have that property. Such inabilities seem to preclude omnipotence. After making trouble for the standard responses to this problem, I offer my own solution: God is not omnipotent. This may seem like a significant loss for the theist. But I show that it is not. The theist may abandon the doctrine that (...) God is omnipotent without scaling back the extent of His power and without denying that He has all perfections. (shrink)

This paper uses a schema for infinite regress arguments to provide a solution to the problem of the infinite regress of justification. The solution turns on the falsity of two claims: that a belief is justified only if some belief is a reason for it, and that the reason relation is transitive.

Lack of consent is valorized within popular culture to the point that sexual assault has become a spectator sport and creepshot entertainment on social media. Indeed, the valorization of nonconsensual sex has reached the extreme where sex with unconscious girls, especially accompanied by photographs as trophies, has become a goal of some boys and men.

In the following article I intend to examine the problem of the unity of the proposition in Russell, Frege, and Wittgenstein. My chief aim will be to draw attention to the distinction between Russell’s conception of propositional constituents, on the one hand, with Frege and Wittgenstein’s on the other. My focus will be on Russell’s view of terms as independent, propositions being built up out of these building blocks, compared with Frege and Wittgenstein’s ‘top down’ approach. Furthermore, I will argue (...) that, contra certain other commentators, Frege’s metaphor of saturation and unsaturation does not serve as a solution to the problem of unity, and that the extension of this metaphorical language to Wittgenstein is, therefore, inappropriate.

Immanuel Kant is known for his ideas about duty and morally worthy acts, but his conception of virtue is less familiar. Nevertheless Kant’s understanding of virtue is quite distinctive and has considerable merit compared to the most familiar conceptions. Kant also took moral education seriously, writing extensively on both the duty of adults to cultivate virtue and the empirical conditions to prepare children for this life-long responsibility. Our aim is, first, to explain Kant’s conception of virtue, second, to highlight some (...) distinctive and potentially appealing features of the Kantian account of virtue, third, to summarize and explain Kant’s prescriptions for educating young children and youth as well as the duty of moral self-improvement that he attributes to all adults, and, fourth, to respond to some common objections that we regard as misguided or insubstantial.

Ontologies, as the term is used in informatics, are structured vocabularies comprised of human- and computer-interpretable terms and relations that represent entities and relationships. Within informatics fields, ontologies play an important role in knowledge and data standardization, representation, integra- tion, sharing and analysis. They have also become a foundation of artificial intelligence (AI) research. In what follows, we outline the Coronavirus Infectious Disease Ontology (CIDO), which covers multiple areas in the domain of coronavirus diseases, including etiology, transmission, epidemiology, pathogenesis, diagnosis, (...) prevention, and treatment. We emphasize CIDO development relevant to COVID-19. (shrink)

In Algorithms & Autonomy, Rubel, Castro, and Pham (hereafter RCP), argue that the concept of autonomy is especially central to understanding important moral problems about algorithms. In particular, autonomy plays a role in analyzing the version of social contract theory that they endorse. I argue that although RCP are largely correct in their diagnosis of what is wrong with the algorithms they consider, those diagnoses can be appropriated by moral theories RCP see as in competition with their autonomy based theory. (...) Most notably, proponents of consequentialism and virtue ethics can appropriate RCPs insights. This is good news because RCP’s social contract theory is vulnerable to a well known class of counterexamples. The most significant contribution of RCP, if I am right, is in their identification, presentation, and evaluation of concrete cases involving algorithms and not in the more controversial claims about theoretical ethics that RCP themselves see as central to what they are doing.

This paper argues that underlying social biases are able to affect the processes underlying linguistic interpretation. The result is a series of harms systematically inflicted on marginalised speakers.

Epistemic accounts of luck define luck’s chanciness condition relative to a subject’s epistemic position. This could be put in terms of a subject’s evidence or knowledge about whether the event will occur. I argue that both versions of the epistemic account fail. In §2, I give two types of counterexamples to the evidence-based approach. In §3, I argue—contrary to the knowledge-based view—that an event can be a matter of good or bad luck for a subject even if she knows that (...) it will occur. In §4, I argue that epistemic accounts cannot explain some instances of constitutive luck. Because of these problems, luck’s chanciness condition cannot be adequately defined in epistemic terms.

I argue, through appeal to the distinction between analysis and decomposition described by Dummett, that Wittgenstein employs both of those notions in the Tractatus. I then bring this interpretation to bear upon the issue of propositional unity, where I formulate an objection to the views of both Leonard Linksy and José Zalabardo. I show that both Linsky and Zalabardo fail to acknowledge the distinction between analysis and decomposition present in the Tractatus, and that they consequently mischaracterise Wittgenstein’s position with respect (...) to propositional unity.

In this paper, I argue for a novel reading of Spinoza’s position in his exchangewith Boyle about Boyle’s experiment with nitre. Boyle claimed to have shownthrough experiments that nitre ceased to be nitre after heating. Spinozadisagreed and proposed the alternative hypothesis that nitre has changed itsstate and not its nature. Spinoza’s position was construed in the literature asrational scepticism denying that experiments can yield knowledge ofessences because all sensory experience is underdetermined and open tomultiple interpretations. I argue for an alternative (...) reading of Spinoza’sposition which focuses on Bacon’s notion of crucial instance. According tothis reading, Spinoza did not deny the possibility of knowing byexperimentation whether nitre has changed its nature, he asked for a crucialinstance, i.e. an experiment that would refute the hypothesis that nitre haschanged merely its state. Spinoza’s argumentative strategy shows that,contrary to the mainstream reading, the representational content of sensoryideas can be determined even if it does not represent the essence of theobject: we can know with absolute, rather than merely moral, certaintywhether nitre ceased to be nitre without knowing what nitre is.

This paper takes under consideration a piece by Roger Crisp in which he questions what the problem of moral luck can teach us about COVID-19 lockdown rule-breakers. Taking the position that although such rule-breakers might seem to be new examples of moral luck, Crisp ends up denying the existence of moral luck and argues that moral luck is an outdated notion in so far as it relies on other questionable aspects of morality, that is, retributivist punishment and blame. Although the (...) author agrees with Crisp that pandemic rule-breaker cases are putative examples of resultant moral luck, he proposes that Crisp has misconstrued what moral luck is and the paper examines in detail what he sees as the numerous problems with Crisp’s claims. The author concludes that Crisp’s analysis of pandemic rule-breaking does not shed any new light on the moral luck debate, and the difficult questions of luck, moral responsibility, and desert are not so easily resolved. -/- .

Strawsonian accounts of moral responsibility are widely associated with opposition to hard determinism. However, it is only an historical accident that these views are bundled together. I show that Strawson’s deepest commitments are perfectly consistent with, and even support, a new and improved form of hard determinism. The resulting view is not revisionist about our practices in the way that extant versions of hard determinism are. After setting out my view, I then turn to Latham and Tierney’s (2022) objection to (...) manipulation arguments. I make two points about their objection. First, while extant versions of hard determinism are vulnerable to Latham and Tierney’s objection, my version of hard determinism is not. Second, I argue that their objection raises important questions about what it is for two cases to be morally equivalent. I defend a principle about when cases are morally equivalent. My principle suggests a way to improve Latham and Tierny’s objection to manipulation arguments that are paired with extant variants of hard determinism. However, when paired with my version of hard determinism, manipulation arguments may accommodate Latham and Tierney’s objection. (shrink)

In the science of consciousness, it’s oftentimes assumed that some creatures (or mental states) are more conscious than others. But in recent years, a number of philosophers have argued that the notion of degrees of consciousness is conceptually confused. This paper (1) argues that the most prominent objections to degrees of consciousness are unsustainable, (2) examines the semantics of ‘more conscious than’ expressions, (3) develops an analysis of what it is for a degreed property to count as degrees of consciousness, (...) and (4) applies the analysis to various theories of consciousness. I argue that whether consciousness comes in degrees ultimately depends on which theory of consciousness turns out to be correct. But I also argue that most theories of consciousness entail that consciousness comes in degrees. (shrink)
