Evoke is a Python library for evolutionary simulations of signalling games. It offers a simple and intuitive API that can be used to analyze arbitrary game-theoretic models, and to easily reproduce and customize well-known results and figures from the literature.

Over the last fifteen years, an ambitious explanatory framework has been proposed to unify explanations across biology and cognitive science. Active inference, whose most famous tenet is the free energy principle, has inspired excitement and confusion in equal measure. Here, we lay the ground for proper critical analysis of active inference, in three ways. First, we give simplified versions of its core mathematical models. Second, we outline the historical development of active inference and its relationship to other theoretical approaches. Third, (...) we describe three different kinds of claim -- labelled mathematical, empirical and general -- routinely made by proponents of the framework, and suggest dialectical links between them. Overall, we aim to increase philosophical understanding of active inference so that it may be more readily evaluated. -/- This the final submitted version of the Introduction to the Topical Collection "The Free Energy Principle: From Biology to Cognition", forthcoming in Biology & Philosophy. (shrink)

The free energy principle is notoriously difficult to understand. In this paper, we relate the principle to a framework that philosophers of biology are familiar with: Ruth Millikan’s teleosemantics. We argue that: systems that minimise free energy are systems with a proper function; and Karl Friston’s notion of implicit modelling can be understood in terms of Millikan’s notion of mapping relations. Our analysis reveals some surprising formal similarities between the two frameworks, and suggests interesting lines of future research. We hope (...) this will aid further philosophical evaluation of the free energy principle. (shrink)

This paper aims to establish several interconnected points. First, a particular interpretation of the mathematical definition of information, known as the causal interpretation, is supported largely by misunderstandings of the engineering context from which it was taken. A better interpretation, which makes the definition and quantification of information relative to the function of its user, is outlined. The first half of the paper is given over to introducing communication theory and its competing interpretations. The second half explores three consequences of (...) the main thesis. First, a popular claim that the quantification of information in a signal is irrelevant for the meaning of that signal is exposed as fallacious. Second, a popular distinction between causal and semantic information is shown to be misleading, and I argue it should be replaced with a related distinction between natural and intentional signs. Finally, I argue that recent empirical work from microbiology and cognitive science drawing on resources of mathematical communication theory is best interpreted by the functional account. Overall, a functional approach is shown to be both theoretically and empirically well-supported. (shrink)

Hutto and Myin claim that teleosemantics cannot account for mental content. In their view, teleosemantics accounts for a poorer kind of relation between cognitive states and the world but lacks the theoretical tools to account for a richer kind. We show that their objection imposes two criteria on theories of content: a truth-evaluable criterion and an intensionality criterion. For the objection to go through, teleosemantics must be subject to both these criteria and must fail to satisfy them. We argue that (...) teleosemantics meets the truth-evaluable criterion and is not required to meet the intensionality criterion. We conclude that Hutto and Myin’s objection fails. (shrink)

The goal of this paper is to show that the information carried by a structural representation can be decomposed into the information carried by its component parts. In particular, the relations between the components of a structural representation carry quantifiable information about the relations between components of their signifieds. It follows that the information carried by cognitive structural representations, including cognitive maps, can in principle be quantified and decomposed. This is perhaps surprising given that the formal tools of communication theory (...) have typically only been applied to simpler representation-like states without significant structure, such as detectors or indicators. In the final section I consider using computational complexity theory to capture the processing advantages afforded by structural representation. (shrink)

This article establishes grounds on which attributions of information and encoding in animal signals are warranted. As common interest increases between evolutionary agents, the theoretical approach best suited to describing their interaction shifts from evolutionary game theory to communication theory, which warrants informational language. The take-home positive message is that in cooperative settings, signals can appropriately be described as transmitting encoded information, regardless of the cognitive powers of signalers. The canonical example is the honeybee waggle dance, which is discussed extensively (...) in the second and third sections. The take-home negative message is that signals are not always a consequence of coadaptation. The communication theory approach is just one end of a continuum explored more thoroughly by evolutionary game theory. The fourth and fifth sections explore this wider framework, as well as overturning some widely held misconceptions about information theory. (shrink)

Prominent views about representation share a premise: that mathematical communication theory is blind to representational content. Here I challenge that premise by rejecting two common misconceptions: that Claude Shannon said that the meanings of signals are irrelevant for communication theory (he didn't and they aren't), and that since correlational measures can't distinguish representations from natural signs, communication theory can't distinguish them either (the premise is true but the conclusion is false; no valid argument can link them).

In November 2022, OpenAI released ChatGPT, an incredibly sophisticated chatbot. Its capability is astonishing: as well as conversing with human interlocutors, it can answer questions about history, explain almost anything you might think to ask it, and write poetry. This level of achievement has provoked interest in questions about whether a chatbot might have something similar to human intelligence or even consciousness. Given that the function of a chatbot is to process linguistic input and produce linguistic output, we consider the (...) question whether a sophisticated chatbot might have inner speech. That is: Might it talk to itself, internally? We explored this via a conversation with ‘Playground’, a chatbot which is very similar to ChatGPT but more flexible in certain respects. We asked it questions which, plausibly, can only be answered if one first produces some inner speech. Here, we present our findings and discuss their philosophical significance. (shrink)

We propose a pluralist account of content for predictive processing systems. Our pluralism combines Millikan's teleosemantics with existing structural resemblance accounts. The paper has two goals. First, we outline how a teleosemantic treatment of signal passing in predictive processing systems would work, and how it integrates with structural resemblance accounts. We show that the core explanatory motivations and conceptual machinery of teleosemantics and predictive processing mesh together well. Second, we argue this pluralist approach expands the range of empirical cases to (...) which the predictive processing framework might be successfully applied. This is because our pluralism is practice-oriented. A range of different notions of content are used in the cognitive sciences to explain behaviour, and some of these cases look to employ teleosemantic notions. As a result, our pluralism gives predictive processing the scope to cover these cases. (shrink)

This study investigated how learner support services at the University of Calabar predict business education students' preparation for online learning. Two specific objectives were established, two research questions were posed, and two null hypotheses were developed and tested at a significant level of .05. Pertinent literature was reviewed. The population consisted of 147 University of Calabar 400-level business education students. This population also formed the sample using a census process. Data were gathered using a structured questionnaire with 40 items that (...) were validated by five specialists from the University of Calabar. Cronbach Alpha statistics were used to establish the questionnaire's reliability, yielding reliability coefficients of 0.88 and 0.85 for the independent sub-variables and dependent variable, respectively. Following the administration of the questionnaire, the data collected was analyzed using linear regression analysis to test the hypotheses. The results show that academic and technological support services strongly predict business education students' preparation for online instruction at the University of Calabar. Based on these findings, the study recommends that lecturers, counsellors, and academic technicians should encourage students to participate in digital education by offering intellectual, emotional, and other support services.

In this well-structured monograph, Stephen A. McKnight seeks to correct the view that Francis Bacon’s use of religious motifs and tropes is “manipulative,” “cynical,” and “disingenuous,” a view McKnight considers the “prevailing” one. To accomplish his goal, McKnight subjects several of Bacon’s works to a close reading. He concludes that the “pervasiveness of religious motifs, scriptural references, and biblical doctrines” in Bacon’s writings “establish the central role religion plays in Bacon’s thought”. McKnight holds that Bacon’s religiosity is not (...) disingenuous, but sincere. . . . . In documenting religious motifs in several of Bacon’s writings, this book is a valuable success. In characterizing Bacon’s religious beliefs and how they influenced the rest of his thought, it is much less convincing. (shrink)

McKnight’s The Religious Foundations of Francis Bacon’s Thought in arguing that Sir Francis Bacon was more deeply religious than he is conventionally thought to have been.

Those who know the corpus and secondary literature enough to read critically will find here provocative suggestions and intriguing leads.

The list also comments on Romanticism and the art of writing itself. The list on Hinduism is truly contrarian. One hopes that this list survives when GoodReads and other Listopias are no longer. -/- Today's academia is obsessed about writing and speaking gobbledygook. At least most of the time.

According to Partial Aggregation, a serious harm can be outweighed by a large number of somewhat less serious harms, but can outweigh any number of trivial harms. In this paper, I address the question of how we should extend Partial Aggregation to cases of risk, and especially to cases involving small risks of serious harms. I argue that, contrary to the most popular versions of the ex ante and ex post views, we should sometimes prevent a small risk that a (...) large number of people will suffer serious harms rather than prevent a small number of people from certainly suffering the same harms. Along the way, I object to the ex ante view on the grounds that it gives an implausible degree of priority to preventing identified over statistical harms, and to the ex post view on the grounds that it fails to respect the separateness of persons. An insight about the nature of claims emerges from these arguments: there are three conceptually distinct senses in which a person’s claim can be said to have a certain degree of strength. I make use of the distinction between these three senses in which a claim can be said to have strength in order to set out a new, more plausible, view about the aggregation of people’s claims under risk.

There is conflicting experimental evidence about whether the “stakes” or importance of being wrong affect judgments about whether a subject knows a proposition. To date, judgments about stakes effects on knowledge have been investigated using binary paradigms: responses to “low” stakes cases are compared with responses to “high stakes” cases. However, stakes or importance are not binary properties—they are scalar: whether a situation is “high” or “low” stakes is a matter of degree. So far, no experimental work has investigated the (...) scalar nature of stakes effects on knowledge: do stakes effects increase as the stakes get higher? Do stakes effects only appear once a certain threshold of stakes has been crossed? Does the effect plateau at a certain point? To address these questions, we conducted experiments that probe for the scalarity of stakes effects using several experimental approaches. We found evidence of scalar stakes effects using an “evidence seeking” experimental design, but no evidence of scalar effects using a traditional “evidence-fixed” experimental design. In addition, using the evidence-seeking design, we uncovered a large, but previously unnoticed framing effect on whether participants are skeptical about whether someone can know something, no matter how much evidence they have. The rate of skeptical responses and the rate at which participants were willing to attribute “lazy knowledge”—that someone can know something without having to check—were themselves subject to a stakes effect: participants were more skeptical when the stakes were higher, and more prone to attribute lazy knowledge when the stakes were lower. We argue that the novel skeptical stakes effect provides resources to respond to criticisms of the evidence-seeking approach that argue that it does not target knowledge. (shrink)

This paper champions the view (REG) that the concept of a normative reason for an agent S to perform an action A is that of an explanation why it would be good (in some way, to some degree) for S to do A. REG has numerous virtues, but faces some significant challenges which prompt many philosophers to be skeptical that it can correctly account for all our reasons. I demonstrate how five different puzzles about normative reasons can be solved by (...) attention to the concept of goodness, and in particular observing the ways in which it—and consequently, talk about reasons—is sensitive to context (ends and information). Rather than asking simply whether or not certain facts are reasons for S to do A, we need to explore the contexts in which it is and is not correct to describe a certain fact as “a reason” for S to do A. These five puzzles concern: (1) reasons for attitudes of the “right kind”, (2) evidence as reasons, (3) normative facts as reasons, (4) subjective reasons, and (5) attitudes as reasons. (shrink)

An overview of the ancient philosophers and their philosophical system (divided into the fields of logic, physics, and ethics) comprising the living, organic, enduring, and evolving body of interrelated ideas identifiable as the Stoic perspective.

This article is a rebuttal to Robert G. Cavin and Carlos A. Colombetti’s article, “Assessing the Resurrection Hypothesis: Problems with Craig’s Inference to the Best Explanation,” which argues that the Standard Model of current particle physics entails that non-physical things (like a supernatural God or a supernaturally resurrected body) can have no causal contact with the physical universe. As such, they argue that William Lane Craig’s resurrection hypothesis is not only incompatible with the notion of Jesus physically appearing to the (...) disciples, but the resurrection hypothesis is significantly limited in both its explanatory scope and explanatory power. This article seeks to demonstrate why their use of the Standard Model does not logically entail a rejection of the physical resurrection of Jesus when considering the scope and limitations of science itself.

This paper investigates the strange case of an argument that was directed against a positivist verification principle. We find an early occurrence of the argument in a talk by the phenomenologist Roman Ingarden at the 1934 International Congress of Philosophy in Prague, where Carnap and Neurath were present and contributed short rejoinders. We discuss the underlying presuppositons of the argument, and we evaluate whether the attempts by Carnap (especially) actually succeed in answering this argument. We think they don’t, and offer (...) instead a few sociological thoughts about why the argument seems to have disappeared from the profession’s evaluaton of the positivist criterion of verifiability.

Sufferers of eating disorders often hold false beliefs about their own body size. Such beliefs appear to violate norms of rationality, being neither grounded by nor responsive to appropriate forms of evidence. I defend the rationality of these beliefs.

This argument has far‐reaching implications for the explanation and treatment of eating disorders, as well as debates over the relationship between rationality and human (...) psychology. (shrink)

The purpose of this essay is to offer support for the substance view of persons, the philosophical anthropology defended by Patrick Lee in his essay.

Despite being a common phenomenon with significant consequences on our everyday life, strikes (and direct actions in general) are still relatively undertheorized in the philosophical literature. Our paper has a specific focus that is best encapsulated in a question: What is the relationship between liberalism and the right to strike? Liberalism’s cornerstone is the idea that rights and liberties of individuals are of supreme political importance. Rights and liberties, however, are not created equal. The basic liberties are those that are (...) so politically important that legal restrictions upon them are unjustified unless to protect other basic liberties within an overall scheme of liberties, such as under a bill of rights. So, our question becomes: Is the right to strike a basic liberty? Two ongoing disputes are relevant here. The ‘older’ debate concerns the status of economic liberties and their relation to the right to strike. We will focus on a ‘newer’ discussion because it poses a challenge to liberalism itself. Namely, some ‘radical’ critics of liberalism (Gourevitch, Raekstad and Rossi) have argued that there are rights that involve coercing others, exercised during strikes or engagement in other direct action, that do not qualify as liberal basic liberties and that can sometimes take normative precedence over the liberal basic liberties. This criticism, if correct, defeats liberalism. Notice, though: since the weighing of different particular basic liberties against each other in an overall scheme of liberty is integral to high liberalism, the genuine threat that the radical critique poses stems not from the second conjunct (which its proponents have defended) but from its first (which they have merely assumed). For, if (contrary to what the radical work assumes) the right to engage in coercive strike action is a liberal basic liberty then it can, at least in principle, win out over other basic liberties, within an overall scheme of liberties, in situations of prima facie moral conflict. Raekstad and Rossi extend the radical critique, beyond the case of coercive strikes, to other forms of direct action (outside of industrial disputes) that have avowedly moral or political goals. These could include workplace occupations, street blockades, hacktivism, counter-economics, tax resistance and more. In the paper we argue that the ‘radicals’ are not entitled to the assumption that the right to strike is not a liberal basic liberty. Moreover, we suggest, high liberalism has the resources to accommodate not only a general right to engage in non-coercive strike action, but also the right to engage in some forms of coercive direct action, whether as part of an industrial dispute or not. More precisely, we show that liberalism has the resources to accommodate not only (i) a general right to engage in non-coercive strike action, but also (ii) the right to engage in some forms of coercive direct action, whether (iii) as part of an industrial dispute or (iv) not.

The ancient Stoics believed that virtue is the only true good and as such both necessary and sufficient for happiness. Accordingly, they classified food as among the things that are neither good nor bad but "indifferent." These "indifferents" included health, illness, wealth, poverty, good and bad reputation, life, death, pleasure, and pain. How one deals with having or lacking these things reflects one’s virtue or vice and thus determines one’s happiness or misery. So, while the Stoics held that food in (...) itself contributes nothing to a person’s happiness, how one obtains, prepares, and serves it, and both what and how one eats, all reveal a person’s character as good or bad. Thus, understanding the purpose of food, the necessity of frugality, and the virtue of temperance are all important in Stoicism. This paper traces the ethical views on food from Zeno of Citium and Chrysippus to Seneca, Musonius Rufus, Epictetus, and Marcus Aurelius. They agree that the wise and temperate know that simple, inexpensive foods in moderate amounts produced locally are easy to get and prepare, healthy for the body, and good for the mind. Thus, Stoicism dictates frugality of diet and the rejection of ambitious eating, gluttony, luxuries, delicacies, and gustatory extravagance. Some Stoics favor vegetarianism. All Stoics think it wise to limit eating and drinking to strict bodily need and to eradicate all food anxieties. (shrink)

Models are the coin of the realm in current philosophy of science, as they are in science itself, having replaced laws and theories as the primary strategy. Logical Positivism tried to erase the older neo-Kantian distinction between ideal constructions and reality. It returns in the case of models. Nowak’s concept of idealization pro- vided an alternative account of this issue. It construed model application as concretizations of hypotheses which improve by accounting for exceptions. This appears to account for physical law. (...) But it raises the problem of uniqueness: is the result unique, as physical law should be? Neo-Kantianism failed this test. Its solutions were circular justifications for claims of uniqueness. Nowak inherited the problem without resolving it. (shrink)

Levy (2021 Levy, N. (2021). Bad beliefs: Why they happen to good people. Oxford University Press.[Crossref], [Google Scholar]) argues that bad beliefs predominately stem from automatic (albeit rational) updating in response to testimonial evidence. To counteract such beliefs, then, we should focus on ridding our epistemic environments of misleading testimony. This paper responds as follows. First, I argue that the suite of automatic processes related to bad beliefs extends well beyond the deference-based processes that Levy identifies. Second, I push back (...) against Levy’s claim that bad beliefs stem from wholly rational processes, suggesting that, in many cases, such processes are better characterized as arational. Finally, I note that Levy is too quick to dismiss the role that individuals can play in cleaning up their own epistemic environments, and I suggest one route through which this is possible. (shrink)

Tracing the leading role of emotions in the evolution of the mind, a philosopher and a psychologist pair up to reveal how thought and culture owe less to our faculty for reason than to our capacity to feel. Many accounts of the human mind concentrate on the brain’s computational power. Yet, in evolutionary terms, rational cognition emerged only the day before yesterday. For nearly 200 million years before humans developed a capacity to reason, the emotional centers of the brain were (...) hard at work. If we want to properly understand the evolution of the mind, we must explore this more primal capability that we share with other animals: the power to feel. Emotions saturate every thought and perception with the weight of feelings. The Emotional Mind reveals that many of the distinctive behaviors and social structures of our species are best discerned through the lens of emotions. Even the roots of so much that makes us uniquely human—art, mythology, religion—can be traced to feelings of caring, longing, fear, loneliness, awe, rage, lust, playfulness, and more. From prehistoric cave art to the songs of Hank Williams, Stephen T. Asma and Rami Gabriel explore how the evolution of the emotional mind stimulated our species’ cultural expression in all its rich variety. Bringing together insights and data from philosophy, biology, anthropology, neuroscience, and psychology, The Emotional Mind offers a new paradigm for understanding what it is that makes us so unique.

This paper focuses on the fact that AI is predominantly portrayed as white—in colour, ethnicity, or both. We first illustrate the prevalent Whiteness of real and imagined intelligent machines in four categories: humanoid robots, chatbots and virtual assistants, stock images of AI, and portrayals of AI in film and television. We then offer three interpretations of the Whiteness of AI, drawing on critical race theory, particularly the idea of the White racial frame. First, we examine the extent to which this (...) Whiteness might simply reflect the predominantly White milieus from which these artefacts arise. Second, we argue that to imagine machines that are intelligent, professional, or powerful is to imagine White machines because the White racial frame ascribes these attributes predominantly to White people. Third, we argue that AI racialised as White allows for a full erasure of people of colour from the White utopian imaginary. Finally, we examine potential consequences of the racialisation of AI, arguing it could exacerbate bias and misdirect concern. (shrink)

This paper investigates whether different philosophers’ claims about “normativity” are about the same subject or (as recently argued by Derek Parfit) theorists who appear to disagree are really using the term with different meanings, in order to cast disambiguating light on the debates over at least the nature, existence, extension, and analyzability of normativity. While I suggest the term may be multiply ambiguous, I also find reasons for optimism about a common subject-matter for metanormative theory. This is supported partly by (...) sketching a special kind of hybrid view of normative judgment, perspectivism, that occupies a position between cognitivism and noncognitivism, naturalism and nonnaturalism, objectivism and subjectivism, making it more plausible that radically different metanormative theories could be about the same thing. I explore three main fissures: between (i) the “normativity” of language/thought versus that of facts and properties, (ii) abstract versus substantive senses, and (iii) formal versus robust senses.

[Stephen Yablo] The usual charge against Carnap's internal/external distinction is one of 'guilt by association with analytic/synthetic'. But it can be freed of this association, to become the distinction between statements made within make-believe games and those made outside them-or, rather, a special case of it with some claim to be called the metaphorical/literal distinction. Not even Quine considers figurative speech committal, so this turns the tables somewhat. To determine our ontological commitments, we have to ferret out all traces (...) of nonliterality in our assertions; if there is no sensible project of doing that, there is no sensible project of Quinean ontology. /// [Andre Gallois] I discuss Steve Yablo's defence of Carnap's distinction between internal and external questions.

In the third section I say why Carnap's application of the distinction between internal and external questions runs into trouble. In the fourth section I spell out what I take to be Yablo's version of Carnap. In the last I say why that version is especially vulnerable to the objection raised in the second. (shrink)

It has long been known that in the context of axiomatic second-order logic (SOL), Hume's Principle (HP) is mutually interpretable with "the universe is Dedekind infinite" (DI). I offer a more fine-grained analysis of the logical strength of HP, measured by deductive implications rather than interpretability. The main result is that HP is not deductively conservative over SOL + DI. That is, SOL + HP proves additional theorems in the language of pure second-order logic that are not provable from SOL (...) + DI alone. Arguably, then, HP is not just a pure axiom of infinity, but rather it carries additional logical content. On the other hand, I show that HP is $\Pi^1_1$ conservative over SOL + DI, and that HP is conservative over SOL + DI + "the universe is well ordered" (WO). Next, I show that SOL + HP does not prove any of the simplest and most natural versions of the axiom of choice, including WO and weaker principles. Lastly, I discuss other axioms of infinity. I show that HP does not prove the Splitting or Pairing principles (axioms of infinity stronger than DI). (shrink)

Intuitions play an important role in contemporary epistemology. Over the last decade, however, experimental philosophers have published a number of studies suggesting that epistemic intuitions may vary in ways that challenge the widespread reliance on intuitions in epistemology. In a recent paper, Jennifer Nagel offers a pair of arguments aimed at showing that epistemic intuitions do not, in fact, vary in problematic ways. One of these arguments relies on a number of claims defended by appeal to the psychological literature on (...) intuitive judgment and on mental state attribution (also known as “theory of mind”, “mindreading” and “folk psychology”). I call this the "theoretical argument". The other argument relies on recent experimental work carried out by Nagel and her collaborators. It is my contention that in setting out her theoretical argument, Nagel offers an account of the relevant scientific literature that is, in crucial respects, flawed and misleading. My main goal in this paper is to rectify these errors and to make it clear that, once this is done, Nagel’s theoretical argument collapses. Since Nagel’s experimental work has not yet been published, and available details are very sketchy, I do not discuss this work in detail. However, in the final section of the paper I offer some critical observations about Nagel’s strategy for dealing with empirical data that does not support her view – both other people’s and her own.

Stephen Palmquist is Professor of Religion and Philosophy at Hong Kong Baptist University. We invited him to answer the question "What norms or values define excellent philosophy of religion? as part of our "Philosophers of Religion on Philosophy of Religion" series. If we regard this as a philosophical (not a scientific) question, then the first step to answering it is to determine what norms or values define excellent philosophy, in general. Once that is established, we can inquire whether the (...) nature of religion brings with it any special features that make the task of doing excellent philosophy of religion unique. Unlike scientific explanations, excellent philosophical explanations must be multi-perspectival. A question that has only one right answer is not philosophical; instead, it is likely to be about facts. While we philosophers should care (deeply!) about any facts relevant to our inquiries, our peculiar way of interpreting facts means that answering a philosophical question cannot be done in one absolutely "right" way. This does not mean there are no right answers to philosophical questions; rather, there are many. But this does not make any answer equally good; for there would then be no such thing as excellent philosophy. The essentially perspectival nature of all genuinely philosophical questions means that the correctness of each purportedly "right" answer must be assessed in terms of its aptness for the perspective the questioner adopts when posing the question. A single question, such as "Does God exist?" can have many good answers, depending on whether the questioner assumes science, morality, aesthetics, or something else as the context. Each different type of inquiry has different boundary-conditions, so a good answer within each context is bound to differ from those in other contexts. Bad philosophy typically lacks depth: like a cyclops, its approach to answering questions is mono-perspectival. But if good philosophy acknowledges perspectives, what makes philosophy excellent? Good philosophy achieves excellence when it approaches a completeness whereby we begin to understand the range of relevant perspectives from which a given question can be asked, and the distinct boundary-conditions for answering it properly from each relevant perspective. Before applying this definition of excellent philosophy to the specific case at hand, we must pause to consider whether anything distinctive characterizes the range of philosophical topics and questions that typically come under the umbrella of philosophy of religion. In particular, does religion have features that make it especially difficult (or for that matter, easy) to think about philosophically, compared to other philosophical topics? Yes and no. (shrink)

….it [is] wholly irrational to regard as doubtful matters that are perceived clearly and distinctly by the understanding in its purity, on account of mere prejudices of the senses and hypotheses in which there is an element of the unknown.Descartes, Geometrical Exposition of the MeditationsSubstance dualism, once a main preoccupation of Western metaphysics, has fallen strangely out of view; today’s mental/physical dualisms are dualisms of fact, property, or event. So if someone claims to find a difference between minds and bodies (...) per se, it is not initially clear what he is maintaining. Maybe this is because one no longer recognizes ‘minds’ as entities in their own right, or ‘substances.’ However, selves - the things we refer to by use of ‘I’ - are surely substances, and it does little violence to the intention behind mind/body dualism to interpret it as a dualism of bodies and selves. If the substance dualist’s meaning remains obscure, that is because it can mean several different things to say that selves are not bodies. (shrink)

Many intelligent, capable, and successful individuals believe that their success is due to luck and fear that they will someday be exposed as imposters. A puzzling feature of this phenomenon, commonly referred to as imposter syndrome, is that these same individuals treat evidence in ways that maintain their false beliefs and debilitating fears: they ignore and misattribute evidence of their own abilities, while readily accepting evidence in favour of their inadequacy. I propose a novel account of imposter syndrome as an (...) instance of self-deception, whereby biased evidence treatment is driven by the motivational benefit of negative self-appraisal. This account illuminates a number of interconnected philosophical and scientific puzzles related to the explanation, definition, and value of imposter syndrome. (shrink)

Some philosophers object to moral error theory by arguing that there a parity between moral and epistemic normativity. They maintain that moral and epistemic error theory stand or fall together, that epistemic error theory falls, and that moral error theory thus falls too. This paper offers a response to this objection on behalf of moral error theorists. I defend the view that moral and epistemic error theory do not stand or fall together by arguing that moral error theory can be (...) sustained alongside epistemic expressivism. This unusual combination of theories can be underpinned by differences in the foundational norms that guide moral and epistemic inquiry. I conclude that the problem of epistemic normativity fails to show that it is compulsory for us to reject moral error theory. (shrink)

This paper proposes an abstract mathematical frame for describing some features of biological time. The key point is that usual physical (linear) representation of time is insufficient, in our view, for the understanding key phenomena of life, such as rhythms, both physical (circadian, seasonal …) and properly biological (heart beating, respiration, metabolic …). In particular, the role of biological rhythms do not seem to have any counterpart in mathematical formalization of physical clocks, which are based on frequencies along the usual (...) (possibly thermodynamical, thus oriented) time. We then suggest a functional representation of biological time by a 2-dimensional manifold as a mathematical frame for accommodating autonomous biological rhythms. The “visual” representation of rhythms so obtained, in particular heart beatings, will provide, by a few examples, hints towards possible applications of our approach to the understanding of interspecific differences or intraspecific pathologies. The 3- dimensional embedding space, needed for purely mathematical reasons, allows to introduce a suitable extra-dimension for “representation time”, with a cognitive significance. (shrink)

After reviewing Kant’s well-known criticisms of the traditional proofs of God’s existence and his preferred moral argument, this paper presents a detailedanalysis of a densely-packed theistic argument in Religion within the Bounds of Bare Reason. Humanity’s ultimate moral destiny can be fulfilled only through organized religion, for only by participating in a religious community (or “church”) can we overcome the evil in human nature. Yet we cannot conceive how such a community can even be founded without presupposing God’s existence. Viewing (...) God as the internal moral lawgiver, empowering a community of believers, is Kant’s ultimate rationale for theistic belief. (shrink)

Autonomous systems are machines that can alter their behavior without direct human oversight or control. How ought we to program them to behave? A plausible starting point is given by the Reduction to Acts Thesis, according to which we ought to program autonomous systems to do whatever a human agent ought to do in the same circumstances. Although the Reduction to Acts Thesis is initially appealing, we argue that it is false: it is sometimes permissible to program a machine to (...) do something that it would be wrong for a human to do. We advance two main arguments for this claim. First, the way an autonomous system will behave can be known in advance. This knowledge can indirectly affect the behavior of other agents, while the same may not be true at the time the system actually executes its programming. Second, a lack of knowledge of the identities of the victims and beneficiaries can provide a justification during the programming phase that would be unavailable to an agent at the time the autonomous system executes its programming.

Korean translation of "Kant's Critical Hermeneutic of Prayer".

I argue that Schopenhauer’s ascription of (moral) rights to animals flows naturally from his distinctive analysis of the concept of a right. In contrast to those who regard rights as fundamental and then cast wrongdoing as a matter of violating rights, he takes wrong (Unrecht) to be the more fundamental notion and defines the concept of a right (Recht) in its terms. He then offers an account of wrongdoing which makes it plausible to suppose that at least many animals can (...) be wronged and thus, by extension, have rights. The result, I argue, is a perspective on the nature of moral rights in general, and the idea of animal rights in particular, that constitutes an important and plausible alternative to the more familiar views advanced by philosophers in recent decades.

The Roman imperial Stoics were familiar with exile. This paper argues that the Stoics’ view of being a refugee differed sharply from their view of what is owed to refugees. A Stoic adopts the perspective of a cosmopolitēs, a “citizen of the world,” a rational being everywhere at home in the universe. Virtue can be cultivated and practiced in any locale, so being a refugee is an “indifferent” that poses no obstacle to happiness. Other people are our fellow cosmic citizens, (...) however, regardless of their language, race, ethnicity, customs, or country of origin. Our natural affinity and shared sociability with all people require us to help refugees and embrace them as welcome neighbors. Failure to do so violates our common reason, justice, and the gods’ cosmic law. (shrink)
