In statistics, there are two main paradigms: classical and Bayesian statistics. The purpose of this article is to investigate the extent to which classicists and Bayesians can agree. My conclusion is that, in certain situations, they cannot. The upshot is that, if we assume that the classicist is not allowed to have a higher degree of belief in a null hypothesis after he has rejected it than before, then he has to either have trivial or incoherent credences to begin with (...) or fail to update his credences by conditionalization.

How do you know what you want? Philosophers have lately developed sophisticated accounts of the practical and doxastic knowledge that are rooted in the point of view of the subject. Our ability to just say what we are doing or what we believe—that is, to say so authoritatively, but not on the basis of observation or evidence—is an aspect of our ability to reason about the good and the true. However, no analogous route to orectic self-knowledge is feasible. Knowledge of (...) desire is distinctive in being a matter of our affective response to imagined prospects. An examination of this idea yields the following thesis: I know what I want just in case the object pursued in anticipation of a certain pleasure actually yields the anticipated pleasure. (shrink)

For a period of several years the philosopher of science Hasok Chang has promoted various inter-related views including pluralism, pragmatism, and an associated view of natural kinds. He has also argued for what he calls the persistence of everyday terms in the scientific view. Chang claims that terms like phlogiston were never truly abandoned but became transformed into different concepts that remain useful. On the other hand, Chang argues that some scientific terms such as acidity have suffered a form of (...) “rupture”, especially in the case of the modern Lewis definition of acids. Chang also complains that the degree of acidity of a Lewis acid cannot be measured using a pH meter and seems to regard this as a serious problem. The present paper examines some of these views, especially what Chang claims to be a rupture in the definition of acidity. It is suggested that there has been no such rupture but a genuine generalization, on moving from the Brønsted-Lowry theory to the Lewis theory of acidity. It will be shown how the quantification and measurement of Lewis acidity can easily be realized through the use of equilibrium theory and the use of stability constants. (shrink)

In reasoning, we draw conclusions from multiple premises. But thinkers can be fragmented. And if there is no single fragment of the agent that thinks all of the premises, then the agent cannot draw any conclusions from them. It follows that reasoning from multiple premises depends on their being thought together. But what is it to think premises together? What is the condition that contrasts with fragmentation? This paper provides an answer to this question that is simple but compelling: to (...) think premises together is to attribute those very thoughts to one and the same self. The ability to reason depends on the ability to attribute the thoughts from which one reasons to oneself. Reasoning—at least the sort of reasoning that we do—requires de se thought. (shrink)

The notion of domain specificity plays a central role in some of the most important debates in cognitive science. Yet, despite the widespread reliance on domain specificity in recent theorizing in cognitive science, this notion remains elusive. Critics have claimed that the notion of domain specificity can't bear the theoretical weight that has been put on it and that it should be abandoned. Even its most steadfast proponents have highlighted puzzles and tensions that arise once one tries to go beyond (...) an initial intuitive sketch of what domain specificity involves. In this paper, we address these concerns head on by developing an account of what it means for a cognitive mechanism to be domain specific that overcomes the obstacles that have made domain specificity seem so problematic. We then apply this understanding of domain specificity to one of the key debates that it has figured prominently in—the rationalism-empiricism debate concerning the origins of cognitive traits—and introduce several related theoretical notions that work alongside domain specificity in helping to clarify what makes a view more (or less) rationalist. This example illustrates how the notion of domain specificity can, and should, continue to play a central role in ongoing debates in cognitive science. (shrink)

I argue that central to Aristotle’s account of vice is a distinction between two varieties of vicious person: those for whom character change is possible (the curable), and those for whom it is not (the incurable). Recognizing this distinction and drawing out the ideas which ground it shows why Aristotle’s discussions of vice in EN vii and ix 4 are not inconsistent.

I argue that Smith proposed a new kind of imperialism, which we would describe as a species of ‘federalism,’ and that his plan influenced Bentham and Kant in their federal projects, although they seem to have been unaware of each other’s proposals. In what follows, I outline Smith’s position. I then describe Kant’s and Bentham’s debts to Smith in turn. This will also allow for greater clarity about the nature of early liberalism.

Our interest in understanding belief stems partly from our being creatures who think. However, the term ‘belief’ is used to refer to many states: from the fully conscious rational state that partly constitutes knowledge to the fanciful states of alarm clocks. Which of the many ‘belief’ states must a theory of belief be answerable to? This is the scope question. I begin my answer with a reply to a recent argument that belief is invariably weak, i.e., that the evidential standards (...) that are required for belief are low. Although one state we refer to using the term ‘belief’ fits this profile, other ‘belief’ states do not. Crucially, when ‘belief’ is heard in a weak sense, it attributes a state that only a rational creature can be in. I will use this observation as a starting point for an argument that the study of (our) belief should not be constrained by the requirement that the illuminated state be held in common with any non-rational being. This lends support to the Transformative Theory of Rationality, according to which rationality does not merely add powers or complexity to the animal mind, but transforms it into a different kind of mind altogether.

In this paper, we argue that promoting patient values is a legitimate goal of medicine. Our view offers a justification for certain current practices, including birth control and living organ donation, that are widely accepted but do not fit neatly within the most common extant accounts of the goals of medicine. Moreover, we argue that recognising value promotion as a goal of medicine will expand the scope of medical practice by including some procedures that are sometimes rejected as being outside (...) the scope of acceptable medical practice, such as certain forms of physician-assisted death. We then rebut some common and possible objections to this view. Our aim is not to argue that other accounts are mistaken—except when they argue for a single goal that does not include patient values—but rather to show that value promotion should play a more central role in discussions about the goals of medicine.

The advanced division of cognitive labor generates a set of challenges and opportunities for professional philosophers. In this paper, I re-characterize the nature of synthetic philosophy in light of these challenges and opportunities. In part 1, I’ll remind you of the centrality of the division of labor to Plato’s Republic, and why this is especially salient in his banishment of the poets from his Kallipolis. I’ll then focus on the significance of an easily overlooked albeit rather significant character, Damon, mentioned (...) in that dialogue. I’ll argue that if we take the relationship between Socrates and Damon seriously, we’ll notice that in modeling imperfect polities, Plato inscribes Socrates within the advanced division of cognitive labor who defers to Damon as an expert on a key feature of the art of government. In fact, I’ll argue that in Republic, Plato offers us at least two ways to conceptualize philosophy’s relationship to the sciences, and that he alerts us to the social significance of this. In part 2, I’ll re-introduce my conceptualization of synthetic philosophy and restate it. Back in 2019 I published a short paper on it that went viral and was immediately used by others. Reflection on their use instructed me about an ambiguity in my position. Building on the material in parts 1-2, in part 3, I’ll contrast my account with a number of ways that Philip Kitcher has conceptualized synthetic philosophy in order to make more precise the version promoted here.

Here I consider the two most venerated arguments about the existence of God: the Ontological Argument and the Argument from Evil. The Ontological Argument purports to show that God’s nature guarantees that God exists. The Argument from Evil purports to show that God’s nature, combined with some plausible facts about the way the world is, guarantees (or is very compelling grounds for thinking) that God does not exist. Obviously, both arguments cannot be sound. But I argue here that they are (...) both unsound for the very same reason. (shrink)

According to the analysis of concessive conditionals suggested by Crupi and Iacona, a concessive conditional $$p{{\,\mathrm{\hookrightarrow }\,}}q$$ p ↪ q is adequately formalized as a conjunction of conditionals. This paper presents a sound and complete axiomatic system for concessive conditionals so understood. The soundness and completeness proofs that will be provided rely on a method that has been employed by Raidl, Iacona, and Crupi to prove the soundness and completeness of an analogous system for evidential conditionals.

Although advance directives are widely believed to be a key way to safeguard the autonomy of incompetent medical patients, significant questions exist about their moral authority. The main philosophical concern involves cases in which an incompetent patient no longer possesses the desires on which her advance directive was based. The question is, does that entail that prior expressions of medical choices are no longer morally binding? I believe that the answer is “yes.” I argue that a patient’s autonomy is not (...) respected by honoring the desires she used to have but no longer does. I also consider and reject the view that honoring an advance directive that reflects the patient’s previous values must be in that patient’s best interests. If that is correct, then advance directives in the kind of case at issue are not morally binding. (shrink)

Legal theorists seek to persuade other jurists of certain theories: Textualism or purposivism; formalism or realism; natural law theory or positivism; prison reform or abolition; universal or particular human rights? Despite voluminous literature about these debates, tremendous uncertainty remains about which views experts endorse. This Article presents the first-ever empirical study of American law professors about legal theory questions. A novel dataset of over six hundred law professors reveals expert consensus and dissensus about dozens of longstanding legal theory debates. -/- (...) Law professors also debate questions about the nature of the legal academy. Descriptively, which subjects (e.g. constitutional law) and methods (e.g. law & economics) are most central within the legal academy today? And prescriptively, should today’s legal academy prioritize additional areas (e.g. legislation) or methods (e.g. critical race theory)? There is great interest in these questions but no empirical dataset of experts’ views; this results in uncertainty about which views experts endorse. This Article’s empirical study also clarifies these questions, documenting law professors’ evaluation of over one-hundred areas of law. -/- The legal theory and legal academy findings support implications for legal scholarship, education, and practice. Clearly, debates about law and the legal academy’s evolution should not be settled by a survey. Nevertheless, insofar as law professors are experts about these issues, it is instructive to discover and carefully examine what views those experts hold, so as to help determine which views are most likely to be true and how the legal academy ought to develop.

Arguments from consciousness to God’s existence (ACs) contend that physicalism is too problematic to explain the mind’s ultimate source. They add that theism probably better explains this source in terms of God making us in his own image (with conscious, unified, rational minds). But ACs are problematic too. First, physicalism has various competitors beside theism. Russellian monism and dual-aspect theory are examples. Second, all these theories, including theism, are seriously flawed. For example, it’s tied to traditional dualism, which has causal (...) issues (according to Murphy, Churchland, and other physicalists). But we argue that this theistic dualism can be refined to avoid its issues—and the issues in all other theories. So, it probably explains the mind’s origin better than other theories. We rely here on Lowe’s dualism, where the mind’s subject exists immaterially yet spatially, and is a unified, simple entity (unlike neural aggregates with their quite separate parts). This turns the tables on Churchland, Murphy, and other advocates for scientism. -/- . (shrink)

Philosophy and Phenomenological Research, EarlyView.

This chapter explains how the rise of the Mechanical philosophy during the seventeenth century contributed to the transformation of the traditional, Aristotelian schema of four causes into the dominance of efficient causation as the paradigmatic cause by the time of David Hume. But the chapter simultaneously shows that the mechanical philosophy also gave rise to a number of problems internal to it, as diagnosed by Newton and Newtonian natural philosophers, that facilitated more careful analysis of the nature of causation.

This article proves that the motion principle of philosophical physics (every thing moved is moved by another) is truly compatible with the inertia principle of mathematical physics (Newton's First Law).

In this article I examine several related views expressed by Robin Hendry concerning molecular structure, emergence and chemical bonding. There is a long-standing problem in the philosophy of chemistry arising from the fact that molecular structure cannot be strictly derived from quantum mechanics. Two or more compounds which share a molecular formula, but which differ with respect to their structures, have identical Hamiltonian operators within the quantum mechanical formalism. As a consequence, the properties of all such isomers yield precisely the (...) same calculated quantities such as their energies, dipole moments etc. The only means through which the difference between the isomers can be recovered is to build their structures into the quantum mechanical calculations, something that is carried out by the application of the Born-Oppenheimer approximation. Consequently, it has been argued by many authors that molecular structure is written in ‘by hand’ rather than derived. Robin Hendry is one such author, but he goes a great deal further by proposing that this situation implies the existence of emergence and downward causation. In the current article I argue that there are alternative explanations which render emergence and downward causation redundant. Such an alternative lies in the notion of quantum decoherence and the appeal to work in the foundations of physics, which posits that the various isomers exist as a superposition until their wavefunctions are collapsed either by observation or by interacting with their environment. Hendry also alludes to a debate among chemists as to whether chemical bonds are real or not, in the sense of directional connections between two or more nuclei in any given molecule. I reject this view and propose that the structural and energetic views of chemical bonding, that have been discussed by some philosophers of chemistry including Hendry, do not refer to any essential ontological differences. I agree that chemists view bonding in a more realistic fashion and may consider bonds to be in some senses real, while physicists may consider bonding in more abstract energetic terms. However, I do not believe that such differences in scientific practice and attitudes should be considered to offer a window as to the ontological status of bonding or whether bonding is real. Finally, I discuss the kinetic energy school of chemical bonding which would seem to challenge any notion of bonds as directional entities, since bonding is no longer regarded as being primarily due to the build-up of electron density between nuclei.

Aristotle's account of external goods in Nicomachean Ethics I 8-12 is often thought to amend his narrow claim that happiness is virtuous activity. I argue, to the contrary, that on Aristotle's account, external goods are necessary for happiness only because they are necessary for virtuous activity. My case innovates in three main respects: I offer a new map of EN I 8-12; I identify two mechanisms to explain why virtuous activity requires external goods, including a psychological need for external goods; (...) and I show the relevance of Aristotle's distinction between wishing and choosing. On the view I attribute to Aristotle, our capacity to choose virtuously requires, first, that we wish for external goods (because virtue requires the right attitudes of evaluation) and, second, that these wishes are generally fulfilled (because the social consequences and psychological pain of unfulfilled wishes undermine our opportunity to act virtuously and to take pleasure in acting virtuously). I close with discussion of how Aristotelians should defend this approach. (shrink)

A quick introduction to category theory and topos theory, axiomatically. These notes are adapted from Prof. Pettigrew’s notes.

There are many alleged problems with trusting another person’s moral testimony, perhaps the most prominent of which is that it fails to deliver moral understanding. Without moral understanding, one cannot do the right thing for the right reason, and so acting on trusted moral testimony lacks moral worth. This chapter, however, argues that moral advice differs from moral testimony, differs from it in a way that enables a defender of moral advice to parry this worry about moral worth. The basic (...) idea is that an advisor and an advisee can together constitute a joint agent, and that this joint agent’s action can indeed have moral worth. So while the advisee himself might not do the right thing for the right reason (this because all alone he lacks the right reason), and while the advisor herself might not do the right thing for the right reason (this because all alone she does not do the right thing), they together do the right for the right reason.

The open-domain Frame Problem is the problem of determining what features of an open task environment need to be updated following an action. Here we prove that the open-domain Frame Problem is equivalent to the Halting Problem and is therefore undecidable. We discuss two other open-domain problems closely related to the Frame Problem, the system identification problem and the symbol-grounding problem, and show that they are similarly undecidable. We then reformulate the Frame Problem as a quantum decision problem, and show (...) that it is undecidable by any finite quantum computer. (shrink)

The overwhelming majority of those who theorize about implicit biases posit that these biases are caused by some sort of association. However, what exactly this claim amounts to is rarely specified. In this paper, I distinguish between different understandings of association, and I argue that the crucial senses of association for elucidating implicit bias are the cognitive structure and mental process senses. A hypothesis is subsequently derived: if associations really underpin implicit biases, then implicit biases should be modulated by counterconditioning (...) or extinction but should not be modulated by rational argumentation or logical interventions. This hypothesis is false; implicit biases are not predicated on any associative structures or associative processes but instead arise because of unconscious propositionally structured beliefs. I conclude by discussing how the case study of implicit bias illuminates problems with popular dual-process models of cognitive architecture. (shrink)

This contribution unfolds an existential-ontological response to the question of sexual difference in the context of Heidegger’s formally indicative concept of “Dasein.” The question of Dasein’s “neutrality” concerns how formal indication formalizes, empties, and neutralizes the givenness of factical human existence. Ostensibly “given” biological and anthropological facts, such as sexual difference, are interpreted from an emptied and neutralized perspective that appears abstract and fictional to Heidegger’s critics. How, then, is the “neutrality” of formalizing emptying related to the “facticity” of in (...) each case factically existing as a sexual and gendered being? The answer lies in Heidegger’s elucidation of the existential-ontological structure of Dasein: Dasein is always relationally instituted in its factical entangled life through “being-with.” The sexual difference of human existence is not merely biologically or anthropologically given, but disclosed and enacted according to one’s relations with others, the environment, and oneself. The formally indicating concept “Dasein” indicates, accordingly, the concrete diversity and plurality of individuated sexual and gendered ways of being. (shrink)

I offer an interpretation of the puzzle posed by Greenberg’s failure to come to terms with the explosion of postmodernist experimentation in the 1960’s. Greenberg, one of the most influential critics of the immediately preceding period and a strong supporter of New York abstract expressionism and color field painting, is indelibly associated with modernist schools of painting. His short essay, “Modernist Painting”, valorized precisely these movements and was a tour de force catapulting Greenberg into critic superstar status; it is still (...) one of the central documents in debates about modernism. Because Greenberg there makes references to Kant’s aesthetics in identifying the virtues of modernism his account is usually interpreted in terms of the formalism of the period and Kant’s analytic of the beautiful. This offers a reading of Greenberg as a formalist and as identifying modernism with a concern for the formal properties of art, the flatness of the picture frame and the formal relations between the aesthetic properties. Greenberg was also celebrated as having a legendary acuteness of aesthetic appreciation—a critical eye penetrating immediately to a work’s aesthetic depth. (shrink)

Whole Brain Emulation has been championed as the most promising, well-defined route to achieving both human-level artificial intelligence and superintelligence. It has even been touted as a viable route to achieving immortality through brain uploading. WBE is not a fringe theory: the doctrine of Computationalism in philosophy of mind lends credence to the in-principle feasibility of the idea, and the standing of the Human Connectome Project makes it appear to be feasible in practice. Computationalism is a popular, independently plausible theory, (...) and Connectomics a well-funded empirical research program, so optimism about WBE is understandable. However, this optimism may be misplaced. This article argues that WBE is, at best, no more compelling than any of the other far-flung routes to achieving superintelligence. Similarly skeptical conclusions are found regarding immortality. The essay concludes with some positive considerations in favor of the Biological Theory of consciousness, as well as morals about the limits of Computationalism in both artificial intelligence and the philosophy of mind more generally.

We propose four policies of ethical design of human-grade Artificial Intelligence. Two of our policies are precautionary. Given substantial uncertainty both about ethical theory and about the conditions under which AI would have conscious experiences, we should be cautious in our handling of cases where different moral theories or different theories of consciousness would produce very different ethical recommendations. Two of our policies concern respect and freedom. If we design AI that deserves moral consideration equivalent to that of human beings, (...) that AI should be designed with self-respect and with the freedom to explore values other than those we might impose. We are especially concerned about the temptation to create human-grade AI pre-installed with the desire to cheerfully sacrifice itself for its creators’ benefit. (shrink)

“What is the structure of thought?” is as central a question as any in cognitive science. A classic answer to this question has appealed to a Language of Thought (LoT). We point to emerging research from disparate branches of the field that supports the LoT hypothesis, but also uncovers diversity in LoTs across cognitive systems, stages of development, and species. Our letter formulates open research questions for cognitive science concerning the varieties of rules and representations that underwrite various LoT-based systems (...) and how these variations can help researchers taxonomize cognitive systems.

In some recent works, Crupi and Iacona have outlined an analysis of ‘if’ based on Chrysippus’ idea that a conditional holds whenever the negation of its consequent is incompatible with its antecedent. This paper presents a sound and complete system of conditional logic that accommodates their analysis. The soundness and completeness proofs that will be provided rely on a general method elaborated by Raidl, which applies to a wide range of systems of conditional logic.

Many philosophers maintain that causation is to be explicated in terms of a kind of dependence between cause and effect. These “dependence” theories are opposed by “production” accounts which hold that there is some more fundamental causal “oomph”. A wide range of experimental research on everyday causal judgments seems to indicate that ordinary people operate primarily with a dependence-based notion of causation. For example, people tend to say that absences and double preventers are causes. We argue that the impression that (...) commonsense causal discourse is largely dependence-based is the result of focusing on a very narrow class of causal verbs. Almost all of the vignette-based experimental work on causal judgment has been prosecuted using the word “cause”. But much ordinary causal discourse involves special causal verbs, such as “burn” and “crack”. We find that these verbs display a quite different pattern from the verb “cause”. For instance, for absences and double preventers (Studies 1-3), we find that while people are inclined to say that X caused Y to burn, turn, crack or start, they are less inclined to think that X burned, turned, cracked or started Y. In Study 4, we find that for chains involving a distal and proximal event, people are inclined to say that the distal event is not a special cause of the outcome, though it is a “cause” of the outcome. Together, we find a surprising double dissociation between “cause” and a stock of special causal verbs. We conclude by suggesting that much commonsense causal judgment, which heavily trades in special causal verbs, might be better captured by production-based accounts of causation. (shrink)

A Bayesian mind is, at its core, a rational mind. Bayesianism is thus well-suited to predict and explain mental processes that best exemplify our ability to be rational. However, evidence from belief acquisition and change appears to show that we do not acquire and update information in a Bayesian way. Instead, the principles of belief acquisition and updating seem grounded in maintaining a psychological immune system rather than in approximating a Bayesian processor.

After presenting evidence about categorization behavior, this paper argues for the following theses: 1) that there is a border between perception and cognition; 2) that the border is to be characterized by perception being modular (and cognition not being so); 3) that perception outputs conceptualized representations, so views that posit that the output of perception is solely non-conceptual are false; and 4) that perceptual content consists of basic-level categories and not richer contents.

An analysis of a valenced corpus of English words revealed that words that rhyme with slurs are rated more poorly than their synonyms. What at first might seem like a bizarre coincidence turns out to be a robust feature of slurs, one arising from their phonetic structure. We report novel data on phonaesthetic preferences, showing that a particular class of phonemes are both particularly disliked, and overrepresented in slurs. We argue that phonaesthetic associations have been an overlooked source of some (...) of the more peculiar, arational aspects of slurs. We conclude by drawing broader morals about the evolution of the lexicon. (shrink)

Foundational theories of mental content seek to identify the conditions under which a mental representation expresses, in the mind of a particular thinker, a particular content. Normativists endorse the following general sort of foundational theory of mental content: A mental representation r expresses concept C for agent S just in case S ought to use r in conformity with some particular pattern of use associated with C. In response to Normativist theories of content, Kathrin Glüer-Pagin and Åsa Wikforss propose a (...) dilemma, alleging that Normativism either entails a vicious regress or falls prey to a charge of idleness. In this paper, I respond to this argument. I argue that Normativism can avoid the commitments that generate the regress and does not propose the sort of explanation required to charge that its explanation has been shown to be problematically idle. The regress-generating commitment to be avoided is, roughly, that tokened, contentful mental states are the product of rule-following. The explanatory task Normativists should disavow is that of explaining how it is that beliefs and other contentful mental states are produced. I argue that Normativism, properly understood as a theory of content, does not provide this kind of psychological explanation, and therefore does not entail that such explanations are to be given in terms of rule-following. If this is correct, Normativism is not the proper target of the dilemma offered by Glüer-Pagin and Wikforss. Understanding why one might construe Normativism in the way Glüer-Pagin and Wikforss must, and how, properly understood, it avoids their dilemma, can help us to appreciate the attractiveness of a genuinely normative theory of content and the importance of paying careful attention to the sort of normativity involved in norm-based theories of content.

What is the source of aesthetic knowledge? Empirical knowledge, it is generally held, bottoms out in perception. Such knowledge can be transmitted to others through testimony, preserved by memory, and amplified via inference. But perception is where the rubber hits the road. What about aesthetic knowledge? Does it too bottom out in perception? Most say “yes”. But this is wrong. When it comes to aesthetic knowledge, it is appreciation, not perception, where the rubber hits the road. The ultimate source of (...) aesthetic knowledge is feeling. In this essay, we articulate and defend the very idea of affective knowledge and reveal aesthetic knowledge to be a species of the genus. We then show how the view resolves a thorny problem that has bedeviled aesthetic epistemologists: how to reconcile the seemingly direct character of aesthetic knowledge with the possibility of acquiring such knowledge from criticism. One learns from criticism, we argue, when it guides one’s engagement with an object so that one can appreciate it in virtue of those of its features that render it worthy of appreciation. (shrink)

Number words seemingly function both as adjectives attributing cardinality properties to collections, as in Frege’s ‘Jupiter has four moons’, and as names referring to numbers, as in Frege’s ‘The number of Jupiter’s moons is four’. This leads to what Thomas Hofweber calls Frege’s Other Puzzle: How can number words function as modifiers and as singular terms if neither adjectives nor names can serve multiple semantic functions? Whereas most philosophers deny that one of these uses is genuine, we instead argue that (...) number words, like many related expressions, are polymorphic, having multiple uses whose meanings are systematically related via type shifting.

What did Heidegger learn and fail to learn from Laozi and Zhuangzi? This book reconstructs Heidegger's philosophy through its engagement with Daoist and Asian philosophy and offers a Daoist transformation of Heidegger on things, nothingness, and freedom.

On an intellectualist approach to belief, the intellectual endorsement of a proposition (such as “The working poor deserve as much respect as the handsomely paid”) is sufficient or nearly sufficient for believing it. On a pragmatic approach to belief, intellectual endorsement is not enough. Belief is behaviorally demanding. To really, fully believe, you must also “walk the walk.” This chapter argues that the pragmatic approach is preferable on pragmatic grounds: It rightly directs our attention to what matters most in thinking (...) about belief.

Do university ethics classes influence students’ real-world moral choices? We aimed to conduct the first controlled study of the effects of ordinary philosophical ethics classes on real-world moral choices, using non-self-report, non-laboratory behavior as the dependent measure. We assigned 1332 students in four large philosophy classes to either an experimental group on the ethics of eating meat or a control group on the ethics of charitable giving. Students in each group read a philosophy article on their assigned topic and optionally (...) viewed a related video, then met with teaching assistants for 50-minute group discussion sections. They expressed their opinions about meat ethics and charitable giving in a follow-up questionnaire (1032 respondents after exclusions). We obtained 13,642 food purchase receipts from campus restaurants for 495 of the students, before and after the intervention. Purchase of meat products declined in the experimental group (52% of purchases of at least $4.99 contained meat before the intervention, compared to 45% after) but remained the same in the control group (52% both before and after). Ethical opinion also differed, with 43% of students in the experimental group agreeing that eating the meat of factory farmed animals is unethical compared to 29% in the control group. We also attempted to measure food choice using vouchers, but voucher redemption rates were low and no effect was statistically detectable. It remains unclear what aspect of instruction influenced behavior. (shrink)

Moorean arguments are a popular and powerful way to engage highly revisionary philosophical views, such as nihilism about motion, time, truth, consciousness, causation, and various kinds of skepticism (e.g., external world, other minds, inductive, global). They take, as a premise, a highly plausible first-order claim (e.g., cars move, I ate breakfast before lunch, it’s true that some fish have gills) and conclude from it the falsity of the highly revisionary philosophical thesis. Moorean arguments can be used against nihilists in ethics (...) (error theorists), too. Recently, error theorists have recognized Moorean arguments as a powerful challenge and have tried to meet it. They’ve argued that moral Moorean premises seem highly credible to us, but aren’t, by offering various debunking explanations. These explanations all appeal to higher-order evidence—evidence of error in our reasoning. I argue that drawing attention to higher-order evidence is a welcome contribution from error theorists, but that the higher-order evidence actually counts further against error theoretic arguments—including their debunking explanations—and further in favor of Moorean arguments and the commonsense views they support. Along the way I answer a few prominent objections to Moorean arguments: that they are objectionably question-begging, rely on categorizing some facts as “Moorean Facts”, and that reports of one’s credence in a proposition bears no interesting relation to that proposition’s credibility.

This essay attempts to clarify the nature and structure of aliefs. First I distinguish between a robust notion of aliefs and a deflated one. A robust notion of aliefs would introduce aliefs into our psychological ontology as a hitherto undiscovered kind, whereas a deflated notion of aliefs would identify aliefs as a set of pre-existing psychological states. I then propose the following dilemma: one the one hand, if aliefs have propositional content, then it is unclear exactly how aliefs differ from (...) psychological states we already countenance, in which case there is no robust notion of aliefs; on the other, if aliefs just contain associative content, then they cannot do the explanatory work set out for them, in which case there is no reason to posit aliefs at all. Thus, it appears that we have little reason to posit the novel category of robust aliefs. (shrink)

Consider the following three claims. (i) There are no truths of the form ‘p and ~p’. (ii) No one holds a belief of the form ‘p and ~p’. (iii) No one holds any pairs of beliefs of the form {p, ~p}. Irad Kimhi has recently argued, in effect, that each of these claims holds and holds with metaphysical necessity. Furthermore, he maintains that they are ultimately not distinct claims at all, but the same claim formulated in different ways. I find (...) his argument suggestive, if not entirely transparent. I do think there is at least an important kernel of truth even in (iii), and that (i) ultimately explains what’s right about the other two. Consciousness of an impossibility makes belief in the obtaining of the corresponding state of affairs an impossibility. Interestingly, an appreciation of this fact brings into view a novel conception of inference, according to which it consists in the consciousness of necessity. This essay outlines and defends this position. A central element of the defense is that it reveals how reasoners satisfy what Paul Boghossian calls the Taking Condition and do so without engendering regress. (shrink)

I follow standard mathematical practice and theory to argue that the natural numbers are the finite von Neumann ordinals.

I give a detailed mathematical demonstration that 0 is { } and for every natural number n, n is the set of all natural (...) numbers less than n. Natural numbers are sets.
