The personal identity relation is of great interest to philosophers, who often consider fictional scenarios to test what features seem to make persons persist through time. But often real examples of neuroscientific interest also provide important tests of personal identity. One such example is the case of Phineas Gage – or at least the story often told about Phineas Gage. Many cite Gage’s story as example of severed personal identity; Phineas underwent such a tremendous change that Gage “survived as a (...) different man.” I discuss a recent empirical finding about judgments about this hypothetical. It is not just the magnitude of the change that affects identity judgment; it is also the negative direction of the change. I present an experiment suggesting that direction of change also affects neuroethical judgments. I conclude we should consider carefully the way in which improvements and deteriorations affect attributions of personal identity. This is particularly important since a number of the most crucial neuroethical decisions involve varieties of cognitive enhancements or deteriorations. (shrink)

“Experimental jurisprudence” draws on empirical data to inform questions typically associated with jurisprudence or legal theory. Scholars in this flourishing movement conduct empirical studies about a variety of legal language and concepts. Despite the movement’s growth, its justification is still opaque. Jurisprudence is the study of deep and longstanding theoretical questions about law’s nature, but “experimental jurisprudence,” it might seem, simply surveys laypeople. This Article elaborates and defends experimental jurisprudence. Experimental jurisprudence, appropriately understood, is not only consistent with traditional jurisprudence; (...) it is an essential branch of it. (shrink)

Most plausible moral theories must address problems of partial acceptance or partial compliance. The aim of this paper is to examine some proposed ways of dealing with partial acceptance problems as well as to introduce a new Rule Utilitarian suggestion. Here I survey three forms of Rule Utilitarianism, each of which represents a distinct approach to solving partial acceptance issues. I examine Fixed Rate, Variable Rate, and Optimum Rate Rule Utilitarianism, and argue that a new approach, Maximizing Expectation Rate Rule (...) Utilitarianism, better solves partial acceptance problems. (shrink)

Many philosophers claim to employ intuitions in their philosophical arguments. Others contest that no such intuitions are used frequently or at all in philosophy. This article suggests and defends a conception of intuitions as part of the philosophical method: intuitions are special types of philosophical assumptions to which we are invited to assent, often as premises in argument, that may serve an independent function in philosophical argument and that are not formed through a purely inferential process. A series of philosophical (...) case studies shows that intuitions in these arguments contain the relevant features. The view has implications for philosophical method, offering a compromise between opponents on the divisive debate of the merits of experimental philosophy: experimental philosophy provides an especially useful role in philosophical assumption analysis.

Two separate research programs have revealed two different factors that feature in our judgments of whether some entity persists. One program—inspired by Knobe—has found that normative considerations affect persistence judgments. For instance, people are more inclined to view a thing as persisting when the changes it undergoes lead to improvements. The other program—inspired by Kelemen—has found that teleological considerations affect persistence judgments. For instance, people are more inclined to view a thing as persisting when it preserves its purpose. Our goal (...) in this paper is to determine what causes persistence judgments. Across four studies, we pit normative considerations against teleological considerations. And using causal modeling procedures, we find a consistent, robust pattern with teleological and not normative considerations directly causing persistence judgments. Our findings put teleology in the driver’s seat, while at the same time shedding further light on our folk notion of an object. (shrink)

Scalar Utilitarianism eschews foundational notions of rightness and wrongness in favor of evaluative comparisons of outcomes. I defend Scalar Utilitarianism from two critiques, the first against an argument for the thesis that Utilitarianism's commitments are fundamentally evaluative, and the second that Scalar Utilitarianism does not issue demands or sufficiently guide action. These defenses suggest a variety of more plausible Scalar Utilitarian interpretations, and I argue for a version that best represents a moral theory founded on evaluative notions, and offers better (...) answers to demandingness concerns than does the ordinary Scalar Utilitarian response. If Utilitarians seek reasonable development and explanation of their basic commitments, they may wish to reconsider Scalar Utilitarianism. (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.

What constitutes a “good” life—not necessarily a morally good life, but a life that is good for the person who lived it? In response to this question of “well-being," philosophers have offered three significant answers: A good life is one in which a person can satisfy their desires (“Desire-Satisfaction” or “Preferentism”), one that includes certain good features (“Objectivism”), or one in which pleasurable states dominate or outweigh painful ones (“Hedonism”). To adjudicate among these competing theories, moral philosophers traditionally gather data (...) from thought experiments and intuition. In this chapter, we supplement that traditional approach with a pair of experimental studies that examine whether the three theories reflect laypeople’s intuitions about well-being. The empirical studies yield two primary findings. First, they provide evidence for lay "well-being pluralism": laypeople treat desire satisfaction, positive objective conditions, and happiness as all constitutive of well-being. Second, the studies provide evidence of "hedonic dominance": laypeople evaluate an individual’s happiness as more important to an individual’s overall well-being than desire satisfaction or objective conditions.

This study aims to generate thorough and comprehensive review of the teacher’s perspective and hands-on experience in mainstreaming LSENs in a regular classroom, including teachers’ attitudes and perceptions, challenges encountered, and teaching approach in handling mainstreamed classrooms. A scoping review framework by Arksey and O’Malley’s (2005) systematically analyzed the data of the different articles conducted by various scholars. Through scrupulous and through selection of related studies, 10 articles were included in the review from 6 different countries across the globe. The (...) articles included were conducted from 6 countries and various databases. The study highlighted that: 1) teachers have positive and negative attitudes towards mainstreaming, 2) teachers experienced various challenges in handling a mainstream classroom, and 3) learner-centered approach to learning is used in the classroom. Mainstreaming LSENs in a regular classroom has pros and cons among teachers, regular students, and the LSENs themselves. Hence, a daunting responsibility for the teachers. Nevertheless, it is imperative to support teachers by giving seminars and training, especially to those non-special education majors, to be fully equipped to handle mainstreamed classrooms. (shrink)

According to Phenomenal Conservatism (PC), if a subject S has an appearance that P, in the absence of defeaters, S has justification for believing P by virtue of her appearance's inherent justifying power. McCain and Moretti (2021) have argued that PC is affected by the problem of reflective awareness: if S becomes reflectively aware of an appearance, the appearance loses its inherent justifying power. This limits the explanatory power of PC and reduces its antisceptical bite. This paper provides a novel (...) argument to the same conclusion and contends that it does not apply to Phenomenal Explanationism, the appearance-based account of justification alternative to PC defended by McCain and Moretti (2021).

The Lockean Thesis says that you must believe p iff you’re sufficiently confident of it. On some versions, the 'must' asserts a metaphysical connection; on others, it asserts a normative one. On some versions, 'sufficiently confident' refers to a fixed threshold of credence; on others, it varies with proposition and context. Claim: the Lockean Thesis follows from epistemic utility theory—the view that rational requirements are constrained by the norm to promote accuracy. Different versions of this theory generate different versions of (...) Lockeanism; moreover, a plausible version of epistemic utility theory meshes with natural language considerations, yielding a new Lockean picture that helps to model and explain the role of beliefs in inquiry and conversation. Your beliefs are your best guesses in response to the epistemic priorities of your context. Upshot: we have a new approach to the epistemology and semantics of belief. And it has teeth. It implies that the role of beliefs is fundamentally different than many have thought, and in fact supports a metaphysical reduction of belief to credence. (shrink)

We have been observing how infants between 3 and 21 months react when a vibrotactile stimulation (a buzzer) is applied to different parts of their bodies. Responses included in particular movement of the stimulated body part and successful reaching for and removal of the buzzer. Overall, there is a pronounced developmental progression from general to specific movement patterns, especially in the first year. In this article we review the series of studies we conducted and then focus on possible mechanisms that (...) might explain what we observed. One possible mechanism might rely on the brain extracting “sensorimotor contingencies” linking motor actions and resulting sensory consequences. This account posits that infants are driven by intrinsic motivation that guides exploratory motor activity, at first generating random motor babbling with self-touch occurring spontaneously. Later goal-oriented motor behavior occurs, with self-touch as a possible effective tool to induce informative contingencies. We connect this sensorimotor view with a second possible account that appeals to the neuroscientific concepts of cortical maps and coordinate transformations. In this second account, the improvement of reaching precision is mediated by refinement of neuronal maps in primary sensory and motor cortices—the homunculi—as well as in frontal and parietal corti- cal regions dedicated to sensorimotor processing. We complement this theoretical account with modeling on a humanoid robot with artificial skin where we implemented reaching for tactile stimuli as well as learning the “somatosensory homunculi”. We suggest that this account can be extended to reflect the driving role of sensorimotor contingencies in human development. In our conclusion we consider possible extensions of our current experiments which take account of predictions derived from both these kinds of models. (shrink)

KK is the thesis that if you can know p, you can know that you can know p. Though it’s unpopular, a flurry of considerations has recently emerged in its favour. Here we add fuel to the fire: standard resources allow us to show that any failure of KK will lead to the knowability and assertability of abominable indicative conditionals of the form ‘If I don’t know it, p’. Such conditionals are manifestly not assertable—a fact that KK defenders can easily (...) explain. I survey a variety of KK-denying responses and find them wanting. Those who object to the knowability of such conditionals must either deny the possibility of harmony between knowledge and belief, or deny well-supported connections between conditional and unconditional attitudes. Meanwhile, those who grant knowability owe us an explanation of such conditionals’ unassertability—yet no successful explanations are on offer. Upshot: we have new evidence for KK. (shrink)

This paper is a study about Philadelphia’s comprehensive user engagement sites (CUESs) as the authors address and examine issues related to the upcoming implementation of a CUES while seeking solutions for its disputed questions and plans. Beginning with the federal drug schedules, the authors visit some of the medical and public health issues vis-à-vis safe injection facilities (SIFs). Insite, a successful Canadian SIF, has been thoroughly researched as it represents a paradigm for which a Philadelphia CUES can expand upon. Also, (...) the existing criticisms against SIFs are revisited while critically unpackaged and responded to in favor of the establishment. In the main section, the authors propose the layout and services of the upcoming CUES, much of which would be in congruent to Vancouver’s Insite. On the other hand, the CUES would be distinct from Insite, as the authors emphasize, in that it will offer an information center run by individuals in recovery and place additional emphasis on early education for young healthcare professionals by providing them a platform to work at the site. The paper will also briefly investigate the implementation of a CUES site under an ethical scope of the Harm Reduction Theory. Lastly, the authors recommend some strategic plans that the Philadelphia City government may consider employing at this crucial stage. (shrink)

It is common to think that grounding is necessary in the sense that: if P grounds Q, then necessarily: if P, then Q. Though most accept this principle, some give counterexamples to it. Instead of straightforwardly arguing for, or against, necessity, I explain the sense in which grounding is necessary and contingent. I argue that there are two kinds of grounding: what-grounding and why-grounding, where the former kind is necessary while the latter is contingent.

A prevalent assumption among philosophers who believe that people can intentionally deceive themselves (intentionalists) is that they accomplish this by controlling what evidence they attend to. This article is concerned primarily with the evaluation of this claim, which we may call ‘attentionalism’. According to attentionalism, when one justifiably believes/suspects that not-p but wishes to make oneself believe that p, one may do this by shifting attention away from the considerations supportive of the belief that not-p and onto considerations supportive of (...) the belief that p. The details of this theory are elaborated, its theoretical importance is pointed out, and it is argued that the strategy is supposed to work by leading to the repression of one’s knowledge of the unwelcome considerations. However, I then show that the assumption that this is possible is opposed by the balance of a relevant body of empirical research, namely, the thought-suppression literature, and so intentionalism about self-deception cannot find vindication in the attentional theory.

This article discusses a kind of knowledge classifiable as knowledge-wh but which seems to defy analysis in terms of the standard reductive theory of knowledge-wh ascriptions, according to which they are true if and only if one knows that p, where this proposition is an acceptable answer to the wh-question ‘embedded’ in the ascription. Specifically, it is argued that certain cases of knowing what an experience is like resist such treatment. I argue that in some of these cases, one can (...) know that p, where an acceptable answer to the question ‘What’s the experience like?’ is that p, but where one does not know what the experience is like. This could point to the distinctiveness of this sort of knowledge. (shrink)

The Knowledge Norm of Assertion claims that it is proper to assert that p only if one knows that p. Though supported by a wide range of evidence, it appears to generate incorrect verdicts when applied to utterances of “I don't know.” Instead of being an objection to KNA, I argue that this linguistic data shows that “I don't know” does not standardly function as a literal assertion about one's epistemic status; rather, it is an indirect speech act that has (...) the primary illocutionary force of opting out of the speaker's conversational responsibilities. This explanation both reveals that the opt-out is an under-appreciated type of illocutionary act with a wide range of applications, and shows that the initial data in fact supports KNA over its rivals.

In their correspondence in 1902 and 1903, after discussing the Russell paradox, Russell and Frege discussed the paradox of propositions considered informally in Appendix B of Russell’s Principles of Mathematics. It seems that the proposition, p, stating the logical product of the class w, namely, the class of all propositions stating the logical product of a class they are not in, is in w if and only if it is not. Frege believed that this paradox was avoided within his philosophy (...) due to his distinction between sense (Sinn) and reference (Bedeutung). However, I show that while the paradox as Russell formulates it is ill-formed with Frege’s extant logical system, if Frege’s system is expanded to contain the commitments of his philosophy of language, an analogue of this paradox is formulable. This and other concerns in Fregean intensional logic are discussed, and it is discovered that Frege’s logical system, even without its naive class theory embodied in its infamous Basic Law V, leads to inconsistencies when the theory of sense and reference is axiomatized therein.

The COVID-19 outbreak had a profound impact on many facets of society, particularly on the educational system. Therefore, all educational content must be delivered to students online, and it is the student’s responsibility to adjust to this new norm. Hence, this study sought to investigate if there is a significant relationship between self-efficacy and resilience among senior high school students. This study utilized correlational research, with the 150 grade 12 senior high school students enrolled in 2022-2023 as respondents. Thus, the (...) researchers employed General Self-Efficacy and Resilience Scale. Finally, the statistical analysis reveals that the r coefficient of 0.53 indicates a moderate positive correlation between the variables. The p-value of 0.00, less than 0.05, leads to rejecting the null hypothesis. Hence, a significant relationship exists between self-efficacy and resilience among senior high school students. (shrink)

Is epistemic inconsistency a mere symptom of having violated other requirements of rationality—notably, reasons-responsiveness requirements? Or is inconsistency irrational on its own? This question has important implications for the debate on the normativity of epistemic rationality. In this paper, I defend a new account of the explanatory role of the requirement of epistemic consistency. Roughly, I will argue that, in cases where an epistemically rational agent is permitted to believe P and also permitted to disbelieve P, the consistency requirement plays (...) a distinct explanatory role. I will also argue that such a type of permissiveness is a live possibility when it comes to rational epistemic standards. (shrink)

It has been argued that an epistemically rational agent’s evidence is subjectively mediated through some rational epistemic standards, and that there are incompatible but equally rational epistemic standards available to agents. This supports Permissiveness, the view according to which one or multiple fully rational agents are permitted to take distinct incompatible doxastic attitudes towards P (relative to a body of evidence). In this paper, I argue that the above claims entail the existence of a unique and more reliable epistemic standard. (...) My strategy relies on Condorcet’s Jury Theorem. This gives rise to an important problem for those who argue that epistemic standards are permissive, since the reliability criterion is incompatible with such a type of Permissiveness. (shrink)

Review of Basic Laws of Arithmetic, ed. and trans. by P. Ebert and M. Rossberg (Oxford 2013).

What is the relationship between Immodesty and Permissivism? For permissivists, epistemically rational agents are sometimes permitted to take incompatible doxastic attitudes towards P. Immodesty is a requirement governing our estimations or beliefs about our own credences and standards. If agents believe that their standards and credences are not among the most truth-conducive ones available to them, they are not immodest. Some philosophers think that Immodesty is incompatible with Intrapersonal Permissivism :41–56, 2014, J Philos 116:237–262, 2019). Others think that Immodesty can (...) be used to respond to some objections against Interpersonal Permissivism :193–218). In this paper, we argue that Immodesty neither supports nor disproves Permissivism. (shrink)

Many philosophers have offered arguments in favor of the following three theses: A is epistemically permitted to believe P only if A is in a position to know that P, incoherent agents fail to satisfy the aforementioned knowledge norm of belief, and A’s apparent reasons are relevant to determining what A is blameworthy for believing. In this paper, I argue that the above three theses are jointly inconsistent. The main upshot of the paper is this: even if the knowledge norm (...) of belief is correct, it cannot explain some deontic requirements governing belief. (shrink)

This paper develops a problem for conciliationism that is structurally similar to the self-undermining problem but which is immune to most of the solutions offered against it. A popular objection to conciliationism is that it undermines itself. Given the current disagreement among philosophers about conciliationism, conciliationism seems to require rejecting conciliationism. Adam Elga (2010) has influentially argued that this shows that conciliationism is an incoherent method. By recommending its own rejection, conciliationism recommends multiple, incompatible responses to the same body of (...) experience. Many have offered solutions to this problem, including Elga himself. However, there is another undermining problem. When a peer disagrees about their own peerhood, conciliationism can require the rejection of the peer’s peerhood. The result is that conciliationism recommends two incompatible responses to the same body of experience in a way that parallels the original self-undermining problem. But since many, if not all, of the proposed solutions to the original undermining problem depend on distinctive characteristics of conciliationism undermining itself, they cannot apply to a peer undermining themself. I illustrate this by dividing the solutions that have been offered against the self-undermining problem into two categories: self-exempting solutions and non-exempting solutions. I then show how the proposed solutions under each type do not extend to the peer-undermining problem. If that is right, then conciliationism is faced with a more difficult undermining problem than has been so far acknowledged. (shrink)

Some argue that robots could never be sentient, and thus could never have intrinsic moral status. Others disagree, believing that robots indeed will be sentient and thus will have moral status. But a third group thinks that, even if robots could never have moral status, we still have a strong moral reason to treat some robots as if they do. Drawing on a Kantian argument for indirect animal rights, a number of technology ethicists contend that our treatment of anthropomorphic or (...) even animal-like robots could condition our treatment of humans: treat these robots well, as we would treat humans, or else risk eroding good moral behavior toward humans. But then, this argument also seems to justify giving rights to robots, even if robots lack intrinsic moral status. In recent years, however, this indirect argument in support of robot rights has drawn a number of objections. In this paper I have three goals. First, I will formulate and explicate the Kant-inspired indirect argument meant to support robot rights, making clearer than before its empirical commitments and philosophical presuppositions. Second, I will defend the argument against a number of objections. The result is the fullest explication and defense to date of this well-known and influential but often criticized argument. Third, however, I myself will raise a new concern about the argument’s use as a justification for robot rights. This concern is answerable to some extent, but it cannot be dismissed fully. It shows that, surprisingly, the argument’s advocates have reason to resist, at least somewhat, producing the sorts of robots that, on their view, ought to receive rights. (shrink)

Experimental philosophy of consciousness aims to investigate and explain our thinking about phenomenally conscious states. Based on empirical studies, researchers have argued (a) that we lack a folk concept of consciousness, (b) that we do not think entities like Microsoft feel regret, (c) that unfelt pains are widely accepted, and (d) that people do not attribute phenomenally conscious states to duplicated hamsters. In this article, I review these and other intriguing claims about people’s understanding of phenomenal consciousness. In doing so, (...) I also show why experimental philosophy of consciousness is challenging, although perhaps not quite as daunting as studying phenomenal consciousness itself. (shrink)

Alfred Mele's deflationary account of self-deception has frequently been criticised for being unable to explain the “tension” inherent in self-deception. These critics maintain that rival theories can better account for this tension, such as theories which suppose self-deceivers to have contradictory beliefs. However, there are two ways in which the tension idea has been understood. In this article, it is argued that on one such understanding, Mele's deflationism can account for this tension better than its rivals, but only if we (...) reconceptualize the self-deceiver's attitude in terms of unwarranted degrees of conviction rather than unwarranted belief. This new way of viewing the self-deceiver's attitude will be informed by observations on experimental work done on the biasing influence of desire on belief, which suggests that self-deceivers don’t manage to fully convince themselves of what they want to be true. On another way in which this tension has been understood, this account would not manage so well, since on this understanding the self-deceiver is best interpreted as knowing, but wishing to avoid, the truth. However, it is argued that we are under no obligation to account for this since it is a characteristic of a different phenomenon than self-deception, namely, escapism. (shrink)

You can perceive things, in many respects, as they really are. For example, you can correctly see a coin as circular from most angles. Nonetheless, your perception of the world is perspectival. The coin looks different when slanted than when head-on, and there is some respect in which the slanted coin looks similar to a head-on ellipse. Many hold that perception is perspectival because you perceive certain properties that correspond to the “looks” of things. I argue that this view is (...) misguided. I consider the two standard versions of this view. What I call the PLURALIST APPROACH fails to give a unified account of the perspectival character of perception, while what I call the PERSPECTIVAL PROPERTIES APPROACH violates central commitments of contemporary psychology. I propose instead that perception is perspectival because of the way perceptual states are structured from their parts. (shrink)

Through a series of empirical studies involving native speakers of English, German, and Chinese, this paper reveals that the predicate “true” is inherently ambiguous in the empirical domain. Truth statements such as “It is true that Tom is at the party” seem to be ambivalent between two readings. On the first reading, the statement means “Reality is such that Tom is at the party.” On the second reading, the statement means “According to what X believes, Tom is at the party.” (...) While there appear to exist some cross-cultural differences in the interpretation of the statements, the overall findings robustly indicate that “true” has multiple meanings in the realm of empirical matters.

Are acts of violence performed in virtual environments ever morally wrong, even when no other persons are affected? While some such acts surely reflect deficient moral character, I focus on the moral rightness or wrongness of acts. Typically it’s thought that, on Kant’s moral theory, an act of virtual violence is morally wrong (i.e., violate the Categorical Imperative) only if the act mistreats another person. But I argue that, on Kant’s moral theory, some acts of virtual violence can be morally (...) wrong, even when no other persons or their avatars are affected. First, I explain why many have thought that, in general on Kant’s moral theory, virtual acts affecting no other persons or their avatars can’t violate the Categorical Imperative. For there are real world acts that clearly do, but it seems that when we consider the same sorts of acts done alone in a virtual environment, they don’t violate the Categorical Imperative, because no others persons were involved. But then, how could any virtual acts like these, that affect no other persons or their avatars, violate the Categorical Imperative? I then argue that there indeed can be such cases of morally wrong virtual acts—some due to an actor’s having erroneous beliefs about morally relevant facts, and others due not to error, but to the actor’s intention leaving out morally relevant facts while immersed in a virtual environment. I conclude by considering some implications of my arguments for both our present technological context as well as the future. (shrink)

Matthew McGrath has recently challenged all theories that allow for immediate perceptual justification. This challenge comes by way of arguing for what he calls the “Looks View” of visual justification, which entails that our visual beliefs that are allegedly immediately justified are in fact mediately justified based on our independent beliefs about the looks of things. This paper shows that McGrath’s arguments are unsound or, at the very least, that they do not cause genuine concern for the species of dogmatism (...) called “Phenomenal Explanationism”, recently introduced and defended by Kevin McCain and Luca Moretti.

This chapter explores the metaphysical views about higher-order logic held by two individuals responsible for introducing it to philosophy: Gottlob Frege (1848–1925) and Bertrand Russell (1872–1970). Frege understood a function at first as the remainder of the content of a proposition when one component was taken out or seen as replaceable by others, and later as a mapping between objects. His logic employed second-order quantifiers ranging over such functions, and he saw a deep division in nature between objects and functions. (...) Russell understood propositional functions as what is obtained when constituents of propositions are replaced by variables, but eventually denied that they were entities in their own right. Both encountered contradictions when supposing there to exist as many objects as functions, and both adopted views about the meaningfulness of higher-order discourse that were difficult to state from within their own strictures.

Predictable polarization is everywhere: we can often predict how people’s opinions, including our own, will shift over time. Extant theories either neglect the fact that we can predict our own polarization, or explain it through irrational mechanisms. They needn’t. Empirical studies suggest that polarization is predictable when evidence is ambiguous, that is, when the rational response is not obvious. I show how Bayesians should model such ambiguity and then prove that—assuming rational updates are those which obey the value of evidence—ambiguity (...) is necessary and sufficient for the rationality of predictable polarization. The main theoretical result is that there can be a series of such updates, each of which is individually expected to make you more accurate, but which together will predictably polarize you. Polarization results from asymmetric increases in accuracy. This mechanism is not only theoretically possible, but empirically plausible. I argue that cognitive search—searching a cognitively accessible space for a particular item—often yields asymmetrically ambiguous evidence, I present an experiment supporting its polarizing effects, and I use simulations to show how it can explain two of the core causes of polarization: confirmation bias and the group polarization effect.

Along with offering an historically-oriented interpretive reconstruction of the syntax of PM ( rst ed.), I argue for a certain understanding of its use of propositional function abstracts formed by placing a circum ex on a variable. I argue that this notation is used in PM only when de nitions are stated schematically in the metalanguage, and in argument-position when higher-type variables are involved. My aim throughout is to explain how the usage of function abstracts as “terms” (loosely speaking) is (...) not inconsistent with a philosophy of types that does not think of propositional functions as mind- and language-independent objects, and adopts a nominalist/substitutional semantics instead. I contrast PM’s approach here both to function abstraction found in the typed λ-calculus, and also to Frege’s notation for functions of various levels that forgoes abstracts altogether, between which it is a kind of intermediary.

The paper seeks to develop an account of indexical phenomena based on the highly general theory of structure and dependence set forth by Husserl in his Logical Investigations. Husserl here defends an Aristotelian theory of meaning, viewing meanings as species or universals having as their instances certain sorts of concrete meaning acts. Indexical phenomena are seen to involve the combination of such acts of meaning with acts of perception, a thesis here developed in some detail and contrasted with accounts of (...) indexicals suggested by Frege, Wittgenstein and by the later Husserl himself in his Ideas I. Implications are drawn also for our understanding of the categorial grammar sketched by Husserl in his 4th Logical Investigation, as also for our understanding of the nature of proper names and other candidate indexical expressions.

One version of moral error theory maintains that the central problem with morality is an ontological commitment to irreducible normativity. This paper argues that this version of error theory ultimately depends on an appeal to Ockham’s Razor, and that Ockham’s Razor should not be applied to irreducible normativity. This is because the appeal to Ockham’s Razor always contains an intractable element of epistemic circularity; and if this circularity is not vicious, we can construct a sound argument for the existence of (...) irreducibly normative truths that contains a similar kind of epistemic circularity. This argument is a version of Pascal’s Wager which I call “Parfit’s Wager,” because it is based on a passage from Derek Parfit’s On What Matters. It states that, if we believe that there are some irreducibly normative truths, we are more likely to be believing what we ought to believe compared to not believing that there are such truths, and that this indicates that we ought rationally to believe that there are such truths, justifying the ontological commitment to irreducible normativity in the process.

The dominant position in current debates on the mind-body problem is some version of physicalism, according to which the mind is reducible to the brain and mental phenomena are ultimately explainable in physical terms. But there seems to be an explanatory gap between physicalistic descriptions of neuronal processes and the subjectivity of conscious experience. Some dualists conclude that, therefore, consciousness must be ontologically distinct from any physical properties or entities. This article introduces and argues for a different perspective on these (...) issues, namely, an epistemological dualism - a nonreductive position which is neither a version of physicalism nor an ontological dualism. It is argued that Kant holds this epistemological dualism implicitly as a consequence of his critical epistemology. On the one hand, he stresses the explanatory gap between the mental and the physical. On the basis of his theory of subjectivity set out in the Transcendental Deduction, Kant provides an explanation for why the gap cannot be closed empirically, as the physicalist promises. On the other hand, in his criticism of Descartes’ dualism in the Paralogismschapter, Kant argues that an ontological conclusion on the basis of this epistemological gap is unjustified even though physicalism is explanatory inadequate to account for consciousness. Thus, this epistemological dualism can be seen as an original third way between physicalist reductionism and ontological dualism. (shrink)

On at least one of its uses, ‘higher-order evidence’ refers to evidence about what opinions are rationalized by your evidence. This chapter surveys the foundational epistemological questions raised by such evidence, the methods that have proven useful for answering them, and the potential consequences and applications of such answers.

The three young philosophers Kevin Mulligan, Peter Simons and Barry Smith have become well-known in the last few years especially in German-speaking analytical philosophy and phenomenology circles. This is on the one hand as a result of their historical and systematic philosophical work; but it is also because of the provocative way in which they represent their philosophy. Because they often appear in threes, they have become known as the "gang of three" or "three musketeers" or even – and (...) this in an admiring sense – "mafiosi" (Rescher). They are known primarily for the small workshops they have been organizing in uncomplicated Anglo-Saxon manner all over Europe. Their goal has been to show that analytic philosophy as it has been pursued up to now is in need of reform and also that the history of scientific philosophizing is not identical to the history of Anglo-Saxon analytic philosophy. Above all, they have tried to make more well known the Austrian tradition of scientific philosophy, and they can be given credit for having done much to promote the current interest in this tradition, which means: the history of Austrian philosophy of the 19th and early 20th centuries and its historical context in the Austro-Hungarian Empire.

This paper builds off the Our Data Ourselves research project, which examined ways of understanding and reclaiming the data that young people produce on smartphone devices. Here we explore the growing usage and centrality of mobiles in the lives of young people, questioning what data-making possibilities exist if users can either uncover and/or capture what data controllers such as Facebook monetize and share about themselves with third-parties. We outline the MobileMiner, an app we created to consider how gaining access to (...) one’s own data not only augments the agency of the individual but of the collective user. Finally, we discuss the data making that transpired during our hackathon. Such interventions in the enclosed processes of datafication are meant as a preliminary investigation into the possibilities that arise when young people are given back the data which they are normally structurally precluded from accessing.

Leibniz thinks that every created substance is causally active, and yet causally independent of every other: none can cause changes in any but itself. This is not controversial. But Leibniz also thinks that every created substance is existentially independent of every other: it is metaphysically possible for any to exist with or without any other. This is controversial. I argue that, given a mainstream reading of Leibniz’s essentialism, if one accepts the former, uncontroversial interpretation concerning causal independence, then one ought (...) also to accept the latter, controversial one concerning existential independence. This is a new way to defend the ‘existential independence’ interpretation. Moreover, this defense provides a new approach for defending the broadly ‘non-logical’ interpretive camp in the longstanding debate over Leibniz’s views on incompossibility, against perhaps the strongest objection leveled by advocates of the opposing broadly ‘logical’ interpretation.

This article re-examines Ned Block‘s ( 1997 , 2007 ) conceptual distinction between phenomenal consciousness and access consciousness. His argument that we can have phenomenally conscious representations without being able to cognitively access them is criticized as not being supported by evidence. Instead, an alternative interpretation of the relevant empirical data is offered which leaves the link between phenomenology and accessibility intact. Moreover, it is shown that Block’s claim that phenomenology and accessibility have different neural substrates is highly problematic in (...) light of empirical evidence. Finally, his claim that there can be phenomenology without cognitive accessibility is at odds with his endorsement of the 'same-order-theory' of consciousness. (shrink)

Leibniz accepts causal independence, the claim that no created substance can causally interact with any other. And Leibniz needs causal independence to be true, since his well-known pre-established harmony is premised upon it. So, what is Leibniz’s argument for causal independence? Sometimes he claims that causal interaction between substances is superfluous. Sometimes he claims that it would require the transfer of accidents, and that this is impossible. But when Leibniz finds himself under sustained pressure to defend causal independence, those are (...) not the reasons that he marshals in its defense. Instead, deep into his long correspondence with Burchard de Volder, he gives a different sort of argument, one that has gone nearly unnoticed by commentators and has not yet been properly understood. In part, this is because the argument develops slowly over four years of correspondence. It emerges in early 1704, but it is formulated tersely and appears murky unless understood in light of Leibniz and De Volder’s tangled exchanges. There Leibniz argues that, on his distinctive ontology of an infinity of created substances, no two created substances could possibly causally interact, for roughly the same reasons that some Cartesians like De Volder deny interaction between minds and bodies on their substance dualist ontology. In this paper I draw out this lost argument, explain it and the metaphysics on which Leibniz builds it, and untangle Leibniz and De Volder’s exchanges concerning causation from which this argument results.

Willful ignorance is an important concept in criminal law and jurisprudence, though it has not received much discussion in philosophy. When it is mentioned, however, it is regularly assumed to be a kind of self-deception. In this article I will argue that self-deception and willful ignorance are distinct psychological kinds. First, some examples of willful ignorance are presented and discussed, and an analysis of the phenomenon is developed. Then it is shown that current theories of self-deception give no support to (...) the idea that willful ignorance is a kind of self-deception. Afterwards an independent argument is adduced for excluding willful ignorance from this category. The crucial differences between the two phenomena are explored, as are the reasons why they are so easily conflated. (shrink)

There are many things—call them ‘experts’—that you should defer to in forming your opinions. The trouble is, many experts are modest: they’re less than certain that they are worthy of deference. When this happens, the standard theories of deference break down: the most popular (“Reflection”-style) principles collapse to inconsistency, while their most popular (“New-Reflection”-style) variants allow you to defer to someone while regarding them as an anti-expert. We propose a middle way: deferring to someone involves preferring to make any decision (...) using their opinions instead of your own. In a slogan, deferring opinions is deferring decisions. Generalizing the proposal of Dorst (2020a), we first formulate a new principle that shows exactly how your opinions must relate to an expert’s for this to be so. We then build off the results of Levinstein (2019) and Campbell-Moore (2020) to show that this principle is also equivalent to the constraint that you must always expect the expert’s estimates to be more accurate than your own. Finally, we characterize the conditions an expert’s opinions must meet to be worthy of deference in this sense, showing how they sit naturally between the too-strong constraints of Reflection and the too-weak constraints of New Reflection.
