This chapter presents a re-understanding of the contents of our analog magnitude representations (e.g., approximate duration, distance, number). The approximate number system (ANS) is considered, which supports numerical representations that are widely described as fuzzy, noisy, and limited in their representational power. The contention is made that these characterizations are largely based on misunderstandings—that what has been called “noise” and “fuzziness” is actually an important epistemic signal of confidence in one’s estimate of the value. Rather than the ANS having noisy (...) or fuzzy numerical content, it is suggested that the ANS has exquisitely precise numerical content that is subject to epistemic limitations. Similar considerations will arise for other analog representations. The chapter discusses how this new understanding of ANS representations recasts the learnability problem for number and the conceptual changes that children must accomplish in the number domain.

Rips et al. consider whether representations of individual objects or analog magnitudes are building blocks for the concept natural number. We argue for a third core capacity – the ability to bind representations of individuals into sets. However, even with this addition to the list of starting materials, we agree that a significant acquisition story is needed to capture natural number.

A sentence like every circle is blue might be understood in terms of individuals and their properties or in terms of a relation between groups. Relatedly, theorists can specify the contents of universally quantified sentences in first-order or second-order terms. We offer new evidence that this logical first-order vs. second-order distinction corresponds to a psychologically robust individual vs. group distinction that has behavioral repercussions. Participants were shown displays of dots and asked to evaluate sentences with each, every, or all combined (...) with a predicate. We find that participants are better at estimating how many things the predicate applied to after evaluating sentences in which universal quantification is indicated with every or all, as opposed to each. We argue that every and all are understood in second-order terms that encourage group representation, while each is understood in first-order terms that encourage individual representation. Since the sentences that participants evaluate are truth-conditionally equivalent, our results also bear on questions concerning how meanings are related to truth-conditions. (shrink)

A multimodal person representation contains information about what a person looks like and what a person sounds like. However, little is known about how children form these face-voice mappings. Here, we explored the possibility that two cognitive tools that guide word learning, a one-to-one mapping bias and fast mapping, also guide children’s learning about faces and voices. We taught 4- and 5-year-olds mappings between three individual faces and voices, then presented them with new faces and voices. In Experiment 1, we (...) found that children rapidly learned face-voice mappings from just a few exposures, and furthermore spontaneously mapped novel faces to novel voices using a one-to-one mapping bias (that each face can produce only one voice). In Experiment 2, we found that children’s face-voice representations are abstract, generalizing to novel tokens of a person. In Experiment 3, we found that children retained in memory the face-voice mappings that they had generated via inference (i.e., they showed evidence of fast mapping), and used these newly formed representations to generate further mappings between new faces and voices. These findings suggest that preschoolers’ rapid learning about faces and voices may be aided by biases that are similar to those that support word learning. (shrink)

The meaning of 'most' can be described in many ways. We offer a framework for distinguishing semantic descriptions, interpreted as psychological hypotheses that go beyond claims about sentential truth conditions, and an experiment that tells against an attractive idea: 'most' is understood in terms of one-to-one correspondence. Adults evaluated 'Most of the dots are yellow', as true or false, on many trials in which yellow dots and blue dots were displayed for 200 ms. Displays manipulated the ease of using a (...) 'one-to-one with remainder' strategy, and a strategy of using the Approximate Number System to compare of (approximations of) cardinalities. Interpreting such data requires care in thinking about how meaning is related to verification. But the results suggest that 'most' is understood in terms of cardinality comparison, even when counting is impossible. (shrink)

This paper proposes an Interface Transparency Thesis concerning how linguistic meanings are related to the cognitive systems that are used to evaluate sentences for truth/falsity: a declarative sentence S is semantically associated with a canonical procedure for determining whether S is true; while this procedure need not be used as a verification strategy, competent speakers are biased towards strategies that directly reflect canonical specifications of truth conditions. Evidence in favor of this hypothesis comes from a psycholinguistic experiment examining adult judgments (...) concerning ‘Most of the dots are blue’. This sentence is true if and only if the number of blue dots exceeds the number of nonblue dots. But this leaves unsettled, e.g., how the second cardinality is specified for purposes of understanding and/or verification: via the nonblue things, given a restriction to the dots, as in ‘|{x: Dot(x) & ~Blue(x)}|’; via the blue things, given the same restriction, and subtraction from the number of dots, as in ‘|{x: Dot(x)}| – |{x: Dot(x) & Blue(x)}|’; or in some other way. Psycholinguistic evidence and psychophysical modeling support the second hypothesis. (shrink)

Given a rich environment, how do we decide on what information to use? A view of a single entity (e.g., a group of birds) affords many distinct interpretations, including their number, average size, and spatial extent. An enduring challenge for cognition, therefore, is to focus resources on the most relevant evidence for any particular decision. In the present study, subjects completed three tasks—number discrimination, surface area discrimination, and convex hull discrimination—with the same stimulus set, where these three features were orthogonalized. (...) Therefore, only the relevant feature provided consistent evidence for decisions in each task. This allowed us to determine how well humans discriminate each feature dimension and what evidence they relied on to do so. We introduce a novel computational approach that fits both feature precision and feature use. We found that the most relevant feature for each decision is extracted and relied on, with minor contributions from competing features. These results suggest that multiple feature dimensions are separately represented for each attended ensemble of many items and that cognition is efficient at selecting the appropriate evidence for a decision.

Quantificational determiners are often said to be devices for expressing relations. For example, the meaning of _every_ is standardly described as the inclusion relation, with a sentence like _every frog is green_ meaning roughly that the green things include the frogs. Here, we consider an older, non-relational alternative: determiners are tools for creating restricted quantifiers. On this view, determiners specify how many elements of a restricted domain (e.g., the frogs) satisfy a given condition (e.g., being green). One important difference concerns (...) how the determiner treats its two grammatical arguments. On the relational view, the arguments are on a logical par as independent terms that specify the two relata. But on the restricted view, the arguments play distinct logical roles: specifying the limited domain versus supplying an additional condition on domain entities. We present psycholinguistic evidence suggesting that the restricted view better describes what speakers know when they know the meaning of a determiner. In particular, we find that when asked to evaluate sentences of the form _every F is G_, participants mentally group the Fs but not the Gs. Moreover, participants forego representing the group defined by the intersection of F and G. This tells against the idea that speakers understand _every F is G_ as implying that the Fs bear relation (e.g., inclusion) to a second group. (shrink)

Since the time of Hippocrates, madness has typically been viewed through the lens of disease, dysfunction, and defect. In 'Madness', philosopher of science Justin Garson presents a radically different paradigm for conceiving of madness and the forms that it takes. In this paradigm, which he calls madness-as-strategy, madness is neither a disease nor a defect, but a designed feature, like the heart or lungs.

This paper argues for contrastivism about the deontic modals, 'ought', 'must', and 'may'. A simple contrastivist semantics that predicts the desired entailment relations among these modals is offered.

The Oxford Handbook of Chinese Philosophy is a collection of essays on important texts and figures in the history of Chinese thought. The essays cover both well-known texts such as the Analects and the Zhuangzi as well as many of the lesser-known thinkers in the classical and post-classical Chinese tradition. Most of the chapters focus on thinkers or texts in one of three important historical movements: Classical ("pre-Qin") Chinese philosophy, Chinese Buddhism, and the Confucian response to Buddhism ("neo-Confucianism" broadly construed).

This is a short overview of the biological functions debate in philosophy. While it was fairly comprehensive when it was written, my short book ​A Critical Overview of Biological Functions has largely supplanted it as a definitive and up-to-date overview of the debate, both because the book takes into account new developments since then, and because the length of the book allowed me to go into substantially more detail about existing views.

The downsides of monogamy are felt by most people engaged in long-term relationships, including restrictions on self-discovery, limits on friendship, sexual boredom, and a circumscribed understanding of intimacy. Yet, a "happily ever after" monogamy is assumed to be the ideal form of romantic love in many modern societies: a relationship that is morally ideal and will bring the most happiness to its two partners. -/- In Why It’s OK to Not Be Monogamous, Justin L. Clardy deeply questions these assumptions. (...) He rejects the claim that non-monogamy among honest, informed and consenting adults is morally impermissible. He shows instead how polyamorous relationships can actually be exemplars of moral virtue. The book discusses how social and political forces sustain and reward monogamous relationships. The book defines non-monogamy as a privative concept; a negation of monogamy. Looking at its prevalence in the United States, the book explains how common criticisms of non-monogamy come up short. Clardy argues, as some researchers have recently shown―monogamy relies on continually demonizing non-monogamy to sustain its moral status. Finally, the book concludes with a focus on equality, asking what justice for polyamorous individuals might look like. (shrink)

Most a posteriori arguments against the existence of God take the following form: (1) If God exists, the world would not be like this (where 'this' picks out some feature of the world like the existence of evil, etc.) (2) But the world is like this . (3) Therefore, God does not exist. Skeptical theists are theists who are skeptical of our ability to make judgments of the sort expressed by premise (1). According to skeptical theism, if there were a (...) God, it is likely that he would have reasons for acting that are beyond our ken, and thus we are not justified in making all-things-considered judgments about what the world would be like if there were a God. In particular, the fact that we don't see a good reason for X does not justify the conclusion that there is no good reason for X. 1 Thus, skeptical theism purports to undercut most a posteriori arguments against the existence of God. What follows is an account of the nature of skeptical theism, an application of skeptical theism to both the argument from evil and the argument from divine hiddenness, and a review of the cases for and against skeptical theism.

Leading researchers in the philosophy of mind present and explore cutting edge research in the exciting new field of experimental philosophy.

Both advocates and critics of experimental philosophy often describe it in narrow terms as being the empirical study of people’s intuitions about philosophical cases. This conception corresponds with a narrow origin story for the field—it grew out of a dissatisfaction with the uncritical use of philosophers’ own intuitions as evidence for philosophical claims. In contrast, a growing number of experimental philosophers have explicitly embraced a broad conception of the sub-discipline, which treats it as simply the use of empirical methods to (...) inform philosophical problems. And this conception has a corresponding broad origin story—the field grew out of a recognition that philosophers often make empirical claims and that empirical claims call for empirical support. In this paper, I argue that the broad conception should be accepted, offering support for the broad origin story. (shrink)

Because anticipated and retrospective regret play important roles in practical deliberation and motivation, better understanding them can illuminate the contours of human agency. However, the possibility of self-ignorance and the fact that we change over time can make regret—especially anticipatory regret—not only a poor predictor of where the agent will be in the future but also an unreliable indicator of where the agent stands. Granting these, this paper examines the way in which prospective and, particularly, retrospective regret can nevertheless yield (...) important insight into the sorts of creatures we are, both generally and individually. The experience of retrospective regret can show a person she values something in a way she did not know or that she is (or was) a different person than she had thought, insights which can factor into forward-looking, or prospective, deliberation. Such instances of revelatory regret reveal something to the agent about herself as agent. I examine two cases of agential self-ignorance. In the first, the experience of regret reveals what the agent values, not only to others but even to the agent himself. In the second, the agent anticipates experiencing regret for an action but does not experience the regret, suggesting that the agent did not value the rejected alternative in the way she thought. Anticipatory regret is forward-looking and can play an important role in practical deliberation. But insofar as anticipatory regret flows from one’s imperfect judgment and prospection about oneself, retrospective regret can be an important corrective in helping the agent understand her own standpoint.

Using the latest cognitive and psychological scientific data and theory, this book answers the question "why would anyone believe in God?".

A crucial tenet of virtue-based or expertise-based theorizing about politics is that there are ways to identify and select morally and epistemically excellent people to hold office. This paper considers historical challenges to this task that come from within Greek and Confucian thought and political practice. Because of how difficult it is to assess character in ordinary settings, we argue that it is even more difficult to design institutions that select for virtue at the much wider political scale. Specifically, we (...) argue that the vast majority of proposals that purport to select for virtue are either (a) unlikely to be effective, (b) not implementable at the scale of most current nations, or (c) have already been incorporated into most democratic states. Thus defenders of meritocratic institutions should take more seriously the practical barriers that will almost certainly arise when trying to implement these proposals at scale. Historical proponents of meritocratic values were well aware of concerns about the feasibility of their political ideals, and we should be too. (shrink)

This chapter focuses on attributions of phenomenal consciousness, leaving to the side interesting questions about how people attribute other types of consciousness. While researchers are not in perfect agreement about how the concept of phenomenal consciousness should be understood, the standard line is that a creature is phenomenally conscious just in case it has phenomenally conscious mental states, and that a mental state is phenomenally conscious just in case it has phenomenal qualities. The chapter explores whether lay people employ the (...) concept of phenomenal consciousness. It begins by looking at the evidence for an affirmative answer to this question, focusing on Joshua Knobe and Jesse Prinz's article, Intuitions About Consciousness: Experimental Studies. The chapter explains the evidence for a negative answer to the target question, focusing on Justin Sytsma and Edouard machery's article, Two Conceptions of Subjective Experience. (shrink)

Contrastivism about ‘ought’ holds that ‘ought’ claims are relativized, at least implicitly, to sets of mutually exclusive but not necessarily jointly exhaustive alternatives. This kind of theory can solve puzzles that face other linguistic theories of ‘ought’, via the rejection or severe restriction of principles that let us make inferences between ‘ought’ claims. By rejecting or restricting these principles, however, the contrastivist takes on a burden of recapturing acceptable inferences that these principles let us make. This paper investigates the extent (...) to which a contrastivist can do this. (shrink)

In this chapter, I consider two hypotheses that have informed recent work in experimental philosophy of mind. The first is a positive hypothesis put forward by Fiala, Arico, and Nichols : Categorization of an entity as an agent through fast, automatic, and domain-specific processing produces a disposition to ascribe a wide range of mental states to that entity. The second is a negative hypothesis put forward by Sytsma and Machery: The existence of phenomenally conscious mental states is not obvious from (...) first-person experience with states like seeing red and feeling pain. I argue that these hypotheses are not necessary at odds. Despite this, empirical results reported by Sytsma and Machery raise concerns for FAN's hypothesis, while results reported by FAN in response raise concerns for our hypothesis. I address these concerns in this essay, presenting the results of four new studies that support our negative hypothesis against FAN's challenge. (shrink)

Contemporary metaphysics is dominated by the view that every object belongs to a kind permanently in the sense that it cannot cease to belong to that kind without thereby ceasing to exist. For example, some philosophers think that a person is destroyed if they cease to be a person, a statue is destroyed if it ceases to be a statue, and so on. I believe that this standard view is false. Being a person, or a statue, or etc., is like (...) being a child: just as I did not cease to exist when I ceased to be a child, so people and statues need not cease to exist when they cease to be people and statues. Borrowing a term from Daniel Korman (who uses it in a similar but perhaps not identical way), I call this view phasalism because it entails that the kind-properties which ordinary objects instantiate are phase sortal properties, i.e., kind-properties that an object can instantiate for a temporary phase of its career. This dissertation is a partial defense of phasalism. I develop a phasalist metaphysics in detail, highlighting its virtues and rebutting objections along the way. After some stage-setting (Chapter 1), I defend a phasalist criterion of identity over time for ordinary objects (Chapter 2), as well as a phasalist account of the role that sortal properties play in the identity over time of ordinary objects (Chapter 3). Then I defend a phasalist-friendly approach to the identity over time of lumps, hunks, pieces, etc. of matter (Chapter 4). The material in these chapters amounts to a phasalist solution to certain material coincidence puzzles, such as the puzzle of the statue and the piece of clay. I go on to show that familiar puzzles about undetached parts (Chapter 5) and fission (Chapter 6) can be solved within the confines of my phasalist metaphysics as well. (shrink)

Beliefs have genealogies. Can tracing a belief’s genealogy illuminate the epistemic quality of the belief? This paper sets out a general epistemology of genealogies. As it turns out, genealogies for beliefs come in two sorts: those that trace a belief to some mental event that doubles as evidence for the belief and those that do not. The former have the potential to undercut the belief, rebut the belief, or—importantly—both. The latter have the potential to reinforce the belief or rebut the (...) belief but—importantly—not undercut it. The ultimate conclusion is that there is a role for genealogies in the epistemic appraisal of our beliefs, but this role will be circumscribed by the availability of clear and compelling genealogies.

In this paper I argue that when thinking about justice, political philosophers should pay more attention to social norms, not just the usual subjects of basic principles, rights, laws, and policies. I identify two widely-endorsed ideas about political philosophy that interfere with recognizing the importance of social norms—ideas I dub ‘compulsoriness’ and ‘institutionalism’—and argue for their rejection. I do this largely by focusing on questions about who can and should be an agent of justice. I argue that careful reflection on (...) these questions supports a kind of pluralism that reveals the importance of social norms, three types of which I discuss. (shrink)

This work analyses Marx's philosophy of nature and shows how it is the basis for his practical philosophy. Previous analysis of Marx's philosophy of nature has considered humans as only natural beings and social beings. But, Marx analyzed humans' relationship to the natural world and to themselves as natural, social, and material. This material feature of human action can server as a basis for social critique and as the foundation for a practical analysis. The first chapter of this book analyzes (...) Marx's philosophy of nature from his early to late works and argues that humans are natural begins that use nature to develop new capacities. This consideration is central in Marx's critiques of Hegel and Feuerbach. The second chapter discusses Marx's material critique of social forms and discusses why the distinction between material action and social action is a key component of Marx critique of capitalism. This chapter also discusses industrial history, ideology, wages, justice, and valorization. The third and final chapter builds on Marx's materialist analysis to develop a standard of practical action that takes human's material activity as its basis. This chapter also discusses classical historical materialist claims, liberal ethical theories, and a practical philosophic consideration of socialism. (shrink)

Moral luck is a puzzling aspect of our psychology: Why do we punish outcomes that were not intended (i.e. accidents)? Prevailing psychological accounts of moral luck characterize it as an accident or error, stemming either from a re‐evaluation of the agent's mental state or from negative affect aroused by the bad outcome itself. While these models have strong evidence in their favor, neither can account for the unique influence of accidental outcomes on punishment judgments, compared with other categories of moral (...) judgment. Why might punishment be particularly sensitive to moral luck? We suggest that such sensitivity is easily understood from the broader perspective of punishment's ultimate adaptive goal: Changing others’ behavior by exploiting their capacity to learn. This pedagogical perspective accounts for the exceptional influence of outcomes on punitive sentiments and makes predictions for additional moderators of punishment. We review evidence supporting the pedagogical hypothesis of punishment and discuss fruitful directions for future research. (shrink)

Tourism literature has shown there is a disagreement amongst academics conducting tourism research as to whether tourism is an academic community, academic study, and/or academic discipline. These three terms are used loosely and change in meaning depending upon the author, source, context, and discipline of the author(s). The following paper identifies tourism’s current position in academia using these three ideas of academic acceptance as tools to guide the discussion. Also guiding the discussion are ideas from tourism scholars and Kuhn’s ideas (...) of what constitutes a discipline. The discussion leads to a debate about “truths” in tourism research. Recommendations regarding the advancement of tourism in academia via theory construction in the academic field of tourism are presented. (shrink)

This book addresses a longstanding controversy concerning whether Frankfurt cases—thought experiments of a sort devised by Harry Frankfurt—are counterexamples to the principle of alternative possibilities (roughly, the principle that a person is morally responsible for what he did only if he could have avoided doing it). Frankfurt and many others contend that they are, but here it is argued that, far from being counterexamples to the principle, Frankfurt cases actually provide further confirmation of it, a conclusion that has important implications (...) for our understanding of free will and moral responsibility.

This chapter examines the convention concerning the theories of generation and form in the field of natural philosophy in Great Britain during the seventeenth century. It explains that natural philosophers treated the questions of biological generation interchangeably with those coming from chemistry, mineralogy, and meteorology, and considers Antoine Goudin's argument that there are both efficient and final causes at work in the earth's production of rocks that resemble animals or parts of animals. The chapter also suggests that the ‘chymists’ were (...) consistently presented as a challenging third party, alongside Aristotelianism and traditional atomism, in the effort to account for the composition of natural bodies.

In The Sickness unto Death, Kierkegaard describes selfhood as an achievement, specifically claiming that the self’s task ‘is to become itself’ (SUD, 29/SKS 11, 143). But how can one can become who or what one already is, and what sort of achievement is it? This chapter draws on the work of Christine Korsgaard, another philosopher who sees selfhood as an achievement, using her notion of practical identity to explore Kierkegaard’s accounts of the structure of the self and of selfhood as (...) achievement. Kierkegaard’s treatment of selfhood—as aspirational and, if undertaken well, appropriately grounded in one’s facticity (i.e. the concrete facts of one’s situation)—suggests how consciously endorsed identities can guide (or fail to guide) our agency. Having a practical identity involves striving to inhabit adopted roles by aligning our actions with relevant normative demands, but also sometimes embracing and consciously adopting identities already tacitly guiding our engagement with the world. This framework also suggests several ways we can be alienated from desires, actions, or, more generally, our selves. Putting Kierkegaard in conversation with contemporary agency theory, this chapter has two guiding lines of inquiry. First, what does it mean to achieve selfhood and how can the notion of practical identity illuminate or be illuminated by this question? Second, how can this analysis clarify the experience of not being oneself, whether resulting from self-deception, self-ignorance, or the potentially frustrating gap between who one is and who one wants to be?
