In this chapter we consider unsupervised learning from two perspectives. First, we briefly look at its advantages and disadvantages as an engineering technique applied to large corpora in natural language processing. While supervised learning generally achieves greater accuracy with less data, unsupervised learning offers significant savings in the intensive labour required for annotating text. Second, we discuss the possible relevance of unsupervised learning to debates on the cognitive basis of human language acquisition. In this context we explore the implications of (...) recent work on grammar induction for poverty of stimulus arguments that purport to motivate a strong bias model of language learning, commonly formulated as a theory of Universal Grammar (UG). We examine the second issue both as a problem in computational learning theory, and with reference to empirical work on unsupervised Machine Learning (ML) of syntactic structure. We compare two models of learning theory and the place of unsupervised learning within each of them. Looking at recent work on part of speech tagging and the recognition of syntactic structure, we see how far unsupervised ML methods have come in acquiring different kinds of grammatical knowledge from raw text.

Guilt and shame are self-conscious emotions with implications for mental health, social and occupational functioning, and the effectiveness of sports practice. To date, the assessment and role of athlete-specific guilt and shame has been under-researched. Reporting data from 174 junior elite cricketers, the present study utilized exploratory factor analysis in validating the Athletic Perceptions of Performance Scale, assessing three distinct and statistically reliable factors: athletic shame-proneness, guilt-proneness, and no-concern. Conditional process analysis indicated that APPS shame-proneness mediated the relationship between general (...) and athlete-specific distress. While APPS domains of guilt-proneness and no-concern were not significant mediators, they exhibited correlations in the expected direction with indices of psychological distress and well-being. The APPS may assist coaches and support staff identify players who may benefit from targeted interventions to reduce the likelihood of experiencing shame-prone states. (shrink)

Semanticists face substitution challenges even outside of contexts commonly recognized as opaque. Jennifer M. Saul has drawn attention to pairs of simple sentences - her term for sentences lacking a that-clause operator - of which the following are typical: -/- (1) Clark Kent went into the phone booth, and Superman came out. (1*) Clark Kent went into the phone booth, and Clark Kent came out. -/- (2) Superman is more successful with women than Clark Kent. (2*) Superman is more successful (...) with women than Superman. -/- She challenges us to explain why the upper and lower sentences in each pair differ, or at least appear to differ, in their truth-values and hence truth-conditions. This appearance of substitution failure is inherently puzzling. Moreover, it is taken by Saul to generate a dilemma for anyone hostile to direct reference accounts of that-clause constructions. Direct reference theorists regard the appearance of substitution failure in that-clause contexts as mere appearance, to be dealt with pragmatically rather than semantically. -/- Critics of such accounts need to say something about simple-sentence cases. If they choose to allow that intuitions of substitution failure can be over-ridden and explained away pragmatically in simple-sentence cases but not in that-clause cases, they lay themselves open to the charge of operating a double standard. But if they do not choose this option, they must offer a semantic explanation of apparent substitution failure in simple-sentence cases - no easy task, it turns out. Other respondents to Saul's challenge have sought to provide elaborate semantic treatments. In contrast, this paper proposes a far simpler pragmatic explanation of intuitions of substitution failure in simple sentences, an explanation that deploys no more resources than are to be found in Grice's 'Logic and Conversation'. Ironically, this proposal turns out to be incompatible with a direct reference perspective. So if it is, as I maintain, the most plausible treatment of simple-sentence cases available, Saul's initial thought gets turned around 180 degrees: the phenomenon she has drawn attention to ends up representing a challenge to supporters of direct reference theories.

The Italian-born Lanfranc of Pavia and his more illustrious pupil and compatriot Anselm of Bec have long been considered pivotal figures in the theological and especially philosophical developments of the late eleventh century. Long ago dubbed the “father of Scholasticism” on account of his attempts to harmonize reason and faith, Anselm has occasioned increasing scrutiny in recent years as scholars have begun to target the cultural and pedagogical role of Anselm and his milieu in the early stages of the twelfth-century (...) renaissance. In a particularly stimulating interdisciplinary exploration of the cognitive relation between builders and their craft and masters and theirs, Charles M. Radding and William W. Clark have advanced an intriguing model suggesting that theologians and Romanesque builders of the eleventh and twelfth centuries were part of a larger transformative development in which thinkers and artisans developed new methods for solving new problems; these new methods, in turn, transformed practitioners of a craft into members of new and distinct disciplines. The verdict is still out on the precise nature of those important developments, but especially vexing is the question of the abbey of Bec's importance and influence under Lanfranc and Anselm during these changing times. As a leading scholar of Anselm has recently put it, “The character of the school of Bec emerges as a riddle to be solved. What was its focus, what did its teachers teach, and how long did it last?” Recent studies have modified Richard Southern's portrayal of the curriculum of Anselm's school at Bec as largely devoted to monastic ideals and demonstrated that history and law were also studied, that a good number of students went on to become able administrators, and that Anselm may have unwittingly contributed to the rise of courtly love. Much of the fog surrounding the authorial publication and dissemination of Anselm's writings has recently been cleared by Richard Sharpe's meticulous analysis in “Anselm as Author,” revealing a careful and more deliberate editorial planning on Anselm's part than previously recognized. However, even amidst the gathering attention directed toward these figures and their cultural context, it is the most basic and obvious feature of Lanfranc's and Anselm's written record that has been the most undeservedly neglected: their use of dialogue and its correlation to the early development of Scholastic disputation. To be sure, the revival of dialectic in the eleventh century and especially in the twelfth has long been known and rather well charted, particularly with regard to the growth of theology as an academic discipline. What follows is a somewhat more focused line of inquiry. Looking beyond the well-trodden ground of Anselm's philosophy and theology and instead examining his pedagogical innovations, this essay explores Anselm's contribution to the development of literary dialogue and to the origins of the Scholastic disputatio, both valuable tools indeed in his philosophical and theological endeavors. Anselm's influence as a prolific author of dialogues can especially be observed in a younger generation of writers and thinkers who studied with him or directly sought to imitate his style and whose oeuvres need also to be considered. By examining the circle of Lanfranc and Anselm, the methods embodied by their teachings, and the writings they produced, this essay aims to show that the Scholastic dialectical methods, later so prominent in medieval universities, have their origins within the general milieu of monastic learning. More specifically, these methods will be shown to have their origins in Lanfranc's and Anselm's engagement with dialogue and disputation at the school of Bec. (shrink)

The proposal by Clarke and Beck offers a new explanation for the association between the approximate number system and math. Previous explanations have largely relied on developmental arguments, an underspecified notion of the ANS as an “error detection mechanism,” or affective factors. The proposal that the ANS represents rational numbers suggests that it may directly support a broader range of math skills.

In "Mathematical Truth", Paul Benacerraf articulated an epistemological problem for mathematical realism. His formulation of the problem relied on a causal theory of knowledge which is now widely rejected. But it is generally agreed that Benacerraf was onto a genuine problem for mathematical realism nevertheless. Hartry Field describes it as the problem of explaining the reliability of our mathematical beliefs, realistically construed. In this paper, I argue that the Benacerraf Problem cannot be made out. There simply is no intelligible problem (...) that satisfies all of the constraints which have been placed on the Benacerraf Problem. The point generalizes to all arguments with the structure of the Benacerraf Problem aimed at realism about a domain meeting certain conditions. Such arguments include so-called "Evolutionary Debunking Arguments" aimed at moral realism. I conclude with some suggestions about the relationship between the Benacerraf Problem and the Gettier Problem. (shrink)

We investigate the impact of informal arguments on judgments about thought experiment cases in light of Deutsch and Cappelen’s mischaracterization view, which claims that philosophers’ case judgments are primarily based on arguments and not intuitions. If arguments had no influence on case judgments, this would seriously challenge whether they are, or should be, based on arguments at all—and not on other cognitive sources instead, such as intuition. In Experiment 1, we replicated Wysocki’s (Rev Philos Psychol 8(2):477–499, 2017) pioneering study on (...) a Gettier-style case, and we confirmed that the informal arguments used by him had no significant effect. However, we also included an improved argument for ascribing knowledge, which did have a significant effect even in Wysocki’s original design. We therefore followed up with Experiment 2 on three Gettier-style cases, where we used a more natural dialogical format for presenting both case descriptions and informal arguments. Overall, we found a clear impact of prima facie good pro and con arguments on case judgments. The issue of argument impact is thus no obstacle to arguing about thought experiments. (shrink)

There are at least two different aspects of our rational evaluation of agents’ doxastic attitudes. First, we evaluate these attitudes according to whether they are supported by one’s evidence (substantive rationality). Second, we evaluate these attitudes according to how well they cohere with one another (structural rationality). In previous work, I’ve argued that substantive and structural rationality really are distinct, sui generis, kinds of rationality – call this view ‘dualism’, as opposed to ‘monism’, about rationality – by arguing that the (...) requirements of substantive and structural rationality can come into conflict. In this paper, I push the dialectic on this issue forward in two main ways. First, I argue that the most promising ways of resisting the diagnosis of my cases as conflicts still end up undermining monism in different ways. Second, supposing for the sake of argument that we should understand the cases as conflicts, I address the question of what we should do when such conflicts arise. I argue that, at least in a prominent kind of conflict case, the coherence requirements take precedence over the evidential requirements. (shrink)

Some combinations of attitudes--of beliefs, credences, intentions, preferences, hopes, fears, and so on--do not fit together right: they are incoherent. A natural idea is that there are requirements of "structural rationality" that forbid us from being in these incoherent states. Yet a number of surprisingly difficult challenges arise for this idea. These challenges have recently led many philosophers to attempt to minimize or eliminate structural rationality, arguing that it is just a "shadow" of "substantive rationality"--that is, correctly responding to one's (...) reasons. -/- In *Fitting Things Together*, Alex Worsnip pushes back against this trend--defending the view that structural rationality is a genuine kind of rationality, distinct from and irreducible to substantive rationality, and tackling the most important challenges for this view. In so doing, he gives an original positive theory of the nature of coherence and structural rationality that explains how the diverse range of instances of incoherence can be unified under a general account, and how facts about coherence are normatively significant. He also shows how a failure to focus on coherence requirements as a distinctive phenomenon and distinguish them adequately from requirements of substantive rationality has led to confusion and mistakes in several substantive debates in epistemology and ethics. -/- Taken as a whole, Fitting Things Together provides the first sustained defense of the view that structural rationality is a genuine, autonomous, unified, and normatively significant phenomenon.

All these specialist aspects of one life are different facets of the intellectual diamond which scintillates in the huge quarry of The Bertrand Russell Archives at McMaster University, Hamilton, Ontario.

Outside the philosophy classroom, global skeptics – skeptics about all (purported) knowledge of the external world – are rare. But there are people who describe themselves as “skeptics” about various more specific domains, including self-professed “skeptics” about the reality of anthropogenic climate change. There is little to no philosophical literature that juxtaposes the climate change skeptic with the external world skeptic. While many “traditional” epistemologists assume that the external world skeptic poses a serious philosophical challenge in a way that the (...) climate change skeptic doesn’t, many “applied” or “social” epistemologists assume that there isn’t much to be learned from debates about the external world skeptic, finding her challenge to be distant from both common sense and real-world concerns. I try to show that both of these views are mistaken. The external world skeptic raises deep questions that are important for our everyday deliberation about what to believe, and there are significant structural parallels between the arguments for external world skepticism and those for at least a form of climate change skepticism that is idealized – but not too idealized! – from the views of flesh-and-blood climate change skeptics. As such, we have strong reasons to think in parallel about how to reply to both skeptics’ challenges. I thus finish by (briefly) considering how different widespread responses to the external world skeptic might or might not generalize happily to the climate change skeptic’s challenge. (shrink)

Especially but not exclusively in the United States, there is a significant gulf between expert opinion and public opinion on a range of important political, social, and scientific issues. Large numbers of lay people hold views contrary to the expert consensus on topics such as climate change, vaccines, and economics. Much political commentary assumes that ordinary people should defer to experts more than they do, and this view is certainly lent force by the literally deadly effects of many denials of (...) established science. But there are complex philosophical issues here, concerning, among other things, (i) what an expert is; (ii) what kind of deference is called for; (iii) and when deference is called for. This entry gives an overview of these three issues and recent work on them. It then examines some potential collective and pragmatic disadvantages of deference, before concluding with reflections on what we can say to those who distrust experts. (shrink)

Deceptive implicatures are a subtle communicative device for leading someone into a false belief. However, it is widely accepted that deceiving by means of deceptive implicature does not amount to lying. In this paper, we put this claim to the empirical test and present evidence that the traditional definition of lying might be too narrow to capture the folk concept of lying. Four hundred participants were presented with fourteen vignettes containing utterances that communicate conversational implicatures which the speaker believes to (...) be false. We further collected several potential proxy measures of lying, to get a better understanding of when a deceptive implicature is considered a case of lying. The results indicate that most implicatures (ten out of fourteen) were evaluated as lies and that lie ratings were closely tracked by the degree to which speakers were considered to have committed themselves to the truth of the content conveyed by their deceptive implicatures.

This essay examines a recent line of thought in aesthetics that challenges realist-leaning aesthetic theories. According to this line of thought, aesthetic diversity and disagreement are good, and our aesthetic judgments, responses, and attachments are deeply personal and even identity-constituting. These facts are further used to support anti-realist theories of aesthetic normativity. I aim to achieve two goals: (1) to disentangle arguments concerning diversity, disagreement, and personality; and (2) to offer realist-friendly replies to all three.

Many recent decisions in tort law attempt to combine two conceptually incommensurable features: a traditional 'but for' test of factual causation, and the scientific or medical evidence that is required to explain how some injury occurred. Even when applied to macroscopic objects, the 'but for' test fails to identify causes, because it merely rephrases in the language of possible worlds what may be inferred from what is inductively known about the actual world. Since scientific theories explain the occurrence of events (...) without reference to causes, this test of causation is not only ineffectual but also inapplicable to scientific or medical evidence. Tort law, therefore, should abandon the 'but for' test; when scientific or medical evidence is required in a tort case, the courts should rely on the explanatory strategies that function within the theories from which they borrow such evidence.

The typical kind of color realism is reductive: the color properties are identified with properties specified in other terms (as ways of altering light, for instance). If no reductive analysis is available — if the colors are primitive sui generis properties — this is often taken to be a convincing argument for eliminativism. That is, realist primitivism is usually thought to be untenable. The realist preference for reductive theories of color over the last few decades is particularly striking in light (...) of the generally anti-reductionist mood of recent philosophy of mind. The parallels between the mind—body problem and the case of color are substantial enough that the difference in trajectory is surprising. While dualism and non-reductive physicalism are staples, realist primitivism is by and large a recent addition to the color literature. And it remains a minority position, although one that is perhaps gaining support. In this paper, we investigate whether it should be accepted, and conclude it should not be. (shrink)

In the Transcendental Aesthetic (TA), Kant is typically held to make negative assertations about “things in themselves,” namely that they are not spatial or temporal. These negative assertions stand behind the “neglected alternative” problem for Kant’s transcendental idealism. According to this problem, Kant may be entitled to assert that spatio-temporality is a subjective element of our cognition, but he cannot rule out that it may also be a feature of the objective world. In this paper, I show in a new (...) way how Kant’s view (focusing on his conclusions about space) is not subject to this objection, by showing that he does not make the denial about mind-independent reality that he is typically held to make. The argument develops consequences of a new reading of Kant’s expression “an sich selbst” (‘in itself’; ‘in themselves’). I argue that “an sich selbst” or “per se” has a special, judgment-level role, so that this expression does not form new noun-terms adjectivally. It follows that the conceptual unit of Kant’s “Conclusions” in the TA is simply “things” (Dinge), since “things in themselves” is not a nominal expression; Kant adopts the Wolffian ontological use of “thing” as the basic kind-term for any existent. The arguments that things per se are not in space are arguments that space cannot be a necessary property or relations of things as a kind. I show that this does not involve the positive claim about mind-independent reality that inspires the neglected alternative objection. (shrink)

John Dupr argues that 'scientific imperialism' can result in 'misguided' science being considered acceptable. 'Misguided' is an explicitly normative term and the use of the pejorative 'imperialistic' is implicitly normative. However, Dupr has not justified the normative dimension of his critique. We identify two ways in which it might be justified. It might be justified if colonisation prevents a discipline from progressing in ways that it might otherwise progress. It might also be justified if colonisation prevents the expression of important (...) values in the colonised discipline. This second concern seems most pressing in the human sciences. (shrink)

The term ‘coherence’ (and its antonym ‘incoherence’) is used in a bewildering variety of ways in epistemology (and in philosophy more broadly). This entry attempts to bring some discipline to uses of the term by offering a taxonomy of notions of coherence (and incoherence), and then surveying which of the resulting notions is (or should be) at work in the various different contexts in which it is deployed.

The lack of access to gender-affirming surgery represents a significant unmet health care need within the transgender community, frequently resulting in depression and self-destructive behavior. While some transgender people may have access to gender reassignment surgery, an overwhelming majority cannot afford facial feminization surgery. The former may be covered as a “medical necessity,” but FFS is considered “cosmetic” and excluded from insurance coverage. This demarcation between “necessity” and “cosmetic” in transgender health care based on specific body parts is in direct (...) opposition to the scientific community’s understanding of gender dysphoria and professional guidelines for transgender health. GRS affects one’s ability to function in an intimate relationship, while FFS has the same impact on social interactions an, therefore may have a far greater implication for one’s quality of life. FFS is a cost-effective intervention that needs to be covered by insurance policies. The benefits of such coverage far exceed the insignificant costs. (shrink)

In this paper, we consider how certain longstanding philosophical questions about mental representation may be answered on the assumption that cognitive and perceptual systems implement hierarchical generative models, such as those discussed within the prediction error minimization framework. We build on existing treatments of representation via structural resemblance, such as those in Gładziejewski :559–582, 2016) and Gładziejewski and Miłkowski, to argue for a representationalist interpretation of the PEM framework. We further motivate the proposed approach to content by arguing that it (...) is consistent with approaches implicit in theories of unsupervised learning in neural networks. In the course of this discussion, we argue that the structural representation proposal, properly understood, has more in common with functional-role than with causal/informational or teleosemantic theories. In the remainder of the paper, we describe the PEM framework for approximate Bayesian inference in some detail, and discuss how structural representations might arise within the proposed Bayesian hierarchies. After explicating the notion of variational inference, we define a subjectively accessible measure of misrepresentation for hierarchical Bayesian networks by appeal to the Kullbach–Leibler divergence between posterior generative and approximate recognition densities, and discuss a related measure of objective misrepresentation in terms of correspondence with the facts.

Traditionally, perceptual experiences—for example, the experience of seeing a cat—were thought to have two quite distinct components. When one sees a cat, one’s experience is “about” the cat: this is the representational or intentional component of the experience. One’s experience also has phenomenal character: this is the sensational component of the experience. Although the intentional and sensational components at least typically go together, in principle they might come apart: the intentional component could be present without the sensational component or vice (...) versa.
