Science relies on models and idealizations that are known not to be true. Even so, science is epistemically reputable. To accommodate science, epistemology should focus on understanding rather than knowledge and should recognize that the understanding of a topic need not be factive. This requires reconfiguring the norms of epistemic acceptability. If epistemology has the resources to accommodate science, it will also have the resources to show that art too advances understanding.

Tetris provides a difficult, dynamic task environment within which some people are novices and others, after years of work and practice, become extreme experts. Here we study two core skills; namely, choosing the goal or objective function that will maximize performance and a feature-based analysis of the current game board to determine where to place the currently falling zoid so as to maximize the goal. In Study 1, we build cross-entropy reinforcement learning models to determine whether different goals result in (...) different feature weights. Two of these optimization strategies quickly rise to performance plateaus, whereas two others continue toward higher but more jagged heights. In Study 2, we compare the zoid placement decisions made by our best CERL models with those made by 67 human players. Across 370,131 human game episodes, two CERL models picked the same zoid placements as our lowest scoring human for 43% of the placements and as our three best scoring experts for 65% of the placements. Our findings suggest that people focus on maximizing points, not number of lines cleared or number of levels reached. They also show that goal choice influences the choice of zoid placements for CERLs and suggest that the same is true of humans. Tetris has a repetitive task structure that makes Tetris more tractable and more like a traditional experimental psychology paradigm than many more complex games or tasks. Hence, although complex, Tetris is not overwhelmingly complex and presents a right-sized challenge to cognitive theories, especially those of integrated cognitive systems. (shrink)

What did nineteenth-century chemists know? This essay uses Emil Fischer’s classic study of the sugars in 1880s and 90s Germany to argue that chemists’ knowledge was not primarily vested in the theories of valence, structure, and stereochemistry that have been the subject of so much historical and philosophical analysis of chemistry in this period. Nor can chemistry be reduced to a merely manipulative exercise requiring little or no intellectual input. Examining what chemists themselves termed the “art of chemical experimentation” reveals (...) chemical practice as inseparable from its cognitive component, and it explains how chemists integrated theory with experiment through reason.

Jealousy has been disparaged as psychologically debilitating and morally flawed since well before Shakespeare wrote Othello and is indeed represented—particularly well—as far back as in Homer's portrayal of gods and goddesses in The Iliad. According to some of these traditional views, often shared by philosophers, psychologists and the general public, jealousy is the sign, if not of an irredeemably corrupt mind, then at least of an excessively possessive and insecure character. But does jealousy always indicate some sort of flaw or (...) failure? Is jealousy rerehensible in all contexts? In the present paper, I intend to suggest some modifications to the view that it is, by giving jealousy a more sympathetic and charitable hearing than it normally receives, and suggesting that jealousy might, in some cases, be justifiable.

In this paper, I argue for an account of metaphorical content as what is said when a speaker utters a metaphor. First, I show that two other possibilities—the Gricean account of metaphor as implicature and the strictly semantic account developed by Josef Stern—face several serious problems. In their place, I propose an account that takes metaphorical content to cross-cut the semantic-pragmatic distinction. This requires re-thinking the notion of metaphorical content, as well as the relation between the metaphorical and the literal.

This study contributes to the definition of populism as a significant current of thought in modern China through a focus on the development of the populist ideas of Liang Shuming . It provides an avenue to understanding a major thinker and social activist of modern China. At the same time, through a comparison with Russian Narodism, it develops populism as a general sociohistorical concept, denoting a constellation of ideas which emerges in a specific historical environment and includes a concern with (...) rural society and a critique of the modern West in the context of questions of the moral nature of progress. ;The dissertation describes the origins and development of Liang's ideas, presenting them against the background of major intellectual tendencies of the times. After an early urban, Westernizing focus, Liang arrived at a populist approach relatively late. A persisting habit of thought, involving a metaphor of mind, informed his early concerns, his attention to the ambiguities of progress and to the appeals of socialism, and his later foci on a critique of the West, an historical approach, and a particular concept of the psyche. The events of the 1920's provided the context in which Liang was able to reconcile his disparate concerns and develop a mature populist theory in which the villages provided a practical intersection of individual subjectivity and history. ;In the evolution of his ideas, Liang Shuming shared with other Chinese, Zhang Taiyan, Zhang Shizhao, Li Dazhao, and Mao Zedong, affinities which help define populism as a broad current of thought still important in China. A critique of the West and desire to skip over capitalism on the way to the future have more weight in Chinese populism than does a focus on rural society. In the absence of a specifically populist political movement, the historical importance of Chinese populism has derived from its interpenetration with Marxist ideas. One potential of the legacy of Chinese populism is to provide a self-conscious orientation toward the future from the perspective of a critique of both the Western present and the Chinese past.

We often form intentions to resist anticipated future temptations. But when confronted with the temptations our resolutions were designed to withstand, we tend to revise our previous evaluative judgments and conclude that we should now succumb—only to then revert to our initial evaluations, once temptation has subsided. Some evaluative judgments made under the sway of temptation are mistaken. But not all of them are. When the belief that one should now succumb is a proper response to relevant considerations that have (...) newly emerged, can acting in line with one’s previous intention nonetheless be practically rational? To answer this question, I draw on recent debates on the nature of higher-order evidence and on what rationally responding to such evidence involves. I propose that agents facing temptation often have evidence of “deliberative unreliability”, which they ought to heed even when it is “misleading” (that is, even when their evaluative judgments are in fact proper responses to the relevant considerations then available). Because evidence of deliberative unreliability can “dispossess” agents of normative reasons for evaluative judgments and actions that they would otherwise have, being continent despite judging that one should now succumb can often be more rational than giving in.

Photography has become a pervasive component of contemporary communication. Recent technological advances in creating and manipulating images have provided renewed impetus to decades-long debates on use of photographs in science. With increase in the potential for inappropriate image manipulation, fears about misrepresentation have heightened concern among journal editors and scholars about the 'accuracy' of published images. We discuss how science has responded to growing concerns surrounding falsification and inaccuracy of photography. We document progress in implementing a variety of complementary approaches (...) to addressing the problem. These include digital forensics, photo member checking and the implementation of codes of ethics to enhance the veracity of published photographs in science research. We conclude by acknowledging the irreducible conflict likely to remain between use of the photograph as a creative work of art and employment of this medium as a source of information in the progress of science.

This article recounts the development of the Professional/problem-based Ethics Program, the original physicians’ professional ethics remediation course. Since 1992, more than 1,200 healthcare professionals of many disciplines have been mandated to attend ProBE by licensing boards and other oversight entities. Using a small-group, interprofessional setting, the ProBE Program assists participants to discover and articulate ethical underpinnings violated by their misconduct; appreciate professional responsibilities that are societal, regulatory, and ethical; and recommit to professional ideals. The authors describe the rationale for developing (...) ProBE, its curriculum, participant demographics, and infractions and reconsider medical professionalism in light of two decades of ProBE.

Teaching is not testimony. Although both convey information, they have different uptake requirements. Testimony aims to impart information and typically succeeds if the recipient believes that informationon account of having been told by a reliable informant. Teaching aims to equip learners to go beyond the information given—to leverage that information to broaden, deepen, and critique their current understanding of a topic. Teaching fails if the recipients believe the information only because it is what they have been told.

The article explores the problem of nursing as a practical discipline and suggests that there are several kinds of nursing science. Following the lead of Jacques Maritain and Yves R. Simon, the authoress begins with an account of the distinguishing characteristics of theoretical knowledge, to which the term “science” has historically been applied, and distinguishes it from practical knowledge or prudence. Next she reviews Maritain and Simon’s discussion of two intermediate levels of inquiry that share some characteristics of both science (...) and practical knowledge. Finally, using the writings of several nurse theorists whose seminal ideas in this area have established a basis for nurse theorist’s discussion of these issues, she distinguishes four kinds of nursing inquiry which range from the very theoretical to the very practical.

Smoking is frequently presented as being particularly problematic when the smoker is a pregnant woman because of the potential harm to the future child. This premise is used to justify targeting pregnant women with a unique approach to smoking cessation including policies such as the routine testing of all pregnant women for carbon monoxide at every antenatal appointment. This paper examines the evidence that such policies are justified by the aim of harm prevention and argues that targeting pregnant women in (...) this way is likely to do more harm than good. Routine carbon monoxide testing is particularly problematic as it sends a message to pregnant women that they cannot be trusted either to truthfully answer questions as to whether or not they smoke, or to make decisions in the best interests of themselves and their future children in the way that non-pregnant individuals are. Further, if the aim is to reduce rates of prenatal harm, the evidence suggests that adopting a supportive and empowering approach to prenatal care is the most effective way to achieve this, something that the current policies aimed at pregnant women are in conflict with.

Testimony consists in imparting information without supplying evidence or argument to back one’s claims. To what extent does testimony convey epistemic warrant? C. J. A. Coady argues, on Davidsonian grounds, that (1) most testimony is true, hence (2) most testimony supplies warrant sufficient for knowledge. I appeal to Grice’s maxims to undermine Coady’s argument and to show that the matter is more complicated and context-sensitive than is standardly recognized. Informative exchanges take place within networks of shared, tacit assumptions that affect (...) the scope and strength of our claims, and the level of warrant required for their responsible assertion. The maxims explain why different levels of warrant are transferred in different contexts. (shrink)

This chapter explores the epistemic roles played by connectionist models of cognition, and offers a formal analysis of how connectionist models explain. It looks at how other types of computational models explain. Classical artificial intelligence (AI) programs explain using abductive reasoning, or inference to the best explanation; they begin with the phenomena to be explained, and devise rules that can produce the right outcome. The chapter also looks at several examples of connectionist models of cognition, observing what sorts of constraints (...) are used in their design, and how their results are evaluated. It argues that the point of implementing networks roughly analogous to neural structures is to discover and explores the generic mechanisms at work in the brain, not to deduce the precise activities of specific structures. The chapter explores a formal analysis of the explanations offered, which interprets connectionist models and the cognitive theories they represent as sharing membership in a type of mechanism.

A vital and underappreciated dimension of social interaction is the way individuals justify their actions to others, instinctively drawing on their experience to appeal to principles they hope will command respect. Individuals, however, often misread situations, and many disagreements can be explained by people appealing, knowingly and unknowingly, to different principles. On Justification is the first English translation of Luc Boltanski and Laurent Thévenot's ambitious theoretical examination of these phenomena, a book that has already had a huge impact on French (...) sociology and is likely to have a similar influence in the English-speaking world. In this foundational work of post-Bourdieu sociology, the authors examine a wide range of situations where people justify their actions. The authors argue that justifications fall into six main logics exemplified by six authors: civic, market, industrial, domestic, inspiration, and fame. The authors show how these justifications conflict, as people compete to legitimize their views of a situation. On Justification is likely to spark important debates across the social sciences.

Philosophers are generally somewhat wary of the hints of number mysticism in the reports about the beliefs and doctrines of the so-called Pythagoreans. It's not clear how much Pythagoras himself (as opposed to his later followers) indulged in speculation about numbers, or in more serious mathematics. But the Pythagoreans whom Aristotle discusses in the Metaphysics had some elaborate stories to tell about how the universe could be explained in terms of numbers—not just its physics but perhaps morality too. Was this (...) just fanciful speculation? Is it muddled as a theory of causality, as Aristotle suggests? I shall try to rehabilitate the passion for numbers by linking it with the notions of harmony and proportion in other thinkers who have a higher credibility factor in the philosophical stakes, and by showing that the desire to reduce quality to quantity, and to discover an exact science that can explain human life and meaning, is a serious philosophical passion that doesn't easily go away. And, after all, why should it? (shrink)

Ten years after they were set up, the Italian regions have fallen into general discredit. They are discredited by the central government who regards them as a source of support for the opposing Communist Party and has sought to undermine this reform by depriving the regions of all true autonomy. The regions are discredited by the public opinion by not fulfilling the expectations placed in them. Such an assessment does not stand up to a close examination of regional practices : (...) some geographical differences rapidly become obvious, but especially evident are the political differences. In fact, the regions are the product of an apparent agreement between the political parties and have always suffered from political bargaining which explains the national scale of the issues raised at the last elections. Strengthened by the favorable results obtained in certain regions, the Communist Party was quick to turn this statement of the electoral opinion into a « referendum » about the newly formed Cossiga government.

Much can be gained by specifying the operation of the emulation process. A brief review of studies from diverse domains, including complex motor-skill representation, emotion perception, and face memory, highlights that emulation theory offers precise explanations of results and novel predictions. However, the neural instantiation of the emulation process requires development to move the theory from armchair to laboratory.
