Five experiments investigated how people use categories to make inductions about objects whose categorisation is uncertain. Normatively, they should consider all the categories the object might be in and use a weighted combination of information from all the categories: bet-hedging. The experiments presented people with simple, artificial categories and asked them to make an induction about a new object that was most likely in one category but possibly in another. The results showed that the majority of people focused on the (...) most likely category in making inductions, although there was a group of consistently normative responders who used information from both categories (about 25% of our college population). Across experiments the overall pattern of results suggests that performance in the task is improved not by understanding the underlying principles of bet-hedging but by increasing the likelihood that multiple categories are in working memory at the time of the induction. We discuss implications for improving everyday inductions. (shrink)

Six experiments investigated variables predicted to influence subjects’ tendency to classify items by a single property instead of overall similarity, following the paradigm of Norenzayan et al., who found that European Americans tended to give more “logical” rule-based responses. However, in five experiments with Mechanical Turk subjects and undergraduates at an American university, we found a consistent preference for similarity-based responding. A sixth experiment with Korean undergraduates revealed an effect of instructions, also reported by Norenzayan et al., in which classification (...) instructions led to majority rule-based responding but similarity instructions led to overall similarity grouping. Our American subjects showed no such difference and used similarity more overall. We conclude that Americans do not have a preference for rule responding in classification and discuss the differences between tasks that reliably show strong rule or unidimensional preferences in contrast to this classification paradigm.

The problems that Millikan addresses in theories of concepts arise from an extensional view of concepts and word meaning. If instead one assumes that concepts are psychological entities intended to explain human behavior and thought, many of these problems dissolve.

Research on children's and adults' concepts embodies very different assumptions of how concepts are structured, as reflected in their experimental designs. Developmental studies seem to assume that categories contain highly similar objects that can all be identified from one or two examples. If concepts are more like those tested in adult experiments, research on word learning may be misleading.

In his enormously influential The Modularity of Mind, Jerry Fodor (1983) proposed that the mind was divided into input modules and central processes. Much subsequent research focused on the modules and whether processes like speech perception or spatial vision are truly modular. Much less attention has been given to Fodor's writing on the central processes, what would today be called higher‐level cognition. In “Fodor's First Law of the Nonexistence of Cognitive Science,” he argued that central processes are “bad candidates for (...) scientific study” and would resist attempts at empirical analysis. This essay evaluates his argument for this remarkable claim, concluding that although central processes may well be “messier” than input modules, this does not mean that they cannot be studied and understood. The article briefly reviews the scientific progress made in understanding central processes in the 35 years since the book was published, showing that Fodor's prediction is clearly falsified by massive advances in topics like decision making and analogy. The essay concludes that Fodor's Law was not based on a clear argument for why the complexities of central systems could not be studied but was likely based on intuitions and preferences that were common in psychology at the time.

Death is the destiny we all share, and this will not change. Yet the way we die, which had remained the same for many generations, has changed drastically in a relatively short time for those in developed countries with access to healthcare. For generations, if people were lucky enough to reach old age, not having died in infancy or childhood, in childbirth, in war, or by accident, they would take to bed, surrounded by loved ones who cared for them, and (...) fade into death. Most likely, they would have seen their parents and grandparents die the same way, and so this manner of dying would be familiar: it was part of the natural cycle of life. Now less than 25 per cent of Americans die at home, having reached much older ages than people would have dreamed of in past generations, often after surviving many illnesses and even diseases that would have been terminal for their grandparents. We are fortunate to live (and die) today, supported by myriad scientific, medical, and technological advancements, however we also face new problems as a result of the new way in which we die. We can no longer anticipate a peaceful waning at home with family. We know our lives will likely end in hospitals likely after we have endured grueling treatments to prolong life. We have to decide what decisions we want our loved ones, or care-givers, to make when we cannot choose for ourselves. We have to think about whether in any circumstances we would seek physician-assisted death. We know we face other questions as well, but we may not even know where to start. In the face of these decisions, we can feel daunted and afraid. The best remedy is information and planning. In this book, Gregory Eastwood - a physician who has cared for dying patients, served as an ethics consultant, and taught end of life issues to medical and other health profession students - draws from his substantial experience with patients and families to provide the information that will help us think clearly about the choices and issues we will face at the end of our own lives, and when faced with the deaths of our loved ones. With sensitivity and profound insight, Eastwood guides us through all the important questions about death and dying in straightforward, clear language, enhanced by real-life stories. Throughout, he shows us how we can take ownership of the way we want to die, when we must die, and feel more in control as death approaches. (shrink)

This chapter focuses on one of the common fallacies in Western philosophy, appeal to ridicule. An appeal to ridicule is closely related to an ad hominem argument because both attack the person. There is a similarity between an appeal to ridicule and an appeal to emotion in that both attempt to bypass rational assessment of a point of view and elicit an emotional reaction from the audience. An appeal to ridicule may be an attempt to elicit humor at another's expense, (...) or it may be an attempt to elicit enmity, playing on the fears and prejudices of the group. The difference between a reductio ad absurdum and an appeal to ridicule is that the former uses good evidence while the latter does not. Perhaps the best way to avoid this fallacy is to cultivate an attitude of respect for other points of view. (shrink)

This paper describes a presentation on ethics for accounting and business students. In 2001 and 2002, major corporate failures such as Enron and Worldcom, combined with questionable accounting practices, made ethics a paramount concern to persons working in business and accounting. While financial statement analysis and regulatory requirements are important technical topics, the issue of ethics provides faculty a unique and very appropriate setting to discuss deeper truths about doing business and living life well. This paper briefly describes the development (...) and assessment of one approach to presenting ethics built around a computerized slide show (PowerPoint). The goal of the presentation is to increase students’ understanding of the essential role of ethics to accounting and business. Following the presentation, students indicated a heightened recognition of the importance of ethics. Educators should do all that they can to encourage students to do the “right” thing, even in difficult circumstances. This encouragement may serve them well in school and later in their careers.

When a structure or class of structures admits an unbounded induction, we can do arithmetic on the stages of that induction: if only bounded inductions are admitted, then clearly each inductively definable relation can be defined using a finite explicit expression. Is the converse true? We examine evidence that the converse is true, in positive elementary induction . We present a stronger conjecture involving the language L consisting of all L∞ω formulas with a finite number of variables, and examine a (...) combinatorial property equivalent to “all L-definable relations are elementary”.

We present game-theoretic characterizations of the complexity/expressibility measures “dimension” and “the number of variables” as Least Fixed Point queries. As an example, we use these characterizations to compute the dimension and number of variables of Connectivity and Connectivity.

It is known that for two given countable sets of unary relations A and B on ω there exists an infinite set H ⫅ ω on which A and B are the same. This result can be used to generate counterexamples in expressibility theory. We examine the sharpness of this result.

We prove that any positive elementary (least fixed point) induction expressing the negation of transitive closure on finite nondirected graphs requires at least two recursion variables.

Leave No Trace (LNT) has become the official education and outreach policy for managing recreational use in parks and wilderness areas throughout the United States. It is based on seven core principles that seek to minimize impacts from backcountry recreational activities such as hiking, climbing, and camping. In this paper, we review the history and current practice of Leave No Trace in the United States, including its complex role in the global political economy of outdoor recreation. We conclude by suggesting (...) a new framework for building on the successes of Leave No Trace, while moving beyond its self-imposed limitations, and recapturing wilderness recreation as a more collaborative, participatory, productive, democratic, and radical form of political action.

Accounting educators are being called on to provide a greater emphasis on ethics education. This paper examines three important issues concerning ethics education in accounting. First, the question of whether ethics can indeed be taught is examined. Next, several innovative approaches are presented which have been used by accounting educators to integrate ethics into the classroom. Finally, results of a survey of students concerning their perspectives of ethical issues in accounting education, the accounting profession, and society at large are presented (...) and discussed. Survey results reveal that students consider a lack of ethics damaging to the accounting profession and society. Results also indicate that accounting students are seeking ethical and moral direction. (shrink)

This paper explores the scriptural and theological reasons given by Jehovah's Witnesses (JWs) to refuse blood transfusions. Julian Savulescu and Richard W Momeyer argue that informed consent should be based on rational beliefs and that the refusal of blood transfusions by JWs is irrational, but after examining the reasons given by JWs, I challenge the claim that JW beliefs are irrational. I also question whether we should give up the traditional notion of informed consent.

The charges of fideism and relativism have long been leveled against Wittgensteinian philosophy of religion. However, the philosopher most influenced by Wittgenstein's understanding of religion, D. Z. Phillips, is guilty of neither fideism nor conceptual scheming. The contribution of Wittgenstein to an understanding of religious belief is much more nuanced than critics generally appreciate. Likewise, the relationship of Wittgenstein's philosophy to that of Davidson and to pragmatism, especially in its Rortyan manifestations, is shown to be friendlier than is often recognized.
