Interest in science and math plays an important role in encouraging STEM motivation and career aspirations. This interest decreases for girls between late childhood and adolescence. Relatedly, positive mentoring experiences with female teachers can protect girls against losing interest. The present study examines whether visitors to informal science learning sites differ in their expressed science and math interest, as well as their science and math stereotypes following an interaction with either a male or female educator. Participants were visitors to one (...) of four ISLS in the United States and United Kingdom. Following an interaction with a male or female educator, they reported their math and science interest and responded to math and science gender stereotype measures. Female participants reported greater interest in math following an interaction with a female educator, compared to when they interacted with a male educator. In turn, female participants who interacted with a female educator were less likely to report male-biased math gender stereotypes. Self-reported science interest did not differ as a function of educator gender. Together these findings suggest that, when aiming to encourage STEM interest and challenge gender stereotypes in informal settings, we must consider the importance of the gender of educators and learners.

This report describes the rationale, approaches, organization, and resource development leading to a large-scale deletion bin map of the hexaploid wheat genome. Accompanying reports in this issue detail results from chromosome bin-mapping of expressed sequence tags representing genes onto the seven homoeologous chromosome groups and a global analysis of the entire mapped wheat EST data set. Among the resources developed were the first extensive public wheat EST collection. Described are protocols for sequencing, sequence processing, EST nomenclature, and the assembly of (...) ESTs into contigs. These contigs plus singletons were used for selection of distinct sequence motif unigenes. Selected ESTs were rearrayed, validated by 5′ and 3′ sequencing, and amplified for probing a series of wheat aneuploid and deletion stocks. Images and data for all Southern hybridizations were deposited in databases and were used by the coordinators for each of the seven homoeologous chromosome groups to validate the mapping results. Results from this project have established the foundation for future developments in wheat genomics. (shrink)

This chapter discusses various conceptions of moral judgment during the eighteenth century in Britain. It begins with a characterization of moral rationalism that centres on Samuel Clarke and John Locke. It then discusses moral sentimentalism or moral sense theory, which is associated with Shaftesbury, Hutcheson, and Hume, portraying it partly as a reaction to moral rationalism but also as a response to the perceived positions of Hobbes and Mandeville. The chapter then discusses the position of Joseph Butler, Adam Smith’s (...) sophisticated version of sympathy and sentimentalism, and the theories of Richard Price and Thomas Reid, both of which rejected sentimentalism.

Externalism holds, and internalism denies, that the individuation of many of an individual's mental states (e.g., thoughts about the physical world) depends necessarily on relations that individual bears to the physical and/or social environment. Many philosophers, externalists and internalists alike, believe that introspection yields knowledge of the contents of our thoughts that is direct and authoritative. It is not obvious, however, that the metaphysical claims of externalism are compatible with this epistemological thesis. Some (e.g., Burge, 1988; Falvey and Owens (F&O), (...) 1994) have sought to dispel the worry that there is a conflict, though they admit that if such a conflict exists, it spells trouble for externalism (see, e.g., F&O, 1994, p. 108). Boghossian has argued that there is indeed a conflict between externalism and introspective knowledge of content. Surprisingly, however, he also argues that there is a conflict between internalism and introspective knowledge of content. I will defend Boghossian's claim that there is a conflict between externalism and knowledge of content, but criticize his claim that there is a conflict between internalism and knowledge of content.

One of the issues with introducing animal rights law is whether the problem is quantitative or qualitative, whether it can be achieved by working within existing legal paradigms or whether it requires a new set of paradigms. The answer is fundamental: a quantitative problem can be solved by applying more of the same solutions, while a qualitative problem requires completely different solutions. The qualitative camp can be represented by, say, Professor Gary Francione, demanding not only rights for animals but that (...) they have personhood and are no longer considered “property.” The quantitative approach can be finely represented by Professor David Favre, who has argued for many years that we can make progress by developing existing legal principles to give some rights to some animals, and he does so eloquently in his new book. He is clear in his view that progress is, and can continue to be, made with a series of steps, as he puts it, “climbing the slippery slope toward personhood” (p. viii).His case is supported by looking backward—progress made in establishing the rules governing humans in their relationships with animals—as well as forward to developments that will support continuing improvement in the lives of animals, not least the potential for technology (for example, through cell- and plant-based meat). At the same time, he also rightly rejects the concepts of animal welfare and animal rights being at odds, let alone either of them being a panacea for better lives for animals.One aspect of animal law that Favre believes does need to change is that of property status. As he says, the status of animals as personal property is “critical to the future of animal law” (p. 25). In general, the solutions have been largely binary—that animals simply cannot be property for them to have meaningful rights or that animals can be property and still have rights. The former makes intuitive good sense (and is consistent with the objectives of the human abolitionist movements) but would have enormous effects on economic activity throughout the world. The latter is appealing because it does not change the current paradigm, so can be developed more easily.Favre's premise is that we are moving toward rights for animals, so we need to find a way of integrating animals into the current legal system rather than having to destroy and reconstruct the legal system. His ingenious solution is to propose a fourth category of property, alongside real, personal, and intellectual property: “living property.”Within this category, he envisages using the common law concept of the trust to provide equitable “self-ownership,” where an animal has equitable “ownership” while a human retains legal “ownership.” He then connects this concept to adaptations in other aspects of law that start to recognize the selfhood of animals, creating a platform onto which broader and deeper rights for animals can develop, such as the status of “animalhood” (p. 72) and the corresponding legal right of consideration before decisions are made by the state affecting an animal's fundamental interests (such as continuing to be alive). By putting animals in a separate class—rather than uncomfortably leaving them in personal property—he creates a possible route for animal rights that seems less paradigm-busting than removing them from being property altogether.Drawing on evidence from criminal law, tort law, equity (trusts), property law, and family law, he shows how in many places—with a focus on states in the United States—existing laws are being adapted (“green shoots” p. 81) to recognize that animals are more than personal property, in ways that cannot be explained simply through the growth of regulations. For example, family law is starting to recognize that in the division of matrimonial assets, companion animals cannot be treated simply like any other personal property such as a table or a car based on who paid for them. Because animals are “living property,” the courts should take account of other aspects, such as who cared for the animals and who looked after them. Similarly, the concept of extending trust law so that an animal can be the beneficiary of a trust—in the same way as a human can be but inanimate personal property cannot—shows that the law can understand that companion animals can play a large emotional role in our lives (as well as we in theirs), such that we want to ensure proper care for them after we die.The book raises important issues. First, it is intentionally about domestic animals, with their close links with humans, so the potential for laws to engage is much easier than with, say, farmed animals. The danger with solutions that focus on domestic or charismatic animals (e.g., dogs, chimpanzees, elephants) is that the arguments may be pertinent essentially only to those species and therefore hard to apply to animals of less charismatic species, say in a factory farm (but who are present in much greater numbers and generally badly treated in comparison). He “leaves for another day” (p. 32) the discussion about other animals. Hopefully that day will come, as it would be interesting to see how Favre could extend his concept to animals for whom the public has less affection and less appreciation of their capacities (and for whom the prospect of death is much more real and imminent).Secondly, public support for these ideas about living property may simply not be present. If there is not a sufficient groundswell of support for changing the status of animals, then whether one proposes changing it to not-property or “self-owned” property doesn't matter (if someone doesn't like needles, it doesn't matter whether the needle you propose to use is big or small). This may be too pessimistic, of course (people can be helped to overcome a fear of needles, and one way to start is with small needles). Perhaps the law should start with small changes to recognize at least a few animals—their sentience, their capacities for pleasure and pain, their emotions and preferences, their potential for autonomy—and build public support from there.There is also the underlying and more radical point about whether these ideas—the trust for a beloved companion set up by the human, the divorce settlement that doesn't just give the companion to the party who paid for them—are actually bringing about changes for animals as such or are simply adapting laws to help humans, recognizing human needs, and do not actually change the status of animals. The ends are still humans, and the means are still animals.This is not intended to paint a bleak picture: The more bluntand uncompromising part of the animal rights movement that has been focused on the qualitative problem has hardly been successful at getting animal rights laws passed anywhere in the world, so everything that moves us closer to a better, richer, more thoughtful view of animals will help. Favre's approach has ingenuity, shows good sense, and has the potential to bring about real animal rights. The themes and cases in this book that show how courts and legislatures are becoming more aware of the sentience of at least some animals, as well as proposing a middle path in the debate about animals as property, are important in the journey toward recognition of animal rights. Even more important, they may actually work. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:328 HUME, MIRACLES AND LOTTERIES This paper addresses recent criticisms of Hume's skepticism with regard to miracles, by 1 2 Sorensen and Hambourger who argue that there are counterexamples, illustrated by lotteries, to Hume's account of how the truth of reports of improbable events (either first or second hand) must be evaluated. They believe these counterexamples are sufficient to prove that Hume's argument against the believability of miracles, defined (...) as violations of laws of nature caused by God, is unsound. Their arguments merit consideration not only in their own right but also on the basis of historical precedent, since they have in common an assumption that is found in Butler's criticism of Hume's predecessors in this debate. The bulk of my paper deals with Hambourger, who presents the most detailed version of the 'Butler' criticism. Sorensen's version can be answered in light of the evaluation of Hambourger 's argument. Hume's Argument Hume's argument is not against the possibility of miracles but against the possibility that it could ever be reasonable to believe a miracle 4 had occurred. His argument can be summed up as follows: in judging the credibility of a report of an improbable event, the probability of the event must be weighed against the probability that the report could be mistaken. The probability of an event is determined by the degree to which it conforms to known laws of nature. Laws of nature are formulated on the basis of uniform experience. Assuming that a miracle is a violation of laws of nature, any judgment that an event is miraculous presupposes a 329 judgment that there exists a uniform pattern of causation to which it is opposed, which pattern would constitute empirical proof against the miracle's occurrence. Testimony, on the other hand, is shown by experience not to be uniformly reliable. Consequently, no report of a miracle will have credibility since there will always be a uniform experience that is full proof against it, which therefore outweighs whatever merits testimony may have. In Hume's words, [N]o testimony is sufficient to establish a miracle, unless the testimony be of such a kind, that its falsehood would be more miraculous, than the fact, which it endeavors to establish.... When anyone tells me, that he saw a dead man restored to life, I immediately consider with myself, whether it be more probable, that this person should either deceive or be deceived, or that the fact, which he relates, should really have happened.... If the falsehood of his testimony would be more miraculous, than the event which he relates; then, and not till- then, can he pretend to command my belief or opinion (E 115-116). Hambourger 's Criticism Hambourger maintains that Hume's argument depends on a principle which he calls the "principle of relative likelihood." He restates this principle as follows: Suppose that someone or, perhaps, a group of people testify to the truth of a proposition P that, considered by itself, is improbable. Then to evaluate the testimony, one must weight (sic) the probability that P is true against the probability that the informants are lying or mistaken. If it is more likely that P is true than that the informants are lying or mistaken, then, on balance, the 330 testimony renders P more likely than not, and it may be reasonable for one to believe that P. However, if it is as likely, or even more likely, that the informants are lying or mistaken than it is that P is true, then, on balance, the testimony does not render P more likely true than false, and it would not be,reasonable for one to believe that P. As a counterexample to this principle, Hambourger asks us to suppose that a lottery is held in which there are one million entrants, each of whom has a one in a million chance of winning, and that a reliable newspaper, the New York Times, reports that the winner of the lottery is Smith. He further asks us to suppose that the Times errs only once out of every 10,000 times. Thus, the probability that the Times ' report is wrong is... (shrink)

The readings, which cover most important work from Plato to Prichard, are arranged chronologically. Some selections, e.g., Butler's Dissertation on the Nature of Virtue, Kant's Foundations, and Mill's Utilitarianism, are reprinted in their entirety, and the other selections are lengthy enough for the student to get a clear view of a philosopher's ethical position. Two lacunae which existed in the previous edition, namely, from St. Augustine to Hobbes, and from Kant to Mill, are filled in this edition. In the (...) former, selections from Thomas Aquinas' Summa Theologiae are inserted to balance the chronology, and in the latter, selections from Nietzsche are included to give a better picture of the diversity of the nineteenth century. The book is not without its defects, however. St. Augustine's treatment of free will in the City of God has been deleted. Perhaps it would have been better if, instead of omitting this topic altogether, the editor had included some passages from Augustine's On the Free Choice of the Will, which contains a much better discussion of this issue. Also, the only selections from the twentieth century are parts of the first chapter of Moore's Principia Ethica, and Prichard's article "Does Moral Philosophy Rest on a Mistake?" Of course, everything cannot be included, but the latter two selections hardly bring the book up to date. However, in spite of the fact that one would have to supplement this text with additional material from twentieth century writings, Ethical Theories is still probably the most satisfactory available anthology for a treatment, via readings from the original writings, of the history of ethical philosophy.—G.

Abela accepts Fine’s account of realism and instrumentalism, but thinks that we can reject the Natural Ontological Attitude by distinguishing the theoretical attempt to make sense of scientific practice from choosing the attitude we bring to the debate, or to science itself. But Abela’s attitudes are vulnerable to Fine’s criticisms of the philosophical positions. However, if we take attitude as contrastive and as full‐blooded enough to lead to different behaviour we can see a gap in Fine’s position. He cannot tell (...) us why it is science that he trusts. When we look more widely, the philosophical positions might be seen as ways of justifying that trust. (shrink)

This book, first published in 1987, examines the notion of truth and then discusses knowledge and the way in which much of our knowledge revises or rejects the common-sense we start from. The author argues that our knowledge is not as secure as some would like to think and that there are important limits to the possibility for explanation. He shows how values permeate our ordinary thinking and argues against the objectivity of these values, showing the practical consequences of this (...) argument for teaching in schools. This stimulating approach to a fundamental educational issue does not require previous experience of formal philosophy and will be useful to both education students and teachers in schools. (shrink)

Michael Williams has frequently considered and rejected approaches to "our knowledge of the external world" that see it as the best explanation for certain features of experience. This paper examines the salience of his position to approaches such as Mackie’s that do not deny the presentational directness of ordinary experience but do permit a gap between how things appear and how they are that allows for sceptical doubts. Williams’ main argument is that, to do justice to its place in a (...) foundationalist strategy, the external world as hypothesis must offer an explicandum that does not invoke concepts of objects but is rather purely experiential. He next claims that no coherent regularities are available at such a level so there is nothing to be explained. Coherence only comes with objects, not as something objects could explain. Confronting this with Mackie’s Lockean theory of perception, we find that Mackie decisively rejects the first claim about the nature of the explicandum, since he sees ordinary perception as involving intentional objects which are distinct from the persisting objects they present. He is also committed to rejecting Williams’ line on purely experiential regularities, though this plays a subordinate role in his general position. The crucial issue then becomes the tenability of Mackie’s intentional object analysis and the extent to which it might yet tilt the argument in favour of realism against a global sceptic. In formulating his own epistemological strategies Williams might appear to countenance a version of Mackie’s view divorced from foundationalism. But while Williams’ contextualism in its minimal version might do so, in practice it retains the lessons derived from his skirmishes with scepticism and thus disallows certain types of enquiry. I conclude by contrasting Mackie’s response to scepticism with that of Williams in his diagnostic vein. (shrink)

Informal logicians recognise the frequent use of unstated assumptions; some (e.g. Fisher) also recognise entertained arguments and recommend a suppositional approach (such as Mackie's) to conditional statements. It is here argued that these two be put together to make argument diagrams more accurate and subtle. Philosophical benefits also accrue: insights into Jackson's apparent violations of modus tollens and contraposition and McGee's counterexamples to the validity of modus ponens.
