ABSTRACT Drawing inspiration from Fred Dretske, L. S. Carrier, John A. Barker, and Robert Nozick, we develop a tracking analysis of knowing according to which a true belief constitutes knowledge if and only if it is based on reasons that are sensitive to the fact that makes it true, that is, reasons that wouldn’t obtain if the belief weren’t true. We show that our sensitivity analysis handles numerous Gettier-type cases and lottery problems, blocks pathways leading to skepticism, and validates (...) the epistemic closure thesis that correct inferences from known premises yield knowledge of the conclusions. We discuss the plausible views of Ted Warfield and Branden Fitelson regarding cases of knowledge acquired via inference from false premises, and we show how our sensitivity analysis can account for such cases. We present arguments designed to discredit putative counterexamples to sensitivity analyses recently proffered by Tristan Haze, John Williams and Neil Sinhababu, which involve true statements made by untrustworthy informants and strange clocks that sometimes display the correct time while running backwards. Finally, we show that in virtue of employing the paradox-free subjunctive conditionals codified by Relevance Logic theorists instead of the paradox-laden subjunctive conditionals codified by Robert Stalnaker and David Lewis.

In a recent very interesting and important challenge to tracking theories of knowledge, Williams & Sinhababu claim to have devised a counter-example to tracking theories of knowledge of a sort that escapes the defense of those theories by Adams & Clarke. In this paper we will explain why this is not true. Tracking theories are not undermined by the example of the backward clock, as interesting as the case is.

Happiness can be expressed through smiles. Happiness can also be expressed through physical displays that without context, would appear to be sadness and anger. These seemingly incongruent displays of happiness, termed dimorphous expressions, we propose, represent and communicate expressers’ motivational orientations. When participants reported their own aggressive expressions in positive or negative contexts, their expressions represented positive or negative emotional experiences respectively, imbued with appetitive orientations. In contrast, reported sad expressions, in positive or negative contexts, represented positive and negative emotional (...) experiences respectively, imbued with consummatory orientations. In six additional experiments, participant observers interpreted that aggression displayed in positive contexts signalled happy-appetitive states, and sadness displayed in positive contexts signalled happy-consummatory states. Implications for the production and interpretation of emotion expressions are discussed. (shrink)

Musical Perceptions is a much-needed text that introduces students of both music and psychology to the study of music perception and cognition. Because the book aims to foster a closer interaction between research in the science and the art of music, both psychologists and musicians contribute chapters on a wide range of topics, including the philosophy of music; research in musical performance; perception of melody, tonality, and rhythm; pedagogical issues; language and music; and neural networks. With their unique ability to (...) introduce musical and psychological concepts to first-time students in the area, Rita Aiello and John Sloboda have edited a volume that will be popular with undergraduate and graduate students taking courses in the perception, psychology, and aesthetics of music. They have prefaced each chapter with an introduction to the chapter's research. This book will also be useful to cognitive and physiological psychologists and music theorists interested in music perception. (shrink)

The mechanisms responsible for the fine tuning of development, where the wildtype phenotype is reproduced with high fidelity, are not well understood. The difficulty in approaching this problem is the identification of mutant phenotypes indicative of a defect in these fine‐tuning control mechanisms. Evolutionary biologists have used asymmetry as a measure of developmental homeostasis. The rationale for this was that, since the same genome controls the development of the left and right sides of a bilaterally symmetrical organism, departures from symmetry (...) can be used to measure genetic or environmental perturbations. This paper examines the relationship between asymmtry and resistance to organophosphorous insecticides in the Australian sheep blowfly, Lucilia cuprina. A resistance gene, Rop‐1, which encodes a carboxylesterase enzyme, also confers a significant increase in asymmetry. Continued exposure of resistant populations to insecticide has selected a dominant suppressor of the asymmetry phenotype. Genetic evidence indicates that the modifier is the L. cuprina Notch homologue. (shrink)

The radical nub of Byrne & Russon's argument is that passive priming effects can produce much of the evidence of higher-order cognition in nonhuman primates. In support of their position we review evidence of similar behavioral priming effects n humans. However, that evidence further suggests that even program-level imitative behavior can be produced through priming.

Understanding the intersections of science and publics has led to research on how diverse publics interpret scientific information and form positions on science-related issues. Research demonstrates that attitudes toward science, political and religious orientation, and other social factors affect adult interactions with science, which has implications for how adults influence K-12 STEM (science, technology, engineering, and mathematics) education. Based on a statewide survey of adults in Idaho (n = 407), a politically and religiously conservative western state, we demonstrate how attitudes (...) toward science, measured through a composite measure “orientation toward science,” and other social factors are correlated with support for STEM education. Results show that “orientation toward science,” along with political orientation and respondents’ perceptions of feeling informed about science, predicts behavior intentions to support STEM education. Our findings suggest that a nuanced and localized approach to fostering support for K-12 STEM education would resonate with populations regardless of political orientation, and they illuminate new ways of thinking about how political orientation more generally impacts thinking about science in the context of complicated “socio-scientific relations.” In exploring how people think about science in a politically and religiously conservative state, we provide insights on potential outcomes in other states, should conservative ideology spread. We argue that the publics’ relationship with science and, by extension, support for science education, is more fluid, as many of us suspect, than ideological polemics suggest. (shrink)

Ernest Gellner was a multilingual polymath who set the agenda in the study of nationalism and the sociology of Islam for an entire generation of academics and students. This definitive biography follows his trajectory from his early years in Prague, Paris and England to international success as a philosopher and public intellectual. Known both for his highly integrated philosophy of modernity and for combining a respect for nationalism with an appreciation for science, Gellner was passionate in his defence of reason (...) against every for of relativism.

In Democratic Reason, Hne Landemore has built a case for the epistemic virtues of inclusive deliberative democracy based on the cognitive diversity of the group engaged in making collective decisions. She supports her thesis by appealing to the Diversity Trumps Ability Theorem of Lu Hong and Scott Page. This theorem is quite technical and the informal statements of it aimed at democratic theorists are inaccurate, which has resulted in some misguided critiques of the theorem's applicability to democratic politics. This paper (...) provides an exposition of the Diversity Trumps Ability Theorem that does not sacrifice precision for accessibility. It also shows that it is not possible to satisfy the assumptions of this theorem when there are only two options. Thus, the Diversity Trumps Ability Theorem cannot provide support for the epistemic virtues of inclusive democratic deliberation for binary collective decisions. (shrink)

"The book provides an excellent historical summary of the debates over continental drift theory in this century." —Contemporary Sociology "This is a useful discussion of the way that science works. The book will be of value to philosophers of science... " —Choice "... will find an important place in university and department libraries, and will interest afficionados of the factual and intellectual history of the earth sciences." —Terra Nova "... an excellent core analysis... " —The Times Higher Education Supplement "... (...) an ambitious and important contribution to the new sociology of science." —American Journal of Sociology "... Stewart's book is a noble effort, an interesting and readable discussion, and another higher notch on the scoreboard of critical scholarship that deserves wide examination and close attention." —Geophysics This fascinating book describes the rise and fall and rebirth of continental drift theory in this century. It uses the recent revolution in geoscientinsts' beliefs about the earth to examine questions such as, How does scientific knowledge develop and change? The book also explores how well different perspectives help us to understand revolutionary change in science. (shrink)

Embodied cognitive science holds that cognitive processes are deeply and inescapably rooted in our bodily interactions with the world. Our finite, contingent, and mortal embodiment may be not only supportive, but in some cases even constitutive of emotions, thoughts, and experiences. My discussion here will work outward from the neuroanatomy and neurophysiology of the brain to a nervous system which extends to the boundaries of the body. It will extend to nonneural aspects of embodiment and even beyond the boundaries of (...) the body to prosthetics of various kinds, including symbioses with a broad array of cultural artifacts, our symbolic niche, and our relationships with other embodied human beings. While cognition may not always be situated, its origins are embedded in temporally and spatially limited activities. Cognitive work also can be off-loaded to the body and to the environment in service of action, tool use, group cognition, and social coordination. This can blur the boundaries between brain areas, brain and body, and body and environment, transforming our understanding of mind and personhood to provide a different grounding for faith traditions in general, and of the historically dualist Christian tradition in particular.

Some irrational numbers are "random" in a sense which implies that no algorithm can compute their decimal expansions to an arbitrarily high degree of accuracy. This feature of (most) irrational numbers has been claimed to be at the heart of the deterministic, but chaotic, behavior exhibited by many nonlinear dynamical systems. In this paper, a number of now classical chaotic systems are shown to remain chaotic when their domains are restricted to the computable real numbers, providing counterexamples to the above (...) claim. More fundamentally, the randomness view of chaos is shown to be based upon a confusion between a chaotic function on a phase space and its numerical representation in Rn. (shrink)

As genomic science has evolved, so have policy and practice debates about how to describe and evaluate the ways in which genomic information is treated for individuals, institutions, and society. The term genetic exceptionalism, describing the concept that genetic information is special or unique, and specifically different from other kinds of medical information, has been utilized widely, but often counterproductively in these debates. We offer genomic contextualism as a new term to frame the characteristics of genomic science in the debates. (...) Using stasis theory to draw out the important connection between definitional issues and resulting policies, we argue that the framework of genomic contextualism is better suited to evaluating genomics and its policy-relevant features to arrive at more productive discussion and resolve policy debates.

The common autoimmune disease type 1 diabetes provides a paradigm for the genetic analysis of multifactorial disease. Disease occurrence is attributable to the interaction with the environment of alleles at many loci interspersed throughout the genome. Their mapping and identification is difficult because the disease-associated alleles occur almost as commonly in patients as in healthy individuals; even the highest-risk genotypes bestow only modest risks of disease. The identification of common quantitative trait loci (QTL) in autoimmune disease and in other common (...) disorders, therefore,requires a very close marriage of genetics and biology. Two QTLs have been identified in human type 1 diabetes: the major histocompatibility complex HLA class II loci and a promoter polymorphism of the insulin gene. The evidence for their primary roles in disease aetiology demonstrates the necessity of combined studies of genetics and biology. Their functions and interaction underpin an emerging picture of the basic causes of the disease and direct analyses towards other candidate genes and pathways. The genetic tools used for QTL identification include transgenesis and gene knockouts, whole genome scanning for linkage, mouse congenic strains, linkage disequilibrium mapping, and the establishment of ancestral haplotypes among disease-associated chromosomes.

In Eco’s work between around 1960 and 1992, “openness” in a modern literary text can mean (a) “permitting more than one interpretation,” and (b) “requiring a good deal of decoding work from the reader,” which is close to my own position. These two aspects of openness are demonstrated using Baudelaire’s Les Chats, in regard to which Eco denies that the text may be cristallin in Lévi-Strauss’s sense, while still requiring constructive effort from the reader. It is apparent that this term (...) is equivalent to Riffaterreʼs textual “monumentality.” Eco does not go into detail about the reader’s work in assembling the text’s global propositional structure. It is left to Riffaterre and myself to detail the various stages of this work, involving comparison of images in order to discover their common underlying generative proposition. In contrast to Riffaterre, I have long suggested that the modern poetic text is built on two such propositions. It is at the stage of relations between text and sociolect that Eco contributes much to modern poetics. Openness (b) seems to be a prerequisite for perceptual change in the reader, produced by contrast between textual structure and its sociolectic context. Riffaterre prefers to remain within the text/intertext/interpretant triad, preventing him from describing the text-sociolect relation, where the propositional innovation of the modernist text takes effect.
