This essay is an analysis of conscious perception and conscious memory. It tries to show that percepts and mental images (roughly, experientially, the same as Hume's "impressions and ideas") are sets of particles at the perceived stimulus objects and at the remembered stimulus objects. It is thus a theory of direct perception and direct memory, and a materialism but not a central state materialism. The percept (we claim) is an "appearance" of the stimulus object particles (perceived object particles) which is due to the way the particles at the perceived object are interconnected (interrelated) by the networks of stimuli-plus-neuron-impulses starting from them. The same is true of the mental image. This essay is primarily an analysis of such networks--to show, we claim, how they make the sets of object particles seem to have sense qualities and gestalts and other properties of percepts and mental images.

The precise 1:1 segregation of Mendelian heredity is ordinarily taken for granted, yet there are numerous examples of ‘cheating’ genes that perpetuate themselves in the population by biasing the Mendelian process in their favor. One example is the Segregation Distortion system of Drosophila melanogaster, in which the distorting gene causes its homologous chromosome to produce a nonfunctional sperm. This system depends on three closely linked components, whose molecular basis is beginning to be understood.The system is characterized by numerous modifiers changing the degree of distortion. Mathematical theory shows that unlinked modifiers that change the degree of distortion in the direction of Mendelism always increase in the population. This provides a mechanism for removing cheaters and preserving the honesty of the Mendelian gene‐shuffle.

Most historians today have abandoned the aspiration to a kind of scientific objectivity in their work—pace their postmodernist critics. Yet we cling nonetheless, with a touch perhaps of hypocrisy, to the closely related standard of strict impartiality, or moral neutrality, in all that we do. This article argues that the latter is as obsolete, now, as the former—if only because of the distinctive though largely implicit moral character of almost all published history, all but the most technically specialized. The issue is not one of professional ethics, narrowly construed; obviously some such code must be maintained if history itself is to thrive. Rather historians are urged both to clarify the basic moral values that inevitably inform their work and to make more explicit, and thus intelligible, their ensuant moral judgments. They are also urged to discharge the task in a way that is commensurate with the pluralist, indeed global, challenges of our time. The implicit morality of conventional historical practice, in short, is no longer good enough

In lieu of an abstract, here is a brief excerpt of the content:Reviews 85 RUSSELL’S CONTRIBUTION TO PHILOSOPHY OF LANGUAGE James Connelly Philosophy, Trent U. Peterborough, on k9l 1z6, Canada [email protected] Graham Stevens. The Theory of Descriptions: Russell and the Philosophy of Language. Basingstoke, uk: Palgrave Macmillan, 2011. Pp. xiii, 197. isbn: 978-0230 -20116-3. £50; us$85. ver the past decade, Graham Stevens has built his reputation as a lucid, durable, and oftentimes ground-breaking historian of analytic philosophy. His latest book, entitled TheTheory of Descriptions: Russell and the Philosophy of Language, will only add to that burgeoning scholarly legacy. If it has not been established already, this book will doubtless cement Stevens’ place amongst the leading Russell scholars in the world today. It may very well herald Stevens ’ arrival on the scene as a noteworthy contributor to contemporary philosophy of language as well. The central goal of the book is “to bring the historical and purely philosophical analyses of [Russell’s] work into closer alignment” (p. 3). Stevens hopes to overcome a “striking disparity” (p. 2) in the ways that Russell’s contributions to the philosophy of language have been conceived by expositors of his philosophy, on the one hand, versus philosophers of language, on the other. In particular, though contemporary philosophers of language would tend to view Russell’s enormous contribution to that subject as being “undeniable” (p. 1), and to be “bewildered” (p. 94) by any suggestion to the contrary, expositors of Russell’s philosophy have nevertheless been at pains to emphasize that Russell “was not engaged in the philosophical study of language” (p. 2). As Stevens notes, this situation is especially puzzling since “these two groups [of scholars] overlap to a considerable extent” (p. 2). Stevens’ strategy for overcoming this disparity is two-pronged. First he aims to tackle, head on, the fallacious arguments of Monk,1 Dummett,2 and others, to the effect that Russell was not engaged in the philosophy of language. According to Stevens, such arguments have principally appealed to either (1) ______ 1 Ray Monk, “What Is Analytical Philosophy?”. 2 Michael Dummett, Frege: Philosophy of Language. l= 86 Reviews Russell’s dismissal of ordinary language philosophy, (2) his early, non-linguistic, conception of the nature of propositions, or (3) his view that natural language was inherently defective for philosophical purposes, and so called for replacement by a “logically perfect language”. In regards to (1), Stevens argues in a word that “[o]rdinary language philosophy has had its day” (p. 176). Over the past several decades, in other words, leading philosophers of language have come to agree with Russell in viewing ordinary language philosophy as “an outdated, and rather eccentric, relic of mid-twentieth century British philosophy” (ibid.).The classic Russell– Strawson debate over the question whether ordinary language lacks an exact logic3 has been settled decisively in Russell’s favour, as philosophers of language have transformed “the attempt to systematically specify the semantics of large regions of natural language” (ibid.) into a “central project” (ibid.). In regards to (2), moreover, Stevens notes that by this line of reasoning, absurdly, David Kaplan would not qualify as a philosopher of language since he “explicitly invokes the Russellian non-linguistic conception of a proposition as the conception appropriate for providing the content of properly context-situated indexical sentences” (p. 170). And, of course, Kaplan is not at all unique amongst contemporary philosophers of language in appealing to a Russellian conception of propositional content, as the examples of Nathan Salmon,4 Scott Soames,5 and many others show. In regards to (3), finally, Stevens argues that Russell’s dim view of natural language was grounded in his conception of logical form as non-linguistic, and that that conception, in turn, derives simply from the poverty of syntactic theory available to Russell, prior to the Chomskyian revolution in linguistics during the second half of the twentieth century. In light of the conceptual and analytic resources made available by this revolution, however, there exists “no insurmountable obstacle to assimilating Russell ’s notion of logical form to something akin to the modern notion of lf” (p. 172), where lf is conceived as one of four levels of syntactic representation within Chomsky’s Government and Binding Theory...

In the first decades of the twentieth century, a heterogeneous assortment of groups and individuals articulated scientific, political, and philosophical objections to vaccination. They engaged in an ongoing battle for public opinion with medical and scientific elites, who responded with their own counterpropaganda. These ideological struggles reflected fear that scientific advances were being put to coercive uses and that institutions of the state and civil society were increasingly expanding into previously private realms of decision making, especially child rearing. This essay analyzes the motivations and tactics of antivaccination activists and situates their actions within the scientific and social climate of the Progressive Era and the 1920s. Their actions reveal how citizens of varied ideological persuasions, activists and nonactivists alike, viewed scientific knowledge during a period of swift and unsettling change, when the application of biologic products seemed to hold peril as well as promise.
