This paper develops a modal, Sentential logic having "not", "if...Then" and necessity as logical constants. The semantics (system of meanings) of the logic is the most obvious generalization of the usual truth-Functional semantics for sentential logic and its deductive system (system of demonstrations) is an obvious generalization of a suitable (jaskowski-Type) natural deductive system for sentential logic. Let a be a set of sentences and p a sentence. "p is a logical consequence of a" is defined relative to the semantics (...) and "p is demonstrable from a" is defined relative to the deductive system. Main meta-Theorem: p is demonstrable from a if and only if p is a logical consequence of a. Henkin-Type methods are used. The theorems of the logic are exactly those of s5. The deductive system is rigorously developed as a system of linear strings. (shrink)

What kind of persons could engage in political torture? Not only the morally impaired who lack empathy or compassion, or even the merely obedient, but also the righteous who struggle with conscience, and the realists who set morality aside.

This essay defines and critiques ‘methodocentrism’, the belief that predetermined research methods are the determining factor in the validity and importance of educational research. By examining research in science studies and posthumanism, the authors explain how this methodocentrism disenables research from taking account of problems and non-human actants that are presumed to be of no importance or value in existing social science research methodologies, both qualitative and quantitative. Building from a critique of these methods as profoundly anthropocentric, the authors examine (...) three crucial problematics in which methodocentrism functions in educational research: the institutionalization of graduate training, a wide-spread privileging of the visual, and the seeming necessity of ‘data’ in social scientific research methodologies. Ultimately, this article does not reject the necessity of particular studies having methods—rigorous, philosophically grounded approaches to problems in the world—but it argues that the belief that methods must be selected from existing options and assembled before approaching the ‘objects’ of study is not only a form of bad science, it is also deeply implicated in anthropocentric and colonialist politics. Instead, what research requires today is a thorough rethinking of the very distinction between subject and object and a renewed questioning of how agency functions in specific research settings.

We report on the small-scale (0.5 13 h - 1M, a large-scale bias of ~2.0 and a satellite fraction of 12 ± 2 per cent. Thus, these galaxies occupy haloes with average masses in between those of the higher redshift BOSS CMASS sample and the original SDSS I/II luminous red galaxy sample © 2012 The Authors Published by Oxford University Press on behalf of the Royal Astronomical Society © doi:10.1093/mnras/sts314.

Philosophers who have written on modesty have largely agreed that it is a virtue, and that it therefore has an important psychological component. Mere modest behavior, it is often argued, is actually false modesty if it is generated by the wrong kind of mental state. The philosophical debate about modesty has largely focused on the question of which kind of mental state—cognitive, motivational, or evaluative—best captures the virtue of modesty. We therefore conducted a series of experiments to see which philosophical (...) account matches the folk concept of modesty. Surprisingly, we found that the folk concept is primarily behavioral. This leads us to argue that modesty may not be a virtue, but that if it is none of the extant philosophical accounts have properly explained why. (shrink)

These original essays offer new perspectives for science educators, curriculum theorists, and cultural critics on science education, French post-structural thought, and the science debates. Included in this book are chapters on the work of Bruno Latour, Michel Serres, and Jean Baudrillard, plus chapters on postmodern approaches to science education and critiques of modern scientific assumptions in curriculum development.

From ancient times to the present, the discovery and presentation of new proofs of previously established theorems has been a salient feature of mathematical practice. Why? What purposes are served by such endeavors? And how do mathematicians judge whether two proofs of the same theorem are essentially different? Consideration of such questions illuminates the roles that proofs play in the validation and communication of mathematical knowledge and raises issues that have yet to be resolved by mathematical logicians. The Appendix, in (...) which several proofs of the Fundamental Theorem of Arithmetic are compared, provides a miniature case study. (shrink)

This essay examines how the American Jewish Congress (AJC) designed a legal attack on discrimination based on social science. This campaign led to the creation in 1945 of two new AJC commissions, t...

Philosophical defenses of cognitive/evolutionary psychological accounts of racialism claim that classification based on phenotypical features of humans was common historically and is evidence for a species-typical, cognitive mechanism for essentializing. They conclude that social constructionist accounts of racialism must be supplemented by cognitive/evolutionary psychology. This article argues that phenotypical classifications were uncommon historically until such classifications were socially constructed. Moreover, some philosophers equivocate between two different meanings of “racial thinking.” The article concludes that social constructionist accounts are far more robust (...) than psychological accounts for the origins of racialism.

Despite what Peter Singer and Peter Unger believe, no one violates the ‘rescue principle’ when she makes a frivolous purchase instead of giving to a charity like UNICEF. Nor does any one violate a collective action version of the rescue principle when she makes a frivolous purchase instead of giving to a charity. Garrett Cullity is also mistaken in believing that ‘the transitivity of wrongness’ can be used to reach the conclusion that a failure to give to charity is wrong (...) because a failure to save is. This makes it likely that the requirement to give to charity is based not on the requirement to rescue but instead on the moral requirement to marginally improve the ability of charitable organisations to do their important work.
