This paper proposes an account of mathematical reasoning as parallel in structure: the arguments which mathematicians use to persuade each other of their results comprise the argumentational structure; the inferential structure is composed of derivations which offer a formal counterpart to these arguments. Some conflicts about the foundations of mathematics correspond to disagreements over which steps should be admissible in the inferential structure. Similarly, disagreements over the admissibility of steps in the argumentational structure correspond to different views about mathematical practice. (...) The latter steps may be analysed in terms of argumentation schemes. Three broad types of scheme are distinguished, a distinction which is then used to characterize and evaluate four contrasting approaches to mathematical practice. (shrink)

Fake news sharing in 2016 was rare but significantly more common among older Americans. So-called “fake news” has renewed concerns about the prevalence and effects of misinformation in political campaigns. Given the potential for widespread dissemination of this material, we examine the individual-level characteristics associated with sharing false articles during the 2016 U.S. presidential campaign. To do so, we uniquely link an original survey with respondents’ sharing activity as recorded in Facebook profile data. First and foremost, we find that sharing (...) this content was a relatively rare activity. Conservatives were more likely to share articles from fake news domains, which in 2016 were largely pro-Trump in orientation, than liberals or moderates. We also find a strong age effect, which persists after controlling for partisanship and ideology: On average, users over 65 shared nearly seven times as many articles from fake news domains as the youngest age group.

An overview of analytic philosophy of music.

Decoherence results from the dissipative interaction between a quantum system and its environment. As the system and environment become entangled, the reduced density operator describing the system "decoheres" into a mixture (with the interference terms damped out). This formal result prompts some to exclaim that the measurement problem is solved. I will scrutinize this claim by examining how modal and relative-state interpretations can use decoherence. Although decoherence cannot rescue these interpretations from general metaphysical difficulties, decoherence may help these interpretations to (...) pick out a preferred basis. I will explore whether decoherence solves nagging technical problems associated with selecting a preferred basis. (shrink)

The writings of William H. Whyte do not loom large in the literature of my field: environmental ethics, the branch of ethics devoted to consideration of whether and how there are moral reasons for protecting non-human animals and the larger natural environment. Environmental ethics is a very new field of inquiry, only found in academic philosophy departments since the early 1970s. While there is no accepted reading list of indispensable literature in environmental ethics, certainly any attempt to create such a (...) list would begin with Henry David Thoreau, John Muir, Aldo Leopold, Rachel Carson, and a more recent handful of senior scholars who had been writing on these topics early on, such as J. Baird Callicott, Val Plumwood, Peter Singer, Richard Sylvan, Tom Regan, and Holmes Rolston III (for a review of contemporary environmental ethics, see Light 2002, Palmer 2003, and Wenz 2001).

Charles Stevenson introduced the term 'persuasive definition’ to describe a suspect form of moral argument 'which gives a new conceptual meaning to a familiar word without substantially changing its emotive meaning’. However, as Stevenson acknowledges, such a move can be employed legitimately. If persuasive definition is to be a useful notion, we shall need a criterion for identifying specifically illegitimate usage. I criticize a recent proposed criterion from Keith Burgess-Jackson and offer an alternative.

Objective: The value of spontaneous EEG oscillations in distinguishing patients in vegetative and minimally conscious states was studied. Methods: We quantified dynamic repertoire of EEG oscillations in resting condition with closed eyes in patients in vegetative and minimally conscious states (VS and MCS). The exact composition of EEG oscillations was assessed by the probability-classification analysis of short-term EEG spectral patterns. Results: The probability of delta, theta and slow-alpha oscillations occurrence was smaller for patients in MCS than for VS. Additionally, only (...) patients in MCS demonstrated fast-alpha oscillation occurrence. Depending on the type and composition of EEG oscillations, the probability of their occurrence was either aetiology dependent or independent. The probability of EEG oscillations occurrence differentiated brain injuries with different aetiologies. Conclusions: Spontaneous EEG oscillations have a potential value in distinguishing patients in VS and MCS. Significance: This work may have implications for clinical care, rehabilitative programs and medical–legal decisions in patients with impaired consciousness states following coma due to acute brain injuries.

'Incommensurability' has, in the last forty years, gained wide currency in the literature of philosophy. Kuhn and Feyerabend used the term in the early 1960's to describe an issue in the philosophy of science. They suggested that, when scientific theories are introduced that are significantly different from their predecessors, it may happen that the meanings of key terms differ significantly, and to the extent that scientists may be unable to fully comprehend the new theory until they experience a form of (...) radical conversion, in which they come to fully grasp the new theory. Key contributions have been made to this literature by Bishop, Devitt, Margolis, Sankey, and Scheffler. ;The notion of 'incommensurability' has also been widely used in discussions of ethics. Finnis has used the concept to effect a taxonomy of human values, arguing that there are seven such values and that incommensurability is the feature that contradistinguishes them. Key contributions have been made to this literature by Goodman, Griffin, Pannier, Raz, and Williams. ;In this work I discuss the literature of incommensurability in both the philosophy of science and ethics. I argue that there are at least two quite different notions of incommensurability: one is a well defined notion originally used by mathematicians; the other, less well defined, means, based on the etymology of the word, lacking a common measure. I argue, further, that the discussions of Kuhn and Feyerabend are based on the mathematical notion, while the discussions in ethics are based on the etymological notion. ;Further complicating the discussions in both ethics and the philosophy of science, is the connection between the notions of commensurability and comparability. I argue that the notions describe, differently, equivalent sets. ;Ultimately Kuhn's notion fails because he cannot resolve his arguments for both inexpressibility in a common language and for comparability of competing theories. Finnis's notion fails because incommensurability does not, in fact, uniquely describe the taxonomy for which he argues. (shrink)

A solution to the Liar must do two things. First, it should say exactly which step in the Liar reasoning - the reasoning which leads to a contradiction - is invalid. Secondly, it should explains why this step is invalid.

An essay on Pietro Pomponazzi, the philosopher and founder of the Aristotelian-Averroistic School. His great work De immortalitate animi, gave rise to a storm of controversy between the orthodox Thomists of the Catholic Church, the Averroists headed by Agostino Nifo, and the so-called Alexandrist School. The treatise was burned at Venice, and Pomponazzi himself ran serious risk of death at the hands of the Catholics. Two pamphlets followed, the Apologia and the Defensorium, wherein he explained his paradoxical position as Catholic (...) and philosophic materialist. His last two treatises, the De incantationibus and the De fato, were posthumously published in an edition of his works printed at Basel. Chapters: Aristotle in the Early Middle Ages; The Arabians and St. Thomas; Pomponazzi as an Aristotelian; Pomponazzi's Psychology; The Soul; Intelligence; Sense; Reason; Knowledge; The Nature of Virtue; and Natural Law in Human Life and Religion.
