Many philosophers accept both of the following claims: (1) consciousness matters morally, and (2) species membership doesn’t matter morally. In other words, many reject speciesism but accept what we might call 'sentientism'. But do the reasons against speciesism yield analogous reasons against sentientism, just as the reasons against racism and sexism are thought to yield analogous reasons against speciesism? This paper argues that speciesism is disanalogous to sentientism (as well as racism and sexism). I make a case for the following (...) asymmetry: (a) some non-humans clearly have interests, but (b) no non-conscious entities clearly have interests. This asymmetry, I argue, renders sentientism resistant to the standard argument against speciesism. (shrink)

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)

Heidegger's later thought is a thinking of things, so argues Andrew J. Mitchell in The Fourfold. Heidegger understands these things in terms of what he names "the fourfold"--a convergence of relationships bringing together the earth, the sky, divinities, and mortals--and Mitchell's book is the first detailed exegesis of this neglected aspect of Heidegger's later thought. As such it provides entré to the full landscape of Heidegger's postwar thinking, offering striking new interpretations of the atomic bomb, technology, plants, animals, weather, (...) time, language, the holy, mortality, dwelling, and more. What results is a conception of things as ecstatic, relational, singular, and, most provocatively, as intrinsically tied to their own technological commodification. A major new work that resonates beyond the confines of Heidegger scholarship, The Fourfold proposes nothing less than a new phenomenological thinking of relationality and mediation for understanding the things around us.

I discuss whether "sentience" (i.e., phenomenal consciousness) comes in degrees.

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.

An overview of analytic philosophy of music.

'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)

This essay first discusses the structure of the film (Memento_ (Christopher Nolan, 2000), its status as a neo-noir, and the implications of its accompanying website for its ontology. It then considers two clusters of philosophical themes in the film: the nature of mind and memory, and freedom, personal identity, and moral responsibility;.

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.

This paper considers the application to mathematical fallacies of techniques drawn from informal logic, specifically the use of ”argument schemes’. One such scheme, for Appeal to Expert Opinion, is considered in some detail.

This article charts a path between those who champion the culture concept and those who think it dangerous. This path navigates between two positions: realists who adopt realist conceptions of both the culture concept and the category of cultural groups, and fictionalists who see such efforts as just creative and fictional extrapolation. Developing the fictionalist position, I suggest it overstates the case against realism: there is plenty of room for realist positions that produce well-grounded empirical studies of cultural groups. Nonetheless, (...) I stress the importance of one element of the fictionalist critique: that the choice of ontology can lead to downstream harm. Developing an extended case study around the work of the anthropologist Julian Steward, I show how ontological decision making is an important element of contemporary scientific and policymaking work. I conclude by arguing that greater attention should be paid both to the processes by which ontologies are adopted and the potential consequences that may result. (shrink)
