This paper offers an overview of "the species problem", arguing for a view of species as homeostatic property cluster kinds, positioning the resulting form of realism about species as an alternative to the claim that species are individuals and pluralistic views of species. It draws on taxonomic practice in the neurosciences, especially of neural crest cells and retinal ganglion cells, to motivate both the rejection of the species-as-individuals thesis and species pluralism.

Are interpersonal comparisons of desire possible? Can we give an account of how facts about desires are grounded, that underpins such comparisons? This paper supposes the answer to the first question is yes, and provides an account of the nature of desire that explains how this is so. The account is a modification of the interpretationist metaphysics of representation that the author has recently been developing. The modification is to allow phenomenological affective valence into the “base facts” on which correct (...) interpretation is grounded. To use this extra resource within that theory to vindicate interpersonal comparisons, we will need to appeal rational connections between level of valence and level of desire, which this paper sets out and examines.

The impressive variation amongst biological individuals generates many complexities in addressing the simple-sounding question what is a biological individual? A distinction between evolutionary and physiological individuals is useful in thinking about biological individuals, as is attention to the kinds of groups, such as superorganisms and species, that have sometimes been thought of as biological individuals. More fully understanding the conceptual space that biological individuals occupy also involves considering a range of other concepts, such as life, reproduction, and agency. There has (...) been a focus in some recent discussions by both philosophers and biologists on how evolutionary individuals are created and regulated, as well as continuing work on the evolution of individuality.

This paper explores the relationship between eugenics, disability, and dehumanization, with a focus on forms of eugenics beyond Nazi eugenics.

My aim is to propose affectivity as a criterion for personal identity. My proposal is to be taken in its weak version: affectivity as _only one_ of the criteria for personal identity. I start by arguing for affectivity being a better candidate as a criterion for personal identity than thinking. Next, I focus on synchronic vs. diachronic and on ontic vs. epistemic distinctions (my proposal will concern diachronic ontic personal identity) and consider the realm of affectivity in its temporal dimension. (...) In my argument, I rely on the genuineness of affectivity and I exploit chiefly long- or everlasting feelings (or emotions) and those which involve the feeling subject more rather than less. I conclude by stating that genuine long-lasting feelings (or emotions) are constitutive of diachronic ontic personal identity. (shrink)

Drawing on a passage from Ramsey's Truth and Probability, we formulate a simple, plausible constraint on evaluating the accuracy of credences: the Calibration Test. We show that any additive, continuous accuracy measure that passes the Calibration Test will be strictly proper. Strictly proper accuracy measures are known to support the touchstone results of accuracy-first epistemology, for example vindications of probabilism and conditionalization. We show that our use of Calibration is an improvement on previous such appeals by showing how it answers (...) or sidesteps problems that have been raised for previous work in this area. (shrink)

The paper offers an analysis of Protagoras’ fr. DK 80 B 1 and rejects the traditional reading of Protagoras as relativist. By considering the ipsissima verba that Protagoras makes use of in his passage, it is argued that alternative interpretations are possible, of which epistemological reism and psychological individualism are proposed. On a more general level, it is discussed to what extent Protagoras’ fragment contains descriptive rather than normative claim.

Kenneth Burke, arguably the most important American literary theorist of the twentieth century, helped define the theoretical terrain for contemporary literary and cultural studies. His perspectives were literary and linguistic, but his influences ranged across history, philosophy, and the social sciences. In this important and original study Robert Wess traces the trajectory of Burke's long career and situates his work in relation to postmodernity. His study is both an examination of contemporary theories of rhetoric, ideology, and the subject, and (...) an explanation of why Burke failed to complete his Motives trilogy. Burke's own critique of the 'isolated unique individual' led him to question the possibility of unique individuation, a strategy which anticipated important elements of postmodern concepts of subjectivity. Robert Wess's study is both a timely and judicious exposition of Burke's massive oeuvre, and a crucial intervention in current debates on rhetoric and human agency. (shrink)

Rumelhart and McClelland's chapter about learning the past tense created a degree of controversy extraordinary even in the adversarial culture of modern science. It also stimulated a vast amount of research that advanced the understanding of the past tense, inflectional morphology in English and other languages, the nature of linguistic representations, relations between language and other phenomena such as reading and object recognition, the properties of artificial neural networks, and other topics. We examine the impact of the Rumelhart and McClelland (...) model with the benefit of 25 years of hindsight. It is not clear who “won” the debate. It is clear, however, that the core ideas that the model instantiated have been assimilated into many areas in the study of language, changing the focus of research from abstract characterizations of linguistic competence to an emphasis on the role of the statistical structure of language in acquisition and processing.

Inflectional morphology has been taken as a paradigmatic example of rule-governed grammatical knowledge (Pinker, 1999). The plausibility of this claim may be related to the fact that it is mainly based on studies of English, which has a very simple inflectional system. We examined the representation of inflectional morphology in Serbian, which encodes number, gender, and case for nouns. Linguists standardly characterize this system as a complex set of rules, with disagreements about their exact form. We present analyses of a (...) large corpus of nouns which showed that, as in English, Serbian inflectional morphology is quasiregular: It exhibits numerous partial regularities creating neighborhoods that vary in size and consistency. We then asked whether a simple connectionist network could encode this statistical information in a manner that also supported generalization. A network trained on 3,244 Serbian nouns learned to produce correctly inflected phonological forms from a specification of a word's lemma, gender, number, and case, and generalized to untrained cases. The model's performance was sensitive to variables that also influence human performance, including surface and lemma frequency. It was also influenced by inflectional neighborhood size, a novel measure of the consistency of meaning to form mapping. A word-naming experiment with native Serbian speakers showed that this measure also affects human performance. The results suggest that, as in English, generating correctly inflected forms involves satisfying a small number of simultaneous probabilistic constraints relating form and meaning. Thus, common computational mechanisms may govern the representation and use of inflectional information across typologically diverse languages. (shrink)

If the world itself is metaphysically indeterminate in a specified respect, what follows? In this paper, we develop a theory of metaphysical indeterminacy answering this question.

In the good old days, when general philosophy of science ruled the Earth, a simple division was often invoked to talk about philosophical issues specific to particular kinds of science: that between the natural sciences and the social sciences. Over the last 20 years, philosophical studies shaped around this dichotomy have given way to those organized by more fine-grained categories, corresponding to specific disciplines, as the literatures on the philosophy of physics, biology, economics and psychology--to take the most prominent four (...) examples--have blossomed. In general terms, work in each of these areas has become increasingly enmeshed with that in the corresponding science itself, increasingly naturalistic (in at least one sense of that term), and in my view, increasingly interesting.

Contribución de eruditos autores sobre aspectos trascendentales de la teoría pura del derecho. Esta obra debe verse como una expresión de esa renovada ocupación con los problemas de la doctrina de Kelsen.

Die Meisterwerke der Moralistik haben Millionen von Menschen als philosophische Lebensbegleiter gedient. Doch worum geht es in der Moralistik eigentlich? 0Die Moralistik befasst sich mit der Natur des Menschen und mit Möglichkeiten kluger, individueller Selbstbehauptung. Sie führt die antiken Ansätze einer philosophischen Klugheitslehre fort und besetzt damit einen in der neuzeitlichen Ethik vernachlässigten Teil der praktischen Philosophie. Ihre Meisterwerke vermitteln uns Menschenkenntnis und soziale Orientierung und stehen uns auf dem Weg eines gelingenden Lebens beratend zur Seite. In ihnen liegt der (...) Ursprung der modernen Philosophie der Lebenskunst. Das Buch stellt sowohl die Entwicklung der Moralistik als auch ihr philosophisches Anliegen anschaulich und gut lesbar dar. (shrink)

We distinguish between literal and metaphorical applications of Bayesian models. When intended literally, an isomorphism exists between the elements of representation assumed by the rational analysis and the mechanism that implements the computation. Thus, observation of the implementation can externally validate assumptions underlying the rational analysis. In other applications, no such isomorphism exists, so it is not clear how the assumptions that allow a Bayesian model to fit data can be independently validated.

Se resume en esta obra el vasto y complejo sistema teórico-jurídico de Hans Kelsen, el jurista más grande de nuestro siglo. La doctrina de Kelsen y en particular su Teoría Pura del Derecho han conocido muchas vicisitudes y ataques debidos más a prejuicios políticos y racistas que a una verdadera confrontación con sus tesis. El autor enfatiza en el hecho de que la doctrina jurídica de Kelsen no es una teoría terminada y archivada sino en permanente desarrollo, una teoría a (...) cuya ulterior construcción están convocados todos los juristas.
