I will divide my discussion into two. In the first part I will discuss Godin and Gingras's delicious claim (this volume) that the experimenter's regress is anticipated by Sextus Empiricus's formulation of scepticism. In the second part, I will try to deal with Godin and Gingras's 'critical argument', that the experimenter's regress would be redundant if we were less concerned with 'frightening philosophers'.
This paper investigates what the source of time asymmetry is in thermodynamics, and comments on the question whether a time-symmetric formulation of the Second Law is possible.
Biological research on aggression is increasingly consulted for possible answers to the social problems of crime and violence. This paper reviews some contrasting approaches to the biological understanding of behavior-behavioral genetic, social-environmental, physiological, developmental-as a prelude to arguing that approaches to aggression are beset by vagueness and imprecision in their definitions and disunity in their measurement strategies. This vagueness and disunity undermines attempts to compare and evaluate the different approaches empirically. Nevertheless, the definitions reveal commitments to particular metaphysical views concerning (...) behavior. Alternative understandings of aggression suggest even different research approaches than those most commonly found in the literature. (shrink)
This paper argues that spacetime visualisability is not a necessary condition for the intelligibility of theories in physics. Visualisation can be an important tool for rendering a theory intelligible, but it is by no means a sine qua non. The paper examines the historical transition from classical to quantum physics, and analyses the role of visualisability (Anschaulichkeit) and its relation to intelligibility. On the basis of this historical analysis, an alternative conception of the intelligibility of scientific theories is proposed, based (...) on Heisenberg's reinterpretation of the notion of Anschaulichkeit.

Scientists are always doing experiments or making observations that disappoint them. Most negative experiments are consigned to the file drawer. But in physics, lead is regularly transmuted into gold by treating a negative result as an upper limit-an observation of the maximum strength of the phenomenon under investigation. The logic and sociology of upper limits and the logic and sociology of positive results are different. I explore the difference through a case study in the physical sciences. In the conclusion I (...) ask why social sciences only rarely translate their negative findings into successes. (shrink)
In this paper it is shown that, in spite of their intuitive starting points, Kuipers' accounts lead to counterintuitive consequences. The counterintuitive results of Kuipers' account of H-D confirmation stem from the fact that Kuipers explicates a concept of partial (as opposed to full) confirmation. It is shown that Schurz-Weingartner's relevant-element approach as well as Gemes' content-part approach provide an account of full confirmation that does not lead to these counterintuitive results. One of the unwelcome results of Kuipers' account of (...) nomic truthlikeness is the consequence that a theory Y, in order to be more truthlike than a theory X (where Y and X are incompatible), must imply the entire nomic truth. It is shown how the relevant-element approach to truthlikeness avoids this result. (shrink)
Trata-se de uma reflexão sobre as ameaças aos direitos humanos, sobretudo à dignidade e à liberdade, e à essência humana geradas pelo avanço da biotecnologia. O foco de alerta e resgate da noção de cuidado de si perpassa a perspectiva de futuro de M. Foucault e usa como complemento e desfecho a noção de responsabilidade de H. Jonas para a manutenção da vida e para a realização do sentido do humano e das novas gerações – papel ético por excelência.

An intricate, long, and occasionally heated debate surrounds Boltzmann’s H-theorem (1872) and his combinatorial interpretation of the second law (1877). After almost a century of devoted and knowledgeable scholarship, there is still no agreement as to whether Boltzmann changed his view of the second law after Loschmidt’s 1876 reversibility argument or whether he had already been holding a probabilistic conception for some years at that point. In this paper, I argue that there was no abrupt statistical turn. In the first (...) part, I discuss the development of Boltzmann’s research from 1868 to the formulation of the H-theorem. This reconstruction shows that Boltzmann adopted a pluralistic strategy based on the interplay between a kinetic and a combinatorial approach. Moreover, it shows that the extensive use of asymptotic conditions allowed Boltzmann to bracket the problem of exceptions. In the second part I suggest that both Loschmidt’s challenge and Boltzmann’s response to it did not concern the H-theorem. The close relation between the theorem and the reversibility argument is a consequence of later investigations on the subject. (shrink)
New Waves in Philosophy, a book collection that stands out for giving a snapshot of research in all areas of philosophy is a successful editorial project addressed by Vincent F.

Until recently, little was known of H.L.A. Hart’s private life. That has now changed with the publication of Nicola Lacey’s A Life of H.L.A. Hart: The Nightmare and the Noble Dream. Drawing on Hart’s notebooks and correspondence, Lacey paints an illuminating portrait of Hart, which reveals that despite his public success he struggled with internal perplexities, including his sexual orientation, Jewish identity, intellectual insecurity, and unconventional marriage. Yet, as critics have noted, the connection between these revelations and the development of (...) Hart’s ideas is unclear. Moreover, one cannot help but wonder whether by focusing on these aspects of Hart’s personal life, Lacey has missed an opportunity to explore certain basic questions about his jurisprudence and its link to wider intellectual currents. For example, linguistics, psychology, and the philosophy of language and mind are much different today than they were in the 1940s and 1950s, yet Lacey does not discuss how such familiar events as the overthrow of logical positivism, the demise of behaviorism, the rise of generative linguistics, or the broader cognitive revolution of which they were a part actually impacted Hart or should influence our understanding of his legacy. Surprisingly, none of these developments are taken up in this book, leading one to ponder the significance of their absence. (shrink)
This article is an investigation of parallel themes in Heinrich Hertz's philosophy science and Kant's theory of schemata, symbols and regulative ideas. It is argued that Hertz's "pictures" bears close similarities to Kantian "schemata", that is, they are rules linking concepts to intuitions and provide them with their meaning. Kant's distinction between symbols and schemata is discussed and related to Hertz's three pictures of mechanics. It is argued that Hertz considered his own picture of mechanics (the "hidden mass" picture) as (...) symbolic in a different way than the force and energy pictures. In the final part of the article it is described how Harald Høffding soon after the publication of Hertz's Principles of Mechanics developed a general theory of analogical reasoning, relying on the ideas of Hertz and Kant.

Abstract It is sometimes thought that Absolute Idealism was undermined by its inability to deal with science. Through a critical discussion of F. H. Bradley's philosophy of science, this idea is challenged. His views on science are divided into a positive and a negative part, and it is argued that, although he found the scientific world view to be essentially false, he was nonetheless able to develop a sympathetic and intelligent philosophy of science. This was basically pragmatic and instrumental in (...) tone, and gave to science a large measure of autonomy from philosophy. His doctrine is connected with certain contemporary ideas in the philosophy of science. (shrink)
Renaud Barbaras wants to show that only the concept of life can help us understand how the subject may be a condition as well as a part of the world. The failures of the former phenomenological theories on this point is due to “the ontology of death” they assume, which leads to separate the conscience and the body. It is thus required to realise an epochè of death so as to think the unity of the subject. Ultimately, Renaud Barbaras is (...) led to define life from desire. (shrink)
We show that the ordered field of real numbers with restricted $\mathbb{R}_{\mathscr{H}}$-definable analytic functions admits quantifier elimination if we add a function symbol $^{-1}$ for the function $x\mapsto \frac{1}{x}$ (with $0^{-1}=0$ by convention), where $\mathbb{R}_{\mathscr{H}}$ is the real field augmented by the functions in the family $\mathscr{H}$ of restricted parts (real and imaginary) of holomorphic functions which satisfies certain conditions. Further, with another condition on $\mathscr{H}$ we show that the structure ($\mathbb{R}_{\mathscr{H}}$, constants) is strongly model complete.
Irene Oh affirms that religious freedom, faith, and reason, as David Hollenbach suggests, are subject matters that offer promising platforms for interreligious dialogue between Christians and Muslims. The need for cross-cultural understanding is imperative especially given the current political climate, in which world leaders can easily exacerbate existing tensions through the misapplication of such terms. Sohail H. Hashmi addresses the need to discuss women's rights as part of a larger discussion on human rights in Islam. Oh concurs and notes that (...) Sayyid Qutb's remarks on women in the United States serve as a starting point for clarifying women's agency in Islam. (shrink)
Measure H is confusing to many people, because the scientific issues involved are complex, and few have the necessary scientific background to analyze them themselves. When those of us of more advanced years were growing up, the university scientific community for the most part was independent and objective, today even the best universities are dependent upon multinational corporations for their funding. Many scientists even have to go out and fund-raise for major portions of their own salaries. Nowhere is the situation (...) worse in this regard than in the field of biotechnology. And no modern day Jesus has yet driven the money-changers from the temple of science. Where else can we look for guidance? (shrink)
Kurt Gödel (1906 - 1978) was the most outstanding logician of the twentieth century, famous for his hallmark works on the completeness of logic, the incompleteness of number theory, and the consistency of the axiom of choice and the continuum hypothesis. He is also noted for his work on constructivity, the decision problem, and the foundations of computability theory, as well as for the strong individuality of his writings on the philosophy of mathematics. He is less well known for his (...) discovery of unusual cosmological models for Einstein's equations, in theory permitting time travel into the past. The Collected Works is a landmark resource that draws together a lifetime of creative thought and accomplishment. The first two volumes were devoted to Gödel's publications in full (both in original and translation), and the third volume featured a wide selection of unpublished articles and lecture texts found in Gödel's Nachlass. These long-awaited final two volumes contain Gödel's correspondence of logical, philosophical, and scientific interest. Volume IV covers A to G, with H to Z in volume V; in addition, Volume V contains a full inventory of Gödel's Nachlass. L All volumes include introductory notes that provide extensive explanatory and historical commentary on each body of work, English translations of material originally written in German (some transcribed from the Gabelsberger shorthand), and a complete bibliography of all works cited. Kurt Gödel: Collected Works is designed to be useful and accessible to as wide an audience as possible without sacrificing scientific or historical accuracy. The only comprehensive edition of Gödel's work available, it will be an essential part of the working library of professionals and students in logic, mathematics, philosophy, history of science, and computer science and all others who wish to be acquainted with one of the great minds of the twentieth century.

In this paper it is shown that Heyting and Co-Heyting mereological systems provide a convenient conceptual framework for spatial reasoning, in which spatial concepts such as connectedness, interior parts, (exterior) contact, and boundary can be defined in a natural and intuitively appealing way. This fact refutes the wide-spread contention that mereology cannot deal with the more advanced aspects of spatial reasoning and therefore has to be enhanced by further non-mereological concepts to overcome its congenital limitations. The allegedly unmereological concept of (...) boundary is treated in detail and shown to be essentially affected by mereological considerations. More precisely, the concept of boundary turns out to be realizable in a variety of different mereologically grounded versions. In particular, every part K of a Heyting algebra H gives rise to a well-behaved K-relative boundary operator. (shrink)
The old medieval problem of the temporal relationship between an eternal God and an eternal or timed world remains an issue that animates debates about the nature of God in contemporary philosophy of religion. The Islamic debate pitted the philosophers, in particular Ibn Sīnā [Avicenna], who held that an eternal God produced an eternal world that was merely logically posterior to him, against some theologians, such as al-Ghazālī (Alghazel) who insisted on the scriptural doctrine of creatio ex nihilo and refuted (...) the possibility of an eternal world. The conflict continued with each side ceding some aspects and rejecting others until the Safavid period in which one finds the divisions between philosophy and theology irrevocably breaking down. I shall discuss the positions of three key philosophers of early modern Iran who all defended the doctrine of creatio ex nihilo from a philosophical perspective and came up with some novel approaches to the old problem of the temporal relationship between God and creation. /// O presente artigo parte da constatação de que o velho problema dos pensadores medievais acerca do relacionamento temporal entre um Deus que é eterno e um mundo que ora se entende como eterno ora como localizado no tempo permanece ainda hoje um dos assuntos que animam os debates relativos à natureza de Deus na fdosofia da religião contemporânea. Constata-se, antes de mais, que o debate que se verificou no seio do Islão começou por levantar os filósofos, particularmente Ibn Sīnā [Avicenna], o qual defendia que um Deus eterno produziu um mundo eterno que apenas do ponto de vista lógico lhe era posterior, contra os teólogos, tais como al-Ghazātī [Alghazel], o qual insistia na doutrina baseada na Escritura da creatio ex nihilo e refutava a possibilidade de um mundo eterno. O conflito continuou com cada uma das partes cedendo alguns aspectos e rejeitando outros até à emergência do período dos Safavidas durante o qual se verifica o rompimento das divisões entre Filosofia e Teologia. Assim, o autor do artigo propõe-se analisar as posições de três filósofos fundamentais do início da era moderna no Irão, pensadores esses que defendiam a doutrína da creatio ex nihilo numa perspectiva filosófica e, ao mesmo tempo, foram capazes de avançar com algumas abordagens novas ao velho problema da relação temporal entre Deus e a criação.

El Estado es un concepto clave en la filosofía jurídico-política de José Ortega y Gasset (Madrid, 1883-1955). Sin embargo, resulta sorprendente que, pese a la importancia que para este autor tenía dicha noción, no haya sido estudiada con la misma profundidad e interés que otras vertientes de su pensamiento. A este respecto, basta repasar las monografías y los artículos publicados hasta la fecha sobre la figura y la obra de Ortega para constatar que, en términos cuantitativos, las investigaciones dedicadas a (...) la idea orteguiana del Estado han sido apenas testimoniales, y desde luego no son tan significativas como las que se han podido dedicar a otros temas o tópicos más conocidos de su pensamiento. Así pues, el presente libro pretende abordar el estudio de la realidad problemática del Estado en su triple dimensión histórica, sociológica y política. De acuerdo con tal propósito, esta monografía se divide en tres partes: en la primera de ellas, se estudian las instituciones políticas de Roma entendidas por Ortega como precedentes ineludibles para la formación histórica del Estado. La segunda parte de la obra versa sobre el Estado concebido como culminación de lo social, es decir, como órgano diferenciado para el ejercicio del poder público, lo cual conduce indefectiblemente hasta la Teoría de los usos sociales. Por último, la tercera parte se centra en el concepto orteguiano de Estado como forma de organización política, explica la relación que mantienen el Estado y nación en su obra, y expone las líneas principales del programa político pensado por Ortega para modernizar, regenerar y europeizar a España.

Formal semantics is an approach to SEMANTICS1, the study of meaning, with roots in logic, the philosophy of language, and linguistics, and since the 1980’s a core area of linguistic theory. Characteristics of formal semantics to be treated in this article include the following: Formal semanticists treat meaning as mind-independent (though abstract), contrasting with the view of meanings as concepts “in the head” (see I-LANGUAGE AND E-LANGUAGE and MEANING EXTERNALISM AND INTERNALISM); formal semanticists distinguish semantics from knowledge of semantics (Lewis (...) 1975, Cresswell 1978), which has consequences for the notion of semantic COMPETENCE. A central part of the meaning of a sentence on this approach is its TRUTH CONDITIONS, and most although not all formal semantics is model-theoretic, relating linguistic expressions to model-theoretically constructed semantic values cast in terms of truth, REFERENCE, and possible worlds. This sets formal semantics apart from approaches which view semantics as relating a sentence just to a representation on another linguistic “level” (LOGICAL FORM) or a representation in an innate LANGUAGE OF THOUGHT. The formal semanticist could accept such representations as an aspect of semantics but would insist on asking what the model-theoretic semantic interpretation of the given representationlanguage is (Lewis 1970). Formal semantics is centrally concerned with COMPOSITIONALITY at the SYNTAX-SEMANTICS INTERFACE, how the meanings of larger constituents are built up from the meanings of their parts on the basis of their syntactic structure, and with the relation between compositional SENTENCE MEANING and meaning in discourse.

I consider two logically independent definitions of (mereological) sum identity when x is a sum of the ys and w is a sum of the zs. Def 1 x=y: every part of every y shares a part with some z, and every part of every z shares a part with some y. Def 2 x = y: all the ys are zs, and all the zs are ys. Neither allows a sum to change its parts. Peter van Inwagen tells a (...) story about a brick house that persists through the loss of a brick (The Journal of Philosophy 2006: 614–30). His claim that this story illustrates the persistence of a sum through the loss of a part conflicts with other unassailable assumptions. An understanding of sum identity that does not allow a sum to change its parts if helpful in thinking about material composition. (shrink)
In Memories and Portraits: Explorations in American Thought, H. G. Callaway embeds his distinctive contextualism and philosophical pluralism within strands of history and autobiography, spanning three continents. Starting in Philadelphia, and reflecting on the meaning of home in American thought, he offers a philosophically inspired narrative of travel and explorations, in Europe and Africa, illuminating central elements of American thought—partly out of diverse foreign and domestic reactions and fascinating cultural contrasts. -/- This book is of interest for the contemporary interplay (...) of analytic philosophy with American pragmatism and for those focused on the interaction of European and Anglo-American thought and society. In this book, the formalism of analytic philosophy encounters a logically articulate version of the contextualism implicit in the pragmatist tradition; and a deep and abiding interest in natural science is augmented by a more literary account of the social and cultural contexts of inquiry—encountered in many years of travel and life abroad. The final chapter, employing a methodological naturalism, brings the perspectives and lessons, from near and far, back home for renewed reflection. (shrink)
The paper argues that very different part-whole relations hold between different kinds of entities. While these relations share most of their formal properties, they need not share all of them. Nor need other mereological principles be true of all kinds of part–whole pairs. In particular, it is argued that the principle of unrestricted composition, that any two or more entities have a mereological sum, while true of sets and propositions, is false of things and events.
This paper is the first in a two-part series in which we discuss several notions of completeness for systems of mathematical axioms, with special focus on their interrelations and historical origins in the development of the axiomatic method. We argue that, both from historical and logical points of view, higher-order logic is an appropriate framework for considering such notions, and we consider some open questions in higher-order axiomatics. In addition, we indicate how one can fruitfully extend the usual set-theoretic semantics (...) so as to shed new light on the relevant strengths and limits of higher-order logic. (shrink)
Rudolf Carnap delivered the hitherto unpublished lecture ‘Theoretical Concepts in Science’ at the meeting of the American Philosophical Association, Pacific Division, at Santa Barbara, California, on 29 December 1959. It was part of a symposium on ‘Carnap’s views on Theoretical Concepts in Science’. In the bibliography that appears in the end of the volume, ‘The Philosophy of Rudolf Carnap’, edited by Paul Arthur Schilpp, a revised version of this address appears to be among Carnap’s forthcoming papers. But although Carnap (...) started to revise it, he never finished the revision,1 and never published the unrevised transcript. Perhaps this is because variants of the approach to theoretical concepts presented for the first time in the Santa Barbara lecture have appeared in other papers of his (cf. the editorial footnotes in Carnap’s lecture). Still, I think, the Santa Barbara address is a little philosophical gem that needs to see the light of day. The document that follows is the unrevised transcript of Carnap’s lecture.2 Its style, then, is that of an oral presentation. I decided to leave it as it is, making only very minor stylistic changes—which, except those related to punctuation, are indicated by curly brackets.3 I think that reading this lecture is a rewarding experience, punctuated as the lecture is with odd remarks and autobiographical points.
