We offer a particularist defense of conspiratorial thinking. We explore the possibility that the presence of a certain kind of evidence—what we call "fortuitous data"—lends rational credence to conspiratorial thinking. In developing our argument, we introduce conspiracy theories and motivate our particularist approach (§1). We then introduce and define fortuitous data (§2). Lastly, we locate an instance of fortuitous data in one real world conspiracy, the Watergate scandal (§3).

This study provides a unified framework within which to view the development of pre-Socratic thought. It points out three aspects of Xenophanes' scepticism, and shows how Heraclitus responded to each. Key issues concerning psyche and logos are summarized and an attempt is made to settle certain long-standing debates concerning them.

Over a period of 19 months in 2006 and 2007, Mattel recalled approximately 14 million toys. The company was subjected to numerous lawsuits and regulatory actions and suffered severe damage to its reputation. Two issues were involved: excessive levels of lead in numerous toy surface paints and small detachable magnets in some toys, which could be swallowed. An examination of the facts shows that two different ethical situations were involved—one concerning product design and the other concerning manufacturing practices of Mattel's (...) Chinese contractors and subcontractors. The ethical obligations of the company and individuals within the company in the two situations were quite different, and illustrate problems faced by companies in managing their global supply chains.

In fact, we can also ensure that a range of equivalence relations modulo various non-stationary ideals are strictly between those isomorphism relations.

Vers la fin du XIVe siècle se fait jour une théorie du signe et de la signification qui, par une réélaboration des principaux concepts sémantiques, renouvelle toute l’analyse logique du langage.Partant de Guillaume d’Ockham, dont l’œuvre est ici décisive, cet ouvrage suit le développement d’une logique fondée sur des éléments de sémiologie, à travers différents auteurs du XIVe siècle tels que Gauthier Burley, Jean Buridan, Albert de Saxe, Marsile d’Inghen, Pierre d’Ailly...Une telle « logique du signe » prend place dans (...) toute une mutation du savoir, en ce siècle où la crise profonde du monde médiéval appelle une autre conception des rapports entre l’homme, les choses extérieures et le langage.

Hoop residuation algebras are the {, 1}-subreducts of hoops; they include Hilbert algebras and the {, 1}-reducts of MV-algebras (also known as Wajsberg algebras). The paper investigates the structure and cardinality of finitely generated free algebras in varieties of k-potent hoop residuation algebras. The assumption of k-potency guarantees local finiteness of the varieties considered. It is shown that the free algebra on n generators in any of these varieties can be represented as a union of n subalgebras, each of which (...) is a copy of the {, 1}-reduct of the same finite MV-algebra, i.e., of the same finite product of linearly ordered (simple) algebras. The cardinality of the product can be determined in principle, and an inclusion-exclusion type argument yields the cardinality of the free algebra. The methods are illustrated by applying them to various cases, both known (varieties generated by a finite linearly ordered Hilbert algebra) and new (residuation reducts of MV-algebras and of hoops).

This paper investigates the compatibility of Hegel’s analyses of the mechanization of work in industrial society with Hegel’s notion of freedom as rational self-determination. Work as such is for Hegel a crucial moment on the way to a more complete realization of human freedom, but, as I maintain with Adorno, the technological developments of the last two centuries raise the question of whether the nature of work itself has changed since the industrial revolution. In his Jena lectures, Hegel recognized significant (...) problems that the mechanization of work poses for human freedom that—on my assessment—his later, mature thought does not sufficiently address. One finds, however, a more comprehensive depiction of the same worries that Hegel mentioned in his Jena lectures in Adorno’s critique of the dominant forms of labor in contemporary society and his understanding of technological rationality, which according to Adorno, dominates the contemporary world. I suggest, furthermore, that juxtaposing Hegel’s and Adorno’s thoughts on technology and the mechanization of work reveals Adorno’s philosophy of technology to be an extension, rather than a critique, of the spirit of Hegel’s own philosophical project as immanent critique of the necessary entailments of any given concept.

We study the Borel reducibility of isomorphism relations in the generalized Baire space. In the main result we show for inaccessible κ, that if T is a classifiable theory and is stable with the orthogonal chain property (OCP), then the isomorphism of models of T is Borel reducible to the isomorphism of models of.

Contrastive epistemologists say knowledge displays the ternary relation “S knows p rather than q”. I argue that “S knows p rather than q” is often equivalent to “S knows p rather than not-p” and hence equivalent to “S knows p”. The result is that contrastive knowledge is often binary knowledge disguised.

Le 14e siècle est une période où les débats sur l'infini se multiplient. Les mêmes doctrines se trouvent indifféremment développées dans les oeuvres théologiques, dans les commentaires sur la "Physique" d'Aristote voire dans des traités spécialement dévolus à la question du continu. Cet ouvrage révèle la place de ces doctrines dans la logique, les mathématiques, la philosophie naturelle.

This article studies Isidore of Seville’s reception of the moral theology of Gregory the Great. Examples will be offered from the Expositio in Vetus Testamentum and the second book of the Differentiae; the moral project of the Sententiae will also be explored. The most significant conclusion is that Isidore refuses to reproduce the most relevant innovations of Gregory’s teaching on charity.

The Belmont Report has had an enormous influence on the ethics of biomedical research over the last several decades. It has served as a philosophical foundation for federal regulations governing human subjects research, and its principles are well known to individuals across the research enterprise. Given the outsized influence Belmont has enjoyed as a core document in bioethics, it is worth reminding ourselves of the historical context in which it came to be. In this article, we examine the societal forces (...) that helped bring about the Belmont Report and that shaped its conception of ethical research. In turn, we set the stage for discussions on whether Belmont remains applicable as the research enterprise... (shrink)

La notion medievale de scientia comporte une multiplicite de dimensions: disposition de l'esprit qui accorde un assentiment justifie a des propositions, discours organise qui doit etre analyse du point de vue des criteres semantiques et des modalites argumentatives, encyclopedie des disciplines profanes ou sacrees. Cet ouvrage etudie systematiquement la theorie buridanienne de la science, la diversite de ses sens, l'etagement de ses degres de certitude depuis la connaissance du contingent jusqu'aux formes les plus rigoureuses du savoir demonstratif, ainsi que la (...) diversite de ses rationalismes regionaux. Avec Jean Buridan (ne entre 1295 et 1300, mort en 1361), la science est solidement ancree dans le monde de la nature des hommes, et se deploie en un reseau des savoirs qui surgissent et se developpent dans le cadre du cours naturel du monde, dessinant le champ autonome de la philosophie.

The standard interpretations of Foucault's intellectual biography usually present Sartre as his major adversary. Though it would be difficult to underestimate the importance of Sartre for Foucault's development, this paper argues that Foucault was involved in an even more intense and deeper contest with Freud. Indeed, Freud was Foucault's principal adversary and, throughout his career, Foucault was trying to formulate a counter-project to psychoanalysis. The author attempts to demonstrate this claim by examining Foucault's early psychological writings, Madness and Civilization, his (...) encounter with Kant in The Order of Things and The History of Sexuality. He argues, moreover, that Foucault had articulated a project, namely, 'the dialogue with unreason', which not only could have provided a meeting point for his project and Freud's but can still provide a way of getting beyond the exhausted debate between the advocates of the Enlightenment and the Anti-Enlightenment. Because he could never give up the temptation to valorize transgression, however, Foucault was unable to pursue the dialogue with unreason in a systematic way. Key Words: Foucault • Freud • psychoanalysis • reason. (shrink)

Joel Marks discusses the philosophical aspects of a question recently in the news: is Pluto a planet, or not?

This paper engages in an interpretation and critique of Simondon’s approach to technical objects through his concept of alienation. I begin with his argument for why the fundamental source of alienation is “psycho-physical” and explain his critique of politico-economic analyses of alienation. I then explain his proposal for reducing alienation by rethinking work as “technical activity.” I then argue that while Simondon’s analyses of the internal functionality of technical objects provide important contributions to the philosophy of technology, he also overemphasizes (...) the psycho-physical and in turn underestimates the role of politico-economic factors in the ontogenesis of technical objects and production of alienation. Both the psycho-physical and politico-economic, I claim, must be thought together as necessarily interconnected conditions of the ontogenesis of technical objects. On that basis, it becomes possible to engage in philosophical critique of and education about the inner functionality of contemporary technologies and their accompanying risks. (shrink)

This book offers an introduction to critical thinking for sociologists. Critical thinking involves the evaluation of arguments. Because sociologists tend to use particular forms of argumentation, it is helpful to consider how such arguments might be evaluated. Taking these matters into consideration can improve sociological arguments.

Tout au long de la période médiévale, la logique est un instrument privilégié d'acquisition et d'exposition des autres savoirs. Dans cet article, on se propose d'évaluer la portée de son investissement dans le champ de la philosophie naturelle, à partir d'un exemple: celui d'Albert de Saxe . A travers l'étude de la quantité et du mouvement, on voit se mettre en place une approche originale du corps naturel. All along the Medieval period, logic is an instrument for acquisition and exposition (...) of the other fiels of knowing. In this article is proposed an evaluation of the results of its use in natural philosophy, through an example: that of Albert of Saxony . By studing quantity and mouvement, we can see the emergence of an original approach of the natural body. (shrink)
