In redefining logic, philosophers need to go back to the Aristotelian roots of the subject, to expand the boundaries of the subject to include informal logic and to give up false oppositions between informal and formal logic.

Can thought arise out of matter? Can self, soul, consciousness, “I” arise out of mere matter? If it cannot, then how can you or I be here? I Am a Strange Loop argues that the key to understanding selves and consciousness is the “strange loop”—a special kind of abstract feedback loop inhabiting our brains. The most central and complex symbol in your brain is the one called “I.” The “I” is the nexus in our brain, one of many symbols seeming (...) to have free will and to have gained the paradoxical ability to push particles around, rather than the reverse. How can a mysterious abstraction be real—or is our “I” merely a convenient fiction? Does an “I” exert genuine power over the particles in our brain, or is it helplessly pushed around by the laws of physics? These are the mysteries tackled in I Am a Strange Loop, Douglas Hofstadter's first book-length journey into philosophy since Gödel, Escher, Bach. Compulsively readable and endlessly thought-provoking, this is a moving and profound inquiry into the nature of mind. (shrink)

Several diagrams and tables from review articles during the Ox-Phos Controversy serve as an occasion to assess the nature of competition in models of theory choice in science. Many models follow "Super-Bowl" principles of polar, either-or, winner-take-all competition. A significant alternative highlighted by this episode, however, is the differentiation of domains. Incommensurability and the partial divergence of overlapping domains serve both as signals and context for shifting frameworks of competition. Appropriate strategies may thus help researchers diagnose the status of competition (...) and shape their research accordingly. (shrink)

The aim of this paper is to make it clear how and why begging the question should be seen as a pragmatic fallacy which can only be properly evaluated in a context of dialogue. Included in the paper is a review of the contemporary literature on begging the question that shows the gradual emergence over the past twenty years or so of the dialectical conception of this fallacy. A second aim of the paper is to investigate a number of general (...) problems raised by the pragmatic framework. (shrink)

Analysis and case studies show that including different orientations toward the natural world makes for more effective scientific practice and science education.

In this paper, I try to make a bundle theory of objects consistentwith a temporal parts theory of object persistence. To that end,I propose that such bundles are made up of tropes includingthe co-instantiation relation.

I highlight a category of experiment-what I am calling 'demonstrations'-that differs in justificatory mode and argumentative role from the more familiar 'crucial tests'. 'Tests' are constructed such that alternative results are equally and symmetrically informative; they help discriminate between alternative solutions within a problem-field, where questions are shared. 'Demonstrations' are notably asymmetrical (for example, "failures" are often not telling), yet they are effective, if not "crucial," in interparadigm dispute, to legitimate questions themselves. The Ox-Phos Controversy in bioenergetics serves as an (...) integral case study. (shrink)

This article considers what can be learned regarding the ethical acceptability of intrusive interventions intended to halt the spread of infectious disease (‘Infection Control’ measures) from existing ethical discussion of intrusive interventions used to prevent criminal conduct (‘Crime Control’ measures). The main body of the article identifies and briefly describes six objections that have been advanced against Crime Control, and considers how these might apply to Infection Control. The final section then draws out some more general lessons from the foregoing (...) analysis for the ethical acceptability of different kinds of Infection Control. (shrink)

In his "A Neglected Argument for the Reality of Goc" (1908), Charles Peirce argued for two dimensions of belief in God's reality. On the one side, he maintained that this belief would be useful for guiding the conduct of life; on the other side, he maintained that the belief could function as the first stage in a scientific inquiry. My suggestion in this paper is that we examine the last of Peirce's 1903 lectures on pragmatism at Harvard to see how (...) the possibility of this dual function arises out of his late theory of cognition in which the functional certainty of perception is brought to close quarters with the provisionality of hypotheses. The upshot is that for Peirce a healthful religious belief should internally "marry" science and religion —theory and practice — by allowing provisional and vague conceptions of God to carry on the work of guiding conduct. /// No texto "A Neglected Argument for the Reality of God" (1908), Charles Peirce defende que há duas dimensões de crença na realidade de Deus. Afirma, por um lado, que esta crença poderia ser útil para orientar o comportamento (conduct of life); por outro, que ela poderia ser como que o primeiro escalão numa investigação científica. A minha sugestão neste artigo é que, examinámos as últimas conferências de Peirce de 1903 sobre o pragmatismo em Harvard para ver como a possibilidade desta dupla função surge da sua última teoria de conhecimento (cognition) em que a certeza funcional de percepção é usada para aproximar o aspecto provisório das hipóteses. A consequência disso é que para Peirce uma saudável crença religiosa deve "juntar" internamente ciência e religião - teoria e prática - permitindo as concepções provisórias e vagas de Deus para continuar a tarefa de orientar o comportamento. /// Dans ce texte "Un argument négligé pour la réalité de Dieu" (1908), Charles Peirce soutient qu'il y a deux dimensions de croyance en la réalité de Dieu. Il afflrme, d'un côté, que cette croyance pourrait être utile pour orienter le comportement (conduct of life) et, par ailleurs, qu'elle pourrait être pour ainsi dire le premier niveau dans une recherche scientifique. Ma suggestion dans le présent article est que nous examinions les dernières conférences de Peirce en 1903 sur le pragmatisme à Harvard pour voir comment Ia possibilite de cette double fonction surgit de sa dernière théorie de la connaissance dans laquelle la certitude fonctionnelle de perception est utilisée pour aborder l'aspect provisoire des hypothèses. La conséquence en est que pour Peirce une saine croyance religieuse doit "unir" intrinsèquement science et religion - théorie et pratique - en permettant les conceptions provisoires et vagues de Dieu.

We shall be in a position to hear the voice of the Good Shepherd only when we have stopped using the Christian religion to shield us from the realities of our lostness and our night.

Understanding is not of the same kind in all contexts. Children learn the kind of understanding that is appropriate in particular contexts largely through a process of enculturation. This study examines some aspects of 10-year-old children's conceptions of understanding. There was evidence that they had admissible conceptions of understanding in general but may be unable to distinguish unaided between the kinds of understanding that are relevant in different disciplines. An explicit attention to enculturation in lesson plans may be of benefit (...) to such children. (shrink)

In contrast to classical natural law theory and traditional individualist liberalism, James Luther Adams develops a version of natural law doctrine grounded in liberal religion. In its ontological dimension, his natural law doctrine is derived from a communal understanding of the character of reality. In its institutional dimension, his natural law doctrine promotes a kind of democracy in which freedom of association is central. From this perspective, law is a practice intended to empower persons through their several associations in the (...) constant formation and transformation of community under the direction of divine power.

This article assesses what standards of safety and certainty of diagnosis need to be met in the determination of brain death. Recent medical, legal, and philosophical developments on brain death are summarized. It is argued that epistemologically adequate standards require the finding of whole-brain death rather than destruction of the cortex. Because of the possibility of positive error in misdiagnosing death, a tutioristic approach of being on the safe side is advocated. Given uncertainties in diagnosis of so-called vegetative states like (...) the apallic syndrome, anything less than whole-brain death, especially given the present state of diagnostic capability, should not qualify as an argument for removing therapy specifically on grounds that the patient is dead.

This paper examines the impact of the introduction of Western (European) technical civilization on regional cultures in Nigeria, using Igboland in South-EasternNigeria as a test case. It begins with a discussion of some general features of Western technical civilization whose evolution has been profoundly influenced by technological advances in Europe and her cultural colonies in North America and elsewhere. Consequences of the contact between Western technical civilization and traditional Igbo culture are also examined. The paper concludes by discussing the challenging (...) problem of Africa’s contribution to technical civilization. (shrink)

The existence of either a maximum or a minimum for a uniformly continuous mapping f of a compact interval into ${\mathbb{R}}$ is established constructively under the hypotheses that f′ is sequentially continuous and f has at most one critical point.

Two classically equivalent, but constructively inequivalent, strict convexity properties of a preference relation are discussed, and conditions given under which the stronger notion is a consequence of the weaker. The last part of the paper introduces uniformly rotund preferences, and shows that uniform rotundity implies strict convexity. The paper is written from a strictly constructive point of view, in which all proofs embody algorithms. MSC: 03F60, 90A06.

Do classical, contemplative philosophies have anything to teach which is relevant to life here and now? In the case of Plotinus, yes. While Platonic metaphysics is most often summarized as dualistic, where one sensible world stands apart from and in tension with an intelligible world, in the case of Plotinus this interpretation is incorrect. He does distinguish between sensibles and sense-experience, on one hand, and intelligibles and intelligible experience, on the other; but the two belong together intimately: both are located (...) in the same space, and the sensible is related to the intelligible as a shadow to its object or a reflection to what it reflects. Plotinus’ world is one. Given this picture, one rightly wonders at the status of the Plotinian exhortation for the soul to flee "alone to the Alone." Does not the journey of the soul to its source require a passing beyond of this world to some other? No, Plotinus exhortation should be understood as a reorientation, a reordering within the world here and now, not a rejection of one reality in favor of some other. This can be likened to Aesop’s fable, "The Dog and the Bone," where the dog had the choice between one real and one illusory bone, not two separate bones. Similarly, Plotinus’ world, though it can be perceived dualistically, is ontologically one; hence his metaphysics, far from otherworldly, offers a means of understanding life as it is to be lived here and now.

Controlled human infection (CHI) studies involve the deliberate exposure of healthy research participants to infectious agents to study early disease processes and evaluate interventions under controlled conditions with high efficiency. Although CHI studies expose participants to the risk of infection, they are designed to offer investigators unique advantages for studying the pathogenesis of infectious diseases and testing potential vaccines or treatments in humans. One of the central challenges facing investigators involves the fair selection of research subjects to participate in CHI (...) studies. While there is widespread agreement that investigators have a duty to select research participants fairly, this principle also yields conflicting ethical imperatives, for example requiring investigators to both exclude potential participants with co‐morbidities since they face increased risks, but also to include them in order to ensure generalizability. In this paper we defend an account of fair subject selection that is tailored to the context of CHI studies. We identify the considerations of fairness that bear directly on selecting participants for CHI studies and provide investigators and members of IRBs and RECs with a principled way to navigate the conflicting imperatives to which these considerations give rise.
