Alan Turing is known for both his mathematical creativity and genius and role in cryptography war efforts, and for his homosexuality, for which he was persecuted. Yet there is little work that brings these two parts of his life together. This paper deconstructs and moves beyond the extant stereotypes around perceived associations between gay men and creativity, to consider how Turing’s lived experience as a queer mathematician provides a rich seam of insight into the ways in which his life, relationships, (...) and working environment shaped his work.

In February 1686, Gottfried Wilhelm Leibniz sent a letter to Antoine Arnauld, via their mutual friend Ernst, the Landgrave of Hessen-Rheinfels. This letter contained a short summary of Leibniz's most recent philosophical work, the Discourse on Metaphysics, and asked Arnauld for his reaction to it. Arnauld's response was extremely harsh: he called Leibniz's views shocking and useless and advised him to stop engaging in metaphysical speculations. Yet, Leibniz did not let this discourage him. In the exchange that followed, Leibniz was (...) intent on convincing Arnauld that the views contained in the Discourse are well supported and less radical than Arnauld initially thought. And while he never convinced Arnauld... (shrink)

The author presents and defends three theses: (1) "the first is that it is not profitable for us at present to do moral philosophy; that should be laid aside at any rate until we have an adequate philosophy of psychology." (2) "the second is that the concepts of obligation, And duty... And of what is morally right and wrong, And of the moral sense of 'ought', Ought to be jettisoned if this is psychologically possible...." (3) "the third thesis is that (...) the differences between the well-Known english writers on moral philosophy from sidgwick to the present day are of little importance." (staff). (shrink)

Research that is initiated, designed or funded by sponsor agencies based in countries with relatively high social and economic development, and conducted in countries that are relatively less developed, gives rise to many important ethical challenges. Although clinical trials of HIV vaccines began ten years ago in the US and Europe, an increasing number of trials are now being conducted or planned in other countries, including several that are considered “developing” countries. Safeguarding the rights and welfare of individuals participating as (...) research subjects in developing countries is a priority. In September, 1997, the Joint United Nations Programme on HIV/AIDS embarked on a process of international consultation; its purpose was further to define the important ethical issues and to formulate guidance that might facilitate the ethical design and conduct of HIV vaccine trials in international contexts. This paper summarises the major outcomes of the UNAIDS consultative process. (shrink)

Formal principals are isolated to reveal a structure embedded in a wide range of studies, each of which partitions a domain of individuals into types and categories. It is thought that any reasonable theory of types should include these principles.

Descartes's epistemology, morals, and metaphysics – each offer reason to look on real life as a spectator looks on a theater production. The meditator seeking certainty watches his body move as in a dream and employs an entirely passive faculty of knowledge. In order to act firmly and yet not risk disappointment, the moral subject confines action to the soul, refusing to count bodily activities as actions, and cultivates a desire free from passion. After the Meditations, the metaphysician abandons the (...) thesis that soul and body constitute a human being, consequently limiting human goods to goods of the soul alone and devaluing embodied life in the world.

This book offers an introduction to the Sophists of fifth-century Athens and a new overall interpretation of their thought. Since Plato first animadverted on their activities, the Sophists have commonly been presented as little better than intellectual mountebanks - a picture which Professor Kerferd forcefully challenges here. Interpreting the evidence with care, he shows them to have been part of an exciting and historically crucial intellectual movement. At the centre of their teaching was a form of relativism, most famously expressed (...) by Protagoras as 'Man is the measure of all things', and which they developed in a wide range of views - on knowledge and argument, virtue, government, society, and the gods. On all these subjects the Sophists did far more than simply provoke Plato to thought. Their contributions were substantial and serious; they inaugurated the debate on many central philosophical questions and decisively shifted the focus of philosophical attention from the cosmos to man.

The paper is a critical discussion of scholarship on the "Critique of Pure Reason" published during the past ten years. The emphasis is on Anglo-American authors. I identify and discuss three main trends in the field: a shift from the general discussion of transcendental arguments to the analysis and evaluation of particular proofs in Kant; a renewed interest in the doctrine of transcendental idealism and the distinction between things in themselves and appearances; and the emergence of an entire body of (...) literature on Kant's philosophy of mind, centered around the idea of a "transcendental psychology." The main body of the text is supplemented by extensive bibliographical information provided in the notes. (shrink)

As Husserl already noticed, artworks themselves have a phenomenological character. This means, however, that to experience artworks as phenomena no “epoché” and no “phenomenological reduction” is necessary. The leading question of my essay is whether, and possibly how, this observation can be methodologically generalized for understanding phenomena. I discuss if, and possibly how, a phenomenological reflection on art allows and even demands a general conception of phenomenology that nevertheless does not confuse artworks with phenomena in general. My intention is to (...) show that and how phenomenality can be clarified with reference to its spatial character. Accordingly, works of architecture that are artworks will play a decisive role in my argument. (shrink)

Scientific exploration and thus our knowledge about the outside world is subject to the conditions of our experience.These conditions are condensed here into an interface model which,besides being physical,has an additional interface structure not reducible to physics. We suggest that this structure can dynamically be characterized by separate modes.Their selection and operation presupposes free will and a rudimentary concept of time and space. Based on some analogies with quantum networks it is argued that the 'observed' gets 'dressed'as a consequence of (...) the observing. Interface dynamics and system dynamics supplement each other without over- determination. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Ideas 63.3 (2002) 371-397 [Access article in PDF] How the "New Science" of Cannons Shook up the Aristotelian Cosmos Mary J. Henninger-Voss [Figures]Approximately halfway through the "Second Day" of Galileo's Dialogue Concerning the Two Chief World Systems Galileo's mouthpiece, the mathematician Salviati, scoffs at his Aristotelian colleague Simplicio: "I see that you have hitherto been of that herd who, in order to learn how (...) matters such as this [motion] take place, and in order to acquire a knowledge of natural effects, do not betake themselves to ships or crossbows or cannons, but retire to their studies... to see whether Aristotle has said anything about them."1 Silly, simple Simplicio! He has been searching for natural philosophical wisdom in the books of natural philosophers rather than in the world of docks and arsenals. Indeed this quotation appears near the outset of Day Two wherein Salviati offers cannonshot as proof for the opposing Aristotelian position that the experience of projectiles proves the motionless state of the earth. Obviously, if the earth rotates toward the east, cannonballs shot point-blank to the west ought to travel much further than to the east. And clearly this is not so. Simplicio agrees that the new arguments offered by the cannon are excellent, "and now I see with how many elegant experiments nature graciously wishes to aid us in coming to the recognition of the truth," Simplicio enthusiastically enjoins. "What a shame there were no cannons in Aristotle's time!" exclaims the third interlocutor, Sagredo. "With them he would indeed have battered down ignorance, and spoken without [End Page 371] [Begin Page 373] the least hesitation concerning the universe."2 The irony here is not only that Aristotle might have used cannons in order to explain the workings of the universe but also that Galileo does so in the following pages. His demonstrations with reference to artillery demolish the Aristotelian position, but he has had Simplicio open the door for him by recognizing this most violent of artifices as an elegant experiment provided by nature.3The cannon provides a primary referent for Galileo's new mathematical physics of motion from his very first dialogue to his very last. The early De Motu culminated in a series of questions about the shot of cannons, while the conversation in his final masterwork, Discourses Concerning Two New Sciences, was set in the Venetian arsenal, and to it Galileo appended a table of the parabolic paths that could be expected from cannons shot at various elevations.4 In some sense Galileo turned inside-out a much older problem, one that had haunted military engineers of sixteenth-century Italy—and Galileo had been trained, and trained others, in military engineering.5 State organizers of war and captain generals were less interested in the implications the arts of fortifications and artillery held for the existing science of natural motion than in the necessity to reduce to a science, that is, a coherent body of knowledge, the rules for manufacturing cannons, planting artillery battery, aiming guns, and fortifying camps, cities, and castles.What Galileo gives us is recognizable as early physics, as a sophisticated mechanical science, a neat triumph of mathematical method in natural philosophy. But the ways and means by which mathematics came together with natural philosophy to address problems of both technology and nature are by no means neat. My claim is that attention to the military sphere will help us sort out some of those ways and means. The curious thing about the historiography on the relationship between early modern science and warfare is that the fact of a connection seems to have been taken for granted, while the implications have seldom been investigated.6 This essay is an attempt to trace those implications by [End Page 373] looking at a mathematician who specifically tried to reduce to a mathematical science the military arts, Niccolò Tartaglia.7 Tartaglia's story shows how the minutia of Aristotelian philosophy was transmuted in early attempts to understand cannonshot...

Fichte's System of Ethics, published in 1798, is at once the most accessible presentation of its author's comprehensive philosophical project, The Science of Knowledge or Wissenschaftslehre, and the most important work in moral philosophy written between Kant and Hegel. Fichte's ethics integrates the discussion of our moral duties into the systematic framework of a transcendental theory of the human subject. Its major philosophical themes include the practical nature of self-consciousness, the relation between reason and volition, the essential role of the (...) drives in human willing, the possibility of changing the natural world, the reality of one's own body, the reality of other human beings, and the practical necessity of social relations between human beings. This volume offers a translation of the work together with an introduction that sets it in its philosophical and historical contexts. (shrink)
