I defend the view that many biological categories are defined by homology against a series of arguments designed to show that all biological categories are defined, at least in part, by selected function. I show that categories of homology are `abnormality inclusive'—something often alleged to be unique to selected function categories. I show that classifications by selected function are logically dependent on classifications by homology, but not vice-versa. Finally, I reject the view that biologists must use considerations of selected function (...) to abstract away from variation and pathology to form a canonical description of a class of biological systems.

The international community has long been affected by the political, philosophical and ethical issues surrounding the practice of tyrannicide, defined as the targeted killing of a tyrant. However, there exists no specific international legal instrument that concerns the practice of tyrannicide, rendering the legitimacy of the practice ambiguous. This paper aims to investigate the issue of tyrannicide and offers a number of speculative arguments concerning its legal-philosophical status. It finds that there are essentially two arms of international legal jurisprudence that (...) may regulate the practice of tyrannicide. The first is largely prohibitive and is based on the derived legal arguments against assassination involving the element ofperfidy, relevant extradition law, provisions in the Hague, Geneva and New York Conventions, and the prohibition on the use of force in the UN Charter. The second position, though far more radical and speculative, is more permissive regarding the moral legitimacy of tyrannicide. This position is based on arguments from the classical international theorists Gentili, Grotius and Vattel, contemporary human rights standards, the principle of humanitarian intervention, the duty to protect, and legal category of hostis hutnani generis. It is argued that though the vast majority of international legal principles are indicative ofthe illegality oftyrannicide, that the practice may nevertheless be philosophically legitimated under humanitarian principles.

There have been two Japanese Nobel laureates in chemistry, three in physics, and one in the category of medicine or physiology. This relatively small number has been attributed to shortcomings in Japanese science. The award of the Physics Prize in 1949 to Hideki Yukawa and to his colleague Sin'itirô Tomonaga in 1965 gave public evidence of how Japanese could make outstanding individual contributions to science. Paradoxically, the Prize also reinforced a belief that such men formed part of a traditional (...) hierarchical system. This essay examines how the Nobel Prize has been represented in Japan.

Emmanuel Levinas’s work on the ethical responsibility of the face-to-face relation offers an illuminating context or clearing within which we might better appreciate the work of Simone Weil. Levinas’s subjectivity of the hostage, the one who is responsible for the other before being responsible for the self, provides us with a way of re-encountering the categories of gravity and grace invoked in Weil’s original account. In this paper I explore the terrain between these thinkers by raising the question of eating (...) as, in part, an ethical act. Weil’s conception of grace refers to the state of decreation in which the utter humility of the self moves toward a kind of disintegration and weightlessness. This weightlessness, which Weil contrasts to the gravity of terrestrial weight, might be thought of in terms of the subject’s fundamental responsibility for the other, especially in terms of the injunction “Thou shalt neither kill nor take the food of thy neighbour.” Taking the place of the other, taking the food from the mouth of the other, is the ethical dilemma facing the subject as hostage and an elaboration of this situation may provide us with steps toward a radical questioning of anorexia as—at least inpart—an ethical rather than purely medical condition.
