There are strong reasons for assuming that Thomas Aquinas conceived of God’s existence in terms of logical necessity in a broad sense. Yet this seems to stand in some tension with the fact that he excludes the possibility of a priori arguments for the existence of God. One apparently attractive way of handling this tension is to use a two-dimensional framework inspired by Saul Kripke. Against this, this article demonstrates that a Kripke-inspired framework is inapt in this context because it (...) allows for the conceivability of God’s non-existence, thereby rendering his non-existence possible in some important, and for Aquinas inacceptable, sense. Drawing on David Chalmers, the article submits that the existence of God can only be necessary if God’s non-existence is ideally inconceivable. On the basis of Aquinas’ own understanding of God, however, the article argues further that God’s non-existence in fact is inconceivable. The alleged conceivability of God’s non-existence is ultimately due to our (human) inability to grasp the nature of being, whereas creatures who grasp the nature of being are unable to conceive of God’s non-existence. This removes God’s non-existence from the realm of relevant conceivability and, therefore, from the range of possible worlds. (shrink)

Does it work? This question lies at the very heart of the kinds of controversies that have surrounded complementary and alternative medicines (such as herbal medicine) in recent decades. In this article, I argue that medical anthropology has played a pivotal and largely overlooked role in taking the sham out of the placebo effect with important implications for what it means to say a therapy or drug `works'. If pharmacologists and clinicians have corporeally located the concept of efficacy in terms (...) of bio-availability, pharmacodynamics and pharmacokinetics, and herbalists in terms of a herbal revitalizing of the body's own vis medicatrix naturae, from the early 20th century onwards medical anthropologists (especially those who became interested in the `savage mind') have built up an equally rigorous theory of symbolic efficacy in terms of narratives, symbols and a kind of cognitive homeostasis. It was precisely as a mediating link between the somatic and the symbolic that I suggest a decriminalized placebo effect (as opposed to suggestion) could emerge in the middle of the 20th century. Taking the example of St John's Wort, I go on to show how notions of symbolic efficacy, spillover placebo efficacy and bio-efficacy co-circulate in recent attempts by herbalists, clinicians and pharmacologists to address the question of whether or not this herbal remedy `works' in the treatment of depression.

Selection in reproductive medicine today relies on normative assessments of what ‘good life’ consists of. This paper explores the terms under which such assessments are made by focusing on three particular concepts of ‘quality’: quality of life, biological quality and population quality. It is suggested that the apparently conflicting hypes, hopes and fears that surround reproductive medicine can co-circulate because of the different forms of normative assessment that these concepts allow. To ensure clarity in bioethical deliberations about selection, it is (...) necessary to highlight how these differing forms of assessment are mobilized and invoked in practices of and debates about reproductive medicine.
