There are, broadly speaking, two ways to think about rationality, as defined in the following passage: ‘Reason’ for a long time meant the activity of understanding and assimilating the eternal ideas which were to function as goals for men. Today, on the contrary, it is not only the business but the essential work of reason to find means for the goals one adopts at any given time. To use what Horkheimer called objective reason, and what others have called expressive or (...) non–instrumental reason, is to reflect on one's goals, to attempt to determine what preferences one ought to hold. On the other hand, to use what Horkheimer called subjective reason is to ‘be concerned with means and ends, with the adequacy of procedures for purposes more or less taken for granted’, that is, to be instrumentally rational. This contrast between non-instrumental and instrumental reason is at the heart of many contemporary social and philosophical disputes. 1. (shrink)

This article is an attempt at a systematic account of decision making under greater uncertainty than what traditional, mathematically oriented decision theory can cope with. Four components of great uncertainty are distinguished: (1) the identity of the options is not well determined (uncertainty of demarcation) ; (2) the consequences of at least some option are unknown (uncertainty of consequences); (3) it is not clear whether information obtained from others, such as experts, can be relied on (uncertainty of reliance); and (4) (...) the values relevant for the decision are not determined with sufficient precision (uncertainty of values). Some possible strategy types are proposed for each of these components. Decisions related to environmental issues are used to illustrate the proposals. (shrink)

In recent years the idea of geoengineering climate has begun to attract increasing attention. Although there was some discussion of manipulating regional climates throughout the l970s and l980s. the discussion was largely dormant. What has reawakened the conversation is the possibility that Earth may be undergoing a greenhouse-induced global wamring, and the paucity of serious measures that have been taken to Prevent it. ln this paper Iassess the ethical acceptability of ICC, based on my impressions of the conversation that is (...) now taking place. Rather than offering a dispassionate analysis, I argue for a point of view. I propose a set of conditions that must be satisfied for an ICC project to be morally permissible and conclude that these conditions are not now satisfied. However, research on ICC should go forward.. (shrink)

Climate change is a global problem that is predominantly an intergenerational conflict, and which takes place in a setting where our ethical impulses are weak. This "perfect moral storm" poses a profound challenge to humanity. This book explains how the "perfect storm" metaphor makes sense of our current malaise, and why a better ethics can help see our way out.
