题目：Interdefinabilities in the logic of norms, values, and decisions

摘要：Can preferences be defined in terms of choices? Can “good” be defined in terms of “better”? Conversely, can “better” be defined in terms of “good”? Can deontic concepts be defined in terms of evaluative ones? This presentation is an attempt to provide a comprehensive account of these and some related definability issues concerning concepts that are relevant in logic and decision theory. A comparison between different proposed definitions may help us to clarify the more fundamental question what is required for such a definition to be acceptable.

He was also a member of two temporary Commissions on environmental policies appointed by the Swedish Government, expert advisor to a 1999–2000 Swedish government committee the kemikaliekommittén, and a member of the board of the MISTRA project New Strategy for the risk management of chemical substances. Since December 2000, Hansson has been a member of forskningsberedningen, the Swedish government’s advisory board of researchers .
