We discuss several features of *coherent choice functions*
- where the admissible options in a decision problem are exactly
those which maximize expected utility for some probability/utility
pair in fixed set ** S** of probability/utility pairs. In
this paper we consider, primarily, normal form decision problems
under uncertainty - where only the probability component of
