ABSTRACT
Chapter (2) discusses value and uncertainty and their dependence on choice behaviour. The choice behaviour was in no way necessarily connected with decision. In this chapter, we shall discuss the content of mathematical (or logical) decision, and several problems arising in the introduction of decidability into choice. It is necessary to note that we can permit several forms of decision, depending on whether it is complete, partial or probabilistic. Although we talk in terms of probabilities, any other valid truth value measure would do.
