Abstract

In this Chapter attention will be shifted to some issues that have emerged in our discussions on rationality. This shift of attention will allow us an entry point into discussions on the epistemic nature of fuzzy rationality. In the previous discussions, the concepts of optimal rationality and sub-optimal rationality were introduced. Decision-choice rationality in the framework of classical paradigm was defined in terms of optimal behavior in all aspects of activities of cognitive agents. The deviations of this optimality were defined as suboptimal rationality. The concept of irrationality was bypassed since its explication, meaning and usefulness depend on those of the concept of rationality. It will be argued that irrationality and rationality constitute polarity (or extreme) of cases of decision-choice behavior between which deferential degrees of sub-optimal rationality fall. Such degrees of sub-optimality lend themselves to fuzzy topology and hence best handled in the framework of fuzzy paradigm composed of logic and corresponding mathematics.
