Relationship between Critical Rationality and Social Morality

This article aims at introducing the idea of critical rationality from Popper's point of view and recognizing its relationship with social morality. Popper is a philosopher who cares for improving morality within human society and emphasized the role of some moral principles in rationality and obtaining knowledge. He believes that the rational interactions of humanbeings should be based on "tolerance", "scientific modesty" and "respect for other's views". This article introduces the idea of "critical rationality" after reviewing the criticisms made by Popper regarding traditional epistemological models. Then, the authors explore its relation with morality and discuss some resulted moral principles such as "equality of human beings in knowledge and value", "scientific modesty", "critical dialogue" and "moral autonomy". They assume that Popper's view can serve as a directive in social morality.
