Practical rationality is the rationality which becomes a norm for man. And for the purpose of this work rationality is taken in relation to a community of persons or society or state not simply a single person. Practical rationality is normative since it directs people to choose the most rational and reasonable moral options in order to organize themselves as a rational moral community. It aims at a practical goal. It articulates in a suitable manner all that is necessary to make a community take the most rational decisions and choices for social cooperation. Granted practical rationality gives a community the norms of organizing themselves, it is not instrumental rationality, which aims solely in achieving a particular goal in life or a particular good. Rather, practical rationality sets a community on a practical rational foundation upon which the community can organize it citizen in most rational manner. We adopt theoretical analysis in our exposition.
