Philosophy is a consistent and comprehensive thought actvity on being, knowledge and values. The main character of this thought actvity is that it is ratonal. Unfortunately, people can be ratonal and ant-ratonal. Representatves of the ant-ratonal thought in Islamic culture are Salafsm or literalism. Ratonality, enables the development in every sense. However, ant-ratonality prevents the development in any sense. Clear example of this is the madrasa traditon in our culture. Logic is the study of the methods and principles used in distnguishing correct from incorrect reasoning. Even this defniton, describes the importance of logic in philosophy.

The basic conditon of critcism is an independent mind. The success of the actvity of philosophical thought and existence of a independent mind only depends on development of this critcal mentality
