The Role of Epistemological Foundations in Discovering Psychological Realities

The present paper seeks to identify the role of epistemological foundations in psychology. Using a descriptive-analytical method, relying on Islamic sources and referring to psychology sources, it reviews two foundations: "the possibility of cognition" and "diversity of the ways of cognition", and then examines their role in discovering psychological realities.The research findings show that establishing the foundation of "possibility of cognition" shows that it is possible to have absolute, unchangeable and beyond time- place kinds of cognition about human acts under certain conditions. This helps, psychology to get out of its insecure and unstable condition and achieves principles which have high confidence. Similarly, accepting this foundation strengthens the critical attitude about the human sciences and urges scientists to make greater efforts to acquire professional kinds of knowledge. According to the "diversity of ways of cognition", man’s widespread and comprehensive cognition and his characteristics will be possible by using all the available methods and it will be possible to have true and comprehensive knowledge of man by relying on one single method. With the diversity of methods, it is possible to produce religious science, including Islamic psychology, especially on topics or concepts referred to religious texts.
