Our aim in this article is to investigate Khajeh Nasir`s effective role in emergence, growth and development of triple paradigms of Islamic philosophy, that are, Masha’, Ishraq and al-Hekmah al-Motealiyeh. Thus, first we present a summary of the meaning of “paradigm” and then discuss Tusi`s role in the development of triple paradigms of Islamic philosophy. We believe that, by using an interactive approach, Khajeh Nasir has attained a new approach to understand the paradigms. He is the first thinker in Islamic world who created a constructive and effective interaction between two paradigms of Masha’ and Ishraq, and paved the way for the emergence of al-Hekmah al-Motealiyeh. This can be explained with regard to either the conceptualization of al-Hekmat al-Motealiyeh or epistemological approach. Al-Hekmah Al-Motealiyah was influenced a lot by Tusi.
