Iranian modern thinkers in either of the two categories: Western-minded and religious. The most prominent aspect of Western minded thinkers is their emphasis on separation of tradition and modernity. On the other hand, religious thinkers look forward to combining the two. The Western-minded thinkers believe that the most important burden on development in Islamic countries is in the Islamic culture itself. Therefore, they try to minimize the impact of religion on culture and society. The other group which is more religious put the emphasis on encountering the negative responses to modernity by the religious society. They also have the concern for maintaining the religious identity and at the same time pushing the society toward development. The rise of such religious thinkers was also simultaneous with the Persian Constitutional Revolution. In this article I will discuss in detail the views of Murteza Mutahhari and Mehdi Golshani on modern science and technology.
