Karl Popper and the Iranian Intellectuals Ali Paya Abstract The ways in which Popper's ideas have been introduced to Iranian society will be discussed, and the reactions of several prominent Jranian intellectual groups, namely, the leftists, the Heideggerians, the religious conservatives, the religious intel­ lectuals and the moderate seculars, to Popper's views wilJ be critically appraised. The upshot of the paper is that while Popper's views have been used and misused in the power struggle between various groups in post-revolutionary ]ran, they also have been instrumental in creating colJective intentionalities and shared understandings con­ cerning a range of important concepts in such diverse fields as epistemology, politics, culture, social action, and religious beliefs. Introduction In this paper, following a brief historical background concerning the intro­ duction of Popper's ideas to the Iranian public, I shall concentrate on the approaches taken by a number of distinct Iranian intellectual groups toward Popper's views. The groups in question are the leftists, the Heideggerians, the religious conservatives, the religious intellectuals and the moderate seculars.
