Despite the vast amount of information and the number of factual details assembled during the past century by Western scholarship in the fields of orientalism and comparative religion, many gaps still exist in the knowledge of the various religions of the world, even on the level of historical facts. Moreover, until recently most of the studies carried out within these fields have suffered from a lack of metaphysical penetration and sympathetic insight. One of the most notable omissions in Western studies of the religions of the East, and of Islam in particular, has occurred in the case of Shi’ism. Until now Shi’ism has received little attention; and when it has been discussed, it has usually been relegated to the secondary and peripheral status of a religio-political “sect,” a heterodoxy or even a heresy. Hence its importance in both the past and the present has been belittled far more than a fair and objective study of the matter would justify.
