 Traditionally, historians of philosophy have argued that after Ghazzālī in the 11th century CE, philosophical activity in the Persian and Eastern part of the Islamic world was eclipsed and shifted to Islamic Spain. There are those who attribute this to Ghazzālī’s scathing attack on the philosophers, but this is mostly a myth. The Islamic world at the time was so large, and the intellectual milieu so rich and diverse, that no single book could put an end to its philosophy and discursive reasoning. While it is true that Peripatetic philosophy suffered a temporary eclipse in Persia, the reason lies in the socio-political realities of the Saljūq dynasty and the Islamic world’s struggle with external forces like the Crusades. Recent scholarship, such as that by Qasim Kaka'i in the Journal of Andishah-yi Dini, has revealed that the so called period of philosophical decline was actually a thriving era of intellectual activity in the Southern part of Persia where the so called the “School of Shiraz” emerged. This School whose salient feature was to synthesis rationalism, mysticism, intellectual intuition and even popular Sufism was undoubtedly the precursor to the School of Isfahan.
