Tolerance may be defined in a myriad of ways, but it is by no means a great stretch to agree on Imam Sadr’s vision of tolerance. It is, according to Imam Sadr, an inherently humanist principle: not merely a way of conduct but a philosophy of life, one that permeated all areas of his life like a ripple that widened with his widening intellectual vision and human experience. When I speak of tolerance in Imam Sadr’s thought, I recall images that reflect his tolerance and which I would like to share with you.
