This paper would seek to explain the philosophical foundations of symbol and allegory in Hikmat-al-muta’aliya through a descriptive-analytical method. Its core concept is that symbol and allegory are, on the one hand, rooted both in Ideal and Intellectual worlds and, on the other, that they are tied to artist’s purifying imagination. Accordingly, this leads to discussions on imagination’s role in the embodiment of meanings and animating of the substances and an argument on the univocity of symbols and allegories and their correspondence to human’s existential chain of orders. The first part of the paper hence introduces the philosophical issues regarding this understanding of symbol and allegory and the second part provides, while giving some examples as well, the philosophical backgrounds for them.
