Concept
Transcendent theosophy or al-hikmat al-muta’āliyah (حكمت متعاليه), the doctrine and philosophy developed by Persian philosopher Mulla Sadra (d.1635 CE), is one of two main disciplines of Islamic philosophy that are currently live and active. The expression al-hikmat al-muta’āliyah comprises two terms: al-hikmat (meaning literally, wisdom; and technically, philosophy, and by contextual extension theosophy) and muta’āliyah (meaning exalted or transcendent). This school of Mulla Sadra in Islamic philosophy is usually called al-hikmat al-muta’āliyah. It is a most appropriate name for his school, not only for historical reasons, but also because the doctrines of Mulla Sadra are both hikmah or theosophy in its original sense and an intellectual vision of the transcendent which leads to the Transcendent Itself. So Mulla Sadra’s school is transcendent for both historical and metaphysical reasons. When Mulla Sadra talked about hikmah or theosophy in his words, he usually meant the transcendent philosophy. He gave many definitions to the term hikmah, the most famous one defining hikmah as a vehicle through which “man becomes an intelligible world resembling the objective world and similar to the order of universal existence”. Mulla Sadra's philosophy and ontology is considered to be just as important to Islamic philosophy as Martin Heidegger's philosophy later was to Western philosophy in the 20th century. Mulla Sadra brought "a new philosophical insight in dealing with the nature of reality" and created "a major transition from essentialism to existentialism" in Islamic philosophy. A concept that lies at the heart of Mulla Sadra's philosophy is the idea of "existence precedes essence", a key foundational concept of existentialism. This was the opposite of the idea of "essence precedes existence" previously supported by Avicenna and his school of Avicennism as well as Shahab al-Din Suhrawardi and his school of Illuminationism. Sayyid Jalal Ashtiyani later summarized Mulla Sadra's concept as follows: "The existent being that has an essence must then be caused and existence that is pure existence .
