Ṣadr ad-Dīn Muḥammad Shīrāzī also called Mulla Sadrā (Persian: ملا صدرا‎; also spelt Molla Sadra, Mollasadra or Sadr-ol-Mote'allehin Persian: صدرالمتألهین‎;) (c. 1572–1640) was a Iranian Shia Islamic philosopher, theologian and ‘Ālim who led the Iranian cultural renaissance in the 17th century. According to Oliver Leaman, Mulla Sadra is arguably the single most important and influential philosopher in the Muslim world in the last four hundred years.

Though not its founder, he is considered the master of the Illuminationist, or (Ishraghi or Ishraqi) school of Philosophy, a seminal figure who synthesized the many tracts of the Islamic Golden Age, and Andalusian, philosophies into what he called the Transcendent Theosophy or al-hikmah al-muta’liyah.

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, although his existentialism should not be too readily compared to Western existentialism. His was a question of existentialist cosmology as it pertained to Allah, and thus differs considerably from the individual, moral, and/or social, questions at the heart of Russian, French, German, or American Existentialism.

Hassan Abbasi (born in 1967) is an Iranian political analyst doctrinologist & strategist, the head of the Center for Doctrinal Analysis, an independent political strategic think-tank in the Islamic Republic and also counter-terrorism advanced study center.

Abassi claims to be a basiji of the Iran-Iraq war, and special forces.[1] However, his involvement in Iran-Iraq war (and claims of his volunteer efforts to defend Iran in war times), has bean disputed by General Ali Shamkhani (the Commander of IRGC Navy during the war). General Shamkhani has said: "If Hassan Abbasi and the likes of him would have come to the battleground, we wouldn't have shortage of forces, and the matter [result of the war] would have been different. He was not in the battleground." [2]

Abbasi calls himself a doctor, with a Ph.D. degree, but has always refused to clarify the university from which he graduated or his adviser. He even claims that he has supervised some Ph.D. dissertations, but it has not been confirmed by an independent source. [3][4] Answering questions about his Ph.D. he has said that "Doctorate means Doctrine, meaning someone who can offer Doctrine." [5]
