Illuminationism in the context of "Holistic"

Shihāb ad-Dīn Yahya ibn Habash Suhrawardī (Persian: شهاب‌الدین سهروردی, also known as Sohrevardi) (1154–1191) was a Persian philosopher and founder of the Iranian school of Illuminationism, an important school in Islamic philosophy. The "light" in his "Philosophy of Illumination" is the source of knowledge. He is referred to by the honorific title Shaikh al-ʿIshraq "Master of Illumination" and Shaikh al-Maqtul "the Murdered Master", in reference to his execution for heresy. Mulla Sadra, the Persian sage of the Safavid era described Suhrawardi as the "Reviver of the Traces of the Pahlavi (Iranian) Sages", and Suhrawardi, in his magnum opus "The Philosophy of Illumination", thought of himself as a reviver or resuscitator of the ancient tradition of Persian wisdom. Suhrawardi provided a new Platonic critique of the peripatetic school of Avicenna that was dominant at his times, and that critique involved the fields of Logic, Physics, Epistemology, Psychology, and Metaphysics.

Ṣadr ad-Dīn Muḥammad Shīrāzī, more commonly known as Mullā Ṣadrā (Persian: ملا صدرا; Arabic: صدر المتألهین; c. 1571/2 – c. 1635/40 CE / 980 – 1050 AH), was an Iranian Twelver Shi'i Islamic mystic, philosopher, theologian, and ‘Ālim who led the cultural renaissance in the country during 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 philosophies into what he called the Transcendent Theosophy or al-hikmah al-muta’āliyah.

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 God, and thus differs considerably from the individual, moral, and/or social, questions at the heart of Russian, French, German, or American Existentialism.

According to divine illumination, the process of human thought needs to be aided by divine grace. It is the oldest and most influential alternative to naturalism in the theory of mind and epistemology. It was an important feature of ancient Greek philosophy, Neoplatonism, medieval philosophy, and the Illuminationist school of Islamic philosophy.
