モッラー・サドラー
Although Existentialism as defined nowadays is not identical to Mulla Sadra's definition, he was the first to introduce the concept. According to Mulla Sadra, "existence precedes the essence and is thus principal since something has to exist first and then have an essence." It is notable that for Mulla Sadra this was an issue that applied specifically to God and God's position in the universe, especially in the context of reconciling God's position in the Qur'an with the Greek-influenced cosmological philosophies of Islam's Golden Era.
