al-Ghazali

Al-Ghazali (1058-1111) was a Persian polymath and one of Islam's most influential theologians and philosophers. Initially a professor at the Nizamiyya madrasa in Baghdad, he experienced a spiritual crisis that led him to abandon his prestigious position and pursue Sufi mysticism. His masterwork, The Revival of the Religious Sciences, synthesized Islamic law, theology, philosophy, and mysticism into a comprehensive guide for religious life. In The Incoherence of the Philosophers, he systematically refuted Aristotelian philosophy as practiced by Muslim peripatetics, particularly their views on God's knowledge, the eternity of the world, and bodily resurrection. His Deliverance from Error provides an autobiographical account of his intellectual journey through skepticism to certainty through mystical experience. Al-Ghazali's integration of rational theology with spiritual experience profoundly shaped Islamic thought, earning him the title "Proof of Islam." His work influenced later Islamic philosophy and was studied by medieval Christian scholars including Thomas Aquinas.
