Al-Ghazali
Al-Ghazali entered philosophy as one of its most brilliant practitioners and emerged as its most unsettling critic: a thinker who used reason to expose reason’s limits, then turned to disciplined spiritual knowledge as the mind’s truer home.

Timeline
Birth in Tus
**1058** — Al-Ghazali is born in Tus in the region of Khorasan, entering a Persian scholarly world that was already connected to the great theological and philosophical debates of the Islamic east. His later life would turn that world into an argument about certainty, inwardness, and the authority of revelation.
Studies under al-Juwayni
**1070** — As a young student, al-Ghazali studies with Abu al-Ma'ali al-Juwayni in Nishapur, absorbing the methods of Ash'ari theology and legal reasoning. This training gives him the conceptual discipline that later makes his critique of the philosophers so formidable.
Appointment to the Nizamiyya in Baghdad
**1091** — Al-Ghazali becomes a leading teacher at the Nizamiyya madrasa in Baghdad, one of the most prestigious academic posts of his age. The appointment places him at the center of scholarly and political authority, where philosophy, theology, and law met under intense scrutiny.
Spiritual and epistemic crisis
**1095** — Al-Ghazali undergoes the crisis later described in al-Munqidh min al-Dalal, during which confidence in his public role and in discursive certainty collapses. The event becomes the philosophical prelude to his turn toward withdrawal and spiritual discipline.
Withdrawal from public teaching
**1095** — He leaves Baghdad and enters a period of retreat and itinerancy, seeking the certainty that argumentative success had not provided. This withdrawal is central to the later image of al-Ghazali as a thinker who moved from scholastic authority to inward reform.
Composition of Tahafut al-Falasifa
**1095** — Al-Ghazali writes The Incoherence of the Philosophers, his most famous critique of Avicennian metaphysics. The work attacks specific doctrines that he believes threaten divine omnipotence, prophecy, and the intelligibility of revelation.
Return to teaching and writing
**1096** — After years of retreat, al-Ghazali resumes teaching and composing works that integrate theology, law, and Sufi ethics. His public return marks the transformation of his crisis into a constructive intellectual program.
Completion of Ihya' 'Ulum al-Din
**1106** — Al-Ghazali completes the Revival of the Religious Sciences, his great synthesis of ethical discipline, devotional practice, and spiritual psychology. The work becomes one of the most influential texts in Sunni religious life.
Death in Tus
**1111** — Al-Ghazali dies in Tus, ending a career that had reshaped the relation between philosophy, theology, and mysticism in the Islamic world. His legacy immediately becomes a matter of interpretation, praise, and debate.
Ibn Rushd's reply in Tahafut al-Tahafut circulates
**1195** — Averroes’s reply to al-Ghazali becomes one of the classic philosophical counterattacks in medieval Islamic thought. It challenges al-Ghazali’s account of causation and his treatment of demonstrative knowledge, keeping the controversy alive for later centuries.
Latin translations broaden al-Ghazali's reach
**1263** — Latin versions of al-Ghazali’s works, especially those connected with the philosophical and polemical corpus, circulate in medieval Europe. They help make him part of scholastic discussions about Islam, philosophy, and the relation between reason and faith.
Modern reappraisal in scholarship
**20th century** — Modern historians of Islamic philosophy and theology revise the older story that portrayed al-Ghazali as the destroyer of philosophy. New scholarship presents him as a complex system-builder whose critiques were inseparable from his theological, ethical, and mystical commitments.
