Abu Hamid al-Ghazali (1058–1111), a Persian Sunni scholar, mystic, and polymath, stands as a key figure in Islamic thought, connecting theology, philosophy, and Sufism. Renowned for works such as Tahāfut al-Falāsifa (The Incoherence of the Philosophers) and Iḥyā’ ‘ulūm ad-dīn (The Revival of the Religious Sciences), he challenged Aristotelian philosophy while promoting a unification of orthodox theology with mystical practice.
Scholars like Samuel Zwemer emphasize his role as a mediator between Islamic orthodoxy and Sufi spirituality, highlighting his moral discipline and impact on Jewish thinkers such as Maimonides. Claud Field points to his engagement with philosophy’s “depth,” while Zwemer focuses on his critique of Sufism’s risk of antinomian tendencies. Al-Ghazali’s enduring influence lies in his harmonization of rational exploration with spiritual commitment, shaping Islamic intellectual history through his defense of faith against secularism and his renewal of the ethical and mystical aspects of religion.
