Al-Ghazālī
Abū Ḥāmid al-Ghazālī
Theologian-Sufi who challenged the philosophers and reconciled reason with mysticism.
Overview
One of Islam's most influential thinkers, al-Ghazālī mastered philosophy in order to critique it. In The Incoherence of the Philosophers he attacked the falāsifa — especially Avicenna — on the eternity of the world, God's knowledge of particulars, and bodily resurrection, and questioned the necessity of causal connection (anticipating Hume). After a spiritual crisis he embraced Sufism, and in The Revival of the Religious Sciences he reintegrated mystical experience with orthodox Islam, reshaping Islamic thought for centuries.
What they supported — and why
Critique of the philosophers
SupportedOn the world's eternity, God's knowledge of particulars, and bodily resurrection, the philosophers' claims are undemonstrated and contradict faith.
WhyTheir arguments overreach what reason can prove, so their confident metaphysical conclusions must be rejected where they clash with revelation.
Critique of necessary causation (occasionalism)
SupportedThe observed 'connection' between cause and effect is not logically necessary; God is the true cause of all events.
WhyFire burning cotton is a habitual conjunction we witness, not a necessity we can prove — God could will otherwise.
The primacy of mystical experience
SupportedThe deepest certainty about God comes through Sufi 'tasting' (dhawq), not argument alone.
WhyAfter doubt undermined the senses and reason, he found firmer certainty in immediate experience and the light God casts into the heart.
