The Incoherence of the Incoherence

The Incoherence of the Incoherence (Arabic: تهافت التهافت Tahāfut al-Tahāfut) by Andalusian Muslim polymath and philosopher Ibn Rushd (Arabic: ابن رشد, romanizedIbn Rushd, 1126–1198) is an important Islamic philosophical treatise in which the author defends the use of Aristotelian philosophy within Islamic thought.

It was written in the style of a dialogue against al-Ghazali's claims in The Incoherence of the Philosophers (Tahāfut al-Falasifa), which criticized Neoplatonic thought.

Originally written in Arabic, The Incoherence of the Incoherence was subsequently translated into many other languages. The book is considered Ibn Rushd's landmark; in it, he tries to create harmony between faith and philosophy.
