The Incoherence of the Philosophers (Arabic: تهافت الفلاسفة Tahāfut al-Falāsifah) by Al-Ghazali (1056-1111) is one of the major works of Arabic and Islamic philosophy. In 20 chapters, it critiques the ideas of Avicenna, Al-Ghazali's leading precursor in the Greek-influenced tradition of falsafa. Al-Ghazali has sometimes been blamed for the decline of Muslim science, partly because of a scepticism about causality that has been compared to that of David Hume. Nevertheless, his influence proved decisive for the synthesis of philosophy and Muslim theology, and anticipated later critiques of Aristotelian science.
