The Incoherence of the Philosophers (Tahâfut al-falâsifa) is an attempt by 11th century Sunni theologian and mystic al-Ghazâlî to refute the doctrines of philosophers such as Ibn Sina (often latinized Avicenna) or al-Fârâbî (Alpharabius), which he viewed as heretical for favoring Greek philosophy over the tenets of Islam. Al-Ghazâlî’s methodological principle was that in order to refute the assertions of the philosophers, one must first be well versed in their ideas; indeed, another work of his, Doctrines of the Philosophers (Maqāsid al-Falāsifa), gives a comprehensive survey of the Neoplatonic philosophy he sought to refute in the Incoherence.

The Incoherence, besides its other qualities, is noteworthy in that it is now regarded as a landmark work in philosophy itself. Ibn Rushd (Averroes), in response, penned the Incoherence of the Incoherence (Tahāfut al-Tahāfut), a turning point away from Neoplatonism to Aristotelianism.

In modern times, most allegations of ‘incoherence’ levied against philosophy come not from the direction of religion, but rather, from scientists’ allegations that their discipline has made philosophy redundant, supplanting it by a better set of tools to investigate the world. The perhaps most well-known example of this is Stephen Hawking’s infamous assertion that ‘philosophy is dead’, but similar sentiments are readily found. While the proponents of such allegations have not always shown shown al-Ghazâlî’s methodological scrupulousness in engaging with the body of thought they seek to refute, these are still weighty charges by some of the leading intellectuals of the day.
