Ghazali allowed that mathematics, logic, and even the natural sciences could lead to true conclusions, but wherever they conflicted with the revelations, they were wrong. But if science is right only when it reaches the same conclusions as revelation, we don’t need science. All the truth we need we can get from the revelations. Some of the philosophers struck back. Ibn Rushd (known to Europeans as Averroes) wrote a riposte to Ghazali called The Incoherence of the Incoherence , but it did little good: when the smoke cleared, Ghazali had won the day.
