Does anybody here know the history and nature of the dispute between this sufi and philosopher? What were they arguing about and why was Ghazzali trying to destruct philosophy?
z10 did you mean the dispute between Ghazali and Avicenna/Ibn Sina? They both had major disputes with each other during their lifetimes.
Al Ghazali wrote the Incoherence of the Philosophers, which essentially attacked the Aristotelian and Greek thought that Ibn Sina relied upon.
Averroes/Ibn Rushd came after Ghazali died, and like Ibn Sina, favoured Greek Philosophy. He wrote a masterful retort to Ghazali's Incoherence of the Philosophers, with a book titled Inchoherence of the Incoherence.
Ghazali didn't turn to sufism until near the end of his life. He went through a spiritual crisis, renounced wealth and travelled as a sufi. So the clash between the two camps was philosophical, and sufism was something that Ghazali turned to very late in his life.
