Al-Ghazālī did not regard himself as a philosopher, given that during his period in Islamic intellectual history, philosophy was associated with the Aristotelian tradition promulgated primarily by Avicenna (Ibn Sina), and, for al-Ghazālī, Avicenna was undoubtedly considered to be an unbeliever whose philosophical views (such as his commitment to the eternity of the world) fell outside the scope of orthodox Sunni Islam. There would be a serious stigma attached, from the perspective of Islamic orthodoxy, with al-Ghazālī identifying with the philosophers. Instead, al-Ghazālī regarded himself primarily as a Sufi (mystic), theologian, and jurist.
Yet despite his aversion to particular philosophical theses, it is clear that Al-Ghazālī is not only sympathetic to particular disciplines and methodologies of philosophy (for example, logic and ethics), but produces work that would certainly qualify as philosophical both in his day and ours. Indeed, he contributed immensely to the history of Islamic philosophy and the history of philosophy more generally, and he is considered to be one of the greatest and most influential thinkers in Islamic intellectual history. Al-Ghazālī’s philosophical work spans epistemology, metaphysics, philosophy of mind, natural philosophy, and ethics. His philosophical work had a wide-reaching influence within the Islamic world, and his Incoherence of the Philosophers, in particular, was well-received by other medieval philosophers and the Latin philosophical tradition.
