Logic Arguments in the Medieval Muslim Philosophy and Theology: Al-Ghazali, Averroes, Ibn al-Munadżdżim

Abstract

Philosophical legacy of ancient Greeks greatly influenced the shaping of Medieval Islamic thought. Especially popular were writings of Aristotle, particularly his logical works. Muslims very quickly noticed that logic is a very practical tool, both in discussions with non-Muslims, as well as polemics within Islam itself. This article focuses on three thinkers:
Al-Ghazali, Averroes and Ibn al-Munajjim.

Al-Ghazali’s ideas exemplify how logic was used in theological disputes within Islam itself. Averroes , in turn, in one of his major works „The Decisive Treaty”, tries to refute accusation aimed at impiety of philosophers. Ibn Rushd shows that philosophy is not contrary to the principles of faith but just opposite. He states that The Quran encourages to learn and deepen the philosophy, because it is the best way to cognition of the truth and it based on syllogistic deduction. Concluding, the article presents how logic was used in disputes with non-Muslims by referring to Ibn al-Munajjim letter.
