Abstract

We can find a common point between the Islamic peripatetic (of Al-Farabi, Ibn Sina (Avicenna), and Ibn Rushd (Averroes) (1126-98)) and Enlightenment philosophies based on their use of rationality. The overall objective of this paper is to present some of the different aspects of rationality in these two philosophies. We can find a kind of congruence between these philosophies. They commonly defend universality, unity, and permanence of reason. They do not accept a priori truths, and emphasize the limits of rationality. On their respective views, rationality corrects its mistakes gradually. This suggests that we can have a dialogue between Western Enlightenment and Islamic cultures through rationality. This paper aims to reconstruct Islamic peripatetic and Enlightenment philosophies on the basis of their notion of the rationality. It tries to show this by referring to the major Muslim peripatetic philosophers and to Enlightenment philosophy as described by Ernst Cassirer (1874-1945).
