In this short yet timely book, Dr Ibrahim Kalin, based on his thorough study of the history of philosophy, analyses the categories of reason and rationality within the Islamic intellectual context as it was shaped by the foundational theory underlying the Quran and as developed by the Islamic theological and intellectual tradition. Dr Kalin argues that far from being a self-standing entity, reason functions within a larger context of meaning and existence, intelligibility and moral thinking. He shows clearly how the Quranic perspective of rationality moves us beyond the internal workings of a single, disengaged mind and places us with a larger context of ontological significance.
