The philosophical dispute on whether logic is a part of philosophy or just an Organon, initiate a further philosophical debate on the very connection of logic to a given philosophical and metaphysical systems. The first part of the paper offers an analytical account of how Ibn Taymiyya (1263-1329 AD.) looked at Aristotelian logic especially Aristotle’s theory of syllogism and his theory of definition. In the second part I tried to offer a synthetic account of Ibn Taymiyya’s logic and how his criticism was constructed upon five underlying rules and principles. While the third part offers some explanatory comments on the issues of intellect and the possible contradiction between reason and revelation and how Ibn Taymiyya looked at it.
