The Decisive Treatise

The Decisive Treatise
A legal and philosophical argument for studying philosophy within Islam.
About this book
The Decisive Treatise asks whether philosophy is permitted, forbidden, or required by religious law. Ibn Rushd argues that demonstration and revelation cannot finally contradict when both are properly understood, and that qualified readers have a duty to investigate creation rationally. The text is brief but important, because it frames philosophy not as foreign curiosity but as a disciplined form of obedience to truth.
