On the Fourfold Root of the Principle of Sufficient Reason (German: Über die vierfache Wurzel des Satzes vom zureichenden Grunde) was originally published as German philosopher Arthur Schopenhauer's doctoral dissertation in 1813. He revised and re-published it in 1847. The work articulated the centerpiece of many of Schopenhauer's arguments. Throughout his later works he consistently refers his readers to this short treatise as the necessary beginning point for a full understanding of his further writings.
