A translation of the Persian book Mas'aleh-ye Shinakht by the great thinker and reformer Ayatollah Murtada Mutahari. With ample citations from the Qur'an and other traditional Islamic texts, Mutahhari discusses the concept of knowledge from an Islamic perspective. Not limiting himself to the Islamic source texts, Mutahhari also engages with the works and views of philosophers including Ghazali, Ibn Sina, Kant and Hegel. In all this is a concise epistemological discussion that covers a wide range of issues and provides a spiritual approach to questions about knowledge which are vital to the human experience.
