Ḥayy ibn Yaqẓān () is an Arabic philosophical novel and an allegorical tale written by Ibn Tufail ( – 1185) in the early 12th century in Al-Andalus. Names by which the book is also known include the ('The Self-Taught Philosopher'); and English: The Improvement of Human Reason: Exhibited in the Life of Hai Ebn Yokdhan. Ḥayy ibn Yaqẓān was named after an earlier Arabic philosophical romance of the same name, written by Avicenna during his imprisonment in the early 11th century, even though both tales had different stories. The novel greatly inspired Islamic philosophy as well as major Enlightenment thinkers. It is the most translated text from Arabic, after the Quran and the One Thousand and One Nights.
