Constantin K. Zurayk (Arabic: قسطنطين زريق‎) was a prominent and influential Syrian Arab intellectual who was one of the first to pioneer and express the importance of Arab nationalism. He stressed the urgent need to transform stagnant Arab society by means of rational thought and radical modification of the methods of thinking and acting. He developed some ideas, such as the "Arab mission" and "national philosophy", which were to become key concepts for Arab nationalist thinkers, and in more recent years was a strong proponent of an intellectual reformation of Arab society, emphasizing the need for rationalism and an ethical revolution.
