The Iranian Research Institute of Philosophy (IRIP; Persian: مؤسسه پژوهشی حکمت و فلسفه ایران) is a public research institute in Tehran, Iran. History In September 1974, Farah Pahlavi Empress of Iran commissioned Seyyed Hossein Nasr, Head of the Empress's Private Bureau, to establish and lead the Imperial Iranian Academy of Philosophy. It was the first academic institution to be founded upon the principles of philosophical Traditionalism. Nasr was a Professor of History of Science and Philosophy at University of Tehran who also served for several years as president of Sharif University of Technology in Iran.
