Ài Sīqí is the pen name of Li Shengxuan, a Yunnan Mongol Chinese philosopher and author. He was born in Tengchong, Yunnan, later traveling to Hong Kong, where he studied English and French at a Protestant school and was exposed to Sun Yat-sen’s Three Principles of the People and Marxism. He read a great deal of Marxism, including the Communist Manifesto, in Japanese translation. This reading is the root of Ai’s most important works, Dialectical Materialism and Historical Materialism (歷史唯物主義與辯証唯物主義) and Philosophy for the Masses (大眾哲學)(1948). He was a delegate to the 1st, 2nd and 3rd National People's Congress.
