Tao Te Ching

“Europe knows Persian poetry chiefly through Omar Khayyam, an advanced freethinker, constrained by prudence to bridle his tongue. He rejected theology with patient scorn, boasted of stealing prayer rugs from a mosque, and raised intoxication almost to a world philosophy. Picture him as an old savant quietly content with cubic equations, a few constellations, astronomic charts, and sharing an occasional cup with fellow scholars.”

— Will Durant 1885 – 1981 CE via Shan Dao
Philosophy apostle and popularizer of history's lessons
