Al-Razi
Islamic
A physician who trusted observation over authority, and reason over revelation, further than almost anyone of his age dared.
Al-Razi ran hospitals in Rayy and Baghdad and wrote medical works so careful that they were taught in Europe for centuries, including the first clinical account of the difference between smallpox and measles. As a philosopher he was a startling rationalist, holding that reason is given to every person and needs no prophet to complete it, that the soul can be healed by the same patient method as the body, and that no authority should be believed against the evidence. Even thinkers who detested his conclusions could not ignore the rigor with which he reached them.
