ibn al-Haytham

"The seeker after truth is not one who studies the writings of the ancients and, following his natural disposition, puts his trust in them," Ibn al-Haytham wrote in Doubts Concerning Ptolemy, "but rather the one who suspects his faith in them and questions what he gathers from them, the one who submits to argument and demonstration."

I love this quote, especially Ibn al-Haytham's emphasis on what he called demonstration--what we would call experimentation. This is a turning point not just in his career, but in the history of the world. From this moment on, assertions about the physical world would be subject to testing through experimentation.
