"The use of science in the practice of virtue, is considerable: the man who knows the beauty of virtue will follow it, however possible. Knowing the evil of wrong, he will avoid it, however possible. He listens to worthy praise, and keeps his distance from unworthy praise. From this is derived that science has a part in every virtue, and that ignorance has one in every vice. Man who is illiterate and who still practices virtue must be extremely pure, a virtuous being. This is the state of Prophets (PBUH) because God had conveyed goodness to them without they acquiring it from men."
