"[O]ur Sages were enemies of ignorance. They regarded education, intellectual enlightenment, and the acquisition of knowledge as the first of all moral commandments. They viewed the dissemination of intellectual enlightenment among all classes of the population as the prime concern of the nation, and the training of a child's mind as the first and most sacred duty of fatherhood. They considered it a matter of conscience for every Jewish father to see that his child should not remain a boor and am ha'arets; no Jewish child must be allowed to grow up as an ignorant, uneducated person."
