Ideas

I like this quote:

Education is a life.  That life is sustained on ideas.  Ideas are of spiritual origin, and God has made us so that we get them chiefly as we convey them to one another, whether by word of mouth, written page, Scripture word, musical symphony;  but we must sustain a child's inner life with ideas as we sustain his body with food.  (CM, A Philosophy of Education p. 109)
