“An educated mind is nothing but the God-given mind of a child after his parents’ and his grandparents’ generation have got through molding it. We can’t help teaching you; you will ask that of us; but we are prone to teach you what we know, and I am going, now and again, to warn you:Remember we really don’t know anything. Keep your baby eyes (which are the eyes of genius) on what we don’t know. That is your playground, bare and graveled, safe and unbreakable.”
