No doubt friction produces light, but light is the agreement of atoms. When one seeks stimulus to thought it does not matter so much if two people have their own ideas and argue about them, but when a person argues for the sake of argument, the argument becomes his game; he finds no satisfaction in conciliation. Words then provide the means of disagreement, reasons become fuel for that fire. Wisdom is there where the intelligence is pliable, when one understands all things: the wrong of the right, and the right of the wrong. The soul who arrives at the perfect knowledge has risen above right and wrong; he knows them and yet he does not know. He can say much, and yet - what can he say? Then it becomes easy for him to conciliate each and all.
