No doubt friction produces light, but light is the agreement of the atoms. Two people having their own ideas and arguing about them can be a stimulus to thought, and then it does not matter so much; but when a person argues for the sake of argument, the argument becomes his game; he has no satisfaction in conciliation. Words provide the means of disagreement and reasons become the fuel for this fire; but wisdom is found where the intelligence is pliable, where it understands all things, even the wrong of the right and the right of the wrong. The soul who arrives at perfect knowledge has risen above right and wrong. He knows them and yet knows not; he can say much and yet what can he say? Then it becomes easy for him to conciliate each and all.
