When considering virtue the natural tendency is to disregard the laws which govern human nature. The mystic therefore does not take the point of view of some preachers who urge and impose upon all those who come to them that they should be good, that they should be kind, and that they should be just. A mystic recognizes that man's first response is to react in accordance with what strikes him. We already see this tendency in a child. When we smile at the child it will laugh, but if we show it a hand as if we were going to strike it the child will do the same unless it is afraid; at least its desire would be the same, it would want to hit back. Therefore there is nothing to be surprised at if Moses stood before the multitude and told them, "An eye for an eye, and a tooth for a tooth." What else could he have said to them? "Be ye kind and saintly and most loving'? Would they have listened to that?
