Acknowledging is giving life to something. If you do not take notice of things, they die because you have not given them life. By noticing them you give life to things which may not be profitable to you. There is the simple one, the clever one, and the wise one. The simple one does not see into human nature; the clever one sees it and what he sees he says; the wise one sees and does not say anything, and it is that which makes him wise.
