It is only the enlightened ruler and the wise general who will use the highest intelligence of the army for the purposes of spying, and thereby they achieve great results.
What is education? Properly speaking, there is no such thing as education. Education is simply the soul of a society as it passes from one generation to another. Whatever the soul is like, it will have to be passed on somehow, consciously or unconsciously, and that transition may be called education. ...
