Sun Tzu said it best:
It is said that if you know your enemies and know yourself, you will not be imperiled in a hundred battles; if you do not know your enemies but do know yourself, you will win one and lose one; if you do not know your enemies nor yourself, you will be imperiled in every single battle.
To be victorious time and again you must know your enemy. And it is a Buddhist saying that you know yourself by seeing yourself as others see you. Only by reading and learning your enemy can you know them and also, by their own statements about you, learn more about yourself, thereby assuring yourself of victory.
Exactly so.
Now, while Nietzche had a point about being careful when learning about evil (”And if you gaze for long into an abyss, the abyss gazes also into you.”), Camus had the right of it. “The evil that is in the world almost always comes of ignorance, and good intentions may do as much harm as malevolence if they lack understanding.”
