“Defending yourself is not the same as offending your enemy. Watch what you say.”

“I disapprove of what you say, but I will defend to the death your right to say it.”

“Misdirection is the key to survival, never attack what your enemy defends, never behave as your enemy expects, and never reveal your true strength, if knowledge is power then to be unknown is to be unconquerable.”

“Know the enemy and know yourself; in a hundred battles you will never be in peril. When you are ignorant of the enemy, but know yourself, your chances of winning or losing are equal. If ignorant both of your enemy and yourself, you are certain in every battle to be in peril.”

“Hence the saying: If you know the enemy and know yourself, you need not fear the result of a hundred battles. If you know yourself but not the enemy, for every victory gained you will also suffer a defeat. If you know neither the enemy nor yourself, you will succumb in every battle.”

“They say you can know a man by his enemies, Dresden." He smiled, and laughter lurked beneath his next words, never quite surfacing. "You defy beings that should cow you into silence. You resist forces that are inevitable for no more reason than that you believe they should be resisted. You bow your head to neither demons nor angels, and you put yourself in harm's way to defend those who cannot defend themselves." He nodded slowly. "I think I like you.”
