If you know the enemy and know yourself, you need not fear the results of a hundred battles.
If we know that our own men are in a condition to attack, but are unaware that the enemy is not open to attack, we have gone only halfway towards victory.
Hence the saying: If you know the enemy and you know yourself your victory will not stand in doubt, if you now Heaven and you know Earth you may make your victory complete.
I have a dream that one day this nation will rise up and live out the true meaning of its creed: "We hold these truths to be self-evident: that all men are created equal."
