"You know nothing for sure...except the fact..." - Quote by John F Kennedy

“We are confronted primarily with a moral issue... whether all Americans are to be afforded equal rights and equal opportunities, whether we are going to treat our fellow Americans as we want to be treated.”

“A man does what he must - in spite of personal consequences, in spite of obstacles and dangers and pressures - and that is the basis of all human morality.”

“Aggressive conduct, if allowed to go unchecked and unchallenged, ultimately leads to war.”

“What refuge is there for the victim who is oppressed with the feeling that there are a thousand new books he ought to read, while life is only long enough for him to attempt to read a hundred?”

“Wisdom is knowing what you don't know.”

“Everyone holds a piece of the truth.”

“Moral certainty is always a sign of cultural inferiority. The more uncivilized the man, the surer he is that he knows precisely what is right and what is wrong.”

“Feed and strengthen your body. Fear is physical. When you lift weights or go for a sprint, that energy flows back into your body and restores you to certainty.”

“If you develop the absolute sense of certainty that powerful beliefs provide, then you can get yourself to accomplish virtually anything, including those things that other people are certain are impossible.”
