We would do a disservice to those warriors of justice -- Tubman, and D — Barack Obama

"In an interview with Steve Kroft of 60 Minutes, the day before announcing his candidacy for President:"

"All of us must recognise that education and innovation will be the currency of the 21st Century."

"Let me just make this point, John...Were not campaigning anymore. The elections over."

"By 2014, the war in Afghanistan will be over."

"Only you can make sure the democracy you inherit is as good as we know it can be. But it requires your dedicated, informed, and engaged citizenship. This citizenship is a harder, higher road to take. But it leads to a better place. It is how we built this country – together. It is the question President Kennedy posed to the nation at his inauguration; the dream that Dr. King invoked. It does not promise easy success or immediate progress. But it has led to success, and it has led to progress. That brings me to the second thing I ask of you – I ask you to persevere."

"Let me be absolutely clear: Iran is a grave threat."

"In the life of the mass-order, the culture of the generality tends to conform to the demands of the average human being. Spirituality decays through being diffused among the masses when knowledge is impoverished in every possible way by rationalisation until it becomes accessible to the crude understanding of all."

"I say this to you because we Spaniards are a forgetful people, because we are used to living for the moment, because we do not look back, because we do not know how to see the chain of heroes, because we do not contemplate the sum of sacrifices."

"Sharon Tate was my best friend. Once, we were roommates. She introduced me to my husband. She was the godmother to my baby daughter who is named for her. In the six years time that I knew her, she never said an unkind word about anyone."

"Long time to see. (VS: Tapion)"

"Most mathematicians prove what they can, von Neumann proves what he wants." Once in a discussion about the rapid growth of mathematics in modern times, von Neumann was heard to remark that whereas thirty years ago a mathematician could grasp all of mathematics, that is impossible today. Someone asked him: "What percentage of all mathematics might a person aspire to understand today?" Von Neumann went into one of his five-second thinking trances, and said: "About 28 percent."

"Children must be free to think in all directions irrespective of the peculiar ideas of parents who often seal their childrens minds with preconceived prejudices and false concepts of past generations. Unless we are very careful, very careful indeed, and very conscientious, there is still great danger that our children may turn out to be the same kind of people we are."
