History Quotes

“Man has existed for about a million years. He has possessed writing for about 6,000 years, agriculture somewhat longer, but perhaps not much longer. Science, as a dominant factor in determining the belief of educated men, has existed for about 300 years; as a source of economic technique, for about 150 years. In this brief period it has proved itself an incredibly powerful revolutionary force. When we consider how recently it has risen to power, we find ourselves forced to believe that we are at the very beginning of its work in transforming human life.”

“Those, who are strongly wedded to what I shall call 'the classical theory', will fluctuate, I expect, between a belief that I am quite wrong and a belief that I am saying nothing new. It is for others to determine if either of these or the third alternative is right.”

“We must contemplate some extremely unpleasant possibilities, just because we want to avoid them and achieve something better. Nobody, however, likes to think about anything unpleasant, even to avoid it. And so the crucial problem of thermonuclear war is frequently dispatched with the label 'War is unthinkable' -- which, translated freely, means we don't want to think about it.”

“We must learn to live together as brothers or perish together as fools.”

“You have to do your own growing no matter how tall your grandfather was.”

“If history repeats itself, and the unexpected always happens, how incapable must Man be of learning from experience.”

“The mind, once stretched by a new idea, never returns to its original dimensions.”

“A man who views the world the same at fifty as he did at twenty has wasted thirty years of his life.”

“I am always ready to learn although I do not always like being taught.”

“The history of science, like the history of all human ideas, is a history of irresponsible dreams, of obstinacy, and of error. But science is one of the very few human activities-perhaps the only one-in which errors are systematically criticized and fairly often, in time, corrected. This is why we can say that, in science, we often learn from our mistakes, and why we can speak clearly and sensibly about making progress there. In most other fields of human endeavour there is change, but rarely progress ... And in most fields we do not even know how to evaluate change.”
