“I have yet to see any problem, however complicated, which, when you looked at it in the right way, did not become still more complicated.”

“Don't get involved in partial problems, but always take flight to where there is a free view over the whole single great problem, even if this view is still not a clear one.”

“But Jesus, when you don't have any money, the problem is food. When you have money, it's sex. When you have both, it's health, you worry about getting ruptured or something. If everything is simply jake then you're frightened of death.”

“The best way out is always through.”

“Avoiding a problem doesn't solve it.”

“A good scientist is a person with original ideas. A good engineer is a person who makes a design that works with as few original ideas as possible. There are no prima donnas in engineering.”

“A good cause can become bad if we fight for it with means that are indiscriminately murderous. A bad cause can become good if enough people fight for it in a spirit of comradeship and self-sacrifice. In the end it is how you fight, as much as why you fight, that makes your cause good or bad.”

“If we had a reliable way to label our toys good and bad, it would be easy to regulate technology wisely. But we can rarely see far enough ahead to know which road leads to damnation. Whoever concerns himself with big technology, either to push it forward or to stop it, is gambling in human lives.”

“It's better to get mugged than to live a life of fear.”

“The question that will decide our destiny is not whether we shall expand into space. It is: shall we be one species or a million? A million species will not exhaust the ecological niches that are awaiting the arrival of intelligence.”
