Who said “A good scientist is a person with original ideas. A good engineer is a person who makes…”?

“For 'Tis the sport to have the engineer hoisted with his own petard.”

“My advice is to look out for engineers. They begin with sewing machines and end up with nuclear bombs.”

“To define it rudely but not ineptly, engineering is the art of doing that well with one dollar, which any bungler can do with two after a fashion.”

“Hedonic Engineering -- The human nervous system studying and improving itself: intelligence studying and improving intelligence. Why be depressed, dumb, and agitated when you can be happy, smart, and tranquil?”

“There is a great satisfaction in building good tools for other people to use.”

“It is characteristic of all deep human problems that they are not to be approached without some humor and some bewilderment.”

“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.”
