“A diamond is a piece of coal that stuck to the job”

“It is absurd to say that our country can issue $30,000,000 in bonds and not $30,000,000 in currency. Both are promises to pay; but one promise fattens the usurer (banker), and the other helps the people. If the currency issued by the Government were no good, then the bonds issued would be no good either. It is a terrible situation when the Government, to increase the national wealth, must go into debt and submit to ruinous interest charges at the hands of men who control the fictitious values of gold.”

“I know of over 3,000 ways [that] a light bulb does not work.”

“Mr. Edison worked endlessly on a problem, using the method of elimination. If a person asked him if he were discouraged because so many attempts proved unavailing, he would say, "No, I am not discouraged, because every wrong attempt discarded is another step forward.".”

“A good intention, with a bad approach, often leads to a poor result.”

“This we prescribe, though no physician; Deep malice makes too deep incision; Forget, forgive; conclude and be agreed; Our doctors say this is no month to bleed.”

“So, good night unto you all. Give me your hands, if we be friends, and Robin shall restore amends.”

“My grief lies onward, and my joy behind.”

“O! that a man might know The end of this day's business, ere it come; But it sufficeth that the day will end, And then the end is known.”

“The bitter past, more welcome is the sweet.”

“The machine unmakes the man. Now that the machine is so perfect, the engineer is nobody.”

“Railroad iron is a magician's rod, in its power to evoke the sleeping energies of land and water.”

“Man moves in all modes, by legs of horses, by wings of winds, by steam, by gas of balloon, by electricity, and stands on tiptoe threatening to hunt the eagle in his own element.”

“I do not understand this squeamishness about the use of gas. We have definitely adopted the position at the Peace Conference of arguing in favour of the retention of gas as a permanent method of warfare. It is sheer affectation to lacerate a man with the poisonous fragment of a bursting shell and to boggle at making his eyes water by means of lachrymatory gas.”

“The United States, and other advanced nations, will someday be able to produce instruments of death so terrible the world will be in abject terror of itself and its ability to end civilization.... Such war-making weapons should be developed - but only for purposes of discovery and experimentation”

“I was armed to the teeth with a pitiful little Smith & Wesson's seven-shooter, which carried a ball like a homopathic pill, and it took the whole seven to make a dose for an adult. But I thought it was grand. It appeared to me to be a dangerous weapon. It had only one fault - you could not hit anything with it.”
