"It must be confessed that the inventors..." - Quote by Voltaire

“When we cannot use the compass of mathematics or the torch of experience...it is certain we cannot take a single step forward.”

“I hold firmly to my original views. After all I am a philosopher.”

“Thought depends absolutely on the stomach, but in spite of that, those who have the best stomachs are not the best thinkers.”

“Nothing can have value without being an object of utility.”

“If what you want to tell me is neither True nor Good nor even Useful, why tell it to me at all”

“I believe that there never was a creator of a philosophical system who did not confess at the end of his life that he had wasted his time. It must be admitted that the inventors of the mechanical arts have been much more useful to men that the inventors of syllogisms. He who imagined a ship towers considerably above him who imagined innate ideas.”

“Anything that won't sell, I don't want to invent. Its sale is proof of utility, and utility is success.”

“It is only the unimaginative who ever invents. The true artist is known by the use he makes of what he annexes.”

“Invention is the talent of youth, as judgment is of age.”
