Famous quotes containing the word inventions:
“I’m afraid for all those who’ll have the bread snatched from their mouths by these machines.... What business has science and capitalism got, bringing all these new inventions into the works, before society has produced a generation educated up to using them!”
—Henrik Ibsen (1828–1906)
“Of all the inventions of man I doubt whether any was more easily accomplished than that of a Heaven.”
—G.C. (Georg Christoph)
“Our inventions are wont to be pretty toys, which distract our attention from serious things. They are but improved means to an unimproved end, an end which it was already but too easy to arrive at; as railroads lead to Boston or New York.”
—Henry David Thoreau (1817–1862)
