Famous quotes containing the words derivative and/or gain:
“Poor John Field!—I trust he does not read this, unless he will improve by it,—thinking to live by some derivative old-country mode in this primitive new country.... With his horizon all his own, yet he a poor man, born to be poor, with his inherited Irish poverty or poor life, his Adam’s grandmother and boggy ways, not to rise in this world, he nor his posterity, till their wading webbed bog-trotting feet get talaria to their heels.”
—Henry David Thoreau (1817–1862)
“The historian must have ... some conception of how men who are not historians behave. Otherwise he will move in a world of the dead. He can only gain that conception through personal experience, and he can only use his personal experiences when he is a genius.”
—E.M. (Edward Morgan)
