Famous quotes containing the words derivative and/or works:
“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)
“For thou hast made him a little lower than the angels, and hast
crowned him with glory and honor.
Thou madest him to have dominion over the works of thy hands;”
—Bible: Hebrew Psalm VIII (l. VIII, 5–6)
