Famous quotes containing the words total, derivative and/or exists:
“Computers are good at swift, accurate computation and at storing great masses of information. The brain, on the other hand, is not as efficient a number cruncher and its memory is often highly fallible; a basic inexactness is built into its design. The brain’s strong point is its flexibility. It is unsurpassed at making shrewd guesses and at grasping the total meaning of information presented to it.”
—Jeremy Campbell (b. 1931)
“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 law is a great thing,—because men are poor and weak, and bad. And it is great, because where it exists in its strength, no tyrant can be above it. But between you and me there should be no mention of law as the guide of conduct. Speak to me of honour, and of duty, and of nobility; and tell me what they require of you.”
—Anthony Trollope (1815–1882)
