Famous quotes containing the words theory, natural and/or selection:
“The struggle for existence holds as much in the intellectual as in the physical world. A theory is a species of thinking, and its right to exist is coextensive with its power of resisting extinction by its rivals.”
—Thomas Henry Huxley (1825–95)
“I pity the men whose natural pleasures are burthens, and who fly from joy ... as if it was really an evil in itself.... Poor unfortunate creature that he is! as if the causes of anguish in the heart were not enow—but he must fill up the measure, with those of caprice; and not only walk in a vain shadow,—but disquiet himself in vain too.”
—Laurence Sterne (1713–1768)
“It is the highest and most legitimate pride of an Englishman to have the letters M.P. written after his name. No selection from the alphabet, no doctorship, no fellowship, be it of ever so learned or royal a society, no knightship,—not though it be of the Garter,—confers so fair an honour.”
—Anthony Trollope (1815–1882)
