Famous quotes containing the words animals, observed and/or pass:
“The vast results obtained by Science are won by no mystical faculties, by no mental processes other than those which are practiced by every one of us, in the humblest and meanest affairs of life. A detective policeman discovers a burglar from the marks made by his shoe, by a mental process identical with that by which Cuvier restored the extinct animals of Montmartre from fragments of their bones.”
—Thomas Henry Huxley (1825–95)
“One has observed life poorly, if one has not also witnessed the hand that mercifully—kills.”
—Friedrich Nietzsche (1844–1900)
“The style, the house and grounds, and “entertainment” pass for nothing with me. I called on the king, but he made me wait in his hall, and conducted like a man incapacitated for hospitality. There was a man in my neighborhood who lived in a hollow tree. His manners were truly regal. I should have done better had I called on him.”
—Henry David Thoreau (1817–1862)
