Famous quotes containing the word animals:
“The animals that depend on instinct have an inherent knowledge of the laws of economics and of how to apply them; Man, with his powers of reason, has reduced economics to the level of a farce which is at once funnier and more tragic than Tobacco Road.”
—James Thurber (1894–1961)
