Famous quotes containing the words animal kingdom, naturally, animal and/or kingdom:
“Certain anthropologists hold that man, having discovered tools, ceased to evolve biologically. Animals, never having discovered them, continue to fashion drills out of their beaks, oars out of their hind feet, wings out of their forefeet, suits of armor out of their hides, levers out of their horns, saws out of their teeth. Whether this be true or not, all authorities agree that man is the tool-using animal. It sets him off from the rest of the animal kingdom as drastically as does speech.”
—Stuart Chase (1888–1985)
“The rulers of the earth are all worth knowing; they suggest moral reflections: and the respect that one naturally has for God’s vice-regents here on earth is greatly increased by acquaintance with them.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
“The most threatened group in human societies as in animal societies is the unmated male: the unmated male is more likely to wind up in prison or in an asylum or dead than his mated counterpart. He is less likely to be promoted at work and he is considered a poor credit risk.”
—Germaine Greer (b. 1939)
“... what a family is without a steward, a ship without a pilot, a flock without a shepherd, a body without a head, the same, I think, is a kingdom without the health and safety of a good monarch.”
—Elizabeth I (1533–1603)
