Famous quotes containing the words extinct and/or species:
“One realises, with horror, that the race of men is almost extinct in Europe. Only Christ-like heroes and woman-worshipping Don Juans, and rabid equality-mongrels. The old, hardy, indomitable male is gone.”
—D.H. (David Herbert)
“Books, gentlemen, are a species of men, and introduced to them you circulate in the “very best society” that this world can furnish, without the intolerable infliction of “dressing” to go into it. In your shabbiest coat and cosiest slippers you may socially chat even with the fastidious Earl of Chesterfield, and lounging under a tree enjoy the divinest intimacy with my late lord of Verulam.”
—Herman Melville (1819–1891)
