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)
“Prohibition will work great injury to the cause of temperance. It is a species of intemperance within itself, for it goes beyond the bounds of reason in that it attempts to control a man’s appetite by legislation, and makes a crime out of things that are not crimes. A Prohibition law strikes a blow at the very principles upon which our government was founded.”
—Abraham Lincoln (1809–1865)
