Famous quotes containing the word modern:
“I do not approve the extermination of the enemy; the policy of exterminating or, as it is barbarously said, liquidating enemies, is one of the most alarming developments of modern war and peace, from the point of view of those who desire the survival of culture. One needs the enemy.”
—T.S. (Thomas Stearns)
