Famous quotes containing the word scale:
“I have spent all my life under a Communist regime, and I will tell you that a society without any objective legal scale is a terrible one indeed. But a society with no other scale but the legal one is not quite worthy of man either.”
—Alexander Solzhenitsyn (b. 1918)
