—Herman Melville (1819–1891)
“This state is full of these log cabin Abe Lincolns with price tags on ‘em. The louder he yells, the higher his price.”
—Robert Rossen (1908–1966)
“A nation fights well in proportion to the amount of men and materials it has. And the other equation is that the individual soldier in that army is a more effective soldier the poorer his standard of living has been in the past.”
