“As high as mind stands above nature, so high does the state stand above physical life. Man must therefore venerate the state as a secular deity.... The march of God in the world, that is what the State is.”
—Georg Wilhelm Friedrich Hegel (1770–1831)
“That doctrine [of peace at any price] has done more mischief than any I can well recall that have been afloat in this country. It has occasioned more wars than any of the most ruthless conquerors. It has disturbed and nearly destroyed that political equilibrium so necessary to the liberties and the welfare of the world.”
—Benjamin Disraeli (1804–1881)
