"It is not a struggle merely of economic theories, or forms of government or of military power. At issue is the true nature of man. Either man is the creature whom the psalmist described as a little lower than the angels ... or man is a soulless, animated machine to be enslaved, used and consumed by the state for its own glorification. It is, therefore, a struggle which goes to the roots of the human spirit, and its shadow falls across the long sweep of man's destiny."
