Philip Wylie said this quote

An old Russian proverb . . . Where hangs the smoke of hate burns a fiercer fire called fear.The trick . . . was to keep that fire alive, but to know at the same time it might consume you also. Then the trick was to make the fear invisible in the smokes of hatred. Having accomplished that, you would own men's souls and your power would be absolute, so long as you never allowed men to see that their hate was but fear, and so long as you, afraid, knowing it, hence more shrewd and cautious than the rest, did not become a corpse at the hands of the hating fearful. There, in a nutshell, was the recipe for dictatorship. Over the proletariat. Over the godly believers. Over the heathen. Over all men, even those who imagined they were free and yet could be made to hate.Frighten; then furnish the whipping boys. Then seize.
