“Men are rewarded for learning the practice of violence in virtually any sphere of activity by money, admiration, recognition, respect, and the genuflection of others honoring their sacred and proven masculinity. In male culture, police are heroic and so are outlaws; males who enforce standards are heroic and so are those who violate them.”
—Andrea Dworkin (b. 1946)
“Hast not thy share? On winged feet,
Lo! it rushes thee to meet;
And all that Nature made thy own,
Floating in air or pent in stone,
Will rive the hills and swim the sea,
And, like thy shadow, follow thee.”
—Ralph Waldo Emerson (1803–1882)
