Famous quotes containing the words drug, reference and/or standard:
“Most people aren’t appreciated enough, and the bravest things we do in our lives are usually known only to ourselves. No one throws ticker tape on the man who chose to be faithful to his wife, on the lawyer who didn’t take the drug money, or the daughter who held her tongue again and again. All this anonymous heroism.”
—Peggy Noonan (b. 1950)
“If Hitler invaded hell I would make at least a favourable reference to the devil in the House of Commons.”
—Winston Churchill (1874–1965)
“If the Revolution has the right to destroy bridges and art monuments whenever necessary, it will stop still less from laying its hand on any tendency in art which, no matter how great its achievement in form, threatens to disintegrate the revolutionary environment or to arouse the internal forces of the Revolution, that is, the proletariat, the peasantry and the intelligentsia, to a hostile opposition to one another. Our standard is, clearly, political, imperative and intolerant.”
—Leon Trotsky (1879–1940)
