Obscenity is a moral concept in the verbal arsenal of the Establishment, which abuses the term by applying it, not to expressions of its own morality but to those of another. Pbscene is not the picture of a naked woman who exposes her pubic hair but that of a fully clad general who exposes his medals rewarded in a war of aggression; obscene is not the ritual of the Hippies but the declaration of a high dignitary of the Church that war is necessary for peace.
