Can our revolution mean anything else than the reversion of social and economic control to Her representatives among Womankind, and the resumption of Her worship on the face of the Earth? Do we dare demand less?”
—Jane Alpert (b. 1947)
“It is doubtful whether anyone who has travelled widely has found anywhere in the world regions more ugly than in the human face.”
—Friedrich Nietzsche (1844–1900)
