Famous quotes containing the words dark and/or matter:
“Alvina felt herself swept ... into a dusky region where men had dark faces and translucent yellow eyes, where all speech was foreign, and life was not her life. It was as if she had fallen from her own world on to another, darker star, where meanings were all changed.”
—D.H. (David Herbert)
“I am afraid that old women are more skeptical in their most secret heart of hearts than any man: they believe in the superficiality of existence as in its essence, and all virtue and profundity is to them merely a veil over this “truth,” a most welcome veil over a pudendum—and so a matter of decency and modesty, and nothing else.”
—Friedrich Nietzsche (1844–1900)
