Famous quotes containing the words dark and/or matter:
“The eye doesn’t see any shapes, it sees only what is differentiated through light and dark or through colors.”
—Johann Wolfgang Von Goethe (1749–1832)
“To get time for civic work, for exercise, for neighborhood projects, reading or meditation, or just plain time to themselves, mothers need to hold out against the fairly recent but surprisingly entrenched myth that “good mothers” are constantly with their children. They will have to speak out at last about the demoralizing effect of spending day after day with small children, no matter how much they love them.”
—Wendy Coppedge Sanford. Ourselves and Our Children, by Boston Women’s Health Book Collective, introduction (1978)
