Famous quotes containing the words celestial and/or bodies:
“When the spirit brings light into our minds, it dispels darkness. We see it, as we do that of the sun at noon, and need not the twilight of reason to show it us. This light from heaven is strong, clear, and pure carries its own demonstration with it; and we may as naturally take a glow-worm to assist us to discover the sun, as to examine the celestial ray by our dim candle, reason.”
—John Locke (16321704)
“Many things about our bodies would not seem to us so filthy and obscene if we did not have the idea of nobility in our heads.”
—G.C. (Georg Christoph)
