Famous quotes containing the word objects:

    “Luckless is the country in which the symbols of procreation are the objects of shame, while the agents of destruction are honored! And yet you call that member your pudendum, or shameful part, as if there were anything more glorious than creating life, or anything more atrocious than taking it away.”
    —Savinien Cyrano De Bergerac (1619–1655)
