Famous quotes containing the words earth and/or orbits:

    “I call heaven and earth to witness against you today that I have set before you life and death, blessings and curses. Choose life so that you and your descendants may live...”
    —Bible: Hebrew, Deuteronomy 30:19.

    “To me, however, the question of the times resolved itself into a practical question of the conduct of life. How shall I live? We are incompetent to solve the times. Our geometry cannot span the huge orbits of the prevailing ideas, behold their return, and reconcile their opposition. We can only obey our own polarity.”
    —Ralph Waldo Emerson (1803–1882)
