Famous quotes containing the words setting and/or circles:

    “Linnæus, setting out for Lapland, surveys his “comb” and “spare shirt,” “leathern breeches” and “gauze cap to keep off gnats,” with as much complacency as Bonaparte a park of artillery for the Russian campaign. The quiet bravery of the man is admirable.”
    —Henry David Thoreau (1817–1862)

    “And why do you cry, my dear, why do you cry?
    It is all in the whirling circles of time.
    If millions are born millions must die,”
    —Robinson Jeffers (1887–1962)
