Famous quotes containing the word travel:

    “There is the grand truth about Nathaniel Hawthorne. He says NO! in thunder; but the Devil himself cannot make him say yes. For all men who say yes, lie; and all men who say no,—why, they are in the happy condition of judicious, unincumbered travellers in Europe; they cross the frontiers into Eternity with nothing but a carpet-bag,—that is to say, the Ego. Whereas those yes-gentry, they travel with heaps of baggage, and, damn them! they will never get through the Custom House.”
    —Herman Melville (1819–1891)

    “Two roads diverged in a yellow wood,
    And sorry I could not travel both
    And be one traveler, long I stood
    And looked down one as far as I could”
    —Robert Frost (1874–1963)

    “So soon did we, wayfarers, begin to learn that man’s life is rounded with the same few facts, the same simple relations everywhere, and it is vain to travel to find it new.”
    —Henry David Thoreau (1817–1862)
