"Travel is fatal to prejudice, bigotry and narrow mindedness, and many of our people need it sorely on these accounts. Broad, wholesome, charitable views of men and things can not be acquired by vegetating in one little corner of the earth all one's lifetime."
Mark Twain, The Innocents Abroad, 1869, conclusion
"The gentle reader will never, never know what a consummate ass he can become, until he goes abroad. I speak now, of course, in the supposition that the gentle reader has not been abroad, and therefore is not already a consummate ass."
Mark Twain, The Innocents Abroad, 1869, chap. XXIII
