"How much larger your life would be if your self could become smaller in it; if you could really look at other men [and women] with common curiosity and pleasure. You would break out of this tiny and tawdry theatre in which your own little plot is always being played, and you would find yourself under a freer sky, and in a street full of splendid strangers." (G. K. Chesterton, Orthodoxy, Garden City, N.Y.: Doubleday Image Books, 1959, pp. 20,21.)
