Humility

...if a man would make his world large, he must be always making himself small. Even the haughty visions, the tall cities, and the toppling pinnacles are the creations of humility. Giants that tread down forests like grass are the creations of humility. Towers that vanish upwards above the loneliest star are the creations of humility. For towers are not tall unless we look up at them; and giants are not giants unless they are larger than we. All this gigantesque imagination, which is, perhaps, the mightiest of the pleasures of man, is at bottom entirely humble. It is impossible without humility to enjoy anything -- even pride.

G.K.Chesterton, from Orthodoxy (1908)
