'He has begun to think of happiness as a power of mind, to be cultivated like thought and imagination. Because he has come to the age when he must think of such things, he recalls the times when he has been happy against reason, and for no reason. He recalls the times when has been happy for reasons so small and ephemeral that nobody has learned to charge for them: a bright-colored tiny bird feeding in the top of the tallest sycamore, a bird's song, a wild flower, a butterfly, a briar heavy with ripe berries, the sound of a beloved voice, the touches of loved ones. To miss or refuse the happiness of such free, small, beautiful, and passing things would be dangerous, he thinks. It would dishonour life itself, Heaven itself. It would be ingratitude.'
Wendell Berry, 'The Order of Loving Care' in The Art of Loading Brush, p.216.
