It is currently said that hope goes with youth, and lends to youth its wings of a butterfly; but I fancy that hope is the last gift given to man, and the only gift not given to youth. Youth is pre-emininently the period in which a man can be lyric, fanatical, poetic; but youth is the period in which man can be hopeless. The end of every episode is the end of the world. But the power of hoping through everything, the knowledge that the soul survives its adventures, that great inspiration comes to the middle-aged: God has kept that good wine until now. It is from the backs of the elderly gentlemen that the wings of the butterfly should burst.
