The splendid discontent of God
    With chaos, made the world,
Set suns in place, and filled all space
    With stars that shone and whirled.

If apes had been content with tails,
    No thing of higher shape
Had come to birth! the king of earth
    To-day would be an ape.

And from the discontent of man
    The world's best progress springs.
Then feed the flame (from God it came)
    Until you mount on wings.
