English poem
Wise Man
by W. B. Yeats
Were it but true 'twould alter everything Until the stream of the world had changed its course, And that and all our thoughts had run Into some cloudy thunderous spring They dream to be its source-- Aye, to some frenzy of the mind; And all that we have done would be undone, Our speculation but as the wind.
[A pause.
I have dreamed it twice.
