Passionate Intensity

Turning and turning in the widening gyre
The falcon cannot hear the falconer;
Things fall apart; the centre cannot hold;
Mere anarchy is loosed upon the world,
The blood-dimmed tide is loosed, and everywhere
The ceremony of innocence is drowned;
The best lack all conviction, while the worst
Are full of passionate intensity.

-- William Butler Yeats (1865 - 1939), Irish symbolist poet and dramatist, 1923 Nobel laureate in Literature, The Second Coming (1919)
