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 lost
The best lack all conviction, while the worst are filled with passionate intensity.

What can be explained is not poetry.

O chestnut-tree, great-rooted blossomer,
Are you the leaf, the blossom or the bole?
O body swayed to music, O brightening glance,
How can we know the dancer from the dance?

Down by the salley gardens my love and I did meet;
She passed the salley gardens with little snow-white feet.
She bid me take love easy, as the leaves grow on the tree;
But I, being young and foolish, with her did not agree.

In a field by the river my love and I did stand,
And on my leaning shoulder she laid her snow-white hand.
She bid me take life easy, as the grass grows on the weirs;
But I was young and foolish, and now am full of tears.

...nothing in them but tittering jeering emptiness.

Who Goes With Fergus?

Who will go drive with Fergus now,
And pierce the deep wood's woven shade,
And dance upon the level shore?
Young man, lift up your russet brow,
And lift your tender eyelids, maid,
And brood on hopes and fear no more.

And no more turn aside and brood
Upon love's bitter mystery;
For Fergus rules the brazen cars,
And rules the shadows of the wood,
And the white breast of the dim sea
And all dishevelled wandering stars.
