From The Prelude to the Lyrical Ballads

As the black storm upon the mountain top
Sets off the sunbeam in the valley, so
That huge fermenting mass of humankind
Serves as a solemn background, or relief,
To single forms and objects, whence they draw,
For feeling and contemplative regard,
More than inherent liveliness and power.
How oft, amid those overflowing streets,
Have I gone forward with the crowd, and said
Unto myself, `The face of every one
That passes by me is a mystery!'
Thus have I looked, nor ceased to look, oppressed
By thoughts of what and whither, when and how,
Until the shapes before my eyes became
A second-sight procession, such as glides
Over still mountains, or appears in dreams;
And once, far-travelled in such mood, beyond
The reach of common indication, lost
Amid the moving pageant, I was smitten
Abruptly, with the view (a sight not rare)
Of a blind Beggar, who, with upright face,
Stood, propped against a wall, upon his chest
Wearing a written paper, to explain
His story, whence he came, and who he was.
Caught by the spectacle my mind turned round
As with the might of waters; an apt type
This label seemed of the utmost we can know,
Both of ourselves and of the universe;
And, on the shape of that unmoving man,
His fixed face and sightless eyes, I looked,
As if admonished from another world.
