I wandered through each chartered street,
Near where the chartered Thames does flow,
A mark in every face I meet,
Marks of weakness, marks of woe.
In every cry of every man,
In every infant’s cry of fear,
In every voice, in every ban,
The mind-forged manacles I hear:
How the chimney-sweeper’s cry
Every blackening church appals,
And the hapless soldier’s sigh
Runs in blood down palace-walls.
But most, through midnight streets I hear
How the youthful harlot’s curse
Blasts the new-born infant’s tear,
And blights with plagues the marriage-hearse.
We think we know our minds but our knowledge is like the experience of a landscape gained through a map. Two dimensional, contour lines only. To know thoroughly we must venture from the plane of the map to the reality of earth and rock and water and stone.
