Wandering monsters on plateau

I know not whether Laws be right,
Or whether Laws be wrong;
All that we know who lie in gaol
Is that the wall is strong;
And that each day is like a year,
A year whose days are long.

But this I know, that every Law
That men have made for Man,
Since first Man took His brother’s life,
And the sad world began,
But straws the wheat and saves the chaff
With a most evil fan.

This too I know—and wise it were
If each could know the same—
That every prison that men build
Is built with bricks of shame,
And bound with bars lest Christ should see
How men their brothers maim. — Oscar Wilde (The Ballad of Reading Gaol)
