Utopians

Through unclean eyes they see;
In seeing, make the world be.
They seek to change it all,
Saying they have a call:
To fix it, set it right --
Malleable, all in sight.
But could they let us know,
How far they hope to go?
Do we know us so well
That we can always tell
The consequence of deed,
Where thought or act may lead?
Have we such knowledge of
Human nature that we scoff
At old ways and things,
Think of us as kings
And humanity a board
On which our wins are scored?
