I saw a man unreasoning
Yet sure that he was right,
Unable to admit that some
Possess a different sight.

I threw a thought out to the world;
A different way of seeing,
And to my lintel they converged
To condemn my very being.

Like vultures on a carcass
They picked the bones to see
If, for some flaw, they could reject
The responsibility to see.
