Bulverism II

And now I come to say,
My beloved Bartholomew,
That your Bulverism has one more bout
With my witness, it's true.

For you said, "I presuppose
"That knowledge must have God."
I prove it here, that it must be so
As solid as a rock.

For you presuppose knowledge can exist
Without God, yet I find this quite specious.
Then you chalk up my knowledge
To psychological stems

Of past experience and Freudian totems.
And class, and religion, and family it's true...
Yet, my bigoted rival, how came this knowledge to you?
For if it be based on a presupposition

Why are rich men deluded to think this world a vision?
Truly even this makes me doubt---
Why not you, you scurrilous case of gout? 
And that word, I had not known, had come into my mind

You mental twine, tangled in a mess of lies...
If my word's not given by God
Then how did I this word find?
More importantly, Bartholomew,

Here is the last question I give---
Are you so sure the material world
Is as based as it is?
Rich, genius men do this doubt in thought;

So again I tell you, Blackguard,
How can there be knowledge without God?
