"irrefutable"

"irrefutable" is the candy coat
we paint upon the things we've proved,
reducing them to math and sign
where they all work so perfectly.
Since we're behooved to make
so sure. Except the things aren't math
or sign. There's more in them
than figured out. When scant details
and unincluded parts can slink
and slim their ways inside,
it breaks. The truth comes out.
The shell cracks wide, like rhyming "rhyme"
with "rhyme" - we find we've only
shown how vast our lack of knowledge
is. What makes the thing the thing
is blown away, with lightning blast. Except
some hard held bits remain! Still valid now,
as we inspect. We'll use them to redraw
the frame and cast the shape we recognize,
with parts impartially correct.
We'll redraw math and sign
in tighter grip and grasp
upon what's real. We've
checked. Replace
the certainty we found
with certainty we'll find,
and never face the facts
that we don't know, the fact
we don't know what we're
leaving out.

Since we are blind,

This is the only way we have
to go. The only thing
that we don't know
is doubt.
