Ouroboros

 A machine which talks about itself,
a statement that predicates itself,
a brain asking origin of itself,
a problem checking its consistency,
a snake evading to eat its own tail -
what commonality all these problems have?

It is the notion of 'itself',
that of its own self,
on whether its essence is 
meaningful or meaningless.

Questions with such binary answers,
can be encoded in a Turing machine.
All answers, always are right or not.
Or their hierarchies are right or not.

Does it ever stop?
Is there a limit after which
determinism prevails?
The answer, when, settles,
and no hierarchy exists?

These rare events seem difficult to find,
but maybe these exist, for example when,
the problem inverts itself as it 
proceeds to predicate itself -
why would self-referencing 
be a sudden, digital process?
A program changing itself,
inverting itself, to not eat its tail
is indeed an awareness that it has.
A consciousness of not falling 
into trap of indeterminacy, puzzles,
or that of "philosophical black hole".
Consciousness (anthropomorphically) emerges off
from such programs and paradoxes,
from the Navier-Stokes problem,
quantum-spectral-gap problem,
quantum gravity, and what not?
