A rational person believes a finite number of propositions;Rational does not imply perfection in thought. For a being to achieve
that is, he believes all of them they are true. (if he thought
any one was false, he'd disbelieve it)
A rational person also disbelieves in his own perfection.
He expects to be wrong occasionally.
This implies that one of the list of the propositions
referenced above, must be false. And he's aware of this
implication. Which means he believes he believes
something false.
Is this inconsistent? Is he rational? Explain.

You seem, above, to float a definition of a rational person then
move on to ask a question given your definition.
If the definition was of a abstract system (e.g., something in the class
of Turing machines) you could ask if such a system could be defined, not whether it is consistent.
