You are mistaken. Please look up 'begging the question'.
It's ok, you made a mistake. Move on.
I am well aware of what begging the question is and I am not begging the question. However, to humor you let us proceed.
wikipedia.org said:
Begging the question (Latin
petitio principii, "assuming the initial point") is a type of
logical fallacy in which a
proposition relies on an implicit
premise within itself to establish the truth of that same proposition
Now let us examine the logic.
We have a bag.
I say to you, "you know friend inside that bag there either is an apple or there is not an apple."
You say, "why that is preposterous. You cannot know what is in that bag."
I say, "you are right, I cannot know 100% of what is in that bag but nonetheless my statement holds. Either inside that bag an apple exists or inside that bag no apple exists."
you say, "Sir you are begging the question"
I say,"no friend I am simply stating a fundamental rule of logic such that
'A is B' and
'A is not B' are mutually exclusive"
