There is no assumption needed for that. It is a category error to say
arithmetics turns into a taste. It is also a category error to say that
arithmetic has an internal view. It makes as much sense to say that a
concept has an internal view. Internal view just applies to the only thing
that can have/is a view, namely cosciousness. This is not a belief, this is
just the obvious reality right now. Can you find any number(s) flying around
that has any claim to an internal view right now? The only thing that you
can find is consciousness being conscious of itself (even an person that
consciousness belongs to is absent, the person is just an object in
consciousness).
You abstract so much that you miss the obvious.
