Yes . "I love my mother" is some knowledge that I know , and is not
part
of a scientific theory. We know reality because we live in the
reality, We do not approximate reality by theories. We directly know
reality because we live within it. Our primary knowledge is
intuitive, historic, direct.. It is _the_ reality.
A theory is a second class of knowledge about a model that
approximate reality, maybe upto a point of an isomorphism with
some-part-of reality, but certainly, not an isomorphism that embraces
the whole reality, because we could never know if we have modelized
the entire reality, nether if this modelization is accurate.
Let us imagine that we have a mathematical model that isomorphic with the whole reality.
Let us say that this model is before you as some computer implementation. The problem of
coordination still remains. To use this model, you need to find out its particular part
and relate it with reality. The model of the whole reality does not do it by itself.
That seems like an impossible hypothesis. Usually when one talks about having a model it
is a model that one created or someone else created and the correspondence with whatever
is modeled is part of the creation of the model. If you were simply presented with a model
of all reality and you didn't know who created this model so that you could ask them how
it corresponded to the thing modeled then you would be just like a scientist faced with
nature and you would proceed by creating a model of the model in terms you understood.
