If you don't take arithmetic as primitive, I can prove that you

literary philosophers, so I have doubt you can derive addition and
multiplication in the sense I would wait for.
Dear Bruno,
Is this statement correctly written? How is it coherent that I
need to derive from arithmetic that which is already in arithmetic?
Stephen, you are the one telling me that you don't assume the numbers,
so it is normal that I ask you how you derive them form what you assume.
It seems to me that the physical activity of counting is the source
of derivation of arithmetics!
But you have to derive the physical activity first, then.
Of cource we cannot just consider the activity of a single entity
but that of many entities, each counting in their own ways and
developing communication methods between themselves.
Materialism fails since it cannot explain how it is possible for
material things to have representations of things, intensionality,
such as numbers.
yes, even weak materialism. But your point is not valid, unless you
prove it first.
Numbers fail, as a ground of ontology, as they can not transform
themselves and remain the same. Matter is exactly that which can
transform and remain the same!
? (looks like a prose to me).
