If you don't take arithmetic as primitive, I can prove that you cannot derive both addition and multiplication, nor the existence of computer. Then everything around me does not make sense. If you believe you can derive them, then do it. But you proceed like a 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.

Dear Bruno,

```
I will differ to David Chalmers work to demonstrate a thorough demolition of materialism. I see numbers are an aspect of mental content and not independently existing entities, so we have an irreconcilable difference in our thinking.
```
```
Then comp is meaningless. Even Church thesis is meaningless. Most papers you referred to becomes meaningless.
```

```

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.

```

```
I no longer see the utility of trying to prove the existence of the content of 1p experience.
```
```
I was talking of deriving physics. We accept content of experience in comp, but then we can recover it from the numbers complex behavior when looking at themselves. Then physics is or should be explained from that, as UDA explains.
```

```
I experience it and can bet that you do as well. That is my theory of a physical world and its activity in a nutshell.
```
That's the part where we agree.

```
I explain experience from computer science, and it seems you disagree with this, but then I don't understand why you keep defending comp as it is clear it does not fit with your theory.
```

```
```

```
```
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.
```
What benefit comes from this "proof"?
```
```
To get an explanation.

```
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).
```
```
OK...
