Hi Stephen,

`Because I use the computationalist hypothesis in the cognitive science.`

`It means that relatively to my most probable neighborhood I am determined`

`by a number: my program or godel number if you want. It is the number which`

`make it possible to survive with a digital brain/body, or to survive a`

`reconstitution.`

`I allow them. Since Godel we know that even to study properties of`

`natural numbers we need the whole Cantor Paradise.`

`(Like complex number are indispensable in pure number theory).`

`Note that in set theory cardinality notion are relative. A set can be`

`uncountable as seen in a model, and countable as seen in another model.`

`SPK:`

`BM:`

`I do not explain them away. I explain them and similar terms.`

`It is the *whole* purpose of the UDA and AUDA.`

>possible mathematical equations computed?

`BM:`

`I don't need the hypothesis of "breath". I guess you believe in the need`

`of a material-causal universe computing the solutions of the mathematical`

`equations. But, once you accept a minimal amount of arithmetical realism,`

`all the relevant computations exist arithmetically. Look at Maudlin 1989`

`paper to understand that this is enough, and, even, cannot be ameliorated,`

`once you assume the comp. hyp.`
