If the Schrodingerwave function for a particle is a odd function, that is F(x) = -F(-x), then it's a fermion and the probability of 2 fermions occupyingthe same quantum state is zero, in other words it obeys the PauliExclusion Principle and is the reason that the ground beneath yourfeet, which is made of fermions, is solid and you don't sink to thecenter of the Earth.If the Schrodinger wave function for a particle is a even function,that is F(x) = F(-x), then it's a boson and it can ignore the PauliExclusion Principle and is the reason light rays, made of bosons,don't scramble each other when they collide at right angles, lightparticles can occupy the same quantum state and thus can passthrough each other and be completely unaffected; it's the reasonthe light rays that enter our eye are not a hopeless chaotic jumbleof information randomized by a astronomical large number ofcollisions with other photons.

`Yes, that is what I was alluding to by mentionning "à-la-Feynman", as`

Yep, I knew that. I thought for a moment that Bruno claimed toderive something like that from comp, but it turns out that all heclaims is that if comp is the theory-of-eveything then it mustpredict everything.

`Nowhere is Comp assumed to be the theory of everything. It is just the`

`assumption that "I" am a digital machine (mechanism), to put it shortly.`

`Then we derive from that assumption that arithmetic is a theory of`

`everything, as good as any other (basically a first order`

`specification of a Turing universal system), and then the derivation`

`is constructive.`

It is quite different from what you say.

`You did understood the seven steps (not clear for the step 8), but now`

`you seem to have forgotten the points, or even the goal.`

`The goal is not to replace physics as a science, but to get a correct`

`picture of the possible reality, and the possible fundamental science,`

`once we assume computationalism without putting first person and`

`consciousness under the carpet.`

Main result: Aristotle theology can't work. Plato's theology still work.
