Dear Bruno,

    What I would very much like to understand is why your modelizations only
seem to include the natural numbers. Why do you not seem to allow for the
entire Cantorian hierarchy of ordinals and cardinals? This, of course,
neglects the fundamental problem that some people have, such as myself, with
the use of Platonia to "explain away" quantities such as mass, charge and
angular momentum. What I would like to know, in addition to the above
question, is how do you answer Stephen Hawking's (?) question: "What breaths
fire into the equations"? or my version: How are the solutions to all
possible mathematical equations computed?

Kindest regards,

Stephen
