A proof that the comp-physics does not allow quantum computation. For example the "intelligible matter" or the "sensible matter" could have given formally modal systems collapsing into classical logic, in which it is known (as Stephen has said many times) we can not embed quantum logic. Imagine just that the material modalities give Newtonian Mechanics. It can be proved that newtonian (relativistic or not) mechanics cannot justify real (relative) time quantum computations. > > By the way, I've finished reading Plato's Theaetetus, Protogoras, > Parmenides, and Sophist and I am working on Aristotle's Metaphysics. > So then perhaps I will be ready for Plotinus! (?) Don't forget the intriguing Timaeus! ;) (I think Plotinus will help you for those older text; but don't take his *illustration* too seriously ... , just look at the validity of his reasoning). You can also read the little book on Plotinus by O'Meara (very good); ref in my theses.
