perspectiva naturalis into a plane surface, the Renaissance perspectiva artificialis unfurls a new "pictorial" space. To appreciate the impact of quantum theory on determinism and computation issues this paper will adopt a "perspectival" approach: the architecture of the theory, first captured in the "real' three dimensional space, will lead us into a new "imaginary' space. Here the bilateral symmetry coupling any possibility with its negation, sized by "complex probability amplitudes", may dissolve the "ignorance' of classical probabilities as well as the "blindness' of finite mechanical procedures." /> Proof as a path of light - Lupacchini Rossella | sdvig press
