Peruzzi Neutrino Telescopes 4 / 18 Al p[adre] Camp[anella]: io stimo più il trovar un vero, benché di cosa leggiera, che ’l disputar lungamente delle massime questioni senza conseguir verità nissuna. To f[ather] Cam[panella]: more I esteem finding a truth, though of a light matter, than disputing long about the greatest questions without attaining any truth. G. Peruzzi Neutrino Telescopes 5 / 18 Heinrich von Kleist: “If all men had green glasses instead of eyes, they would have to judge that the objects they see are green, and they would never be able to decide whether their eye shows them things as they are and whether it does not rather add something that belongs not to the things but to the eye.” G. Peruzzi Neutrino Telescopes 6 / 18 Paul Klee: “Art does not reproduce the visible, it makes visible” and Piet Mondrian: “Not only Science but also Art shows us reality which, at first incomprehensible, gradually reveals itself through the reciprocal relationships intrinsic to things.” G.

Peruzzi Neutrino Telescopes 14 / 18 [Milla, l’Unità del sapere] “in today’s world, it seems, we have lost the taste for those debates that so greatly invested so much energy and attention in the past. While even at the beginning of the century, discussions - for example, on the fundamental value of discontinuity, indeterminacy, causality - interested scientists, philosophers, and men of culture, today only a very few scholars enjoy debating questions of principle.” G. Peruzzi Neutrino Telescopes 15 / 18 Milla and Marcello Cresti G. Peruzzi Neutrino Telescopes 16 / 18 Having lost the empire founded on weapons, another must be built, more solid and more lasting: that of art and science, of culture and peace.
