To destroy a man is difficult, almost as difficult as to create one: it has not been easy, nor quick, but you Germans have succeeded. Here we are, docile under your gaze; from our side you have nothing more to fear; no acts of violence, no words of defiance, not even a look of judgment.

Monsters exist, but they are too few in numbers to be truly dangerous. More dangerous are…the functionaries ready to believe and act without asking questions.

Did chemistry theorems exist? No: therefore you had to go further, not be satisfied with the quia, go back to the origins, to mathematics and physics. The origins of chemistry were ignoble, or at least equivocal: the dens of the alchemists, their abominable hodgepodge of ideas and language, their confessed interest in gold, their Levantine swindles typical of charlatans and magicians; instead, at the origin of physics lay the strenuous clarity of the West-Archimedes and Euclid.

It is enough not to see, not to listen, not to act.

The living are more demanding; the dead can wait.
