Silence After the Clamors

This, therefore, is the true and proper investigation of nature through art, to which the caput naturae head of nature gives testimony. Furthermore, one should by no means be angered, as was Plato (who devoted himself solely to theoria theory and speculation), that geometry was brought from said speculation and rebus incorporeis incorporeal things to corporeis corporeal things and objects graspable by human senses by Eudoxus of Cnidus and his teacher Archytas of Tarentum. This Archytas fashioned a dove that flew in the air through his art, thus confirming his art with an excellent example. Eudoxus was the first to bring to light and teach the rationes reasons and demonstrationes demonstrations of geometry through instruments. Instead, we should recognize with a grateful heart that the fruit shows itself after the blossom, the daughter from the mother, that is, the practic practical application testifies to the theori theory. Where this does not happen, the arts are no longer arts, but are like sophistica sophistry.
