L'idea che il numero esprima l'essenza della realtà, così come la concezione delle matematiche quali discipline teoretiche sono tradizionalmente attribuite a Pitagora. In realtà, è difficile stabilire cosa risalga al suo insegnamento e cosa invece agli sviluppi successivi. Di sicuro l'interesse per il numero e le sue proprietà caratterizza già il nucleo più antico della scuola. In questa fase, aritmetica e geometria sono strettamente intrecciate l'un l'altra: solo la scoperta dell'irrazionale porta a distinguere lo studio del discreto numerico da quello del continuo spaziale.

Abstract
The idea that reality is a number, as well as the conception of mathematics as theoretical disciplines are traditionally attributed to Pythagoras. In fact, it is difficult to determine what goes back to his teaching and what should belong to the later developments. Certainly the interest in the number and its properties characterizes already the most ancient nucleus of the school. At this stage, the arithmetic and geometry are closely related to one another: only the discovery of the irrational leads to distinguish the study of discrete numeric from that of the continuous space.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
