Whoever is born round cannot die square — meaning that a person's fundamental nature cannot be changed, no matter how much time passes or what efforts are made. It is a realistic, if sometimes fatalistic, observation about the limits of change in character and personality.
The proverb reflects a deeply pragmatic view of human nature common in Neapolitan popular philosophy, one shaped by the experience of centuries of social immobility. In a city where birth largely determined fate — whether one was born into the aristocracy of the 'Seggi' (the patrician order of Naples), the merchant class, the artisan guilds, or the mass of the 'popolo minuto' — the idea that a person's essential nature was fixed from birth was not merely pessimistic but empirically grounded. The religious dimension reinforced this: the concept of innate character was connected to the baroque theology of predestination that circulated through the popular Catholicism of Naples, even as the Church officially taught the possibility of redemption and transformation. Eduardo De Filippo's plays often feature characters who attempt to change but are ultimately returned to their original natures by the pressure of circumstances and family — the Neapolitan family, in particular, being a force of tremendous conservative power in fixing individual identity.
The geometric metaphor is elegant and ancient, reflecting both popular wisdom and the influence of classical philosophical ideas about essential natures — particularly the Aristotelian concept of 'essentia' — filtered through the popular culture of the Kingdom of Naples.
