Description
The present monograph offers a systematic and multi-level analysis of the concept of gauge as auniversal category describing the relationship between representation and invariance. The point of departure is a reconstruction of the semantic field of this concept, encompassing three fundamental dimensions: measure, calibration, and representation. It is demonstrated that gauge isnot merely a measurement operation, but a relational structure that organizes the way in whichquantities are framed, compared, and transformed. The genealogical analysis shows that this concept has deep roots in ancient philosophy. Categories such as μέτρον (measure), λόγος (relation), and ἀναλογία (proportion), developedby Protagoras, Plato, and Aristotle, constitute structural precursors of the modern understandingof gauge as a relation between different representations of the same magnitude.
