Abstract
This paper will discuss the insertion of the Stoic dialectic or, more exactly, the differentiation between the signifier and signified of Stoic language theory, regarding the hermeneutics of words in the Roman Law. The development and expansion of Roman territories allowed the jurists to be in close contact with the Hellenistic philosophical systems, which represented a moment of historic cleavage whose consequences have been reflecting in the contemporary world: the juridical thinking, previously characterized by excessive rigor, started realizing its fallibility, becoming epistemologically more sophisticated and open to interconnecting with knowledge produced by other cultures. The juridical argument of Romans reached its peak of efficacy on the threshold of practicality and rationality inherited from the Greeks, however, without losing its original characteristics of simplicity and concision.
