"The error in the disconnection of assumptions: the paradox of a symptomatology of error, between prophetic sign and unconscious semiotic gestures"As such, the relationship that its system of gestural signs maintains with reality raises the question: is the error a model of its own local configuration, capable of exemplifying a particular form of life or a model to symbolize beyond its initial anchoring, and integrate institutions of meaning which frame its symptoms and claim to be able to control them, to channel them entirely into categories prior to its enunciation?Once we pose the problem like this, we glimpse the theoretical friction of such an opposition : the error cannot be described under the exclusive semiotic regency of a model of or a model for, and its varied forms of life (failure, bug, sporting error, impasse, wandering, imperfection, etc.) even overflow with a dialectical conception. Indeed, the gestures of error, most often daily and unconscious, demonstrate the complexity of an emerging enunciation, provided with a prior and unstated semiotic depth (Basso Fossali 2017, chap. 6.4, pp.535-556), and a problematic responsibility in the posterity of their enunciation.Thus, our intervention will aim to emphasize three aspects : (i) How to describe this complexity with specifical tools of Language Sciences?(ii) To what extent does this semiotics framing re-examine the relationship between error, sign and reality?And (iii) In what way can we protect these gestures from overinterpretation ?
