Whilst, till the start of this century, many mysteries and enigmas still remained in Ferdinand de Saussure’s biography, recent years have seen the circulation of innumerable authentic documents, related to the life of the founder of la Linguistique générale. It may be observed that the century that has come to an end saw no decrease in the interest that scholars and the cultivated public have shown to the person and the work of F. de Saussure. Quite the opposite, in fact, his posthumous work, CLG, is brought to light and constantly enriched by the publications of the Cercle F. de Saussure, in Geneva, that deal with this abundant documentation. How, for its part, will general semiotics exploit these new documents, so as to carry forward its own research programs?
