Comparison of textual analysis applied to two lectures written three years apart by one author: the language satellites.

A comparative textual analysis was carried out on two essays "Thanatol" and "Double Talk," by F. Perrier, which were originally lectures given three years apart by the author, a psychoanalyst. This study involved the use of the ALCESTE software program, a computer-assisted method of discourse analysis. It consists of modelling the distribution of the main words occurring in speeches or texts with a view toward identifying the repetitive language patterns most frequently used by a speaker or writer. This method is described in the first part of the paper. Various types of discourse emerged from analysis along with specific topics. There were three types in the case of Thanatol and four in that of Double Talk. Upon comparing the separate results obtained on each corpus, a pool of significant words observed in the corpus Thanatol was also present in Double Talk. These words were organised into groups called "language satellites" which were dispatched in the various types of discourse. Considering the underlying language structure (the enunciation), they formed another discourse running between the lines of two lectures. This supplementary discourse was recurrent and could be said to label the author and his thoughts. The ALCESTE method brings to light in the textual production of an author a recurrent pattern of discourse which might hold some clues for the analysis of texts and speech and even about the author as evident in his own ideas and thoughts.
