Abstract
This text relates the evolution of the author’s posture as a researcher during the realization of his doctoral thesis and its link with the choice of an analytical approach. Incidentally, this narrative has the dimensions of an autobiographical research. This text illustrates how, within the framework of a thesis, the author implemented a slow evolutionary process of his researcher posture thanks to an analytical approach in writing mode. A return to handwritten writing, considered here as an analyst’s “trick of the trade”, allowed the deployment of the thinking necessary for the conceptualization and transformation of his professional and personal « self » through a method of analysis taking place in five steps, from the transcription to the final writing of the report.
