When one reads a work of the mind, which was originally a lecture given in an audience and which becomes a book, one always takes serious measures so that the traces of orality cannot show through. For this reason, we have made it our duty to say so, so that this remark, which the reader might detect in some places and which might have slipped in inadvertently, cannot be considered as an element that could diminish the value of the present writing. The latter always keeps its intrinsic value that will catch you. This manual is primarily intended for researchers in literature in general, students who have embraced languages and literature in particular, and those in the information and communication sciences.
