Abstract

The thesis is preceded by an introduction, in which the Morinian systemic and organizational conception is expounded , as well as the new intelligibility implied therein, which demands the reintroduction of the self, which is no other than the paradigm of complexity, the same that will appear in action throughout the investigation. ;The investigation is constructed in three parts. In the first, it is shown how the concept of self is biological, and hence scientific: being-self is the proper and specific quality of living beings and life, the life of life. The biological self is a complex concept, the concept made of concepts , and moreover it is a paradigm, as far as its presence is necessary in any notion or theory about life. ;In the second part it is shown how being-self is the "logically primitive" notion needed to conceive of the human being. One also sees the hypercomplex character of the human self, which is due precisely to its multiple roots and dependencies, simultaneously biological/psychological/sociological/noological. Likewise one sees how from these dependencies paradoxically emerges uncertain individuality and individual autonomy and also consciousness, a supreme and fragile instance from which the human being simultaneously sapiens/demens, is to establish his never-ending and uncertain "struggle against error", which enables him to progress in knowledge at the same time as progressing in the knowledge of his ignorance. ;Finally, in the third part, are shown the consequences that the condition of self, proper to the human being, and the hypercomplex and uncertain character of the same, have for action . ;The investigation concludes with an analysis of the significance of what we call the Morinian credo and of the meaning that the "wager" in favour of life and Humanity is to have.
