Abstract: Valéry intended to propose a "general morphology" in which the poetics of the forms of the spirit would take for model natural forms. The poetic creation, or rather "poietic" is thus thought in the measure of the physiological production. A certain side of structuralism, sometimes assumed by Barthes, also conceives the literary creation by aligning it on the living, separating the destinies of the poetic and the anthropomorphism.
