The reflection generally focuses on the mode of articulation of sensitivity and thought, through an analysis which will focus on relevance likely to clarify the intellectual postures of G�rard de Nerval in Les Filles du feu and in Les Chim�res (1854). It will precisely be a question of following the sensitive journey of the author who will emerge from his insularity to open up to a transcendent reality in society and in a thought oriented towards the anthropos and the cosmos. The work of elucidation will allow us to dwell on a thought which strives to establish itself as values called to supplant an order in the process of disappearing. The poetic and literary body will thus draw sensitive, material, concrete paths at the end of which there is reason to find a new order, a different cosmogony, with demarcative signs worthy of a global vision of things.
