This dissertation s aim objective was to verify the use of literary language on the scientific works Ansichten der Natur and kosmos written by Alexander von Humboldt (1769-1859). The hypothesis emphasized the importance of the aesthetic treatment on the language, resulting in a certain scientific notion and pragmatic. Considering the everlasting preoccupation of Humboldt in never reducing science to its descriptive character nor reducing it to its technically operational character, we´ve perceived an anthropological knowledge predominantly structured,. this allow us to consider, throughout the symbolicaesthetic utilization of scientific matters, many collapses that will be installed between imagination/conscience, magic/science, intuition/concept, mistery/ knowledge, ideal significance/physical appearance, ideal/real, objective/subjective. We then discuss that the conditions of perception and those of experiment transform, the result of the accomplishment. The prerogatives in the Standpunkt of cosmovision and other ways of mediation, like traveling , the exit and the return to oneself, preserve the sensation of totality, in a world growing in disintegration. In conclusion, Humboldt´s science being language and being preserved in its form from its moral effects reveals the possibility of reintegration of Nature and spirit, however it doesn´t change them into an indissoluble unity. Considered as poetic Science, and due to the harmony that it brings forth, Humboldt´s knowledge gives to the empirical a starting point, a direction that will precisely signify an idealistic/ transcending recover over of the world.
