In the case of Galileo, the metaphor of the �World-Book� helped to assert, with its own intrusive power, the attempt to codify a new conception of nature and of science. A new vision of the world was affirmed, taking into account the opposition between a direct reading of �the book on nature� and an indirect reading represented by the books of Aristotle. On the one hand, Borges displays the same metaphor used by Galileo to denounce the false transparency of the mechanisms supporting the Galileian cosmos and to represent the ontological doubts derived from it. The perpetual oscillation between reality, fiction and dreams, typical of Borges' writings - from his poetry to his essays; from his tales to his �tales-essays� - emerges from the elusive properties that the (so-called) �Real� assumes when the fundamental principles of the interpretative paradigm come under discussion.
