"Who are the inventors of Tlön? The plural is inevitable, because the hypothesis of a lone inventor — an infinite Leibniz laboring away darkly and modestly — has been unanimously discounted. It is conjectured that this brave new world is the work of a secret society of astronomers, biologists, engineers, metaphysicians, poets, chemists, algebraists, moralists, painters, geometers... directed by an obscure man of genius. Individuals mastering these diverse disciplines are abundant, but not so those capable of inventiveness and less so those capable of subordinating that inventiveness to a rigorous and systematic plan. This plan is so vast that each writer's contribution is infinitesimal. At first it was believed that Tlön was a mere chaos, and irresponsible license of the imagination; now it is known that it is a cosmos and that the intimate laws which govern it have been formulated, at least provisionally. Let it suffice for me to recall that the apparent contradictions of the Eleventh Volume are the fundamental basis for the proof that the other volumes exist, so lucid and exact is the order observed in it."

“There are people who barely feel poetry, and they are generally dedicated to teaching it.”

“It is clear that there is no classification of the Universe that is not arbitrary and full of conjectures. The reason for this is very simple: we do not know what kind of thing the universe is.”

“Do you want to see what human eyes have never seen? Look at the moon. Do you want to hear what ears have never heard? Listen to the bird's cry. Do you want to touch what hands have never touched? Touch the earth. Verily I say that God is about to create the world.”

“I thought of a labyrinth of labyrinths, of one sinuous spreading labyrinth that would encompass the past and the future and in some way involve the stars.”

“Villari took no notice of them because the idea of a coincidence between art and reality was alien to him. Unlike people who read novels, he never saw himself as a character in a work of art.”

“Literature is not exhaustible, for the sufficient and simple reason that a single book is not. A book is not an isolated entity: it is a narration, an axis of innumerable narrations. One literature differs from another, either before or after it, not so much because of the text as for the manner in which it is read.”
