True,' I said, amazed. Until then I had thought each book spoke of the things, human or devine, that lie outside books. Now I realized that not infrequently books speak of books: it is as if they spoke among themselves. In the light of this reflection, the library seemed all the more disturbing to me. It was then a place of a long, centuries-old murmuring, an imperceptible dialogue between one parchment and another, a living thing, a receptacle of powers not to be ruled by a human mind, a treasure of secrets emanated by many minds, surviving the death of those who had produced them or had been their conveyors.

I am not saying that philosophies, since they are speculative, speak of the nonexistent. When they say 'subject' or 'class struggle' or 'dialectics', they always point to something that should have been defined and posited in some way. Philosophies can be judged, at most, on the grounds of the perspicacity with which they decide that something is worthy of becoming the starting point for a global explanatory hypothesis. Thus I do not think that the sign (or any other suitable object for a general semiotics) is a mere figment.
