How do we tell if a book (written by the Universal Library Algorithm (ULA)) of a historical event can be considered a true history of an event? What if that event were in the distant past rather than an event that happened to us yesterday, or in the future? After all, just as the ULA writes books on what you had for breakfast yesterday, it will write books about Alexander the Great's true thoughts (translated into English) and the musical composition of a composer who has not yet been born. There's just as much gibberish and outright fabrication as there is truth in these digital books.

In a prior blog post, *The Coincidence of the Future Being True*, I mentioned *fixed* and *fluid* as terms to keep in mind. Those were great placeholders, but I'll be more specific here. In the short story, *The Library of Babel* by Jorge Luis Borges, it is the hope of the Librarian-narrator that some order does indeed exist in the Library, and perhaps even a periodical order. Their fear was that the Library was maximally disordered, which as it so happens is itself a Grand Order.

How can a reader tell if the one book in their hand of an indefinite number of other possible books on that subject might be the one true history of what's listed within, a true statement said by Thomas Jefferson at breakfast to his mother at the age of six, a true copy of a musical composition by a person who has yet to be born? For that, we have two (subordinate) Great Patterns:

*The Universe As It Is*: natural finite agreement at each 'n'; e.g. 3" sphere; Box #47; John.*The Universal Library Written*: infinite agreement at every 'n'; i.e. "John places 3" sphere in box #47."

We know that at least one finite pattern appears in every Great Pattern, no matter how maximally disordered. In the mathematical philosophic known as the Well-Ordered Principle, we learn that it is true that a rich set of axioms will still be incomplete, *undecided*. For some mathematicians, unless constructed, a number is indiscriminate, undecided, and to their perspective, fiction. So it is with the two Great Patterns above, and the Universal Library Algorithm - *undecided* transitions into *discriminate*.

Here I wish you to keep in the back of your mind my *Postulate of Artificial Inaccessibility* written in a prior post. The two Great Patterns above become The Grand Pattern that is over all patterns.

The convergence of the natural finite agreement at each 'n' with the infinite agreement at every 'n' constructs Decidable Event 'x'.

Decidable Event 'x' (DE*x*) is true *in the periodic universe. *A* fixed *event. All others *fluid *and sometimes in some cyclic universes, somewhen, just fiction through and through*.*

Some readers will recognize that this postulate does not answer the question of how a reader knows if an event in one of the digital books of the ULA can be trusted to be true. This *Postulate of Transition to Grand Convergence* is one step towards understanding how a reader can know the ULA's fiction from its non-fiction.
