Probably not.
In fact, you probably have no idea what the Hylaean Theoric World even is, let alone a Teglon. Both are important, however, in Arbre, the world of Neal Stephenson's Anathem.
The novel is set up as an almost journal-like account of the life of Fraa Erasmas, an avout in the Concent of Saunt Edhar. None of the terms are probably familiar to you, but may remind you of terms that are. Here's a hint: translated into Earth-English, the description of Erasmas may be something like Friar Erasmas, a devout in the Convent of Saint Edhar.Although Erasmas is decidedly not religious: concents are places not of religious devotion, but a devotion of a different sort. Avout in concents like Saunt Edhar's spend their lives studying logic, theory, and other sciences while remaining separate from the Saecular world, emerging only at Apert.
While I could go on and on about the world of Anathem, it would likely take up the same whopping 937 pages as Stephenson's novel, so I will refrain and instead move on to the most important aspect of this novel: the Hylaean Theoric World and Complex Protism.
The Hylaean Theoric World is what sets the world of the theoric avout apart from the world of the religious Bazians and Deolaters. It stems from an ancient story about a man who looked into the sky and saw an isoceles triangle. The Deolaters thought it a vision of a higher world, a deity, while the Hylaeans believed that it was a vision of an "ideal" triangle: not the representation humans create, but the actual ideal version.
This line of thinking bred the avout.
But this idea is not the only thing that drives the plot of Anathem. There is also Protism: the thought that information flows from the Hylaean Theoric World, or from the ideal, to Arbre, or to the less-than-ideal. Complex Protism, Erasmas learns, includes other worlds beyond the basic HTW and Arbre. Complex Protism eventually becomes incredibly important in the events that unfold in the novel - but I won't spoil the surprise.Other things in Anathem are also important - for example, Erasmas' relationship to his mentor, Fraa Orolo, shapes much of the novel. His friends are also important not only to Erasmas' development as a character, but also to the development of the plot.
Still, the sheer length of Anathem - 890 pages of plot, plus 47 pages of Glossary and Calcas - may be daunting to the average reader, many of whom struggled through the relatively short and simple Harry Potter novels.
My conclusion? The dedicated reader of science fiction, philosophy, or logic will find Anathem an intense read that stretches the mind and the beliefs of anyone who might pick it up.
