Anathem /

Anathem is a speculative fiction novel by Neal Stephenson, published in 2008. Major themes include the many-worlds interpretation of quantum mechanics and the philosophical debate between Platonic realism and formalism. Anathem is set on and around the planet Arbre. Thousands of years prior to the events in the novel, society was on the verge of collapse. Intellectuals entered concents, much like monastic communities but focused on intellectual endeavors rather than religious practice. Here, the avout— intellectuals living under vows and separated from Sæcular society, fraa (derived from Latin frater) for male avout and suur (derived from Latin soros) for female avout — retain extremely limited access to tools and are banned from possessing or operating any advanced technology (at a level beyond paper and pen) and are watched over by the Inquisition, which answers to the outside world (known as the Sæcular Power). The avout are forbidden to communicate with people outside the walls of the concent except during Apert, a 10-day observance held only once every year, decade, century, or millennium, depending on the frequency with which a given group of avout is allowed to interact with
