neighbouring Benbili, of which A-Io is involved with rivalling Thu. At Ieu Eun University, Shevek struggles with teaching the Urrasti students and is manipulated by the physicists there, who hope that his breakthrough on the General Temporal Theory will allow them to build a faster-than-light ship. A mysterious note asking him to join his 'brothers' spooks Shevek, knowing that fellow like-minded anarchists are on Urras - in the shadows. Eventually, at a dinner party, a drunken Shevek publicly denounces his peers on A-Io, scolding them for their materialistic lives and taking their splendor for granted, before leading to a disastrous sexual encounter that further alienates Shevek from his peers. He has a sobering realisation that the theory he proposes will be capitalised by the Urrasti for potential warfare, not for the benefit of society. Shevek escapes the university, contacts an underground revolutionary group from the note he found, joining in a labor protest in Nio Esseia that is violently suppressed. He flees to the Terran embassy, where he asks them to transmit his theory to all worlds. The Terrans provide him safe passage back to Anarres. Onboard the Davenant (chapter 13) For interplanetary travel to his world, Anarres, Shevek is shown around a Hainish spaceship. Hainish culture is described. A Hainishman named Ketho, who sympathizes with Odonian thought, wants to disembark with Shevek when they land on Anarres. Not knowing if the Anarresti will welcome him back with open arms, Shevek remains content thinking about his family as the spaceship begins to land. Themes Symbolism The ambiguity of Anarres's economic and political situation in relation to Urras is symbolically manifested in the low wall surrounding Anarres's single spaceport. This wall is the only place on the anarchist planet where "No Trespassing!" signs may be seen, and it is where the book begins and ends. The people of Anarres believe that the wall divides a free world from the corrupting influence of an oppressor's ships. On the other hand, the wall could be a prison wall keeping the rest of the planet imprisoned and cut off. Shevek's life attempts to answer this question. In addition to Shevek's journey to answer questions about his society's true level of freedom, the meaning of his theories themselves weave their way into the plot; they not only describe abstract physical concepts, but they also reflect ups and downs of the characters' lives, and the transformation
