In the world Le Guin created everything is informed by a principle of duality. There are complementing nations of Karhide and Orgoreyn sharing a continent, both male and female are residing in each individual, there are even lines of a poem evidencing it: "Light is the left hand of darkness and darkness the right hand of light. Two are one, life and death, lying together like lovers in kemmer, like hands joined together, like the end and the way." This principle is disturbed by Genly Ai.
