interest in mythology, and her exposure to cultural diversity as a child. Her protagonists are frequently interested in the cultures they are investigating, and are motivated to preserve them rather than conquer them. Authors that influenced Le Guin include Victor Hugo, Leo Tolstoy, Virginia Woolf, Italo Calvino, and Lao Tzu. Le Guin identifies herself with feminism, and is interested in non-violence and ecological awareness. She has participated in demonstrations against the Vietnam War and nuclear weapons. These sympathies can be seen in several of her works of fiction, including the Hainish universe works. The novels of the Hainish universe frequently explore the effects of differing social and political systems, although she displays a preference for a "society that governs by consensus, a communal cooperation without external government." Her fiction also frequently challenges accepted depictions of race and gender. The novel was originally named "Little Green Men," in reference to the common science-fiction trope. In her introduction to the 1976 edition, Le Guin stated that she was concerned at the exploitation of the natural world by humans, particularly in the name of financial gain, and that this concern drove her story. Setting The Word for World is Forest is set in the fictional Hainish universe, which Le Guin introduced in her first novel Rocannon's World, published in 1966. In this alternative history, human beings did not evolve on Earth, but on Hain. The people of Hain colonized many neighboring planetary systems, including Terra (Earth) and Athshe, possibly a million years before the setting of the novels. The planets subsequently lost contact with each other, for reasons that Le Guin does not explain. Le Guin does not narrate the entire history of the Hainish universe at once, instead letting readers piece it together from various works. The novels and other fictional works set in the Hainish universe recount the efforts to re-establish a galactic civilization. Explorers from Hain as well as other planets use interstellar ships taking years to travel between planetary systems, although the journey is shortened for the travelers due to relativistic time dilation, as well as through instantaneous interstellar communication using the ansible, introduced in The Dispossessed. At least two "thought experiments" are used in each novel; the background idea of a common origin for all the humanoid species, and a second idea unique to each novel. In The Word for World is Forest, the second thought experiment is
