coming of age as the main theme of the book, and wrote in a 1973 essay that she chose that theme since she was writing for an adolescent audience. She stated that "Coming of age ... is a process that took me many years; I finished it, so far as I ever will, at about age thirty-one; and so I feel rather deeply about it. So do most adolescents.

She also said that fantasy was best suited as a medium for describing coming of age, because exploring the subconscious was difficult using the language of "rational daily life".

Equilibrium and Taoist themes The world of Earthsea is depicted as being based on a delicate balance, which most of its inhabitants are aware of, but which is disrupted by somebody in each of the original trilogy of novels. This includes an equilibrium between land and sea (implicit in the name Earthsea), and between people and their natural environment. In addition to physical equilibrium, there is a larger cosmic equilibrium, which everybody is aware of, and which wizards are tasked with maintaining. Describing this aspect of Earthsea, Elizabeth Cummins wrote, "The principle of balanced powers, the recognition that every act affects self, society, world, and cosmos, is both a physical and a moral principle of Le Guin's fantasy world." The concept of balance is related to the novel's other major theme of coming of age, as Ged's knowledge of the consequences of his own actions for good or ill is necessary for him to understand how the balance is maintained.

At the end of the novel, Ged may be seen to embody the Taoist way of life, as he has learned not to act unless absolutely necessary. He has also learned that seeming opposites, like light and dark or good and evil, are actually interdependent. Light and dark
