When attempting to define what something is, it is often helpful to define what something is not. It is also important to note that many literary critics attempt to classify novels and literary works in only one genre, such as "romantic" or "naturalist", not always taking into account that many works fall into multiple categories.[13] Much discussion is cited from Maggie Ann Bowers' book Magic(al) Realism, wherein she attempts to delimit the terms magic realism and magical realism by examining the relationships with other genres such as realism, surrealism, fantastic literature, science fiction and its African version, the Animist Realism.
