t is difficult to define the genre into which essays fall. Aldous Huxley, a leading essayist, gives guidance on the subject. He notes that "Like the novel, the essay is a literary device for saying almost everything about almost anything, usually on a certain topic. By tradition, almost by definition, the essay is a short piece, and it is therefore impossible to give all things full play within the limits of a single essay". He points out that "a collection of essays can cover almost as much ground, and cover it almost as thoroughly write my essay, as can a long novel"--he gives Montaigne's Third Book as an example. Huxley argues on several occasions that "essays belong to a literary species whose extreme variability can be studied most effectively within a three-poled frame of reference".
