Literary and artistic theory
In his essay "The Poetic Principle", Poe would argue that there is no such thing as a long poem, since the ultimate purpose of art is aesthetic, that is, its purpose is the effect it has on its audience, and this effect can only be maintained for a brief period of time (the time it takes to read a lyric poem, or watch a drama performed, or view a painting, etc.). He argued that an epic, if it has any value at all, must be actually a series of smaller pieces, each geared towards a single effect or sentiment, which "elevates the soul".
Poe associated the aesthetic aspect of art with pure ideality claiming that the mood or sentiment created by a work of art elevates the soul, and is thus a spiritual experience. In many of his short stories, artistically inclined characters (especially Roderick Usher from "The Fall of the House of Usher") are able to achieve this ideal aesthetic through fixation, and often exhibit obsessive personalities and reclusive tendencies. "The Oval Portrait" also examines fixation, but in this case the object of fixation is itself a work of art.
He championed art for art's sake (before the term itself was coined). He was consequentially an opponent of didacticism, arguing in his literary criticisms that the role of moral or ethical instruction lies outside the realm of poetry and art, which should only focus on the production of a beautiful work of art. He criticized James Russell Lowell in a review for being excessively didactic and moralistic in his writings, and argued often that a poem should be written "for a poem's sake". Since a poem's purpose is to convey a single aesthetic experience, Poe argues in his literary theory essay "The Philosophy of Composition", the ending should be written first. Poe's inspiration for this theory was Charles Dickens, who wrote to Poe in a letter dated March 6, 1842,
Apropos of the "construction" of "Caleb Williams," do you know that Godwin wrote it backwards, - the last volume first, - and that when he had produced the hunting down of Caleb, and the catastrophe, he waited for months, casting about for a means of accounting for what he had done?
Poe refers to the letter in his essay. Dickens's literary influence on Poe can also be seen in Poe's short story "The Man of the Crowd." Its depictions of urban blight owe much to Dickens and in many places purposefully echo Dickens's language.
He was a proponent and supporter of magazine literature, and felt that short stories, or "tales" as they were called in the early nineteenth century, which were usually considered "vulgar" or "low art" along with the magazines that published them, were legitimate art forms on par with the novel or epic poem. His insistence on the artistic value of the short story was influential in the short story's rise to prominence in later generations.
Poe often included elements of popular pseudosciences such as phrenology and physiognomy in his fiction.
Poe also focused the theme of each of his short stories on one human characteristic. In "The Tell-Tale Heart", he focused on guilt, in "The Fall of the House of Usher", his focus was fear, etc.
Much of Poe's work was allegorical, but his position on allegory was a nuanced one: "In defence of allegory, (however, or for whatever object, employed,) there is scarcely one respectable word to be said. Its best appeals are made to the fancy - that is to say, to our sense of adaptation, not of matters proper, but of matters improper for the purpose, of the real with the unreal; having never more of intelligible connection than has something with nothing, never
