Thoughts on Poetry and Its VarietiesJohn Stuart Mill

Mill published this essay in 1833 (revised 1859), and it contains his most considered statement on the nature of poetry and its distinction from other forms of literature. The central claim is arresting: poetry is not heard but overheard. "Eloquence is heard; poetry is overheard. Eloquence supposes an audience. The peculiarity of poetry appears to us to lie in the poet's utter unconsciousness of a listener."

The distinction separates poetry from rhetoric, oratory, and narrative. The novelist tells a story; the orator persuades an audience; the poet expresses feeling in a state of solitary absorption. What makes an utterance poetry is not its form (verse, meter, rhyme) but the quality of consciousness behind it. A poem is the expression of a state of feeling; a novel, even when written in verse, is the representation of external events.

Mill also distinguishes two temperaments among poets. The poet of nature (Shelley) feels spontaneously and intensely, while the poet of culture (Wordsworth) arrives at feeling through thought and reflection. Both are genuine, but they represent different relations between intellect and emotion.

The essay matters because it shifts the definition of poetry from the object to the subject, from what is said to the manner of consciousness from which it is said. This subjective turn in aesthetics will shape literary theory for a century.
