Mill’s argument continues: both poetry and fiction contain truth, but in case of poetry the truth is about inward things, the emotions, while in in case of fiction it is about giving a true picture of life. That is why “great poets are often proverbially ignorant of life”, because they really don’t know it, they only know their own emotional life. Of course both poetry and narrative can be combined to a different degree within one work, and this is true especially for drama. Again, a dramatic poem may contain a lot of great poetry and very scanty incidents, while trashy novels from the Minerva Press may be quite good as narratives, although no poetic or emotional truth. I guess Mill indicates here quite clearly which branch of literature he prefers, and he further tips his hand when he says about Shakespeare that to the many, he is a great storyteller, while to the (select) few he’s a great poet.
What about descriptive poetry, you might ask? Description is not really poetry, nor can science be poetry, even though it could be the subject of a didactic poem, but they can give inspiration to poetry. Still, the poet’s way of describing, say, a lion, would be very different from that of a naturalist or a traveller, because poets would focus on the emotions evoked in the viewer.
Mill also discusses the two definitions of poetry he read recently, one by a rather forgotten poet (although apparently a very interesting man) Ebenezer Elliott, the other by the unsigned (as was customary then) author writing for Blackwood’s Magazine. Since Mill calls these authors “poets, and men of genius”, I assume he knew the identity of the latter and I wish the editors of the NAEL had told me if it was the case. Elliott wrote that “”poetry is impassioned truth”, the other wrote that poetry is “man’s thoughts tinged by his feelings”. These are very good definitions, says Mill, and yet, how do we make a difference between poetry and eloquence, to which they also could apply? Poetry, he thinks, is always “overheard”, it’s like eavesdropping on the poet’s thoughts, while eloquence expressly addresses (or interrogates) the listener or reader. It’s aim is to influence its recipients in some way.
