Is The Prelude a philosophical poem? It is, of course, many things besides: it is an autobiography; it contains profound reflections on psychology, education and politics; and there are passages of an almost purely lyrical character. Does it also contain philosophical poetry?
On this question, the critics of Wordsworth are divided. Coleridge and Raleigh answer Yes; Arnold, Bradley, Dr. Leaves, from their different points of view, agree in answering No. I believe that the first answer is right, although it has usually been supported by the wrong reasons. I believe the second answer to be wrong, although many of the arguments that are supposed to lead to it are in themselves sound enough. Those who say that The Prelude is not a philosophical poem, usually mean that it does not offer a coherent system of philosophy—that it expresses an original outlook and a personal wisdom, but that the only systematic philosophy in it comes at second-hand from Hartley or Coleridge and contributes not at all to the poem. And this is largely true. But the mistake is, to identify philosophy with system, philosophizing with “a philosophy.” This is a mistake that has been repudiated again and again by many of the greatest philosophers, from Socrates and Plato to Locke and Kant and others.
I shall argue that The Prelude achieves philosophical poetry, because in it Wordsworth grapples with philosophical problems—problems which arise out of the story of his own early life—which are actually forced upon him by the poem itself; and because he tries to answer these problems in a way which would be possible only in poetry.
