This book, regarded as a classic by some, is not about poetry per se. It's about Platonic Truth. (1) Eternal, external notions exist in an independent realm. Real poets, pure poets, are able to discern these truths via poetic intuition. Certain words and wordings with surface meaning are, really, but reflections of non-material, higher Reality. Only the poetic philosophers have the capacity to discern through poetic expression and use of metaphors and such. (2) Modern science in contrast is lost and mired in the mundane. They focus on parts of wholes, but never the whole as such. Science is about "the haphazard pull-and-push ignorance which claims in public the name of science and admits in private that it knows nothing; which, when it turns inward to the mind of the Knower, finds there a nothingness within, to match the nothingness without." (3).
Meaning - Reality itself - lives only in the higher, external realm. Criticism of such a reality is based on ignorance, which is the inability to discern properly. In this way, poetic philosophy immunizes itself from criticism. Truth, after all, is beyond common understanding. As an illustration of such, Barfield notes a problem with "the interpretation of Greek philosophy by modern Europeans. Such a one can read Plato and Aristotle through," he writes, "from end to end, he can even write books expounding their philosophy, and all without understanding a single sentence. Unless he has enough imagination and enough power of detachment from the established meanings or thought-forms of his own civilization, to enable him to grasp the meanings of the fundamental terms -- unless, in fact, he has the power not only of thinking but of unthinking -- he will simply re-interpret everything they say in terms of subsequent thought." Of course, a critic can respond, tolerantly and simply, with that's fine" and still wonder "why it is that the Barfield poet must live in an illusory world?" Here, "must" is a poetic word. Does it mean that Barfield's poet-philosopher needs an eternal world? Does he or she fear its absence? Or is his or her Meaning the product of both need and fear?
(1) In the preface to the second edition, the author highlights the book's subtitle, "A Study in Meaning," by saying that the book "claims to present, not merely a theory of poetic diction, but a theory of poetry: and not merely a theory of poetry, but a theory of knowledge." Knowledge is about preexisting, primal archetypal realities ("Mind existed, as Life, and Meaning, before it become conscious of itself, as knowledge"). Barfield refers to the older, pure poets who drew "from primal source of Meaning." Actually, and interestingly, Barfield sees pure poetry preceding Plato's process of intuitive apprehension of Meaning. Plato was but a reflection of something deeper, richer and more archetypically primal. This was earlier Greek society that experienced a unified reality, as opposed to an analytic breaking down of reality into its component parts. "Thus," Barfield writes, "the old, instinctive consciousness of single meanings, which comes down to us as Greek myths, is already fighting for its life by Plato's time as the doctrine of Platonic Ideas (not 'abstract', though this word is often erroneously used in English translations)..."
(2) In the beginning, the role of mind in apprehending was minimal. "These primary 'meanings,' Barfield comments, "were given, as it were, by Nature, but the very condition of their being given was that they could not at the same time be apprehended in full consciousness; they could not be known, but only experienced, or lived." This experience of life (Nature) was of a unity and "the language of primitive men reports them as direct perceptual experience. The speaker has observed a unity, and is not therefore himself conscious of relation." With the evolution of consciousness, unified nature breaks down, following the analytic principle, into its component parts and with it, poetry loses something in Barfield's way of thinking that is wholly significant: losing our connection with the whole, which is Meaning, "the principle of living unity." This inability to discern properly, to discover - see, experience - what was once there but now is lost is, for Barfield, the definition of bad poetry. The good poet is one who enlivens words with mythical content. Words can be traced back to their roots that have mythical foundation, and mythical foundation because they represent something primal and true: "if one traces them back far enough, one reaches a period at which their meaning had a mythical content." Later, he adds that "As we go back in history, language becomes more picturesque, until its infancy, when it is all poetry; or all spiritual facts are represented by natural symbols." Mythology, he says "is the ghost of concrete meaning. Connections between discrete phenomena, connections which are now apprehended as metaphor, were once perceived as immediate realities. As such the poet strives, by his own efforts, to see them, and to make others see them, again." That poet could be seen as "possessed" or the recipient of a divine "wind," filled with "archetypal strangeness," in contrast to today's poet who is "more inclined to think of inspiration as a mood -- a mood that may come and go in the course of a morning's work."
(3) Barfield describes the evolution of consciousness as the "ascending rational principle and the descending poetic principle." Unity of the latter, in other words, gives way in the evolution of consciousness to the analytic preoccupation of the former. In this way, the rational principle is "the anti-poetic." Though critical of modern science, Barfield also sees no distinction between "Poetry and Science as modes of experience." In stating that the "rational principle must be strongly developed in the great poet," he re-instates Plato's sense of rationality. But then he goes on to ask, "Is it necessary to add to this that the scientist, if he has 'discovered' anything, must also have discovered it by the right interaction of the rational and poetic principles? Really, there is no distinction between Poetry and Science, as kinds of knowing, at all. There's is only a distinction between bad poetry and bad science." It is interesting that Barfield stakes out a claim on science like this, which could be interpreted only as the science of (rational) knowing about Mind as an external, independent reality. While of course cosmic reality is external, independent, Barfield is referencing something quite different: the reality of Being that stands above and creates such a reality.
