Tolkien scholar Verlyn Flieger has written incisively on the theme of “splintered light” in Tolkien’s work, which she interprets in terms of the occasional Inkling Owen Barfield’s thesis that language, meaning, and human perception change over time from a more authentic, mythic, unified state to a more fragmented, differentiated, and profuse state. As Tolkien himself writes in one letter, the Light of the Two Trees of Valinor, “derived from light before any fall,” symbolizes the “light of art undivorced from reason, that sees things both scientifically (or philosophically) and imaginatively (or subcreatively) and says that they are good–as beautiful” (L 148n). Part of Tolkien’s goal in his legendarium, as I’ve suggested previously, was to recover a lost vision of these now-divergent perspectives in their supposedly original, mythic unity.
As I’ve also noted before, however, there is a tendency in some readers to interpret such Tolkienian images in terms of a Neoplatonic, tragic metaphysics of emanation, according to which reality and meaning become more and more diminished or diluted the further they get from their originating source. In this context, accordingly, it is interesting to note that the light of the Two Trees, which Tolkien identifies as an authentic, unified, “undivorced” light of scientific or philosophical reason and sub-creative imagination, is in another sense not a primordial unity at all, but is itself the result of a sub-creative “blending” of two different light sources (in this case, the golden rain of Laurelin and the silver dew of Telperion). Put differently, the Light of Valinor is not just an authentically pre-splintered light, but already an unsplintering (if you will) of post-splintered light. The blended light of the Two Trees, in other words, is a symbol not of an original or natural–but of a sub-created (and in that sense “artificial”) and achieved–unity.
When we realize this, we may fairly see that in his image Tolkien treats us to a wonderful metaphor for understanding the import of his own legendarium, namely the harmonious and complementary synthesis of myth and fantasy on the one hand and analytical, scholastic reasoning on the other. If so, more than merely dramatizing Barfield’s thesis about the tendency of human thought to self-differentiate and fragment over time, the aim of Tolkien’s own fiction is to help heal this modern perceptual breach by re-envisioning the world in a way that satisfies at once the human powers of both imagination and reason. Tolkien’s entire legendarium, in short, simply is the Light of Valinor, the powerfully fruitful and mutually fructifying mingling of the twin lights of reason and imagination.
As Tolkien well knew, such light can be and in fact has been “splintered,” “fractured,” and hence diminished and lost. When Saruman boasts that “white light can be broken,” Gandalf doesn’t contest the achievement so much as he questions its prudence and desirability: “In which case it is no longer white… And he that breaks a thing to find out what it is has left the path of wisdom.” But as a Christian Tolkien also believed that there was a way of changing the original light of God’s creation–and that by God’s own design and ordination–that resulted in more, not less, light. In his poem “Mythopoeia” he puts it in terms that, at first glance, may seem curiously Sarumanian: “Man, Sub-creator, the refracted light / through whom is splintered from a single White / to many hues, and endlessly combined / in living shapes that move from mind to mind.” Man the Sub-creator does indeed “refract” and “splinter” God’s “White light” of creation, but he does so (properly) only in order that he might then re-“combine” that light into even more “living shapes” that may “move from mind to mind.” Tolkien gives us a profound, positive, even comic image, finally, of this paradoxical, anti-entropic tendency of sub-creative light to escalate and multiply itself in an early account of the Two Trees of Valinor, in which it said that “of their growth and being did they ever make light in great abundance still over and beyond that which their roots sucked in…” This cross-pollination of sub-creative light is hardly a Neoplatonic outlook of a tragic, ever-diminishing reality, truth, and meaning–the metaphysical and semantic equivalent of Bilbo’s “butter scraped over too much bread”–but is more akin to the prophet Ezekiel’s eucatastrophic vision of the Gospel as a living stream flowing from the Temple: the further it gets from its source, the wider and deeper the water becomes.
