There is a great line in CS Lewis’s Perelandra that summarizes a theme found in most of Lewis’ writing and that is, “the sweet poison of the false infinite.” The idea is pretty straightforward, but the wording, in typical Lewis fashion, is just tight. Basically Lewis’s insight is that we humans have a desire, a longing for God himself. That is, we long to be filled with, and satisfied by, the infinite.
We often attempt, however, to satisfy this longing or desire with objects that are not suited to fill the gap. And this is the point: Everything, other than God, is incapable of satisfying our heart’s desire; they are in this sense a “false infinite.” That is, they promise to satisfy, but upon gaining them we find that they held out false promises. What makes the situation even worse is that the “false infinite” can taste sweet; the goodness of the created world is in fact sweet and should be enjoyed, but it cannot satisfy in the way we hope. We can convince ourselves, however, that the lack of satisfaction just means we needed more of the supposed antidote. Hence we become poisoned into thinking that the temporal sweetness was a foresight into a complete and eternal satisfaction that the “false infinite” is actually unable to deliver.
One blatant example of this principle is in The Lion, the Witch and the Wardrobe. Recall when Edmund visits Narnia for the first time he meets the white witch who gives him whatever he wants to eat. Edmund asks for Turkish Delight of course. But this is magic Turkish Delight. The more he eats the more he wants; the more he eats the sicker he feels, and yet he wants more. This desire for Turkish Delight begins to cause the ruin of Edmund. He can no longer appreciate the common pleasures of other food because the desire for Turkish Delight has become so consuming and yet so unsatisfying. This is basically what Lewis conceives hell to be like; people infatuated with the wrong objects of desire that not only remain unmet, but consume the one who is taken by them. It’s a horrible cycle.
So we find ourselves in an interesting position. We hunger for something that is not given in our experience, but yet things in our experience remind us of that for which we hunger. Hence we are tempted as Edmund was by the “sweet poison of the false infinite.” But to fill the hunger with the “false infinite” will invariably ruin our appetite for the appropriate food, namely, God. To resolve this tension, Lewis suggest we take on the dialectic of enjoyment and renunciation. That is, we are free to enjoy those things that are given to us in our experience. And yet we must all the while renounce them as the real satisfaction to our longings.
As Lewis puts it in The Problem of Pain, “The settled happiness and security which we all desire, God withholds from us by the very nature of the world: but joy, pleasure, and merriment He has scattered broadcast. We are never safe, but we have plenty of fun, and some ecstasy. It is not hard to see why. The security we crave would teach us to rest our hearts in this world and oppose an obstacle to our return to God: a few moments of happy love, a landscape, a symphony, a merry meeting with our friends, a bathe, or a football match, have no such tendency. Our Father refreshes us on the journey with some pleasant inns, but will not encourage us to mistake them for home.”
It is quite easy to be captivated by the “sweet poison of the false infinite”; to keep mistaking the inns for home. And this is all the while ruining our appetite for God. There are so many things I have been trusting in to make me secure and satisfied, but they have in the end shown themselves to be “false.” We do well to pay close attention to the yearnings of your own heart because, as Lewis says, our desires will always reveal the falsity of other gods.
