C.S. Lewis’s Argument from Nostalgia

(or, “Why you sometimes feel like you can remember something, sometimes, from even before your childhood”)


C.S. Lewis often wrote about (and alluded to) the sense of “nostalgia” that comes with beholding a beautiful landscape.

One of my recent backpacking trips. Observe the bursting sense of nostalgia.

I’ve always thought that the Christian argument from beauty/awe/nostalgia is one of the most difficult to convincingly express, yet one of the most powerful when properly understood. It shares some commonality with the Argument from Religious Experience, in that it relies on personal revelation rather than hard evidence (historical & scientific data) or soft evidence (formal philosophical arguments).

Rather than relying upon another person’s (oftentimes unreliable) testimony, however, the argument from nostalgia encourages self-reflection by identifying a peculiar sensation – almost like déjà vu, or a lost memory, or a half-forgotten dream – that seems to be shared by most people. C.S. Lewis described this sensation as follows:

“In speaking of this desire for our own faroff country, which we find in ourselves even now, I feel a certain shyness. I am almost committing an indecency. I am trying to rip open the inconsolable secret in each one of you—the secret which hurts so much that you take your revenge on it by calling it names like Nostalgia and Romanticism and Adolescence; the secret also which pierces with such sweetness that when, in very intimate conversation, the mention of it becomes imminent, we grow awkward and affect to laugh at ourselves; the secret we cannot hide and cannot tell, though we desire to do both. We cannot tell it because it is a desire for something that has never actually appeared in our experience. We cannot hide it because our experience is constantly suggesting it, and we betray ourselves like lovers at the mention of a name. Our commonest expedient is to call it beauty and behave as if that had settled the matter. Wordsworth’s expedient was to identify it with certain moments in his own past. But all this is a cheat. If Wordsworth had gone back to those moments in the past, he would not have found the thing itself, but only the reminder of it; what he remembered would turn out to be itself a remembering. The books or the music in which we thought the beauty was located will betray us if we trust to them; it was not in them, it only came through them, and what came through them was longing. These things—the beauty, the memory of our own past—are good images of what we really desire; but if they are mistaken for the thing itself they turn into dumb idols, breaking the hearts of their worshippers. For they are not the thing itself; they are only the scent of a flower we have not found, the echo of a tune we have not heard, news from a country we have never yet visited.”

When I first encountered that passage, I remember being stunned. I had to re-read it several times. It almost seemed as if Lewis had ripped something from my own mind and memories, and put it to paper half a century before I was born.

The association between nostalgia and childhood is particularly intriguing. While childhood clearly isn’t the source of this particular type of nostalgia, the sensation seems to be strongest in the context of one’s childhood. Something to do with innocence, maybe? Lewis goes on:

“Almost our whole education has been directed to silencing this shy, persistent, inner voice; almost all our modern philosophies have been devised to convince us that the good of man is to be found on this earth.”

And here is where we make the leap from “peculiar shared sensation” to “argument for Christian theism”. Lewis again:

“Apparently, then, our lifelong nostalgia, our longing to be reunited with something in the universe from which we now feel cut off, to be on the inside of some door which we have always seen from the outside, is no mere neurotic fancy, but the truest index of our real situation. And to be at last summoned inside would be both glory and honour beyond all our merits and also the healing of that old ache.”

“Creatures are not born with desires unless satisfaction for those desires exists. A baby feels hunger: well, there is such a thing as food. A duckling wants to swim: well, there is such a thing as water. Men feel sexual desire: well, there is such a thing as sex. If I find in myself a desire which no experience in this world can satisfy, the most probable explanation is that I was made for another world. If none of my earthly pleasures satisfy it, that does not prove that the universe is a fraud. Probably earthly pleasures were never meant to satisfy it, but only to arouse it, to suggest the real thing.”
