“It takes a molecule to know a molecule”

“It takes a molecule to know a molecule” is Paul Slazinger’s wry formulation of likeness as the ground of understanding. In a conversation with Rabo Karabekian, the phrase moves from Slazinger’s account of himself to a joke about the locked potato barn, binding human recognition, literary thought, and the story’s withheld secrets without resolving what, exactly, one molecule can know about another.

The phrase and Slazinger’s self-conception

Slazinger’s molecule is first a way of describing the self he cannot simply choose to become. Before going to sleep, he tells Rabo that he cannot help being what he is, for good or ill, and calls himself “that sort of molecule.” He extends the image into a comic, cosmic predicament: until the Great Atom Smasher comes for him, this is the kind of molecule he has to be. The scale is deliberately disproportionate. A person’s enduring nature is rendered as a tiny particle awaiting an immense force, while the joke leaves intact the seriousness of his claim that his identity is not under voluntary control.

His account of literature follows the same reduction of scale. Literature, he says, is an insider’s newsletter about affairs concerning molecules, important to nothing in the universe except the few molecules afflicted with thought. The phrase “It takes a molecule to know a molecule” gives that vision a social counterpart: if thought makes human beings a peculiar class of matter, understanding may depend on belonging to that class and sharing its limitations. Literature is correspondingly intimate and restricted, a communication among beings whose concerns are negligible to the universe but substantial to one another.

The joking exchange in the potato barn

The saying returns when Slazinger speculates about Rabo’s potato barn. He announces that he has kept his theory locked in his head all these years in the barn and tells Rabo that he is not the only old man to have saved the best for last. Rabo challenges the apparent knowledge behind this inference by asking what Slazinger knows about the barn. Slazinger answers that he knows nothing, then reasons that an old man would not lock something away so tightly unless he were saving the best for last. He caps the guess with “It takes a molecule to know a molecule.”

The scene makes the expression both a claim of affinity and a knowingly flimsy proof. Slazinger does not possess information about what is in the barn; he reads Rabo’s secrecy through an imagined likeness between them. His confidence is therefore comic, but the joke also makes his attention relational: he treats Rabo’s concealment as something an old man might recognize because he, too, has kept something back. The barn becomes the material hinge between their talk of hidden theories and the possibility that Rabo has preserved a work of his own.

Rabo’s reply resists Slazinger’s neat division between a masterpiece and a failure. What is inside, he says, is neither the best nor the worst; it would not need to be very good to be the best thing he ever did, nor very bad to be the worst. He then asks whether Slazinger wants to know what is there. Slazinger says he does, if Rabo wants to tell him. The exchange stops at an invitation rather than a disclosure: the phrase helps open a conversation, but it does not itself reveal the barn’s contents.

Recognition, limits, and narrative function

The saying gathers together two scales that Slazinger has already set in tension. Molecules are insignificant against the universe, yet their capacity for thought makes their private affairs matter to one another. His maxim does not promise complete knowledge. In the barn conversation, Slazinger’s inference may be wrong, and his admission that he knows nothing makes the gap between sympathy and evidence explicit. The phrase is less a guarantee of accuracy than a compact expression of the hope that likeness can make another person’s secrecy legible.

Its recurrence also connects Slazinger’s larger reflections to an immediate exchange between friends. First the molecule names his stubborn selfhood and the narrow constituency of literature; then it becomes a teasing explanation for why he thinks he can read Rabo. That shift gives the maxim its warmth as well as its irony. Slazinger’s universal theory is tested not in the abstract but against one locked barn, one old man’s guarded answer, and one offered chance to see what has been kept inside.
