Thomas Pynchon, The Crying of Lot 49

(Cross-posted from Commonplace)

Oedipa, perverse, had stood in front of the painting and cried. No one had noticed; she wore dark green bubble shades. For a moment she'd wondered if the seal around her sockets were tight enough to allow the tears simply to go on and fill up the entire lens space and never dry. She could carry the sadness of the moment with her that way forever, see the world refracted through those tears, those specific tears, as if indices as yet unfound varied in important ways from cry to cry.

She looked down a slope, needing to squint for the sunlight, onto a vast sprawl of houses which had grown up all together, like a well-tended crop, from the dull brown earth; and she thought of the first time she'd opened a transistor radio to replace a battery and seen her first printed circuit. The ordered swirl of houses and streets, from this high angle, sprang at her now with the same unexpected, astonishing clarity as the circuit card had. Though she knew even less about radios than about Southern Californians, there were to both outward patterns a hieroglyphic sense of concealed meaning, of an intent to communicate. There'd seemed no limit to what the printed circuit could have told her (if she had tried to find out); so in her first minute of San Narciso, a revelation also trembled just past the threshold of her understanding.

She could, at this stage of things, recognize signals like that, as the epileptic is said to--an odor, color, pure piercing grace note announcing his seizure. Afterward it is only this signal, really dross, this secular announcement, and never what is revealed during the attack, that he remembers. Oedipa wondered whether, at the end of this (if it were supposed to end), she too might not be left with only compiled memories of clues, announcements, intimations, but never the central truth itself, which must somehow each time be too bright for her memory to hold; which must always blaze out, destroying its own message irreversibly, leaving an overexposed blank when the ordinary world came back. In the space of a sip of dandelion wine it came to her that she would never know how many times such a seizure may already have visited, or how to grasp it should it visit again. Perhaps even in this last second--but there was no way to tell.

"I came," she said, "hoping you could talk me out of a fantasy."

"Cherish it!" cried Hilarius, fiercely. "What else do any of you have? Hold it tightly by its little tentacle, don't let the Freudians coax it away or the pharmacists poison it out of you. Whatever it is, hold it dear, for when you lose it you go over by that much to the others. You begin to cease to be."
