 How have scientists' positionality toward their research subjects changed since the 20th century?
A scream of brakes, the splash into icy waters, a long descent into alkaline depths ... Movement was slower now, as he began to sink, trapped inside his wrecked car. The ripples that had ruffled the surface waters in the Pit, quieted again to glassy smoothness. Lacking qualities identifiable as human, the disturbance was still like the babble of a group of workmen who have discovered something remarkable. The icy breeze tore tiny puffs of dust from grotesque, angling drifts of soil, nearly waterless for eons. Glacial ages, war, decadence, disease, and a final scattering of those ultimate superhumans to newer worlds in other solar systems, had done that. Man, it seemed, had a successor, as ruler of the Earth. Loy Chuk had flown his geological expedition out from the far lowlands to the east, out from the city of Kar-Rah. He could think and dream and invent, and the civilization of his kind was already far beyond that of the ancient Twentieth Century. The dry mud that had encased it like an airtight coffin, had by now been chipped away by the tiny investigators; but soiled clothing still clung to it, after perhaps a million years. A mineral saturation that had held time and change in stasis. A perfect preservative for organic tissue, aided probably during most of those passing eras by desert dryness. Not the star-conquering demi-gods, but the ancestral stock that had built the first machines on Earth, and in the early Twenty-first Century, the first interplanetary rockets. A strange accident, happening in a legendary antiquity, had aided them in their quest for knowledge. The final instrument he used to test the mummy, looked like a miniature stereoscope, with complicated details. Medical and biological sciences were far advanced among Loy Chuk's kind. It might move, speak, remember its past! The spreading continental plateau of North America seemed to crawl backward, beneath. Beyond the eastern rim of the continent, the plain dipped downward steeply. Loy Chuk's people had built their homes mostly underground, since the beginning of their foggy evolution. Fluids submerged it, slowly soaking from that hardened flesh the alkali that had preserved it for so long. The fluid was changed often, until woody muscles and other tissues became pliable once more. Still submerged in liquid, the corpse was submitted to a flow of restorative energy, passing between complicated electrodes. The cells of antique flesh and brain gradually took on a chemical composition nearer to that of the life that they had once known.
