Truth-to-Nature
Daston and Galison's name for the pre-photographic regime of scientific representation — in which illustrators synthesized ideal forms from accidental specimens, and the image's authority derived from the trained judgment of the expert hand.
Truth-to-nature was the dominant epistemic virtue of eighteenth- and early-nineteenth-century scientific atlases. The botanical illustrator did not record the specimen in front of her; she produced an image of the species, smoothing insect damage, straightening crooked stems, purifying the particular into the essential. The practice was not considered dishonest. It was the highest form of scientific representation, grounded in a coherent epistemology: nature's individual instances were noisy, and the illustrator's trained eye was the instrument of selection that revealed the underlying form. Daston's historical claim is that this was not a primitive precursor to real objectivity but a fully developed epistemic regime with its own confidence artifacts, its own warranted successes, and its own characteristic distortions that its internal standards could not detect.

The confidence artifact of truth-to-nature was aesthetic authority. The clean lines, the precise rendering of venation, the careful attention to three-dimensional form — these features communicated that the illustrator understood her subject
