Hagiographies of science

“The hagiographies of science are full of paeans to the self-correcting, self-healing nature of the enterprise. But if raw results are so often false, the filtering mechanisms so ineffective, and the self-correcting mechanisms so compromised and slow, then science’s approach to truth may not even be monotonic. That is, past theories, now “refuted” by evidence and replaced with new approaches, may be closer to the truth than what we think now. Such regress has happened before: In the nineteenth century, the (correct) vitamin C deficiency theory of scurvy was replaced by the false belief that scurvy was caused by proximity to spoiled foods. Many ancient astronomers believed the heliocentric model of the solar system before it was supplanted by the geocentric theory of Ptolemy. The Whiggish view of scientific history is so dominant today that this possibility is spoken of only in hushed whispers, but ours is a world in which things once known can be lost and buried.” from Scientific Regress by William A.
