"The progress of science is strewn, like an ancient desert trail, with the bleached skeleton of discarded theories which once seemed to possess eternal life"
About this Quote
The barb is in “once seemed to possess eternal life.” He’s skewering the human impulse to treat provisional models as scripture the moment they start working. The line isn’t anti-science so much as anti-complacency: the real enemy is certainty disguised as rigor. By comparing theories to bodies, he also underlines how social and psychological science is. A theory can “seem” immortal because communities invest status, careers, and identity in it. When it dies, it doesn’t die quietly; it leaves remains.
Context matters: Koestler came of age amid ideological systems that marketed themselves as scientific and inevitable, then collapsed into catastrophe. As a novelist and public intellectual skeptical of closed certainties, he’s alert to how “progress” can be narrated as destiny. His metaphor punctures that story. It suggests that what we call advancement is partly an archive of abandoned metaphysics, and that the best safeguard against dogma is remembering how many “eternal” explanations ended up as bone in the sun.
