… discussions that mention the Great Library and/or the supposed impact of Christianity on “progress”, with the idea being that the Scientific and Industrial Revolutions were due on some kind of inevitable deterministic historical timetable but were wantonly derailed “for a thousand years” by the destruction of the Great Library, which is supposedly why we don’t live on the moons of Jupiter.
The problem with all this is not just that the scholars of the Mouseion were rather more interested in the textual variants of Pindar’s paianes than studying physics, but also a common modern misunderstanding about the nature of Greek “science”. Many modern people, including modern scientists, hear about the Greeks discussing motion or “atoms” or doing geometry to measure the circumference of the Earth or the distance to the Sun and assume that they were doing “science” in the modern sense of the word. Historians also sometimes refer to Greek natural philosophy as “science” and popularisations of the history of science draw simplistic direct lines between things like Greek discussions of “atoms” and modern atomic theory. But this obscures the fact that Greek proto-science was, while a distant lineal ancestor of the modern sciences, very unlike them in many important respects. At best, it was a highly rational attempt at understanding fundamental precepts of the physical and natural world. But it used induction and common sense more than measurement and experiment. There were exceptions (mainly in geometry and its related field, astronomy), but the Greeks were usually not interested in empirical measurement and so were usually even less interested in genuine experiments. Most Greek proto-science was a highly abstract and philosophical affair, based on some observations, but without modern ideas of carefully designed and repeatable experiments with calibrated measurement and attendant mathematics. Most of their “science” was done by sitting around, thinking and talking about concepts, not by actually dropping weights from towers – though they did do thought experiments which sometimes led to correct conclusions and sometimes did not. Their “science” was not our science.
This means that a Greek conversation about “atoms” was largely an abstract and metaphysical exercise about the philosophical nature of a thing and how many times it could be divided conceptually and what this may mean; the word comes from the Greek ἄτομος meaning “unhewn, uncut, indivisible”. No Greek philosopher walked away from such a conversation and decided to try to build some equipment to explore the physical nature of atomic structure and would probably have considered such an idea absurd. Nor would they have taken the step of considering that different forms of matter, liquid or gas were made up of different combinations of atoms and so decide to experiment with these substances to understand this better, since this was completely contrary to their (erroneous) conception of the “Four Elements” of Earth, Air, Water and Fire. The nature of Greek thought did allow them to draw useful and often correct conclusions about the physical universe, but it also set up barriers to the true scientific method that they simply did not and could not cross.
This was one of the reasons there was no direct link between their proto-scientific “science” and technology. Natural philosophy was, as the term would suggest, the preserve of philosophers. In a world where most of the population had to be devoted to agricultural production and most of the rest often barely got by, sitting around and talking about abstractions like “atoms” was a rich man’s luxury. Most philosophers either came from the upper class (though maybe its lower echelons in many cases) or had rich patrons or both, which meant most philosophers had little interest in making or inventing things: that was generally the preserve of lowly mechanics and slaves. Again, there were exceptions to this – Archimedes seems to have had some interest in the engineering applications of his ideas, even if most of the inventions attributed to him are probably legends. On the whole, however, lofty Greek philosophers didn’t think to soil their hands with something as lowly as inventing and making things.
