Every claim below was made in this piece, quoted word for word and numbered in the order the piece makes them, so you can read it there rather than take our word for it. The sentence above each quote is our reading of the claim, not their wording. Each quote was checked against a stored copy of the page at build time; where the two differ, the quote is the fact.

  1. The thing is, being a particularly complex or efficient agrarian economy doesn’t seem to have been the most important thing for producing the industrial revolution or it almost certainly would have happened earlier and probably not in Europe.
  2. The specificity matters here because each innovation in the chain required not merely the discovery of the principle, but also the design and an economically viable use-case to all line up in order to have impact.
  3. If you had given the Romans the designs for a Newcomen steam engine, they couldn’t have built it without developing whole new technologies for the purpose (or casting every part in bronze, which introduces its own problems) and then wouldn’t have had any profitable use to put it to.
  4. All of which is why simple graphs of things like ‘global historical GDP’ can be a bit deceptive: there’s a lot of particularity beneath the basic statistics of production because technologies are contingent and path dependent.
  5. New land can be brought under cultivation (or cultivated more intensively) of course, but marginal gains decrease rapidly (because the best land is cultivated first and because adding more labor to already cultivated land, while it can increase harvests, is less efficient than cultivating new land) and there is a fairly hard ceiling on total production of this sort that was, for the most part, fairly low.
  6. Roman economic growth, because it was a product of institutions instead of technologies, was not durable in the face of those institutions collapsing.
  7. In my view the key takeaway here is just how contingent the industrial revolution was: the industrial revolution that occured required a number of very specific pre-conditions which were really on true on Great Britain in that period.
  8. As much as we might want to imagine that the greater currents push historical events largely on a predetermined path with but minor variations from what must always have been, in practice events are tremendously contingent on unpredictable variables.
