Compare like with like
Pomeranz asks why sustained industrial growth began in northwestern Europe. His comparison challenges stories that treat all of Europe and all of China as uniform units. The publisher’s account emphasizes similarities between advanced regions and the ecological constraints they faced before industrial divergence.
Look for the constraint that changed
The book gives coal and access to resources from the New World a central role in explaining how parts of Europe escaped land-intensive limits. This is a change in the explanation: success cannot be read backward as proof that one region had always possessed every decisive advantage. Contingent access to energy and overseas resources matters alongside developments inside Europe.
Do not turn a revision into a monocausal story
The practical lesson for reading historical arguments is methodological. Check the units being compared, the period under discussion, and the proposed causal mechanism. Similarity on one measure does not prove equality on every measure; the importance of coal does not make institutions irrelevant. Pomeranz’s account is an influential intervention in a continuing debate. Ask what evidence would distinguish a resource-constraint explanation from a claim that earlier cultural or institutional differences already made the outcome inevitable.
