Perhaps the best thing about James Scott's Seeing Like a State was being exposed to this book. Just reading Scott's references made the book intriguing, and I was entirely prepared to discover that Scott had already mined the best of Kula's insights. But no, this book is a pleasure to read from start to finish about a topic that at first glance is utterly mundane, but absolutely essential to understanding pre-modern life. How was land measured? How was grain/in kind tax measured? Such basic questions, and yet until a month before it had never seemed necessary. To be sure, as a modern historian focused on the state and nationality, it was not relevant to my research, but suddenly it mattered.
The key point is the variation of measures. Some of this is just a natural result of the localized world people lived in, but there are also practical concerns. For example, one aspect of these differences was that in the Polish grain trade, the measurements for grain upstream were larger than those downstream, with prices increasing as well, so that the difference was an alternative way to deal with shipping costs in a pre modern world. Similarly, the discussion of bread prices and the way these worked in a pre-modern world where the presumption was that prices should stay the same, and so over time the size of loaves declined.
That said, it is a quirky book. The first part focuses on Europe in the general thought towards the end Medieval and early modern Poland gets attention. Part II focuses entirely on Poland, while Part III deals with efforts introduce standardized measurements, and how the French Revolution facilitated that. The last part focuses on how the metric system took hold first in France, and then slowly at first in other parts of Europe. It is a lopsided organization, where paradoxically the chapters in part one are generally quite short, while the later parts have longer chapters.
