 A new strand of writing on the problem of coordination has emerged in recent years, consisting most notably of the works of Hasok Chang (2001, 2004, 2007; Barwich and Chang 2015) and Bas van Fraassen (2008: Ch. 5; 2009, 2012; see also Padovani 2015, 2017; Michel 2019). These works take a historical and coherentist approach to the problem. Rather than attempting to avoid the problem of circularity completely, as their predecessors did, they set out to show that the circularity is not vicious. Chang argues that constructing a quantity-concept and standardizing its measurement are co-dependent and iterative tasks. Each “epistemic iteration” in the history of standardization respects existing traditions while at the same time correcting them (Chang 2004: Ch. 5). The pre-scientific concept of temperature, for example, was associated with crude and ambiguous methods of ordering objects from hot to cold. Thermoscopes, and eventually thermometers, helped modify the original concept and made it more precise. With each such iteration the quantity concept was re-coordinated to a more stable set of standards, which in turn allowed theoretical predictions to be tested more precisely, facilitating the subsequent development of theory and the construction of more stable standards, and so on.
