Thoroughly enjoyable read by a master author. Laid out as a kind of travel diary rather than a work of academic scholarship, Truth Spots is highly accessible to readers of all stripes, not just academics or students. There is a flip side to that coin though. References and debts to previous scholarship are not absent in the book, they’re just obscured and non-explicit. Somewhat paradoxically, this makes Truth Spots a rather hard read for someone looking to make scholarly use of it. Rather than explicitly positioning himself among existing scholarship on, say, labs or courtrooms, Gieryn writes more or less as if he had gotten his ideas from thin air and then happened to find some interesting writing on similar topics. This has the effect that, in order to assess Gieryn’s position in the scholarly conversations he engages in, the reader has to be extraordinarily well-versed in them, much more so than if the book had been written as a standard academic monograph.
