Herds on the streets of Paris. As I was preparing this post, sorting through the photos I have, I started thinking about what constitutes a herd and what doesn’t. A herd, I decided, is a group of similar objects that have chosen to gather together. (Or their respective owners have chosen to gather them together, as the objects lack agency.) This excludes merchandise for sale (one common owner; a herd represents compound decisions) and things that operate as indivisible objects (a metro train can be thought of as a herd of cars, but properly the train, while divisible, is an indivisible object—it needs all five cars to operate) and short-term high-turnover clusters of objects (buses arriving and leaving—there is something static to a herd.)


These photos, on the other hand, show proper herds: Static groups of diffuse, divisible objects that have clustered together through the actions of disparate owners. The motorcycles are an exemplar of the proper herd; these herds of police and medical vehicles are a little harder to define. If the place they gather is formally set, and not ad hoc as the motorcycles’ is, do they still constitute a herd? I would argue they do: Much as herds of animals can cluster out in the field, they can also cluster inside a defined corral. The motorcycles in this example are “out in the wild”—away from their respective home bases—and the emergency vehicles are “in the corral”.


The definition of a herd also assumes a lack of purpose and agency: A farmers’ market isn’t really a herd of humans, because the farmers have chosen to gather themselves there with an explicit purpose. These herds just are—waiting, in most cases, for their owners to return or for them to be pressed into use. The point of a herd is that it is inactive, that when active it is necessarily diffuse
