There is a peculiar instability at the centre of every claim that a new field of knowledge has emerged, because the evidence most frequently offered in support of such a claim is also the evidence that most readily undermines it: the production of a distinctive vocabulary. New terms are easy to coin, proliferate rapidly, and can generate an appearance of intellectual territory long before any actual territory has been secured. A vocabulary may therefore indicate conceptual invention, but it may equally signal nothing more than the persistence, ambition, or stylistic consistency of an individual author. The decisive question is not whether a body of work has generated names, but under what conditions those names cease to function as ornaments and begin to operate as load-bearing distinctions: distinctions whose removal would diminish the capacity to identify, compare, organise, or intervene in phenomena that otherwise remain blurred. Socioplastics is significant because it places itself inside this difficulty rather than pretending to have resolved it in advance.
