The curatorial context in which an entity exists offers an observable spectrum of practical external relationships.
Just as any other entity in art* an Object demands to be related to as what it is in order that it be the thing it is. (The ways curatorial practices are applied to works explicate their implications. If <=> then)
Because with contemporary art curatorial practices have become a casuistry (case law) we are able to observe: 1/ An entity curatorial practices relate to is an agent in these relations. It regulates these practices as an agent in distributed cognition and in a coordinated collective of humans and non humans. 2/ An entity exists and emerges in reciprocal causation with an environment (topological field) it selects in relating to it.

* Most non-object art is curated as any other object. That’s because the non-object is a new object. The sameness that specifies it as an object (as the same from a time to another, from a place to another or from a person to another) has gone from static physical invariance to processual invariance (recursion). Process based objects can be seen as having attractors and variable degrees of freedom.
