object-declaration

Definition

An object-declaration is a statement [footnote2] that an (existing) object is contained in a universe-of-discourse.

In straightforward language, an object-declaration extends a universe-of-discourse with that object, which makes it possible to speak about that object using other objects.

Formally, whenever an object is declared:

Let U be a newly created universe. Let x be an object declared in U. Let y be an object declared in U.

To be even more accurate, we should consider a universe as an “accreting” variable:

Let x be a newly created object. Let U := U extended by x. Let y be a newly created object. Let U := U extended by y.
