I believe that the first concept the intelligent mind develops is that of “the thing”. In the chapter on information vectors, the document indicates that information vectors have boundaries in time and space. These boundaries define the scope of a “thing”. The term is used in a general sense: a “thing” refers to any site, sound, event, that can be recognized or identified. So the perception of information vector overlaps with the concept of a thing. Putting it simply, the intelligent mind needs to build the concept of a thing in order to recognize and evaluate the items in its universe.
