" (2) a domain of individuals or universe of discourse has to be established and the individuals within that domain are supposed to be capable of being distinguished from each other by means of their condition in that organization or particular handles available to a user of that model. III. The original of a model may itself be physical or conceptual. It may be so, independently of the consistency of the model. The model in the arts for example can be understood as an individual that functions as a proxy for certain aspects of a concept such as man, men, woman, child, etc. or as one of these under particular conditions. The original temporally or causally may be a predecessor of the original or a successor of it depending on the case at hand. Boat Model Navy Often it will be such that historically there can be found an iteration of sequences of model constitution and original constitution. One should not miss out the point that the original as well must be constituted in some way so it becomes accessible to the modeling individual I. "
