This article gives an overview of the most characteristic steps of the relational modeling strategy, from the component to augmented abstract block diagrams, putting the emphasis on some epistemological aspects. Robert Rosen's modeling strategy is a formal representation of biological organization, specifically of circular causality. In this regard, the most important contribution of Robert Rosen is the anschaulichkeit - the intuitability - of the closure of the organization and of the intertwinement of the different Aristotelian causes, even if they are incommensurable.

In his commentary on Poe's 'The purloined letter' he tries to show that the sequence of signifiers is not arbitrary but governed by an internal logic. In 'Subversion du sujet et dialectique du désir' he tries to show how this chain of signifiers is constituted in a double movement : on the one hand there is the linear succession of signifiers, on the other hand there is an anticipatory movement. We would like to combine these two lines of thought and illustrate this double determination with Freud's case study of the Ratman.

For resolving this problem, we introduced a game modeling characteristics of organizations, inspired by well-known ecoromist K. J. Arrow in "The Limits of Organization". In this game, each agent gives a mandate to an adviser about his right for decision-making. He tells the adviser his fragments of an anticipation about cooperative acts. The advisers decide act of the agents who gave the mandate to him. The agents get a reward that was calculated by a distance from an optimal act. We used genetic algorithm for dynamics of this game. The network structures of delivering mandates between agents have evolved through three phases : 1) disconnected phase 2) connected phase 3) hub agent phase. Finally, we briefly discussed more abstract model that relates to anticipatory system formulation.

The foundations of the theory are developed from observations on the nonlinear dynamics of organisms within ecoments -- ecoments being defined as the immediate surroundings of one hierarchical degree of an emergent system. Each system (sub-system, sub-sub-system ... ) is assigned four primitives attributes (closure, conformation, concatenation and cyclicity) which are subject to scaling and semiotic constraints. In principle, each of these four terms is enumerable for a local system. Degrees of organization (symbolized as Oo) are composed from lesser organized systems to higher organized systems in terms of the enumeration of the four primitives. The emergent organizations are enumerated: 1,2,3, ... The patterns of organization at any particular level, Oo, are composed from patterns at other levels. Thus, no particular science or philosophy is assigned a privileged role in the unfolding of the dynamics. Mathematically, the organized systems are composed under the scientific representations of categories as developed in Chandler, 1991, and Ehresmann and Vanbremeersch 1987, 1997. Categorical objects have the unique mathematical characteristic of creating a 'logical shell' for other classes of mathematical structures. (see S. Mac Lane, Mathematics, Form and Structure, 1986.) This 'logical shell' character of category theory is used here to construct hierarchical relationships between scientific observations and mathematical structures. This notation parallels natural history and allows the facile accounting of the molecular biological mechanisms within a living system. Implications of this theory of natural organization for the design of artifrcial hierarchical systems arc apparent.
