Rosen’s Path to Rosen Closure Functional System (RCSF)
Rosen’s Path to Rosen Closure Functional System (RCSF) Breaking from General Systems Theory 1.1 Interaction models and their limits 1.2 Why organization is insufficient without causal entailment 1.3 Rosen’s move from open systems to closure Rosen’s Foundational Shift: Closure to Efficient Causation 2.1 The (M,R)-system 2.2 Self-production vs external functional assignment 2.3 Closure as the minimum condition for persistence Category Theory as the First Formal Home 3.1 Why Rosen needed categorical language 3.2 Cartesian closed categories and reflexive objects 3.3 Fixed points, entailment loops, and self-reference 3.4 Why category theory gives structure before dynamics From Abstract Closure to Structural Forcing 4.1 Closure as a constraint, not a metaphor 4.2 Elimination of arbitrary components 4.3 From descriptive systems theory to necessity Autopoiesis as the Embodied Subclass 5.1 Maturana–Varela and organizational closure 5.2 Boundary production and material realization 5.3 Why ...
