Differentiation as the Ontological Condition of Actualization

This article advances an ontological principle: coherent systems achieve determinate reality only through internal acts of differentiation. In the absence of such acts, what appears as a system is merely an undifferentiated substrate—operationally indistinguishable from noise for any potential decoder, a field of potential without structured actuality. Drawing on information theory, quantum mechanics, and systems theory (particularly Luhmann’s operative constructivism), the argument treats differentiation not as a descriptive tool or secondary process, but as the generative condition under which reality, as structured for a system, emerges from substrate. Modeling and observation are thus not mere representations of pre-existing being; they are constitutive of the determinate form of being for the systems that enact them. Keywords: differentiation, modeling, coherent systems, substrate, actuality, information theory, quantum measurement, operative constructivism, observer-dependent reality
