PD Prideaux is an independent philosopher and the originator of Constraint Theory, a systematic metaphysical framework proposing that constraint is ontologically primitive - that limitation is not an absence of being but its generative condition. On this view, structure, complexity, and meaning do not emerge despite boundaries but because of them.
The foundational paper is Constraint as Ontological Primitive.
The theory has been developed across a range of philosophical domains. A monograph developing the full framework and its applications across these domains is in preparation.
