Theoretical ecologist Robert Ulanowicz builds on work by Rosen and others to develop a comprehensive "ecological metaphysic". In his book, "Ecology, the Ascendent Perspective", Ulanowicz develops an ecological metaphysic and contrasts it with the older, mechanical Newtonian counterpart. In a 1999 article in the journal, "BioSystems?", Ulanowicz describes the Newtonian paradigm as one which treats systems as 1) deterministic and thus predictable, 2) closed to external influence and well-described with forces, 3) time-reversible, and 4) decomposable, fractionable or atomistic. He adds a 5th descriptor that states that "Newtonian laws are universal." In contrast, the ecological paradigm of systems he has developed treats systems as 1) indeterminate and thus unpredictable, 2) contingent or best described with propensities, 3) historical and time-irreversible, and 4) organic and not readily decomposable. He suggests that laws derived from an ecological metaphysic are "granular", hierarchical and scale-dependent rather than universal.
Rosen and Ulanowicz share the view that an understanding of life is not something readily gained by extension or extrapolation of a mechanical approach to systems. Instead, each has worked to develop a new paradigm that differs from the mechanical paradigm and then has attempted to demonstrate how this new paradigm is better for understanding and explaining the special properties and dynamics that life exhibits. If one were to reverse this process - to ask what implications this new ecological paradigm might have for understanding, conceiving or designing machines - the work of theoretical ecology may hold important insights for human technology and its evolution.
