 The best way to show that the core assumptions of the substance paradigm are not laws of thought is to dispense with them while working out philosophical accounts that are anchored in a new research paradigm. Whitehead’s philosophy still is the most comprehensive, systematic, and detailed proposal for such a fundamental theory revision, but, as often remarked upon, the depth of Whitehead’s philosophical revision does not make for easy access. Accordingly, contemporary processists fall essentially into three groups. The first group pursues the task of explicating Whitehead’s philosophy to the philosophical mainstream, e.g., by putting metaphilosophical issues centerstage (Auxier and Herstein  2017).[6]  The second group adopts selected insights or elements of Whitehead’s scheme, partly without attribution, in order to work out, in mainstream terminology, a solution to a specific problem. The third group develops distinctly non-Whiteheadian routes into process philosophy, guided by research in linguistics or new branches and results of science. In the following the focus will be on the third group, with occasional pointers to contributions to the second.
