In this article, I propose a middle way between current process and substance theorizing as I argue that both ‘pure’ views are fraught with theoretical problems. I base my proposal on the ontologies of Aristotle and A.N. Whitehead, who both maintain that being and becoming are equally important for a comprehensive analysis of change processes. Drawing on their insights, I develop a conceptual frame that distinguishes between change and becoming, and proposes to use the pairs of potentiality-actuality and activity-relationality as notions that are less fraught with conceptual baggage and more relevant empirically than the distinction between substance and process.
