Between Substances and Processes: Bridging Metaphysical Divides on Fundamentality, Persistence, and Individuation

Since the early 21st century, processualist approaches have gained prominence in analytic metaphysics and the philosophy of science, prompting diverse responses from advocates of substantialism. However, the polarization of the debate between process and substance metaphysics has often led to oversimplifications that obscure the potential for constructive dialogue. This paper argues that these frameworks should not be treated as monolithic systems, but rather analyzed through the lens of specific metaphysical problems—namely, fundamentality, persistence, and individuation. Focusing primarily on process metaphysics, we examine how different interpretations within both traditions conceptualize these issues. Our analysis reveals areas of compatibility as well as points of divergence, indicating that the divide between processualism and substantialism is more nuanced than commonly assumed. We conclude by advocating for a metaphysical approach that allows for the integration of criteria from both frameworks.
