Abstract

This special issue explores both the metaphysical and theological significance of “middle-sized things” — everyday objects, persons, and sacraments — in light of developments in contemporary science and philosophy. Against prevailing neo-Humean and microphysicalist backdrops, where only microphysical entities are taken as fundamental, contributors interrogate the ontological reality and causal powers of the macroscopic domain through engagements with quantum physics, biology, the metaphysics of substance, and sacramental theology. Essays range from arguments for Aristotelian hylomorphism and critiques of reductionism to narrative theories of identity and teleological accounts of divine action. Together, they examine whether middle-sized entities can be causally efficacious, metaphysically basic, and theologically significant.
