Abstract

The Stoics’ guiding principle in ontology is the Eleatic principle. Their existents are bodies that have the power to act and be acted upon. They account both for the constitution of material objects and the causal interactions among them in terms of such dynamic bodies. Blending is the physical mechanism that explains both constitution and causation; and is facilitated by the fact that for the Stoics all bodies exist as unlimited divided. In this paper I offer a novel analysis of this Stoic stance, and of the role it plays in their metaphysics. I argue that when blended, the substances involved become sharing subjects of qualities and structural features.
