Abstract
This chapter explores whether causation is a relation between things, like being next to or being taller than, or it is something else entirely. It considers two ways of thinking about causation. The chapter considers it as a real relation, the relation of causal connection, between things or events, or as a logical relation, the relation of causal explanation, among truths. For metaphysicians, the crucial question is whether causal connection or causal explanation is more fundamental. There are two major objections to all three versions of Causal Explanationism: the problem of causal linkage and the problem of the direction or asymmetry of causation. Causal Connectionists posit a category of thing, events (or states or conditions), members of which stand in the fundamental relation of causation. The weightiest objection to Causal Connectionism concerns the phenomenon of negative causation. Causal Connectionism entails that causation is always a matter of some real relation between things.
