 We will be careful to distinguish these four different kinds of causal claims. Unfortunately, there is no standard terminology to mark the distinction between causal claims likes like 1 &amp; 2 and causal claims like 3 &amp; 4. So let us introduce new conventions. To mark their contrast with variables, call causal relata like droughts, famines, and car crashes (whether type or token) “constants”. Then, let us call the relation which holds between constants causation. A causal claim that relates token constants will be called a claim about token causation. (This is sometimes called singular causation, or actual causation.) A causal claim that relates types of constants will be called a claim about type causation. (This is sometimes called general causation.) On the other hand, the relation which holds between variables (whether type or token) will be called influence. A causal claim that relates token variables will be called a claim about token influence. (Hitchcock 2007a, uses token causal structure for a network of relations of token influence.) A causal claim that relates types of variables will be called a claim about type influence.
