 Yet other philosophers argue that causation is best regarded as a relation between types of events that must be invoked to provide sufficiently general explanations of behavior (Antony and Levine 1997, Burge 1997, Baker 1997). Though many who are moved by the exclusion problem (e.g. Kim, Jackson) maintain that there is a difference between generalizations that are truly causal and those that contribute in some other (merely epistemic) way to our understanding of the world, theorists who advocate this response to the problem charge that this objection, once again, depends on a restrictive view of causation that would rule out too much.
