Full Idea
Hobbes implies that a Kim-style event e1 existing at t1 cannot possibly act on an effect e2 at t2, because that effect does not exist until the Agent has worked its effect on the Patient to provoke a change, thus bringing the effect into existence.
Gist of Idea
One effect cannot act on a second effect in causation, because the second doesn't yet exist

A Reaction
[Hobbes Elements of Phil 1656 II.IX.1] Ingthorsson says that the Hobbes view is the traditional 'standard' view, that objects (and not events) are the causal relata. A strong objection to events as the causal relata. Realists need objects.
