Abstract
If an ordinary object causes an event, and if its atoms acting in concert cause the
same event, then the event in question is overdetermined by two independent causes. The
overdetermination argument aims to show that effects are never overdetermined in this way, and
that we should only admit that the atoms acting in concert are the cause of the event in question.
This means that the object constituted by those atoms does not cause anything, and if this is so,
then the object does not exist. I submit that it is possible to resist the overdetermination argument
by claiming that causation is strictly an event-event relation. However, the argument can be
reformulated in a way that blocks this objection. I explain how the reformulated version of the
argument can be resisted by claiming that there is only one causal event that is undergone by
both the object and its atoms acting in concert. Additionally, I show how the epistemic argument
that can be formulated in support of the overdetermination argument can be resisted as well.
