Full Idea
Lewis gives an account of causation in terms of counterfactual conditionals (roughly, an event c causes an event e iff if c had not happened then e would not have happened either).
Clarification
'Counterfactuals' are statements beginning "If.." - events that might have happened, but didn't
Gist of Idea
An event causes another just if the second event would not have happened without the first

A Reaction
This feels wrong to me. It is a version of Humean constant conjunction, but counterfactuals are too much a feature of our minds, and not sufficiently a feature of the world, to do this job. Tricky.
