Full Idea
When Leibniz has the grounds of de re counterfactuals in mind, a counterpart picture, we have argued, is at work.
Gist of Idea
Leibniz has a counterpart view of de re counterfactuals

A Reaction
If Leibniz were a 'superessentialist', then individuals would be totally worldbound (because their relations would be essential). Cover/Hawthorne argue that he is just a 'strong' essentialist, allowing possible counterparts. Quite persuasive.
