[catalogued under 10. Modality / E. Possible worlds / 3. Transworld Objects / a. Transworld identity]

Full Idea

The Theory of Worldbound Individuals contends that no object exists in more than one possible world; this implies the outrageous view that - taking properties in the broadest sense - no object could have lacked any property that it in fact has.

Gist of Idea

If individuals can only exist in one world, then they can never lack any of their properties

A Reaction

Leibniz is the best known exponent of this 'outrageous view', though Plantinga shows that Lewis may be seen in the same light, since only counterparts are found in possible worlds, not the real thing. The Theory does seem wrong.
