  The same kind of story can be applied to the cloud. It is because the cloud is a more natural object than the region of space time a mile above the cloud that our demonstrative ‘that’ denotes the cloud and not the region. However, none of the oi are more natural than any other, so there is still no fact of the matter as to whether ‘that’ picks out oj or ok. Lewis's theory does not eliminate all semantic indeterminacy; when there are equally natural candidates to be the denotation of a term, and each of them is consistent with our dispositions to use the term, then the denotation of the term is simply indeterminate between those candidates.
