Single Idea 15536

[filed under theme 9. Objects / B. Unity of Objects / 3. Unity Problems / e. Vague objects ]

Full Idea

Many surfaces are equally good candidates to be boundaries of a cloud; therefore many aggregates of droplets are equally good candidates to be the cloud. How is it that we have just one cloud? And yet we do. This is Unger's (1980) 'problem of the many'.

Gist of Idea

We have one cloud, but many possible boundaries and aggregates for it

A Reaction

This is the problem of vague objects, as opposed to the problem of vague predicates, or the problem of vague truths, or the problem of vague prepositions (like 'towards').
