Full Idea
There are two main ways of spelling out an 'intrinsic' property: if and only if it is shared by every duplicate of an object, ...and if and only if the object would have this property even if the rest of the universe were removed or disregarded.
Gist of Idea
An 'intrinsic' property is either found in every duplicate, or exists independent of all externals
