Single Idea 12155
[filed under theme 9. Objects / F. Identity among Objects / 3. Relative Identity
]
Full Idea
Statements of 'relative' identity are not identity statements at all, but what I would prefer to call 'statements of resemblance' or 'common property staztements'.
Gist of Idea
Statements of 'relative identity' are really statements of resemblance

A Reaction
This seems like a neat way to sweep the problem from our sight. There remains a nervous metaphysical problem, though, because something seems to be identical when we spot a resemblance. Even two shades of red have something identical in them.
