7. Existence / D. Theories of Reality / 9. Vagueness / a. Vagueness of reality
Evans argues (falsely!) that a contradiction follows from treating objects as vague [Lowe]
Is it coherent that reality is vague, identities can be vague, and objects can have fuzzy boundaries?
Evans assumes there can be vague identity statements, and that his proof cannot be right [Lewis]
7. Existence / D. Theories of Reality / 9. Vagueness / c. Vagueness as semantic
There clearly are vague identity statements, and Evans's argument has a false conclusion [Lewis]
9. Objects / B. Unity of Objects / 3. Unity Problems / e. Vague objects
If a=b is indeterminate, then a=/=b, and so there cannot be indeterminate identity [Thomasson]
9. Objects / F. Identity among Objects / 6. Identity between Objects
There can't be vague identity; a and b must differ, since a, unlike b, is only vaguely the same as b [PG]
