7. Existence / D. Theories of Reality / 9. Vagueness / a. Vagueness of reality
Evans argues (falsely!) that a contradiction follows from treating objects as vague
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
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
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
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
