For any objects, it is traditionally assumed that that either the objects are identical or distinct, and not both. Vague identity is a view that rejects this absoluteness of identity. Its proponents claim that it is possible that it be vague whether or not some objects are identical. Some discussions run this together with Parsons' view that it is possible it be indeterminate whether or not objects are identical.

`is an integer greater than thirty' has sharp boundaries, has no borderline cases, and is not susceptible to sorites paradoxes.

I don't know the exact relation between vagueness and vague identity

I am wondering if "vague identity" means "can appear in a vague identity statement" (I don't have access to enough material to decide).

If so, can only precise things be "an integer greater than thirty", so that not everything has a vague identity?

Does that mean not everything is vague?

  • We (human persons) know who we are: our identity is also "social": records, bank account, etc. Philosophers like to be "hyper-skeptical": whatever cannot be "proved" with 100% certainty, must be discarded: but they forget that 1005 certainty is simply meaningless: every proof (also mathematical ones) has a lot of previous assumptions.

  • yes human persons love to be evasive @MauroALLEGRANZA who cares
