||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. Opponents argue that a vague or indeterminate identity relation violates Leibniz's Law because there is a property that one object has and the other lacks (for example, a case where an object a has the property indeterminately identical to b, while object b does not). The objection continues that any relation violating Leibniz's Law cannot be the identity relation.
