Opponents of numerically identical re-creation argued that the first existence belonged to a particular time. If the object later exists at another time, they claimed, the change of temporal determination prevents it from being the very same object.
The response asks whether time is part of the individual's essential identity or an external relation that can change. If every temporal relation were built into numerical identity, the same living person would have difficulty remaining the same from one moment to another.
A change of time therefore does not by itself entail a change of individual. Existing earlier and later, and becoming numerically another being, are different judgments.
