Amerini is surely correct to claim, along with Aquinas, that there is a sort of numerical identity between the fetus and an adult human being.

also believes that because Aquinas did not recognize a numerical identity between the embryo and the mature human being, he would not necessarily oppose all early abortions, and would perhaps be prepared to make exceptions in cases of rape and incest.
Character, Psychoanalytic Identification, and Numerical Identity, LOUISE BRADDOCK
It is here argued that, in identification, the subject has an "identity-thought," which is a thought about his numerical identity with the figure he identifies with.
In contrast, the potential to produce is the capacity to cause something else, and hence there is no need for numerical identity.
The first of these arguments passes too easily over difficult questions of personal and numerical identity.
Unlike numerical identity theory, narrative theory focuses on character traits, values, and goals, rather than on the problem of persisting though time as a single individual.
Now the English word "same" is ambiguous between numerical identity (as in "This is the same ball that Sandy Koufax threw the last strike with") and qualitative identity (as in "Your car and mine are just the same").
Given the exponential growth of transactions carried out via remote banks, payments for e-trade and, in the near future, m-trade, the need for guaranteeing one's numerical identity is obvious.
3) Although it seems to be possible to understand numerical identity without connecting the numerically identical objects to predicates, such a connection is frequently discussed in two further proposals: (3) some commentators speak of "relative identity," whereby--according to one interpretation--numerical identity and identity of qualities cannot be combined in such a way that one would follow from the other; (4) (4) there is an even stronger, epistemological and ontological meaning which affirms just this inference from the identity of qualities to numerical identity and/or vice versa--the identity of indiscernibles and the indiscernibility of identicals (both principles known as Leibniz's Law (5)).
Instead, "identity" understood as numerical identity seems to allow but not to require a multiplicity of entities or a connection with properties.
