Normal social behavior requires that we be able to recognize identities in spite of change. Unless we can do so there can be no human society as we know it.
My dad was the manager at the 45 000-acre ranch but he owned his own 1 200-acre ranch and I owned four cattle that he gave to me when I graduated from grammar school from the eighth grade. And those cows multiplied and he kept track of them for years for me. And that was my herd.
