As people change, are they still the same person, or philosophically are they someone else?

Put another way, is personhood defined by space and time as well as matter?


Question inspired by my 4 y/o son who after 2 years apart, is convinced his old friend isn't his friend. He's someone else.

If you define people by static snapshots of their personas over time, they are different people than they used to be

If you define people in terms of their lives’ trajectories, then you accept that change is a constant whose magnitude and direction make them uniquely who they are. The tension disappears
