Subjectivity: mind, self and soul

I am a spiritual personalist and I agree with this excellent article by Titus Rivas:

Rebirth and Personal identity: Is Reincarnation an Intrinsically Impersonal Concept?

A third type of substantialism amounts to the theory that there is a plurality of ultimately irreducible individual souls rather than just a single divine one. There is a personal conscious subject, self or "I" who sees, thinks, feels, wants, etc. The physical body is not part of the real person in this spiritual sense and personal identity of the personal self cannot be affected by bodily death.

It is important to note that a personal self should be conceptually distinguished from its personality. A personality may be seen as an acquired (existential) pattern of psychological structures, attitudes and skills of a substantial personal self, which (essentially) always remains identical to itself.

In the context of reincarnation we will expect certain changes of personality through the processes of death, rebirth and childhood, but this does not mean those changes imply a new or different personal self. We would remain ourselves just as much as we remain ourselves in the course of a single earthly lifetime.
