Write-up1 (as at 03/07/2026 09:40:19): Psychological Continuity
Plug Note2
- Thesis Text:
- Like any persisting thing, the persistence3 of a psychology requires continuity to an appropriate degree of the entity supposedly persisting: hence ‘psychological continuity’.
- I’m not quite sure what ‘a psychology’ is supposed to be, but it is supposedly constitutive of personal identity for those accepting the Psychological View4
- Popularly, we say that an individual is ‘not the same person’ as they were before if their character or aims differ too much from that former state. Hence, such characteristics would seem to be constitutive of a psychology.
- It is usual for someone’s character to develop gradually over time, often in a positive sense, though there may be Dorian Grey like declensions. However, there can also be sudden changes, as when someone has a religious or political conversion experience, though – even there – there is continuity of more general psychological factors.
- We are comfortable with gradual changes – new memories are added and lost gradually, and tastes stay fairly constant; knowledge is acquired gradually. But, over time, these gradual changes accumulate to the degree that one might not recognise the child in the adult, say. But usually, we allow that such gradual changes are identity-preserving, even though psychological connectedness5 is to some degree lost.
- All this is associated with one’s First Person Perspective6 (FPP), one’s window on the world7 from which standpoint one anticipates the future, enjoys the present, and remembers the past.
- So, psychological continuity (and connectedness8) is central to personal identity for those who adopt the Psychological View9. However, it is said by some animalists10 - Eric Olson in particular – to be irrelevant to our survival11, given that we are12 Human Animals13.
- Following on from discussions on survival14, maybe the way to put things is that without psychological continuity I might survive, but not with what matters15 to me in survival.
- If “Person16” is a phase sortal17 of “Human Animal18”, can there be sequential but different persons within the same animal (as Lewis19 suggests, though not from the perspective of animalism20, in his “Methuselah21” case) or can there be different and encapsulated First Person Perspectives22 (either synchronically – as in MPD23 – or diachronically) within the same animal?
- “Person” may indeed come apart from “animal”, but even then, the person cannot “float free” of the animal, but supervenes24 upon it. See the CV25 for this.
- I also distinguish between backward and forward psychological continuity26. The former – traditionally involving memory27 and psychological traits – is the usual focus, but it is not necessarily identity-preserving even for those espousing the PV28, on account of reduplication objections29. The same may be true of fission30 of the FPP31, but this is more difficult to imagine.

Footnote 7:
- Note, however, that for Lynne Rudder Baker the FPP is bound to her concept of a Person. The ‘P’ is ontological rather than merely grammatical.
- So, for her, non-persons may have a window on the world, but not a FPP.
