PERSONAL IDENTITY
IN
CHARLES HARTSHORNE'S METAPHYSICS
Santiago Sia
(Carlow College, Carlow, Ireland)
According to Hartshorne, any changing yet enduring
thing has two aspects: the aspect of identity (what is common to the thing in
its earlier and later stages) and the aspect of novelty. A being which changes
through all time has an identical aspect which is exempt from change. It is in
this sense immutable. However, this unchanging identity should not be confused
with a substantial soul. For Hartshorne, personal identity is an abstract
aspect. He writes: "The same-self ego is an abstraction from concrete
realities, not itself a concrete reality."[i]
This is not to say that it is unreal, but it is real within something richer in
determination than itself. Hartshorne explains that the T spoken by me is
distinct from the T uttered by someone else because there is a different
referent of the pronoun in each case. In the same, though subtler, way the T
which I say now has a different referent from the T which I uttered earlier.
The reason for the difference is that the pronoun T (or any of the personal
pronouns) is a demonstrative and is context-dependent or token-reflexive; that
is, the meaning changes each time it is used. There is, of course, an enduring
individuality or a specific subject with definitive experiences. But each new
experience which the subject undergoes means a new actuality for that subject.
The persistent identity itself is abstract while the actual subject having
these experiences is concrete. Thus, there is a new I every moment and the T
really means not just 'I as subject here' but also 'I now'.
In short, spatial and temporal considerations are
intrinsic to one's concrete reality. The concreteness of the subject is due to
the society or sequence of experiences of which the subject is composed. The
referent of T is usually some limited part of that sequence of experiences. As
Hartshorne puts it, "Personal identity is a partial, not complete,
identity: it is an abstract aspect of life, not life in its concreteness."[ii] This is why it would be erroneous to
hold that each of us is always simply the same subject or the same reality even
if we must admit that we are the same individuals. We are identical through
life as human individuals, but not so in our concreteness. Concretely, there is
a new man or woman each moment. To recognize the sameness of that man or woman,
we must disregard that which is new at each moment.
Hartshorne furthermore differentiates personal
identity from strict identity. Identity in its strict meaning connotes entire
sameness, total non-difference, in what is said to be identical. If x is
identical with y, then 'x' and 'y' are two symbols but with one referent. The
difference between them is only the symbols or the act of symbolization, not in
the thing symbolized. It follows that x does not have any property which y does
not have and vice versa. Personal identity, on the other hand, is literally
partial identity and therefore partial non-identity, the non-identity referring
to the complete reality while the identity to a mere constituent. Personal
identity is the persistence of certain defining characteristics in a very
complex reality which constantly changes.[iii]
Peter Bertocci agrees with Hartshorne that
identity is never a strictly logical identity as attested by personal
experience since one is self-identifying unity-continuity in change.
Nevertheless, he has reservations over Hartshorne's statement that
"reality is the succession of units" (i.e., actual entities or
experient occasions). In Bertocci's view, this statement cannot be rendered
coherent with personal self-conscious experience. Instead he argues that he
experiences himself as a unity, a self-identifying continuant who can recognise
and recall his own experiences as successive. He writes, "There is nothing
in my synthesis of successive moments. I am indeed active in any moment, but I
am neither a collection of moments nor a "synthesis".[iv]
Bertocci is voicing a basic episte-mological and ontological disagreement. He
questions the validity of Hartshorne's doctrine that the present contains the
past — this doctrine, it was noted, complements Hartshorne's interpretation of
human immortality and forms the basis for his version of personal identity
-because there does not seem to be an experiential basis for this. Simply put,
the past does not come into the present for it is gone forever. When it comes
to personal identity, therefore, one cannot say that one is in one's past, but
only in one's present. "The burning, present experience is a present
complex unity that is able to identify itself as changing and successive... In
a present [experience] I recognize aspects I describe as past, but my present
is never an accumulation of pasts (hidden, distinct, or clear)."[v]
In short, Bertocci claims that one knows the past but this does not mean that
the past itself exists.
Bertocci, it would appear, is equating experience
with the substance theory. He himself wonders whether his present uneasiness
with Hartshorne's theory is due to an obstinate residue of the psycho-logic of
substantive metaphysics. In this respect, one could indeed ask whether Bertocci
is justified in regarding the substantive theory as our experience of personal
identity. After all, many others, notably the Buddhists, would have a different
interpretation of their sense of personal identity. One suspects that the
Western mind has been shaped mainly by Greek conceptions which makes it easy
for some Westerners to accept them as indeed their experience. Robert Neville does
acknowledge this point. In his criticism of Hartshorne's account of continuity,
Neville writes that Hartshorne's event pluralism which is intended to account
for continuity does not articulate "the Western's sense of individual
continuity".[vi]
Both critics accuse Hartshorne's theory of not having a basis in experience.
What is surprising about their criticism is that some have rejected the
substance theory precisely because it does not seem to square with personal
experience. The Buddha had rejected the Hindu doctrine of Self (although this
is not the same as the substantial self) because he could only experience
momentary, transitory states, which he regarded as constituting 'the self.
David Hume was critical of the classical notion of 'soul' since according to
him there was nothing in our experience to support it. The point at issue here
is: which aspects of our experience can justifiably serve as the basis for
philosophical thinking? The more crucial question then is: what exactly do we
mean by experiencing ourselves as subjects? The answer to that question will
shape our response to Hartshorne's theory of personal identity.
Henson is of the opinion that Hartshorne has not
really explored the possibility of a notion of self-identity that is not the
same as the substantial self that he is critical of. He claims that Hartshorne
"seems to be in danger of making selfhood, a concrete dimension of
experienced reality, into an empty — hence unreal - abstraction".[vii]
Henson's question as to whether one cannot uphold a third alternative to the
classical notion and to Hartshorne's interpretation of personal identity
remains.
