II: A New Approach and
its Problems
I agree, accordingly,
with Chalmers (1995, p. 204) and others (McGinn, 1991, pp. 2, 104; Nagel,
1986, pp. 8-10; Searle, 1992, pp. 26, 49) that a constructive solution, if
possible at all, will require a radically new approach. I also agree with
Chalmers with regard to the basic direction that this new approach must
take: while holding to a position that is still recognizably physicalist,
we should “take experience itself as a fundamental feature of the world”
(p. 210). Given this ontological hypothesis (I add), the conceptual
aspect of the mind-body problem could be solved far more readily than most
of the empirical problems.
There is, interestingly
enough, agreement on this point by the philosopher who has most forcibly
declared the problem of consciousness permanently insoluble: McGinn (1991,
p. 28n) has said that, if we could suppose them to have proto-conscious
states, it would be “easy enough to see how neurons could generate
consciousness.”
While not endorsing
this approach himself, McGinn (p. 81) has cited a passage in Kant that
provides a possible starting-point for it. In this passage, Kant (1965,
p. 381/B428) said of the problem of the communion of soul and body:
The difficulty peculiar
to the problem consists . . . in the assumed heterogeneity of the
object of inner sense (the soul) and the objects of the outer senses . .
. . But if we consider that the two kinds of objects thus differ from
each other, not inwardly but only in so far as one appears outwardly to
another, and that what, as thing in itself, underlies the appearances of
matter, perhaps after all may not be so heterogeneous in character, this
difficulty vanishes.
The apparently
insuperable problem would disappear, suggested Kant, if we held that mind
and body are in themselves of the same nature, and that the idea that they
are different in kind results from observing them from different vantage
points: mind from within, matter from without. Whatever the status of
this proposal within Kant’s own thinking, a solution to the mind-body
problem can most likely be found, I propose, by beginning with this basic
idea, while working it out in a way that differs greatly from the
Leibnizian version with which Kant was familiar.
[1]
I have suggested, in
fact, that with such a starting-point a solution to the basic conceptual
problem is relatively easy. Like Chalmers, however, I stress the
“relatively.” The hard problem from this perspective will be twofold.
First, although the
panexperientialist starting-point overcomes what has thus far been
considered the heart of the mind-body problem, it has obviously not been
easy for philosophers and scientists to see why we should adopt that
starting-point.
Second, even when the
basic idea is accepted, it is far from obvious how to work out this idea
in a plausible way (as illustrated by the failure of Leibniz, hardly a
dimwit).
That these are indeed
severe difficulties is shown by the reception panexperientialism (usually
called “panpsychism”) has received thus far. Although some version of it
has been proposed by a number of first-rate philosophical and scientific
minds (such as Leibniz, Fechner, Lotze, Peirce, Bergson, James, Whitehead,
Hartshorne, Sewall Wright and David Bohm), it is scarcely considered in
mainline discussions of the mind-body problem.
Virtually everyone
assumes that we must choose between some version of dualism (including
epiphenomenalism) and some version of materialism. Thanks partly to
Nagel—who believes that some version of panpsychist physicalism must be
true but also suspects it to be “unintelligible” (1979, pp. 181-2, 188-9;
1986, pp. 49-50)—some contemporary philosophers do mention it. But they
usually dismiss it quickly as “implausible” (Seager, 1991, p. 241n),[2]
“extravagant” (McGinn, 1991, p. 2n), or even “outrageous” and “absurd” (McGinn,
1982, pp. 31-2). Panexperientialism clearly has an uphill battle.
In
the remainder of this essay, I will suggest one way of dealing with
panexperientialism’s twofold problem. The next two sections will be
devoted to the first part, namely: why should we suppose the ultimate
units of nature to embody experience and spontaneity? The fifth section
will discuss the failure of dualism and materialism with regard to some
criteria that an acceptable theory should satisfy. In the final section,
I will sketch out a theory that I call “panexperientialist physicalism,”
seeking to show that panexperientialism, at least in this version, is far
less implausible and far more helpful than has generally been supposed.
