Can two competing conceptual schemes (CSs) both be true? Is truth defined internally to each particular CS?
William
P. Alston [1979] said that it may be “a piece of outrageous
imperialism” to reject the CSs (or Wittgensteinian
“language-games”) of what he called “different spheres of
discourse”. It's easy to find problems with such a tolerant
pluralism because it seems to allow anything to be uttered (even
things against tolerance and liberalism); so long as it belongs to a
particular “discourse” and is (presumably) internally coherent.
Wittgenstein, for example, was particularly keen on religious
language-games.
There's
a problem with religious discourse (or language-games). If a
religion has its own discourse (which may well be self-contained,
internally consistent and coherent), does that automatically mean
that it does (or can) utter truths? Some coherentists will say,
“Yes”. Thus one religion (or quantum physicist!) may say:
Both A and not-A. Or, more
likely, what if one religion says P and another religion says
not-P? (For example,
“God is always one” and “God is three in one”.)
Interestingly
enough Alston gives various – acceptable? - examples of alternative
discourses. They include “common sense talk about the physical
environment”; “talk about personal agents”; “moral
discourse”; “religious discourse”; “scientific theorising”;
and “experiential reports”. The problem is that all these
examples are not of a piece. Some are mutually contradictory (or
potentially so). Others aren’t (necessarily) contradictory.
For
example, “common sense talk”, “scientific theorising” and
“experiential reports” needn't always contradict one another.
(They may if you're an elimitivist; though not necessarily if you're
simply some kind of reductionist.)
Here
is Quine squaring two CSs:
“Here we have two competing conceptual schemes, a phenomenalistic one and a physicalist one. Which should prevail? Each has its own advantages…Each, I suggest, deserves to be developed. Each may be said, indeed, to be more fundamental, though in different senses: the one is epistemologically, the other physically, fundamental.”[1948]
It's
an extremely tricky problem to determine whether or not alternative
CSs contradict one another. Take “common sense talk” and
“scientific theorising”. (It must be remembered that the former
sometimes includes bits of the latter.) This example is indeed
problematic. Of course certain examples of “religious discourse”
clash violently with “scientific theorising”. Sometimes (or many
times) certain examples of religious discourse clash with “common
sense talk” too. Indeed quantum-physics talk and certain examples
of “religious discourse” are of a piece when it comes to “common
sense talk”: they both often clash with common sense.
We
can, however, be liberal and tolerant – though only up to a point.
For
example, there are no immediate problems with Nelson Goodman’s
position in this intelligent passage:
“…many different world-versions are of independent interest and importance, without any requirement or presumption of reducibility to a single base. The pluralist, far from being anti-scientific, accepts the sciences at full value. His typical adversary is the monopolistic materialist or physicalist who maintains that one system, physics, is pre-eminent and all-inclusive, such that every other version must eventually be reduced to it or rejected as false or meaningless…The pluralists’ acceptance of versions other than physics implies no relaxation of rigor but a recognition that standards different from yet no less exacting than those plied in science are appropriate for appraising what is conveyed in perceptual or pictorial or literary versions.” [1978]
Elsewhere
Goodman says that “we should take seriously the metaphors that
artists use to restructure our worlds”.
However,
Goodman wasn't saying that “anything goes”. He wasn't taking a
position similar to Paul Feyerabend’s. (Did Feyerabend think that
fascism goes?) Goodman was a mitigated pluralist. Indeed
Goodman himself would have accepted reductionism within certain
limits.
Thus
artists can be physicalists too. And Goodmanian pluralism needn't –
and didn't – countenance Feyerabend’s voodoo or Alston’s
Wittgensteinian position on religion.
There’s
a further problem with Wittgensteinian liberalism towards CSs. It
means that there can be no scientific criticism (even after taking on
board Goodman’s animadversions against “monopolistic
materialism”) of religious language-games (or any language-games
for that matter). No philosophical criticism either. Religion, or
voodoo, is let off the hook. The Wittgensteinian view (taken further,
perhaps, by Peter Winch and D.Z.
Phillips) leaves all language-games beyond criticism not only
from science, but from logic and philosophy too. That will be because
nearly all such criticisms will evidently be coming from domains
outside the religious language- games themselves.
Surely
this is far too convenient. What if truth is truth in all
domains and actually transcends them? What if truth doesn’t change
its aspect simply because it's internal to different CSs?
Can
a mystic, therefore, come along and say the following? -
On my view (derived from Wittgenstein), which is wide, coherent and consistent, cats are made of cheese.
This
is why many people still admire and sympathise with the spirit
(though not every letter) of logical positivism (as did Quine).
Again,
we can accept different CSs (even competing CSs) as long as we aren’t
too liberal and look out for contradictions between them. Putnam
himself writes:
“…what is in one sense the ‘same’ world…can be described as consisting of ‘tables and chairs’…in one version and as consisting of space-time regions, particles and fields, etc. in other versions.” [1987]
Here’s
Goodman again:
“Consider…the statement ‘The sun always moves’ and ‘The sun never moves’ which, though equally true, are at odds with each other…Rather, we are inclined to regard the two strings of words not as complete statements with truth-values of their own but as elliptical for some such statements as ‘Under frame of reference A, the sun always moves’ and ‘Under frame of reference B, the sun never moves’ – statements that may both be true of the same world.
“…If I ask about the world, you can offer to tell me how it is under one or more frames of reference; but if I insist that you tell me how it is apart from all frames, what can you say?…” [1979]
Having
sympathised with Nelson Goodman earlier, I’m not altogether happy
with his position above.
For
example, we could simply ask whether we're talking about the sun
itself (and its movements) or the “frames of reference”. When we
talk about one, we're not talking about the other. The sun always
moves regardless of frames of reference. However, according to “frame
of reference B” it “never moves”. This isn't to say that we can
escape from “frames of reference” or “modes of presentation”
(or even Fregean "senses"); though a distinction can be
made nevertheless.
There
are also simple cases of mutually-supporting “frames of reference”.
For
example, with the naked eye we obviously can’t see particles or
fields. With the naked mind we don’t talk about “space-time
regions”. Within another CS we do observe particles with scientific
equipment and so too with fields (if they are actually observed and
aren't "posits"). With a scientific hat on, we talk of
“space-time regions”. There’s no problem here, unless one is an
elimitivist of some kind.
Alston
himself does give an account of what may be incompatible
language-games (or CSs); unlike the examples cited earlier which he
thought are mutually autonomous. He wrote:
“The ontologies of different language-games do not all fit into any single scheme. There is no place in physical space for minds, sense-data, or God. Agency cannot be located in the interstices of the physiological causal network.” [1979]
In
the above Alston appears to be saying that some CSs are wrong/false -
or at least potentially wrong/false. Contrary to the views of Peter
Winch and D. Z. Phillips, these CSs don't – or can't – exist in
splendid isolation. They contradict each other. Eliminative
materialists, for example, deny the existence of propositional
attitudes. Therefore eliminative materialism is at war with folk
psychology. Atheists deny the existence of God. Davidson denied
sensory data. Some determinists reject Alston’s “agency”. And
so on. Things aren’t, after all, so cosy.
Liberalism
and pluralism have their limits. Few of us are pure liberals. Many of
us are mitigated liberals (or mitigated pluralists).
So
whereas Alston showed us his pluralism earlier on, he now shows us
the limits of his own pluralism and tolerance. Thus if he can have
his limits, other people can have their limits too. Consequently, the
limits of other people may include limits on Alston’s pluralism
(e.g. towards “religious discourse”); whereas Alston himself
hints at the unacceptability of certain CSs (e.g. determinism,
eliminative materialism, relativism, etc.).
Thus
with all these limitations (from Alston and from everyone else), why
talk about the “outrageous imperialism” of those who have a
strong problem with certain CSs? After all, Alston also has a strong
problem with certain CSs. So too, ironically, do conceptual
relativists.
Let's
go into a little detail here.
Relativists
do indeed criticise other CSs.
For
example, they don’t have much time for what they call “scientism”
and “physicalism”. Yet according to their own standards, they
aren't allowed to criticise alternative CSs. Scientism and
materialism may be examples of CSs according to which the notion of
truth is defined internally. They may be fairly self-contained or
enclosed universes. Thus how can another CS criticise them if that
very CS (i.e., relativism) is committed to the autonomy of even
contradictory CSs? The conceptual relativist (or plain relativist)
who appears (on the surface) to be committed to the autonomy of CSs
(or language-games), must himself transcend his own CS and therefore
take a bird’s-eye view of “scientism”, etc. - and he doesn’t
like what he sees. Thus why should the fictional bogeyman - the
Scientistic Philosopher - accept the relativist’s criticisms if,
according to the relativist's own CS, truth isn't external to
CSs? We could even say that the relativist is adopting an almost
Nagelian metaphysical realism, without realising that he’s digging
his own grave by doing so.
When
we push absolute pluralists (towards CSs) far enough we always find
their limits.
Pluralism
is either self-defeating or self-contradictory. Just as in politics,
pluralists can't tolerate anti-pluralists and mustn't be tolerant to
the intolerant. Another way of putting this is that pluralism isn't
(or shouldn't be) an absolute.
The
more we analyse the reality of CS pluralism and tolerance the more we
see that it doesn’t in fact exist. Therefore tolerance and
pluralism may not be the virtues they seemed to be. Of course we're
not talking politics here. In politics, pluralism and tolerance may
indeed be commendable. However, an eliminativist, say, won't use his
fists to enforce his CS on those who use, say, religious discourse.
Thus the parallel with politics isn't entirely valid. Tolerance and
pluralism in politics may be virtuous; whereas in philosophy they may
be vices.
Thus
William P. Alston's talk of “outrageous imperialism” (outside
the domain of politics) may be misplaced. It may even be a Rylian
“category mistake”.
