Laypersons
and even many philosophers say that much of what's discussed and stated in
analytic metaphysics is ridiculous and/or trivial. That may be true.
Though we must have a wider and more historical vision here because
isn't it also the case that this sort of thing has been said
about many historical philosophical positions – both by laypersons
and by philosophers?
Take
the common reaction to Bishop Berkeley's "empirical idealism" (e.g., when Dr
Johnson
kicked the stone). Or the dismay at the seeming truism of Descartes'
Cogito.
And you don't even need to mention Martin Heidegger's “the
nothing nots”
(as translated by Rudolf
Carnap) to elicit
such
responses. So, at least to the layperson, is analytic metaphysics
really that different
to
what's gone before?
Perhaps
we should also say that some old philosophical positions are now so well-known that it's therefore hardly surprising that many
laypersons are no longer shocked or disgusted by them.
On
the other hand, philosophical
disgust at metaphysics goes back to Kant or further. As Craig
Callender
puts it:
“Kant
famously attacked metaphysics as an assortment of empty sophistical
tricks, a kind of perversion of the understanding.”
“Most
of the controversies in traditional metaphysics appeared to me
sterile and useless. When I compared this kind of argumentation with
investigations and discussions in empirical science or [logic], I was
often struck by the vagueness of the concepts used and by the
inconclusive nature of the arguments."
Then
again, so too did the just-mentioned Martin Heidegger – in his What
is Metaphysics? [1929] - at roughly the same time as Carnap.
Not only that: Carnap spoke out against Heidegger's metaphysics –
in his The
Elimination of Metaphysics Through Logical Analysis of Language
[1931] - when Heidegger was himself speaking out against what he classed as “Western
metaphysics”. Thus being against metaphysics – at least in the
1920s, 1930s, 1940s, and 1950s - became both a sport and a philosophical
fashion.
As
stated, many positions within analytic metaphysics (sometimes within
the entire genus
of metaphysics) are deemed by both laypersons and philosophers to be
trivial, scholastic and/or oblivious to science.
This,
for example, is Craig Callender (in his 'Philosophy
of Science and Metaphysics') taking the piss out of analytic
metaphysics:
“...
when I bend my fingers into a first, have I thereby brought a new
object into the world, a fist?”
Despite that, at least according to Callender, such views are nonetheless
deemed to be “deep, interesting, and about the structure of
mind-independent reality” by such metaphysicians.
Other
philosophers have also had a go at analytic metaphysics.
David
Chalmers,
for example, thinks most of the disputes are primarily “verbal”
in nature. Steven
Yablo
(who's written a lot on metaphysics – including about whether the Turin Shroud and the cloth it's made
up of
are two different objects) believes that there are no answers to many
of the issues or disputes raised in analytic metaphysics. (See his
'Must
Existence-Questions have Answers?'.)
Science
When
an analytic metaphysician (or indeed any metaphysician) says that
metaphysics is concerned with problems which aren't (strictly
speaking) scientific (as well as when he says that metaphysics uses analytical, philosophical and logical methods which aren't those of science),
then some philosophers may give the obvious reply:
The
problems, concepts and tools of metaphysics shouldn't be distinct
from science – even if they aren't identical.
Though
if you were to take this position too far, then metaphysics will
simply become
physics/science. Either that or, at the least, it will become a (subsidiary) part of
science/physics.
The
problem is that no only may such anti-metaphysical philosophers throw
out all metaphysics with these demands
(i.e., if you follow their logic to its conclusion), it may also be
the case that much science will be thrown out too. (This point was
famously made against certain positions advanced by the logical
positivists in the 1920s and 1930s.)
For
example, what about empirically-untestable string theory and
multiverses? Are they examples of scientific “neo-Scholasticism”?
What about some of the well-known mathematical and logical problems
which can simply be seen as “intellectual puzzles” and nothing more?
Again,
the major criticism of analytic metaphysicians is that they more or
less ignore science. In at least some cases, metaphysicians do so
because they believe that metaphysics comes
before physics.
(Yes, despite the Greek translation of the word.) Thus it doesn't make
sense to consult science if science (or at least physics) comes after
metaphysics. Nonetheless, Ted Sider (one of the best known analytic
metaphysicians), for example, has a sophisticated view on
metaphysics' relation to science. Put very simply: he doesn't believe
that any metaphysician should ignore science. (However, at least at
face value, that position may not amount to much.)
Indeed
even when metaphysics does square with science (as 4-Dimensionalism,
for example, is said to do), it may still be the case that this just
adds to the cogency and value of the metaphysical theory or position. In other
words, in terms of 4-D again, metaphysics could survive very well
(thank you) without the help of Einstein's theories of relativity. In addition, positions on time in physics and cosmology are also deemed to be
secondary to metaphysics by some analytic metaphysicians. It's even
the case that such metaphysicians go further than that when they argue
that physics and cosmology must be brought into line with
metaphysics, not the other way around!
How
can we respond to this Metaphysics First position?
It
can be said that before the rise of modern science it was indeed
philosophers who investigated “the fundamental structure and nature
of physical reality” (as it's often put). However, after the rise
of modern science, many philosophers now argue that metaphysicians shouldn't still be doing metaphysics without the help or findings of
science.... at least not in 2017!
As
a consequence of all that, such naturalistic philosophers are against what's often called “a
priori metaphysics”
or the search for “a priori truths”.
Prima
facie, however, it's hard to believe that there's a 21st-century
metaphysician who would claim to be engaged in an entirely a
priori pursuit. (Though perhaps I'm wrong.) In fact I'm not even
sure what the words “a priori metaphysics” (i.e., if taken
literally) mean or whether it would be achievable even in principle.
Anyway,
if such a
priori metaphysics
does exist, then the philosophers James Ladyman and Don Ross, for
example, class it as “neo-Scholasticism”.
Thus
I'll now concentrate on their position against analytic metaphysics.
Ladyman
& Ross's Case Against Analytic Metaphysics
Sometimes James Ladyman and Don Ross's (who are self-described “ontic structural
realists”) main criticisms of analytic metaphysics seem a little
rhetorical – at least as they stand. For example, in their book
Everything
Must Go: Metaphysics Naturalized, they argue/state:
i)
That metaphysics "contributes nothing to human knowledge”.
ii)
That metaphysicians are "wasting their talents”.
iii)
That metaphysics “fails to qualify as part of the enlightened
pursuit of objective truth, and should be discontinued”.
It's
also the case that Ladyman and Ross are arguing that metaphysicians
should be scientifically-literate holists who should attempt to show us
“how everything fits together” (as Nelson Goodman once put it).
In
other words, the “ontological structure” of the universe is the
domain of physics and science generally. Metaphysics, on the other
hand, should attempt to find a unified and “cross-disciplinary”
philosophical synthesis of how the sciences tell us the universe/reality is
structured. (Put that way, this is similar to Quine's position; though
he didn't really emphasise cross-disciplinary unification as such.)
Intuitions?
It's
extremely ironic that in view of the counterintuitive positions
advanced in analytic metaphysics that the enemies of such positions
claim that metaphysicians rely too much on what they call
“intuitions”.
I
suppose that there may be a simple answer to that. Namely, intuitive
positions – or intuitive beginnings (as it were) – can take one
in very counterintuitive directions; just as the intuitively-true
premises of logical arguments can take one to extremely
counter-intuitive or even paradoxical conclusions.
In
any case, it's notable how important the criticism of the analytic
metaphysicians' reliance on intuitions is. It's also true that some
philosophers have acknowledged - and then relied upon - intuitions; though
many others haven't.
Having
said all that, it's almost impossible not to begin one's
philosophical pursuits without utilising one's intuitions to some
extent - or even to a large extent. (All this, of course, entirely
depends on the definition of the word 'intuition'.) And it may follow
from this that if one's intuitions are acknowledged as a starting
point, then that starting point is bound to have an affect on much of
what follows (i.e., in terms of reasoning and actual philosophical
conclusions).
On
the other hand, it's also prima facie ironic that
metaphysicians rely at all on intuitions. Isn't it far more
likely that an epistemologist or a philosopher of mind (for reasons I
hope are obvious) would (or even should) stress or rely on
intuitions?
In
any case, there are many arguments in favour of intuitions... and not
all of them use intuitions to defend intuitions.
For
example, you must start from somewhere. And the best - or even the
only - place to start from in philosophy (as in most things) is from
one's own intuitions. Indeed it's hard to even make sense of the idea
of starting from anywhere else. And if you start from your own
intuitions (I stress the word start),
then it may be equally - or more - wise to take on board collective/social (as it were) intuitions too.
Bearing
all that in mind, it's hardly a cardinal
sin if
metaphysicians begin
their reasonings by using phrases such as "it is intuitive that"
or "it is counter-intuitive that" when, presumably, such
philosophers won't end
their philosophical pursuits with such phrases (or, indeed, with a
continued reliance on intuitions).
You
can also defend the existence and utilisation of intuitions without
using the phrase (which I noted in Ladyman and Ross) “the
faculty of intuition”.
That sounds like the kind of reification which Gilbert Ryle warned
against (though he referred to intelligence, will, mental events, etc.) some seventy years ago. Indeed if people do believe in such a
faculty, the it may well take on a role similar to that of Kant's a
priori categories
or even been seen as a module (or part) of the brain. In that case,
just as philosophers could have asked Kant why he thought that the
mind's concepts or categories were a-historical and universal; so a
contemporary critic can ask why (some) metaphysicians think that our
faculty
of intuition
is reliable and/or static from (say) an evolutionary/biological
point of view.
However, our intuitions needn't be seen as a
priori,
a-historical or even as constituting a faculty
as such.
It
would be wise, then, to say that when contemporary metaphysicians
appeal to intuitions, they don't (or, at least, they ought not to)
refer to some magical ability which only they possess.
Others
on Intuitions
If
an “experimental” or “naturalist” philosopher says that
intuitions aren't scientific data, then a metaphysician may simply
say: “Yes, I know. And?”
On
the one hand it may be understandable to argue against intuitions
regarding, say, quantum mechanics, cosmology or the nature of DNA. On
the other hand, many mathematicians and scientists (ranging from Kurt
Gödel and Alan Turing to Roger Penrose) have happily stressed the
importance of intuitions in both mathematics and physics. (Though,
admittedly, perhaps not in quite the same way these guilty
metaphysicians do.)
In
any case, what are now called “experimental philosophers” have a
problem with (much) analytic metaphysics for this reason. As stated,
they believe that they place too much emphasis on intuitions and
their corresponding “thought experiments”. Of course speculation
and even thoughts experiments are of vital importance in science too
– especially in physics. However, experimental philosophers have
something else in mind here. It's not that physical
experiments
are wrong: it's that
thought experiments
are wrong. In physics, speculations are eventually tested via
experiment, observations, etc. This isn't the case when it comes to
metaphysics. In analytic metaphysics, experiments or observations
don't – or may not - make a blind bit of difference. Such
metaphysical theories usually stand or fall regardless of
experiments and even regardless of science taken more generally.
The
other thing is that experimental philosophers are questioning the
intuitions and thought experiments of analytic metaphysicians from a
scientific or experimental point of view. That is, they use the
empirical studies found in psychology and cognitive science to cast
doubt on the efficacy or truth of human intuitions and philosophical
thought experiments. Such empirical research on human subjects
shows them that its very unwise to trust intuitions and what
follows from them.
Of
course metaphysicians and some philosophers aren't too keen on the
views of these new kids on the block – the experimental
philosophers
(such
as Jesse J. Prinz,
etc.).
Timothy
Williamson
(in
his 'Philosphical
intuitions and scepticism about judgement'),
for example, believes that although intuitions can be taken as being
very basic; they can also be - at least in some cases - the end
result of previous high-level reasoning. This must mean that
intuitions are actually the products of implicit/tacit prior knowledge.
(They may also have value from an evolutionary point of view.) Even
the imagination, according to Williamson, is a good guide to reality,
at least if it's used correctly. (Of course Descartes said this
about the mind and reason itself – i.e., if you use your mind and
reason as God intended you to use them, then you can't go wrong.)
In
the senses stated above, then, intuitions aren't really... well,
intuitions at all. These judgements, positions or premises may simply
have the phenomenological feel (as it were) of intuitions. However,
this is also problematic in that it ties seemingly intuitive
judgments, positions or even a priori premises to the
subject's history and perhaps also to his/her sociological position
within that history. Either way, we can ask whether intuitions come
out well after all this.
Kantianism
The
metaphysical realism of (some/all?) analytic metaphysicians (though
it's not necessary for an analytic metaphysician to be a metaphysical
realist) has been challenged since the beginning of philosophy.
Take
the position of John Locke.
John
Locke believed that it may be permanently impossible for us to
ascertain the true nature of the world or reality (i.e., his
“something, I know not what”).
In An
Essay Concerning Human Understanding, Locke
writes:
“…it
is impossible for us to know, that this or that quality or Idea has a
necessary connection with a real Essence, of which we have no Idea at
all, whatever Species that supposed real Essence may be imagined to
constitute.”
That's
also partly why Bishop Berkeley
turned towards empirical idealism; as well as away from scientific
materialism and the scepticism it engendered. In his Three
Dialogues between Hylas and Philonous, Berkeley
wrote:
“....
the whole issue can be allowed to rest on a single question: is it
possible to conceive of a sensible object existing independently of
any perceiver? The challenge seems easy enough at first. All I have
to do is think of something so remote—a tree in the middle of the
forest, perhaps—that no one presently has it in mind. But if I
conceive of this thing, then it is present in my mind as I think of
it, so it is not truly independent of all perception.”
Then
Kant brought noumena into the debate. The Kantian problem of
noumena caused various later philosophers to embrace (Kantian)
transcendental idealism once again – and so did many late 19th-century and early 20th century scientists (e.g., Mach, Helmholtz, Boltzmann, Hertz, early Einstein,
etc.).
A
semi-Kantian position is also offered – here in the 21st century -
by Mauro Dorato. He writes (as
quoted by Ladyman and Ross):
“....
the concept of unobservable entities that are involved in the
structural relations always has some conventional element, and the
reality of the entities is constituted by, or derived from, more and
more relations in which they are involved.”
So
why is this Kantian? Ladyman and Ross (again) write:
“...
an epistemic structural realist may insist in a Kantian spirit...
there being such objects is a necessary condition for our empirical
knowledge of the world.”
This
is a good description of the noumenal grounding of Kant's metaphysics
and indeed his epistemology. You can sum it up with a simple Kantian
question:
If
there are no noumenal objects (which ground our representations,
etc.), then what's it all about?
If
we can now come up to date, Frank Jackson says that “we know next
to nothing about the intrinsic nature of the world”. Indeed we
“know only its causal cum
relational nature”.
Scientific & Metaphysical Structuralism
One
way out of this impasse (of
noumena and the consequent embracing of idealism) is to become some
kind of metaphysical or scientific structuralist. Thus Peter
Unger, for example, argues that “our knowledge of the world is
purely structural”. What's more, Peter Unger adds
that
“things
in themselves [i.e., noumena]... are idle wheels in metaphysics and
the PPC imposes a moratorium on such purely speculative philosophical
toys”.
However,
there is indeed a major philosophical problem with this 21st century "anti-realism"; which may be highlighted by some metaphysical
realists.
Even
if our representations, models, "posited objects", etc.
don't somehow “mirror” - or even represent - nature or
reality (or if we didn't have the noumenal grounding in the first
place), then surely we have precisely nothing. Or as Ladyman and Ross
put it (almost quoting Kant
word-for-word):
“...there
being such objects is a necessary condition for our empirical
knowledge of the world.”
So,
again, we may not mirror nature or things; though we must
capture something. Then again, how can we represent - let
alone mirror - something as strange as Kantian noumena? How would
that work?
This
is when structuralists say:
Yes,
we capture structure.
Yet
that response won't quite work because metaphysical realists believe
they're capturing (if not mirroring) determinate reality. Structuralists may not think that; though structure is real. That's why Ladyman
and Ross, for example, appear to make what can be seen as the obvious
conclusion when they write:
“....
we shall argue that in the light of contemporary physics... that talk
of unknowable intrinsic natures and individuals is idle and has no
justified place in metaphysics. This is the sense in which our view
is eliminative...”
One
can conclude that because we can't get at things and reality in their
pristine metaphysically-realist state: then, if that's a necessary
truth, we may as well say that “structure is all there is”. This
ties in nicely with the structuralist position that Kantian noumena
may as well also drop out of the picture. Or, as Wittgenstein put
it in his
Philosophical Investigations (though about
something else), things or noumena are
“wheels
which can be turned though nothing else moves with them is not part
of the mechanism”.
To
put the case very simply, there's an argument which one can adopt
here:
i)
There are things and a determinate reality, though we can never
access them as they are “in themselves”.
ii)
And if we can't access reality and things as they are in themselves,
then why not drop the notion of a determinate reality completely
from the philosophical picture?
It
can be said that ii) follows from i); though it can't also be said
(strictly speaking) to logically follow from i).
