Ludwig Wittgenstein is one of the most influential philosophers of the
twentieth century, and regarded by some as the most important since Immanuel
Kant. His early work was influenced by that of Arthur Schopenhauer and,
especially, by his teacher Bertrand Russell and by Gottlob Frege, who became
something of a friend. This work culminated in the Tractatus
Logico-Philosophicus, the only philosophy book that Wittgenstein published
during his lifetime. It claimed to solve all the major problems of philosophy and
was held in especially high esteem by the anti-metaphysical logical
positivists. The Tractatus is based on the idea that philosophical problems
arise from misunderstandings of the logic of language, and it tries to show
what this logic is. Wittgenstein's later work, principally his Philosophical
Investigations, shares this concern with logic and language, but takes a
different, less technical, approach to philosophical problems. This book helped
to inspire so-called ordinary language philosophy. This style of doing
philosophy has fallen somewhat out of favor, but Wittgenstein's work on
rule-following and private language is still considered important, and his
later philosophy is influential in a growing number of fields outside
philosophy.
1. Life
Ludwig Josef Johann Wittgenstein, born on April 26th 1889 in Vienna,
Austria, was a charismatic enigma. He has been something of a cult figure but
shunned publicity and even built an isolated hut in Norway to live in complete
seclusion. His sexuality was ambiguous but he was probably gay; how actively so
is still a matter of controversy. His life seems to have been dominated by an
obsession with moral and philosophical perfection, summed up in the subtitle of
Ray Monk's excellent biography Wittgenstein: The Duty of Genius.
His concern with moral perfection led Wittgenstein at one point to
insist on confessing to several people various sins, including that of allowing
others to underestimate the extent of his 'Jewishness'. His father Karl
Wittgenstein's parents were born Jewish but converted to Protestantism and his
mother Leopoldine (nee Kalmus) was Catholic, but her father was of Jewish
descent. Wittgenstein himself was baptized in a Catholic church and was given a
Catholic burial, although between baptism and burial he was neither a
practicing nor a believing Catholic.
The Wittgenstein family was large and wealthy. Karl Wittgenstein was one
of the most successful businessmen in the Austro-Hungarian Empire, leading the
iron and steel industry there. The Wittgensteins' home attracted people of
culture, especially musicians, including the composer Johannes Brahms, who was
a friend of the family. Music remained important to Wittgenstein throughout his
life. So did darker matters. Ludwig was the youngest of eight children, and of
his four brothers, three committed suicide.
As for his career, Wittgenstein studied mechanical engineering in Berlin
and in 1908 went to Manchester, England to do research in aeronautics,
experimenting with kites. His interest in engineering led to an interest in
mathematics which in turn got him thinking about philosophical questions about
the foundations of mathematics. He visited the mathematician and philosopher
Gottlob Frege (1848-1925), who recommended that he study with Bertrand Russell
(1872-1970) in Cambridge. At Cambridge Wittgenstein greatly impressed Russell
and G.E. Moore (1873- 1958), and began work on logic.
When his father died in 1913 Wittgenstein inherited a fortune, which he
quickly gave away. When war broke out the next year, he volunteered for the
Austrian army. He continued his philosophical work and won several medals for
bravery during the war. The result of his thinking on logic was the Tractatus
Logico-Philosophicus which was eventually published in English in 1922 with
Russell's help. This was the only book Wittgenstein published during his
lifetime. Having thus, in his opinion, solved all the problems of philosophy,
Wittgenstein became an elementary school teacher in rural Austria, where his
approach was strict and unpopular, but apparently effective. He spent 1926-28
meticulously designing and building an austere house in Vienna for his sister
Gretl.
In 1929 he returned to Cambridge to teach at Trinity College,
recognizing that in fact he had more work to do in philosophy. He became
professor of philosophy at Cambridge in 1939. During World War II he worked as
a hospital porter in London and as a research technician in Newcastle. After
the war he returned to university teaching but resigned his professorship in
1947 to concentrate on writing. Much of this he did in Ireland, preferring
isolated rural places for his work. By 1949 he had written all the material
that was published after his death as Philosophical Investigations, arguably
his most important work. He spent the last two years of his life in Vienna,
Oxford and Cambridge and kept working until he died of prostate cancer in
Cambridge in April 1951. His work from these last years has been published as
On Certainty. His last words were, "Tell them I've had a wonderful
life."
2. Tractatus
Logico-Philosophicus
Wittgenstein told Ludwig von Ficker that the point of the Tractatus was
ethical. In the preface to the book he says that its value consists in two
things: "that thoughts are expressed in it" and "that it shows
how little is achieved when these problems are solved." The problems he
refers to are the problems of philosophy defined, we may suppose, by the work
of Frege and Russell, and perhaps also Schopenhauer. At the end of the book
Wittgenstein says "My propositions serve as elucidations in the following
way: anyone who understands me eventually recognizes them as nonsensical"
[emphasis added]. What to make of the Tractatus, its author, and the
propositions it contains, then, is no easy matter.
The book certainly does not seem to be about ethics. It consists of
numbered propositions in seven sets. Proposition 1.2 belongs to the first set
and is a comment on proposition 1. Proposition 1.21 is about proposition 1.2,
and so on. The seventh set contains only one proposition, the famous "What
we cannot speak about we must pass over in silence."
Some important and representative propositions from the book are these:
1 The world is all that is the case.
4.01 “A proposition is a picture of reality.” Ludwig Wittgenstein
4.0312 ...”My fundamental idea is that the 'logical constants' are not
representatives; that there can be no representatives of the logic of facts.”
Ludwig Wittgenstein
4.121 ...!Propositions show the logical form of reality. They display
it.” Ludwig Wittgenstein
4.1212 What can be shown, cannot be said.
4.5 ...The general form of a proposition is: This is how things stand.
5.43 ...all the propositions of logic say the same thing, to wit
nothing.
5.4711 “To give the essence of a proposition means to give the essence
of all description, and thus the essence of the world.” Ludwig Wittgenstein
5.6 “The limits of my language mean the limits of my world.” Ludwig
Wittgenstein
Here and elsewhere in the Tractatus Wittgenstein seems to be saying that
the essence of the world and of life is: This is how things are. One is tempted
to add "--deal with it." That seems to fit what Cora Diamond has
called his "accept and endure" ethics, but he says that the
propositions of the Tractatus are meaningless, not profound insights, ethical
or otherwise. What are we to make of this?
Many commentators ignore or dismiss what Wittgenstein said about his
work and its aims, and instead look for regular philosophical theories in his
work. The most famous of these in the Tractatus is the "picture
theory" of meaning. According to this theory propositions are meaningful
insofar as they picture states of affairs or matters of empirical fact.
Anything normative, supernatural or (one might say) metaphysical must, it
therefore seems, be nonsense. This has been an influential reading of parts of
the Tractatus. Unfortunately, this reading leads to serious problems since by
its own lights the Tractatus' use of words like "object,"
"reality" and "world" is illegitimate. These concepts are
purely formal or a priori. A statement such as "There are objects in the
world" does not picture a state of affairs. Rather it is, as it were,
presupposed by the notion of a state of affairs. The "picture theory"
therefore denies sense to just the kind of statements of which the Tractatus is
composed, to the framework supporting the picture theory itself. In this way
the Tractatus pulls the rug out from under its own feet.
If the propositions of the Tractatus are nonsensical then they surely
cannot put forward the picture theory of meaning, or any other theory. Nonsense
is nonsense. However, this is not to say that the Tractatus itself is without
value. Wittgenstein's aim seems to have been to show up as nonsense the things
that philosophers (himself included) are tempted to say. Philosophical
theories, he suggests, are attempts to answer questions that are not really
questions at all (they are nonsense), or to solve problems that are not really
problems. He says in proposition 4.003 that:
“Most of the propositions and questions of philosophers arise from our
failure to understand the logic of our language. (They belong to the same class
as the question whether the good is more or less identical than the beautiful.)
And it is not surprising that the deepest problems are in fact not problems at
all.”
Philosophers, then, have the task of presenting the logic of our
language clearly. This will not solve important problems but it will show that
some things that we take to be important problems are really not problems at
all. The gain is not wisdom but an absence of confusion. This is not a
rejection of philosophy or logic. Wittgenstein took philosophical puzzlement
very seriously indeed, but he thought that it needed dissolving by analysis
rather than solving by the production of theories. The Tractatus presents
itself as a key for untying a series of knots both profound and highly
technical.
3. Ethics and
Religion
Wittgenstein had a lifelong interest in religion and claimed to see
every problem from a religious point of view, but never committed himself to
any formal religion. His various remarks on ethics also suggest a particular
point of view, and Wittgenstein often spoke of ethics and religion together.
This point of view or attitude can be seen in the four main themes that run
through Wittgenstein's writings on ethics and religion: goodness, value or
meaning are not to be found in the world; living the right way involves
acceptance of or agreement with the world, or life, or God's will, or fate; one
who lives this way will see the world as a miracle; there is no answer to the
problem of life--the solution is the disappearance of the problem.
Certainly Wittgenstein worried about being morally good or even perfect,
and he had great respect for sincere religious conviction, but he also said, in
his 1929 lecture on ethics, that "the tendency of all men who ever tried
to write or talk Ethics or Religion was to run against the boundaries of
language," i.e. to talk or write nonsense. This gives support to the view
that Wittgenstein believed in mystical truths that somehow cannot be expressed
meaningfully but that are of the utmost importance. It is hard to conceive,
though, what these 'truths' might be.
An alternative view is that Wittgenstein believed that there is really
nothing to say about ethics. This would explain why he wrote less and less
about ethics as his life wore on. His "accept and endure" attitude
and belief in going "the bloody hard way" are evident in all his
work, especially after the Tractatus. Wittgenstein wants his reader not to
think (too much) but to look at the "language games" (any practices
that involve language) that give rise to philosophical (personal, existential,
spiritual) problems. His approach to such problems is painstaking, thorough,
open-eyed and receptive. His ethical attitude is an integral part of his method
and shows itself as such.
But there is little to say about such an attitude short of recommending
it. In Culture and Value p.29e Wittgenstein writes:
“Rules of life are dressed up in pictures. And these pictures can only
serve to describe what we are to do, not justify it. Because they could provide
a justification only if they held good in other respects as well. I can say:
"Thank these bees for their honey as though they were kind people who have
prepared it for you"; that is intelligible and describes how I should like
you to conduct yourself. But I cannot say: "Thank them because, look, how
kind they are!"--since the next moment they may sting you.”
In a world of contingency one cannot prove that a particular attitude is
the correct one to take. If this suggests relativism, it should be remembered
that it too is just one more attitude or point of view, and one without the
rich tradition and accumulated wisdom, philosophical reasoning and personal
experience of, say, orthodox Christianity or Judaism. Indeed crude relativism,
the universal judgement that one cannot make universal judgements, is self-
contradictory. Whether Wittgenstein's views suggest a more sophisticated form
of relativism is another matter, but the spirit of relativism seems far from
Wittgenstein's conservatism and absolute intolerance of his own moral
shortcomings. Compare the tolerance that motivates relativism with Wittgenstein's
assertion to Russell that he would prefer "by far" an organization
dedicated to war and slavery to one dedicated to peace and freedom. (This
assertion, however, should not be taken literally: Wittgenstein was no
war-monger and even recommended letting oneself be massacred rather than taking
part in hand-to-hand combat. It was apparently the complacency, and perhaps the
self-righteousness, of Russell's liberal cause that Wittgenstein objected to.)
With regard to religion, Wittgenstein is often considered a kind of
Anti-Realist (see below for more on this). He opposed interpretations of
religion that emphasize doctrine or philosophical arguments intended to prove
God's existence, but was greatly drawn to religious rituals and symbols, and
considered becoming a priest. He likened the ritual of religion to a great
gesture, as when one kisses a photograph. This is not based on the false belief
that the person in the photograph will feel the kiss or return it, nor is it
based on any other belief. Neither is the kiss just a substitute for a
particular phrase, like "I love you." Like the kiss, religious
activity does express an attitude, but it is not just the expression of an
attitude in the sense that several other forms of expression might do just as
well. There might be no substitute that would do. The same might be said of the
whole language-game (or games) of religion, but this is a controversial point.
If religious utterances, such as "God exists," are treated as
gestures of a certain kind then this seems not to be treating them as literal
statements. Many religious believers, including Wittgensteinian ones, would
object strongly to this. There is room, though, for a good deal of
sophisticated disagreement about what it means to take a statement literally. For
instance, Charles Taylor's view, roughly, is that the real is whatever will not
go away. If we cannot reduce talk about God to anything else, or replace it, or
prove it false, then perhaps God is as real as anything else.
4. Conception of
Philosophy
Wittgenstein's view of what philosophy is, or should be, changed little
over his life. In the Tractatus he says at 4.111 that "philosophy is not
one of the natural sciences," and at 4.112 "Philosophy aims at the
logical clarification of thoughts." Philosophy is not descriptive but
elucidatory. Its aim is to clear up muddle and confusion. It follows that
philosophers should not concern themselves so much with what is actual, keeping
up with the latest popularizations of science, say, which Wittgenstein despised.
The philosopher's proper concern is with what is possible, or rather with what
is conceivable. This depends on our concepts and the ways they fit together as
seen in language. What is conceivable and what is not, what makes sense and
what does not, depends on the rules of language, of grammar.
In Philosophical Investigations Sect. 90 Wittgenstein says:
“Our investigation is a grammatical one. Such an investigation sheds
light on our problem by clearing misunderstandings away. Misunderstandings
concerning the use of words, caused, among other things, by certain analogies
between the forms of expression in different regions of language.”
The similarities between the sentences "I'll keep it in mind"
and "I'll keep it in this box," for instance, (along with many
others) can lead one to think of the mind as a thing something like a box with
contents of its own. The nature of this box and its mental contents can then
seem very mysterious. Wittgenstein suggests that one way, at least, to deal
with such mysteries is to recall the different things one says about minds,
memories, thoughts and so on, in a variety of contexts.
What one says, or what people in general say, can change. Ways of life
and uses of language change, so meanings change, but not utterly and
instantaneously. Things shift and evolve, but rarely if ever so drastically
that we lose all grip on meaning. So there is no timeless essence of at least
some and perhaps all concepts, but we still understand one another well enough
most of the time.
When nonsense is spoken or written, or when something just seems fishy,
we can sniff it out. The road out of confusion can be a long and difficult one,
hence the need for constant attention to detail and particular examples rather
than generalizations, which tend to be vague and therefore potentially
misleading. The slower the route, the surer the safety at the end of it. That
is why Wittgenstein said that in philosophy the winner is the one who finishes
last. But we cannot escape language or the confusions to which it gives rise,
except by dying. In the meantime, Wittgenstein offers four main methods to
avoid philosophical confusion, as described by Norman Malcolm: describing
circumstances in which a seemingly problematic expression might actually be
used in everyday life, comparing our use of words with imaginary language
games, imagining fictitious natural history, and explaining psychologically the
temptation to use a certain expression inappropriately.
The complex, intertwined relationship between a language and the form of
life that goes with it means that problems arising from language cannot just be
set aside--they infect our lives, making us live in confusion. We might find
our way back to the right path, but there is no guarantee that we will never again
stray. In this sense there can be no progress in philosophy.
In 1931 Wittgenstein described his task thus:
“Language sets everyone the same traps; it is an immense network of
easily accessible wrong turnings. And so we watch one man after another walking
down the same paths and we know in advance where he will branch off, where walk
straight on without noticing the side turning, etc. etc. What I have to do then
is erect signposts at all the junctions where there are wrong turnings so as to
help people past the danger points.”
But such signposts are all that philosophy can offer and there is no
certainty that they will be noticed or followed correctly. And we should
remember that a signpost belongs in the context of a particular problem area.
It might be no help at all elsewhere, and should not be treated as dogma. So
philosophy offers no truths, no theories, nothing exciting, but mainly
reminders of what we all know. This is not a glamorous role, but it is
difficult and important. It requires an almost infinite capacity for taking
pains (which is one definition of genius) and could have enormous implications
for anyone who is drawn to philosophical contemplation or who is misled by bad
philosophical theories. This applies not only to professional philosophers but
to any people who stray into philosophical confusion, perhaps not even
realizing that their problems are philosophical and not, say, scientific.
5. Meaning
Sect. 43 of Wittgenstein's Philosophical Investigations says that:
"For a large class of cases--though not for all--in which we employ the
word "meaning" it can be defined thus: the meaning of a word is its
use in the language."
It is quite clear that here Wittgenstein is not offering the general
theory that "meaning is use," as he is sometimes interpreted as
doing. The main rival views that Wittgenstein warns against are that the
meaning of a word is some object that it names--in which case the meaning of a
word could be destroyed, stolen or locked away, which is nonsense--and that the
meaning of a word is some psychological feeling--in which case each user of a
word could mean something different by it, having a different feeling, and
communication would be difficult if not impossible.
Knowing the meaning of a word can involve knowing many things: to what
objects the word refers (if any), whether it is slang or not, what part of
speech it is, whether it carries overtones, and if so what kind they are, and
so on. To know all this, or to know enough to get by, is to know the use. And
generally knowing the use means knowing the meaning. Philosophical questions
about consciousness, for example, then, should be responded to by looking at
the various uses we make of the word "consciousness." Scientific
investigations into the brain are not directly relevant to this inquiry
(although they might be indirectly relevant if scientific discoveries led us to
change our use of such words). The meaning of any word is a matter of what we
do with our language, not something hidden inside anyone's mind or brain. This
is not an attack on neuroscience. It is merely distinguishing philosophy (which
is properly concerned with linguistic or conceptual analysis) from science
(which is concerned with discovering facts).
One exception to the meaning-is-use rule of thumb is given in
Philosophical Investigations Sect.561, where Wittgenstein says that "the
word "is" is used with two different meanings (as the copula and as
the sign of equality)" but that its meaning is not its use. That is to say,
"is" has not one complex use (including both "Water is
clear" and "Water is H2O") and therefore one complex meaning,
but two quite distinct uses and meanings. It is an accident that the same word
has these two uses. It is not an accident that we use the word "car"
to refer to both Fords and Hondas. But what is accidental and what is essential
to a concept depends on us, on how we use it.
This is not completely arbitrary, however. Depending on one's
environment, one's physical needs and desires, one's emotions, one's sensory capacities,
and so on, different concepts will be more natural or useful to one. This is
why "forms of life" are so important to Wittgenstein. What matters to
you depends on how you live (and vice versa), and this shapes your experience.
So if a lion could speak, Wittgenstein says, we would not be able to understand
it. We might realize that "roar" meant zebra, or that "roar,
roar" meant lame zebra, but we would not understand lion ethics, politics,
aesthetic taste, religion, humor and such like, if lions have these things. We
could not honestly say "I know what you mean" to a lion.
Understanding another involves empathy, which requires the kind of similarity
that we just do not have with lions, and that many people do not have with
other human beings.
When a person says something what he or she means depends not only on
what is said but also on the context in which it is said. Importance, point,
meaning are given by the surroundings. Words, gestures, expressions come alive,
as it were, only within a language game, a culture, a form of life. If a
picture, say, means something then it means so to somebody. Its meaning is not
an objective property of the picture in the way that its size and shape are.
The same goes of any mental picture. Hence Wittgenstein's remark that "If
God had looked into our minds he would not have been able to see there whom we
were speaking of." Any internal image would need interpretation. If I
interpret my thought as one of Hitler and God sees it as Charlie Chaplin, who
is right? Which of the two famous contemporaries of Wittgenstein's I mean shows
itself in the way I behave, the things I do and say. It is in this that the
use, the meaning, of my thought or mental picture lies. "The arrow points
only in the application that a living being makes of it."
6. Rules and
Private Language
Without sharing certain attitudes towards the things around us, without
sharing a sense of relevance and responding in similar ways, communication
would be impossible. It is important, for instance, that nearly all of us agree
nearly all the time on what colors things are. Such agreement is part of our
concept of color, Wittgenstein suggests. Regularity of the use of such concepts
and agreement in their application is part of language, not a logically necessary
precondition of it. We cannot separate the life in which there is such
agreement from our concept of color. Imagine a different form or way of life
and you imagine a different language with different concepts, different rules
and a different logic.
This raises the question of the relation between language and forms or
ways of life. For instance, could just one person have a language of his or her
own? To imagine an individual solitary from birth is scarcely to imagine a form
of life at all, but more like just imagining a life- form. Moreover, language
involves rules establishing certain linguistic practices. Rules of grammar
express the fact that it is our practice to say this (e.g. "half past
twelve") and not that (e.g. "half to one"). Agreement is essential
to such practices. Could a solitary individual, then, engage in any practice,
including linguistic ones? With whom could he or she agree? This is a
controversial issue in the interpretation of Wittgenstein. Gordon Baker and
P.M.S. Hacker hold that such a solitary man could speak his own language,
follow his own rules, and so on, agreeing, over time, with himself in his
judgements and behavior. Orthodoxy is against this interpretation, however.
Norman Malcolm has written that "If you conceive of an individual
who has been in solitude his whole life long, then you have cut away the
background of instruction, correction, acceptance--in short, the circumstances
in which a rule is given, enforced, and followed." Mere regularity of
behavior does not constitute following rules, whether they be rules of grammar
or any other kind. A car that never starts in cold weather does not follow the
rule "Don't start when it's cold," nor does a songbird follow a rule
in singing the same song every day. Whether a solitary-from-birth individual
would ever do anything that we would properly call following a rule is at least
highly doubtful. How could he or she give himself or herself a rule to follow
without language? And how could he or she get a language? Inventing one would
involve inventing meaning, as Rush Rhees has argued, and this sounds
incoherent. (The most famous debate about this was between Rhees and A.J. Ayer.
Unfortunately for Wittgenstein, Ayer is generally considered to have won.)
Alternatively, perhaps the Crusoe-like figure just does behave, sound, etc.
just like a native speaker of, say, English. But this is to imagine either a
freakish automaton, not a human being, or else a miracle. In the case of a
miracle, Wittgenstein says, it is significant that we imagine not just the
pseudo- Crusoe but also God. In the case of the automatic speaker, we might
adopt what Daniel Dennett calls an "intentional stance" towards him,
calling what he does "speaking English," but he is obviously not
doing what the rest of us English-speakers--who learned the language, rather
than being born speaking it, and who influence and are influenced by others in
our use of the language--do.
The debate about solitary individuals is sometimes referred to as the
debate about "private language." Wittgenstein uses this expression in
another context, however, to name a language that refers to private sensations.
Such a private language by definition cannot be understood by anyone other than
its user (who alone knows the sensations to which it refers). Wittgenstein
invites us to imagine a man who decides to write 'S' in his diary whenever he
has a certain sensation. This sensation has no natural expression, and 'S'
cannot be defined in words. The only judge of whether 'S' is used correctly is
the inventor of 'S'. The only criterion of correctness is whether a sensation
feels the same to him or her. There are no criteria for its being the same
other than its seeming the same. So he writes 'S' when he feels like it. He
might as well be doodling. The so-called 'private language' is no language at
all. The point of this is not to show that a private language is impossible but
to show that certain things one might want to say about language are ultimately
incoherent. If we really try to picture a world of private objects (sensations)
and inner acts of meaning and so on, we see that what we picture is either
regular public language or incomprehensible behavior (the man might as well
quack as say or write 'S').
This does not, as has been alleged, make Wittgenstein a behaviorist. He
does not deny the existence of sensations or experiences. Pains, tickles,
itches, etc. are all part of human life, of course. At Philosophical
Investigations Sect. 293 Wittgenstein says that "if we construe the grammar
of the expression of sensation on the model of 'object and designation' the
object drops out of consideration as irrelevant." This suggests not that
pains and so on are irrelevant but that we should not construe the grammar of
the expression of sensation on the model of 'object and designation'. If we
want to understand a concept like pain we should not think of a pain as a
private object referred to somehow by the public word "pain." A pain
is not "a something," just as love, democracy and strength are not things,
but it is no more "a nothing" than they are either (see Philosophical
Investigations Sect. 304). Saying this is hardly satisfactory, but there is no
simple answer to the question "What is pain?" Wittgenstein offers not
an answer but a kind of philosophical 'therapy' intended to clear away what can
seem so obscure. To judge the value of this therapy, the reader will just have
to read Wittgenstein's work for herself.
The best known work on Wittgenstein's writings on this whole topic is
Saul A. Kripke's Wittgenstein on Rules and Private Language. Kripke is struck
by the idea that anything might count as continuing a series or following a
rule in the same way. It all depends on how the rule or series is interpreted.
And any rule for interpretation will itself be subject to a variety of
interpretations, and so on. What counts as following a rule correctly, then, is
not determined somehow by the rule itself but by what the relevant linguistic
community accepts as following the rule. So whether two plus two equals four
depends not on some abstract, extra-human rule of addition, but on what we, and
especially the people we appoint as experts, accept. Truth conditions are
replaced by assertability conditions. To put it crudely, what counts is not
what is true or right (in some sense independent of the community of language
users), but what you can get away with or get others to accept.
Kripke's theory is clear and ingenious, and owes a lot to Wittgenstein,
but is doubtful as an interpretation of Wittgenstein. Kripke himself presents
the argument not as Wittgenstein's, nor as his own, but as "Wittgenstein's
argument as it struck Kripke" (Kripke p.5). That the argument is not
Wittgenstein's is suggested by the fact that it is a theory, and Wittgenstein rejected
philosophical theories, and by the fact that the argument relies heavily on the
first sentence of Philosophical Investigations Sect. 201: "This was our
paradox: no course of action could be determined by a rule, because every
course of action can be made out to accord with the rule." For Kripke's
theory as a reading of Wittgenstein, it is not good that the very next
paragraph begins, "It can be seen that there is a misunderstanding
here..." Still, it is no easy matter to see just where Wittgenstein does
diverge from the hybrid person often referred to as 'Kripkenstein'. The key
perhaps lies later in the same paragraph, where Wittgenstein writes that
"there is a way of grasping a rule which is not an interpretation".
Many scholars, notably Baker and Hacker, have gone to great lengths to explain
why Kripke is mistaken. Since Kripke is so much easier to understand, one of
the best ways into Wittgenstein's philosophy is to study Kripke and his
Wittgensteinian critics. At the very least, Kripke introduces his readers well
to issues that were of great concern to Wittgenstein and shows their
importance.
7. Realism and
Anti-Realism
Wittgenstein's place in the debate about philosophical Realism and
Anti-Realism is an interesting one. His emphasis on language and human
behavior, practices, etc. makes him a prime candidate for Anti-Realism in many
people's eyes. He has even been accused of linguistic idealism, the idea that
language is the ultimate reality. The laws of physics, say, would by this
theory just be laws of language, the rules of the language game of physics.
Anti-Realist scepticism of this kind has proved quite popular in the philosophy
of science and in theology, as well as more generally in metaphysics and
ethics.
On the other hand, there is a school of Wittgensteinian Realism, which
is less well known. Wittgenstein's views on religion, for instance, are often
compared with those of Simone Weil, who was a Platonist of sorts. Sabina
Lovibond argues for a kind of Wittgensteinian Realism in ethics in her Realism
and Imagination in Ethics and the influence of Wittgenstein is clear in Raimond
Gaita's Good and Evil: An Absolute Conception. However, one should not go too
far with the idea of Wittgensteinian Realism. Lovibond, for instance, equates
objectivity with intersubjectivity (universal agreement), so her Realism is of
a controversial kind.
Both Realism and Anti-Realism, though, are theories, or schools of
theories, and Wittgenstein explicitly rejects the advocacy of theories in
philosophy. This does not prove that he practiced what he preached, but it
should give us pause. It is also worth noting that supporters of Wittgenstein
often claim that he was neither a Realist nor an Anti-Realist, at least with
regard to metaphysics. There is something straightforwardly unWittgensteinian
about the Realist's belief that language/thought can be compared with reality
and found to 'agree' with it. The Anti-Realist says that we could not get
outside our thought or language (or form of life or language games) to compare
the two. But Wittgenstein was concerned not with what we can or cannot do, but
with what makes sense. If metaphysical Realism is incoherent then so is its
opposite. The nonsensical utterance "laubgefraub" is not to be
contradicted by saying, "No, it is not the case that laubgefraub," or
"Laubgefraub is a logical impossibility." If Realism is truly
incoherent, as Wittgenstein would say, then so is Anti-Realism.
8. Certainty
Wittgenstein's last writings were on the subject of certainty. He wrote
in response to G.E. Moore's attack on scepticism about the external world.
Moore had held up one hand, said "Here is one hand," then held up his
other hand and said "and here is another." His point was that things
outside the mind really do exist, we know they do, and that no grounds for
scepticism could be strong enough to undermine this commonsense knowledge.
Wittgenstein did not defend scepticism, but questioned Moore's claim to
know that he had two hands. Such 'knowledge' is not something that one is ever
taught, or finds out, or proves. It is more like a background against which we
come to know other things. Wittgenstein compares this background to the bed of
a river. This river bed provides the support, the context, in which claims to
know various things have meaning. The bed itself is not something we can know
or doubt. In normal circumstances no sane person doubts how many hands he or
she has. But unusual circumstances can occur and what was part of the river bed
can shift and become part of the river. I might, for instance, wake up dazed
after a terrible accident and wonder whether my hands, which I cannot feel, are
still there or not. This is quite different, though, from Descartes's pretended
doubt as to whether he has a body at all. Such radical doubt is really not
doubt at all, from Wittgenstein's point of view. And so it cannot be dispelled
by a proof that the body exists, as Moore tried to do.
9. Continuity
Wittgenstein is generally considered to have changed his thinking
considerably over his philosophical career. His early work culminated in the
Tractatus Logico-Philosophicus with its picture theory of language and mysticism,
according to this view. Then there came a transitional middle period when he
first returned to philosophical work after realizing that he had not solved all
the problems of philosophy. This period led to his mature, later period which
gave us the Philosophical Investigations and On Certainty.
There certainly are marked changes in Wittgenstein's work, but the
differences between his early and late work can be exaggerated. Two central
discontinuities in his work are these: whereas the Tractatus is concerned with
the general form of the proposition, the general nature of metaphysics, and so
on, in his later work Wittgenstein is very critical of "the craving for
generality"; and, in the Tractatus Wittgenstein speaks of the central
problems of philosophy, whereas the later work treats no problems as central.
Another obvious difference is in Wittgenstein's style. The Tractatus is a
carefully constructed set of short propositions. The Investigations, though
also consisting of numbered sections, is longer, less clearly organized and
more rambling, at least in appearance. This reflects Wittgenstein's rejection
of the idea that there are just a few central problems in philosophy, and his
insistence on paying attention to particular cases, going over the rough ground.
On the other hand, the Tractatus itself says that its propositions are
nonsense and thus, in a sense (not easy to understand), rejects itself. The
fact that the later work also criticizes the Tractatus is not, therefore, proof
of discontinuity in Wittgenstein's work. The main change may have been one of
method and style. Problems are investigated one at a time, although many
overlap. There is not a full-frontal assault on the problem or problems of philosophy.
Otherwise, the Tractatus and the Philosophical Investigations attack much the
same problems; they just do so in different ways.
10. Wittgenstein
in History
Wittgenstein's place in the history of philosophy is a peculiar one. His
philosophical education was unconventional (going from engineering to working
first-hand with one of the greatest philosophers of his day in Bertrand
Russell) and he seems never to have felt the need to go back and make a
thorough study of the history of philosophy. He was interested in Plato,
admired Leibniz, but was most influenced by the work of Schopenhauer, Russell
and Frege.
From Schopenhauer (perhaps) Wittgenstein got his interest in solipsism
and in the ethical nature of the relation between the will and the world.
Schopenhauer's saying that "The world is my idea," (from The World as
Will and Idea) is echoed in such remarks as "The world is my world"
(from Tractatus 5.62). What Wittgenstein means here, where he also says that
what the solipsist means is quite correct, but that it cannot be said, is
obscure and controversial. Some have taken him to mean that solipsism is true
but for some reason cannot be expressed. H.O. Mounce, in his valuable
Wittgenstein's Tractatus: An Introduction, says that this interpretation is
surely wrong. Mounce's view is that Wittgenstein holds solipsism itself to be a
confusion, but one that sometimes arises when one tries to express the fact
that "I have a point of view on the world which is without
neighbours." (Mounce p.91) Wittgenstein was not a solipsist but he
remained interested in solipsism and related problems of scepticism throughout
his life.
Frege was a mathematician as well as a logician. He was interested in
questions of truth and falsehood, sense and reference (a distinction he made
famous) and in the relation between objects and concepts, propositions and
thoughts. But his interest was in logic and mathematics exclusively, not in
psychology or ethics. His great contribution to logic was to introduce various
mathematical elements into formal logic, including quantification, functions,
arguments (in the mathematical sense of something substituted for a variable in
a function) and the value of a function. In logic this value, according to
Frege, is always either the True or the False, hence the notion of truth-value.
Both Frege and Russell wanted to show that mathematics is an extension of
logic. Undoubtedly both men influenced Wittgenstein enormously, especially
since he worked first-hand with Russell. Some measure of their importance to
him can be seen in the preface to the Tractatus, where Wittgenstein says that
he is "indebted to Frege's great works and to the writings of my friend Mr
Bertrand Russell for much of the stimulation of my thoughts." For some
insight into whether Frege or Russell had the greater influence one can
consider whether one would rather be recognized for his or her great works or
for simply being a friend.
In turn Wittgenstein influenced twentieth century philosophy enormously.
The Vienna Circle logical positivists were greatly impressed by what they found
in the Tractatus, especially the idea that logic and mathematics are analytic,
the verifiability principle and the idea that philosophy is an activity aimed
at clarification, not the discovery of facts. Wittgenstein, though, said that
it was what is not in the Tractatus that matters most.
The other group of philosophers most obviously indebted to Wittgenstein
is the ordinary language or Oxford school of thought. These thinkers were more
interested in Wittgenstein's later work and its attention to grammar.
Wittgenstein is thus a doubly key figure in the development and history
of analytic philosophy, but he has become rather unfashionable because of his
anti-theoretical, anti-scientism stance, because of the difficulty of his work,
and perhaps also because he has been little understood. Similarities between
Wittgenstein's work and that of Derrida are now generating interest among
continental philosophers, and Wittgenstein may yet prove to be a driving force
behind the emerging post-analytic school of philosophy.
