Relation to Wittgenstein's body of work
In its preface, Wittgenstein says that ''Philosophical Investigations'' can be understood "only by contrast with and against the background of my old way of thinking". That "old way of thinking" is to be found in the only book Wittgenstein published in his lifetime, the ''

The ''Tractatus Logico-Philosophicus'' (widely abbreviated and cited as TLP) is a book-length philosophical work by the Austrian philosopher Ludwig Wittgenstein which deals with the relationship between language and reality and aims to define th ...

The ''
Blue and Brown Books'', a set of notes dictated to his class at Cambridge in 1933–1934, contains the seeds of Wittgenstein's later thoughts on language and is widely read as a turning-point in his philosophy of language.

Themes
Language-games
Wittgenstein develops this discussion of games into the key notion of a ''
language-game
A language-game (german: Sprachspiel) is a philosophical concept developed by Ludwig Wittgenstein, referring to simple examples of language use and the actions into which the language is woven. Wittgenstein argued that a word or even a sentence h ...
''. For Wittgenstein, his use of the term language-game "is meant to bring into prominence the fact that the speaking of language is part of an activity, or of a life-form."
A central feature of language-games is that language is used in context and that language cannot be understood outside of its context. Wittgenstein lists the following as examples of language-games: “Giving orders, and obeying them”; “
scribing the appearance of an object, or giving its measurements”; “
nstructing an object from a description (a drawing)”; “
porting an event”; “
eculating about an event."
The famous example is the meaning of the word "game". We speak of various kinds of games: board games, betting games, sports, "war games". These are all different uses of the word "games". Wittgenstein also gives the example of "Water!", which can be used as an exclamation, an order, a request, or as an answer to a question. The meaning of the word depends on the language-game within which it is being used. Another way Wittgenstein puts the point is that the word "water" has no meaning apart from its use within a language-game. One might use the word as an order to have someone else bring you a glass of water. But it can also be used to warn someone that the water has been poisoned. One might even use the word as code by members of a secret society.
Wittgenstein does not limit the application of his concept of language games to word-meaning. He also applies it to sentence-meaning. For example, the sentence "Moses did not exist" (§79) can mean various things. Wittgenstein argues that, independent of use, the sentence does not yet 'say' anything. It is 'meaningless' in the sense of not being significant for a particular purpose. It only acquires significance if we fix it within some context of use. Thus, it fails to say anything because the sentence as such does not yet determine some particular use. The sentence is only meaningful when it is used to say something. For instance, it can be used so as to say that no person or historical figure fits the set of descriptions attributed to the person that goes by the name of "Moses". But it can also mean that the leader of the Israelites was not called Moses. Or that there cannot have been anyone who accomplished all that the Bible relates of Moses, etc. What the sentence means thus depends on its context of use.
Meaning as use
The ''Investigations'' deals largely with the difficulties of language and
meaning. Wittgenstein viewed the tools of language as being fundamentally simple and he believed that philosophers had obscured this simplicity by misusing language and by asking meaningless questions. He attempted in the ''Investigations'' to make things clear: "''Der Fliege den Ausweg aus dem Fliegenglas zeigen''"—to show the fly the way out of the
fly bottle.
Wittgenstein claims that the meaning of a word is based on how the word is understood within the language-game. A common summary of his argument is that meaning is use. According to the use theory of meaning, the words are not defined by reference to the objects they designate, nor by the mental representations one might associate with them, but by how they are used. For example, this means there is no need to postulate that there is something called ''good'' that exists independently of any good deed. Wittgenstein's use theory of meaning contrasts with

. This argument has been labeled by some authors as "anthropological holism".
Section 43 in Wittgenstein's ''Philosophical Investigations'' reads: "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."
Wittgenstein begins ''Philosophical Investigations'' with a quote from
Augustine's ''Confessions'', which represents the view that language serves to point out objects in the world, and the view that he will be criticizing.
The individual words in language name objects—sentences are combinations of such names. In this picture of language we find the roots of the following idea: Every word has a meaning. This meaning is correlated with the word. It is the object for which the word stands.
Wittgenstein rejects a variety of ways of thinking about what the meaning of a word is, or how meanings can be identified. He shows how, in each case, the ''meaning'' of the word presupposes our ability to use it. He first asks the reader to perform a thought experiment: to come up with a
definition of the word "game". While this may at first seem a simple task, he then goes on to lead us through the problems with each of the possible definitions of the word "game". Any definition that focuses on amusement leaves us unsatisfied since the feelings experienced by a world class

. Any definition that focuses on competition will fail to explain the game of catch, or the game of
solitaire. And a definition of the word "game" that focuses on rules will fall on similar difficulties.
The essential point of this exercise is often missed. Wittgenstein's point is not that it is impossible to define "game", but that ''even if we don't have a definition, we can still use the word successfully''. Everybody understands what we mean when we talk about playing a game, and we can even clearly identify and correct inaccurate uses of the word, all without reference to any definition that consists of

s for the application of the concept of a game. The German word for "game", "
Spiele/Spiel", has a different sense than in English; the meaning of "Spiele" also extends to the concept of "play" and "playing." This German sense of the word may help readers better understand Wittgenstein's context in the remarks regarding games.
Wittgenstein argues that definitions emerge from what he termed "
forms of life", roughly the culture and society in which they are used. Wittgenstein stresses the social aspects of cognition; to see how language works for most cases, we have to see how it functions in a specific social situation. It is this emphasis on becoming attentive to the social backdrop against which language is rendered intelligible that explains Wittgenstein's elliptical comment that "If a lion could talk, we could not understand him." However, in proposing the thought experiment involving the fictional character,

activities: teaching, explanations, techniques and criteria of correctness. In short, it is essential that a language is shareable, but this does not imply that for a language to function that it is in fact already shared.
Wittgenstein rejects the idea that
ostensive definitions can provide us with the meaning of a word. For Wittgenstein, the thing that the word stands for does ''not'' give the meaning of the word. Wittgenstein argues for this making a series of moves to show that to understand an ostensive definition presupposes an understanding of the way the word being defined is used. So, for instance, there is no difference between pointing to a piece of paper, to its colour, or to its shape; but understanding the difference is crucial to using the paper in an ostensive definition of a shape or of a colour.

How do we recognize that two people we know are related to one another?

. It is perhaps important to note that this is not always a conscious process—generally we don't catalog various similarities until we reach a certain threshold, we just intuitively ''see'' the resemblances. Wittgenstein suggests that the same is true of language. We are all familiar (i.e. socially) with enough things which ''are games'' and enough things which ''are not games'' that we can categorize new activities as either games or not.
This brings us back to Wittgenstein's reliance on indirect communication, and his reliance on thought-experiments. Some philosophical confusions come about because we aren't able to ''see'' family resemblances. We've made a mistake in understanding the vague and intuitive rules that language uses, and have thereby tied ourselves up in philosophical knots. He suggests that an attempt to untangle these knots requires more than simple deductive arguments pointing out the problems with some particular position. Instead, Wittgenstein's larger goal is to try to divert us from our philosophical problems long enough to become aware of our intuitive ability to ''see'' the family resemblances.
Rules and rule-following
Wittgenstein's discussion of rules and rule-following ranges from § 138 through § 242. Wittgenstein begins his discussion of rules with the example of one person giving orders to another "to write down a series of signs according to a certain formation rule." The series of signs consists of the natural numbers. Wittgenstein draws a distinction between following orders by copying the numbers following instruction and understanding the construction of the series of numbers. One general characteristic of games that Wittgenstein considers in detail is the way in which they consist in following rules. Rules constitute a family, rather than a class that can be explicitly defined. As a consequence, it is not possible to provide a definitive account of what it is to follow a rule. Indeed, he argues that ''any'' course of action can be made out to accord with some particular rule, and that therefore a rule cannot be used to explain an action. Rather, that one is following a rule or not is to be decided by looking to see if the actions conform to the expectations in the particular ''form of life'' in which one is involved. Following a rule is a social activity.

provides
an influential discussion of Wittgenstein's remarks on rules. For Kripke, Wittgenstein's discussion of rules "may be regarded as a new form of philosophical scepticism." He starts his discussion of Wittgenstein by quoting what he describes as Wittgenstein's sceptical paradox: "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. The answer was: if everything can be made out to accord with the rule, then it can also be made out to conflict with it. And so there would be neither accord nor conflict here." Kripke argues that the implications of Wittgenstein's discussion of rules is that no person can mean something by the language that they use or correctly follow (or fail to follow) a rule.
Private language
Wittgenstein also ponders the possibility of a language that talks about those things that are known only to the user, whose content is inherently private. The usual example is that of a language in which one names one's sensations and other subjective experiences, such that the meaning of the term is decided by the individual alone. For example, the individual names a particular sensation, on some occasion, 'S', and intends to use that word to refer to that sensation. Such a language Wittgenstein calls a ''private language''.
Wittgenstein presents several perspectives on the topic. One point he makes is that it is incoherent to talk of ''knowing'' that one is in some particular mental state. Whereas others can learn of my pain, for example, I simply ''have'' my own pain; it follows that one does not ''know'' of one's own pain, one simply ''has'' a pain. For Wittgenstein, this is a grammatical point, part of the way in which the language-game involving the word "pain" is played.
Although Wittgenstein certainly argues that the notion of private language is incoherent, because of the way in which the text is presented the exact nature of the argument is disputed. First, he argues that a private language is not really a language at all. This point is intimately connected with a variety of other themes in his later works, especially his investigations of "meaning". For Wittgenstein, there is no single, coherent "sample" or "object" that we can call "meaning". Rather, the supposition that there are such things is the source of many philosophical confusions. Meaning is a complicated phenomenon that is woven into the fabric of our lives. A good first approximation of Wittgenstein's point is that meaning is a ''social'' event; meaning happens ''between'' language users. As a consequence, it makes no sense to talk about a private language, with words that ''mean'' something in the absence of other users of the language.
Wittgenstein also argues that one couldn't possibly ''use'' the words of a private language. He invites the reader to consider a case in which someone decides that each time she has a particular sensation she will place a sign S in a diary. Wittgenstein points out that in such a case one could have no criteria for the correctness of one's use of S. Again, several examples are considered. One is that perhaps using S involves mentally consulting a table of sensations, to check that one has associated S correctly; but in this case, how could the mental table be checked for its correctness? It is "
if someone were to buy several copies of the morning paper to assure himself that what it said was true", as Wittgenstein puts it. One common interpretation of the argument is that while one may have direct or privileged access to one's ''current'' mental states, there is no such infallible access to identifying previous mental states that one had in the past. That is, the only way to check to see if one has applied the symbol S correctly to a certain mental state is to introspect and determine whether the current sensation is identical to the sensation previously associated with S. And while identifying one's current mental state of remembering may be infallible, whether one remembered correctly is not infallible. Thus, for a language to be used at all it must have some public criterion of identity.
Often, what is widely regarded as a deep philosophical problem will vanish, argues Wittgenstein, and eventually be seen as a confusion about the significance of the words that philosophers use to frame such problems and questions. It is only in this way that it is interesting to talk about something like a "private language" — i.e., it is helpful to see how the "problem" results from a misunderstanding.
To sum up: Wittgenstein asserts that, if something is a language, it ''cannot'' be (logically) private; and if something ''is'' private, it is not (and cannot be) a language.
Wittgenstein's beetle
Another point that Wittgenstein makes against the possibility of a private language involves the beetle-in-a-box thought experiment.
[§293] He asks the reader to imagine that each person has a box, inside which is something that everyone intends to refer to with the word "beetle". Further, suppose that no one can look inside another's box, and each claims to know what a "beetle" is only by examining their own box. Wittgenstein suggests that, in such a situation, the word "beetle" could not be the name of a thing, because supposing that each person has something completely different in their boxes (or nothing at all) does not change the meaning of the word; the beetle as a private object "drops out of consideration as irrelevant".
Thus, Wittgenstein argues, if we can talk about something, then it is not ''private'', in the sense considered. And, contrapositively, if we consider something to be indeed private, it follows that we ''cannot talk about it''.
Mind
Wittgenstein's investigations of language lead to several issues concerning the mind. His key target of criticism is any form of extreme mentalism that posits mental states that are entirely unconnected to the subject's environment. For Wittgenstein, thought is inevitably tied to language, which is inherently social. Part of Wittgenstein's credo is captured in the following proclamation: "An 'inner process' stands in need of outward criteria." This follows primarily from his conclusions about private languages: similarly, a private mental state (a sensation of pain, for example) cannot be adequately discussed without public criteria for identifying it.
According to Wittgenstein, those who insist that consciousness (or any other apparently subjective mental state) is conceptually unconnected to the external world are mistaken. Wittgenstein explicitly criticizes so-called
conceivability arguments: "Could one imagine a stone's having consciousness? And if anyone can do so—why should that not merely prove that such image-mongery is of no interest to us?" He considers and rejects the following reply as well:
"But if I suppose that someone is in pain, then I am simply supposing that he has just the same as I have so often had." — That gets us no further. It is as if I were to say: "You surely know what 'It is 5 o'clock here' means; so you also know what 'It's 5 o'clock on the sun' means. It means simply that it is just the same there as it is here when it is 5 o'clock." — The explanation by means of ''identity'' does not work here.
Thus, according to Wittgenstein, mental states are intimately connected to a subject's environment, especially their linguistic environment, and conceivability or imaginability. Arguments that claim otherwise are misguided.
''Seeing that'' vs. ''seeing as''
In addition to ambiguous sentences, Wittgenstein discussed figures that can be seen and understood in two different ways. Often one can see something in a straightforward way — seeing ''that'' it is a rabbit, perhaps. But, at other times, one notices a particular aspect — seeing it ''as'' something.
An example Wittgenstein uses is the "
duckrabbit", an
ambiguous image

that can be ''seen as'' either a duck or a rabbit. When one looks at the duck-rabbit and sees a rabbit, one is not ''interpreting'' the picture as a rabbit, but rather ''reporting'' what one sees. One just sees the picture as a rabbit. But what occurs when one sees it first as a duck, then as a rabbit? As the gnomic remarks in the ''Investigations'' indicate, Wittgenstein isn't sure. However, he is sure that it could not be the case that the external world stays the same while an 'internal' cognitive change takes place.

made the following comment on the ''Philosophical Investigations'' in his book ''
My Philosophical Development'':
I have not found in Wittgenstein's Philosophical Investigations anything that seemed to me interesting and I do not understand why a whole school finds important wisdom in its pages. Psychologically this is surprising. The earlier Wittgenstein, whom I knew intimately, was a man addicted to passionately intense thinking, profoundly aware of difficult problems of which I, like him, felt the importance, and possessed (or at least so I thought) of true philosophical genius. The later Wittgenstein, on the contrary, seems to have grown tired of serious thinking and to have invented a doctrine which would make such an activity unnecessary. I do not for one moment believe that the doctrine which has these lazy consequences is true. I realize, however, that I have an overpoweringly strong bias against it, for, if it is true, philosophy is, at best, a slight help to lexicographers, and at worst, an idle tea-table amusement.
