Suppose [s|I] said “there is something there”; & on being asked, “[w|W]hat do you mean?”, I painted a picture of what I see. Would this justify saying saying that statement? – Wouldn't this picture have to be understood as ‘in a system’? And mustn't I understand Ms-151,2 2. it as an expression within a system?

If one sais to the solipsist John Smith “so you say that of all people only John [s|S]mith really sees”, he doesnt really recognize this to be his view. He didn't really mean that if you regard him as one man amongst other men person out of many people he had any special privilege. – He would be inclined to say: “Not John Smith has any particular privilege (it would be ridiculous to say this), but I have, as seen by myself.

Couldn't one assume that all those persons had a right to talk about what's seen who were being seen. I.e. all those who were one a picture could talk about the picture.

“But I can persuade myself that nobody else has pains even if they say they have, but not that I haven't.”   It makes no sense to say, that “I persuade myself that I have no pain” whoever says this. I don't say anything about myself when I say Ms-151,4 4 that I can't persuade myself that I haven't pain etc..

Can't I use the word “to see” in such a way that I call only this→ ‘seen’?”   But how do I act according to this decision? Do I, e.g. admit that someone else besides me can see it, or do I say that only I can see it?   Suppose everybody talked only about what we should now describe as ‘What's seen by me L.W.’. But they all know what I see; they don't ask me. And if anybody describes it wrongly we say that he can't doesn't speak properly, expresses himself wrongly. There is no such thing as deceiving somone about what I see. – Isn't there even then a temptation Can't I even then imagine a temptation to say, “I can only know what I see not what the others see?”?

It's no use ˇjust pointing ahead of me, & if, instead, I point to a description & tap both my chest & the description & say ‘I see this’ – it makes has no sense to ask “how do you know that it's you who sees it” for I don't know that it's this person & not another one which has sees before I point; but one could in certain cases say I know because I point. – This is what I meant by saying that I dont chose the mouth which says “I have toothache”.

Der, wenn ich so sagen darf, krankhafte Charakter des Solipsismus zeigt sich wird offenbarzeigt sich, wenn wir die Consequenz zu ziehen versuchen daß nur ich N.N. wirklich sehe, da wir vor dieser Consequenz sofort zurückschrecken. Wir sehen Ms-151,6 6. sofort, daß wir das gar nicht sagen wollten.

Isn't it queer that if I look & point in front of me & point in front of me & say “this!”, I should know what ˇit is I mean. “I mean just these shades of colour and shapes, the appearance.”

[Ein Wissenschaftler sagt er betreibe nur empirische Wissenschaft oder ein Mathematiker nur Mathematik & nicht Philosophie, – aber er ist auch den Versuchungen der Sprache unterworfen & muß sich wie jeder, er ist in der gleichen Gefahr wie jeder Andre & muß sich vor ihr in [A|a]cht nehmen.]

If I say “I mean the appearance”, it seems that, though I had sa[y|i]d ⌊am⌋ tell⌊ing⌋ you what it is I am pointing to at, or looking at, e.g. the chair as opposed to the bed, etc.. It is as though ˇby the word “appearance” I had actually directed your attention to something else than w e.g. the physical objects you are looking at. And indeed there corresponds a peculiar stare to this ‘taking in the appearance’. Remember here what people Philosophers of a certain s⌊c⌋hool Ms-151,7 7. used to say so often: “I believe I mean something, if I say ‘ …’”.

It seems that the visual image impression which I'm having is something I can point to; that I can say of it, it is unique. // … I can point to & talk about; // . That I am pointing to at the physical objects I am looking in my field of vision, but not meaning them but the appearance. This object I am talking about, if not to others then to myself. (It is almost like something painted on a screen which surrounds me)

This object seems to be ˇis unsuitably inadequately described as “that which I see”, “my visual image”, as it has nothing to do with any particular human being. Rather I should like to call it “what's seen”. And so far it's all right except that only now I've got to say what can be said about this object, in what sort of language game. “What's seen” is to be used. For at first sight one should feel inclined to use th[e|i]⌊s⌋ words expression as one uses a word designating a physical object & only on second thought I see it appears that I can't do that. – When I said Ms-151,8 8 that here seems to be an object I can point to & talk about, it was just that I was comparing it with to a physical object. For o⌊n⌋ly on second thought it appears that the idea of “talking about” isn't applicable here. (I could have compared the ‘object’ to a theater decoration.)

Now under when could I be said to speak about that this object? When would I say I did speak about it? – Obviously when I describe – as we should say – my visual image. And perhaps only if I described it, & only if I described it to myself.   But what is the point in this case o[t|f]o say⌊ing⌋ that when I describe to myself what I see I describe a an (peculiar) object called “what is seen”? Why talk of a particular object here? Isn't this due to a misunderstanding?

Imagine a game played on a kind of chessboard. You can extend the game to 64, 81, 100, etc. squares & the situation which is loosing in the 64-game is winning Ms-151,9 9 in the 81-game, loosing in the 100-game, winning in the 121-game etc.. What di If you are asked “what did ‘meaning what he said’ consist in” you will describe phenomena facts which however supplemented by ˇcertain other facts would be characteristic of his not meaning what he said, – and so on.

“Can I imagine 10101010 = μ [S|s]oldiers in a row?” “Can I imagine an endless row of [S|s]oldiers?”   Why shouldn't I say, I can imagine an endless row of soldiers? the image is something like a row the end of which I can't see & a gesture & the words “on & on for ever –” said in a particular tone of voice. And suppose I said: μ soldiers would reach from here halfway to the sun if we placed them a yard apart!? Isn't this too ‘imagining the row’?

It is a very remarkable & ˇmost important fact that there are numbers which we all of us should call “big large numbers”.

There is a particular way of explaining the sense (meaning) of an expression which we may call Ms-151,10 10

In philosophy we often say that people wrongly imagine a certain state of afairs, e.g. “they imagine that a law o⌊f⌋ nature in some way compels things to [p|h]appen”, ort “they imagine that it's a question of psychology how a person can know a certain fact whereas it is one of grammar” etc. etc.. But it is necessary in these cases to explain what it means “to imagine this so & so”, what kind of image is it they are using. It often sounds as though they were able to imagine the logically impossible & it is not easy to straighten out our description of the case & to say what ˇin this case they actually imagine.   E.g.: People treat the question “how do we know what so & so is the case” as a question of psychology which has nothing to do with the sense of the prop which we say is known. But first: where do they take this idea from, how do they come by it? Which ˇreally psychological question are they thinking of?   There Obviously there is a case in which the question “how does he find this out” is a personal &, perhaps, psychological Ms-151,11 11 one. “How did he find out that N was in his room?” – He saw him through the window or he was hidden under the bed. – “How did he find out that the glas was cracked?” He saw the krack with his naked eye or he saw it through the gl magnifying glass etc. We say he finds out the same thing in different ways & therefore not that what he finds depends upon how he finds it.   When do we say that he finds out the same thing in two ways? Imagine language games: somebody is asked a question “A?” & trained to answer “yes” if he sees a man person A in the next room, “no”, if he doesn't. In He is trained to answer ˇthe question “A?” by “yes” also if he hears A's voice from the next room. “What right have we to ask the same question in these two cases?” or “What right has he to use these two different tests to answer the same question?” Or, suppose someone asked: “Now are ⌊is⌋ th[e|i]se really one ˇ& the same question or do we have two different questions only expressed in the same words?”   Now concider the ostensive definition: “This man is called ‘A’” & ask yourself whether this definition tells us whether ⌊if⌋ we are to regard seeing A from a different Ms-151,12 12 side or in a different position or hearing his voice as criteria of him being there? – Here we are tempted to say: “But surely I just point to this man, so there can't be any doubt what object I am meaning!” But that's wrong though the doubt of course is not whether I mean this → or that ↘ thing.   One may say that the ‘object’ I am inclined to say I am pointing to ˇin the ostensive definition is not determined by the act of pointing but by the use I make of the word defined. And here one must beware of thinking that after all even if the pointing finger pointed to a different object in the sense in which the arrow     ⟶ A  B o  o      may be said to point to A [&| or] B, so that by a different way of pointing I might have distinguished the cases.   “But we conceive of objects, things, different from our sensedata, e.g. the table as opposed to the views we get of it.” But what does conceiving of this object consist in? Doesn't it is it a peculiar ‘mental act’ occuring whenever, say, we talk about the table? Isn't it using the word table in Ms-151,13 13 the game we do use it? using it as we do use it?

We are tempted to say that the word “toothache” is the ‘name of a feeling of which I don't know whether anybody except me ever has it’. But even I can be said not to know whether I always mean the same by this word.

“I always thought that holding one's cheek was having toothache; then he knocked out a tooth of mine, then I knew what ‘toothache’ meant”. Well what does it mean? – And Or what was it like “to know what ‘toothache’ means”?

“Now I know what ‘pain’ means”.

A faked moan ˇof pain isn't something necessarily a moan without something & a real moan ˇof pain a moan with something.

Aber wir möchten sagen: “die Begleitumstände sind andere”. Aber daran ist etwas Unrichtiges.

You say in one case the expression Ms-151,14 14 corresponds to the feeling experience. But how does it correspond?   Imagine, you were wrong about the correspondence, then what would remain? That you said these words & that you did not cheat, but now cheating & not cheating are not ‘private experiences’. It's no good saying “I recognize this experience as … ” as ˇ can say I don't know whether I recognize the experience of recognizing rightly.

We are using the word “to cheat” in two different ways. In one way whether I do it can be verified by the other person, in the other sense we say “only I know whether I cheat”.

“I knew all the time that I had cheated.”

Quite true, we distinguish simple acting & acting prompted by feeling, & feeling with expressing it expression. These are distinctions in our language. “But are you saying that all these distinctions are distinctions in mere behaviour?” –

Can one by multiplying 2 with itself reach obtain 12? Ms-151,15 15

“Mere behaviour”. “There is only behaviour” would seem to say that there was no life that we (or I) acted as automatons, as unconscious mashines.   I wish to say: “The difference between me & a mashine doesn't only just consist in the difference of our actions but in this that I am conscious & the mashine isn't”.   But oughtn't I say that this only distinguishes a machine from me not from a human being? For why shouldn't I say that the difference between a human being, animal, sewing machine, etc., lies in their actions, if I except myself. But then I dont even except my body.

“I know consciousness only from myself, I don't know whether anybody else is conscious has consciousness, but it makes sense to assume it & I do make the assumption in certain a class of cases.”

What worries us is the idea of ‘behaviour + [E|e]xperience’. – We might think that it was possible to talk of behaviour without ˇthere being experience. ‘Could I talk about moaning if there was no such thing as hearing the moaning?’ Or: Does Isn't talking of behaviour ¤ Ms-151,16 16

“I want someone to explain to me a certain game & to make it eas[y|i]⌊er⌋ I put the question to him: “tell me what a man does to winn the game.” Someone might say “I don't want to know what a man does to win it, this is a question about human beings; I want to want to know what the game is they play.”   The analogy we might be mislead by is this: you ask the question “   You ask, what does it mean that “a rod is 6 inches long”. Someone answers one finds [it|ou]t whether it is so by using a measuring rod divided into equal parts. “What does this mean?” – One divides it into equal parts in such & such a way. I have given a definition in terms of the way of verification. “But isn't this an indirect definition?” Sometimes it is, sometimes it isn't.   Sometimes how we look for something may determine what we are looking for, sometimes it doesn't. – We are always liable to think of the fact that we can find out that there is a chair here in many different ways & we forget that this is just conditioned by the particular use we make of the word “chair”, “table” & in general the generic names of physical Ms-151,17 17. objects. ⌊⌊ [s|S]upposing we said “what does it mean to have an enla⌊r⌋ged liver & someone answered “we ver[y|i]fy it by looking at the persons eye & seeing …” ⌋⌋   Describe an object by describing its use.   Describe an object by saying what hollow it fits into.   More ore less of it's use is expressed by different forms of a prop. Concider this! The sense of a prop is what you must know to understand it.   What does understanding a question consist in?   What does it mean to understand a mathematical question?   Would you understand ‘25 × 25 = ?’ if you didn't know how to calculate it? Would you say you understood the a position of a board game if you had no idea of the way the game was played? ˇAsk How much must you know to understand it? Would you not be inclined to say that you understand it more & more the more you knew about the game? But we could also imagine a case whe in which you would say that you understood the position even though you knew nothing didn't know the exact rules of the game, even if these rules had not yet been given!   Now concider such a question as “are there an inf. nr. of primes or not, Ms-151,18 18 & if not, how many?” I show you what we call a prime nr. & ask you if you understand this question. Prima facie you all say yes. Now I want to show you that you could also look at it from a different & perhaps more ‘exact’ point of view & say ‘no’. We have here a question but we have not yet got a method of it's solution & I want you to think of it in terms of 25 × 25 = ? when we don't know what multiplication is. Now I'll say (what I've said in a similar case before): The question for you gets it's sense by the idea picture of a small finite nr. of cardinals etc.. But what does that mean? In the case of the small nr of cardinals you have a method, you know what to do, here you don't know it, so how can what does it mean, that “the question gets it's sense from the case in which you do know it”? Our mind works on the line that there is something which hasn't yet been calculated which could but for our weakness be calculated it takes ˇno notice of the fact that we have no method & although this can't alter the facts it determines the way of expressing: We say we don't yet know so & so; & if someone shows Ms-151,19 19 us Euler's proof we say that now we know the answer to the question we have asked. But are we bound to express ourselves in this way? Can't I persuade you to adopt a different way of expressing ourselves of which too we can't say that it is inconsistent with the usual use of words? What if I say: This question i.e. the form of words was indeed suggested by the finite case, but the analogy just brakes down because there is no method of solution. Eulers “proof” needn't be conceived as answering the question “how many primes are there”.   This question might perfectly well be said to be nonsensical. (As e.g. “what colour has visual space.”). “But is it in our power to regard as question as nonsensical or as making sense? And what about Eulers proof?” Need we ask such a question as “how many cardinal numbers are there”? This question which seems in some way to get hold of the infinite i.e. the enormous for this reason might appeal to some of us & might, on the other hand, repell some of us, – e.g. me. Funeral Concider such a prop as: “There are as many squares as there are cardinals”. If we look at it like this: 1, 2, 3, 4, 5, 6, 7, 8, 9 … we should be Ms-151,20 20. inclined to say that there were less squares than cardinals; if we think of them as 1², 2², 3², 4², …, we shou say, there are as many. ⌊⌊ Thinking in terms of an analogy doesnt mean that this analogy is constantly before our mind. The Idea of finding out something about the series of cardinals. ⌋⌋ Why shouldn't we draw the conclusion that this whole question doesn't make sense? But we actually say that it does, & part of it's charm that the answer is in a way paradoxical adds ˇfor some to it's charm. (Some + some = some). It seems to us that we have discovered a new element with utterly different properties. I should like to get rid of this analogy. – Can “the heptagon be constructed?” – A “Now surely this question makes sense!” – B “Now surely this question makes no sense!” – What argument would A use: “you know what it means ‘to construct the pentagon, etc. hexagon, so … , ˇyou know what a heptagon is, what construction means”. B: “It makes no more sense to say ‘can the 7 gon be constructed’, than to say ‘can the 5-gon be constructed’. I know what we call ‘a constructed (as opposed to measured) pentagon’, I know what we call ‘the pentagon-construction’. We use this expression because of certain obvious analogies. But I don't [k|c]all anything heptagon construction. So don't ask such a question as can it be …. Compare this with the statement “on this animal's forhead there Ms-151,21 21. was a heptagon constr.’ – answer: I don't know what you're talking about. “But what about the proof that the heptagon can't be constructed? As there is such a proof, it is the answer to that question of which you say it makes no sense. “Must I conceive of this proof as the answer to that question?” When the proof is given I can say: you have now given the expression 13 gon sense & you have decided that the expression construction of the 7 gon is not never to be used at all’. Further you have now given the question: “can the 7 gon be constructed” sense, analogous to that can 735912 be devided by 19.

Now back to the question “how many 777 are there in π.” When I say that the case of the small first nr. gives this question its first meaning this is to say that our attitude towards this expression is due to it sounding like that other kind of question. Our attitude can however change if I now remind you of the cases I've just been talking about. Why should we ask this question? – “But don't mathaticians try to solve it , or similar questions?” Ms-151,22 22. Why should we call what they are doing “trying to solve this question”. Why should we not say they add new constructions to mathematics. Now concider this expression: “Surely, either there are n times 777 in π or not!” A) this is a tautology, B) if it means that you can't help yourself & must ask this question, I contradict you & say that you needn't look at it that way. – Now e.g. you say that the difficulty about that question is that the prop. “there are 777 in π” can only be proved in a general way, whereas the prop. ‘there are’ can be proved by finding a case of 777 in the deveopment. I should say let that teach you something about the sense of the question! Remember that a position or a move in a game gets its sense from the game. We are liable to get the idea that the mere form of words has something ◇ in it which we must find or of which we must say that we can't find it.   Now to the question “are there 777 in μ places”. “Surely there are, or there aren't”. This means nothing more nor less than “We know what it means to say Ms-151,23 23 ‘that there are’ or ‘that there aren't’. Now it is obvious that we can't straightforwardly say we know in this case what it means, because to explain what it means we should have to point to small numbers & why should I accept this explanation for μ? This is all without much interest as long as I dont actually set the task “find out about μ” for we could use μ as example though we never thought of answering the question with respect to μ! – But if now we try to find a new method of calculating the answer for μ then indeed we may ask ourselves in what sense we can be said to answer the old question, in what sense we can say that we've found a shortcut. It will depend on the method actually applied. Ask yourself: What are we to do if somebody actually calculated f(μ) by counting & found a different answer? I should say: to attribute it to human frailty ‘that we can't develope all places of π’ is just thoughtless, you wouldn't talk like that if you saw the use of your words clearly. But this is like saying: to say 0:0 = 1 is thoughtlessness you would not say so if … But one can never Ms-151,24 24 know this & someone might say this & we would respect it.   Contradiction.   What are we to say if someone tells us about a proof: “that all mathematical questions can be solved”.   One can use an appelation for a ‘proof’ without regarding it as the answer to a question.

¤⌊⌊⌋⌋ → … talking of experience & therefore talking what we call “talking of private experience” a special case of “talking about ‘behaviour’”?

Onem might put it by saying: “Experience is the at the bottom of everything we say about phenomena; so if we call anything in particular talking about ˇdirect experiences it must be ˇjust a special case of talking about phenomena as the ordinary way.

If we say “toothache is nothing but behaviour” we seem to say that it is not so & so, we seem to wish to exclude something., But that's obviously what we mustn't do. Ms-151,25 Our job is obviously not to reduce anything to anything, but only to avoid certain misleading ways of expression.

“Toothache is not a behaviour but an                   [E|e]xperience.” “We distinguish between ‘behaviours’ and ‘experiences’. “Dancing is a behaviour, [T|t]oothache an experience.” Th[i|e]s⌊e⌋ [is|are] grammatical statements. About the use of the words “dancing” & “toothache”.

(“This form of words seems to mean something but means nothing”. That is: We connect a certain image with this expression or we are inclined to use it because it sounds analogous to other expressions & we connect a certain at attitude, state of mind etc. with it; but if we then ask ourselves how we are going to use it we find that we have no use for it ore a use of a totally different kind from that, which we at first vaguely imagined[.| (]expected).)

First of all it seems that we are partial for ‘behaviour’ that we wish to explain everything in terms of it. [n|N]ow why should we be in th biased in this way? Is it because of some kind of materialisme? Ms-151,26 What ax have we to grind?

There is an ordinary (& unproblematic) way of using such a word as “toothache”, but we are inclined to give on philosophizing about it to give it a different use finding out however that we can then do away with it entirely because that proposed use ˇas a matter of fact makes it into a useless symbol.

“We use the expression ‘x has toothache’ when we see perceive a certain behaviour in others, or, on the other hand, when we ourselves have toothache”. What does it mean: “I say ‘I have toothache’, when I have feel toothache”? What does this explain? It could of course be an explanation in several ways: I say to someone: “Now if I have stomac ache I'll always say ‘I have toothache’ to in order to make Smith believe so & so”, “I won't l[y|ie] again, I will only say ‘I have t.” when I really have it.” or “I say ‘I have t’ when I feel a pain here (pointing)”.

I wish to say that we can't adduce the ‘private experience’ as a justification Ms-151,27 for expressing it.

We can't say “he is justified in moaning because he has pains” if we call pain the justification for moaning. – We can't say “he is justified in expressing pain, because he has pain” unless we wish to distinguish this case of being justified in expressing pains from another way of justification, e.g. that he is on the stage & has to act a sick man.

If I am tempted to say “my justification for moaning is to h having pain”, it seems I point – at least to for myself – to something which I express to which which I give expression by moaning.

The idea is here that there is an ‘expression’ for everything, that we know what it means ‘to express something’, ‘to describe something’. Here is a feeling, an experience, & now I could say to someone “express it!”. But what is to be the relation bet of the expression to what it expresses? In what way is this expression the expression of this feeling rather than another?! One is inclined to say “we mean this feeling by this expression”, but what is meaning Ms-151,28 th a feeling by a word like? Is this quite clear if, e.g., I have explained what ‘meaning this person by the name ‘N’’ is like?

“We have two expressions: one for moaning without pain, & one for moaning with pain.” To what states of affairs am I pointing as ⌊an⌋ explanations of these two expressions?   “But these ‘expressions’ [k|c]an't be mere words, noises, which you make, they get their importance only from what's behind them (the state you're in, when you use them)!” – But how can this state imp give importance to noises which I produce?   Suppose I said: The expressions get their importance from the fact, that they are used not used coolly but that we can't help using them. This is as though I said: laughter gets it's importance only through being a natural expression, a natural phenomenon not an artificial form of language. code.   Now what makes a ‘natural form of expression’ natural? Should we say: “An experience which stands behind it”? Ms-151,29

If I use the expression “I have toothache” I may think of it as ‘being used” naturally’ or otherwise[.|;] [B|b]ut it would be wrong to say that I had a reason for thinking either. – ‘It is very queer that all the importance of our expressions seems to come from that X, ˇY, Z, the private experiences, which for ever remain in the background & can't be drawn into the foreground.   But is a cry when it is a cry of pain not a mere cry?

Can one say: ‘If I teach the child the use (meaning) of the word toothache I can only hope that it really feels toothache, (or, that it feels real toothache) for if it doesn't then I've taught him a wrong meaning”?

Why should I say that the ‘expression’ derives its meaning from the feeling behind it, – & not from the circumstances of the lang. game in which it is used. For imagine a person crying out with pain alone in the desert: is he using a language? [S|C]ould we say that his cry had meaning?

We feel labour under the queer temptation to describe Ms-151,30 our language & its use, introducing into our description an element of which we ourselves say that it is not part of the language. It is a peculiar phenomenon of irridescence which seems to fool us.

“But can't you imagine people behaving just as we do, showing pain etc., etc. & then if you imagine that they don't feel pain all their behaviour is, as it were, dead. You can imagine all their behaviour with or without pain. –”

The pain seems to be the is – as it were – the atmosphere in which the expression exists. (The pain seems to be a circumstance.)

Suppose we say that the image I use in the one case is different from that which I use in the other. But I can't point to the two images. So what does it come to, to say this, except just ⌊to⌋ saying it, using this expression.   We are, as I have said, tempted to describe our language by not saying that we use certain elements, images, which however in the last moment Ms-151,31 we aga⌊i⌋n withdraw.

Isn't the word expression in it's use an image, – why do I refer back to an image which I can't show?

“But don't you talk as though (the) pain wasn't ˇsomething terribly real?” – Am I to understand this as a prop. about pain? I suppose it is a prop. about the use of the word ‘pain’; & it is one more expression, utterance, ˇan essential part of the surrounding in which we use the word ‘pain’.

Feeling justified in having expressed pain I may concentrate on the memory of pain.

Now what's the difference between using my expressions as I do but yet not using “toothache” to mean real pain & the proper use of the word? –

The private experience is to serve as a paradigme & at the same time we adm admitedly it can't be a paradigme.

The ‘private experience’ is a ˇdegenerate construction of our grammar (comparable in a sense to tautology & contradiction). And Ms-151,32 this grammatical monster now fools us: for when we wish to do away with it it seems to us as though we denied the existence of an experience, say, toothache.

What would it mean to deny the existence of pain?!

“But when we say we have toothache we don't just talk of behaving expressing toothache in this or that way!” – Certainly not, – we express toothache! ‒ ‒ ‒ ‘But you admit that the same expression behaviour may be the expression of toothache pain or may not be that.” – If you imagine a man cheating you always imagine him to use one expression secretely for himself & another for someone else, & this secrecy is not the ‘secrecy of priv. exp.’. ⌊⌊ Cheating is done secretely but this secrecy is not that of the ‘private experience’.⌋⌋ Why shouldn't it be concidered wrong in him to use language in this way.

We say “only he knows whether he says the truth or l[i|y]es.” “Only you can know if what you say is true.”   Now compare secrecy with the ‘privateness’ of personal experience’! In what sense is a thought of mine secret? If I think Ms-151,33 aloud it can be heard. – “I have said this to myself a thousand times but not to anyone else.”

“Only you can know what colour you seen” But if it is true that ˇonly you can know, you can't ever import this knowledge, nor can you express it.   Why shouldn't we say that I know better than you what colour you see if you say the wrong word & I can make you agree to my word, or if you point to the wrong sample etc.?

“I didn't know that I was lying.” – “You must have known!” –

⌊Examine:⌋ “If you don't know that you're having toothache, you arent havent got don't have toothache.”

“I don't just say ‘I've got toothache [a feeling]’, but toothache [a feeling] makes me say this.” (I deliberately didn't write ‘the feeling of toothache’, or ‘a certain feeling.)   This sentence distinguishes between, say, saying it as an example of a sentence, or on the stage etc., & saying it as an assertion. But it is no explanation of the expression Ms-151,34 “I have toothache”, of the use of the word “toothache”.

“I know what the word [“| ‘]toothache[”| ’] means, it makes me concentrate my attention on some one particular thing.” But on what? You're now inclined to give criteria of behaviour. Ask yourself: “what does the word ‘feeling’ or still better ‘experience’ make you concentrate on?”, “What ⌊is⌋ it like to concentrate on experience? If I try to do this I, e.g., open my eyes particularly wide & stare.

“I know what the word ‘toothache’ means, it produces one particular idea image in my mind”. But what image? – “I can't That can't be explained.” – But if it can't be explained what was the meaning of saying that it produced one particular image? You could say the same about the words “image” in your mind”. And all that it comes to is that you are using certain words without an explanation. “But can't I explain them to myself?” Or at least understand them myself without giving an explanation? Can't Ms-151,35 I give a private explanation? But is this anything you can call an explanation?” Is staring an ˇa private explanation?

But how does this queer delusion come about?!

Here is language, –, & now I think that I can embody I try to embody something in language as an explanation, which is no explanation.

We decide to call the say that the triangle a has half the area of the rectangle . Can't you imagine that the question how big is the area of the triangle should make no sense to you at all as you only talked of areas of rectang[el|le]s. One might be inclined to say, that the triangle had not really one particular area; perhaps that there was a series of areas which could be said to approach filling the triangle. Ms-151,36

Privacy of sensedata. I must bore you by a repetition of what I said last time. We said that peo one reason for introducing the idea of the sense datum was that people, as we say, somet⌊i⌋mes see different things, colours e.g. when the looking at the same object. Cases in which we say “he sees dark red objects whereas I see light red”. This We then are inclined to talk about an object other than the physical object which the person sees who is said to see the phys. obj.. It is further clear that we only gather from the other persons behaviour (e.g. what he tells us) what that obj looks like & so it lies near to say that he has this object before his mind's eye & that we don't see it. Though we can also say that we might have it before our mind eye as well without however knowing that it is he has it before his minds eye. The ‘sense datum’ ˇhere is the way the physical object appears to him. In other cases no phys object enters.   Now I must draw your attention to one particular difficulty about the use of the ‘sense datum’. We said that there were cases in which we should say that the person sees green what I see red. Now the question suggests itself: if this can be so at all, why shouldnt Ms-151,37 it be al[l|w]ays the case? It seems, if once we have admitted that it can happen under peculiar circumstances that it may allways happen. But then it is clear that the very idea of seeing red loses its use if we can never know if the other doesnt see something utterly different. So what are we to do: Are we to say that this can only happen in a limited number of cases? This is a very serious situation. – We introduced the expression that A sees something else than B & we mustn't forget that this had only sense use under the circumstances under which we introduced it. Concider the prop: “Of course we never know whether new circs wouldn't show that after all he saw what we see” Remember that this hole notion need not have been introduced. “But can't I imagine all blind men to see as well as I do & only behaving differently; & on the other hand imagine them really blind? For if I can imagine these possibilities then the question even if never answerable makes sense.” Imagine a man say W. now blind, now seeing & observe what you do? How do these im⌊a⌋ges give sense to the question? They don't & you see that the expression stands & falls with its usefulness Ms-151,38 “But I know The idea that the other person sees something else than I is only introduced because of to account for certain expressions; whereas it seems that this idea can exist without any reference to expressions. “Surely what I have he too can have.”   “And remember that we admit that the other may have pain without showing it!” So wh if this is conceivable, why not that he never shows that he has pain;” & why not that everybody has pain constantly without showing it; or that even things have pain?!” What strikes us is that there seem to be a few usefull applications of the idea of the other persons having pain without showing it & a vast number of useless applications, applications which look as though they were no applications at all. And these latter applications seem to have their justification in this that we can imagine the other person to have what we have & in this way the prop that he has toothache seems to make sense appart from any expression at all. “Surely”, we say, “[We| I] can imagine him to have pain or to see, etc..” Or “As I can see myself so I can imagine him to do the same”. In other words I Ms-151,39 can imagine him to play the same role in the act of seeing which I play. But does saying this determine what I mean by “he sees”?   We arrive at the conclusion that imagining him to have pain (etc.) does not fix thes sense of the sentence “he has pain”.   “He may all along mean something different by ‘green’ than I mean.” Evidence (Verification). But there is this consideration: “Surely I mean something particular, a particular impression & therefore he may have an other impression; surely I know what that would be like!” “Surely I know what it is like to have the impression I call ‘green’!” But what is it like? You are inclined to look at a green object & to say “it's like this!”. And these words though they don't explain anything to anybody else seem to be at any rate an explanation you give yourself. But are they?! Will this explanation justify your future use of the word ‘green’? In fact seeing green doesnt allow you to make the substitutions of someone else for you and of red for green.   “The sensedatum is private” is a rule Ms-151,40 of grammar, it forbids to use such expressions as “they saw the same sensedatum” it may (or may not) allow such sentences as “he guessed that the other had a sensedatum of this … kind”. It may only allow expressions of the form: “The other looked round, had a sensedatum and said …”. You see that the use of this word in such a case has no use at all.” But if you like to use it, do! –   “But surely I distinguish between having toothache & expressing it, & merely expressing it”; & I distinguish between these two in myself.” “Surely this is not merely a matter of using different expressions, but there are two distinct experiences!” “You talk as though the case of having pain & that of not having pain were only distinguished by the way in which I expressed myself!”   But do we always distinguish between ‘mere behaviour’ & ‘experience & behaviour’? If we see someone falling into flames & cr⌊y⌋ing out do we say to ourselves: “there are of course two cases …”? Or if I see you here before me do I distingu⌊i⌋sh?? Do you? You Ms-151,41 can't! That we do in certain cases doesn't show that we do in all cases. This to some of you must sound silly & superficial; but it isn't. When you see me do you see one thing & conjecture another? (Don't talk of conjecturing subconsciously!) But supposing you expressed yourself in the form of such a supposition wouldn't this come to adopting a ‘façon de parler’?   Can we say that ‘saying that I lie is justified by a particular experience of lying’. Shall we say ‘… by a particular priv. experience’? or ‘… by a part. priv. exp. of lying’? or ‘by a part. priv. exp. characterized in such & such ways’?   “But what, in your opinion is the difference between the mere expression & the expression & the experience?”

“Do you know what it means that W. behaves as he does but sees nothing; & on the other hand that he sees?”   If you ask yourself this & answer ‘yes’ you conger up some sort of image. This image is it seems derived Ms-151,42 from the fact of your seeing or not seeing (if you close your eyes) & by this derivation, it seems, it must be the picture we interpret to correspond to our sentence “he sees”, “he doesn't see”. – As when I substitute my body for his body & for holding a match holding a pen. – But substituting his body for my body might mean that my body has changed so as to be now like his, & perhaps vice versa. It seems a direkt & simple thing to understand “knowing thinking that he has what I have” but it isn'tt at all. The case is simple only if we speak e.g. of physiological processes. “I know only indirectly what he sees but directely what I see.” embodies an absolutely misleading picture. I can't be said to know that I have toothache if I can't be said not to know that I have toothache. I can't be said to know indirectely that the other has if I can't be said to know it directely. The misleading picture is this I see my own machbox but know only from hearsay what his looks like. We can't say: “I say he has t. because I observe his behaviour but Ms-151,43 I say that I have because I feel it”. (This might lead one to say that ‘t.’ has two meanings, one for me & one for the otherˇ being)   “I say ‘I have t’ because I feel it” contrasts this case with, say, the case of acting on the stage but can't explain what ‘having t’ means because having t = feeling t & the explanation would come to “I say I have it because I have it”. = I say I have it because it is true. = I say I have it because I don't ly. One wishes to say: In order to be able to say that I have t. I don't observe my behaviour, say in the miror. And this is correct, but it doesn't follow that you d[i|e]scribe an observation of any other kind. Moaning is not the description of an observation. ˇThat is You can't be said to derive your expression from what you observe. Just as you can't be said to derive the word ‘green’ from your visual impression but only from a sample. – Now against this one is inclined to say: “Surely if I call a colour green I don't just say that word, but the word comes in a particular way”, or “if I say I Ms-151,44 have toothache’ I don't just use this phrase but it must come in a particular way!” Now this means nothing for, if you like, it always comes in a particular way. “But surely seeing & saying something can't be all!” Here we make the confusion that there is still an object we haven't mentioned. You imagine there is a pure seeing & saying & one + something else. Therefore you imagine all distinctions to be made as between a, a + b, a + c, etc. The idea of this addition is mostly derived from considerations of our bodily organs. Wh All that ought to interest you is whether I make all the distinctions which you make: whether e.g. I dont disting⌊u⌋ish between [s|c]heating & telling the truth. – “There is something else!” – “There is nothing else!”. ‒ ‒ ‒ “But what else is there? – “[B|W]ell this→!”.   “But surely I know that I am not a mere automaton!” – What would it be like if I weren't? – “How is it that I can't imagine myself not seeing, hearing etc. experiencing?” – We constantly confuse & change about the comon sense use & the metaphysical use. Ms-151,45   “I know that I see.” –   “I see.” – you seem to read this off some fact; as though you said: “There is a chair in this corner.”   “But if in an experiment, e.g. I say ‘I see’ why do I say so? surely because I see!”   It is as though our expressions of personal experience needn't even spring from [c|r]egularly recurrent inner experiences but just from something.   Confusion of description & sample.

The idea of the ‘realm of consciousness’. Ms-151,46

Sir it is pathetic ridiculous to see all the discussion going on about the harmfulness of the gangster films to the young while the minds of both adults & children [is|are] being systematically poisoned by the foul worst kind of Vansitartt propaganda made by the ˇcinema newsreels newsreel comments in our cinemas, & condoned inspired by the M.O.P. Can there be anything more swinish foul evil than the gloating war news of the British Movietone News unless it be that of Universal News? The gloating over dead ‘Huns’ over the old German citys flattened razed to the ground over German civilians who walking about among the ruins of there towns? Everybody knows about Nobody doubts the unspeakable horrors of the Nazi Regime which are perhaps comparable only to … When they were in full swing long before the war had started & even after it had started we heard very little about them … Now Now that the enemy is completely finished to use the words all the well known tricks of the camera & the by far nastier ones of the commentators are set into action motion to make represent the German people to the unthinking cinema goer look appear like a as one pack of woolves. The commentators are worthy pupils of Dr Goebbels, of worst kind of Germans. We are not writing this letter in what Ms-151,47 would be a crazy expectation to open the eyes of the blind, but to direct the attention of the seeing to a horrid evil the lying propaganda the germ of Nazism itself.
