Wittgenstein

let's start with Vidkun spies Vic consign himself is one of the strangest people of the 20th century he was born into the second wealthiest family in austria-hungary just behind the Hapsburgs he lived in Vienna youngest of nine children if you've got if you google bit consign house you will find many different houses because the vision sign family owned a palace Indiana but then also houses all over Austria friends of the family included the sculptor Auguste Rodin famous for the thinker and painter Gustav Klimt composers prams and Mahler and so he was very well connected not only the people of immense power and wealth in austria-hungary but also to people who were really the center of austro-hungarian culture he was home-schooled until he was fourteen very much to a Technical School one of his classmates was Alf Hitler ah Benny studied engineering in Berlin and Manchester at 22 he got unhappy with engineering and decided he wanted to study logic so he went to Cambridge to study with Bertrand Russell and then later he taught of Cambridge who took of her cheeky mores chair will find out more about more later Russell described it consign is absurd and perverse but I think not stupid later he became convinced the fit consignment was an unparalleled genius in any case he was on he taught for a wild Cambridge he served in the First World War um with the austro-hungarian army he spent many years been living in a Norwegian fishing village uh he worked as a gardener for a while hey he taught all a mentor II school in a remote Austrian village where it was very difficult for him to keep his identity secret but he did his best he was known for being incredibly strict with the students he taught them mathematics for two hours every morning first thing and if they did anything wrong he would yell at them child of them and even swap them so imagine having him as your first grade teacher okay Jonny what's one plus two oh two No anyway we're going to be talking today about his first great work the Tractatus logico-philosophicus it is well an odd work is you probably seeing it's just propositions better fact there's a joke from John Cleese and a Fawlty Towers episode come on man this is not a proposition from Vidkun Stein the model of the books is taken from pure burger all that we know that isn't just rustling and roaring and be threat settle in three words and indeed the book really by its own light is meanings by the time you get to the end the moral is everything absolutely lose meaning okay but only now have you got the point where you can see that it's meaningless yes no he summarized the book this way what can be said can be said clearly what Kennedy said must be passed over in silence and it turns out that a lot that he really cares about has to be passed over in silence the logical empiricists of the vienna circle rudolf carnap curdled a number of others were inspired by vick and science work they thought he was one of them they saw his work as a logical empiricist work Russell did too victus I'd hated Russell's introduction of the truck Tom thought he had got it completely wrong the vienna circle invited fit consigned to speak before them he came up before the group they expect him to give a paper on logical analysis and the nature of the world and language and thought and salah instead he turned his back to them and read poetry now they were mystified by this it just added to his reputation as a crazy person but actually i think it related this last point there are certain things he's maintaining it can be shown that cannot be said and so the point of reading poetry before the group is to say look I'm not saying that all that other stuff stuff is nonsense I'm saying that actually the most important things in life we can't really articulate we can't even ask the question let alone pose an answer but that doesn't mean it is an important that doesn't mean it isn't there and so we have to show it art can do that music can do that um poetry can do that the trek tops maybe to do that but he didn't think ordinary language could do it well what is this book really about it's about the relationship between mind and world it's about the relationship really between thoughts and let this circle represent the mind and take that as being a thought okay I don't know what that's supposed to be but it's just something okay that indicates something happens in the mind it's a thought and there is yes we might say the cat drinks water from the glass and there is my cat's a dog drinking water from my glass something happens frequently in my house I get myself some water sitting on the table before I can drink any the cup drinks it okay well always this nap usually over the cat in any case okay so that's what we want to understand the sentence the cat drinks water from the glass the thought which has that as something like its content and then this is the fact in the world well actually what you see here is a picture of the fact in the world we're going to be interested in pictures and the ways in which language and caustic things here's the traditional view as formulated for example by Aristotle the world consists of what of things okay of people like you and me of objects like chairs and tables and cameras of maybe microparticles scientific type objects like I don't know electrons fields things like that that's what the world consists of and the traditional philosophical terminology those things are called substances so the idea is the world consists of substances those substances have certain properties for example the camera is black or my shirt is striped they also stand in relations I am wearing my shirt where the camera is on the tripod they have a location in space and time cameras over there and my shirt is right here they do things and have things done to them and so all of those things you might say are ordinary ways of categorizing the world in fact Aristotle describes all this in a work called the categories he just says here's what it said look at language there were nouns that refer to people places and things then there are verbs that say what they do or what is done to them and then their adjectives that describe their properties there are all sorts of things like prepositions that refer to their relations and then we have various ways of expressing their location in space and time and so on and so really he says if you look at the structure of language and its grammatical categories they match on two very nicely the categories of things in the world well 15 Stein is really denying this right the outset but he does maintain a deeper point that Aristotle is also maintaining it is the correspondence theory of truth will meet it a number of times in the course the idea here is that thoughts and utterances are true when they correspond to reality so I say the cat drinks water from the glass and that is true if and only if well there's a corresponding fact you might said the cat is actually drinking water from the glass now actually I've cheated a bit by saying the cat drinks water during the simple present in English is complicated it's not in most languages but in English it is so actually you might think that sort of means it literally or frequently routinely drinks from the glass so on here pretend that it's a sports reporter okay they often use the simple present in a way that just says it's happening now okay so one of my favorite examples Winfield's going back back he Rams his head against the wall it's rolling toward second base well the ball was rolling told second based on his head but anyway that's he you know knows we fields going back actually has cheated ghost window goes back goes back he hits his head in the wall it's rolling towards second place the simple present there he hits his head against all means happens right there so ignore in other words all the complexities of tense to the moment so the idea is just you look at this it's true if and only if something like that is going on the work that object really does stand in that relation to that other object that object really does have that property that object really is doing that thing and so well look at Vidkun stein right at the beginning you can read it here in German if you want or in English he starts out by saying the world is all that is the case and he elaborates he says the world is the totality of facts not of things now when I took a seminar on Vic and science track Thomas we spent entire to a nap session on just those two propositions I don't recommend that but here's the idea he's trying to say don't think of it the way Aristotle did don't think of the world as consisting of objects that have properties and say innovations think of the facts this object standing in that relation to that other object the fact of this object having that property in other words don't think about the world consisting of the shirt and the camera and the table and so on think about the world is consisting of the shirt it's being front or the cameras being black yes for me speaking good okay those are facts those are the things he wants to think of the worlds consisting of why well really he's motivated by the correspondence theory he says when is a sentence or a thought true when there is a corresponding fact I say the cap drinks water from the glass and there it is the Caddy is drinking water from the glass notice the cap isn't enough to make that sense true the glass isn't enough it requires that a certain relationship hold between them and that is what he says this making sentences true or false so think in terms of facts not of things yeah what if you said like the blanket is comfortable is that fact like because it depends on like if somebody could think it's time somebody not so is it a pact or is it true or false or good the blanket is comfortable it's not a fact well okay it is attributing a property to it the question is is that a simple property or is it a relational property is it comfortable for you um yeah it might be a fact for you or really the way Vic and some say yeah look don't be a relativist about this instead just think it's a relational property being comfortable so you might say that's comfortable that really means the relationship between it and me Brutus is comfort in me or something like that and so think of it as really relational there are lots of things like that if I say for for that is large that actually has a sort of hidden relational element it doesn't look like and yet you might say look that's a large rat somebody says well rats are animals so I guess that's a large animal no a large rat is still kind of a small animal and so there's a kind of hidden relational part to that and I think comfortable is like that what do you say that's comfortable or actually my earlier example that's yummy you're really kind of mean from his point of view that you find it yummy you find it comfortable so there's this hidden term that is explicit in the sentence now that points out something important which is that we're going to act later as if the terms of sentences and the terms of thoughts and then the things in the world all neatly correspond to each other but notice they're comfortable that's a great example there we've got something that's left out in the font and left out in the sentence but really seems like it has to be part of it in the world to make this make any sense and so we're going to find places where there isn't a very nice one-to-one correspondence here which complicates his picture and maybe even with use it he's going to think no no really um there's this exact match oh but maybe there's not if we go on and look at the further propositions the world is determined by the facts and by there being all the facts so what do I need to know to describe the world exactly I just need to list the facts but then also to say and that's all the facts okay I can't just list the facts and you want well is that the complete story or not I have to say at the end and that's all there is the totality of facts determines what is the case and what is not the case the facts in logical space are the world the world divides into facts so the world really is made up of facts don't think if the world is consisting of all these things think of the world as something like a big list of facts okay really it's not just a list of course of facts it's this come some complex combination of facts that brings us to the second proposition what is the case a fact is the existence of states of affairs I can think of a fact as being something like the cap drinking water from the glass but I can describe that as a muscle thing without it being natural right when I took the photograph that was actually happening the cat actually was doing it so that state of affairs was actually but if I describe it now I didn't leave any water well I didn't they have their water bowls but there was no blasts of water reflection my house so now it's false it's a possible state of affairs that a cat would be drinking water from a glass in my house right now but it's not that there was question yeah yeah yeah yeah yeah so okay good if you think about these this thing save affairs the actual facts you're right there are infinitely many of them so this is going to be an infinite collection the world will be an infinite collection of facts but then if we think of the merely potential states of affairs the facts that could obtain um that could be any configuration of objects at all I feel impossible so if I start telling a story I say ah yes once upon a time I had a class just like this and we decided that when we got to Klein later and he talks about jungle linguist we couldn't really understand it without going to the jungle and finding some wild tribes who spoke a completely unfamiliar language and so we did that and we ventured through the jungle a mountain lion leaped out at us luckily one of the students had an iPad and threw it like a frisbee and took the head of a bottom line right okay now this did not happen good but the possible state of affairs right an extremely remote since Paris you might take but nevertheless a possible state of affairs so there are infinitely many of these state of affairs that really exists that really are actual and then they're infinitely many more that are just merely possible well bit consign advances what is called the picture theme that's his basic idea of how thought represents the world and how language represents the world here's the idea we picture facts to ourselves if I describe that the students throwing the iPad and beheading the mountain lion or just thinking about my right now there could be there isn't but there could be a glass of water that are kind of shrinking from you can picture those right you can imagine those things and I've represented them in speaking to you I've had the thought and so I've represented it in thought so we have different ways of representing these facts we can represent them in thought we can represent them in language we can represent them in photographs or images or paintings or things like that now what is a picture whether it's a sentence that's kind of picture or thought is a kind of picture for vitcon Stein but then there are physical pictures like photographs and paintings drawings and so on what do they like well they're really models of reality they are an indication of how some part of reality is if they're true if they're accurate or how it could be but is it if they are inaccurate or false well in a picture objects have the elements of the picture corresponding to you so go back to that picture with the cat drinking water from the glass there are elements of the picture there's the image of a cat that represents that corresponds to the actual cat Zadok and then there is the glass of water it course be a bit the picture the sort of image there at the glass of water course wants the actual glass of law so the idea is that in a picture the elements of the picture represent the objects well so far you might just say yeah yeah boring boring right and there are times when I read the tract on us and I just think oh this is obvious okay there's nothing very exciting going on but notice what he say this is something he thinks is true not just up for example a photograph or a draw but it's something that's true of thought it's something that's true of language so a picture even if it's really a sentence where compass is going to have some logical pictorial form there must be some form by virtue of which that depicts what it depicts so if we think back to that photograph of the cat drinking the water there is some form by virtue of which it represents a cat drinking water right and it's not too surprising there's something in it that looks like a cat but there's something that looks like a glass of water it gets more complicated if we think about abstract if I say Oh cut drinking water I'll draw about half drinking water yeah yeah it's not bad oh that's better than most of my art I study drawing and painting for an entire year when I was an undergraduate my teachers thought I was good I thought they were insane I thought it was a terrible but many case um yeah if I fight virtue of what my net represent half drinking water right type of cat drinking water then you can slogan that's its head yes that's the tail these must be legs and here's the bowl of water in fact it looks kind of like a fish bowl doesn't you sort of expect a goldfish oh so anyway that's something that you could sort of deal with and say alright there's something that looks very vaguely like a cat it gets more complicated if I just give you something ha-have water looks like some Chinese character a B uh yeah then you well okay I don't get it I don't see why that represents anything and that's because it doesn't have a pictorial form by virtue of which it seems to be able to represent them so here's this novice study move if we're thinking of pictures in terms of drawings or paintings or photographs it's easy to see what he has in mind but then he says a proposition is a picture of reality so if I simply say the cap drinks water from a glass that's something that actually also depicts in something like this sense it also has parts that represent and have a certain form that allows them to represent the captain the water in the glass well a proposition is true and here I'm not quoting this is just I think the general idea it's true if it maps on to the world if there's a way of taking certain elements of that picture of that proposition of that sense of that thought and saying that map's advocat that maps out of the water that maps out of the glass and those stand in a relationship that corresponds in some way to the relationship they read standing in the world so here's our basic picture we can find elements in that proposition but cat oh that's for response to the cat they dock and then water that corresponds to what's in the glass and then the glass that corresponds to the glass and then we can say ah drinks a drinks B from Z that's the basic relation well indeed that relation is holding there the cat is drinking water from the glass okay so we can actually see how their various parts course off well the picture theory then is actually a pretty simple way of thinking about this it's not new to bit consign it's something that acquires for example in the Middle Ages held and so it's not really a new thought at all in fact once you identify it this way it seems almost humdrum so why do we get anything interesting out of that well first of all he says a logical picture of X is a thought in the case of a photograph we can say well I understand what's happening this part of the image that sense of a cat and so on in a sentence I don't have too much trouble saying oh the words the cat represent the cat but now in a thought what represents well it's not physical thing anymore it's something more abstract he says there's a logical picture okay going on with thought and what is the thought well it's a proposition with sentence a significant proposition a proposition that has a meaning so if you want to think of it this way a thought is a corresponds to a way the world is or could be but it's a little more complicated than that language he says disguises thought and partly we've got the problem already identified then it might be that language leaves out certain things that really have to be there in the world like but like it being comfortable for me but there are other ways in which the form of language doesn't really match the form of thought we use language for all sorts of other purposes and so think about the ways in which we use language he talks about this much later much more in his later work where it really is designed for other purposes other than just depicting the way the world is I've got some temple sit escape from castle pick inside brightly the joke hey senior center don't forget remember dessert wake up let's go early for daleks turned out well notice that's not just depicting the world right i mean don't forget remember to turn wake up all of those are commands right in one way in which I can be doing something other than depicting the world is commanding so I can use language for that there are other things I don't know what this is doing this is a Chinese restaurant in Dalian and it's entitled romantic land and art life buzz so I'm not sure what I guess it's supposed to be beautiful and romantic is the idea sighs it's somewhat confusing to an ego speaker here's an old Viking poem which soul of a woman whose ways are false it's like sledding over slippery ice with unshod horses off control badly trained two year olds who are tripping rudderless on the rough sea or catching a reindeer with a crippled fan on a fine hillside fame up to tears so the Vikings had their problems too here is someone singing someone singing isn't necessarily trying to describe the world I mean they might be they might be telling a story or what have you but they might not be there aren't that many singing bass players so when I saw her in and there are 70 female bass bass players either so I saw somebody singing and playing the bass in Copenhagen it was a woman I had to get that picture oh here this actually happened on campus yesterday although this is a picture of the same thing happening in Denmark the signs say free hugs and there were these people just giving free hugs at the bus station her yesterday was happening just out in front ya know I'm free hugs were very bad Ella's suppose you go to Starbucks and you say unlike a canola latte well you're you're not really you know you're not really mean to describe the world you're asking for something right you might go in tena say I worked at Starbucks so I'm sort of at here at a Vic inside you say I would like a vanilla latte that's it yeah but you would you actually want me to do something right you're trying to ask for something you don't love you're not just making an observation about the world or here bring me another beer huh similar type of thing these are in downtown Austin I don't know what they mean focus one point and breathe or let's pretend more robots Spence about the description of the world that's an exhortation so pride or here's a quarterback calling an audible he's not describing things I mean he could be he could say be say wait a minute I see the linebacker over there right but no that's not what he's doing he's just calling out of play so it's sort of a command or here he's going hut hut that's why the description of the world right I mean bit concise isn't gonna say but that's false I'm sorry um or here are the cheerleaders shouting Texas fight or what-have-you that's an exhortation that's not really up description of anything here are the fans cheering again I don't know what they're saying but it's not likely to be a description of the world huh you can imagine the language this guy was using when as part of that it probably wasn't a description of the world so in any case what about philosophy lots of language doesn't really describe the world's doing other things so that means we shouldn't think the form of thought and the form of language are just the same nevertheless he thinks for certain purposes they're analogous enough that we can use language to understand thought what about philosophy well it aims at the logical clarification of thoughts he says it's not a body of doctrine but an activity so the philosopher isn't really describing the world what would a philosopher describe I mean scientists describe the world historians describe the world but philosophers what would be our sphere of activity to scribe well summer says it's a matter of seeing how everything sort of fits together in this big picture well maybe we can do that but Vidkun Stein says look really philosophy is about clarification it is about logical amounts it is about what do you mean let's try to get clear on this what kind of thing is really going on here but it isn't it really has languages its focus and thought it's focused not the world at all he says philosophies job is to set limits to what can be thought and in doing that to what can't be thought it's gotta set limits in that way by working outward through what can be it will signify what can't be said by presenting clearly what can be said so he's giving you a picture of you a here of what you can actually clearly say and clearly think and then what must lie beyond those bounds of language our job is to you might change rob a perimeter draw the fence and say within this sphere we can actually say meaningful things like the cat is drinking water from the glass that's a meaningful description but most philosophy isn't like that he thinks most philosophy to the extent that it tries to talk about the world is engaging in something that has nothing to do with facts the realist for example says some facts about the world or mind-independent and Vidkun sign will say that's not a description world I don't understand um the idealist says no every fact is my dependent again big concern will say hi I don't get what are you talking about fifth you're not talking about the cap drinking water you're not talking about something in the world you're making this big global pronouncement about the whole world he said ah I don't get it so his claim is everything that can be thought all can be thought clearly everything that can be put into words can be put clearly and this philosophies job helped do that what is a proposition well he says it's a truth function of elementary propositions if this were a logic course have now proceeded to talk for quite a while about this since it isn't I won't all say there are certain basic things that allow us to combine propositions to form other propositions in the dropped August words like and I can say the cap is on the table and is drinking water from the glass or I can say the cat is on the table or asleep on the so not I can say the cat is not drinking I've learned how to get the cat to stop drinking water but a lemon or a lime in it doesn't happens like so the cat is not drinking the water because I put the liner or some some cat is on the table all all the cats are asleep so we can construct sentences out of those from these atomic things about objects standing in simple relations and so but that's all vacant side then says something dramatic he says the limits of my language mean the limits of my world logics pervades the world the limits of the world are also its limits so the world has fundamentally a logical structure not too much after this Rudolf Carnap a member of the Vienna circle wrote a book called the logical structure of the world their location of both event the play the idea is indeed the world has a logical structure fundamentally and we can determine what that structure is by examining language this has a number of consequences one of the interesting ones the world of a happy man is a different one from that of the unhappy man here's the happy man here's the unhappy man here's Pitkin Stein now we could take this in a number of ways is he arguing for realism the limits of the world limits by language we could take it that way you might think they're fast they're states of affairs the objects that make them up and that's independent of what I think or say about them but limits what I can think or say because I've got to restrict myself to saying things about them you could take all this in a realistic way or you could take it in an idealist way all right is he saying that the limits of my language determine the limits of my world most people have actually thought that's what he means that does seem to express idealism what there is depends on my language and what my language is depends on my thought and so actually thought is determining the world and everything ends up being dependent on the mind well officially Vick in size position is these are both meaningless cleiton okay neither they're both nonsense these are metaphysical and according to the truck toss itself all bad kind of philosophy is utterly means there's no fact to which they could correspond so in a letter to his publisher he said what's most important in this book is what I couldn't I didn't and couldn't say and indeed by the end he says the track Thomas is meaningless you've gotten this far in the book you realize none of the propositions I've written down here like the world consists of facts novel things none of those actually have truth values none of them are descriptions of facts in the world so there are actually all meanings but he said nevertheless they have a use they're like a ladder you can use climb to the point where you see that their meaning is and then you can kick them away so they do something to you even though they're strictly speaking meaningless they show you something even if they have literally safe well what is left out a bunch of things get left out can't be reconstructed in this way the whole sense of the world you say what's the meaning of it all okay what's the question yeah he said there is no question there is no meaning to it all if you take the whole world and say it doesn't all depend on the mind or is it all really real independently of us or it has this meaning or it's all good or it's all bad he just says that those are not propositions in the world you can't ask about the totality of the world and formulate any meaningful proposition about it so any sense any meaning that the world has has to lie in some sense an outsider in the world everything is it's the cat is on the table the cat is drinking water in the glass so that happens does that happen there is no value in the world is it good or bad that it happens that's not something in the world okay and if there were values they would have no value he says so is the world good is the world bad that's not something that's it there in the world itself so he says there can't be any such things as propositions of ethics what is just for unjust right or wrong good or bad what you want to do ought not to do all of that is strictly speaking meaningless it can't be put into words other things end up being beyond the bounds necessity and possibility beyond what warrant anyway counterfactuals like if this were the case then that would be the case causation actually I she didn't use the word because few moments ago but you can't use the word becuase that's about combination is true functional attitudes John thinks this hey Sally knows that Bob wants that Freddie is afraid of blah blah blah those can't really fit in even they're not true function yeah it doesn't it's part of what must be passed over in silence you look at the horror of the First World War and can you actually say anything about it no you can Pat you can show it you can show somebody a picture you can write a poem but can you actually describe it can you say that was horrible no you cannot actually articulate now it seems like I just did that right I said that was horrible but he said that fast meaningless that doesn't describe a fact in the world so he says in the end some of the Gribble of the meaning of life he says the riddle doesn't exist and that self is the answer now includes what we cannot speak about we must pass over in silence yeah and Arthur Pryor at Oxford criticized it this way what have you said can't be hinted that either which I love it anyway so there's silence
