Tractatus Logico-Philosophicus by Ludwig Wittgenstein Published (1922) (Logisch-Philosophische Abhandlung (1921) Perhaps this book will be understood only by someone who has himself already had the thoughts that are expressed in it-or at least similar thoughts.-So it is not a textbook.-Its purpose would be achieved if it gave pleasure to one person who read and understood it. The book deals with the problems of philosophy, and shows, I believe, that the reason why these problems are posed is that the logic of our language is misunderstood. The whole sense of the book might be summed up the following words: what can be said at all can be said clearly, and what we cannot talk about we must pass over in silence. Thus the aim of the book is to draw a limit to thought, or rather-not to thought, but to the expression of thoughts: for in order to be able to draw a limit to thought, we should have to find both sides of the limit thinkable (i.e. we should have to be able to think what cannot be thought). It will therefore only be in language that the limit can be drawn, and what lies on the other side of the limit will simply be nonsense. I do not wish to judge how far my efforts coincide with those of other philosophers. Indeed, what I have written here makes no claim to novelty in detail, and the reason why I give no sources is that it is a matter of indifference to me whether the thoughts that I have had have been anticipated by someone else. I will only mention that I am indebted to Freges great works and of the writings of my friend Mr Bertrand Russell for much of the stimulation of my thoughts. If this work has any value, it consists in two things: the first is that thoughts are expressed in it, and on this score the better the thoughts are expressed-the more the nail has been hit on the head-the greater will be its value.-Here I am conscious of having fallen a long way short of what is possible. Simply because my powers are too slight for the accomplishment of the task.-May others come and do it better. On the other hand the truth of the thoughts that are here communicated seems to me unassailable and definitive. I therefore believe myself to have found, on all essential points, the final solution of the problems. And if I am not mistaken in this belief, then the second thing in which the of this work consists is that it shows how little is achieved when these problem are solved. L.W. Vienna, 1918 1 The world is all that is the case. 1.1 The world is the totality of facts, not of things. 1.11 The world is determined by the facts, and by their being all the facts. 1.12 For the totality of facts determines what is the case, and also whatever is not the case. 1.13 The facts in logical space are the world. 1.2 The world divides into facts. 1.21 Each item can be the case or not the case while everything else remains the same. 名师资料总结 - - -精品资料欢迎下载 - - - - - - - - - - - - - - - - - - 名师精心整理 - - - - - - - 第 1 页，共 47 页 - - - - - - - - - 2 What is the case-a fact-is the existence of states of affairs. 2.01 A state of affairs (a state of things) is a combination of objects (things). 2.011 It is essential to things that they should be possible constituents of states of affairs. 2.012 In logic nothing is accidental: if a thing can occur in a state of affairs, the possibility of the state of affairs must be written into the thing itself. 2.0121 It would seem to be a sort of accident, if it turned out that a situation would fit a thing that could already exist entirely on its own. If things can occur in states of affairs, this possibility must be in them from the beginning. (Nothing in the province of logic can be merely possible. Logic deals with every possibility and all possibilities are its facts.) Just as we are quite unable to imagine spatial objects outside space or temporal objects outside time, so too there is no object that we can imagine excluded from the possibility of combining with others. If I can imagine objects combined in states of affairs, I cannot imagine them excluded from the possibility of such combinations. 2.0122 Things are independent in so far as they can occur in all possible situations, but this form of independence is a form of connexion with states of affairs, a form of dependence. (It is impossible for words to appear in two different roles: by themselves, and in propositions.) 2.0123 If I know an object I also know all its possible occurrences in states of affairs. (Every one of these possibilities must be part of the nature of the object.) A new possibility cannot be discovered later. 2.01231 If I am to know an object, thought I need not know its external properties, I must know all its internal properties. 2.0124 If all objects are given, then at the same time all possible states of affairs are also given. 2.013 Each thing is, as it were, in a space of possible states of affairs. This space I can imagine empty, but I cannot imagine the thing without the space. 2.0131 A spatial object must be situated in infinite space. (A spatial point is an argument-place.) A speck in the visual field, thought it need not be red, must have some colour: it is, so to speak, surrounded by colour-space. Notes must have some pitch, objects of the sense of touch some degree of hardness, and so on. 2.014 Objects contain the possibility of all situations. 2.0141 The possibility of its occurring in states of affairs is the form of an object. 2.02 Objects are simple. 名师资料总结 - - -精品资料欢迎下载 - - - - - - - - - - - - - - - - - - 名师精心整理 - - - - - - - 第 2 页，共 47 页 - - - - - - - - - 2.0201 Every statement about complexes can be resolved into a statement about their constituents and into the propositions that describe the complexes completely. 2.021 Objects make up the substance of the world. That is why they cannot be composite. 2.0211 If they world had no substance, then whether a proposition had sense would depend on whether another proposition was true. 2.0212 In that case we could not sketch any picture of the world (true or false). 2.022 It is obvious that an imagined world, however difference it may be from the real one, must have something- a form-in common with it. 2.023 Objects are just what constitute this unalterable form. 2.0231 The substance of the world can only determine a form, and not any material properties. For it is only by means of propositions that material properties are represented-only by the configuration of objects that they are produced. 2.0232 In a manner of speaking, objects are colourless. 2.0233 If two objects have the same logical form, the only distinction between them, apart from their external properties, is that they are different. 2.02331 Either a thing has properties that nothing else has, in which case we can immediately use a description to distinguish it from the others and refer to it; or, on the other hand, there are several things that have the whole set of their properties in common, in which case it is quite impossible to indicate one of them. For it there is nothing to distinguish a thing, I cannot distinguish it, since otherwise it would be distinguished after all. 2.024 The substance is what subsists independently of what is the case. 2.025 It is form and content. 2.0251 Space, time, colour (being coloured) are forms of objects. 2.026 There must be objects, if the world is to have unalterable form. 2.027 Objects, the unalterable, and the subsistent are one and the same. 2.0271 Objects are what is unalterable and subsistent; their configuration is what is changing and unstable. 名师资料总结 - - -精品资料欢迎下载 - - - - - - - - - - - - - - - - - - 名师精心整理 - - - - - - - 第 3 页，共 47 页 - - - - - - - - - 2.0272 The configuration of objects produces states of affairs. 2.03 In a state of affairs objects fit into one another like the links of a chain. 2.031 In a state of affairs objects stand in a determinate relation to one another. 2.032 The determinate way in which objects are connected in a state of affairs is the structure of the state of affairs. 2.033 Form is the possibility of structure. 2.034 The structure of a fact consists of the structures of states of affairs. 2.04 The totality of existing states of affairs is the world. 2.05 The totality of existing states of affairs also determines which states of affairs do not exist. 2.06 The existence and non-existence of states of affairs is reality. (We call the existence of states of affairs a positive fact, and their non-existence a negative fact.) 2.061 States of affairs are independent of one another. 2.062 From the existence or non-existence of one state of affairs it is impossible to infer the existence or non-existence of another. 2.063 The sum-total of reality is the world. 2.1 We picture facts to ourselves. 2.11 A picture presents a situation in logical space, the existence and non-existence of states of affairs. 2.12 A picture is a model of reality. 2.13 In a picture objects have the elements of the picture corresponding to them. 2.131 In a picture the elements of the picture are the representatives of objects. 2.14 What constitutes a picture is that its elements are related to one another in a determinate way. 2.141 A picture is a fact. 2.15 The fact that the elements of a picture are related to one another in a determinate way represents that things are related to one another in the same way. Let us call this connexion of its 名师资料总结 - - -精品资料欢迎下载 - - - - - - - - - - - - - - - - - - 名师精心整理 - - - - - - - 第 4 页，共 47 页 - - - - - - - - - elements the structure of the picture, and let us call the possibility of this structure the pictorial form of the picture. 2.151 Pictorial form is the possibility that things are related to one another in the same way as the elements of the picture. 2.1511 That is how a picture is attached to reality; it reaches right out to it. 2.1512 It is laid against reality like a measure. 2.15121 Only the end-points of the graduating lines actually touch the object that is to be measured. 2.1514 So a picture, conceived in this way, also includes the pictorial relationship, which makes it into a picture. 2.1515 These correlations are, as it were, the feelers of the pictures elements, with which the picture touches reality. 2.16 If a fact is to be a picture, it must have something in common with what it depicts. 2.161 There must be something identical in a picture and what it depicts, to enable the one to be a picture of the other at all. 2.17 What a picture must have in common with reality, in order to be able to depict it-correctly or incorrectly-in the way that it does, is its pictorial form. 2.171 A picture can depict any reality whose form it has. A spatial picture can depict anything spatial, a coloured one anything coloured, etc. 2.172 A picture cannot, however, depict its pictorial form: it displays it. 2.173 A picture represents its subject from a position outside it. (Its standpoint is its representational form.) That is why a picture represents its subject correctly or incorrectly. 2.174 A picture cannot, however, place itself outside its representational form. 2.18 What any picture, of whatever form, must have in common with reality, in order to be able to depict it-correctly or incorrectly-in any way at all, is logical form, i.e. the form of reality. 2.181 A picture whose pictorial form is logical form is called a logical picture. 2.182 Every picture is at the same time a logical one. (On the other hand, not every picture is, for example, a spatial one.) 名师资料总结 - - -精品资料欢迎下载 - - - - - - - - - - - - - - - - - - 名师精心整理 - - - - - - - 第 5 页，共 47 页 - - - - - - - - - 2.19 Logical pictures can depict the world. 2.2 A picture has logico-pictorial form in common with what it depicts. 2.201 A picture depicts reality by representing a possibility of existence and non-existence of states of affairs. 2.202 A picture contains the possibility of the situation that it represents. 2.203 A picture agrees with reality or fails to agree; it is correct or incorrect, true or false. 2.22 What a picture represents it represents independently of its truth or falsity, by means of its pictorial form. 2.221 What a picture represents is its sense. 2.222 The agreement or disagreement or its sense with reality constitutes its truth or falsity. 2.223 In order to tell whether a picture is true or false we must compare it with reality. 2.224 It is impossible to tell from the picture alone whether it is true or false. 2.225 There are no pictures that are true a priori. 3 A logical picture of facts is a thought. 3.001 A state of affairs is thinkable: what this means is that we can picture it to ourselves. 3.01 The totality of true thoughts is a picture of the world. 3.02 A thought contains the possibility of the situation of which it is the thought. What is thinkable is possible too. 3.03 Thought can never be of anything illogical, since, if it were, we should have to think illogically. 3.031 It used to be said that God could create anything except what would be contrary to the laws of logic.The truth is that we could not say what an illogical world would look like. 3.032 It is as impossible to represent in language anything that contradicts logic as it is in geometry to represent by its coordinates a figure that contradicts the laws of space, or to give the coordinates of a point that does not exist. 名师资料总结 - - -精品资料欢迎下载 - - - - - - - - - - - - - - - - - - 名师精心整理 - - - - - - - 第 6 页，共 47 页 - - - - - - - - - 3.0321 Though a state of affairs that would contravene the laws of physics can be represented by us spatially, one that would contravene the laws of geometry cannot. 3.04 It a thought were correct a priori, it would be a thought whose possibility ensured its truth. 3.05 A priori knowledge that a thought was true would be possible only it its truth were recognizable from the thought itself (without anything a to compare it with). 3.1 In a proposition a thought finds an expression that can be perceived by the senses. 3.11 We use the perceptible sign of a proposition (spoken or written, etc.) as a projection of a possible situation. The method of projection is to think of the sense of the proposition. 3.12 I call the sign with which we express a thought a propositional sign.And a proposition is a propositional sign in its projective relation to the world. 3.13 A proposition, therefore, does not actually contain its sense, but does contain the possibility of expressing it. (The content of a proposition means the content of a proposition that has sense.) A proposition contains the form, but not the content, of its sense. 3.14 What constitutes a propositional sign is that in its elements (the words) stand in a determinate relation to one another. A propositional sign is a fact. 3.141 A proposition is not a blend of words.(Just as a theme in music is not a blend of notes.) A proposition is articulate. 3.142 Only facts can express a sense, a set of names cannot. 3.143 Although a propositional sign is a fact, this is obscured by the usual form of e
