    The world is all that is the case.
    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.
    2.0211 If the world had no substance, then whether a proposition had sense would depend on whether another proposition was true.
    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.)
    2.0211 If the 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). 2.023 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. 2.024 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.

  • 早期维特根斯坦的逻辑图像论
    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.)
    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.
    2.224 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.

  • 逻辑 与 先天、
    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.
    3.04 If 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 if its truth were recognizable from the thought itself (without anything a to compare it with).
