4.121 explained

Wittgenstein argues that propositions cannot represent logical form; rather, logical form mirrors itself in propositions.

What happens

Wittgenstein argues that propositions cannot represent logical form; rather, logical form mirrors itself in propositions. Language cannot represent what it expresses—it shows the logical form of reality.

Themes in this chapter

  • Picture Theory of Language

    Propositions are pictures of reality; they show logical form without representing it.

  • Limits of Language and Thought

    Language cannot express its own logical form; what is shown cannot be said.

Characters to notice

  • Mr. Wittgenstein

    Author of the proposition; presents the distinction between showing and saying.

Key passages

  • Propositions cannot represent the logical form: this mirrors itself in the propositions.

    Statements cannot depict the underlying structure of logic; that structure is reflected in them.

    Logical form is shown, not represented.

  • That which mirrors itself in language, language cannot represent.

    What is reflected in language cannot be put into words by language.

    The showing/saying distinction.

  • The propositions show the logical form of reality. They exhibit it.

    Propositions display the logical structure of reality; they do not describe it.

    Emphasis on showing versus saying.
