4.5 explained

Wittgenstein argues that it is possible to give the most general form of a proposition, which describes the essential structure of any proposition in a sign language.

What happens

Wittgenstein argues that it is possible to give the most general form of a proposition, which describes the essential structure of any proposition in a sign language. This form ensures that every possible sense can be expressed, and that any symbol falling under the description can express a sense given appropriate name meanings. The existence of a general form is proven by the fact that no proposition's form could be unforeseen; the general form is 'Such and such is the case.'

Themes in this chapter

  • General Form of Proposition

    Wittgenstein asserts that a general form of proposition can be given, describing the essence of all propositions, and that this form is 'Such and such is the case.'

Characters to notice

  • Mr. Wittgenstein

    Presents the possibility and necessity of a general form of proposition.

Key passages

  • The general form of proposition is: Such and such is the case.

    Every proposition ultimately asserts that a certain state of affairs obtains.

    This encapsulates Wittgenstein's view that all propositions share a common logical structure.
