What happens

Wittgenstein discusses how the same operation that transforms one proposition into another can be applied repeatedly, and that this is expressed by treating propositions as variables that reveal formal relations.

Themes in this chapter

  • Logical Atomism

    The operation on propositions reflects the logical structure underlying language and reality.

Characters to notice

  • Mr. Wittgenstein

    Author of the Tractatus, presenting the formal nature of operations on propositions.

Key passages

  • The same operation which makes “ q ” from “ p ”, makes “ r ” from “ q ”, and so on.

    The operation that transforms one proposition into another can be applied iteratively.

    Illustrates the formal recurrence of logical operations.

  • This can only be expressed by the fact that “ p ”, “ q ”, “ r ”, etc. , are variables which give general expression to certain formal relations.

    The repeated application of an operation is captured by treating propositions as variables that show formal patterns.

    Emphasizes the role of variables in expressing general logical forms.
