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.
