5.24

An operation shows itself in a variable; it shows how we can proceed from one form of proposition to another.

It gives expression to the difference between the forms.

(And that which is common the the bases, and the result of an operation, is the bases themselves.)

5.241

The operation does not characterize a form but only the difference between forms.

5.242

The same operation which makes "q" from "p", makes "r" from "q", and so on. This can only be expressed by the fact that "p", "q", "r", etc., are variables which give general expression to certain formal relations.
