Show Summary Details


Frege, Peano, and Russell all shared what we now call elementary logic. Nowadays we think of this as given mainly by its criterion for validity, i.e. truth in all interpretations. But they were more concerned with elaborating its rules of proof. For illustration, the chapter gives an axiomatic set of rules, such as Frege and Russell used, though it does not reproduce their own versions. They did not think of the formulae of logic as schemata, open to many different interpretations.

Keywords: Russell; Frege; Peano; elementary logic; validity; axiomatic presentation; schemata in logic
