|Definition: determination of the use of linguistic signs (words, symbols, connectives) for non-linguistic or linguistic objects. New definitions are not supposed to be creative, that is, they are to be derived from the use of the signs already employed. See also definability, conservativity, systems, theories, models, reference systems, context definition, explicit defnition, implicit definition.|

|Holz I 38
Definition/Leibniz: the number of definitions is just as infinite as the number of terms and the axioms.
The definition always has the form of an identical sentence A = B. i.e. the predicate is identical with the subject.
One page can always be set for the other.
Substitution: Leibniz calls this interchangeability "making an insight through the consequences".
This is beside the proof of reason. Both must come together.
