Tonk/Prior/Read: Do not introduce the link first and then assign meaning. - That cannot have the consequence that another pair of statements is equivalent.

Important argument: analytic validity cannot show that.
Re III 269
The meaning, even that of logic links, must be independent of and be prior to the determination of the validity of the inference structures. - BelnapVsPrior: (pro analytical validity): Must not define into existence, first show how it works.
Re III 271
Classical negation is illegitimate here. >Negation- Negation-free fragment. - Peirce's law: "If P, then Q, only if P, only if P".
Re III 273
ReadVsBelnap: the true disagreement lies beyond constructivism and realism. - Belnap's condition (conservative extension) cannot show that the classical negation is illegitimate.
>Negation.

Hoyningen-Huene II 56
Connectives/Hoyningen-Huene: You sometimes read that the truth tables would define the conncetives, i.e. clearly specify them. This is correct if one interprets the connectives in a very specific mathematical sense (namely as illustrations of two statements in the set true, false).

If, on the other hand, one understands the connectives as extensional statement links, i.e. as operators that form a new statement from two statements, then the truth tables do not define the connectives.
II 66
Binding strength of the connectives: increases in the following order: ,>, v, ∧.
II 113
It makes sense to attribute equality and difference to the propositional logical form, because the compelling force of propositional logical inference depends on them.
For the same reason, it makes sense to assign the connectives to the propositional logical form.
