|Connectives: connectives are also called logical connectives or logical particles. E.g. and, or, if, then, if and only if. Negation also counts as a connective. See also truth value table, truth table.|

Interpretation/Putnam: is not a representation, but production. - E.g. classical connectives are not represented using the intuitionistic connectives, but the classical theorems are produced. - Putnam: the meaning of the connectives is still not classic, because these meanings are explained by means of provability and not by truth. - Change of meaning: e.g. assuming we wanted to formulate Newton's laws in intuitionistic mathematics, then we would have to limit the real numbers (for example, on the 30th decimal).
Then, in the classical theory, the connectives would refer to "provability in B1" and in the other to "provability in B2". Then the connectives would change their meaning when knowledge changes.
Realism/Putnam: the realistic conception of connectives ensures that a statement is not solely true because it follows a (any) theory.
Ideal Assertibility/PutnamVsPeirce: no "ideal limit" can be specified reasonably - not to specify any conditions for science - PutnamVsKuhn: if you do not believe in convergence but in revolutions, you should interpret the connectives intuitionistically and apprehend truth intra-theoretically.
Truth/Logic/Putnam: the meaning of "true" and the connectives is not determined by their formal logic ->holism ->Quine: the distinction between the entire theory and individual statement meanings is useless.
