 The details of the response will depend on how the connectives we have written as ‘\(\vee\)’ and ‘\(\wedge\)’ are interpreted; in the absence of contraction, each of conjunction and disjunction comes in ‘additive’ and ‘multiplicative’ flavours, and different proponents of noncontractive views differ in which of these they acknowledge. The difference between additive and multiplicative conjunction is this: an additive conjunction can do the work that either of its conjuncts can do, while a multiplicative conjunction can do the work that both of its conjuncts can do together. In the presence of contraction, the additive conjunction suffices for the multiplicative: it can be used once to fill the role of the first conjunct and again to fill the role of the second conjunct. Contraction allows these two uses to count as one. Without contraction, though, the additive conjunction need not suffice for the multiplicative. (The multiplicative conjunction suffices for the additive in the presence of a structural rule called weakening, not otherwise discussed in this article.) The situation for disjunction is dual: in the presence of contraction, the additive disjunction suffices for the multiplicative, but it need not otherwise.
