 Accordingly, the meaning of the statements in a dialogue does not lie in some external semantic, but is immanent to the dialogue itself, i.e., in the specific and appropriate way the players interact. (This is linked to the Wittgensteinian conception of meaning as use.) The rules are the same for the two players and the meaning of the connectives is therefore independent of who uses them. This is why the rules are formulated using the variables \(\mathbf{X}\) and \(\mathbf{Y}\). Recall that the symbols “!” and “?” are used for statements and requests, respectively.
