 The previous section presented the standard dialogical framework in the Lorenzen and Lorenz tradition. Different logics can be expressed within this framework, they can thus also be compared (e.g., classical and intuitionistic logic, and modal logics). Different objections have been raised against the standard framework, as the three objections presented below attest; various answers have been given by logicians interested in the dialogical perspective, often abandoning the Lorenzen and Lorenz tradition 1 in order to build a framework most appropriate to their own purposes (for other objections and their answer, see Rückert 2001).
