An examination of the major motifs of dissident political literature from Poland, Czechoslovakia, East Germany, and Hungary in the 1970s reveals a certain commonality of understanding and suggests that dissent is itself a complex, multicausal phenomenon likely to pervade the region for some time to come. Criticisms of the existing system are based on a rejection of dictatorship and its concomitant intellectual rigidity, economic inefficiency, and social alienation. The dissidents' vision of a better socialist society, in contrast, is one of decentralized decision making and of plural centers of power operating within the context of respect for human rights. The tactics put forward by the dissidents derive from these ideas: open discussion, mass mobilization within a legal framework that respects the rights of minorities, and pressure on established elites to make the necessary changes.
