摘要：This work intends to present in summarized order the defense of an ethic of responsibility in the approaches of Hans Jonas and Karl-Otto Apel. Despite agreeing on the problems emerging in our time and the urgent need for a universal ethic and looking to the future of humanity, the authors follow divergent paths in their formulations. It is necessary to put the perspective in which each arises in dealing with the problem. As for Jonah's concern is to offer a more concrete answer or practice, Apel tries to resolve the problem first at the theoretical level. Even following different paths, are two contemporary perspectives that purport to offer an answer to the problems of our time. We need to clarify whether proposals are incompatible or have traces of complementarity.
