The aim of this study was to use ethical arguments to strengthen the relationship between the concepts of legitimacy and evaluation. The analysis is based on the ethics of Levinas and Buber and is motivated by a sense of responsibility using dialogical ideology as a mediator. The main questions in this study consider the following: Does caring science as an independent academic discipline have the moral responsibility to develop a theory for evaluating the quality of basic research? and Will such (...) a quality evaluation theory have a reasonable probability of introducing legitimization into caring science? On an ethical level, this study introduces a meaningful interaction inspired by social demands and is linked to the concept of research justification. Legitimization turns from an abstract idea to an achievable entity by an act. The act of evaluation has the likelihood of delegating legitimacy and empowers the foundation of caring science, which in turn will become a cornerstone of nursing. At this stage there is no intention to develop an evaluation theory, rather to create a meaningful discussion for the future development of an ethics-based theory. (shrink)
