Niels Bohr introduced the concept of complementarity in order to give a general account of quantum mechanics, however he stressed that the idea of complementarity is related to the general dificulty in the formation of human ideas, inherent in the distinction between subject and object. Earlier, we have introduced a development of the concept of complementarity which constitutes a new approach to the interpretation of quantum mechanics. We argue that this development allows a better understanding of some of the paradigmatic interpretational problems of quantum theory. Within the scheme proposed by modal interpretations we analyze the relation between holism and reductionism as well as the problems proposed by Arntzenius and Clifton. We discuss the problem of presupposing the concept of entity within the quantum formalism and bring into stage the concept of faculty as a way to recover the objective character of quantum mechanics.
