Abstract
The aim of this article is to present the assumptions of Nietzsche's critique of the notion of “truth” that allow to consider his “perspectivism” an excellent critical and epistemological alternative to philosophy of science. It takes place, therefore, an interpretation of the Nietzschean expressions “tragedy”, “tragic knowledge”, “life”, “perspectivism” and “truth”. Nietzsche seems to be convinced that the belief in the notion of “truth” cannot be consistent with “life”, since “life” is also “tragedy” and therefore cannot be reduced to a concept. On the other hand, the notion of “truth” found in natural science seeks to consolidate a concept about reality, which nullifies the plurality of perspectives on life. Thus, an analogy between this aspect behind Nietzsche's perspectivism and the construction of scientific knowledge allows us to consider that the construction of scientific knowledge needs to disregard the notion of truth and to consider all the individual perspectives of scientists – science must not seek truths but metaphors or perspectives on “life” – which allows to show an excellent contribution of Nietzsche to the debates about the notion of truth in the philosophy of science.
