Abstract

One of the crucial issues of modern universalistic theories of practical philosophy is the theoretical justification of normative principles and moral judgments that enables their universal validity. The problems these theories face are caused by separating rational theorizing from contexts of real life. That is the separation of theoretical justification and practice. The common for modern practical philosophy opposition between universalism and contextualism is reinterpreted today, new theories of post-metaphysical universalism appear that provide the developments of the last universalistic project of discourse ethics in the context of a critical theory of the “third generation”. The purpose of this article is to present the ethical philosophy of Hannah Arendt as the original conception where the Kantian theory of judgment and the Aristotelian notion of phronesis are brought together in order to clarify the nature of ethical and moral statements. This problem, as the article highlights, lies in the understanding of subsumption of particular under universal. Universal judgments according to Arendt are justified in the Kantian theory of “enlarged mentality” as the human capacity to interact in communication and activity. The sensitivity to situations is reflected in the Aristotelian notion of phronesis. As Arendt’s justification of normative and ethical judgments is analyzed, the hermeneutic character of her theory is revealed, which is appropriate for the theory of J. Habermas and modern followers of critical theory. The article provides additional insight into the concept of “public space” as the realm which enables the overlapping of theory and practice. As proved the “public space” in the practical philosophy of Hannah Arendt becomes the realm of mutual ethical and moral thinking where judgments are oriented to the level of the human condition in general. The paper concludes by arguing that Arendt’s conception may overcome the opposition between universalism and contextualism, which is relevant in current ethical discourse.
