In his contribution, Christoph Seibert deals with the question of whether homo religiosus exists as homo ethicus under aspects of individual ethics. Ultimately, he is concerned with determining the relationship between the religious and the ethical. He begins with the thesis that believing or religious people also have an ethical self-understanding, i. e. they see themselves as ethical subjects. He raises the question of whether ethical action is not ultimately the result of trying to live a religious life or seriously implementing religion in everyday life. While the coherence of this thesis with regard to European development cannot be denied in his opinion, he considers the question of a possible generalization or universalization to be worth investigating. The author chooses a methodological perspective that analyzes the religious and the ethical with regard to the individual. He defines the ethical as a phenomenon mainly characterized by strong normative distinctions (good/evil, just/unjust). The author considers it necessary to take the individual at the center as a fundamental ethical category in itself in order to develop an elementary understanding of the ethical. To make this possible, Seibert seeks to produce a concept of the self that allows us to understand the self as a fundamentally ethical task, and for this purpose considers it plausible to tie his considerations in this regard to the thoughts of the Danish philosopher Sören Kierkegaard (1813-1855), as the theme of the self and self-realization runs through the entire work of this thinker. In his article, Seibert seeks to answer the question of whether homo religiosus lives as homo ethicus using a specific interpretation of Kierkegaard, whereby he establishes the link to religion in Kierkegaard’s work.
