The subject of my thesis is the relationship between ethics and metaphysics in the works of Marijan Cipra. The research is motivated by the parallelism between the idea of the primacy of practical in the introduction of the second edition of Cipra’s Metamorphoses of Metaphysics and the opening of the oldest system of German Idealism which situates any future metaphysics in the sphere of morality, of ethics. The presupposition of my thesis is coherence and continuity of Cipra’s philosophical works which is understood to be a spiritual biography of Marijan Cipra himself in the form of his concept of self-manifestation. The thesis moves from Cipra’s late writings, of which Thoughts on Ethics are the most important, over to his central work Metamorphoses of Metaphysics, all the way to his early papers “Contemplation and Act” and “On the Genesis of Human History”. My aim is to show how Cipra throughout his work treats this issue coherently. At the same time, whilst analysing the relationship between theory and practice, I am also addressing Cipra’s continuous focus on the idea of the necessity of metamorphosis of metaphysics into its anthropohanic guise. Finally, I am showing how a relationship with the spirit of Christianity as the condition of any future metaphysics does not leave Cipra’s original philosophical insight, and continues to be present in his main work, his PhD thesis, because a thought of direct contact of mind and divine is the leitmotif of his philosophy and his life.
