In this paper I demonstrate the selected problems concerning the relation between ethics and axiology of Nicolai Hartmann and ethics represented by Immanuel Kant. There are following questions: 1. the mode of existence of value; 2. the position of moral obligation in the structure of value; 3. the plurality of moral and axiological systems; 4. God and the moral character of human action; 5. Kantian practical reason and the real individual person as the subject of morality; 6. the problem of negative and affirmative freedom. Analysing these problems I endeavour to prove that the concrete relation between Hartmann and ethics of Kant modifies depending on considered detailed problem.
