The moral philosophy of Nurettin Topçu bears some characteristics not fitting general and classical patterns. In the form he tries to systematize, “rebellion ethics” is primarily a matter of existence. Therefore, ethics is perceived not only as a practical but also and after all as an ontological and epistemic issue. The first step of the rebellion ethics is the “sincerity crisis”. The resolution of this crisis composed of the quest for an absolute truth both in the inner and the external world can not be found in the constantly changing finite/phenomenal world. Thus, the love of eternity, the second step, develops. This love stimulates a person and achieves progress in three courses: Art, ethics and religion. Surely, religion is the absolute necessity and the last stage/station. The final point is to understand the unity of existence completely and perfectly and to live so.
