The article is mainly based on Tadeusz Czeżowski’s publication – “Metaethical considerations”, prepared to be printed but never published. This publication, however, is not a handbook of classical metaethics but a kind of generalization of ethical theories ordering in a way, all known until now ethical systems within philosophy. Thus, Czeżowski does not offer his metaethics as a section of traditional ethics but also as a kind of generalization of all ethics until now, and therefore, all systems worked out within (...) itself. In its essence “Metaethical considerations” is the concept of scientific ethics, regardless of anything that does not pass verification, subject of which are e.g. empirical science research results.
