The article analyses various contemporary codes of scholar ethics which seem to concentrate on minor and pathological problems of scholar’s work (such as plagiarism) and pass over the crucial and universal moral principles of intellectuals. Instead, the article offers the alternative set of ethical rules, which refer to classical Aristotelian moral philosophy as well as to medieval Parisian university tradition. The author underlines such values as worth of truth, reliability of research and moral equipment of the scholar. These values constitute the basis of sketching “scholar’s Decalogue”, i.e., ten principle rules, which should be kept and obeyed by every scholar and scientist.
