The article attempts to raise a question and give an answer to it regarding the evaluation of the philosophical creativity of Hermann Cohen, the German-Jewish thinker of the late XIX - early XX century. Moreover, following the philosophical style of Cohen himself, the question posed and discussed in the article is not idle, but it contains a hypothesis that forms our answer in a certain way. It is important to identify the difficulties and intellectual determinants that prevent the formation of a clear and unambiguous answer. At the same time these difficulties contain an initiating moment for opening a philosophical debate. The historical and philosophical reasons that make the very beginning of the discussion of the question more complex, are considered. The article, of course, cannot claim to be an exhaustive answer on such a fundamental topic, which is contained in the designated question. But the article itself, and the articles following it in the section devoted to the work of Herman Cohen, may be indicate that the time for this discussion has come.
