AJust like Henryk Struve said, the history of positivism is a gradual turn from Comte to Kant. When, at the beginning of 1880s positivism in Warsaw goes through a philosophical crisis, there are attempts to save it by expanding epistemology issues introduced from Neo-Kantianism. The influence of Marburg's school on Polish positivists is well known and widely described. In her article, the authoress is concerned with a different aspect of Kantianism; a project presented by the philosopher in 'Critique of Practical Reason'. It is a piece which had never been translated before 1902 or quoted during the period and which surprisingly corresponds with an important trend in the 19th century's reflection on Ethics.
