This study presents a systematic treatment of the critical rationalism of the German philosopher Hans Albert, a follower of Karl R. Popper. On the basis of an analysis of his key works (Traktat über kritische Vernunft, Die Wissenschaft und die Fehlbarkeit der Vernunft, Kritischer Rationalismus, Kritische Vernunft und Rationale Praxis etc.) the eight main methodological tenets of his philosophical conception are presented. They are: 1. universal criticism, 2. consequentialist fallibilism, 3. methodological revisionism, 4. critical realism, 5. theoretical pluralism, 6. constructive metaphysics, 7. the postulate of a single method of science, and 8. a proposal of a way of life. In reference to each of these tenets, the author explains the intellectual tradition in contrast to which Albert defines his own position and, at the same time, considers several critical objections to Albert’s assumptions. The study thus provides a relatively complex view of the subject-matter in question.
