Abstract
The materialist interpretation of history dogmatically resolves all histories into one. Marx and Engels themselves thought philosophy progresses toward the ultimate truth of Marxism, and implicitly held all historical positions interesting since their development reveals contradictions generated by inadequacies. Bolshevik Marxism's official ideology does not include philosophy's dissolution. Marxist definitions of philosophy emphasizing correct conclusions neglect distinctively philosophical argument and method. The recent Soviet view of philosophy's history has changed from the history of superstructure to the history of conflicting materialist and idealist theories, thereby conceding the centrality of philosophical ideas rather than trying to reduce them to class or economic interests.
