Although the thought of Humanitarian Dialectics put forward by Markovich, the theorist of Neo_x005fMarxism in Eastern Europe, is complicated and full of multiple views, it still has sources which can be traced and referred to. It is mainly connected with three theoretical sources. The theoretical basis of Markovic’s Hu? manitarian Dialectics is formed by carrying on classical Marxist writers’thoughts of dialectics, using the human? istic standpoint of Western Marxism and selecting theoretical resources from Neo-Marxism of Eastern Europe. This lays the theoretical framework of its creativity of thought, rationality of argumentation and possibility of practice, giving it a certain sense of revolutionary innovation of the times.
