Philosophical thought is living, and to deny it the space to change, based on some dogmatic belief in the great men of communism, is unscientific. Any attempt to force this non-change, also, will condemn your movement 
to ultimate failure. The success of Marxism-Leninism in the past is on account of its place in time, its then-relevance, which has since the rise of neoliberalism, and of the now nearly complete project of globalization been made, and do not think I will say obsolete now, only foundational. In the place of this Marxist-Leninist dogma, people now, who are in friendlike familiar relationship with philosophy, art and science, and who are learned in the workings of our modern world, must breathe life into the dying discipline of Marxist philosophy, which you so-called communists have condemned to death.
