The participants of the round table, noted West European Marxists and bourgeoise experts analyse the causes and consequences of the collapse of the East European systems. They try to find the difference between Marxism and „Marxism-Leninism", the Leninist and social democratic basis of interpreting Marxism and its relative truth. They do not only see the decay but also the unexpected emergence of the revolutionary activity of the masses, the possibbility of the development of a new left wing unity which does not simply mean identification with social democracy.
