Marxism is an interpretation of history which explains the progress of society as a product of the expansion of the forces of production of the material means of life, that is, the development of economy.

What remains constant for me, during the last 15 years, has been the conviction that the cold war was a calamity for the entire world, and that it can be justified by no consideration of theory, nor by any supposed national interest.

This radical transformation of world power relationships reflects primarily in the case of both the USA and the USSR the growth of the productive forces.

But I made no efforts to organize my supporters to hold on to the apparatus. Consequently I was soon expelled and my followers, who did not change coats overnight, quietly left or were expelled from the party.

Marxism conceives of the new system of socialism as the necessary outcome of all previous history made possible and necessary only by that previous history.

I have opposed the Communist cold war line ever since, both by public utterance and by private help to trade unionists breaking free from the Communist influence.

The American Communists had thrived as champions of domestic reform.
