In the post war period I began again to have my doubts about Russian policy.

I went first to France and then to England, where I studied and at the same time I tried to make a serious study of the bases of Marxist philosophy.

I was a student in Germany when Hitler came to power.

At this time I had complete confidence in Russian policy and believed that the Western Allies deliberately allowed Germany and Russia to fight each other to death.

The Communist Party said that I must finish my studies because after the revolution in Germany people would be required with technical knowledge to take part in the building of the Communist Germany.

I went first to France and then to England where I studied and at the same time I tried to make a serious study of the basic Marxist philosophy.

Shortly after my release (from detention as an enemy alien) I was asked to help Professor Peierls in Birmingham, on some war work.

My argument was that we could not stop Hitler by cooperating with other bourgeois parties but that only a united working class could stop him.

I was lucky because on the morning after the burning of the Reichstag I left my home very early to catch a train to Berlin for the conference of our student organization and that is the only reason why I escaped arrest.
