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.
Shortly afterwards my father told me that he might be going into the Eastern Zone of Germany. At that time my own mind was closer to his than it had ever been before, because he also believed that they are at least trying to build a new world.
Since that time I have had continuous contact with the persons who were completely unknown to me, except that I knew they would hand whatever information I gave them to the Russian authorities.
I had therefore, no hesitation in giving all the information I had, even though occasionally I tried to concentrate mainly on giving information about the results of my own work.
I think the one thing that most stands out is that my father always did what he believed to be the right thing to do and he always told us that we had to go our own way even if he disagreed.
The world is a dangerous place, not because of those who do evil, but because of those who look on and do nothing.
Let every man be respected as an individual and no man idolized.
Any man who reads too much and uses his own brain too little falls into lazy habits of thinking.
If people are good only because they fear punishment, and hope for reward, then we are a sorry lot indeed.
Anyone who has never made a mistake has never tried anything new.
