If I want to understand something, I must observe, I must not criticize, I must not condemn, I must not pursue it as pleasure or avoid it as non-pleasure. There must merely be the silent observation of a fact.
I wouldn't want to live if I did not have my work. In any case, it's good that I'm already old and personally don't have to count on a prolonged future.
The receptivity of the masses is very limited, their intelligence is small, but their power of forgetting is enormous. In consequence of these facts, all effective propaganda must be limited to a very few points and must harp on these in slogans until the last member of the public understands what you want him to understand by your slogan.
