Nowadays, anyone who wishes to combat lies and ignorance and to write the truth must overcome at least five difficulties. He must have the courage to write the truth when truth is everywhere opposed; the keenness to recognize it, although it is everywhere concealed; the skill to manipulate it as a weapon; the judgment to select those in whose hands it will be effective; and the running to spread the truth among such persons.
Bertolt BrechtThe aim of science is not to open the door to infinite wisdom, but to set a limit to infinite error.
Bertolt BrechtThe first time it was reported that our friends were being butchered there was a cry of horror. Then a hundred were butchered. But when a thousand were butchered and there was no end to the butchery, a blanket of silence spread. When evil-doing comes like falling rain, nobody calls out "stop!" When crimes begin to pile up they become invisible. When sufferings become unendurable the cries are no longer heard. The cries, too, fall like rain in summer.
Bertolt Brecht
