On my wall hangs a Japanese carving, / The mask of an evil demon, decorated with gold lacquer. / Sympathetically I observe / The swollen veins of the forehead, indicating / What a strain it is to be evil.

To those who do not know that the world is on fire, I have nothing to say.

Hungry man, reach for the book: it is a weapon.

What kind of a crime is the robbing of a bank, compared to the founding of a bank?

Near my bed, to my pain / The last thing at night, the first thing in the morning, / Of their victories and of my cares, /Promise me not to go silent all of a sudden.

You little box, held to me escaping / So that your valves should not break / Carried from house to house to ship from sail to train, / So that my enemies might go on talking to me.

There must always be some who are brighter and some who are stupider. The latter make up for it by being better workers.

How can the theatre be both entertaining and instructive at the same time?
