A man who sees another man on the street corner with only a stump for an arm will be so shocked the first time he'll give him sixpence. But the second time it'll only be a three penny bit. And if he sees him a third time, he'll have him cold-bloodedly handed over to the police.
Bertolt BrechtFor time flows on, and if it did not, it would be a bad prospect for those who do not sit at golden tables. Methods become exhausted; stimuli no longer work. New problems appear and demand new methods. Reality changes; in order to represent it, modes of representation must also change. Nothing comes from nothing; the new comes from the old, but that is why it is new.
Bertolt Brecht
