Bertolt Brecht

"Poverty makes you sad as well as wise."

"Science knows only one commandment - contribute to science."

"Society cannot share a common communication system so long as it is split into warring factions."

"The law was made for one thing alone, for the exploitation of those who don't understand it, or are prevented by naked misery from obeying it."

"What they could do with 'round here is a good war. What else can you expect with peace running wild all over the place? You know what the trouble with peace is? No organization."

"Why be a man when you can be a success?"
