The race that lives in these ruinous cottages, behind broken windows, mended with oilskin, sprung doors, and rotten door-posts, or in dark, wet cellars, in measureless filth and stench....must surely have reached the lowest stage of humanity."

"We discovered that in connection with these figures the German national simpletons and money-grubbers of the Frankfurt parliamentary swamp always counted as Germans the Polish Jews as well, although this dirtiest of all races, neither by its jargon nor by its descent, but at most only through its lust for profit, could have any relation of kinship with Frankfurt."

"The anarchists put the thing upside down. They declare that the proletarian revolution must begin by doing away with the political organization of the state. But to destroy it at such a moment would be to destroy the only organism by means of which the victorious proletariat can assert its newly-conquered power, hold down its capitalist adversaries, and carry out that economic revolution of society without which the whole victory must end in a new defeat and a mass slaughter of the workers similar to those after the Paris commune."
