Our scribblings are usually not lyrics but whirrings, without colour or resonance, like the tone of an engine-wheel. I believe that the cause lies in the fact that when people write, they forget for the most part to dig deeply into themselves and to feel the whole import and truth of what they are writing.

The working classes in every country only learn to fight in the course of their struggles...Social democracy...is only the advance guard of the proletariat, a small piece of the total working masses; blood from their blood, and flesh from their flesh. Social democracy seeks and finds the ways, and particular slogans, of the workers' struggle only in the course of the development of this struggle, and gains directions for the way forward through this struggle alone.

Freedom for supporters of the government only, for members of one party only no matter how big its membership may be is no freedom at all. Freedom is always freedom for the man who thinks differently.

The existing legal constitution is nothing but the product of a revolution. Revolution is the act of political creation in the history of classes, while constitutional legislation is the expression of the continual political vegetation of a society.

Freedom is always and exclusively freedom for the one who thinks differently.
