Music is the mirror of reality.

As in private life one differentiates between what a man thinks and says of himself and what he really is and does, so in historical struggles one must still more distinguish the language and the imaginary aspirations of parties from their real organism and their real interests, their conception of themselves from their reality.

Society does not consist of individuals but expresses the sum of interrelations, the relations within which these individuals stand.

Without doubt, machinery has greatly increased the number of well-to-do idlers.

It has drowned the most heavenly ecstasies of religious fervour, of chivalrous enthusiasm, of Philistine sentimentalism, in the icy water of egotistical calculation. It has resolved personal worth into exchange value, and in place of numberless indefeasible chartered freedoms, it has set up that single, unconscionable freedom -- free trade. In one word, for exploitation, veiled by religious and political illusions, it has substituted naked, shameless, direct, brutal exploitation.

The theory of Communism may be summed up in one sentence: Abolish all private property.

The proletarians have nothing to loose but their chains. They have a world to win.
