From the moment of birth, when the stone-age baby confronts the twentieth-century mother, the baby is subjected to these forces of violence, called love, as its mother and father have been, and their parents and their parents before them. These forces are mainly concerned with destroying most of its potentialities. This enterprise is on the whole successful.
— R. D. Laing

Film is more than the twentieth-century art. It's another part of the twentieth-century mind. It's the world seen from inside. We've come to a certain point in the history of film. If a thing can be filmed, the film is implied in the thing itself. This is where we are. The twentieth century is on film. You have to ask yourself if there's anything about us more important than the fact that we're constantly on film, constantly watching ourselves.
Don Delillo twentiethcentury quote

Intellectuals can tell themselves anything, sell themselves any bill of goods, which is why they were so often patsies for the ruling classes in nineteenth-century France and England, or twentieth-century Russia and America.
— Lillian Hellman

In this century the writer has carried on a conversation with madness. We might almost say of the twentieth-century writer that he aspires to madness. Some have made it, of course, and they hold special places in our regard. To a writer, madness is a final distillation of self, a final editing down. It's the drowning out of false voices.
— Don Delillo

When Mozart was composing at the end of the eighteenth century, the city of Vienna was so quiet that fire alarms could be given verbally, by a shouting watchman mounted on top of St. Stefan's Cathedral. In twentieth-century society, the noise level is such that it keeps knocking our bodies out of tune and out of their natural rhythms. This ever-increasing assault of sound upon our ears, minds, and bodies adds to the stress load of civilized beings trying to live in a highly complex environment.
