“I have always had something to live besides a personal life. And I suspected very early that to live merely in an experience of, in an expression of, in a positive delight in the human cliches could be no business of mine.”

“My heart is warm with the friends I make,
And better friends I’ll not be knowing,
Yet there isn’t a train I wouldn’t take,
No matter where it’s going.”

“Knowledge in the form of an informational commodity indispensable to productive power is already, and will continue to be, a major—perhaps the major—stake in the worldwide competition for power. It is conceivable that the nation-states will one day fight for control of information, just as they battled in the past for control over territory, and afterwards for control over access to and exploitation of raw materials and cheap labor.”
—Jean François Lyotard (b. 1924)
