"Everyone has their own way of changing, or, what amounts to the same thing, of perceiving that everything changes. In this matter, nothing is more arrogant than trying to dictate to others."
-- Michel Foucault

"The philosophers have only interpreted the world, in various ways; the point is to change it."
-- Karl Marx

"If there is no struggle, there is no progress. Those who profess to favor freedom and yet avoid confrontation, are people who want crops without plowing up the ground; they want rain without thunder and lightning; they want the ocean without the roar of its waters."
-- Frederick Douglass

"Never doubt that a small group of thoughtful, commited citizens can change the world. Indeed it is the only thing that ever has."
-- Margaret Mead

"Those who make peaceful revolutions impossible will make violent revolutions inevitable."

"We may conclude this section by stating that, in general, low pressures favor dissociation processes while high pressures favor combination processes."
-- Enrico Fermi in Thermodynamics, 1936, on Le Chatelier principle

"Shall I project a world?"
-- Thomas Pynchon in The Crying of Lot 49

"She had heard all about excluded middles; they were bad shit; to be avoided, and how had it ever happened here, with the chances so good for diversity? For it was now like walking among matrices of a great digital computer, the zeroes and ones twinned above, hanging like balanced mobiles right and left, ahead, thick, maybe endless. Behind the hieroglyphic streets there would either be a transcendent meaning, or only the earth."
-- Thomas Pynchon in The Crying of Lot 49
