"People who put principles before people are people who hate people."
-Aimeric de Sanha Marsao in A Million Open Doors by John Barnes

"We all turn to shit when we die. But not all of us are shit before."
-Nicomo Cosca in Best Served Cold by Joe Abercombe
"The personal, as everyone’s so fucking fond of saying, is political. So if some idiot politician, some power player, tries to execute policies that harm you or those you care about, take it personally. Get angry. The Machinery of Justice will not serve you here – it is slow and cold, and it is theirs, hardware and soft-. Only the little people suffer at the hands of Justice; the creatures of power slide from under it with a wink and a grin. If you want justice, you will have to claw it from them. Make it personal. Do as much damage as you can. Get your message across. That way, you stand a better chance of being taken seriously next time. Of being considered dangerous. And make no mistake about this: being taken seriously, being considered dangerous marks the difference - the only difference in their eyes - between players and little people. Players they will make deals with. Little people they liquidate. And time and again they cream your liquidation, your displacement, your torture and brutal execution with the ultimate insult that it’s just business, it’s politics, it’s the way of the world, it’s a tough life and that it’s nothing personal. Well, fuck them. Make it personal."
-Quellcrist Falconer in Altered Carbon by Richard K. Morgan

And they’ll let you know in a minute: 'It takes two to tango; when I go, you go' "
-Malcolm X, The Ballot or the Bullet
"We want freedom now, but we’re not going to get it saying 'We Shall Overcome'. We’ve got to fight until we overcome."
"Any time you know you’re within the law, within your legal rights, within your moral rights, in accord with justice, then die for what you believe in. But don’t die alone. Let your dying be reciprocal. This is what is meant by equality. What’s good for the goose is good for the gander."

When they get angry, they realize the condition that they’re in- that their suffering is unjust… and that anything they do to correct it… they’re justified."
