“Civilization is a limitless multiplication of unnecessary necessaries.”

“Sometimes, the unnecessary is necessary.”

“The ability to simplify means to eliminate the unnecessary so that the necessary may speak. ”

“Don't tell me what's necessary, you presumptupus pup. What's necessary is whatever I wish to do, regardless of how unnecessary it might be.”

“...civilization means, above all, an unwillingness to inflict unnecessary pain... those of us who heedlessly accept the commands of authority cannot yet claim to be civilized men.”

“Nite-Owl: Look, I just meant we took enough unnecessary risks retrieving your outfit this morning...Rorschach: Unnecessary? Cowering down here in sludge and pollution, conjuring names on screens, learning nothing: that is unnecessary. Give me smallest finger on man's hand. I'll produce information. Computer unnecessary. This face, all that's necessary... all I need.”
