“The veneer of civilization is thin”
I have the following and I quote it in my manual:
“Star Trek: Deep Space Nine: The Siege of AR-558 (#7.8)” (1998)
Quark: Let me tell you something about Hew-mons, Nephew. They’re a wonderful, friendly people, as long as their bellies are full and their holosuites are working. But take away their creature comforts, deprive them of food, sleep, sonic showers, put their lives in jeopardy over an extended period of time and those same friendly, intelligent, wonderful people... will become as nasty and as violent as the most bloodthirsty Klingon. You don’t believe me? Look at those faces. Look in their eyes.
I like this one too:
“People who live in delightful, well-mannered suburbs, who
never have to contest for their lives and property, often fail
to grasp the subtle logic of violence. It is a mistake seldom
made by hardened criminals.”
James Dale Davidson and Lord William Rees-Mogg in THE GREAT RECKONING
