I need quotes about sanity vs insanity!

From the text:

Across the room from the Acutes are the culls of the Combine’s product, the Chronics. Not in the hospital, these, to get fixed, but just to keep them from walking around the streets giving the product a bad name. Chronics are in for good, the staff concedes. Chronics are divided into Walkers like me, can still get around if you keep them fed, and Wheelers and Vegetables. What the Chronics are—or most of us—are machines with flaws inside that can’t be repaired, flaws born in, or flaws beat in over so many years of the guy running head-on into solid things that by the time the hospital found him he was bleeding rust in some vacant lot.

If somebody’d of come in and took a look, men watching a blank TV, a fifty-year –old woman hollering and squealing at the back of their heads about discipline and order and recriminations, they’d of thought the whole bunch was crazy as loons.
