“All living things contain a measure of madness that moves them in strange, sometimes inexplicable ways. This madness can be saving; it is part and parcel of the ability to adapt. Without it, no species would survive.”

“What I was thinking, in that strange way you can think without words while you are dancing, think in glyphs, think in numbers, was how stupid it is that any of us are here, living. What an absurd game we play with ourselves, as if it mattered. We are all mad, all insane, all deluded. It is all for nothing, really, in the end.”

“Tool wondered if the girl was going mad. It happened to people. Sometimes they saw too much and their minds went away. They lost the will to survive. They curled up and surrendered to madness.”

“You can be as mad as a mad dog at the way things went, you can curse the fates, but when it comes to the end, you have to let go.”

“People only get married when they've no other option, out of panic or desperation or so as not to lose someone they couldn't bear to lose. It's always the most conventional things that contain the largest measure of madness.”
