“Eighth Doctor: I love humans. Always seeing patterns in things that aren’t there.”

“It’s not love. It’s an obsession. And it’s not art. It’s a way of seeing things. A way to see the things that aren’t there.”

“To find love is the great human undertaking...and it's always complicated by our compulsions and unconscious patterns, to say nothing of issues of trust and control.”

“Aren’t the scariest things in lifeThose things you can’t see?”

“They're so attached to their patterns that they've forgotten rule number one of human behavior: there are no patterns. People just do things. There's no such things as a coherent and fully integrated human personality, let alone consistent motivation.”

“It’s always our mistakes, the things we aren’t proud of, that are the first ones to stand up, ready to be counted. That’s human nature and it’s not going to change, not for me or for you, either.”
