“I've always thought that love was being foolish and stupid. It's about being on the edge and I like being on the edge. It's not divine madness like some people think, there's no such thing as divine madness, madness is just madness. Love is hallucinating without drugs.”

“He may be mad, but there's method in his madness. There nearly always is method in madness. It's what drives men mad, being methodical.”

“There is always some madness in love. But there is also always some reason in madness.”

“He is mad about being small when you were big, but no, that's not it, he is mad about being helpless when you were powerful, but no, not that either, he is mad about being contingent when you were necessary, not quite it... he is insane because when he loved you, you didn't notice.”

“My mom's a mad scientist. It's a lot like being a regular scientist, except without worrying about legal or moral limitations, and it's a commom profession among the scientifically inclined supervillain.”

“When you fall in love, it is a temporary madness. It erupts like an earthquake, and then it subsides. And when it subsides, you have to make a decision. You have to work out whether your roots are become so entwined together that it is inconceivable that you should ever part. Because this is what love is. Love is not breathlessness, it is not excitement, it is not the desire to mate every second of the day. It is not lying awake at night imagining that he is kissing every part of your body. No... don't blush. I am telling you some truths. For that is just being in love; which any of us can convince ourselves we are. Love itself is what is left over, when being in love has burned away. Doesn't sound very exciting, does it? But it is!”

“Stay mad, but behave like normal people. Run the risk of being different, but learn to do so without attracting attention.”
