My family had a lot of characteristics - achievements, ambitions, talents, expectations - that all seemed to be recessive in me.

The floor of ice cream parlor bothered me. It was black-and-white checkboard tile, bigger than supermarket checkboard. If I looked only at a white square, I would be all right, but it was hard to ignore the black squares that surrounded the white ones. The contrast got under my skin. The floor meant yes, no, this, that, up, down, day, night -all the indecisions and opposites that were bad enough in life without having them spelled out for you on the floor.

And this was the main precondition, that anything might be something else. Once I'd accepted that, it followed that I might be mad, or that someone might think me mad. How could I say for certain that I wasn't, if I couldn't say for certain that a curtain wasn't a mountain range?

Whatever we call it - mind, character, soul - we like to think we possess something that is greater than the sum of our neurons and that animates us.

There is thought, and then there is thinking about thoughts, and they don't feel the same.

The only way to stay sane is to go a little crazy.

Which is worse, overload or underload? Luckily, I never had to choose. One or Pass on to where? Back into my cells to lurk like a virus waiting for the next opportunity? Out into the ether of the world to wait for the circumstances that would provoke its reappearance? Endogenous or exogenous, nature or nurture - it's the great mystery of mental illness.
