You don't understand anything until you learn it more than one way.

No computer has ever been designed that is ever aware of what it's doing; but most of the time, we aren't either.

I bet the human brain is a kludge.

Imagine what it would be like if TV actually were good. It would be the end of everything we know.

In general we are least aware of what our minds do best.
