Five hundred years ago a person in error was a person searching for the truth.

If what we learn is no more than what we expect to learn, then we have learned nothing at all.

To learn is to incur surprise-I mean really learning, not just refreshing our memory or adding a new fact. And to invent is to bestow surprise-I mean really inventing, not just innovating what others have done.

The trick, of course, is to lose one day and come back to win the next. But that is possible only when we draw healthy pleasure and confidence from our creative processes.
