You can't think about thinking without thinking about thinking about something
— Seymour Papert
Seymour Papert used to say "You can't think about thinking without thinking about thinking about something". In other words, it will really help to have important issues and ideas, and things to learn about that require much better thinking. Then, the many things that are known about thinking, how poorly we are generally at it, and what we've learned about doing it better, can be brought to bear.
