So little actual Thinking, i.e. slow thinking, goes on. We are in Fast thinking mode all the time which should really be called “schematization” not thinking, i.e. reacting based on what we think we already know.
See Daniel Kahneman Fast Thinking, Slow Thinking. I just started reading it. I saw him talk about it at the LA Times BookFair recently http://www.amazon.com/Thinking-Fast-Slow-Daniel-Kahneman/dp/0374275637

For the history of Schematization see U. Eco Kant and the Platypus.
As Heidegger says in What is called Thinking to think is to thank what ever gives thought for the insights that arrive.
