4. “I actually did the work on
the paper,” [Feynman] said.
“Well,” Weiner said, “the
work was done in your head,
but the record of it is still
here.”
“No, it’s not a record, not
really. It’s working. You have
to work on paper and this is
the paper. Okay?”
—Genius, by James Gleick, pp 409

9. What is thinking?

10. 34 + 4 = ?

11. 34 x 4 = ?

12. 34 4 =?

14. Where does

22. brain bound

23. Parity principle
If some process works in a way that
we would count it as cognitive if it

should count it as cognitive if it is
done outside the head.

24. 34 4 =?

Act on the world to achieve
a desired goal-state in the
world

35. Epistemic Actions
make mental computation
» faster
» simpler
» less prone to error

Act on the world not for the
change in the world, but for
the change in you
