Where does intelligence originate?

 One of the fascinating issues in chess development, is that it helps you to observe what is going on in your mind.

Between two chess exercises, I tend to relax with a simple game. I must shift wooden blocks, in order to free a Christmas present. The intelligence I use to do that, is originated in system 1. It is quite smart but not perfect, and it is lightning fast. It is strange, since I don't consider it to be my intelligence. Well, I claim positive results of it of course as a result of my intelligence, but I do not have the feeling that I have contributed to it. My usual verbal thinking is not and has not been involved. And I cannot remember that I accumulated that intelligence in the past. I certainly haven't invested in it consciously.

It is very strange to have a second intelligence inside.
