The poster spoke of human intelligence, not general intelligence. I was trying to say that emotions are not just simple drivers they are structurally important pieces that we use to represent the world and that we use in all our cognition. I don't think the human intelligence easily can be separated from emotions since our whole system is built around it.

An older but still popular view of the human mind separate the brain and body as two parts. And we also like to separate emotions and intelligence. From my amateur understanding that does not correspond to modern neuroscience, it is all a very integrated system. We usually like clear and separate categories instead of fuzzy complicated integrated systems.
