I am not entirely sure about this. If we talk about higher degree of intelligence then I can agree to that. But if we are talking about basic intelligence such as when I look at a stop sign from various angles to determine if it is a stop sign, I don’t believe I need emotion. Don’t you agree?
Having said that
I believe you are right that one of the elements should be “Making Decision” which I think I have an idea how the brain makes decision but I won’t discuss the “how” in this posting and will leave it til later. I want to focus on coming up with the fundamental list of elements to define intelligence first.
