I feel a bit more comfortable answering this question, rather than the former.
Comparable intelligence is a much better mindset for Me to deal with. The other thread got too tangled in the "education vrs. intelligence" idea that I didn't see as equal. There were a lot of connotations that weren't especially signifigant as the thread went forward.
Having said that, let Me express My particular view on the core issue. Thankfully, to date, I have never considered any of My subs as having a lack of intelligence. They have differed on strengths and weaknesses in different areas, but I have absolutely never considered any of them "stupid". I'm reminded of that old exchange from the movie "The Breakfast Club". (I hope I quote this right.)
"Without physics, there would be no math."
"Without lamps, there would be no light."
If you haven't seen/don't remember the movie, it means that people have different abilities. To Me, that means that intelligence comes in different forms. Different aptitudes for different areas. Someone who is a genius might not be able to construct a lamp. Someone who can constuct the lamp, might not understand how it works. It doesn't make one better than the other. It just makes the abilities different.
Considering that I do not know everything, and there are many areas that I also have weaknesses in, who is to say that I might not be fascinated with the ability to explain physics? Or to create a lamp? I believe it is relative to the person. Not what they know, or don't know..... but where they start and how they wish to learn.
