They are both intellectuals. The difference is that Sagittarius is more likely to take a spiritual approach and Aquarius is more likely to take a mental approach. This can obviously be modified by the rest of the chart.
The question is who is more "intellectual," but some are writing about who is more "intelligent." They are not the same thing. Anyone of almost any intelligence level can read and study and acquire enough knowledge in a subject through hard work to qualify as an intellectual.
Intelligence is something you are born with although some studies show that you can moderately increase your intelligence as you get older. There are people with very little education who are quite intelligent. So I think the question is not who has a quicker and brighter mind, but which sign is more interested in learning things and acquiring knowledge.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
