So, its pretty obvious, that there are some philosophical thoughts in BAA and not only some self made thoughts but theories by known philosophers. Or at least great "theorists".
For Example the whole discussion about "freedom":
In the beginning, you could say, freedom is at least having a body again

In the hunter-warrior arc, with Yugo, freedom is to have a dream and follow it a 100%.
In the tuned- arc, its defined as: the stronger you are, the more freedom you have (exemplified on Foggier and Jorg (his companion, I only know his german name...).
We also see this at the begining of LAst Order, when Nova asks Alita, what she will do now, being the strongest person on earth.
Later on in Last Order more and more the element of responsibility comes into the story.
Im not very deep into philosophy, but the theorie of having freedom but also having resposibility with that sounds like Sartre or maybe Heidegger (roughly said: existentialism, but maybe I mistook this...).
So one could say, that in the beginning its more darwinistic (survival of the fittest), while later its going to be like the existentialism.
But like I said, I dont know this much about philosophy, it just crossed my mind. Is it overinterpreted or did you find other hints of theories?
And at least we all know, that Kishiro seems to be quite literate regadring SciFi- theories or psycological topics..
