I'm not sure I understand what you mean. Are you speaking of just having more variety of human beings so as to facilitate more diverse social interactions?

No, I am talking about the fact that those inspirations you were talking about are, in my opinion, more influenced by people in general than people of the other sex. I am not sure I can explain it better but in two words, I don' t think men are of inspiration for women more than other women, and I don' t think that women are of inspiration for men more than other men. It' s simply that they are different people who can bring the desire in ourselves to compete or be social with them.

That' s why I said that if we were mono-sex we would behave the same way: if there were only males or only females, we would have the same behaviours, because what we are seeking is comparing ourselves to others not to ones of the other sex specifically.

I would think they have other purposes, but it's harder for me to see what they are as they relate to biology. My idyllic side wants to believe that there is more to our purpose in life, but the rational side of me sees procreation as the fundamental purpose we have.

I think our fundamental purpose is to survive until we die more than reproduction. Same goes for any other animal, by the way. I know it sounds cynical but I don' t (surprisingly) mean it that way: we fill our lives with things to make sure that we are happy-ish enough that we want to keep going for as long as we can. That means goals, passions, social interactions, ambitions, whatever you can think of. I think reproduction is mid way between those goals etc... and purpose of life, because it can' t be as trivial as a hobby, but I also don' t think it' s as important as self-preservation and survival.
