Or, rather, by what metric do you determine the value of another human?
I was asking myself this today, after my mother and I got into an argument where she said that I shouldn't determine if somebody can be my friend based on how smart they are. I countered with the twin points that 1) I want to be able to have intelligent conversation with my friends, and being unintelligent hinders one's ability to have intelligent conversations, and 2) I'm just holding them to the same standards that I hold myself to. She then went on about how "not everyone is as smart as you are", to which I wish I had responded,"And not everyone is my friend. Your point?", but I did not, because I did not think of that until the time of writing. Anyways, TL;DR, my mother thinks my standards are too high.
My point with this is, how do you gauge the worth of a human? I think it's by what they can do, and that what they can do is tied to intelligence and experience. But I'd like to hear what you guys think. Am I on to something? Am I dead wrong? Are you one of those terrible New Age parents who think that everyone is equal? If the last question is a yes for you, please go somewhere else, because you're not going to contribute to the debate at hand in any meaningful way.
