You started off alright with this part:
Yes, I would say this is at least largely true.I realized that subjective morality is true because cultures have different morals. If different cultures have different morality, doesnt that mean that there is no common human nature?
I'm no anthropologist or sociologist, but I would wager that there are certain characteristics and morals that are common to all societies and cultures, such as that taking someone's life without good reason is condemned. What's construed as a good reason will vary between societies, of course.There is no commonality amongst humans other than what their culture dictates.
I think you're going a bit too far there. They still have the same hardware and evolutionary programming because they're part of the same species. That contributes a lot. Culture isn't all any given person is; they're also biology.Other cultures are so vastly different to ours that they might as well be aliens not humans.
Now this is where you lost me completely. Because there are, and have historically been, societies with differing, to various degrees, characteristics, all human experience is meaningless? Did I understand that correctly? If so, how did you arrive at that conclusion? It reminds me of the line of reasoning that because you will die one day, nothing matters. The present experience matters. All experience matters. It matters where it happens and when it happens. It matters right at that moment.So in a way everything that humans matter is meaningless because everybody has different ideas and morals.
We're all atoms. Does that mean we're *just* atoms? Everything that I am consists of neural configurations. Yet I am more than those neurons, am I not? Love is a chemical reaction, but we don't look at things on that level unless we're analyzing brain chemistry. Moreover, love is an emotion, a biological function, not a social construct. Marriage, and arguably/possibly homogamy, are social constructs.Love is just a social construct that only some cultures have.
If it's arbitrary as you say, then how is it possible that there is any order in society?Human behaivor is entirely arbritrary. I'm arbritary. My thoughts, ideals and morals are chaotic meaningless nosies that I conjured up.
