There's a number of Buddhist statements / parables / pithy quotes along these lines, the interdependence of everything in the universe. A picture frame on my desk is beyond insignificant when compared to, say, the Andromeda galaxy, yet both emerge from the same ground of existence.
This observation scales to what I think you're hinting at; at a social and human level, even the most reclusive of us needs the rest of humanity.
Yeah, that's about it. I'm taking a Japanese philosophy class and read somewhere (I forget exactly wear) about the symbolism of rice, then I decided to expand it a bit. Normally, I think of myself as pretty individualistic, but I've been reading quite a bit on Stoicism and Buddhism and it makes me appreciate more how much we all rely on each other, from friends and family to whoever invented computers etc. It's a pretty cool thought, but I haven't really acted on it much, except maye trying to pay attention more to my friend group and making time for them. Are you Buddhist, or have you studied it a lot? It seems like a practical system.
