I want to revisit the idea that humans need social ties and that the pain we feel when socially isolated is ingrained in us as a product of our evolution. I think it is a given that we cannot exist in this world without “others”: We, at the very least, need some adult person to care for us as children. This role is typically played by one or two parents or by another close relative or family friend.
But even as adults, we need other people too - a single individual cannot possibly do for oneself what one must need to do on a daily basis just to survive – eat, drink, maintain shelter, protect oneself from harmful influences in the outside world, etc. People who think they are doing these things on their own are mistaken – does anyone you know actually hunt/gather their own food before cooking it for themselves to eat? Do you stake out your own land, build shelter on it, and then protect it from invasion/theft? In contemporary industrialized societies, many people purchase food that has already been hunted/gathered, processed, and sometimes even prepared by other people. We purchase land or rent it from others, often with a structure already on it, which was built by someone else. We can go to sleep at night feeling safe because the police department, laws and social norms, and the justice system provide very effective (even if not perfect) protection from harmful outside influences. Thus, even the “anti-social” introvert is heavily dependent on others for daily life and survival.
Humans *need* one another. We could not survive without each other. This is ingrained in us. To be wholly socially isolated (which, arguably, nobody actually is) would result in one’s demise. Thus, it is ingrained in us as a product of our evolution to be social creatures. Hence, we feel pain when socially isolated.
A future topic for discussion will look at one of the negative aspects of this evolutionary product – namely, what happens when the human need for socialization and social connection forces people into adopting identities that are not truly their own.
