There’s no use arguing that modern society isn’t a kind of paradise. The vast majority of us don’t, personally, have to grow or kill our own food, build our own dwellings, or defend ourselves from wild animals and enemies. In one day we can travel a thousand miles by pushing our foot down on a gas pedal or around the world by booking a seat on an airplane. When we are in pain we have narcotics that dull it out of existence, and when we are depressed we have pills that change the chemistry of our brains. We understand an enormous amount about the universe, from subatomic particles to our own bodies to galaxy clusters, and we use that knowledge to make life even better and easier for ourselves. The poorest people in modern society enjoy a level of physical comfort that was unimaginable a thousand years ago, and the wealthiest people literally live the way gods were imagined to have.
And yet.
There are many costs to modern society, starting with its toll on the global ecosystem and working one’s way down to its toll on the human psyche, but the most dangerous loss may be to community. If the human race is under threat in some way that we don’t yet understand, it will probably be at a community level that we either solve the problem or fail to. If the future of the planet depends on, say, rationing water, communities of neighbors will be able to enforce new rules far more effectively than even local government. It’s how we evolved to exist, and it obviously works.
