" So much of human suffering stems from having this self that needs to be psychologically defended at all costs. We’re trapped in a story that sees ourselves as independent, isolated agents acting in the world. But that self is an illusion. It can be a useful illusion, when you’re swinging through the trees or escaping from a cheetah or trying to do your taxes. But at the systems level, there is no truth to it. You can take any number of more accurate perspectives: that we’re a swarm of genes, vehicles for passing on DNA; that we’re social creatures through and through, unable to survive alone; that we’re organisms in an ecosystem, linked together on this planet floating in the middle of nowhere. Wherever you look, you see that the level of interconnectedness is truly amazing, and yet we insist on thinking of ourselves as individual agents.” Albert Einstein called the modern human’s sense of separateness “a kind of optical delusion of his consciousness.
