I think that selfishness is a meme implanted in the society due to ideas based on division and separatism, which is basically derived from western European dualism and mechanism. Rugged individualism and the colonial mentality are also symptoms sprung from Cartesian dualism and mechanism. Thus, now that humans are so divided from each other, and have internalized the lies based on keeping us divided from each other and from nature so that we can justify killing, controlling, conquering, abusing, and exploiting others and the planet without compunction or inhibiition, we live in huge fear and distress over attaining our personal needs and security. Feeling as though we have to do this by ourselves on our own puts us in situations and mindsets where the reptile brain is activated, fight or flight, and that has its effects all right, biological, chemical, societal, and ecological. When we are forced to live this way, we become selfish and self-centered. It’s me for mine, not ours for us.
However, I am convinced that this idea that humans are basically selfish is totally false. Selfishness clearly stems from that huge fear and distress based on certain societal assumptions that are actually anti-human and very destructive to everyone and everything. If reality is basically holistic, then humans at root are meant to live together in balance and harmony, and the altruistic “ours for us” mentality is our true and healthy inherent nature. I don’t think this can be proven wrong based on the way our society works today, since it is so dysfunctional and destructive. Dysfunction and destruction are not natural byproducts of our inherent humanity; they are the results of inhumanity, of humans who have been forced or compelled into conforming to conditions which are not natural or healthy. Many many people are deeply disturbed, depressed, and dissatisfied with their lives. Why do you think we are called Psychotrope Nation (aka Prozac Nation)? Why are we stuck in endless wars and occupations that harm and kill so many, including our own? Why do we listen to insanity and vote against our own best interests, unable to think well about what a good, fair, and just society looks like? It’s because we have bought into the lies we have been fed from childhood and haven’t grown up enough to ask our own questions and find our own answers.
The great psychologist Sam Keen said that the sign of maturity is the ability to ask one’s own questions, to go on an individual quest that involves what it means to live in a world where so much killing and destruction is taking place. None of us live in a small tribe any more, separate from the rest of the world. Everything we do affects others everywhere; and everything that happens in the world affects us. We are all part of a holistic nexus in crisis, and until we give up the old, tired notions of separateness and selfishness, the destruction, chaos, dysfunction, and unhappiness will continue.
