Independent

 Right before dozing off, I really questioned a thought that ran through my head. Is there really such thing as independent person or organism? If you think about it and even in plato's theory of society, everyone has a specific job and due to their own jobs, as a whole they function as one properly. So according to plato, if people rely on others abilities is anyone considered independent? And when they say that animals are independent, are they or do they depend on other organisms to get jobs done as well? Something to comment on... want to hear some insight or thoughts......
