Before the development of tribal communities, we had a more self-centred sense of what belonged to us, being that our day-to-day fight for survival didn’t allow us the possibility to focus on long-term planning. With the passing of time, we understood that through collaboration and sharing of resources our chances of survival increase. Settlements grew and it was in the interest of everyone within the community to defend it from invaders. History, if over-simplified could be summed up as a complex game of one-upmanship where some people tried to protect their resources while others tried to acquire them. These dynamics repeated until a link between us and our belongings got strongly engraved in our psyche.
