It has been said that one of the greatest attributes of humankind is the want and need to bring order to and better understand the universe and our place in it. To do this, we have qualified, quantified, and categorized just about everything around us and analyzed and ranked the relationships among just about all things.
Take for instance the discipline of biology. Every living thing has been divided and subdivided into genus and species and we have been able to record their interactions among each other. We have even been able to use this knowledge to rank all living things, for example, the food chain.
