Society is the term to describe human beings together (collective, the sum of their social networks and power networks). It does not refer to everything everybody thinks or does, but only to those things that everybody acts upon – or refuses to do – quite reliably.
Because it must keep even the poorest and weakest members of a society willing to help even the richest and strongest, a society is very concerned with its citizenship, rights, ethics and time limits. These are basic ways to achieve fairness. If they break down badly, people will think the society is unfair and start taking things from each other, refusing to help each other, or seeing those who have more as cheats.
While every society is different, the way it breaks down and fails is very often the same: fraud, theft, violence, war and sometimes even genocide if people stop identifying with the society and thus identify with what they think of as a "race" of people. A new society may be formed out of only those who still agree, or who just survive the collapse of an old failed one.
