Looking at the origin of the word it clearly shows that an individual does not make a society. There must be a couple of others bond by a common factor, this could be race, language, work, interest, education, location service or finance.
Another point clearly shown in the definition is that Human beings are basically social beings, constrained by limitations and therefore there is need to be in close contact with others. Giving an example of a family which I may refer to as the first society, human life is one of interdependence and sharing of physical, mental, and spiritual matters. It is this interdependence that we share in the family that comes to be a unifying factor with other people we meet outside our families.
Therefore all societies strive to maintain harmony within to ensure the happiness and safety of their members because it is the primary motive of its formation.
