The stable functioning of a society depends upon the relatively long-term stability of the goals of its citizens
This is clear from the fact that unless the majority of individuals have a predictable and enduring set of aspirations, it will be impossible for a legislature to craft laws that will augment the satisfaction of the citizenry, and it should be obvious that a society is stable only if its laws tend to increase the happiness of its citizens
It helps to support the conclusion of the argument.
