The stable functioning of a society depends upon the relatively long-term stability of the goals of its citizenry. 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 satisfaction of its citizenry, and it is obvious that a society is stable only if its laws tend to increase the happiness of its citizens.
The underlined part of the argument serves which one of the following roles in the argument?
