It is principally reserved, when not abused, for a select class of utilities.
Some utilities are indispensable to the very existence of men in society.

The primary moral duties must be observed to some degree, if men are to live together as men, and not to roam at large as beasts.
The interests of _Security_ are the first and most pressing concern of human society.

Whatever relates to this has a surpassing importance.
Security is contrasted with Improvement; what relates to Security is declared to be Right; what relates to Improvement is said to be Expedient; both are forms of Utility, but the one is pressing and indispensable, the other is optional.

The same difference is expressed by the contrasts--Being and Well-being; Existence and Prosperous Existence; Fundamentals or Essentials and Circumstantials.

That the highway robber should be punished is a part of Being; that the highways should be in good repair, is a part of Well-being.
