[Footnote 3: The conditions that regulate the authoritative enforcement
of actions, are exhaustively given in works on Jurisprudence, but they
do not all concern Ethical Theory. The expedience of imposing a rule
depends on the importance of the object compared with the cost of the
machinery. A certain line of conduct may be highly beneficial, but may
not be a fit case for coercion. For example, the law can enforce only a
_minimum_ of service: now, if the case be such, that a minimum is
useless, as in helping a ship in distress, or in supporting aged
parents, it is much, better to leave the case to voluntary impulses,
seconded by approbation or reward. Again, an offence punished by law
must be, in its nature, definable; which, makes a difficulty in such
cases as insult, and defamation, and many species of fraud. Farther,
the offence must be easy of detection, so that the vast majority of
offenders may not escape. This limits the action of the law in
unchastity.]
