selves the enemies of the human race.
Poisoners, assassins, and incendiaries by profession may be exterminated
wherever they are seized; for they attack and injure all nations by
trampling under foot the foundations of their common safety. Thus
pirates are brought to the gibbet by the first into whose hands they
fall. If the sovereign of the country where crimes of that nature have
been committed reclaims the authors of them in order to bring them to
punishment, they ought to be restored to him, as to one who is
_principally_ interested in punishing them in an exemplary manner: and
it being proper to convict the guilty, and to try them according to some
form of law, this is a _second_ [not sole] reason why malefactors are
usually delivered up at the desire of the state where their crimes have
been committed."--Book I. ch. xix. Sec.Sec. 232, 233.

FOREIGN MINISTERS.

"The obligation does not go so far as to suffer at all times perpetual
ministers, who are desirous of residing with a sovereign, though they

what is for the good of the state ought unquestionably to be preferred:
and the foreign sovereign cannot take it amiss, if his minister, who has
concluded the affairs of his commission, and has no other affairs to
negotiate, be desired to depart.[43] The custom of keeping everywhere
ministers continually resident is now so strongly established, that the
refusal of a conformity to it would, without _very good reasons_, give
offence. These reasons may arise from _particular_ conjunctures; but
there are also common reasons always subsisting, and such as relate to
_the constitution of a government and the state of a nation_. The
republics have often very good reasons of the latter kind to excuse
themselves from continually suffering foreign ministers who _corrupt the
citizens in order to gain them over to their masters, to the great
prejudice of the republic and fomenting of the parties_, &c. And should
they only diffuse among a nation, former
