useful, but are founded also on the principles of justice. Such is the
case with respect to _Slavery_: it has had the concurrence of all
the nations, which history has recorded, and the repeated practice of
ages from the remotest antiquity, in its favour. Here then is an
argument, deduced from the general consent and agreement of mankind, in
favour of the proposed subject: but alas! when we reflect that the
people, thus reduced to a state of servitude, have had the same feelings
with ourselves; when we reflect that they have had the same propensities
to pleasure, and the same aversions from pain; another argument seems
immediately to arise in opposition to the former, deduced from our own
feelings and that divine sympathy, which nature has implanted in our
breasts, for the most useful and generous of purposes. To ascertain the
truth therefore, where two such opposite sources of argument occur;
where the force of custom pleads strongly on the one hand, and the
feelings of humanity on the other; is a matter of much importance, as
the dignity of human nature is concerned, and the rights and liberties
of mankind will be involved in its discussion.

It will be necessary, before this point can be determined, to consult
the History of Slavery, and to lay before the reader, in as concise a
manner as possible, a general view of it from its earliest appearance to
the present day.

The first, whom we shall mention here to have been reduced to a state of
servitude, may be comprehended in that class, which is usually
denominated the _Mercenary_. It consisted of free-born citizens,
who, from the various contingencies of fortune, had become so poor, as
to have recourse for their support to the service of the rich. Of this
kind were those, both among the Egyptians and the Jews, who are recorded
in the sacred writings.[004] The Grecian _Thetes_[005] also were of
