peaceable existence among us. A day of revolution must come, and it is
our duty to prepare for it. Its threatened evil may be changed into a
national blessing. The establishment of schools for the instruction of
the slave children, a general diffusion of the lights of Christianity,
and the introduction of a sacred respect for the social obligations of
marriage and for the relations between parents and children, among our
black population, would render emancipation not only perfectly safe, but
also of the highest advantage to the country. Two millions of freemen
would be added to our population, upon whom in the hour of danger we
could safely depend; "the domestic foe" would be changed into a firm
friend, faithful, generous, and ready to encounter all dangers in our
defence. It is well known that during the last war with Great Britain,
wherever the enemy touched upon our Southern coast, the slaves in
multitudes hastened to join them. On the other hand, the free blacks
were highly serviceable in repelling them. So warm was the zeal of the
latter, so manifest their courage in the defence of Louisiana, that the
present Chief Magistrate of the United States publicly bestowed upon them
one of the highest eulogiums ever offered by a commander to his soldiers.

Let no one seek an apology for silence on the subject of slavery because
the laws of the land tolerate and sanction it. But a short time ago the
slave-trade was protected by laws and treaties, and sanctioned by the
example of men eminent for the reputation of piety and integrity. Yet
public opinion broke over these barriers; it lifted the curtain and
revealed the horrors of that most abominable traffic; and unrighteous law
and ancient custom and avarice and luxury gave way before its
irresistible authority. It should never be forgotten that human law
cannot change the nature of human action in the pure eye of infinite
justice; and that the ordinances of man cannot annul those of God. The
slave system, as existing in this country, can be considered in no other
light than as the cause of which the foul traffic in human flesh is the
legitimate consequence. It is the parent, the fosterer, the sole
supporter of the slave-trade. It creates the demand for slaves, and the
foreign supply will always be equal to the demand of consumption. It
keeps the market open. It offers inducements to the slave-trader which
no severity of law against his traffic can overcome.
