... morality and religion ... both allow that
if men can make money by stealing men and women, and working them
up into sugar, rice and tobacco, they may innocently continue
the practice, and he who condemns it is an unworthy citizen, and
a disturber of the church. Money is the measure of morality, and
the success or failure of slavery, as a money making system, determines
with many whether the thing is virtuous, or villainous, and whether
it should be maintained or abolished.
