What degree of "worldly moderation and economical forethought" is needed by a practical statesman in effecting the liberation of slaves, it is no business of mine to discuss.

I however feel assured, that no constitutional statesman, having to contend against the political votes of numerous and powerful slave-owners, who believe their fortunes to be at stake, will ever be found to undertake the task _at all_, against the enormous resistance of avarice and habit, unless religious teachers pierce the conscience of the nation by denouncing slavery as an essential wickedness.
