The movement of the middle classes for the abolition of slavery was virtuous, but it was not wise. It was an ignorant movement. It showed a want of knowledge both of the laws of commerce and the stipulations of treaties; and it has alike ruined the colonies and aggravated the slave trade...The history of the abolition of slavery by the English and its consequences, would be a narrative of ignorance, injustice, blundering, waste, and havoc, not easily paralleled in the history of mankind.
