Tannenbaum argues that if Latin American environment were to favor freedom, the British and American were hostile. emancipation may have legally freed the negro. but it failed morally to free the white man, and by that failure it denied to the negro the moral status requisite for effective legal freedom, And I agree because the book gave key points that showed there disagreement to the idea of giving freedom to slaves. in fact the slave trade was very much accepted by everybody at that time, it was legal it was believed that it was the right thing to do even for religion. on the other hand slavery in colonial Brazil was very diffrent from America. Slavery in Brazil was more of a temporary state, slaves would at that time buy their freedom. but in America it was not allowed the colored man would be born or forced into slavery and was only seen as property and not a human being. Tannenbaum's argument is valid, slavery in colonial Brazil was practiced more humanly rather than the Americans.
