 … justice, in its more abstract or general sense, should be little considered, or little understood, by those who can believe that it is agreeable to the wisdom and goodness of an all-perfect Being to form two species of creatures of equal intelligence and similar feelings, and consequently capable of an equal degree of suffering under injuries, and should consign one of these species as a kind of property to a different species of their fellow-creatures, not endowed with any qualities of mind sufficient to prevent the enormous abuse of such a power. (Macaulay 1783, 158)
