Aristotle's "Politics" is full of deep insight: politics as the architectonic science, the mixed constitution, happiness as the end of the city. But, there's a group which is excluded from human virtue; namely, the natural slave. Alex Denley and Dr. Andrew Jones discuss how the "natural slave" reveals the structure of Aristotle's just city: a limited class of citizens over an unspecified amount of slaves. And, that the despotic relationship extends into the mixed constitution of the citizens. The masses believe they are ruling in a democracy, the notables believe they are ruling an oligarchy, and the one true philosopher-statesman rules the whole; each class instrumentalizes the other. They discuss how this doesn't vilify Aristotle, or presume nefarious intentions; this is what a science of a pagan political order demands. Ultimately, it is this structure that Christianity transforms from both within and above.
