Within the city, issues of good and evil are everywhere present. They are manifested in the lives of the citizens. The state, in its Augustinian concept, exists primarily to mitigate the enormous power of evil that occurs in public life through the actions of individual citizens within it. This idea is more complicated because the state apparatus itself may be the source of the greatest of the evils. “Who shall watch the watchdogs?” is a political saying of great moral insight. The rulers are themselves human beings subject to original sin.
Actual cities are in part the domain of justice. The first responsibility of a civil society is to provide for at least a minimum of just order. This responsibility will include the power of coercion, that is, courts, army, and police. At present in the world, we find perhaps two hundred political entities, most of which have within them subsidiary bodies that carry out various functions of justice and order.
Aristotle and Plato did not think that politics and economics were the same. The provision of material well-being was not the primary function of the polity, though everyone recognized that such things needed to be provided. Producing and distributing sufficient food, clothing, and shelter for a people on a massive scale is a modern invention. Generally, we know how to do this. If people have not a sufficiency in basic areas, it is most often due to political or ideological reasons or moral corruption, not to a lack of knowledge about how such goods are produced. Many refuse to learn or apply what is known to produce what is necessary. They prefer dishonest means.
Arguments between free markets and socialism persist. The political order is usually a support for the economic order and should not itself become identified with it. The relationship between the two is mutual; both need each other.
Both the Old and New Testaments presume that “the poor” will always be with us. Yet the relative riches of others can make us feel poor even if we already have what we need. The requirements of neighbors are looked on both as individual responsibilities and as political ones. Indeed, one of the most obvious things that give glory within the city is its capacity to assist citizens in their basic needs.
The proper way of any political order to provide for everyone is to enable people to help themselves. Looked at in this way, our aim is not to help someone else but to enable everyone to help himself in a fair exchange.
