Natural theology was popular in England in the 18th century and into the 19th century. This type of theology is rooted in the study of the natural world. Today's intelligent design arguments are an echo of many of the ideas from that time period. As a thought experiment motivated by natural theology, I wondered what a political theory developed purely on observations of nature might result in. It turns out that Thomas Aquinas already considered this in the 13th century. He determined that a monarchy was the best form of government using natural arguments. The heart is the primary mover of the body. Bees have a single queen. Reason has power of the soul. So “every natural governance is governance by one” and since “whatever is in accord with nature is best”, a single ruler must be best.
