Epicurus of Athens was always a very controversial figure, even before he was a heretic in the middle ages. He was a very popular figure, but he was yet another philosopher vilified by early Christianity. His inclusion in this chapter is interesting, as he founded Epicureanism, a school that inspired Sextus Empiricus' school of empiricism, from which the modern scientific method is derived. Bringing up a philosopher who fought against superstition and the idea of divine intervention, especially in the context of a priest teaching the nature of rainbows to children, is an inherently clever choice.
