Candide is about what to do with a world that has evil in it as well as a real rip on philosophers and the clergy and the elites in Europe.
The evil thing has me thinking about our views of NATURE today. Nature documentaries and children's books always locate evil in the great white shark or the big bad wolf. But of course our modern, scientific point of view recognizes that dramatic ideas of good guys and bad guys are just human constructs. The wolf is no more evil than the mosquito -- both might be a problem for us but they are part of a large ecosystem. But NATURE has no moral framework. So where do we get this moral framework from. We seem to have a basic sense of FAIRNESS, but we know that life is not FAIR. But still we cling to it. Is that were GOD resides?
