OK, Guildo… now you’ve gone the totally opposite direction. Tolkien was not a physicist, and even if he was, physics certainly doesn’t presume to define good and evil, and if Stephen Hawkings did I would be greatly surprised; now that you’ve mentioned it, I’ll be sure to go through his
public lectures. Tolkien wasn’t a Buddhist either, and while I don’t think he was slavish to the Christian model, I really don’t see much of a Buddhist influence in his work.
In contradiction to your thesis, see Aristotle, Plato, Saint Thomas Aquinas, Bernard Lonergan (to name just a few) for an explanation of how the Good can and does exist without evil.
