“And what constitutes evil, real evil, is the taking of a single human life. Whether a man would die tomorrow or the day after or eventually… it doesn't matter. Because if God does not exist, then life… every second of it… Is all we have.”

Discussing the influence of real-life faiths on his work and its religious systems, Authors@Google (August 2011)
Context: I think worship of death is an interesting basis for religion, because after all death is the one universal. It doesn't seem to matter what gods you pray to. We all die, in the real world and in fantasy worlds, and if there was some religion where you did not die I suspect that would be, that god would become very popular. They all promise us eternal life, but whatever.

[Ecclesiastes, 12:13-14, 9]

XII. The origin of evil things; and that there is no positive evil.
On the Gods and the Cosmos
Context: If evil exists it must exist either in Gods or minds or souls or bodies. It does not exist in any God, for all god is good. If anyone speaks of a "bad mind" he means a mind without mind. If of a bad soul, he will make the soul inferior to body, for no body in itself is evil. If he says that evil is made up of soul and body together, it is absurd that separately they should not be evil, but joined should create evil.

Context: Suddenly, however, remedies for something called 'racism' became the order of the day. The word itself, like 'sexism', is of recent coinage and will not be found in any older dictionaries. The civil rights movement, premised upon individual rights, suddenly became the black power movement, premised upon group rights. 'Affirmative action' became a euphemism for the baldest kind of racial discrimination. That whites had long enjoyed preference over blacks was now taken to be a justification for blacks having preference over whites. What was lost sight of was that the evil of the past, whether of slavery or of Jim Crow, was evil not because it was done by whites to blacks, but because it was done by some human beings to other human beings. The purpose of the law was to end evil acts, not continue them in the guise of 'affirmative action'.

Context: The battle between good and evil is a legitimate theme for a Fantasy (or for any work of fiction, for that matter), but in real life that battle is fought chiefly in the individual human heart. Too many contemporary Fantasies take the easy way out by externalizing the struggle, so the heroic protagonists need only smite the evil minions of the dark power to win the day. And you can tell the evil minions, because they're inevitably ugly and they all wear black.
I wanted to stand much of that on its head.
In real life, the hardest aspect of the battle between good and evil is determining which is which.
