angels and demons
Angels are partisans not of Good but of divine creation. The devil, on the other hand, is one who refuses to grant any rational meaning to that divinely created world.
Dominion over the world, as we know, is divided between angels and devils. The good of the world, however implies not that the angels have the advantage over the devils but that the powers of the two sides are nearly in equilibrium. If there were too much incontestable meaning in the world ( angel's power ),man would succumb under its weight. If the world were to lose all its meaning ( the devil's reign ), we could not live either.
So much for good and evil. So much for moderation. So much for purgatory.
Then there's always the cliched 'angel and devil' in your mind, swaying your opinions and manipulating your actions.
The conservative and the liberal.
I've seen many angels in my life. Following the untouchable commandments of life religiously. The rights and wrongs drawn out clearly, never questioning each definition, never doubting life and living life. Outright angels irritates. Blinded by faith of the system?
And it's obvious that the angels dislike the devils.
Rebels who doubt the existence of the system?
Outright devils are extremists. The world can do less with those, say Satan.
We are all devils in our own right and that's the way we like it.
Coming of age, dirt in the world slowly washes off the purity of angels.
We do need these angels around. They are the other end in our equilibrium.
We do need these angels around to make us look more devilish.
