What if we just accept that we cannot overcome this “heart of darkness” we find thrusting itself forward? But the more we let it have its way, the easier evil becomes, and the less it bothers us as we go along giving in to it. If that’s just the way we are, why not use it?
Solomon-Kohelet does not defend the Creator, even though he continually acknowledges Him/Her. Instead, he observes (very dispassionately, like a modern social scientist) the world as it is with all its apparently random outcomes. The “good and just” sometimes suffer evil and calamity in the same way as fools and criminals; the unjust and wicked too often seem to live easy, fat, comfortable lives while the innocent, the good, and the just suffer. He never facilely resorts to blaming God for this state of affairs, nor does he ever mention a ‘devil’, a demon, or any other supernatural entity as an instigator; such things just are. But he still has something to say as to why they are as they are, and his insights are right on target to this day.
