Yaknow, this might sound silly, but one of my life's most profound philosophical epiphanies occurred while watching (of all things) Star Wars Rogue One. It was when Lyra Erso told Orson Krennic, right before she was murdered, "You will never win."
It occurred to me that moment the absolute truth of that statement. Good and evil are locked forever in an eternal battle from which neither can ever win. But at the same time, the path of progress is inevitably, albeit tragically incrementally, towards the good.
But the lesson to be learned is that every victory for evil is in fact a misstep that can be used to benefit the good.
This is truth. Evil can never win. Because we won't let it.
Seems like, also, the universe has and will exist for all of the time there is. That's not much of a victory for evil, seems to me.
If you take a nervous system designed to protect body integrity by avoidance of pain and reproductive assurance by attraction to pleasure and throw on top of that a capacity to name, to differentiate, by linguistic capacity, you will arrive at the world seen as duality, a duality that without language would not exist. It is no mystery to me, then, having experienced this as a prime revelation of my youth that the war between good and evil really does not exist. To awaken is to experience the oneness of everything, in my opinion.
Where I see the upward climb relates to how deeply one can maintain such awareness, to what extent a mind can abandon attachment to thought.
Not to worry that evil will win, however achieved, sounds to me like a big step. Thought is fear, and fear is nagging worry and endless grievance, the constant attempt to escape a boogieman of our own creation that does not actually exist.
