The eternal cycle of humanity. The way it has been since the very beginning. Belief or disbelief in God has no bearing upon this cycle. It is how it is and we never grow out of it!
Last time I looked God/Nature isn’t making any kind of new human beings, so the cycle continues. The mental pendulum swings of sanity and insanity. These same swings portrayed in eras of our existence…
We are nothing if not predictable!
