Wisdom exists, but there is no guarantee humans will always choose its teachings.
For deep in the psyche lurks our demons of extinction knowing we do not occupy the top spot on the food chain. This natural urge of self preservation is the cause of our unfounded fears which lead us to unnaturally divide and weaken the human species into castes, class, countries, religions, races and tribes.
Self preservation ought to prove to us that the human gene’s best chance of survival and progress lies in diversification.
So before we raise our consciousness of justice and fairness, our innate conservative nature ought to lead us to structuring ourselves for free movement and co-existence, first with each other, and then with our surrounds.
