The fundamental lie in the popular view of evolution!
For many people, their understanding of evolution is contained in two phrases:
Darwin’s “Survival of the fittest” and
Huxley’s “Nature red in tooth and claw”.
Both of those ideas can be true, and neither is universal.
Evolution works on differential survival.
What survives, in what contexts, on average, in reality, over time.
Sometimes survival is influenced by ability to compete.
Sometimes survival is influenced by ability to cooperate.
Sometimes survival is just pure dumb luck (random).
How frequently, and to what extent, each of those pressures influences survival, is profoundly important on what develops.
We human beings are a profoundly cooperative species.
Sure we all have a competitive side, that is also true.
If the context demands it, we can all compete.
And if the context allows, we can also cooperate.
And the greater truth is that we are capable of levels of cooperation, to our mutual benefit, that are far beyond any other animal we are aware of.
As individuals, we are each profoundly complex.
We live in social, economic, ecological, political and ethical systems that are profoundly complex and interrelated.
People often search for, and even demand, simplicity in places where there is no simplicity, only profound complexity.
Often we need to glimpse that profound complexity before the need for tolerance and acceptance of uncertainty and diversity can really be accepted and experienced and lived.
