Vygotsky believed that upper mind thinking was directly related to social activity and had no biological affects after early age development.
In later analysis, Vygotsky seems to point to religion as a source for the upper mind to prove itself more knowing or powerful than others.
Could this be the reason for folks like Reverend Jim Jones to take his cultish belief to such extreams. (Power)
Do folks find power in knowing God, Yaweh, etc.?
