All things are learned from Exposure. Experiences from the perceived insignificant to the life altering, life changing events that sear into the memory. In order for the mind to grow it must be stimulated, introduced to new and or different ideas, perspectives. Allowing one to step out of their comfort zone, the social norms perpetuated by a society that see through an established, fixed, rigid wimdow, is the beginning of cognitive growth. There is meaning, validity to "Each one, teach one, each one, reach one..." The question is has this been done? How do we become open to the not so obvious, the covert? Exposure... to the end of the horizon.
