Childlike curiosity is innocence, it is in no way ignorance. When we believe we know something, when we don't, that is ignorance. And it is ignorance because we've stopped looking - preferring instead our "knowledge" - our believed memories and concepts.
Take your kid for a walk through the forest. He's curious and says "what's that?" We tell him that's an ant's nest. We define it in a word. The danger is our kid believes us, believes that's all he needs to know, and then stores that away as a memory of truth for retrieval. Next time he sees an ant's nest the thought may implicitly arise - "oh that's another ant's nest, I already know that. Nothing to learn there". There is a sense of certainty and competence, but it is only an illusion. The label is not the object. And in the knowing, the enquiry is lost. He may stop looking, instead looking for the next label to remember. So he looks at the ant's nest, and the world, through his sets of memories and concepts and labels. Not really even looking any more at the ant's nest, or the world. The innocence is lost.
"Grown-ups on the other hand have a responsibility to figure out what is happening." Are you confusing labelling and categorising (intellectual knowing) with experiencing and enquiring (intuitive knowing)? Is our intellect our tool or our master? And how is it that children learn so much faster than adults? Do they figure out what is happening through their natural curiosity and enquiry - or do we need to treat them as information machines, sit them behind desks and pump "expert" information into them?
Our schools are fundamentally belief-acquisition mechanisms. Yes? Captain Cook discovered Australia in 1770. Integrate x and you get x squared divided by two plus c. Chlorophyll is the green pigment in plants which converts sunlight into usable energy. The student encouraged and rewarded is the one who blindly follows the belief system and regurgitates the accepted "truth". Very religious process. Einstein was seen in school as lazy, slow, quite untalented and would never amount to anything. The school system tends to churn out unmotivated, deadened robots. And depression and suicide only increase every year, despite all the expert "best practice" drugs we throw at the known "chemical imbalance" problem. We become unable to really think for ourselves, openly and creatively. The schools are our modern-day church institutions.
Yet children seem to learn best through enquiry, not belief. Which method is more enlivening for our children?
In a world which constantly changes, and is ambiguous and multidimensional, which child becomes best equipped to deal with change? Especially major change. The information collector or the open enquirer? Which path is the more responsible?
