It starts with humility and a fundamental principal: Question Everything. I scoff at the bumper sticker because it’s far deeper than that and, obviously, there are things you must stop questioning to be able to operate in reality. The big HOWEVER is that childhood offers the space and natural inclination to question everything.
I remind my children constantly that I am not the authority on knowledge. When we access information, we approach it as loving, curious skeptics.
This sucks. My children are constantly challenging me and that can be inconvenient, uncomfortable, and/or plain ole annoying.
We socialize with a wide variety of people of differing religions, philosophies, politics, and cultures. This exposes us to ways of thinking we would not encounter in a “curriculum” or any system of education. We listen first, then try to ask questions with an open heart.
This has lead to a greater understanding of, and appreciation for, our fellow humans.
