I think it's a given how as children we have that 'knowing' or that sense of what's true or not, that's why children never lie or if they do it won't take long til they spill the beans or reveal it through their eyes... you'll see how open they are really. But I'd like to think that we're all kind of explorative beings too, because when you tell kids something they'll somehow seek to find out what the opposite is like or react adversely. That's probably why they call it 'reverse psychology' in the academe.
We are all, as Einstein terms it 'passionately curious'. Just wanting to learn and seek out the answers to our own questions , see what we don't see or know what we don't know, experience what we haven't experienced no matter what the cost or circumstance, it is this intuitive mind and this open heart that makes this path what it is, and constantly sets us free.
