I had the chance to hold a precious little baby girl in church. She may have been almost one year old at the most. Being that I had just been overwhelmed with information for my test, I couldn't help but watch all of the characteristics Piaget described in his theory.
What's perhaps most profound is the fact that, despite the fact that children have always done this, no one else had noticed the pattern and realized its implications prior. If they did, I don't know of this.
So, I wonder what else lies in everyday occurrences that have yet to be "discovered?"
