This is a fascinating subject. We see that even babies are social as they communicate in their own way. So do animals. I love to watch my pets as they interact. By their actions, I even think that they can read each other's minds.
I remember abstract thinking as a toddler. I remember learning to talk, I thought it was a great challenge. And I remember once that challenge was conquered being disappointed. When I hear a baby talk, it sometimes brings back those memories. I have tried to get it back, although my thinking now is linear. When we come into the world we still possess the knowledge of the universe. I was much wiser then than I am now. It is such a shame that we are taught to think in a certain way in order to blend in to society.
Yet that baby has its own language when it needs something. We are indeed social creatures. We need to maintain a balance of work, play, being with people, and spending time alone, maybe reflecting inwardly to find out who we really are.
